Half n half

Having sex in which half the time is oral and the other half is "regular"

She gave me a half n half

revenge of the sperms

When a girl purposely holds a freshly acquired load of sperm in her mouth, possibly pretending to swallow, then kisses the man while transferring the sperm into his mouth, probably followed by giggling and nipple twisting. He can't complain, he just got a bj!

Dude! That barista chick gave me a bj last night but then she gave me revenge of the sperms!
