Spidey Punch

Climbing up on a person to have sex with them from behind and resisting their attempts to dislodge you with Spiderman web throwing manuevers.

Can be the throwing of semen into the hair of the resistor after they successfully dislodge you.

I climbed up on her from behind like Spiderman. She wanted face to face action so I Spidey Punched her and carried on.
