I made my girlfriend orgasm in front of…

Years ago I was dated this girl. I’ll call her Ann (short for anonymous).
Ann had a kid who’s grandma (her child’s dads mom) lived in a different state. A couple time a year she’s come to see her grand child and stay the weekend with us.

So one night, the kid was in bed. Just me, Ann, and grandma in the living room watching TV. Ann and I were in the couch. She on one end, me on the other.
Grandma in a chair across to our right.
Ann was half laying/leaning on the arm. One leg laid flat tucked under her. The other…imagine sitting cross crossed with legs bent at a 90* angle leaning against the arm of the couch. Under a blanket.
Suddenly I got an idea. Ann was pretty adventurous sexually so I thought I see how far I could go.

I moved down to cuddle with her. Got under the blanket. Waited a few minutes to make my move.

She wore shorter short which showed off her tan thick thighs and thongs. Showed off her amazing curves. I begin rubbing the outside of her leg…..slowly moving to the back…around to the inner thigh…and moving down toward my target…the beautiful shaved pussy.
