well I start wit the abs. and work my way down then go back up to tease him.
it really works

If he grabs your butt while kissing, go ahead and put your knee/leg in his crotch. Not hard, but just enough so he can feel it.

As for your hands, just put them on his neck and or hair. You can also move his arms down to your butt if he isn't putting them there; depends on how serious you are.
