Gay husband submits to wife's desire for another man

Married man kinks out with gay sex while his wife watches. He\'s into BDSM, she\'s into threesomes. He\'s a submissive, she\'s a wild one. He\'s okay with it, even participates. It\'s a weirdly kinky setup, but it works for them. They\'re into it, and it\'s not hurting anyone.
