Need Help finding a story

I found a story awhile ago about a guy and his girlfriend. The story began with him about to watch a movie in the living room to which his girlfriend walks in. She tells him that they should have sex during the movie. She begins riding the guy as her friends also walk in to watch the movie. She sits on top of him while they watch and rides slowly. She then keeps going and the guy has to show her a message to slow down to not bring up any attention. She tells him to pinch her when he’s close. He then pinches her and she tells her friend to sit on his feet and tickle him. He then cream pies her and they all finish the movie.

Does anyone know of this story?
