Donkey punch

A mid-coitus rear cranial blow to induce vaginismus for increasing the hermetic seal upon the shaft to thusly restrict hydrodynamic semanal flow during orgasm in turn hightening sexual plesure.

Naturally, donkey punch also applies to any pugilisticly caused contrations of the anal sphincter during homo-/hetero- sexual sodomy

"Oh man, when I fucked Karen last night, I donkey punched her so hard that her cunt squeezed like a vise around my cock, and i thought it was going to break off as i nutted in her with such force, i swear i saw her cough up my splooge onto her tooth that got lodged in the wooden headboard"

"Wow thanks, I'm gonna try that when i wreck Bruce in his little bussy tonight"
