I went with my mother and my step-father for a Summer vacancies, I didn't wanted but my mother made me go. The first few days, I don't know if it was because of the heat or something else, my mother had headaches and didn't want to leave the hotel so I ended up going alone with my step-father swimming, lunch and sightseeing. It was during a sightseeing that I ended up having sex with my step-father. Unfortunately the day after this my mother got better and we never had a chance to do it again.
