Selina flexed her muscles, soaking up my presence in her asshole. Her body vibrated and hummed while she rolled her eyes back. Feeling me slide into her internal organs felt amazing. Each inch I slid induced a kind of orgasmic spasm. Her body was in bliss without even masturbating. Once I was fully submerged, she grasped her pillow and focused on the tiny feelings caused by my exploration inside her. She couldn’t help but smile knowing that I was traveling up her bowels. 

“That was hot.” I said thinking about how her ass just ate me alive. 

Her walls were pulsating around me as I started my journey deeper. Katie was in there somewhere and I had to find her. I began checking in all the crevices and folds for my 6-inch girlfriend. Selina’s intestines were quite clean, other than some splotches of fecal matter and mucus. I checked ridge over ridge searching everywhere in her large intestine. My body became covered in her internal goo. Eventually, I turned a tight corner and spotted a small white ass. I grabbed her with both hands as she yelped in shock. 

“Gotcha!” I cheered. 

I rolled over onto my back and held her above my face as we laughed. Then suddenly, I noticed her body growing in my bare hands. Her height and weight began to increase very quickly. It soon felt like I was holding a child above my head. But she kept growing to the point where I couldn’t hold her up anymore. My arms started to shake and then her ass came crashing down onto my face. She was about half my size at this point. She just kept growing, her small ass got bigger, eventually smothering my face. It didn’t stop there, I soon realized that while she was growing, I was shrinking. So her tiny ass soon expanded to be bigger than my entire body. It was magnificent. Her cheeks kept stretching out until they were stronger than me and I soon became their prisoner. By the time I stopped, I figured I was about one inch compared to Katie’s new size.

“That was weird. We both changed sizes at the same time.” She said shaking off the strange sensation of growing. 

Her cheeks closed in around me as she moved around searching for me. I stayed perfectly still while she failed to detect where I was. I was now the hider and she the seeker. Her anus was only an arm’s reach away and it would make for the victory hiding spot. 

“Where’d you go, Max? You were right under my ass, did you keep shrinking?” She asked struggling to maneuver around while in her mom’s tight bowels. 

I made my leap of faith and plunged headfirst into her slit. I couldn’t help but smirk in the realization of this being the second asshole that I’ve breached in under 10 minutes. However, I only made it halfway before Katie squeezed her sphincter around my tiny waist. 

“Oh no you don’t! I know what you’re trying to do. You can’t win that easily!” She said revealing her competitive side. 

Her tight skin contracted around me while her body squirmed about. She tried to hold me but I was covered with intestinal mucus so I managed to slip inside. She moaned while also shoving a finger in after me. Her nail grazed my foot as she rammed it deeper. I had to quickly crawl deeper to escape. As I did that, Katie was trying to anal birth me. Her bowel’s muscles contracted and squeezed my sides, trying to force me out. Unfortunately for her, I was too quick and could out crawl her bowel movement. 

“Ughh, you’re a fast little pervert aren’t you. I guess if you’re going up there, you’re going to go all the way.” Katie said annoyed with losing but also happy with her new intestine prisoner. 

I was happy with my little victory and ass-inception hiding spot. I relaxed in her warm internal folds as they reversed their direction. She was now sucking me in rather than pushing me out. I was okay with this. I just closed my eyes and soaked in the blissful massage from her organs. My mind drifted into a deep sleep with a pretty bizarre dream.

Katie and I were both a centimeter tall as we crawled up Selina’s intestines. She was ahead of me as I chased her. We were playing hide and seek, or tag rather, inside Selina’s ass. My girlfriend traveled in front of me, reaching quite deep into the digestive tract. Her butt jiggled while I starred with the desire to pounce on it. Just as I was catching up, she turned a tight squishy corner and then disappeared. There was a tight sphincter with a white glowing portal-like center. I squeezed myself through which then teleported me into Selina’s throat. At the end of the long wet tunnel was Katie waving at me. She giggled and then disappeared down another pathway. I traveled up Selina’s esophagus to the roof of her mouth. Katie wasn’t there so I chose the path into her nose canal. The passageway got tighter and a lot stickier. There were globs of snot that I had to force my way through. The warm goo felt pretty nice on my skin though. The tunnel then split into many different directions and crevices. I followed one that eventually opened up with little nose hairs here and there. Their mucus-covered fibers caressed my back as I got closer to the exit.

“Follow me!” Katie said appearing at the nostril's entrance. 

I crawled out and found myself on Selina’s massive cheek. Katie grabbed my hand and led me around to the giantess’ ear. The skin stretched outwards and made some really cool designs. Looking at her ear up close was pretty cool, the skin had many bumps, crevices, and neat designs. Katie pulled me down inside where the tunnel got narrower. We began crawling and then reached her eardrum. 

“Watch this... Echo…” Katie said as a faint echo soon followed. 

I was fascinated by how the thin fabric-like texture vibrated from the sound waves. It was like a ripple effect from the center of the drum. Katie smiled as she placed her hand on the sheet. 

“Uhhhh…” Katie released a deep throat moan, “If we fucked right now, my mom would be forced to listen to the entire thing.”

She then giggled as I got a very hard unexpected boner. Another white portal-like glow then appeared under Katie’s hand as she opened it up on the fabric.

“This leads to her other ear. I bet my mom would love to hear us from both sides.” She said seductively. 

My hormones were all over the idea. Katie crawled halfway through the portal, leaving her massive ass still on my side. I grabbed her hips while she presented me with her anus and pussy. I decided to take the dirt road. I mounted her and slid my hard dick into her tight anus. The skin parted as I felt the warmth of her internal flesh. Selina noticed her daughter in her ear then decided to join in with the fun. 

“Katie, how about a little pleasure for mom?” The giantess asked. 

Katie was then picked out of her ear as she was taken away from me. Not long after, I saw Katie’s face peering into the ear. She had grown and was now massive. She put her nose up the hole and sorted me up. The air current sent me deep into her nasal canal. I crawled back to where I entered and saw Selina’s ginormous ass and pussy. 

“Eat my ass like a good little girl.” She demanded while moaning. 

Katie did just that. She used her tiny tongue and massaged the woman’s anus. I had a front-row seat and it was spectacular. My dick pulsated, begging for release. I shifted my body and found a tight crevice filled with snot. The warm mucus made for a great lube as I thrust into it. Her nose hairs tickled my body and felt neat against my bare skin. The harder I pounded, the more Katie moaned and vibrated my surroundings. Everything had built up pressure and I was about to explode. I could feel my dick swelling in the tight mushy booger crevice. My girlfriend then did me one last favor. She spread Selina’s cheeks and showed me her gaping asshole. Looking into it was the final spark that erupted my load. My body tightened and tickled Katie’s nose hairs. She then winced and sneezed into her mom’s ass. My tingling body got sent flying directly into the black hole. I landed in her soft flesh and then opened my eyes. 

“That was a weird dream.” I said to myself. 

I was still inside Katie’s bowels except now I was pretty deep into her small intestines. The soft flesh surrounded me, hugging me from all sides. My dick indented the bottom wall as I laid in my own semen. It was a pretty great finish so I didn’t really care. I just closed my eyes again and smiled, savoring the warmth of being inside my girlfriend’s digestive tract.
