They got in Sylvia's lemon yellow Geo and pulled out of the parking lot just as a police car pulled in. Henry looked nervous, Sylvia just looked angr.... She was positive Henry was innocent, and those asshole detectives were looking to pin this on him. It was the easy way out for them. She made a call on her cell phone, and confirmed that they'd come back for Henry. They were pissed because they'd just missed him, and they were camping in the office until he showed up again. Sylvia digested. I start to think about scenarios that could happen this weekend,including me and my sister and lots of groping. This as usual gets me off in about 2 minutes. I masturbate every day, because I'm almost always horny when I'm with my sister, for obvious reasons.While I'm cleaning up, I hear a faint knock on the bathroom door. I immediately take in a breath.I hear my sister's voice, "Hey, Charles, what was that noise? I hear something that sounded like..... pain." Damnit. My sister had heard me. This continued for sometime and now I was about to explode if I didn’t have any sex.I started to stare at her when she was not watching and used to slowly rub myself. This continued for some more time. One day when I came home in afternoon I saw her sleeping in the bedroom. She was wearing a sari and blouse and from sideways sleeping position her navel and stomach area was visible. She was like fleshy and milky white from inside with enough fat in places to make her very sexy and erotically. "Could you lay that shirt next to the sink," she called over the din of the running water and through the crack in the door.I answered, "Yes," and peeked into the foggy bathroom. I reached in the crack of the door and extended my arm to lay the folded white t-shirt next to the sink. I couldn't help but stare through the fogged up translucent glass at the figure in front of me. I could see the outline of her tits bounce as she washed her hair and then listened as she hummed a tune and washed.
