Spread your legs a little

You tilt your body slightly, just enough to give him a better angle.

Shifting just your eyes, you look over at him while still pretending to watch the movie. He continues to stare intently at the screen even as his hand slides all the way up your leg.

His fingers brush over your sex and slip just slightly inside. He twirls them around a little, getting them wet, and then pulls them out and begins rubbing circles on your clit.

You can't help but let out a soft moan. He turns his head to look at you, a smile on his face and a twinkle in his eye. All pretense of watching the movie now gone from his demeanor.
