Wow, well congratulations, that’s very exciting. We don’t really tease about cuckolding apart from my big dildo, who I’ve called Adonis and I make hubby use instead of him, ideally on a strap on (I just posted links to them).
In my strong opinion cuckolding is best left a fantasy. I know it’s a huge thing for some people but I’m a big believer in monogamy and wherever you introduce someone else into a relationship you’re losing control of what happens.
