FWB wants to fuck my wife

I (42M) have been meeting up with this guy I met on Grindr for a few months now. We’re both married and neither of our wives know. 99% of the time, we’re both just your average suburban dads except when we get together.

I’m not a full crossdresser, but I do enjoy wearing bras and panties under my regular clothes and shave my whole body. Since the beginning, I role play as a woman whenever I get together with my FWB. He uses feminizing language when talking to me. For example, my hole is a “pussy,” he sucks on my “tits,” and my dick is ignored, pretending it isn’t even there. We both enjoy it.

The last few times we’ve hooked up, he’s been talking about how he wants to fuck my wife too. I’ve previously shared with him that I would find it extremely hot if I found out my wife was cheating on me, and I’ve let him look through her pictures on Instagram while I blow him. At first, I thought it was all just part of our dirty talk while he’s fucking me, but he’s made it clear that he wants to actually do this.

Last weekend, he suggested that I could introduce him to my wife as a new friend of mine. Here’s my issue though, I don’t want her to know about me enjoying dick or to find out about what my FWB and I get up to together. My wife does know that my first sexual experiences were with guys, but that’s it. My FWB insists he wouldn’t tell her and just wants me to introduce him so he would have a reason to be in contact with her. That way, he could slowly become friendly with her and try to seduce her without me being involved so she wouldn’t find out about my submissive bi side.

I know all of this is a bad idea, and the potential of it blowing up is huge, but I also get really turned on thinking about the possibility. So far I’ve resisted committing one way or the other.
