I could see from my mom's face that she is getting some kind of immense pleasure out of it. She was moaning as "Aah, yaaaah, mmm…" I couldn't unders...and what to do as I was getting aroused too. Then I found dad coming out of mom's groin and undressing her. I was so scared of my own arousal that I ran to the toilet and jacked off. As I was returning I heard sounds like..Thup…Thup from their room and heard both mom and dad moaning.After a few days dad told us that our grandpa and grandma are. I can’t really describe it but it kind of feels like a painful electric shock. I think I screamed, but he laughed and just kept fucking me. Guys kept slapping my boobs and my tummy and my thighs hard and fucking me really hard and fast. My body built up one last huge, earth-shaking orgasm and I screamed and shook with it. I heard my owner laugh and say see, I told you the bitch is a total fuck pig. I have no idea how long I was there getting bred, or how many guys fucked me, but my cunt had so. Then, my sister asked a question that seemed so profound, that I never would have thought of asking anyone else. “Do you masturbate?” she asked. I was shocked as I should have been, but I was unable to respond for a minute. The fact that my little sister knew what this was and was asking me about it. The next thing I said did not answer her question, but it seemed to thrive the conversation. I said, “Where did you learned something like that?” “A few friends at school told me about it,” she. “JERK!” she exclaimed, “I’ll get you for that!”I dialed the house in Hyde Park, and talked to Jessica and Kara, telling them I loved them and that I’d call again on Friday evening. When I hung up, I went back to sit with Katy.“That was low, even for you!” she grinned.We talked, ate popcorn, drank, and listened to music until bedtime.“Where are you sleeping?” she asked.“You tell me.”“Come to bed with me.”I nodded. We undressed and climbed into her bed. She snuggled close, but didn’t kiss me, so.
