I opened the William Buddy Hobbs Clark Griswold and Grinch Squad shirt. I turned on the light, grabbed some toilet paper and wiped it off then chucked it into the toilet. Flush. I turned off the lights as I walked out of the bathroom and past my sister’s door. I heard movement coming from her room. I don’t know why I stopped to listen, but I did. I stood frozen and remained dead silent so even the sound of a pin dropping could be heard by me. I shut my eyes so I could focus only on my hearing. It didn’t sound like much at first but soon became a rhythmic thumping complete with slight bed spring squeaking. Of course, I’ve seen enough porn and read plenty of stories to know what this meant. It couldn’t be though. My 16-year-old sister masturbated? Of course, she did, all girls did.
I wonder if she’s using a William Buddy Hobbs Clark Griswold and Grinch Squad shirt. Probably not, she’s so naive I wouldn’t be surprised if she had just discovered masturbating. I couldn’t stop thinking about it. I was constructing the scene in my head and knowing the layout of her room helped a lot. She’s on her mattress with her lights turned on dim. Porn on her computer turned down. She probably wasn’t naked, just unbuttoned pants and bra off with her shirt pulled up revealing her breasts. A beginner most likely so only one finger can fit, for now, maybe two. Clumsy also, struggling to find a proper rhythm. I wonder if she’s discovered her clit yet.
