So, I made a dumb decision. You might recognize this sort of decision too. Your friend or friends dare you to do something stupid. Against all logic, you agree to it because you want to be cool. You want to be "one of the guys". Well, I got dared by my friends to swipe one of those body mod injector things from the kinky adult entertainment store a few blocks from the college campus. Regardless, I wasn't ready for the hijinks and misadventures that came from me walking into that store, snatching a nearby mod, and dashing for the door.
Author Note: Don't be afraid to rewrite bits to make it better or more tailored to you. The general inspiration behind how the body mod works is Trials in Tainted Space, but I think I at least left things open enough for easy deviation towards any preferred kink. You can go femboy, kemonomimi, futa, gender bender, bimbo, himbo, or whatever else you feel like. I feel the only downside to this prompt is that I had to railroad it with peer pressure. I just hope someone has fun with this. :)
