My hairy skipped a beat. I was scared, what if she tells dad about it. Mom was sleeping in the next room, I called her out, but I guess she was fast a...sleep, she did not respond. I went to her room. She was sleeping there in her sari. The pallu was down & the cleavage was clearly visible. I again had a hard on. However, dad was waiting on the call. I placed my hand on her shoulder & shock her. She woke up & looked at me with surprise; our eyes must have been locked for about 2-3 seconds. I was. I was still tied up."Tracey, did you want me to eat your pussy? I came a little fast, so Idon't think you got an orgasm?" I said."No, It was great, and I did have one," Tracey said.Terri looked at me. "I need to know, do you love us?"I looked at her earnestly. "Yes, I've loved you both like my own familysince we were 7." No, I mean do you LOVE us? Would you marry and live with us if wewere old enough?" Terri asked."Yes, without hesitation," I replied."And you wouldn't do anything to hurt us?". “I would prefer she repeat back what she understands. Feel free to zap your sister if you aren’t sure she truly understands,” Dad said. He told Taffy to expect to be zapped after she answers me and to assume she must be more explicit in her speech. He zapped her as an example.“Yes sir, I understand,” Taffy said as she put her hands on her crotch.Dad zapped her again much more intensely and told her not to touch herself without permission. He told her to try again.“Yes, sir, I understand. I will. I reach over and move my sister's thong as she spreads her legs. Her pussy is getting wet with no signs of that changing. I finger her and not long after she's fucking my two fingers as hard as she can trying to contain her moans. I silently jump in front of her and kiss her to mute the noise while pulling my fingers in her pussy ferociously. She comes hard and lets out a quiet growl in her throat.She regains her composure and sits me back down in my seat. Turning to me she straightens my cock.
