My hotpast kink is too much for my girl

My girl (27) and I (26) aren’t the kinkiest ever, but we certainly don’t mind trying something new from time to time. We’ve dirty talked about sharing her, but she’d like it to stay firmly in the realm of fantasy unfortunately.

Last year, we went to a Halloween party at her ex’s house (we’re pretty good friends with him). She wore a sexy costume that showed off a lot of cleavage. Most of our female friends are pretty flat, so she stands out anyway. But with her 38Ds in a push up bra and a low cut dress… it’s pretty nuts lol.

When we got home, we were having sex and I told her how hot I find it when she shows off around our friends. She asked if she looked hotter than all our friends’ wives/gfs and I told her that they were all looking at her, wishing she was theirs.

Dirty talk then turned to her ex, and she asked if I thought he was looking. I told her he was probably so fucking hard seeing her tits, missing them. Even though his girlfriend (another pretty good friend of ours) was also there, she’s so unbelievably flat.

My girl told me that he used to love fucking her tits and that he gave her one of the only cumshots she’s had. It made me so fucking horny hearing her talk about sex with him, so I kept pushing it to get more details from her.

She had a pretty good time dirty talking about it that night, but when I’ve tried to do more hotpast dirty talk, she hasn’t been as into it. I’m hoping we have another experience that makes her want to talk about it more, because it was so hot having sex with her while she talked about how he used to fuck her. Even got her to moan his name a couple times and fantasize about sharing her with him.
