For me ... it depends on the person.

If the built up chemistry has been incredibly long ... then I tend to shoot very quickly. Or like a super super hot girl that I never imagined ... like pretty face slim waist huge natural boobs ... then its bye bye for me.

Another factor would be when was the last time I came. So if I could prepare in advance ... I would try to cum in the morning if I know that day will be a big event.
