My wife likes it when I pump my cock deep in her Ass. She gets even wilder when I start pumping her hard. I'll bury my cock and pull it all the way out then bury it again, over and over.
We've had several 3-somes with both men and women, and the last time we had a 3-some with another guy I told her that both of us guys were going to fuck her ass.
When she was on top of me riding my cock in her pussy I pulled her into me as our friend pushed his cock in her Ass.
She had about 4 hard, intense orgasims.
It was awesome to see the look on her face as another cock fucked her ass while I fucked her pussy.
