I worked on a little subtle pillow-talk last week. She was telling a story about an instructor at her gym (who is black) and I was caressing her inner thighs while we were talking about him. I kept encouraging her to talk about him more. She seemed somewhat in to him.
I just learned that she quit that gym and moved to a new one closer to home. Just when I thought we were getting somewhere.
Maybe there was something going on?
How Do I find out?
Maybe now that she does not go there she will be willing to explore with him?
Perhaps something did happen and she doesn't want to face him again as it's too awkward, or she's worried that something would happen if she carried on meeting him? I'm not sure anyone can advise you on how to find out - does she know you'd like her to experience another man? If so, you could always let her know that it's a shame she moved gym as that 'black guy' might have been a possible contender for her? Or.. let her know it's a real shame she didn't get to fuck him before she left that gym, and nothing would have turned you on more? If nothing else, this might lead the conversation in the direction you want it to go.
