Recently I persuaded my husband to allow a guy he'd arrnaged to have a threesome with us, to also fuck him. Far from being repulsed when he took the guys cock up his lubed ass, my husband became extremely turned on and began fucking him back. Not only was my husband turned on, it made me amazingly horny watching him being fucked. Indeed when I came from my husband tonging me, I had probably the messiest and strongest orgasm I can remember having, as I squirted all over his face and the bed. It's been a few weeks since he was fucked and I've asked if he'll repeat it for me, but he says it will mean he's gay or at least bisexual, so he's refused. How can I convince him it would only be for our enjoyment and I wouldn't think anything less of him??
