I could also sometimes hear the bed creaking. I completely knew my dirty fetish was wrong. But I just could not stop myself. I really wanted to see my... dad fuck my mom.And so, on a day they had gone to attend a function, late evening, I decided to set up a camera and mic inside their room. I choose to fix it on top of the TV in their room, as it was directly opposite the bed and guaranteed a great view of the whole room.My dad and mom were both 40 years old. They had a love marriage 20 years ago. I'd never known them have much in the way of secrets from one another. I wondered what Dad thought about it. I guessed it probably turned him on as well! I tried to imagine him with an erection - not something I'd ever thought about much before - but I couldn't really. I'd seen him naked often enough in the past, but never like that.It was quite soon after that I heard the first familiar sounds from their bedroom. The odd murmurs, then a little gasp here and there. Then some laughter, and more. Slowly she adjusted to the light, but as she opened her eyes, she began to feel her predicament. Her wrists were bound behind her, so tightly that her shoulders were feeling strained. She was on her knees, on dirt. She glanced over her shoulder, quickly noticing that her wrists were roped and the rope was around a thick pole, possibly the centre beam of a tent or lodge. She tugged instinctively on the bindings but winced loudly and squeezed her eyes shut. Her wrists felt as if they were broken. I made myself stop thinking about it so I could sleep. ************** The next morning I woke up thinking I need to start finding a way to let mom know I had a boyfriend. I wasnt even really sure if she would allow it, I know she didnt let Sherri have one for a long time but there had to be a way for me. I decided to ask permission to go to the mall and I decided to try to get mom or Sherri to drive me rather then bringing up Scott taking me. At breakfast I brought it up and mom was hesitant at.
