I felt myself begin to pump. The pulsing flow of probably more than quarter of a pint of thick gooey semen paste began to thunder up my shaft. I thr...st as deep as I could as it reached my glanse, as the explosive release of that first gush sprang out of my dick Olga began to howl. Her body stiffened. Every muscle rigid, her grip on my balls tightened and the excruciating pain forced more power behind the exploding semen. The thick goo squoze paste my glanse and oozed back between my dick. I am intense. Cathy was frantic.”I had thought the same thing. I wondered if Uncle Bert had programmed her to be this way, or, if there was a conflict between Cathy’s nature and the programming. I wondered if Dad knew and that was the reason he and Uncle Bert fought over Cathy. I hated to think Uncle Bert had done something like this to my sister intentionally. Had the devil dog bit him? Was that the reason he was putting me through so much before I got the formula?“Are you all right?”I looked. I looked over and saw his Balls hanging out of them. Damn I thought, I wonder if he knows. Oh well, I liked the peep show. I thought I would brake the ice and asked him, "Do you come out here a lot or is this your first time here?" He said, "No, this is my first time here. I saw you walking down this way and thought I would follow you." Oh Hell, he saw me walking in my underwear with my Cock hanging out. Now what to say. So I looked at him, his Balls hanging out so nice and plump. I could now. I went to hall and was waiting for her. She came in a sexy red and black flowered nighty. She was looking too good in it. Thought of hugging her there itself, but anyhow controlled myself.She came and sat nex to me on sofa and started seeing tv with me. We started casual talks generally and after some time I said sorry for being in room and seeing her in that state. She said then you should even be sorry for peeping into my nighty to see my boobs daily morning also. I was in utter shy and told.
