It was non-stop, like as soon as one pulled out the next was ready to go again. And I made it pretty clear that what I wanted was for them to use my hole and not worry about me - focus on pounding my ass to get your nut and leave it at that. Work all the travel stress out on me. That sort of thing. And it was really only 3 incredibly horny Scotsmen who came 2-4 times each. I really just considered it part of what I was asked to do - show then a good time, help then relax, etc.
They were super into that too, but also considerate. They were really comfortable with just taking their time and enjoy it, holding my legs up/back so I could relax and their buddy could go to town until he unloaded, etc.
Seriously best time ever.
