ok lesson for today is
donkey punch - n.
Having anal sex with someone and punching them in the back of the
head to make them pass out. Said to induce a clenching of the anal
sphincter in the unconscious person.
"Banging a girl doggy style and then moments before you cum,
sticking your dick in her ass, and then punching her in the back of
the head. This gives a tremendous sensation, but for it to work
correctly, the girl must be knocked out so that her asshole
tightens up."
