It was a typical Tuesday afternoon. I slept late, woke up, ate food and went back to my room for a while. It wasnt until later that the real fun began.

My mom was out at the bar down the street with her boyfriend and i knew in the back of my head that she wasnt coming home tonight, my sister Cristine at a friend’s house, and my sister Megan retreated into her room like most 17 years olds are on weeknights. I was basically home alone. It was half past nine and I was bored out of my mind as I watched TV.

I heard my sister Morgan through the walls on the phone with her friend. I was bored, why not listen in? She would never notice. I went up against the wall, and turned my TV off as i tried to listen close. I heard muffled voices, and only one side of the conversation, but it went like this:

“He was really nice, though, he even texted me the next morning… I know, but at least it wasnt just a one night stand… No, i actually wasnt drunk… I dont think so… he was about 5 inches, not my biggest yet… Oh really? Damnit, okay. Well, I’ll talk to you later… Yeah i’ll tell you if he texts me… Okay bye Jenny”

I quickly backed off the wall, laid down on my bed, and turned my TV back on in one fluid motion, smiling to myself as I reviewed the conversation in my head. It never occured to me that my sister was having sex! I never put much thought into it, but it made sense. She never had a steady boyfriend, but she has long nights out sometimes. I tried to put the thought away but it kept haunting me.

Now, my sister Megan wasn’t the head-turning, dick-hardening, jaw-dropping girl that you stare at all the time. But she had a nice body. She was kind of short compared to me, about 5 foot 4, a bit longer then shoulder length dirty blonde hair, A nice build because she was a cross country runner, 34C breasts, and a nice, full ass.
