most like dry sex. mix b/w humping and sex. just with your clothes on. best achieved when the male is in a foldable chair. hehe.
guy sits in chair, girl strattles guy. girl rubs her _____ aginst the guy's penis.the guy also does work in this process. while the girl is humping the guy is doing just the same. until their movements are in tune. and both get overly stimulated, hehe
