Sister spying on me while I rub my cock

100% Fiction

My sister and I had moved back into our parents house at age 23 we were both college drop outs but we worked to make up for it.Today was my day off and I had gotten extremely horny around mid day right around the time my sister goes to work. God what a body she has Long red flowing hair,glasses perfect lips,gorgeous face and smile, hips and curves,large plump supple ass and double d cup breasts.I knew she stashed pictures of her naked on her computer profile. I had walked in on her "by accident" many times while she was taking them. She would be in her towel unwrapping it and taking quick snap shots of her body.

When she saw me she would scream at me to get out.But I wanted those pics so badly.I looked at the computer in my room. I started guessing her password. getting closer and closer to seeing her pictures. I finally got it looking around as it started signing onto my sisters profile.As i loaded it she had a blown up picture of her topless with her bare legs folded over to cover her pussy. I gasped not taking my eyes off the screen wanting more. My cock started getting harder. I have a pretty big cock all natural 18'' cock. It started hurting getting restrained by my pants and boxers so I unbuttoned my pants and gave it some air.

As i opened the folders they were all lined with pictures of her naked. Pussy shots,her fingering herself,massaging her breasts,taking it in her ass with a dildo,plain spreading her pussy,and taking it from a dildo in her pussy. I was awed at it. I took out a usb flash drive and shoved it in the computer downloading and saving all of her pics for my enjoyment later. I couldnt help myself I gripped my hand around my cock and started rubbing it moving my hand over the shaft up and down the tip. I wanted to be inside her so bad. I continued to rub it spouting off talk like i was actually fucking her.

"Thats right Isabella take it I knew you wanted your brothers hard cock for so long! Feels good doesnt it baby!" I said still rubbing it to fucking her.

Isabella walked down the hall way in her uniform for work and opened the door hearing the commotion.She had barely opened it when she noticed what I was doing and quickly put it to merely cracked doorway.She peaked threw again staring at my rock hard cock as it stood way taller then the comp screen.I continued not seeing or hearing her but she was watching my every motion. Her eyes widened as she put her hand over her mouth. "Holy shit he is huge!Oh my god brother my god how you've grown!" She watched me rotate and grip my hand up and down my cock with an intense stare.

I rubbed the tip and started moaning her name "Oh my god Isabella!Ride my cock!"

Her face blushed bright red."Is he rubbing his cock to the thought of fucking me?" she thought to herself. She opened the door a bit more and saw me on her profile with 12 views of her pictures up.She couldnt believe she was getting so turned on by her own brother but she loved staring while i played with it.She worked her blouse open and pushed her palm against her breast rubbing it gripping it tightly as she moved her hand up and down on it.She lifted her skirt up pushing her hands inside her panties lightly fingering herself and rubbing her clit to the sight of me rubbing my cock tip.

She put her shirt collar in her mouth to muffle her moans her cheeks now blushing beyond belief."I cant take it I want it so badly!" She swung open the door and my jaw dropped as she stared at my hard cock trying to act shocked.... To be continued in part 2
