When I was born my Dad was only 19 yo, he never got married with my mom and I consider my step-father my real dad. We always kept contact and some times I went to visit my dad during Summer. I'm 25 yo now, I'm going to marry and my father invited me and my fiancΓ© to spend a few days with him at the beach. A few years back I had sex several times with my dad and I thought it was completely over but I guess not. I was about to leave the hotel to meet my boyfriend at the beach when my Dad enters my room, and then this happens. When he finished I didn't had any strength to leave the bed.
