Unknowing girlfriend turned into a sex slave by her lover

The scene opens with a beautiful brunette, who is the girlfriend of a man who seems to be her perfect match. The couple is enjoying a romantic evening, when suddenly, the man's friend enters the room. The friend is a well-endowed man with a big cock, and he immediately takes control of the situation. He starts to touch the girlfriend's body, and she is completely unaware of what is happening. The friend starts to touch her in ways that she has never experienced before, and she begins to moan with pleasure. The man then turns to the girlfriend and tells her that he has turned her into a sex slave. She is shocked and confused, but the friend assures her that it is all part of the game. The video then moves to a POV angle, as the girlfriend is taken to a room where she is tied up and blindfolded. The friend then proceeds to take her from behind, and she experiences an orgasm that she has only dreamed of. The video ends with the man and the girlfriend making love to each other, and both of them satisfied with the experience.
