Mature wife gets woken up for doggy style by her friend's mom

A man wakes up to find his wife being pleasured by his friend's mother. He's not particularly bothered by this, as his wife is quite the whore. However, he does have a bit of a problem with his friend, who seems to be getting a bit too close to his wife. The friend is clearly into her, and she's into him. This leads to a rather interesting situation, as the husband decides to confront his friend about it. The friend, however, is not interested in his wife and is only using her for her skills in the bedroom. This leads to a rather intense argument between the two men, with the wife caught in the middle. The friend is clearly cheating on his own wife, which is something that the husband finds rather upsetting. The wife, on the other hand, is quite happy with the situation, as she's able to get some good fucking from both men.
