I hollered up that I was gonna do laundry but I didn’t get a replied I figured she was sleeping since she’s a nurse and does the night shift. So I went into the laundry room which is below where her room is and has a few vents. I could here her moaning, I didn’t know what was up but decided to listen more that’s when I realized she was with a guy. I put my phone up to the vent. As he left I looked out a window and noticed it was the black guy from across the street whose married to this real heavy set lady. I went upstairs and told her I was gonna do laundry, she asked me if I was in the laundry room (as it’s obvious to anyone whose been in our house that you can hear what goes on in the rooms from there) I said no I just got here ...
