I like extended bouts with multiple shots. I have done 10 in 24 hours twice... book-ends for my marriage, so to speak...
The first time was on my wedding night. My then wife was still a virgin. We made love 5 times that night after getting back from the wedding reception, and then 5 more times in the morning and afternoon.
A few months' shy of 30 years later we divorced, because she found out that I had been seeing WGs. At the time of my divorce, I had one beautiful escort friend I had been seeing regularly for six years. I invited her over for a 24 hour overnight, ending on the very day that my divorce was final. I told her that I wanted to go 10 rounds to match what I had done with my wife many years earlier... and, of course, that I would give her a huge tip if she succeeded. We came close... We did go 10 rounds, but I could not finish on two of the rounds. I was sore for four days!
Have fun, CGP
P.S. Of course, I gave her the tip! She did her part...
