Deepest fantasy?

I’ve been asked what mine is and I feel like a virgin not really having one or it being lame. I’m 42 with a FWB and I like it rough and somewhat aggressive. He keeps suggesting bringing another girl in. But I don’t know any girls I can trust to ask and be clean. Also, he cums quick so that might be sort of boring. He says he can cum twice. I don’t want to see him banging another girl. Maybe just touching and masterbating. I’m open to ideas. I just can’t think of any. LOL

What’s yours?
