Eventually she had taken his full length, her eyes was tightly closed, she had gasped several times as she took it and I think she had held her breath...at times. But now she was comfortable and started to really enjoy it. I watched amazed as she gently moved up and down, side to side and even a circling motion. She leaned forwards getting full contact with her clit on his pubic bone. Her movements were fairly small but it appeared very effective, she was really enjoying his cock and knew how to. The red brick facades hide the pain and suffering to most in the daylight. Dimly lit windows look like small eyes staring balefully down on her. This is not a place for a sexy lady to be out wandering in the dark. As she turns the corner onto a smaller alley a large rugged black man slips from a shadowed doorway. She walks slower now as if frightened by where she is still lost in thought. The man is dressed like a thug as he follows her slowly. Baggy khakis and a white tee shirt covered. You begin to stroke yourself slowly, delighting in the erotic pleasure being offered to you. I begin to slide the head of the enormous dildo inside you, slowly teasing your cunt with the head of the toy, moving it in and out of you only and inch at a time. With my now free hand I slide it beneath you and start to probe your beautiful, hot ass with a finger soaking with lube. I slowly begin to press a finger in and out of you. After a few minutes, I force in a second, causing you to flinch. Easy enough, I thought and when I knocked, she opened it and calmly took it and put it on then thanked me as she walked down the hall to her room.There continued to be instances like that, I just always thought that she looked at me, her older brother, as someone other than a male, a guy, like maybe I was more an inert fixture around the house. What did I know?So, it was summer, our parents were off to a weekend at some friend's lake cabin, I was in charge, now being seventeen and driving, of.
