I need to build a registry where trannies are paired up as going opposite directions and just undergo complete genital-region swaps with each other. If you get the cuts right, it'd be practically outpatient and modular. You could change it up for a fun-filled weekend and be back to normal Monday morning. I always wanted to grow up to be like that pimp from the Star-bellied Sneeches. Oh man, Swap-a-Crotch here I come.
