After graduating high school, you decided you were ready to get out from under your parents' roof. You got a full time job and pulled your savings together for a down payment on a decent apartment. Your job wasn't crazy high paying - you were a long way from living the dream. But it was a solid first step. Something you could call your own, live under your own terms, and start building something.
Your place didn't have many perks, but one of them was that you were surrounded by people your own age. You were fortunate to find a building that catered to people like you - starting off their careers and looking for flexibility. You didn't have to worry about older retirees or established career people who wanted to go to bed by 9. You didn;t have a building full of crying infants. The oldest person you had met outside of your landlord was 25. Most of the building was between your age of 18 and ranging up to 22 or 23.
The highlight of your building in your eyes was your neighbor down the hall, a tall athletic redhead named Amy. She was beautifully built, thick and toned thighs, a slim stomach with just the slightest bit of extra flesh, and an absolutely stacked rack. What caught your attention most though, was her full, round, bouncy ass. You had no idea how she kept her ass so seemingly firm while maintaining a bounce and a jiggle with each step she took with such limited fat on the rest of her body. But that wasn't your concern. You were simply happy to have her so closer by. You had interacted a few times - she was very friendly and welcoming when you moved into the building. You did your best to avoid stealing glances at the 21 year old's curves, but there was only so much you could do. Over the brief interactions, you learned that she was training for an upcoming marathon, which explained why you so frequently saw her in athletic attire.
That was the case when you walked outside on a beautiful Saturday morning to enjoy your day off. You didn't have anything in particular to do, but you wanted to do your best to enjoy the weather. You caught sight of Amy stretching and preparing to go on her morning run. She had a small gym bag on the ground near her. She saw you exit the building and smiled.
"Hey Tony! What a surprise seeing you up so early on a Saturday!" she said with a smile.
You chuckle and respond politely. "Yeah, I need to get some better blinds on my windows. I couldn't sleep in with all that sun shining through," you said with a laugh.
You continued to exchange small talk for a few moments when you noticed an odd look come across her face and she paused.
"Hey Tony, this might sound a bit odd, but would you be willing to do an itty bitty favor for me?" she asked in a sweet, pleading voice.
Looking at a beautiful woman like Amy asking you for help, you were in no position to refuse. "Of course!" you respond confidently. "How can I help?" you ask curiously.
Amy doesn't say a word. Instead, she reaches into her gym bag and pulls out something that looks like a toy squirt gun. A look of confusion flashes on your face, but before you can say a word she just smiles and fires the little gun at you.
"Huuuh?" you exclaim as you feel your world spinning out of control. The next thing you know, you're staring up at Amy, no taller than her ankle.
Amy shouts happily and quickly wraps her fist around you.
"Ok, I may have misled you a bit. It's you who will be itty bitty, not the favor," she says with a giggle. "Here's the favor. You know I've been training for this marathon for months and it's coming up like next week. No matter what I do, I can't keep my panties from riding up on me. It's super distracting. I thought I'd get used to it over time, but no matter how much I run it just keeps slowing me down. I need you to help keep me focused!" she says with a smile.
"You need me to what?!" you exclaim in shock. You can't believe what you're hearing. If you understand right, this beautiful woman is asking to put you in her ass and act as a barrier for her panties. Well, actually, she's already shrunk you. So at this point she's not really asking.
