This is a smooth move that may turn shocking depending on the girl and/or mood. References the reach around during a kiss where you maneuver your hand around past the ass cheeks and into the snatch zone. Finger, pinch, rub...whatever “attack” method you choose will do. Enjoy!!
Oh man!!! Midget Joe tried the around the back snatch attack on his full size girlfriend and wound up with his finger in her ass.
