She’s embarrassed and I’m sure if she ever does it again she’ll be thinking of you and other women the entire time getting pissed and insecure. This was a major fuck up. I’d say your best chance of getting her to do it again is to talk to her about it. Mention it would mean a lot to you if she tried and that you’re sorry. Say that you ARE going to make it up to her and show her how much you appreciate her. Then SURPRISE her with a mini weekend vacation and go down on her and refuse to be pleasured yourself all weekend. “ it’s her appreciation weekend.” Nothing worse than not being appreciated and just being treated the same afterwards. Good luck haha
