I could easily hear loud moans. That view was really enjoyable and I was watching their fuck session for 15 minutes.Then, after cumming, they both dressed up. I rushed toward the main door and rang the bell. She came to open the door and I said –Me: I forgot to give you the number.Then she took my number. "I want you to get wet so I can slide in."
