If you book me for full night, does it means, that we have full night sex?

The simple answer is no. Considering that I am human and not a sex machine, then booking length does not define how much sex we have.

Anything intimate depends on feelings and chemistry. It can't be measured with the time. If we feel good together, it can be possible multiple times or if you treat me like a whore, then sex will not be possible at all. Remember, that you book my time. I offer quality over quantity!
