I am not doubting her count, considering it was Sunday morning and Sue and Paul had from Thursday evening to Sunday morning to accomplish that. As STB has written before, Paul quite often comes over and can go a hour or longer, by pacing himself, withdrawing after giving Sue and orgasm, then restart and give her a second, and third orgasm, before he cums himself. STB has also written before that Paul and Sue go once in the evening, with STB in attendance, then Sue asks for private time and Paul and Sue go a second round with Paul having a last orgasm. Then the next morning, Paul is 'raring to go' again. So three in a 12-14 hour period is his normal. Considering Thursday evening - Friday morning, Friday evening -Saturday morning, and then Saturday evening - Sunday morning: nine for Paul is not abnormal.
What is more amazing is that Sue can come 2,3 or 4 times for each one with Paul, so she had about 30 orgasms in 3 days, and they still had Sunday evening - Monday morning. I can imagine Paul having 12, or maybe 13 orgasms(he may have saved his best effort for the last night?) and Sue about 40. That is amazing in just 4 days.
STB, I can sort of see Peak's point. Sue has been denying you for so long, maybe hoping to build your passion for her, and reduce your desire to be a full-on beta. When she allows you PIV sex, either condom of bare, don't look a gift horse in the mouth, by taking your opportunity, and then expressing remorse for falling off the wagon. Embrace your love for Sue and don't look back. It appears Sue will do enough denying you for the future to keep you satisfied, just be enthusiastic when given the chance.
