But there was one time, when I was playing with my pussy, in the comfort of my bed, when our little secret started. I had a yellow vibrator that made my lonely days full of orgasms, and it was jammed in my cunt when I noticed that the door from my room, which was open by a crack, moved a little.“Peter, is that you? Don’t be shy. Come on in!” I told him with a really sexy voice.And he entered the room, just to see that he was naked from the bottom down, because he was jerking of, watching me playing with my toy. He was blushing like a lobster and I told him to come closer and sit on the bed.
