Little Sis isn't Shy

This story is completely fictional!!!!!

Our parents spend most of there time out of town. So I'm home a lot with my sis. I'm eighteen. She's also eighteen, she's never had a boyfriend, and is still a virgin. Her name is Maree. She has the prettiest long strawberry blonde, with striking blue eyes, also she is a 32d natural boob, and she has the most pert round ass. Growing up I'd never thought of her as anything more than my sister but one day things changed. It was just after her seventeenth birthday. She came home from gymnastics practice and I was in the backyard cleaning the pool. I heard her yell through the house but I didn't answer. I saw her walk but the big bay window in her skin tight gymnastics leotard. She didn't notice me.

When I came in the house five minutes later, I heard the shower water running. I openned the bathroom door and saw her through the lace thin shower curtian. I watched as her hand ran down her front, over her natural, firm breats and down into her pussy lips. I watched as she fingered herself. Then I heard something that freaked me out but also slightly turned me on.

"Matt, Oh Matt." She cried.

I stood in the doorway listening to my little sis sayign my name as she fingered herself. I closed the bathroom door and went to my room. I took off my shirt and sat down on my bed. I was reading a comic book I found sitting on my bed. I then heard the shower water turn off. About five minutes after that, I heard the bathroom door open and then close. That was when Maree walked right past my bedroom door wearing nothing but her thong.

"Hey, Sis." I said laughing.

"Jeez, Matt you scared the crap out of me." She said smiling.

"Have a nice practice?" I asked causually.

"Yeah, hey wait, I thought you were going over to your girlfriends tonight." She asked curiously.(Also at the moment she is facing me, full frontal.)

"I walked in on her with her best friend's brother. She had his cock all the way in her mouth." I said and she looked at me shocked.

"That little slut." She said mockingly.

"You gonna put clothes on." I asked jokingly.

"Maybe." She said throwing her towel at me.

Maree walked out of sight and into her bedroom. I went to get a snack from the refridgrator. While I was making a sandwich, my sister walked out of her bedroom. She came right towards me and cut in front of me while I was putting the peanut butter on. That's when I felt her pert ass press against my large cock. I started to harden and when she noticed, she laughed a little. then walked over and sat on the couch. I grabbed my sandwich and joined her. When I looked at the TV I saw what shocked me. My little sis was watching porn. I looked over at her. She was in my t-shirt and was rubbign herself through the see-through lacy material of her thong. Her shaved pussy was just calling me.

"Sis, what are you doing?" I asked in shock.

"Pleasuring myself. You serious think guys are the only ones who need to release sexual tense." She glared at me. My cock was getting hard and it had nothing to do with the that there was porn on. I was getting completely turned on by my sister masterbating.

"Stop staring." She said throwing a pillow at me. I looked away for a mintue and then leaned over, kissing her softly on the lips.

If you think this is any good then I'll finish it. So let me know.
