Once my plaything had finished, Gore again held the chair back, assisting her to rise and approach me. I too stood, stepping forward to meet her. "Thi...s way, your chair awaits." I guided my girl to a comfortably padded straight backed chair. "Sit." Once seated, I attached the wide cuff-like velcro pads that secured her ankles and wrists to the chairs legs and arms. "Sit back," my plaything's head now rested in the sculpted padding of the head-rest, a short chain attached to her collar,. After some five minutes, I woke up my brother, and we went to our parent’s bedroom. There was a small gap in the door, through which we could see inside the room clearly. Lights were on and Mom was sitting in Dad’s lap, and kissing each other. Slowly Dad untied Mom’s nightdress, and she helped to remove it off. She was not wearing any undergarments, and there she was sitting in Dad’s lap, stark naked like a Venus statue! Even at 40, she was really beautiful, with large firm round boobs, big. You want her. What’s wrong with that?Legalisms didn’t bother me. I had convinced myself that what was happening between Vi and I wasn’t incest. Not really. Violet was my half-sister, and we’d grown up apart for most of our lives. The doubt that had hooked its barb into me was entirely about what was best for her.She was right. I thought and obsessed about things far too much. But I loved my sister, and I knew how volatile her past relationships had been. I wanted sex. My entire body yearned for. She pressed her finger in the sphincter and let it slide in up to the knuckle causing Clara to flinch and groan. She removed her finger and then she spat into the anus allowing her saliva to moisten it further. Dora dipped her tongue back into the bung hole and Clara almost came again with the eroticism of the moment. She alternated between eating Clara’s ass and finger fucking it. Her fingers now slid easily in and out of Clara’s hot asshole. Alberto had told Dora how much that Clara had.
