Scorpion skull-fuck

The act of mounting a girl and aggressively thrusting into into her oral cavity whilst simultaneously reaching around with your non-dominant hand to finger her vagina as if you were a scorpion stinging it’s prey

“Hey, Bob did you satisfy that girl last night?”

“Of course, I fucked her face, but gave her the good old scorpion skull-fuck so she could enjoy it too. I’m not a selfish lover”
