Young Tina had a reputation even at age sixteen of being a wild young thing and I was to soon find out how wild she was. Our c***dren attended a show ...hoir at least once a week as they both loved singing and my daughter,s voice is truly incredible and was even at age seven and Tina knew this. One evening shortly after Sarah drove the k**s to rehearsals where she,d stay to listen and offer her support for about three hours while Inusually stayed home tidying up and watching telly. Not long after. We watched for another 3 hours and my balls and cock were straining to get out and cum so bad! We had now watched everything from gay to shemale to DP, lesbian, pretty much everything. We hadn't said much during it other then how hot she was or if the dudes in the scene were good looking. I asked him if I was allowed to go p*&^ and he said well what about you touching yourself. I said well I guess you have to watch to see if I do anything outside of the normal. He said fair enough so we. By the time I had it all, tears were rolling down my face, and I knew what the girls felt when we did this to them. After getting used to it, the dildo started going in and out real slow. Once the pain subsided, I put Shane’s cock back in my mouth. Brenda then came and sat on his face. A few minutes later, I felt someone get under me, and start sucking my cock. Getting fucked in the ass, having a blowjob given to me, and then sucking my own brother off got to me, and I was soon moving the cock. I went to bathroom and left the door lightly open as if I forgot to lock the door and then I made myself nude and my dick got erected fully. There is some gap as door was slightly open. I made a action like masturbating so that my dick can be visible from outside.As I expected, my cousin sister was walking to bathroom, she was stunned watching my dick and actions through the door opening. She was watching what I ‘m doing. I pulled up the foreskin of my dick. She was hot now seeing my erected.
