I Wish I Didn't Know

I'm the middle child I just turned 19. I've with my mom and brother. My older sister live in the came city just a different house. We are a close family. I recently started a part time job. I've always been the shy type and it's hard for me to make friends. I met a couple guys who are a little older but cool. I was comfortable enough with them to try weed for first time and drink. I consider them friends. One is a major pervert. I can't say anything because I'm guilty of masturbating and still have a few of my dads old magazines. One day this guy tells me about something called camming. He explained it to me. I was instantly hooked. I found a few sites I liked and I slowly started finding cam models I liked.

There was a mix of everything from full on sex stuff to girls playing twister naked. Really big girls to skinny girls. Professional porn stars to everyday people. I found a search button and it let you search by location. I decided to look at my town. Nothing came up. I looked at the town close by that was a little bigger. A few names popped up. So there were ladies from my state camming. I decided to enter the big city an hour away. Tons of cams popped up. I started looking through them

I don't know if this has had to anyone but you see a person and the look familiar but it's not the person you know. Well I was looking at a cam and I saw a girl who looks like my older sister. I think to my self it can't be. I opened the cam and start watching. The girl on screen is bending over showing her ass in a thong. She says something about a certain amount of tokens and she would be in bra and panties. She was still with her back to the camera shaking her ass. She pulled up her shorts . Just then I heard a noise and she got excited she was thanking someone w she started getting undressed. When she did turn around. I still thought she looked a little bit like my sister but the heavy make up and color lights made it difficult.

It wasn't until she said a particular phrase that our grandpa used to say. I realized it was her. I felt my stomach fall. I felt nauseous. I sat there I didn't know what to think. I wanted to call her up say hey why would you do this. But at the same time here I am watching these other cam models and support them but I wouldn't let her do it. A while I sat there thinking her show continued I was so into my thoughts and not looking at the screen that I hadn't noticed she was already naked. When I looked at the laptop screen again I saw her sucking on a dildo. She was pretending to give it a blowjob. I want to turn it off. But I felt my chubby growing. I never noticed how big her tits were. She put the dildo between her tits and started titty banging it. The whole time people are tipping virtual I can see she had thousand plus people watching.

The more people start watching the more tips come in. The show goes from pretend blow jobs and titty jobs. Now she is flashing her pussy and licking her nipples. I'm hard now. It's almost painful keeping my dick in my pants. When she started finger herself, it was to late I had started masturbating. She went into a private show I was disappointed and didn't know what happened someone explained she was given private show but would return I asked how he did it. They told me how to buy tokens and stuff. So I bought some. When my sister returns the show continued.

I had to create an account so I was able to type now. I said hello and stuff. She was so enthusiastic. I was curious as to tipping I tipped finger for a minute. Sure enough she started finger herself for a minute. I was masturbating. I couldn't believe I was masturbating to my sister but here I was. I decided to take her private. She asked about me. I lied my best. It started off slow she was giving a blow job to a dildo. She would look into the camera and say my screen name . I told her deepthroat it. She said yes Daddy and did it. Hearing yes Daddy sent shiver down my spine. I started telling her to rub her pinch her nipples she did. When I told her to spank her ass she did. When I told her to start using the dildo on herself she asked which one. She had a massive collection. I told her to choose her favorite. She pulled out a 10 inch dildo. She started using it on herself. I watched. Stroking myself. I barely started stroking it when I prematurely ejaculated it was so hot.

She continued she stuck the dildo to a book and started riding it. Grinding back and forth. Her hips doing circles. Even tho I just came I was masturbating again. It was so hot. I knew it was wrong but at that moment I didn't care. She layed on her back. And started really pushing in the dildo. Eventually she pulled the dildo out her pussy was gapped open wide. A huge rush of her pussy juice started flowing. She ended up squirting. The private ended. I was happy to see it recorded a copy and sent it to me so now I can see it whenever I want. I've become a regular in her room. She still doesn't know its me
