Finally you pull up into the parking complex of your modest apartment downtown. You quickly get up and out of the car, only to stumble and fall onto your hefty the hefty booty on your chest, unused to the heavy butt pulling you down. Huffing and puffing, you snake an arm underneath your upper ass and stand, realizing that your scrawny muscles won't be up to the task of handling your new and bizarre assets. Luckily for you, it was at this moment that one of your neighbors was walking by, apparently after finishing up at the gym.
Jessica was a female body builder, the kind that felt an odd need to post about themselves on instagram far too often. She wore her workout shoes, yoga pants that showed off her trim thighs, and a tight fitting tank-top that left little imagination to her porcelain bulging arms and shredded torso. You never really talked to her though. She was fairly unapproachable at the best of times, and her face was just as hard and stern as the rest of her body, and her frazzled red hair was perpetually kept in a bun. You weren't concerned about that, though, you just needed that muscular core and her big yet still feminine arms.
Leaning against the car for support, you zapped her arms and torso with the device, then hit the reality altering button so no one would notice. It was so bizarre, even more so than the others, as her arms appeared to help with the detachment. She stopped, her face unreadable, as her arms detached her head and placed it on the ground where she nonchalantly waited. Then her muscular arms shucked off her top and small sports bra and peeled off her small B-cups and placed them on the ground next to her head. They then pulled themselves and her torso up off of her legs and hips, leaving there standing, empty from the waist up as her upper body sans breasts and head hand walked easily over to you.
In preparation you zapped yourself and felt your arms take on a mind of their own to as they did the same to your body, placing the fat ass on the hood of your car, along with your head as the two upper halves traded places. Jessica's toned upper body hopped onto and connected to your stolen black lower half. The arms reached over and placed the jiggly butt onto its fit chest and then reattached your head. You felt an immediate difference, noticing that your beck didn't hurt at all now, even with the strain of almost fifteen pounds of ass hanging off of you. You flexed your new muscular arms as well, admiring their tone and giggling at the feminine nails you didn't expect.
Looking back, you saw Jessica already walking off, your weaker torso and arms carrying her gym bag, and her breasts attached to your much hairier chest. Laughing, you nearly started to walk to the elevator when you had a niggling thought rise from the depths of your mind. You still had a manly head and face, but an admittedly much more feminine body. You had to fix that, but how, and with whom?
