I've had a good few meets now, including several duos, and I seem to be able to last for a surprising amount of time from receiving oral. My first ever meet though, was with the now retired red trixy, she went at it like a dyson, and also went for anal play, not sure if she hit prostate or not but I lasted only a matter of minutes and was left hanging on to the mattress for dear life! It was probably the strongest shoot I ever had. Maybe a combination of not shooting for a few weeks, 69 with rimming and prostate play will get things moving. If not hand job until you are ready would presumably work!
