Encourage him

With the table cloth hanging over as far as it did, it would have been difficult for anyone to see what he was doing. I slowly reached down under the table, put my hand on top of his, and whispered into his ears.

"You know, if you're going to grope me, then do it right," I said as I pulled his hand up inside my legs and against my crotch. I could feel the pressure against my pussy through my shorts and my heartbeat quickened as I looked around to see if anyone was paying us any unusual attention. The room was so crowded and noisy, he probably could have fucked me and nobody would have noticed but I wasn't about to test out that theory.

"Mmm, so the stories I heard are true, you really are a wild one," he chuckled as his fingers pressed against mine, "Bet it's been killing you being surrounded by so many hot guys but not getting a chance to fuck any of them." His finger pushed hard against my clit and I almost jumped out of my seat. Bastard! He knew I wanted it and he was taking full advantage of the situation.

About that time the teenagers reappeared, bringing what looked to be half the buffet back with them. David quickly removed his arm from my crotch and acted as if nothing had happened.
