Just as I was riding a new wave of orgasms, I suddenly heard Rob's front door knocking. Only as if in a trance I noticed Rob answering: "Come in, the door is open! What was that like? Did I mishear, or was that even a dream? I couldn't really realize it. And Rob just kept on as if nothing had happened. I sat on his hip and his gorgeous cock stuck completely in my ass and I stretched in this position my naked butt also still exactly in the direction of the apartment door, at which it had just knocked. While I was still thinking about this bizarre situation, suddenly a couple stood in the middle of the room, right next to us. They were both black, too. She was quite a tall, slender and pretty woman. He, on the other hand, was a cop of a guy. "Hey Rob, old man" laughed the young woman and slapped him with a "ghetto fist". "What did you treat yourself to again, oh shit, she has a tail," she cried out questioningly. But Rob just went on as if it were the most normal thing in the world and laughed at the woman: "Yes, it's my first tranny. It doesn't show. But you can fuck the old lady for hours in the ass and mouth. I picked up this little cock-loving married bitch in town the other day. It just takes horny and hard Lia." I just couldn't believe what I had just heard. Although, of course, deep down inside me, I knew how right he was. Lia looked at me searchingly and laughed arrogantly and disdainfully: "So you're the cock girl who indulged herself here Blondie. That one like you even has, like, a man? But apparently, your guy's not doing it. And there you just let our Rob fuck you. That's pretty hard-boiled you little bitch,' she laughed at me with a mean undertone in her voice.
