I like your wife, lol.
My wife is similar and I love the humiliation that comes with being a cuckold. She won't get too harsh, but there are certain things she likes to do to humiliate me.
When she is having sex with her bf, she wants me to watch up close. She says it adds to her arousal, that I am watching her bf's bigger cock penetrate her pussy.
If her bf comes over for the weekend, she likes all three of us to stay naked as much as possible. She likes to show off her bf's bigger cock and naked body, to me, all weekend long, lol. I enjoy that as well. I'll stand close to her bf, just so I can see how much bigger his dick is compared to mine. Even in a limp state.
The ultimate, though, is she likes me to clean her pussy and suck her bf's dick, right after he pulls out. She says that is the ultimate way for me to show my acceptance, lol.
