She rides me

Kate suddenly unties her bikini bottoms and lets them float away in the pool. When she straddles me again, there is nothing between us and my cock slides right into her pussy.

"Oh god, Alan, you feel so good," she moans.

She leans in and starts kissing me again as she starts rising my cock. I had had no idea that this kinda nerdy and bookish girl was so hot beneath her conservative clothes. I grip her ass as she pounds up and down.

Amy is still watching us from the shadows, and although i can barely see her, i am certain she is rubbing her pussy.

"I'm gonna cum," I warn her at last.

"But...I am...almost...there," Kate moans, continuing to ride me.

"I can't hold it..."

A moment later I cannot hold out any longer. I grip her ass tightly as I start to cum, shooting a load deep inside her. At nearly the same moment I feel her pussy start to spasm as she climaxes.

When we were both spent, she collapsed against me, her head on my chest. I dont think I have ever seen a woman look as beautiful as she did in that moment.

"That was amazing," she whispered. "I think I'm in love."

"Me too," I said and really did almost feel it.
