Becca was waiting patiently by the pool in her backyard. The 20-year old woman was expecting her 21-year old brother to pull up on the drive way in the front very soon. She wanted revenge. For her birthday last week he had managed to sneak some weird serum into her drink. She had been lamenting over how old she felt so naturally he had given her something to temporarily age her up to 70 years old. He thought it was funny to do at her birthday party, she did not. Luckily the effects lasted only 6 hours, but the rest of her night was basically ruined. She could normally take a prank like a champ, but she had not enjoyed having such a thing done to her on her birthday party. The worst thing about it was how the party just kept going without her once she left. Her old body could not take it, so she went home and went to bed, and her friends just posted pictures of their fun for the rest of the night.

Well, now she would play into his fears. He was obsessed with always appearing big and strong and that was her angle. She had ordered a strange serum of her own, and mixed the contents into a bucket of water. She had propped the bucket to fall and splash him once he opened the gate from the driveway to the backyard, like he always did when he came home from football practice. He always went to dump his gear in the back shed, like clockwork, so she knew she would hit him even though her contraption was simple. Becca heard the car pull up and waited with anticipation. Door slam, trunk popping open, steps, keys jangle, door creaking, bucket splash and female scream. The plan had... worked? No... it hadn't. Her brother did not scream like a girl. She went to check what the heck was going on.

- "What the heck is going on?" Letti just tried to get into her yard when a bucket of water fell from the neighbors and splashed her. Becca, the neighbors second oldest child poked her head over their shared fence. Lettie should have known, the redheads next door with their everlasting prankwar.

- "Shit" the young one muttered as she saw the 42 year old neighbor woman drenched and her bucket rolling around on the ground. The trap was rather flimsy she realized, but she wanted to make sure to hit her brother. She had not anticipated the force from the neighbor unlocking their gate would trigger the trap. She hadn't even thought of the possibility of the neighbor coming into the line of fire, even though they shared driveway and their gates to their backyards were next to each other.

- "Shit indeed" Letti laughed. After all, she was right at home and could easily change into something dry, no need to get angry over a prank gone wrong. She gathered up the groceries she had dropped out of surprise. Everything looked alright, but the bag felt rather heavy.

- "Miss Lettie, please don't be alarmed, but you are shrinking." the redheaded young woman appeared in front of her. "It's temporary, let's get you inside."

Lettie dropped the bag again. It was too heavy to hold on to. Her dress fell to the ground with the rest of her clothes and she stumbled out of her shoes and fell. As she got up and looked at her neighbor she realized of course that what she said was true. Lettie was shrunk. The usually petite cutie next door was towering above her. Towering was not a word that did it real justice though. Lettie lowered her gaze, and lowered and lowered... She tried to gauge how small she was. Looking straight forward she could barely see the top of the womans big toe nail. It was painted green. Lettie managed to summon a strange calm and spoke.

- "How temporary?" She got no answer. Naturally, she was too small to be heard.

Becca realized she probably should have diluted the mixture more. The target shrinking to an inch high seemed like a good idea, but Becca found little miss Lettie extremely hard to keep track of. She decided to pick her neighbor up. She needed to make sure she was safe. Had she not seen her neighbor shrink right before her eyes she would have lost her. The label did say "instant effect" but she really hadn't anticipated it working just this fast.

Lettie climbed on the the giant platform presented to her and sat down. This was not how she had expected the rest of this day going. Somehow she found herself giggling as the wind rushed about her. She was sitting naked in the palm of her neighbors hand, rushing up at speeds she didn't think possible. It reminded her of one of those theme park rides that just shoots straight up, except she had no safety harness or anything to protect her really. Lettie should probably have been more scared, but it reminded her of some reckless things she had done in her youth and that nostalgia seemed to win over the fear.

Becca was surprised to find her neighbor rolling around and laughing in her palm. It was not the reaction she had expected, but then again, it was not even the target she had expected. Glad she was enjoying the ride Becca took a moment to try and figure out what to do next. She had 20 minutes of this to deal with. It was lucky she was not as cruel as her brother. Six hours of this would be too much. Suddenly she heard the car of her actual target pull up on the driveway and felt a slight panic. It was probably best to not show her brother what she had done, especially if she still wanted to surprise him with this prank in the future.

Lettie saw the other neighbor kid pull up and then she didn't see much more. The world jostled, twisted and rumbled around her. And then everything got quiet and dark. She was hidden from view she realized. But she had no idea where. The first neighbor had closed her hand around her and placed her somewhere. Lettie was feeling pressure from the front and from her back. There was fabric behind her and warm skin in front of her. Peach fuzz, and a salty humid air around her. Lettie was in the bikini top of her neighbor. She was being gently crushed under a boob. A small boob. Had Lettie been her full self she would be able to fit her whole hand around that boob. Becca was a tall and skinny girl Lettie had observed. Not Letties usual type, but here she was, cradeled in the top of a petite woman and as far as weird situations go, it wasn't all too unpleasant. She laughed again at the absurd situation. She tried to turn around for a bit, hoping to get into a position where she wasn't so squished.

Becca managed to hide Letties clothes and groceries quiet quickly. She threw it all over the fence. Something in the shopping bag broke, and Becca made a mental note to replace whatever that was later. Her chest tickled, her right side. Lettie better stay still in there. She had tried to shove her neighbor in the pockets of her pants but the short shorts pockets were fake, so the top would have to do.

- "Hiya Becks. Did you forget your keys again?" Her brother looked unreasonably chipper as he unlocked the gate and disappered into the back with his gear. "So you decided to get your nipple pierced?" 

- "What?"

- "It looked like... something changed." Becca quickly felt her chest tickle. Her neighbor was climbing around under her bikini, and her brother must have spotted it. She gave her boob a gentle pat, hoping it would calm down.

- "Are you checking out your sisters boobs?" Her brother just laughed it off. If only he had known what she had in store for him... once she had solved this current situation. She went inside the house and into her room and made very sure the door was locked. Now... how was she gently going to get her neighbor out from under her right boob?

The world turned and twisted again. A cold breeze swept in and Lettie fell gently down in the fabric of the bikini. The giantess rose above her, chest naked. Marvelous, chiseled forms Lettie had never noticed before. The woman sat on her knees and looked down on Lettie. Lettie thought that they must be on her bed, judging by them suddenly being indoors, from whatever she could see over the fabric of her bikini prison. Lettie blushed. She had not been this excited in a long time. Literally swept away and brought into a bedroom.

- "Are you enjoying this?" Becca mused. She watched the tiny form almost glow red in the bikini top on the bed, nodding. "Or are you just warm?" Lettie shook her head. What a strange woman. How could she enjoy this? It was supposed to be torture... for her brother at least. "You need to keep calm or we'll get caught. He spotted you squirming about. He thought you were some kind of nipple jewelry." Somewhere in Beccas brain that thought flipped a switch. Wearing her neighbor as jewelry was something she never ever would have concidered before, but now that she knew it was an option? "Let's get you home before you grow..." she said quickly, trying not to let that thought linger. There was something scary about how easily that thought felt like a fun idea. "It will be very weird to explain what a naked woman does in my room. 15 minutes should be plenty of time to get you home though."

"You little minx." Lettie thought to herself. "You would have no problem explaining a naked woman in your room... I've seen the way you look at people, measuring them. I'm certain you swing all sorts of ways." Maybe a woman Letties age would be a bit different though. But from what Lettie had seen their parents were rarely home so it realistically wouldn't be a problem she would have to explain to anyone. Lettie could probably just stroll back home without being seen with how close their houses are... well... in 15 minutes at least. She didn't dare to think about how little ground she would cover at this size right now. And she didn't have to think about it. Her ride was standing in front of her, getting undressed for some reason.

Becca decided that she could live with undressing in front of her neighbor. It was funny how she needed to think about removing the rest of her clothes in front of the tiny one but she hadn't hesitated at all to shove her under her tit. There was something strangely comforting with being watched openly. Whenever Becca glanced over at the bed she could see that she was the center of attention. Her neighbor watched very carefully as she changed into her runners outfit.

Tight shorts and a sports top, and of course comfortable running shoes. Lettie had seen that outfit plenty of times, whizzing past her window early in the mornings. She did not usually pay much attention to it though, but it was hard not to find a new appreciation to go with her new perspective, plus now she knew exactly what was under it. It didn't seem to leave much space for her though, and Lettie was waiting with great anticipation to see where she was going to ride. The young woman stood by the foot of the bed and suddenly she flew up high. It was strange seeing something so big being airbourne. It was even stranger when the giant body slammed onto the bed, sending a shockwave rippling through the air and then Lettie started flying when the ground below her bowed and flexed under the immense powers of the petite godess.

With great care and precision Becca landed as far as she could from her neighbor but still on the bed. She wasn't sure what possessed her to do that, but seeing the tiny one fly when the bed springs bent back to their original shape after she landed was more fun than she cared to admit. And her neighbor actually looked like she was still having fun. It was seemingly impossible to wipe that grin of her face. Not that she particularly wanted to, it was just an observation.

- "Let's get you home then." Becca said when her neighbor calmed down. She turned so she was lying flat on her back. "Climb aboard." She had no idea where the tiny neighbor would go, but she was very curious to see what happened if she gave her free reign. It tickled slightly when the neighbor scaled her body. She used the shorts to climb with surprising speed. The slick material must offer good climbing grip when you were that small.

Lettie was taking in the sights as she was traversing the young landscape. It was strange how for a moment she actually wished to be smaller so she could climb down into her neighbors cute belly button. She had literally been blown away just moments ago by the force of a ninteen year old, and she wished herself even more powerless? Lettie shook her head. "Get a grip. You're going home." She made her way across the springy sports top and then she climbed into the tiny cleavage. There was a surprising amount of room in here. The small breasts compressed didn't expand much to the sides and lifted the fabric so Letti had some space to lay flat between the boobs. She heard a snicker and felt the chest heave under her, and then the world turned.

- "I'm going for a run." Becca declared to her brother, if he was listening. It was hard to know, he had disappeared into his own room. Becca realized she didn't really have a plan of what she would have done if she had shrunk him, but she was certain now what he would not get to ride in her bra. It was too exciting to have someone there, so close to her heart. She wondered if her neighbor could hear how fast her heart was beating in there. She had been so sure on how to scare him, but now every scenario she thought of with someone so small revolved around her own pleasure, and her brother should have absolutely no part in that. She exited the house via the backdoor, had a quick look around in the yard and then she jumped the fence into her neighbors yard. She found the groceries and the clothes right where she had tossed them. She dug the house keys out of a pocket in her neighbors dress and then she picked up all the stuff before she let herself inside. Becca started to unpack the shopping bag on the counter and she found that it was a jar of marmelade that didn't survive being thrown earlier. Becca was almost about to leave for the store to buy a replacement when she remembered that she had a person in her cleavage still.

Lettie was carefully placed on her own bed. She watched the giantess leave and within just seconds of hearing the front door close Lettie was her regular self again on the bed. It was strange being part of the regular world. Those 20 minutes felt both like an eternity and like they had flown by. She needed a bath, a good long bath to collect her thoughts, calm down. She knew she had a silly smile plastered over her face, she could feel it. The tub took a while to fill but she let out a sigh of relief as she sank down in the water. She heard the someone unlock the front door suddenly.

- "It's just me again. I brought marmelade." Becca announced.

- "uh... I'm in the bath." Lettie answered. She had no idea why her neighbor was back with marmelade of all things. She had been too shrunken to notice that the jar she just bought had been broken. In fact, she had forgotten everything about her groceries. This whole day was a strange haze. Suddenly her neighbor was in front of her in the bathroom. There was something strangely intimidating about the young woman... or exciting. Lettie felt dizzy.

- "Don't tell my brother what happened today." Becca had a strange smirk as her eyes moved all over Letties naked body. Lettie had seen that stare before, but never aimed at her.

- "I had no plans to..." Lettie did her best to seem relaxed. There was a powerstruggle going on right now, and she could not possibly win. Becca only saw a toy to be played with.

- "Yeah... be a good girl and we'll do this again some time."
