This just happened today. I love this site.
My boyfriend and I were lying down watching a movie and feeling kinda good. I had put his hand down my shirt and he started feeling my breast. He then took his hand out and moved it down towards my pussy on the outside of my pants.
Then he unbuckled my belt, unbuttoned my pants, and slid his hand down into my thong and started rubbing on my clit. He rubbed my clit to the point of a great exploding, whole body shaking orgasm in my thong.
