Its a common response for newcomer wives and black sexuality. They are "taken aback" by their own feelings and responses and seek to hide and repress these feelings. Give it time and she will do it again. And again and again. She is likely trying to conceal her lustful feelings for black cock but it time this becomes impossible and she accepts the "new" woman she has become
Thanks for taking the time to answer. I appreciate the encouraging words.
Right now, I'm working on slowly getting her back to a place where she's comfortable talking about what happened and using it to fuel our sexual appetites, which it had been doing for a while afterwards
Last night, before we fucked and while I was rubbing her off, I started to drop hints about how much she enjoyed getting fucked by two cocks and how wet her pussy got. She would steer the conversation to MY cock only, and so I would incorporate that into the sex talk while steering it back to the threeway. For instance, when I would say something about how wet her pussy gets for cock, and she would judo it with, "yes, YOUR cock makes me wet," I would say something like, "yeah, I remember how wet your pussy got around my cock while you had that big black dick in your mouth at the same time." Stuff like that.
If you wait until she's the most horny, which gets more and more the closer she is to cumming, you can get away with a lot more. Even when she doesn't respond positively verbally, you'll know she's enjoying it because the mere mention will send her to the next level or over the edge. She came hard as I described how hot it was to feel her moaning from his big cock fucking her while her mouth was wrapped around my hard cock.
Doing that sort of thing right can reopen the door, or at least get you back from the brink. Patience and persistence are virtues in this lifestyle, especially in these early stages, I've found.
