Pegging By Older

There is a divorced woman that I have sex with. I met her and fucked her about 4 years ago, she was 37 then, now 41. She has a nice body, plump but really nice and firm, big tits that don't sag much and she has let me have sex in all ways possible. For the last year she has been pegging me, using a strapon dildo and fucking me in my ass. She started by letting me fuck her ass then reciprocating. It's very embarrassing sometimes if her friends are over, she shows them pictures and videos of me fucking her in various ways, even fucking her while wearing her lingerie, and now she shows me getting fucked. Lately she talks to me like she wants me to let her have a guy over who wants to fuck me. I don't want to do it, and if she insists, I don't know what I'll do. I may let him, I really don't want to stop fucking her, she's incredible. She's even let me fuck some of her friends, mostly older or fatties, but I fucked them anyway.

I know if she gets me to let a man fuck me she'll video and take pictures. I really don't want that.
