My parents were at work and no one else lives here so I decided it was safe to masterbate. I was going for a good little while and I had my door open because I didn't think it would matter. Little did I know our cleaning lady was there. She walked in and I didn't know what to do so I just stopped and looked at her with my d*** rock hard and ready to burst. She just chuckled and said I didn't know anyone could be smaller than my 13 year old. She then told me to finish and she left my room.
