One night my sister came back home late from clubbing with friends. When i walked in the living room, I saw my sister passed out on the sofa.

She had a skirt on and from the position i was standing, I could see her white lacey thongs and the bottom of her ass cheeks. My cock went all hard and I moved closer. I can see her cleavage because of her low cut top. She didn't have a bra on.

I got so horny I grabbed the lube and started masturbating. I moved behind her so I could see her ass. She looked wasted so I slowly lifted the top of her skirt up so I could see all her ass. I was so scared when I lift her skirt, that I started shaking a little. I can't believe I was masturbating over my wasted sister but I was too excited at the time. At one point, I moved my face really close, I could see her pussy through her thongs. As I got more horny, I also wanted to see her tits, so I pulled down her top abit and made it abit loose so I could see them from the right angle.

Before I came, I put my face behind her ass, where I can see her pussy through her thong. My cock felt so good because the taboo added to the excitement. The last few mins felt good and I got really brave and decided to slowly move the bit covering her pussy. I started masturbating harder as I stared into her pussy. I then grabbed the tissue near me and I started cumming into it. The rush of masturbating over my drunk sister got me so horny that I haven't came like that in a while.

Well thats my confession. She didn't find out either and nobody knew or I would of been in trouble by now.
