Wow, that sounds really cruel. While still horny, I can imagine another man having his way with my wife and take joy in her pleasure. But after I come, the thought horrifies me, and my jealous thoughts consume me.
To be ****** to watch my wife getting brutally fucked after I have an orgasm would be unbelievably excruciating, but that experience would probably be very important for me to go through to really help me discover if I am destined to be a cuckold, or just am a guy with a fantasy that sounds good while horny. To prevent me from stopping their coupling either way, however, it would probably be best for her to keep me locked up while she went on her "date", videotape her ravishing, and then have me to watch it, post-orgasm, when there was nothing I could do to stop it. All I could ask for in return is that the camera stay focused on her pretty face, so I could watch only her and remember that her pleasure justifies my pain.
