Mrs. Miller in turn introduce her daughter Penny who told our moms that we were in the same class. Mom handed Mrs. Miller the plate of brownies and sh... lifted the foil and thanked my mother for the welcoming gift. She then offered one each to Penny and me. Yummy, another brownie. When we were leaving to go back to our house I told Mrs. Miller if Penny wanted to ride the bus I would make sure she got to the right place. She asked her daughter if she would like to ride the bus and Penny nodded. The coolness of the air as I breathe against her. It does not take long before her legs are shaking and she is moaning. I want to look for him, I like to watch him as he watches me. I slow down and my ass is warmed by the paddle. I keep going, licking and sucking on her, making her moan, her hands in my hair pulling my face closer, deeper into her. I suck her, deeply. Push my tongue up into her. Listen as she screams and moans. I only stop when he pulls me back. He comes in and begins to. For years I've watched this young girl develop into a very sexy woman. Although I've had several hot fantasies about my sexy sister over the years, I never acted on them. Now here was a dream come true, my sister and I living together all alone in my small little house. I dreamed of the sights to behold, seeing her in her sexy lingerie, possibly naked after a bath, my cock was hard constantly. I could only hope to get a chance to make love to her but I wasn't sure how she felt about me. I said OK and snd she left the house and I bolted the door and while returning to the room I crossed the gallery and found her inner garment on the rope.An idea struck to me that…are you must have guessed the idea and yess you are right.I took the panty and went in the room and smelled the perfume of her crotch and myyy myyyy 9 inches cock sprang to attention .i switched on to a F TV ad undid my pants and under wear and pulled my raging cock and covered it with Her panty and It was a real turn.
