I never had an o until my husband and I used this methodk,get iin the man on top position/missionary,have her close her legs and tilt her pelvis up(sometimes a pillow under the ass helps)now your pelvic region and hers should be able to grind together,so grind together and find a rythm and amount of pressure thats good for her.let her be in control(i grab my husbands ass while doing this to help me have control)it takes a little practice but she'll get it and be cumming in no time.omg I'm getting hot just thinking about this lol.oh ya,while grinding,your hard cock is in her and make sure she is nice and wet before you start.hope this helps.
