So I'm 100% gay, and lately I've been seeing a Dom who wants me naked, collared, locked, the whole nine yards. He'll piss on me and I'll clean his house for him (it's not a TPE thing, but we meet up fairly regularly)- but now, he wants me to have sex with his other sub, a young woman about my age, while he watches. I have no interest in sex with women at all, but I find being a submissive slave to be extremely arousing, and I'm not completely against the idea. Being subservient just ticks all my boxes.

Any subs, slaves, and bottoms on here- what would you think of such a proposal? Has anyone been in a similar situation? Should I go through with it?

Incidentally, in the fetish group he operates, he has also done it the other way around- he has had a macho, rugby-player straight guy bottom in gay sex (everyone involved is completely consenting, of course) which is about the hottest thing I've ever heard. What do you guys think?
