Oh boy, I had way too much fun writing this. Like WAY too much for my own enjoyment.
He’s really into being a bottom, dominant or not, so he wouldn’t care either way. He’d really like if his s/o was more dominant though, especially if it involved femdom or pegging. He’s willing to try anything.
He really would not be into this. I mean, he’d like the challenge, being a total dom himself, but he’d likely get annoyed by it after a while. He’d probably try to use a lot of bondage or something on you, in an attempt to keep you down, but I’m sure his lover would love thinking about returning the favor.
