His sister likes humping her pillow - and he likes to watch!


I've got a cute sister that likes to masturbate. No, make that LOVES to masturbate! Seems like every time she's alone in her room, she's laying on her bed fingering herself, or humping a pillow.

I noticed her "habit" a couple of years ago. At first, I felt weird even knowing my sister touched herself.

Then one night when my mom was on a date (she and my dad divorced a couple of years ago) I caught a glimpse of my sister in the bathroom, using her hairbrush between her legs.

I couldn't see her pussy, but I could see she was using the handle of the brush as a cock, pushing it in and out with one hand, while touching her clit with the other.

She wasn't aware the door was slightly open, or didn't know I was home. She was taking a bath, and had her legs spread over the end of the tub, while her head was tipped back against the other wall.

I stopped to look, and it sort of creeped me out at first. I've never had any urges toward my sister (and still don't, just so you know I'm no perv!) but it wasn't long before my curiosity became unbearable.

She's usually pretty careful about her privacy, and up til then, I didn't spy on her. She always had the door to her bedroom closed, but she wasn't supposed to lock it, because we worried about escaping in a fire. (However, whenever mom has a boyfriend over, she always lock her door. I can hear her fucking, but that's another story...)

I noticed whenever mom was at work in the evenings, or out with friends, I often heard my sister lock her bedroom door. Then, half-hour later, she'd unlock it, and come out to watch TV or finish the dishes. I figured it was these times when she jilled off.

Getting a look at her tickling her bean wasn't going to be easy. She kept her bedroom door closed tight. We lived in an apartment on the second floor, and there was no way I could peer into her bedroom window. I thought about getting a spy camera, but I couldn't afford one, and besides she'd eventually discover it.

I then remembered the air vent against the wall between our rooms. I got a stepladder, unscrewed the vent covering, and realized her vent was just on the other side, inches away! With the help of a small mirror, I could see her entire room, especially her bed.

I unscrewed my vent cover ahead of time, so she wouldn't hear me messing with it. I then carefully propped it back into place, then hid the stepladder in the corner of my room. I was all set...

Unfortunately, that night my mom stayed home, and my sister didn't go into her bedroom until it was time for bed.

But the next night mom went out with friends from the office to see a movie. After watching some TV, my sister got up and went into her room. I could hear the "click" of her door being locked.

I dashed into my bedroom, got the stepladder. I carefully lifted the vent cover off and angled the mirror just right so I could see everything. There was my sister, sitting at her dresser, brushing her hair. She was chatting on the phone with a boyfriend, and occasionally would stop to tweak a nipple, or rub her thighs.

I figured maybe she wouldn't play with herself after all. She was just talking on the phone. When I was about to give up, she ended the call, and got her laptop. She went over to the bed, and layed down on her tummy. She fiddled with her computer for a while, I guess surfing for something. I could hear sounds from the laptop's speaker, but I couldn't make anything out.

She must have found something she really liked, because she reached down and slowly pulled down her sweat pants. She just peeled them off, keeping her socks and top on, and never taking her eyes off the screen.

She had no panties on underneath, and I could see her pussy was completely hairless. I didn't know she did that! Just a pink slit that lead to her vagina, and at the top of the slit, a pointy hard clitoris that I could see was poking straight out, demanding to be touched.

My sister then put a pillow under her hips, and started a slow side-to-side, and back-and-forth grinding motion. She kept her eyes glued to the screen, only occasionally using one hand to reach under and do some extra fingering.

I watched her butt jiggling up and down. Her ass cheeks were round and tight, and clenched every time she dug her pubic bone into the pillow. I wondered if her boyfriend was allowed to squeeze those soft cheeks now and then.

After maybe 10 minutes of rocking and rolling, my sister put down the lid to the laptop, and pushed it away. She continued the pillow humping with her eyes screwed shut. She moved faster and faster, her legs moving further apart, giving me a real good look at her cunt hole, which was glistening from her juices.

Finally her legs snapped back together, and she let out a single orgasmic squeak.

Her hips stopped moving, and within seconds, she got off the bed, put her pants back on, and headed out of her bedroom. I barely had time to replace the vent cover and hide the ladder before she knocked on my door and opened it. She said, "Come on, let's finish up before mom gets home."

Just as she was about to turn to leave, she looked down and saw I had a HUGE erection! I was so embarrassed. She just smiled, shook her head, and went out the door!

I finally told a friend about seeing my sister masturbate, and he's begging me to let him spy on her, too. He admitted to having a crush on her since high school, and I think he wants to see what her pussy looks like when she's cumming.

I'm not queer, but I fantasize about watching another guy jerk off while he looks at my sister and sees her put things into her tight cunt. Just thinking about all the juice that comes out makes me hard all over again.
