I went to her and placed my hand on her shoulder. She startled and started to beg me not to tell this to her hubby and also to the owner of the house(...my mom). She was begging like hell and I said ok. But with a condition that i’m going to have sex with her. She got shocked with that first and then she said that she’s on her periods from today and told me to come after 5 days.I said ok but I need to masturbate now. She said do it in your room. I asked her to help me out and she said to come to. I got it in a bathroom in a club. It would have to do. I found it in my nightstand drawer and handed it to her. She opened the packet and unrolled it over my cock, looking lazily at it and stroking it once or twice before rolling it down. If she was nervous about being penetrated by it, she didn’t show it.I opened her legs and lay on top of her, guiding the tip of my cock between her legs. It was so tight nothing came easy, but she was also very wet, and with time I was halfway inside. “I kissed you as well. I really liked it, and I wanted to do that. To be honest dear brother, I want to do more.” I went to speak but she cut me off saying, “I know we are brother and sister and we shouldn't but, I want to. I have always loved you. I have always trusted you with everything in my life. You are the only one in my life that has always been there. That has always loved me no matter what happens. I want you, my loving brother, to take my virginity. I am ready to do this. I love you. She leaded me back to the master bathroom and there wasn’t anything wrong. I turn around and said, “Did you fix this or did you shut off the water?”She replied, “Well I knew if I said this you would rush over and then this is a perfect excuse for everyone if they ask why you were here in the middle of the day.”“Oh yea”, as I flash a devilish grin and feel my cock growing in my pants.While slowly walking toward me and unbuttoning her blouse, “Yea and I feel really bad about how I left you in.
