She was right.
Maybe it would be better without panties then ?
Your wife's sister has been cuckolding her husband for a couple of years, and you knew that she had been trying to convince your wife to cuckold you (as a way of dealing with the fact that your wife found sex with you to be quite unexciting) -- so you were not at all shocked when your wife confessed, a few weeks ago, that she'd had sex with one of your friends. Since then, the two of them have spent several more nights together, while your wife has stopped being receptive to the idea of also having sex with you.
This is the bedroom of a man she recently met at her gym. The first time they chatted, he had told her how lucky her husband was to have such a beautiful and sexy wife, and he asked what you did. She had laughingly said "Oh, he's just a cuckold". Of course, she knew that wasn't what he had meant by the question, but as soon as he got that answer he asked her out on a date.
you only live once...
He fucks her in ways I question many things.
