Teased Over Ex-wife Cuckolding

My ex-wife was promiscuous, and in fact cut me off from sex while she was fucking her boss every day after work. She eventually got pregnant, we divorced, and I remarried.

My new wife wanted all the details and told me I was probably a cuckold because I wasn't big enough to make a woman cum. She laughed and said my mom would probably think it was funny, and that I should call her up and say, "Mom, mom, I'm a cuckold." I started getting hard and she pointed this out and said I'm a natural cuckold because it turns me on. Then she asked me if I'd mind if she went "out on the town" to find a "real man" with a big dick every so often.

So humiliating but such a turn on.
