It was when my father turned and raised a hand to strike her, but I think he realized that he would do something he may regret so he screamed at her t... mind her own business which frightened my younger sister Elizabeth who went running to her room crying. I stood there shocked and horrified and didn’t know what I should do. I did the first thing that came to mind which was go after Elizabeth. I wrapped her up in a hug and not knowing myself I told her that everything will be fine and that no. I took this time to make a run for it but he grabbed me and threw me back on the bed.He was fully naked and I only had my thong still on. He got on his knees and pried my legs apart."Daddy please don't do thi- uhhhhhhhhhh"I moaned when his tongues came in contact with my clit. I've never felt anything this powerful like this. The little energy I had left I used it to try and push his off of me but I couldn't.He started sucking on my clit and I went crazy.Next thing I knew I was pulling his face. ‘One’ Sarah gasped.‘Two’ she said again as I smacked her again, this time across her left buttock.I kept going, wondering if she would use our safe word. I spanked her buttocks as she counted the blows. She was getting rather breathless now and I knew she was getting really turned on. I got to a count of 20 and decided it was time to up the ante.‘Get up Sarah. We need to go on to the next phase of the punishment’Sarah stood up looking a little shaky. Her face was red from bending over my knee. “Okay?” I whispered. “Okay,” she said, standing up. In four steps we were behind the door, in my bedroom with its large, comfortable old bed. We embraced, full body, and kissed, and I slid the flimsy dress over Lin’s head. She was wearing a thong and a bulky bra. I unhooked the bra and massaged what there was to massage. Her nipples were firm and eager, so I laid her on the bed and kissed and sucked them. Then I headed down her body to crotch level and extricated her thong from its hiding.
