Wurly Durly

A sex move where the girl inserts herself ontop the penis and begins to spin around like a basketball on a finger. The friction generated from the spin translates to the ULTIMATE PLEASURE for the dude.

Him: Babe gimme the wurly durly
Her: What's that?
Him: Spin on my dick
Her: Okay. *Proceeds to spin on his dick with her vagina*
Him: *cums*
