We've heard of vaginal sex, oral sex and even anal sex. The rarest one is penal sex. The act of inserting the penis not into a vagina, not in the mouth or the anus, but into another penis hole. OOOOOOOOOOOOOOOOOOOOOOUUUUUUUUUUUUUUUUUUUUUUUUUUCCCCCCCCCCCCCCCCCCCCCCHHHHHHHHHHHHHHHHHHHHHHHHH!!!!!!!!!!!!!!!!!!!!!!!
Me and Derek have penal sex regularly. It hurts but we take it in turns to penetrate. (I AM NOT GAY BTW)

When someone sticks their penis in someone else's penis somehow. Fags like to do it.

It can also be in futanari when a girl with a penis has a guy or another girl with a penis stick their penis in hers. Since its anime, anything can happen.
They had penal sex. I bet it hurt!
