The first time with my holiday acquaintance

I bumped into my holiday acquaintance from last year while out shopping and simply arranged to go on a spontaneous weekend trip. After he had just told me that he hadn't had sex for over half a year, I suggested that we find a quiet spot in the forest to spontaneously end this "dry spell". Sex in the open air is so much hotter and I was so excited to be the first for him again after such a long time in the car on the way there. When we got there, we got started straight away and after a short time he needed a break. But no problem, in the meantime I just carry on on my own. But the recovery break doesn't last long, so I'm soon able to let another hard stud between my thighs. I wanted to see what cum I'd managed to accumulate in such a long time anyway and tell him to wank his hot juice into my hands at the end to check. A lot of cum came, but do you think he was fibbing to me? How much do you cum after such abstinence?
