As I was cleaning the house of a friend, the son of the housekeeper came into the room and started to watch me. He seemed to be very interested in my body and was staring at me while I was changing. I didn't mind it at first, but after a while he started to touch himself while watching me. I was a bit surprised, but I didn't mind it. He is just a young guy and I think it's normal for him to get aroused by a pretty girl. I continued to clean the house and he continued to jerk off. It was quite funny to watch him, because he was really excited and he was not able to control himself. I think it's a nice story to tell, and I would definitely recommend it to anyone who likes erotic and funny stories.
