In all the overnight sessions I have done and they number in the dozens over the last decade, to set an arbitrary time period, I have only had one provider who came 4 times, and that was in two different sessions.
Once before dinner, another in the evening before bed, in the middle of the of the night and then on waking up. I have seen him since but only for short sessions. He always cums in those too.
He’s around 30 now so going back to our first date he was around 23 or 24.
Youth is a wonderful thing.
