I screamed out and then he stopped again.I finally yelled at him " god damn it Doug. What are you doing? That's the second time you had me ready to cu... and stopped."He said " I know that is my intent. Marg loved it when I did that and I promised you a great orgasm and that is what I am going to give you."With that said he told get on my hands and knees on the bed. I did and Doug shoved his cock in my cunt from behind hard. He slapped my ass then pushed his finger in my asshole while fucking me. We are both fascinated by the huge size of the stallion’s cock. As we watch in awe, the stallion, with the help of men, finally finds his way and sinks his cock slowly into the mare’s belly. My mother seems very excited and is rubbing her thighs together. I ask her if inbreeding is desirable among horses, why not between people? She does not know the right answer and only tells me that society frowns at such matings.Then my mother tells me that this is more of a sociological than biological. The girlfriend knew this about me, and planned a little scenario for me. My girlfriend was living on her own at the time. She worked a 9 to 5 job and would often go have a drink straight after work, prior to going home to her apartment. It seemed that she asked Aaron from work if he wanted to join her once. I met up with her, and joined them both that afternoon. We all sat at the bar and had a few beers together, stayed a few hours and then all walked out together to leave. I drove away as did. I have been staring at you past 3 years. You have such amazing body that I could not control myself. I crave for you. I fantasize for you. But I am wrong person for you. I do not deserve you. I felt that I melt hearing all words from my father.Now it is my turn to devote myself to papa. In second I took off my clothes and I was full naked. I told to papa, now you can make me yourself. I will be always yours. I will take care of you. He took my nipple in mouth and started sucking. I was moaning.
