Turkey Snap
Grabbing the penile head and intentionally pulling your stiff, hard, rigid cock to the side (left or right, your choice) the releasing it to quickly snap back and slap the cheek, lips or forehead of your girl. Typically done just before she gobbles the knob for a little hot oral. Repeat as desired.
Why is your cheek so read? Frank gave me about a dozen turkey snaps this morning before I sucked him off. That may leave a bruise.
