Thankfully for you, the device did not take too long to charge up. Almost to your house, you spot a woman walking down the street, a tall slim balck woman with assets identical to the girl you stole from earlier. She has long braided hair cupped by a large pair of headphones that block out the outside world from her. What catches your eyes as you roll up beside her, is her large squishy ass that waggles back and forth in her straining yoga pants. You feel like you can't leave here without her luscious butt, but you already have one you love attached... but then you remember the devices properties! You don't have to swap similar parts, you can swap mismathcing pieces too.
Excited, you park the car and hop out. Pointing the device at the oblivious woman, you zap her fine butt and watch with glee as her pants fall down and her ass lands softly on the ground with a delicious squish. She barely has time to react before you hit the normalize option and she continues unawares. You then quickly zap you own chest, your males nipples falling off, and swap them for the big black booty. Your nipples attach to her thighs will her butt now stands proudly on your chest, like a pair of oversized nipple-less breasts. You rub and squeeze your new bounty, amazed that it also came with the woman's tight and sensitive anus. Struggling to pull your now very tight shirt over your butt chest, you hop back in the car and drive home.
