The guy in the next apartment has had sex with almost everyone in the complex. My wife thinks he's "sweet" and spends hours at his apartment while I'm at work. I tried to act like I'm not concerned about it and told him that I can trust my wife and I'm not worried. He told me I'd "better be worried." He claims he can fuck her anytime he wants, that he's just been holding back out of respect. I'd be devastated if my wife fucked him. He told me he'd make a deal - that he wouldn't fuck her if I sucked his dick. I told my wife about his interest in fucking her (but not about his "deal") and she said "He's too much of a gentleman to ask" but was evasive when I asked if she'd fuck him if he did ask. Not sure which is worse, but I think sucking his dick without my wife knowing would be less of a problem for our marriage than if he fucked her.
