Would you like to have a masochistic man cum by putting on a strap-on over a micro bikini?

I called out to an amateur lady (a pair of two who seem to be close to each other) on the street, "If you wear a micro bikini and wear a strap-on and make the masochistic man cum a lot, I'll give you a prize," and the two close friends tried out the challenge! The girls who were initially shyly shaking their hips, but the masochistic man's reaction was so exciting that he was excited and turned into a sadistic, super sexy woman! From words to hips to everything else, to becoming a sexy woman! I was supposed to just put on my penis and tease a man's anus...
