This happened quite a few years ago, when I was 14. I always loved being home alone, but this time it was different. Once my parents left, and after waiting about ten minutes to make sure they wouldn't come back for something they forgot, I got right to work.
My parents always lock the door to their room before they leave, so that told me something was in there, so I immediatly tried to find ways to get in. I finally thought of our laundry chute, so I climbed in and crawled into their room.
Once in there, I started looking around. When I looked in my dad's nightstand I found some porno. I kept looking and found a box of condoms, which I heard work really well to masturbate with. That night I think I jacked off more than any other night before.
It was very exciting being in my parent's room, not knowing when they would get back and maybe catch me. Ever since then, I climbed through that chute and watched those pornos hundreds of times.
