Revenge on my sister

I still get a smirk when I think back about what happened that summer.

My name is Tom and the story I am about to tell happened back when I had just finished high school.
I lived with my mom and sister (two years older) in a small house in Southern Indiana.
My dad had divorced my mom and moved out West with his new wife a couple of years ago.

Things were pretty normal overall. I went to school and had just started a part-time job.
My time off was spent with friends, looking for a girlfriend and homework.
When Summertime hit, everything was better.

I spent my non-working times hanging out with friends or watching TV, or just normal guy stuff.
From time to time, my friends and I would happen across a Playboy or Penthouse and it would magically appear in my room.

It just happen to be one of those times while I was enjoying a centerfold with my dick in hand that my sister barged in to my room.

“Do you have…” she started.
I tried to cover up as quickly as I could, but it was too late.
“Really? You’re jerking off? You know mom’s going to be pissed about that magazine.”
And with that she walked out.
I felt my face red and my dick deflating quickly.
I put the magazine back in my nightstand and left the house. I really didn’t feel like seeing my sister after she caught me.

That evening, somehow my mom found out about my magazine. She made me give it to her and she tossed it out with the trash.
Just as expected my mom was not happy about having porn in her house and grounded me for 2 weeks.
Personally, I felt that was a lot excessive! I was now pissed myself, not at my mom, but at my sister.

The next day I woke up still angry. I knew I had to find a way to get back at my sister, but I wasn’t sure what I was going to do yet. I spent the morning watching TV, since I couldn’t leave the house. My sister didn’t seem like she was going to apologize or anything, but just went about her normal day. She took her shower and called her friends. I heard her making plans for later that day.
