You decided to go see Kelsi, and thank her for letting you move in. You've known her since high school and you wanted to go catch up with her and see how she was doing. You walked to her room and saw her unpacking her things, she was unpacking something from a box on the ground with her ass hovering just barely above the ground. She was wearing a pair of tight grey spandex booty shorts and a yellow tank top, her shorts were struggling to contain her ass and you could see she was only able to pull them halfway up her ass. You couldn't help but stare, it was the largest ass you've ever seen in your life, you didn't know how she made it fit into any of her clothes.
After spending a second or two enjoying the view you finally asked her, "hey Kelsi, would you like some help unpacking?" She didn't respond, you noticed she had her headphones on so you went to tap her on the shoulder. Suddenly, just before you were going to touch her you heard her fart, and as soon as the smell hit your nose everything began to rapidly grow in size. It took you a second but you realized you were just shrunken down to an inch tall. You looked up and saw her ass hanging above you and you heard it's owner say, "I knew I should have labeled these boxes, I just need to find my clothes, Carmen was nice enough to let me borrow some shorts and a top, but the shorts are way to tight and it feels weird not wearing a bra or a pair of panties."
