Sex with clothes on

Position the girl on your knees. Just turn her back to you. 

Squeeze her breasts with both hands and ATTENTION  MAKE MOTION WITHIN THE CLOTHING, AS IN SEX, IN THE AREA OF HER BUTT

That kind of “sex” through your clothes might make you uncomfortable, but many girls achieve orgasm with just that kind of focus.

 Take off her panties and let’s get down to business.
