The first ten, less than three minutes. Closer to two minutes.
The remaining, I spread out over 10 minutes. Those could have been in quicker succession, but I had a woman faint once after 20,
so I took it a little easier on this one. She fell right to sleep after I stopped.
The next morning when she crawled out of the bed, her legs buckled from under her. She laid there and said, "Oh, you bitch!"
But, the next night, she wanted more. On that, I decided I wasn't such a bitch, just very accommodating.
