hook up

I know a set of fraternal male twins. One is very gay, we are good friends. One is very straight, we have hooked up twice. The gay twin, let's call him A, is aware of the first hook up and wasn't very happy about it. When I talked to A about it, he said he wanted me to do what makes me happy but that I should ask for permission before I hook up with the straight one, let's call him B. That talk occurred after hookup #2. Later the next day while hanging out with a group of people including both twins, I was really tired and acting very annoying (I recognized after the fact) I very much annoyed twin B. I think I went too far and may have messed up an opportunity for an fwb. What do I do? Ps: I normally only see these twins once a week but this past weekend was an exception.
