with gumi, so i may look like the pro one
threesome paradox:
u, a man, and a girl with a strap on are forced to have sex, and u have to be in the middle.
will u choose to get banged by the man and bang the girl OR bang the man and get banged by the girl's dildo?
take into account each of the variabilies: no condom, they man's ass is hairy, he can cum in ur ass, the size are pretty the same, the fun of banging a girl and so on!
