She happily went on her fours. I took a moment to appreciate her from behind. Her awesome ass. Her nice curved back.Her jet black hair which was now m...essed up because of sex. It looked amazing. She looked behind and said, ” C’mon! Fuck me with that big dick!”I smiled and held her buttocks. They were so soft and firm. I spanked her twice and made her yelp with pain. She giggled and said, “Oooh that hurts! But don’t stop!” I laughed and rammed my duck into her wet pussy! “OH FUCK!!! ” She. Although we suspect we know exactly what a slut like you wants to do with it.====And that was all. She was free. Her blackmail was over. She could be a normal girl again.Except she couldn't, could she? She felt anxiety and stress rise inside her. She lowered her hand to her cunt and started to rub it. Masturbating always helped when she had bad thoughts. It made her happy. She was still pregnant with her brother's child. And she had agreed to be his fucktoy and his porn model to pay. Then she smiled and said, ek baar karake dekho. Can you do it once again? Then again I hugged her tight and gave her a lovely kiss. She said, feels good. Then I asked her, can I do this daily to you. She said fine. So this is how our incest journey began.Since we were sleeping together in the night, it was full privacy for us at the night as well as no one was at home during day time also. So we started kissing each other. Then we started kissing nude. Finally one day I broke her virginity too.. I put my hands at her waist, kissed her neck again, and started sliding my hands around until I found her hands. I grabbed hold of them with a firm grip and maneuvered them behind her back; I grabbed my tie and tied her hands together. Not to tight of a knot, just enough so she knew she wasn't going anywhere. "And just what do you think your doing?" she asked with a grin on her face. Without a word I kissed her and slid my hand into her sweatpants. I found a pleasant surprise, she wasn't.
