Reply To: I think I’m turning my girlfriends husband into a cuck

It seems to me an appeal to his husbandly duty is in order.

She should ask him: “Is it part of a husband’s duty to see that his wife is as sexually satisfied as possible?” When he says yes (and how could he not?), she should follow up by asking him: “Then how can you deny me the superior sexual satisfaction that I get from [You]”? She should tell him that by allowing her to have sex with you, he would be fulfilling his husbandly duty … *he* would be the conduit through which she is provided sexual satisfaction, by choosing to share her with a man who can provide her those sexual thrills … and consequently it would make her love for him grow by increasing her appreciation of how he supports her sexual satisfaction. And if he learns something about satisfying her through her sex with you, so much the better, he will even better be able to fulfill his husbandly duty. It is a win-win for him.

Let him stew on that for a day or two, and the conclusion he should reach is pretty inevitable — of course as her husband he should be facilitating her sexual satisfaction.
