It was going to happen.Lindsay grabbed my cock and positioned it. I pushed forward. I felt my cock begin to enter her. As I went deeper, I groaned out.... It felt so good! I pushed all the way in and looked down. Lindsay opened her eyes and smiled up at me."You feel amazing, Lindsay," I complimented."So do you," she said.I instinctively started to thrust going slow at first."Mmmm-ooooh!" she responded.My mind was drenched in the sensations of the simple in-and-out movement. Never had I felt such a. Trying not to look at my still erect prick with cum all over it she handed me the wash cloth. "Here clean yourself up. Get dressed and come downstairs when you are done and ready for dinner." I caught my mom glancing at my cock; she blushed and quickly left without saying another word. I felt oddly satisfied having gotten off in front of my mom. I felt like I lived out one of those incest fantasies’s I read stories about. I went down for dinner and my mom acted like nothing had happened. His dick was still hard as it was poking on my ass hole. He brought his lips near to mine, and gave me a good kiss. I just melted on his body.After a long kiss, he said,”Go now. Day after I will come to your house, and make both of you my bitch”. I was a bit scared, and asked him,”What is your plan? Please dont do it. Please” He slapped me hard, and said,”You are not allowed to ask anything,bitch. You are my property now.Day after tomorrow sister will be my bitch. How i do is upto me. Now go,. The next 10 minutes we both were silent and she was still looking tensed. I took the lead, walked up to her and kept my hand on her shoulder. She immediately looked at me and gave me a weird smile. I went close to her and hugged her for some time and slowly moved my hands behind. She was quiet and did not move then i kissed her in her cheeks and her forehead and finally planted a soft kiss on her lips. Her eyes were closed and she did not give any reaction. Then i started kissing her lips.
