My gf started fucking BBC while we were on a break

We dated for a pretty long time and we’re the only 2 people we’d both ever been with. About 6 months ago we went on a break but we’re still talking. It was then she met this big black dude that was interested in her. She eventually says hey I’m going on a date with this guy which ends up turning into her going back to his place and staying the night. Didn’t know it at the time but they fucked too. We kinda separated for a while and she went crazy with him apparently they were fucking everyday, she completely turned into a sex crazy girl which she’d never been before. We started to get back together and I was telling her I would do anything to get back with her and I guess she hadn’t had sex in a while (which I found out was 2 days) and asked me to eat her out in my car. I did and that was it dropped her back off at home later. We did this for a while with nothing in return. Finally when we were going to have sex again for the first time she asked me if I still had the cock sleeve we used to play with…. I was like ya why and she said I’m not sure I’ll feel it very well without it. I was shocked but did it anyways. We’re still in the talking phase again but she’s different this time. She’s been thru many BBCs since we broke up and I think is much more away of the BNWO now. She’s been telling me all these sex stories thatve been the craziest BNWO truth I’ve ever heard lol. Now she’s talking about getting back together but doesn’t know if sexually she’ll be able to with just being with me…
