My name is Marc, I’m 17 years old, and have a younger sister Lindsay who is 13. I know it is wrong but i have always thought of her as more of a sister because she has such a nice body. I have masturbated thinking of her many times, and have had to stop myself from going even further several times.

I got home from school on a thursday afternoo and collapsed on the couch to take a nap. I woke up around 6 to have dinner, when my mom told me that she and my dad were going to Toronto for the weekend, and I would have to look after my little sister lindsay for the weekend. I didn’t really mind because I had alot of homework to get done, and didn’t really have time to hang out with my friends.

When i got home from school on friday, I went up to my room to masturbate thinking of Lindsay before she got home. I took a quick shower and than started with my homework. I was at my desk when Lindsay walked in, and she sat down on my bed, and we talked while I did my homework. All of a sudden she was quiet, and I turned around and saw that she had found my stash of booze. She picked up a bottle of vodka, and looked at me, waiting for a response, but I didn’t know what to say. Then what she said next shocked me the most.

“I didn’t know you drank Marc, we should get drunk tonight and watch some movies!”

All I could do was nod my head, and then Lindsay skipped out of my room which gave me a good look at her tight ass.
