Swap Genitals

James had a very messed up mind, with his first thought being to swap the genitals of his sister with his. He had always thought what it would have been like to have a vagina, but if the manual was true, his chance was now. James grabbed the phone in hand and began to think of his wish. He wasn't 100% convinced this would work but he didn't have anything to lose.

Suddenly, James began to feel a warm sensation between his legs. It only lasted a couple of seconds but when it was over, James stood there frozen. Did it work? He placed his hand where his bulge would usually be, finding his groin to be a lot flatter than it used to be. He pulled his trousers and pants down revealing his sister's pussy, hairy and moist. It was beautiful. But some reason he had an urge to do something.
