I can't find much about this fetish. I know about Hot Wife fetishists, where the husband gets off on organizing and watching sex between his hot wife and other men, but I'm looking for a gay equivalent.

I have a really good looking, well built partner and I love when he gets fucked by other guys. We have a good sex life and he often gets with other dudes, but when it's the three of us, the other guy always seems to want me to join in and I would much rather just watch, maybe jack off.

Does anyone else get off on this? How do you keep it going?
