I'm not a girl, but here goes: kissing and licking his jaw, neck and hear softly. I think this works with any guy. It drives them all crazy.
hm hm I personally love when a girl gives me her back and rubs her butt angainst me while looking straight into my eyes....among other things.....
Pressing my breasts to his chest, kissing his neck and nibbling his earlobe, even wrapping my legs around him. he loves that.
I guess I really never paid attention to it. I can't even say what I do, but whatever he still gets hard so no worries I guess...
kissing him on his ears and neck, whispering how much I want him, rubbing his chest, pressing my body tight against him so that I feel him getting hard against my body, wearing skimpy clothes ....all these and more work for me.
