Refuse to have sex with Mark

"I will not have sex with Mark. I don't want to and there is no way you can make me. Making out with you was terrible enough. My mum would kill me if she ever gets to know about it. Isn't Mark your boyfriend? How can you accept him sleeping with me?" I ask ludicrously.

Tiffany just smiles, "Mark is my boyfriend that is why I want to make him happy. I am sure my birthday present will make him very very happy. As long as he is not cheating behind my back I do not mind at all."

She moves towards her PC and turns on the monitor. I am getting pale and losing my breath upon looking at the screen. It is a video of me and Tiffany having sex. The quality was very good and it was obvious that I was a willing participant as it captured my face licking Tiffany's pussy eagerly. I have been more into it than I remembered making noisy, wet and sloppy sounds.
