you go to your local gym for the first time feeling like you need to gain some muscle and or lose some pounds, tho you realize you need a gym partner, and so you go to the front desk asking if any trainers are available, there’s one and her name is Mia, but they warn you that she’s a handful, you shrug it off thinking it’s nothing, so they call them over and you see the 6ft big blonde haired woman with her hair in a pony tail and a pink hairband, a teal sports bra, and blue legging shorts and sports shoes, she’s tone, with a pair of large breasts and very huge thighs and ass that look extremely soft, she has pink eye shadow and lipstick and she’s texting on her phone with an annoyed look in her eye, that’s when you realize she’s still acts like a bratty high school girl, they mostly respond in “whatevers” and likes, but once again you shrug things off and get yourselves a room, and this is where you learn she has a special way of helping her trainees work out, on her phone she has a body modification app, that has one big scale, she immediately shows what it does as she brings it up two meters, her whole entire body grows bigger, making her taller, she says “like the only thing you’re gonna be weight lifting is me”..and so..you do

it cuts to you laying your back on the ground, with your hands on her massive ass doing your best to keep her up in the air, tho you are doing a good job she is REALLY heavy as she can feel your arms shake as you slowly push her up and down

“Ugh, can’t you go any faster?”
