I was over the weekend visiting my s***er. Since a hot shower I treated myself. When I went back to my room, I saw him. My s***er's boyfriend, as he sniffs at one of my panties. He was embarrassed totally at once and was ashamed. However, I was damn cool, and because only he was there, I made clear to him that if my desire is not satisfied, my s***er learns of them. He agreed, so began to put on his face.
