Just an idea that popped into my head.
A touch of magic
Girl's husband has the ability to magically induce incredible orgasms. Though he used it in college to get a reputation (and thus to get more sex), he's never used it on his wife because doing so doesn't give him any pleasure and he doesn't get enough sex as it is. He doesn't want her to know about his gift because it's so powerful that she wouldn't want regular sex any more. And he doesn't want to make her have sex for it because he knows she won't be as enthusiastic (and might resent it, too). So, he comes up with a rather simple plan.
He uses a bit of his power on her (just a pinch) after convincing her to have sex. She has the best orgasm she's ever had. This leaves her wanting more, and the next day she tries to initiate sex. But he declines, saying last night was great and he just doesn't feel like it. Considering how great it was for her, his lie is somewhat believeable. Then he tells her maybe this will make her feel better, and touches her arm with one finger and releases all of his power.
Now, this gives him no pleasure at all (it's a one way gift), but he knows she'll want more. He apologizes to her future request, but explains (lies) that his magic just won't work if he's feeling horny, and that the very act of being asked to use the power usually makes him think about sex.
She tries dressing less provocative, but he knows why and points out it's only making him hornier. Soon, she is desperately trying to end his horniness. The only method that worked (or appeared to work in the past) was to just give him great enough sex that he doesn't want any more. But eventually, even this stops working. Though he has rarely used his power, his wife is already basically his sex slave. Eventually, she even gets despearate enough to start finding her husband other girls, even having sex with them too. She even starts to enjoy it, though it is likely this is at least partly just a pavlovian response to the rewards she gets out of it. Although plenty of rumors spread that his wife is a slut, there are a couple of lucky women who make her husband not be horny (or so he claims when he uses his power on them) and this rumor spreads even faster (though nobody believes it except those lucky few).
What he never tells his wife, of course, is that he is always horny. That's part and parcel with his magical gift.
