This has been a relatively new and very different experience for us. About a month ago my wife was introduced to a younger guy who is 33 years old and as my wife describes him he is an Alpha Male with a very dominant personality. She says he is moderately athletic and in decent shape. He spent eight years in the Marine corp and has been out for a few years. She says he has a very "nice" cock which she says is slightly larger than average at around 7". I have not met this guy or spoke with him. He knows I am here but will not allow me to accompany my wife when she meets him. He sends me a text a few times a week telling me he needs to be serviced and to bring my wife to him. She thinks this arrangement is hot and he gives her butterflies in her stomach. She says it is purely sexual and there is not any feelings or love between them. She tells me they mutually use each other for pure physical pleasure. I drive her to his place and then drive around waiting on her to text me to pick her up once they are done. I have not seen him. He tells her what he wants her to wear and apparently is very dominant sexually which my wife says drives her wild. She says he has amazing stamina and can fuck her hard for over an hour before he will climax. She says she climaxes multiple times during sex with him. He refuses to wear a condom but says he will not cum inside a woman but loves to cum on her stomach, tits or ass depending on their position at the time. When I pick her up his cum is dried on her skin and she is usually sore. Their meetings typically last in the range of 2 - 2.5 hours and she says there is really nothing other than sex the whole time. He usually cums 2 or 3 times when they meet. It drives me wild wondering what they are doing and just thinking about him using my wife. I have tried to engage him in text but never get a reply. He and my wife don't text or talk on the phone, it is just taking her to meet him when he is horny.
