"We're approaching our destination!" I called out to the passengers as the vehicle expertly wove its way through the massive black trees that seemed to climb for miles above our heads. You could barely make out the deep purple sky as most the light had been blocked out by Sam's denim jeans. Luckily both the vehicle and the guests had been equipped with high powered flood lights capable of lighting up even the darkest areas. As I carefully maneuvered the vehicle through the thick jungle of Sam's pubic hair, the massive silhouette of our destination rising up in the horizon.

Today was a special tour reserved for only our most frequent guests. After polling the members from out special tour frequent shrinkers club, "Journey Under the Clitoral Hood" won hands down as the most requested tour choice. Any boyfriend would feel apprehensive asking their girlfriend if he could take a group of thirty people to explore the inside of her clitoral hood, and I would have as well if it hadn't been for the fact that this choice had been Sam's suggestion.

I slowed the vehicle to a crawl as I carefully navigated the ridges of Sam's clitoral hood in an attempt to find my way inside. I swallowed deeply as my eyes trailed downwards to the seemingly endless chasm between Sam's legs beneath us. To pull this off, we had to shrink smaller than usual in order to fit the vehicle inside the gap without hurting Sam. If I had been alone I may have attempted the trek on foot, but with thirty tourists of varying athletic abilities, I really didn't want to risk losing any members down in the depths of her panties. I had been given a grim reality check only a few months prior to the importance of making sure every member of the tour was accounted for at all times.

Finally, with maneuvering skills that could only be achieved after years of travelling over every inch of my beautiful girlfriend's body, Sam's massive clitoris came into sight, carefully hiding beneath the folds of her massive clitoral hood. Sam's ability to act unaware had obviously improved over the years as she had somehow managed to keep from letting her clitoris become erect this long in spite of her hormones obviously racing right about now. That being said, even relaxed, Sam's clitoris was far more massive to us than any mountain we would see normally.

Driving deep into the folds of Sam's Clitoral hood, I put the vehicle into park before turning to the tourists on board.

"We have made it to the deepest part of Mount Clitoris!" I announced proudly. "As promised, you will all have 30 minutes to wander around, looking for any souvenirs you may want to take with you as well as taking any pictures you may want to commemorate today by. Considering our location, I suggest staying fairly close to the vehicle at all times as we may need to make an emergency escape from this location. She may not know we are here, but tiny or not I am sure being so close to the depths of her clitoral hood is having some effect on our giantess today!"

As if on cue, the world around us shook violently as the massive clitoris twitched slightly beside us. If we were normal sized, this twitch would barely be visible, but as small as we were it was as if a massive earthquake had shaken us to our core.

In spite of this, the tourists on board did not get cold feet. In fact, they seemed more excited than ever to get out there knowing that their actions may be putting the unaware giantess into waves of pleasure with no idea as to why. These were clearly veteran tourists.

"I just want to take the time before we head out to thank each and every last one of you." I explained feeling somewhat sentimental. "We take many people on tours here at Giantess Tours, but it is you frequent shrinkers who make it all worth it."

Looking around I smiled as I saw a young mother and a few young adult girls who had joined me on that first tour of Sam so many years ago. When I had originally announced this tour service it had been as a one time event to help me get out of a jam. But now, years later, it had become my main source of income and focus of my life. I was thankful for all of the opportunities I had had, as well as tourists like these who had kept coming back this long. Most of all however, I was thankful for my beautiful giantess Sam who had supported and encouraged me through all of this. If I could spend the rest of my life exploring her body, I would die a happy man.

Opening the doors, the tourists wasted no time grabbing their bags, cameras, and collection tools to explore the dark crevice of Sam's clitoral hood. Once they had all left I hopped off my seat to follow them, but not before pressing a button to alert Sam that it was safe for her to stand up again.

Notification sent, I left the vehicle to delve into the warm musky familiar depths of my giant girlfriend's clitoris

-------------------------------------------------------------------------------------------------------

Hearing the notification on her phone, Sam picked herself up from the couch. In order to ensure the safest drive, she had spent the last twenty minutes lying on the couch with her butt slightly raised which was starting to get uncomfortable. The bigger relief however, was that this meant she would no longer be forced to try and suppress the arousal that had been ever growing beneath her pants.

In spite of being famous as an "Unaware Giantess" whose every nook and cranny you could explore without her knowing, Sam had become incredibly sensitive to feeling where the tiny tourists were on her body at all times. Today being a special event of sorts, Ken had taken the scenic route to get to their destination. (In all honesty, it had been because he knew he would most likely need to cut the actual tour short due to Sam's hornyness but the scenic route sounded nicer on paper!)

Sam had felt the tiny vehicle travel along her throat. She felt them drive through the valley of her cleavage. It took every ounce of her effort not to giggle as she felt them drive along her long toned belly. Due to her angle she had been forced to flex slightly and as such they had traveled down the crease of her abs. She wasn't super muscular, but at their size it must have been like driving through a canyon!

A shiver had gone through her spine as she felt them drive along the crease of her hips under her jeans and panties, and she struggled to keep herself from getting wet as they slowly traveled through her pubic hair towards her clitoris.

The final nail in the coffin however had been when she felt them drive in to her clitoral hood like an irresistible tickle that sent a wave of pleasure through her entire body. She couldn't help herself at that point and let herself enjoy it just a bit. She wondered what kind of cataclysmic effect her tiny twitch would have on the full tour!

Now with the the okay signal given she decided to get herself ready to enjoy this tour to the fullest. This tour both doubled up as a Giantess Tours anniversary as well as an early anniversary present for her and Ken's relationship.

"The boy sure knows the way to a woman's heart..." Sam giggled to herself as she opened the fridge.

Realizing her voice would likely be a bit hoarse if she fully let herself go on this, Sam went to pour herself a glass of milk. It was tricky to hold the carton steady as the tickling on her clitoris had spread out in thirty different directions and was near impossible for her to ignore.

"Oh come on! Just hold out a little longer!" she moaned to her pussy which was growing increasingly wet. "I'll give you all the attention you want later. But let me get hydrated first!"

Sam lifted the glass of milk to her lips before stopping. Scrunching her nose she checked the date on the milk. It was clearly sour.

She had never been one for tracking with tiny details like due dates and it had been harder to keep the milk fresh as Ken had stopped drinking the milk she bought. When she asked him about it he smirked saying that he had found a new favourite type of milk that was easier to get, but didn't go into details where he kept it.

With a sigh, Sam put the glass back down and put the carton back in the fridge. "I guess I'll use my hand for more important things." she smirked to herself as she looked down at her hips.

Sam slowly let her hand glide along her stomach and beneath her wasitband. Her pussy was practically begging her for attention at this point. She had hoped she would make it to the bathroom first but that was looking like it would be impossible now.

She felt her pubic hairs scrape against her fingers in a futile effort to hold them back as her hand traveled along her pubic mound. She had reluctantly asked Ken before if she would have to start shaving when the tours began, but he refused saying her pubic hair added atmosphere and that he personally found it beautiful.

Her finger tip was just about to touch her clitoral hood. Her pussy felt so wet inside at this point that she didn't think it would take much more than a touch for her to orgasm. Before that touch could come however, Sam's attention was drawn away by the sound of a doorbell.

"What lousy timing for a door to door salesman!" Sam fumed marching towards the door. The mood was spoiled but if she sent him away quick enough she could probably recover with the help of the tiny tourists who were working away industriously on her clitoris. When she opened the door however, she was surprised to not see a salesman offering a new water heater or roofing to be done. Instead there stood a young 18 year old girl.

The girl was a slender build though less muscular and toned than Sam's athletic build. She was tan like Sam and with a similar face, but instead of short hair she had long black pigtails kept up with cute accessories. While Sam was standing in a sporty tank top and jeans (which was considered pretty dressed up for her) this girl stood before her in a pretty blue sun dress with white polka dots and high heel shoes.

"SAM!" the young fashionista cried out giving Sam a quick hug, nearly off throwing the tenuous balance she was maintaining with her orgasm. Two soft mounds pushed hard into her chest with the tight hug, the size of which had caught her surprisingly off guard.

"Aren't you happy??" the girl continued. "Your little sister has come to see you before heading off to college!"

Sam was in fact, not happy to see her. It wasn't that she hated her sister. The two were fairly opposite and didn't really have a lot to talk about but she held no resentment against her. But this was really not the best time for an unexpected visit. Today was her anniversary with Ken and she wanted to enjoy it. In fact she was nearly at the point of the highlight of enjoying it when she had been interrupted. In addition to this there was... another reason she didn't want her sister there right now. One that would somehow be even harder to explain.

"Listen, Sarah..." Sam began when a sudden and unignorable sensation came from her clitoris shooting through her entire body. She barely managed to catch herself as her legs tried to give out.

"Sis! Are you okay??" Sarah called out running up to her in concern, but Sam only raised a finger to stop her assuring her she was alright. She was nearing her peak again, and she didn't want anyone to touch her unexpectedly.

"I'm okay..." Sam managed to say. "But listen, I know this is horrible timing and all but I was just about to seriously take a leak before you rung the doorbell and I don't think I can hold it in any longer. Are you able to fend for yourself for a bit??"

"Sis, that's gross..." Sarah replied with a scrunched up nose. "Fine. I won't judge, but I hope you don't talk around your boyfriend like that! It's a miracle enough you got one to begin with! I want to be an auntie some day so you'd better not lose him! Where is he anyways??"

"He's... around..." Sam fought to reply twisting her hips slightly in an effort to relieve the pressure. "He's doing... work stuff right now... I'll tell him you're here afterwards, but now I've gotta go!"

"Eeee..." Sarah marveled looking at Sam. "You look like you're in agony. Just go already before you wet yourself!"

Sarah had barely managed to finish her sentence when Sam ran off towards the upstairs bathroom. The extra distance was a risk, but even if she tried to force herself to remain quiet, she couldn't guarantee she would make no sounds.

She had barely even shut the door before her pants and panties were off and kicked across the room. Sliding across the room she spread her legs to assess the damage.

Her thighs (much like her panties) were completely soaked with her juices. Her lips were wide open and twitching violently. Her clitoris had grown larger than she thought was possible. It rose up like a flagpole almost completely sticking out of her clitoral hood.

"I... can't hold back any longer..." Sam thought to herself before ramming her fingers down into her begging lips below.

The dark crevices we were in was suddenly filled with light. I had just been marveling at the sheer amount of self restraint Sam had been managing when I saw the sky open up with the familiar sight of our bathroom floor.

No sooner had we become bathed in light than two massive tan pillars came crashing down violently around us as Sam plunged her fingers deep into her pussy. Sam was usually a girl who liked to take it slowly, letting her fingers slowly and seductively drag along her skin in an attempt to give us the best possible view. The fact that she was going this fast was just a sign of how hot she must have been feeling.

The entire group gathered around me as we watched in awe as the massive fingers worked tirelessly away completely filling the immense moist cavern beneath us. We could hear her panting and groaning travelling through her body, but she seemed to be a touch quieter than usual.

As the ground beneath us began to tremble I ordered everyone back into the vehicle quickly. Everyone being veterans complied without complaint and soon we had all filed back into the tiny vehicle. Once everyone was in their seats I activated the newest safety feature I had installed. A special bar came around each seat supporting the passengers' heads while also keeping them in place. These special G-Force bars were a safety feature I designed for this specific tour in mind. My own safety seat was specially designed to hold me in place but also give me access to full vehicle controls I could activate with my fingers.

Peering back in the rearview mirrors I noticed the guests excitedly watching the screens on their seats which allowed them to view the exterior from any angle in spite of them not being able to move. The camera angle could be chosen by the controls at their fingertips and would be recorded for purchase up to a month after the tour.

I was about to attempt a maneuver I had never tried before. It was a maneuver I could only have confidence in because of how many of these tours I had given over the years, and how in tune with Sam's body I felt I had become.

"Are you guys all ready for the escape of your lives?" I called back. The passengers all looked up both antsy but eager.

Feeling the rhythm of Sam's body change once again, I put the vehicle into full throttle driving as fast as I could towards the exterior of Sam's clitoris. Once we had exited the hood, I pulled the vehicle sideways and began driving up the side of Sam's clitoris, a feat that could only be achieved at such speeds. We continued driving further and further along until finally we drove off the edge and began to plunge down below.

People on board screamed, but it was the screams of a thrill park not of terror as they had come to trust my driving over the years. In front of us we could see the massive gaping opening of Sam's vagina twitching before us as Sam had removed her fingers and begun focusing more on her clitoris. Then, just as we were over the widest part of Sam's gaping cavern, the vehicle started to shake as a strong wind came towards us. The wind was followed by a torrent of thick liquids as our vehicle as shot up miles into the air by Sam's orgasmic squirting.

From our new height we could see Sam lying on her back, with her smooth muscular legs spread apart. It was an incredibly erotic angle and I heard a lot of screenshot buttons being activated as guests madly attempted to remember this angle forever.

As the vehicle began to descend again I activated the parachute which let us casually fall to the ground.

Sam still lay on the ground gasping and giggling to herself as we drove out of the bathroom. I made sure to take the scenic route around her body on the way out before making my way back to a garage box I had kept nearby just in case. Once the vehicle was safely secured I made my way outside before growing myself to full size and carrying the box out back to where I kept the vehicle parked. Once I grew the vehicle back to full size the guests all disembarked one by one laughing and chatting while carrying bags full of precum and other souvenirs they had managed to scrape from the inside of Sam's clitoral hood.

I had just waved goodbye to the last of the guests who had all asked when the next tour would be. As I turned around I noticed Sam standing out of their sight sheepishly.

"Hey! Was it fun?" I asked her approaching her and rubbing her arm. "It was an amazing sight for us and I was really surprised at how long you manged to hold out! The guests were really happy!"

"My sister's here..." Sam explained bluntly cutting me from my thoughts.

"Oh..." I replied embarrassed. "umm... we didn't put you in an awkward situation did we?"

Sam shook her head. "It's not that but.... Can we talk for a bit... somewhere where she won't see us??"

I couldn't help but feel nervous at how awkward Sam was looking right now, but after careful thought I nodded my head. "I think I know of a place we can hide."

"Are you sure this place is secretive enough???" Sam asked me nervously for the 20th time.

"Don't worry. I've checked this place out myself and we're practically invisible!" I replied confidently.

We were currently sitting in the vehicle which was a little over an inch in length. The vehicle itself was sitting in a pill box surrounded by long white oddly shaped pills. I had noticed a month ago when Sam first bought these pills that they looked eerily similar to what my vehicle looked like in submarine mode. While we were at a size that we could easily be seen at, this camouflaging technique left us essentially invisible to anyone who knew about shrinking technology. To anyone who didn't well... it was the last place they would ever look.

Seeing Sam's nervous expression I realized that it might not just be our hiding spot. This was also the first time Sam had ever experienced the shrink ray. As she was always our destination and she enjoyed that so much, I had never had an opportunity to let her experience the micro world before.

"It's perfectly safe you know." I assured her. "We're tinier now, but our bodies become more resilient the smaller we shrink. As hard as it may be to believe, we're actually harder to kill now than we would be at full size. So what is it you wanted to talk about?"

Sam took another nervous look around before letting out a sigh of defeat.

"I... I haven't told my family about what we do..." she reluctantly explained.

A part of me felt a little hurt. I mean logically it made sense. Telling your family that "My boyfriend earns us money to live off of by taking hundreds of people to explore every nook and cranny of my body while I pretend to be unaware of it all." isn't really the kind of thing you would bring up at the dinner table... but it made me wonder something worrisome.

"Are... are you ashamed of this?" I asked nervously. I had only kept the tours going under the assumption that Sam was enjoying it. But if she was forcing herself to do this for my sake then...

Sam however shook her head in protest. "It's not that I'm ashamed... per say..." she replied. "It's... it's just something else..."

---------------------------------------------------------------------------------------------------------

Sarah brushed out her skirt as she swung her legs idly off the side of the couch. "Where are they?" she thought to herself getting frustrated with every passing minute.

Sarah had wanted to meet Sam's boyfriend for ages now, but had always lived too far away to have the chance. Though she would never admit it, she really respected her sister and looked up to her. She was at first ecstatic that she had met a guy who seemed to appreciate her for who she was, but at the same time, Sarah wanted to ensure it was a guy who was worthy of her.

Sarah looked around at the furniture in the house. The guy apparently made a decent amount of money for them to live like this, but she was still unsure. The moment she first doubted was when Sam told her she was giving up her athletic dreams to live and be supported by this guy.

For as long as she had known Sam, she had always been obsessed with sports. While Sarah really didn't know the first thing about sports, she always thought her big sister looked really cool while beating everyone at them. If this guy had forced Sam to give up her dreams to serve him and make him sandwiches and such! ....no wait... that couldn't be the case... There was no way Sam even knew how to make a sandwich....

Sarah jumped to her feet with a groan. She was getting too frustrated waiting. "SAAAM! WHERE ARE YOU??" she called out walking into the kitchen.

Sitting on the counter top she noticed a tall untouched glass of milk. This was clearly Sam's... the girl practically lived on milk, though it never seemed to help her breasts grow any.

Giving a slight smirk, Sarah had a devious idea.

"SAAAAM! IF YOU DON'T COME SOON! I'M GONNA DRINK ALL YOUR MILK!!!!" she called out raising the glass off the countertop.

Silence...

"I'M REALLY GONNA DOOOO IT!" she cried out again.

Again... Silence...

"FINE!" she shouted before chugging the entire glass down as fast as she could.

About three seconds after drinking the milk she was filled with sudden regrets... it smelt HORRIBLE and tasted disgusting. She felt her entire stomach lurch as her bowels attempted to release all contents....

"Oh no..." she thought to herself suddenly having flashbacks to all the times she had been forced to eat overdue foods due to Sam's negligence.

As if on reflex, she ran full speed towards the washroom she had seen her sister go to.

Our conversation was interrupted as a loud bang was heard of the bathroom door being forced open and the room was full of light. We could hear panicked noises of clothes being hastily pulled off followed by wet sloppy disgusting noises of someone with unbearable diarrhea. The noises continued for a worrisome amount of time.

"Is... is your sister okay?" I whispered to Sam even though at our size we could shout at the top of our lungs and not be heard. Sam simply groaned burying her face into her hand.

"I bet she drank my milk..." she replied, unaware of my slight squirm at her mention 'my milk.'

"The stuff was like a month overdue... I'm just glad it didn't kill her. The girl always has been a touch rash."

"Huh..." I thought to myself feeling fairly thankful that the air inside the vehicle was completely filtered.

----------------------------------------------------------------------------------------------------------

Sarah finally finished relieving and wiping herself but she still felt horrible. As she washed her hands in the sink she noticed a medicine cabinet in front of her.

"I wonder if sis has any stomach medicine..." she thought to herself opening the cabinet. As she scanned the shelf she noticed one box in particular for upset stomachs and diarrhea. As she read the details she let out a groan.

"Seriously sis??" she whined. "You're allowed to get normal meds at least once in your life!"

----------------------------------------------------------------------------------------------------------

Our world shook as the box of pills we were in was lifted.

"OH SHIT OH SHIT OH SHIT OH SHIT!" Sam cried out clinging to me. I couldn't help but be thankful for the sudden affection, but it would probably be best to ease my girlfriend's worries.

"Don't worry..." I replied. "There are like 200 pills inside this box. It would take a miracle for her to take ours by mistake!"

A Miracle Happened...

As two large fingers gripped our vehicle on either side we were lifted into the air where I got my first good look at Sam's sister's face.

Her big brown eyes with thick eyelashes squinted at us as if she were looking at something truly disgusting. She wore more makeup than Sam and her hair was longer. While Sam was an athletic tomboy, her sister could clearly be described as a girly girl. With a jostle her hand lowered and we were now in line with her massive mouth. Red lips covered in a pinkish lip gloss surrounded the massive cavern of dangerous teeth and tongue.

"Don't worry!" I desperately comforted Sam. "I've already been through a mouth before! I know how to navigate us safely I promise!"

Much to my surprise however, the hand did not approach the mouth. It continued south past her chin, her throat, some... surprisingly large breasts, and down around her stomach. As we traveled I noticed the blue fabric with white polka dots was moving as she seemed to be adjusting her dress.

"Which pill box did you get in?" Sam asked me nervously. I simply shrugged in response.

"I don't know." I replied. "I like never get sick so I've never taken medicine before. I just went into the box of pills that look identical to the vehicle."

"Oh crap..." Sam groaned, and I was about to understand why...

---------------------------------------------------------------------------------------------------------

"Why can she never just get pills you swallow??" Sarah groaned as she pulled down her panties with one hand and pulled up her skirt with the other.

Ever since Sam had read an article as a kid saying that suppository pills were more effective, she became obsessed with only taking them. They felt gross to put in, but she claimed that finding the strength to overcome adversity was what made you strong enough to get better.

"Ugh. Next time I'm bringing medicine on me..." Sarah groaned as she attempted to position the pill above her anus.

----------------------------------------------------------------------------------------------------------

The light all around us turned blue as we were pulled underneath the skirt. Seeing her young shapely butt cheeks before us it became obvious that Sam's sister was not as athletic as Sam was, but that brought a unique form of attractiveness to it.

We were slid between her thick butt cheeks and completely surrounded as Sam's sister clumsily attempted to find her anus by feeling. Finally on the third try the nose of the vehicle lined up perfectly with her puckered hole and we began to get pushed in.

The walls of the vehicle groaned slightly as we were pressed against the tight hole, but the exitway eventually gave way to us and let us slide in.

----------------------------------------------------------------------------------------------------------

Sarah flinched slightly as the pill finally slid into her butthole. She had always hated the sensation of something sliding into her butt and this one felt incredibly awkward.

Reaching down she pulled up her panties and made her way out of the washroom. She ended up clenching her butt cheeks as she walked as it felt like the pill was attempting to push its way back out again.

"This medicine had better work..." she groaned before lying back on the couch in pain.

"Come on Ken! You've got to get us out of here!" Sam begged me on as I continued revving the engines. "I don't want to be trapped in my sister's butt! And I don't know how much longer Sarah's planning to stay here for!"

After one last ditch effort I took my foot off the gas and shook my head.

"Sorry Sam, we aren't getting out that way." I replied. "I don't know what it is with your family and tight butts, but there is no way we have enough power to push through that hole at our size, and trying any more will likely break the vehicle again."

"Then we should shrink further so we can be more durable and get out!" Sam cried out again in protest. Again I shook my head.

"There are three rules of shrinkology you need to adhere to." I replied seriously.

"Shrinkology?" Sam interjected.

"HUSH!" I shot back. "You can't pressure me to come up with a name for a science on the fly and expect it to be good!

Anyways, there are three big rules that cannot be broken when it comes to shrinking.

1. An object that shrinks will grow in strength, speed, and durability proportionate to the size of which they shrunk.

1. An object cannot be shrunk smaller than a molecule, nor can it be grown larger than its original size.

1. An object once shrunk must return to its original size before it can shrink to a new size."

Sam leaned back in defeat realizing what this meant. "So that means the only option is to wait until she takes a dump again..." she groaned.

"I'd rather not do that..." I replied remembering my first trip through Sam's digestive system. "First of all, while her bowels are pretty empty right now, you really don't want to deal with the pressure of them being full. Secondly we don't know how long she's going to stay here for. Third of all, I REALLY don't want to navigate the sewers in the off chance we get flushed..."

"So then what do we do??" Sam replied half frustrated and half desperate. This time it was my turn to smile.

"I have a plan." I replied. "As of now it is untested, but it's an emergency escape plan I've had for quite a while. But to get it to work we'll have to get to her stomach!"

With an apprehensive nod from Sam I turned the engines of the vehicle back on and made our way through the tunnel before us. I was a good deal larger than when I went through Sam's body which made this to be a narrower squeeze. Chances were unlikely that I would be able to turn around if we got stuck so it was probably best we kept going.

While I felt sorry for her, Sarah's toilet troubles had made for a thankfully very clean intestinal track. There were still splotches of moist brown sludge on the walls here and there, but Sarah's bowels hadn't been this empty, there would have been no way for us to make this journey without some heavy duty drilling equipment... a note for future to the vehicle. upgrades.

The ridges of Sarah's bowels made for a hilly drive, but my vehicle was meant for literally all terrains so we managed to make our way through. The effects of the bad milk had obviously not passed yet as the tunnel around us occasionally vibrated and groaned.

----------------------------------------------------------------------------------------------------------

"Ugh! Come on! Work faster you stupid medicine!" Sarah groaned gripping her stomach as it felt like her entire intestinal track was groaning under the stress. It felt like her insides were alive and in pain... like there were ants crawling around inside her.

"Sam! I'm never gonna trust you again with food as long as I live I swear it!" Sarah promised, though the truth was that this was far from the first time she had said this...

----------------------------------------------------------------------------------------------------------

We had made quick progress through the bowels and large intestine and now made our way through Sarah's small intestine. When I had gone through Sam's body, I went WITH the flow of her digestive track. Going against the flow made me realize just how strong the current actually was, and I was thankful I had equipped the vehicle with extra powerful fans while in sub mode.

As my hands shook trying to hold the ship steady, I wondered how it would look if a doctor saw us now. "How did a suppository pill end up undissolved halfway up your small intestines??" he'd probably say.

Turning to my right I noticed Sam staring wide eyed at our surroundings. Admittedly the brownish red tunnels coated in tiny tentacles desperately attempting to suck up any nutrients was a unique sight for anyone to see. With the new and improved flood lights on the vehicle, Sam was able to see this clearer than ever.

"It's a unique feeling isn't it?" I asked Sam pulling her from her thoughts.

"Ah! No! I was just thinking it looks a lot different than in that kid's show I watched when I was younger."

I gave a chuckle at the innocent remark as Sam peered out the window again. For me I had spent the past few years going through every part of her body countless times, but for her this was all new. It was interesting to see the giantess' reactions to going through another person's body.

We maneuvered the long, nearly endless tunnels of Sarah's 'small' intestine for what felt like an hour before we finally reached our destination. As I saw the small puckered hole in the distance I sped us ahead full throttle. Thankfully the milk had seemed to have done quite a fair bit of damage and the puckered sphincter was loose enough for us to slide through with little difficulty. As we did we found ourselves in a massive cavern falling a good inch until we landed on top of a mountain of slightly chewed crackers, eggs, and other foods surrounded by a white lake of curdled milk.

"We're here..." I called out to Sam giving her a chance to take in the surroundings.

Sam was silent. Anyone in her position would be. We now sat in a massive cave easily twice the size of our house. Around us was food which, for Sarah, had been chewed down enough for her to swallow, yet for us was large enough for us to drive over. While the acids of Sarah's stomach had already begun to work away at was probably the remains of her lunch, you could still make out a fair amount of what it all originally was. We could probably have fed an entire country on the contents of her stomach alone at this size. There were days when it made me question if there weren't more helpful things I could use shrinking technology for.

The walls around us quivered and wailed as Sarah's stomach churned and complained about the overdue milk which now filled her. Having snapped back to reality, Sam now turned back to me.

"What is this emergency escape plan?" she asked eagerly hoping to get out as soon as possible. To that I gave a simple smile.

"Inside the glove box in front of you you'll see an envelope and cardboard box. I want you to hand them to me being REALLY careful with the cardboard box."

Sam proceeded to hand me the contents I was looking for and then watched curiously as I turned towards the door.

"You... may want to hold your breath for this part..." I warned before opening the door. The airtight vehicle was now filled with the smells of half digested food and curdled milk. Thankfully Sarah had appeared to have eaten some oranges with her lunch which helped combat the smell a bit, but it was quite a lot to take all in one go.

Opening the envelope, I emptied the contents in my hand and then threw them out the door while hitting them with the shrink ray.

"HEY WHAT ARE YOU DO-" Sam began to shout, but I knew what I was doing.

The contents of the envelope grew to full size as large lumpy candies of various sizes fell into the stomach acid, some of which were larger than the vehicle's tires! Once they landed into the acid, some of them began to burst shooting against the walls of the stomach which quivered and groaned all the more at the sudden unexpected sensation.

"What are those?" Sam asked in shock.

"They're poprocks!" I replied simply before gingerly holding the box. "If we were to grow ourselves back to full size within Sarah's stomach, she would explode, but as long as what we grow is smaller than she is we can return it to normal size without any damage being done."

Removing the lid of the box, I next carefully removed a bag of clear liquid from the box. The bag itself was incredibly thin which was why it needed to be handled with such care.

holding the bag in both hands I threw it as far as I could underhanded into Sarah's stomach before shooting it with the shrink ray and slamming the vehicle door back shut. The bag grew back to full size pushing us and the contents of Sarah's stomach against the side. It had become a much tighter fit inside, but that wouldn't last for long.

"What was that!?!?!" Sam replied in surprise.

"Carbonated Water." I replied again matter of factly. "An entire can's worth. It shouldn't take long for the bag to burst given the weakness of the plastic."

"Wait then..." Sam pondered trying to make sense of what I was saying. "So your entire emergency escape plan is to mix carbonated water and poprocks in my sister's stomach??"

"Yep!" I replied once again matter of factly. "I got the idea while reading an article on stomach x-rays."

Before Sam could protest any further, the bag finally burst flooding the entire inside of the massive cavern with clear fizzy liquid. When the carbonated water hit the poprocks the effects were immediate. The world around us churned and bubbled as the walls of the already massive cavern extended much further, to the point that any wrinkles were stretched out.

"Ah! There's one more thing we need to do before this gets started." I replied to Sam flicking a switch. Immediately our seats held us in place in G-Force safety mode. This would NOT be a smooth ride!

Sarah had just begun finding a happy medium with the pain in her stomach when a new sensation in her stomach. It felt almost like fireworks were erupting inside her as sharp stinging sensations were felt against the walls of her stomach. Before she could comment on this sensation though she suddenly felt incredibly full, as if an entire stomach's worth of food had immediately teleported inside her.

Curious, she found herself poking her slightly distended belly, which turned out to be a mistake.

It felt as if a ton of liquid had begun sloshing around inside her followed by an incredibly amount of gas. Forgetting her manners, Sarah watched in horror as her belly began to grow rapidly before her. She may not have been as athletic as Sam was but she never considered herself chubby before. But her stomach continued its relentless expanding as the pressure within her continued to rise.

"What was in that medicine!?" Sarah attempted to say, but in doing so she had opened up a path for the pressure inside her to travel.

*BRAAAAAAAAAAPP*" a massive burp came from her as her stomach still continued to grow. It was starting to look like she had become pregnant!

Sarah tried to protest but every time she opened her mouth, louder and louder burps came out. Finally Sarah attempted to scream, but instead the loudest burp yet followed. It was strong enough to relieve some of the tension in her belly, but it also felt like something large was climbing up her throat.

"What is-" she began to say as she felt something solid enter her mouth, but instead another burp came blowing whatever it was far away. In defeat, Sarah plopped back down onto the couch leaning back so this could just take its course, unaware of the small item that had fallen down her cleavage.

----------------------------------------------------------------------------------------------------------

"HOLD ON!" I cried to Sam as a massive updraft shot us into the sky. The bubbling ocean below up traveled further and further away as we were forcefully shot up Sarah's esophagus.

We traveled up her esophagus at high speeds, but much to my concern, we were losing our velocity. Sure enough, as we entered Sarah's mouth we flew skidded along her tongue before crashing into the backs of her bottom teeth.

"Are.. are you okay?" I asked Sam as I tried to regain my own senses.

"Uhhhhh... I think so..." Sam groaned. "But what on earth do we do know?"

My horrors were once again realized as the vehicle was carelessly lifted up by Sarah's mighty tongue as she attempted to figure out what had just landed in her mouth. Best case scenario she would spit us out but it would be tricky to escape. Worst case scenario she would swallow us again meaning we'd have to redo the whole trip the proper way this time.

Light crept into the massive cave as Sarah's teeth and lips parted. It seemed like she was about to say something, but before before she could we were blasted forward by another powerful burp.

The vehicle passed Sarah's teeth and lips before falling down along her chin making a beeline for her cleavage.

"Thank goodness she looks like a D cup.." I caught myself saying out loud. An angry sidelong glare from Sam alerted me I should explain myself.

"There's a good chance we can slow our descent on her breasts." I explained. "Then we can just wait till she lies down and drive out."

"Umm... there's something you should know about my sister..." Sam replied, but at this point we had already passed her neck line and made a beeline for her bra. I had braced myself for the change in direction with the slope but then was shocked when I felt... nothing???

Did I miss and hit her cleavage instead? But that was impossible at this size! It was like missing a mountain with a paper airplane!

Finally we stopped with a sudden jolt as we had collided with a wall of some sorts. Looking out the window I realized what had happened.

Sarah was a girl who padded her chest.... she padded her chest quite a bit. In actuality she was most likely smaller than her sister, but with the help of two bras and several pads she managed to pull off the look of a D cup.

Consequently what had stopped our descent was not the gentle sloping of her breasts as I had expected, but her nipple which had somehow become quite hard.

Unfortunately, while her nipple was hard, the space within her oversized bra was larger than expected. As such our vehicle now balanced delicately on her nipple threatening to fall over at even the slightest nudge.

----------------------------------------------------------------------------------------------------------

Sarah gave one last light burp. It seemed like the medicine had run its course. Surprisingly she did feel better though she never attempted to trust either the food or the medicine his sister had ever again.

Her stomach feeling better Sarah noticed a new sensation. An itch on her nipple. She had always been incredibly sensitive to stimulation and so this itch could prove quite disastrous to her.

Looking around she saw that her sister and boyfriend were still nowhere to be found. She could probably enjoy herself for a bit though she would have to be careful not to undo the balance of her bras.

Walking into the bathroom she slid her hand carefully down the front of her dress and under her bra to her budding nipple. She was hard... very very hard. The touch of her fingers felt amazing and she couldn't help but let out a slight moan as she rubbed them over her aereola.

As she adjusted her grip a bit better, the bottom part of her bra lifted lightly causing something to fall out. She was caught off guard as she felt something fall down her torso, but its direction was somehow making her hotter.

----------------------------------------------------------------------------------------------------------

A light burp from Sarah was all it took. The vehicle lurched over the edge before sending us past the point of no return. The large nipple twitched slightly as I screeched the tires of the vehicle giving every attempt to hold on to our precarious cliff but it was not enough. We tumbled down the gentle slope only to be saved by Sarah's underwire.

"Well that was too close for comfort..." I marveled to Sam. Our relief was short lived however as the bra was soon filled with light. Two massive fingers we had not seen since our entry into Sarah's body made their return, but this time their target wasn't us.

With the gentle skill of an artisan the fingers lightly gripped and twisted the massive nipple above us as a light groan could be heard.

"Ugh! I did not need to see this side of my sister today..." Sam groaned, but I had a bigger worry on my mind.

As the fingers became more vigorous, the bra beneath us pulled farther and farther away from Sarah's body. Finally the gap was large enough that the vehicle lurched and began to fall again.

"HANG ON!" I cried out as the vehicle made its way down Sarah's body. In desperation I used every ounce of my concentration to attempt to steer the plummeting vehicle and keep us from ending up a wreck.

"Doesn't this thing have parachutes?" Sam cried out, but I simply shook my head.

"There's not enough room under your sister's dress. Our best bet is to try and drive it out. Maybe your sister's pubic hair will be enough to slow us down!"

"SARAH'S P-P-PUBIC HAIR!?!??!" Sam cried out but it was too late for complaints.

My fingers moved like a pro gamer as I used the G-Force protection control board to attempt to steer us along the unfamiliar body. If this was Sam's body I could make the trip blind folded as I had every curve, crevice, ab, and corner of her body memorized. Sarah's body however was fairly different than her sister's. Far softer and more curvy.

As we made our way past her belly button, her belly was still slightly distended from our earlier experiment which thankfully pushed our vehicle in line with the crease of her hip. We followed the crease of her hip along the bone under her panties where I turned on the headlights to find...

No hair....

Sarah was as bald as a baby's bottom.

I guess the thought that Sarah might have shaved should have crossed my mind given her attention to fashion, but I had gotten so used to Sam's body that I had forgotten that anyone would do such a thing.

Our ship shot past the silky smooth skin like a rocket before shooting into the bottom of her panties. The elastic force of our impact thankfully kept us from getting a lethal case of whiplash but also shot us back vertically with an equal amount of force. It was at this point we discovered that Sarah was a good deal aroused. While her vaginal lips were far smaller than her older sister's, they were wide enough for us to get shot up into with only the sound of Sarah's cry to be heard.

Sarah let out a cry of pleasure as she felt something hit against her sensitive pussy lips. She was already wet down there from her working on her nipple but this was irresistible.

"Ugh... and in my sister's house..." she moaned to herself. "This is... this is so dirty... I can't believe I'm doing this... but at this point I can't help it!"

pulling up her dress to reveal her panties, she slid her hand under the waistband and along her bald pubic mound. Once she had slid them over her twitching clitoris she proceeded to push her well manicured slender fingers deep inside her unaware of the passengers she was taking with her.

"Ugh! Sam!" she panted between pumps with her fingers. "This is my vengeance for abandoning me today! You're gonna have your little sister's womanly juices all over your boyfriend's bathroom floor!"

As she continued to stroke herself and rub her nipple simultaneously, she felt as if her vagina was on fire. She had never been able to feel sensations this deep with just her fingers before. Maybe she was coming across a new fetish!"

----------------------------------------------------------------------------------------------------------

"I repeat... this is NOT a side I wanted to see of my little sister..." Sam grumbled from her seat. We sat back watching as two massive fingers continued to pound away at our only exit.

I had thankfully managed to drive us deep enough that Sarah's fingers couldn't reach us, but so help me the girl had long fingers. We were practically parked against her cervix to avoid being crushed. Her nails were covered in pink nail polish with gold glitter tips which had begun to stick to the walls. It made me wonder how she was going to react when she found out her fancy manicure was being ruined by this.

"Knowing she's related to you... our only option is probably just to wait until she's done..." I replied trying to lighten the mood a bit.

"Mmm." was the only grunt I got in response.

Turning to Sam I saw her looking up frustrated at the massive fingers which blocked our way. Sarah's love tunnel was surprisingly different from her sister's which made me wonder how much they varied from person to person.

"Say Sam?" I asked apprehensively. Today was supposed to be our anniversary, so I felt horrible that she got dragged on this crazy adventure.

"Hmm?" Sam replied disinterested.

"You know how we have our valentines day special for couples right? The one where we let them all have sex in your vagina while you orgasm?"

"Mmm" Sam replied still equally frustrated and disinterested.

I took a deep breath before suggesting the next part.

"Did you ever.... Did you ever want to try it yourself?" I asked nervously.

Sam turned towards me with a look of disbelief on her face.

"Did you seriously just ask me if I wanted to have sex with my boyfriend in my little sister's pussy??" she cried out.

I flinched defensively blushing at what a ludicrous thing I had suggested.

"Look, I know it was a bad suggestion." I defended. "I just thought this might be the only time you get to try it so I thought I would offer!"

Sam leaned back in her chair looking at the pulsating red walls outside.

"It's a horrible idea..." she replied putting the final nail in my coffin. "But... at the same time... I will admit, I've been horny for the past hour and desperately need someone to do me right now..."

I quickly turned to Sam who had leaned towards me with glossed over eyes.

"Hey Ken..." she asked putting her hands on her thighs. "Help your giantess out a bit?"

This was all the encouragement I needed. Pulling Sam into an embrace, I began kissing her vigorously as I ran my hands along her body. Sam in turn grabbed at my pants far more passionately and began stripping me down.

I gently removed her clothes noticing that her panties were already completely soaked through and then began fondling her breasts as I was kissing her. At one point I attempted to pull away, but she grabbed my by the head pulling me back into even deeper kisses.

My girl was... VERY turned on.

Now that we were both naked, we made our way outside of the vehicle where we were instantly bombarded by waves of hormones from Sarah's vaginal fluids. The aphrodisiac effects of this was something I was already familiar with, but for Sam this was her first time, and she was far from immune to it.

She began kissing me all over as we were thrown against the soft wet walls of Sarah's vagina by her internal convulsions. Sarah's wet liquids covered us lubricating us and making us all the more passionate.

No longer able to hold back, I began having sex with Sam sliding easily into her pussy with the mix of her and Sarah's juices. We moved to the rhythm of Sarah's fingers and the movements of her vaginal walls turning us on harder than we had ever been before.

It was an amazing set of intercourse and no sooner had we finished in each other, than Sarah orgasmed blasting us and the vehicle out of her young pussy along with her juices.

We found ourselves on the tiled floor of our bathroom between Sarah's legs sitting in a puddle of her womanly juices. Above us was the twitching lips we had fallen from and in front of us was the massive canyon of her butt cheeks spread apart slightly as if asking us if we wanted round two.

Sam and I both refused the invitation, and instead made our way back to the vehicle leaving Sarah to lie on our bathroom floor panting in private.

----------------------------------------------------------------------------------------------------------

"I'M GONNA MISS YOU SO MUCH SIS!" Sarah cried out giving her sister a giant hug.

After we had taken a quick shower, we returned to normal size and met up with Sarah who had become surprisingly bashful. We apologized for our absence, I said it was my fault as something work related came up I needed Sam's help for, and we proceeded with our visit.

Sam was a little awkward next to her sister after having seen so many new sides of her, but having not known what their relationship was like normally it could have just been how they normally were.

Now we were saying goodbye to Sarah, wishing her luck in college and telling her she could stop by any time (but maybe call first next time.)

Sarah walked away leaving Sam and I alone in the house once again.

"You know... if you ever want to tell your family I'm willing to take the blame for everything..." I replied to Sam as she shut the door.

"That's okay.." Sam replied with a satisfied smile. "I like it better this way."

Wrapping her arms around me she gave me an incredibly long and deep kiss before pulling back and admiring me with passionate eyes.

"Your tiny adventures are MY private fun time and I don't want to share you with anyone else!"

I involuntarily blushed as Sam revealed her unexpectedly possessive behaviour.

"Umm, so... how did it feel being the shrunk instead of the giantess for a change?" I stammered in an attempt to change the subject.

Sam looked at me with an unimpressed blank stare. Reaching behind me she grabbed the shrinking device from my pocket and proceeded to shrink me to close to a mm in size. I looked up to find myself on the underside of her fingernail being brought down at high speeds along her body. The finger proceeded to take me along under her waist band and through her pubic hair until it stopped holding me directly in front of her already erect clitoris.

(Good gracious girl! You've already orgasmed 3 times today!) I thought to myself admiring my girlfriend's stamina when my cell phone rang.

"Sam?" I asked apprehensively as a shy voice responded.

"I didn't get to enjoy the tour today because Sarah interrupted." Sam explained. "I want you to make it up to me now."

With a mischevious smile I jumped off of Sam's fingernail and proceeded to climb under her clitoral hood. She had made sure I was larger than I had been during the tour so it was a tight fit, but her twitching and growing clitoris suggested she did enjoy it.

"Hey Ken?" she asked sheepishly over the phone. "I don't want you getting aroused in any other girl's vagina except for mine from now on okay?"

Again, my heart beating faster from Sam's unexpected bashful side, I didn't even need to answer. I proceeded instead to rub my whole body against her twitching clitoris which was met by sounds of groaning from her from above.

I love my girlfriend so much...
