Push her away before it goes too far.

As you make out, Rachel slides her hand up your thigh, obviously wanting to cop a feel of your pussy. You break off the kiss, bashfully pushing Rachel away before she can get her hands on your goodies.

Rachel smiles at you sweetly. She looks over at Richard as she says, “Aww, she’s shy.”

Richard nods to her and says, “Yeah, but I’m not.”

Rachel coyly says, “Oh?” She gets up and saunters over to Richard, telling him, “Well, let’s see.”

She straddles Richard, letting her butt sink down into his lap, and begins to rock her pelvis back and forth. Kissing Richard deeply, Rachel begins to swing her hips in a circular fashion, giving him a sexy little lap dance. After a moment of grinding her crotch against him, Rachel slips off of his lap and gets on her knees between his legs. She skillfully unbuttons Richard’s pants, and tugs on his jeans and boxers at the same time, pulling them down just enough to let his already rock-hard (and actually kind of big) cock spring free. Rachel grabs it firmly, and puts her mouth around the head. Her long hair falls forward, blocking your view of Richard’s penis, so that all you see is the back of Rachel’s head bobbing in his lap.

Sitting on the couch, listening to Richard’s soft moans and Rachel’s wanton slurping, you feel very aroused... and a little left out.
