I think you might have better luck working toward a MFM thing, she may be more for a new cock , if u can find a real cocksman thst does her Bare and deepseeds her yearning hot pussy, id bet she would be Hooked,
And i bet your right, good married pussy will be in the back of his mind, once you fuck a friends wife U2 have a connection thats not easily put aside, or it always was in my case.
