video and picture of Carly: http://tkpassword.com/7faK I have been dating my girlfriend, Michelle, for about four years and we are both twenty. She has a younger sister who just turned eighteen. Carly is blonde, and has a real nice body with curves in all the right places. Much to the dismay of her sister and the rest of her family she likes to dress like a slut. The only underwear she owns are sexy thongs and boy shorts with sayings on them like “PINK” and “Sure Thing.” She always wears low cut tops that show her C cup cleavage and whenever she’s going out to party she wears really short skirts. Michelle dresses a lot more conservative than that so when I see how her sister dresses it really turns me on. Michelle’s family had a reunion to go to out of town over the weekend. Her parents asked me if I would mind staying at their house that weekend to watch the house and take care of their dog. I agreed and figured it might be fun to go through Carly’s room while everyone is gone and look at her sexy underwear. They were all set to leave when Carly throws a fit because one of her girlfriend’s is having her eighteenth birthday party on Friday night. Yes, Carly can be a real drama queen at times and like usual her parents gave in and let her stay home on the condition I agreed to watch her. They told me to make sure she doesn’t bring any boys home. The rest of the family ended up leaving Friday around noon and they wouldn’t be home until late Sunday. At first I spent most of my ... time watching TV. I didn’t see much of Carly as she spent most of the afternoon in her room with the door closed. Finally, she started to get ready as I heard her going back and forth between the upstairs bathroom and her bedroom. I couldn’t wait to see what she put on because I knew whatever it was it was going to be extra sexy because her parents weren’t there to object to her outfit. When I heard her coming down the stairs I rushed out into the hall pretending I needed to use the bathroom, but I really just wanted to get a good look at her. She was wearing a really short skirt and a top that showed a ton of cleavage. My cock got hard, but I am sure she didn’t notice as she never pays much attention to me. In fact in the past few months she had been unusually short and even somewhat bitchy towards me. I had asked Michelle about it and she just said it was just Carly being Carly and nothing for me to worry about. “Hey, do you need to use the bathroom?” she asked. “Yes, but if you need to use it first I can wait,” I replied. When she went into the downstairs bathroom to give herself a final once over I called the dog over and started petting him. I positioned myself to make sure once she went back upstairs I would get an eye full. She comes out, I kept rubbing the dog and she starts back up the stairs. I am bent down so I can see right up her skirt. I could see her ass and her pussy barely covered by the little black thong she was wearing. I got a huge erection. I went back ...
