[MF] Made my sister cum on Webcam.

I found out that my 18 year old sister is a cam girl. My sister Dawn is dating my best friends younger brother, he mentioned it to my friend Bret. Bret then told me his brother feels uncomfortable with the kind of attention she was getting and he was feeling inadequate. I feelt my cheeks heat up as I listened. Dawn and I used to be close but since I left for college we have become a little distant. I’m only an hours drive from our parents house but I will admit, I haven’t been back home but maybe 2 times this semester. I called Mom and made plans to come up this weekend to spend time with the family.

It was a long week of testing but Friday finally rolls around and I pack up and prepare for the drive to my parents house. Bret walks with me to the car. “Are you going to talk to Dawn”? I slide into the front seat “For the sake of your brother or because you think I care what she does, she’s an adult?” I roll the windows down and shut the door, he leans in. “Just talk to her for him, it’s pathetic watching him mope around”. I shake my head and roll the window up and pull away. Bret knocks on it as I start to back up with a smile “have fun”. The drive was long, and traffic was horrible but by the time I reached home, I was starving. I just walked right in and my Mom was putting her shoes on in the entry way, she embraced me as I came in. “Dawn and I are getting ready to head to the store we are making your favorite for dinner”. I hugged her again and told her I was happy to be home. I headed upstairs to my old room to put my stuff down, everything was the same, minus the mess, mother must have cleaned it. I just thew everything on the bed in a hurry to catch Dawn before she left.

Her door was cracked, I couldn’t help but peak in before I knocked. Her black hair was down around her shoulders and her back was to me. She was at her desk. I knocked and pushed the door open. Dawn spun around and jumped into my arms. “Bry I’ve missed you”, I hugged her back tightly as I pulled her in I could tell she wasn’t wearing a bra, her nipples brushed against me as she pulled away. Why did I notice this? I look closer are her, her chest filled her top, her ass stretched her leggings. When did she look so grown. “Bry is something wrong?” She always called me Bry, short for Bryant. “No I’ve just been away awhile, you’ve grown” she giggled “it’s only been a year”. We conversate a bit then she leaves. I watch as they pull out of the driveway from her bedroom window. I do a slow 180 in her room. For the most part it’s the same too. Besides the new computer she had received for Christmas. I sit at her desk and opened it. I wasn’t sure what I was expecting to find but this was not it.

She was on a site I didn’t recognize and in the top corner was a profile icon with the name “Dawnunder-you” I felt my cheeks get red as I scrolled. Photo after photo flashed by until one captioning “cum play with me” she was holding a pink remote control vibe and her top was off, there was also a time and passcode. I kept scrolling. A photo of her ass flashed across the screen and she was spreading her cheeks. My cock twitched and I slammed her computer closed. I went down stairs with my head spinning. Was my sister turning me on ?

Dinner was great, and so was the movie. Before I knew it my parents were off to bed leaving me and Dawn downstairs. The conversations between us were light, casual, friendly and comforting. I couldn’t bring up what I saw on her computer, so I didn’t. Tomorrow maybe.  She eventually hugged me goodnight and went upstairs. I looked at the clock and noticed the time. My stomach jumped and her photo flashed in my head “cum play with me 11:30”. I don’t know what drove me to do so, but I went upstairs and closed my door. I packed my computer so I pulled it out and logged in. I typed in the site and a search bar popped up, I typed in her name and It asked for a password. My hands are shaking as I typed it in. It loaded and her room popped up on my screen. My stomach turned. She came into view and my cock throbbed. She was topless and in a black thong.

I quickly put my headphones in and turned the volume up. She sat at her desk and spread her legs open. Her pink vibe sat on the desk next to her among other toys. “So who is going to connect to my toy and make me cum” she started to rub her pussy as she was bombarded with messages. “Whoever can guess my favorite color first gets to control me” and before I could help myself I typed “pink” because despite her edgy look, pink was her favorite color. My display name popped up “Bonedaddy”. She leaned in to read “wow first try, alright daddy here’s the code”. She private messages me the code. I  downloaded the app on my phone and connected. She stood up and pulled her panties down nice and slow turning her ass to show the camera, she was visibly wet . She spread her legs wide and inserted the toy. The messages went crazy and so did my heart, it was pounding. I knew i should be here but i couldn’t look away. Her pussy was beautiful it was pink and swollen with arousal. Her lips folded nicely around the toy. What was I doing? A little line with a circle floated on my phone screen and I hovered over it for a ling time “what are you waiting for baby, im ready?” I dragged the circle up and she twitched. “There you go”. I slammed it all the way to the top and she let out a moan. My cock throbbed again. I reached down and stroked it a few times. I was so hard the pre-cum was everywhere. I couldnt help myself. I took my shorts off and moved the circle again.

She grabbed the arms on the chair and closed her eyes. I started moving it up and down. Causing the vibrations to go slow and fast. Her cheeks flushed and she gasped when I brought it to full speed. “Yes right there, I will cum”. But I dropped it down to low. Her legs fell shut some as she opened her eyes. “Naughty boy”. I started stroking to the motions and patterns I created. I brought the toy to max power again and locked it. She twitched and let out a moan loud enough for me to hear down the hall. The messages flashed across the screen like crazy. One username caught my eye. “Bigmankev” it was her boyfriend, he was in the chat. He used the same name as his gamertag. He was watching me play with my sister, his girlfriend. He commented “does it feel good?” She moaned again and said “yes baby, so good”. I  started to move it up and down, causing it to pulse. Her chair was soaked and she was rubbing her pussy. I leaned over and typed “beg” her face went red. I could tell she’s never had that response before and everyone else in the chat confirmed it. “P-Please let me cum” I shot the control up and locked it again. With a moan she leaned back and grabbed her tits, her hips thrusting against the vibrations. Her toes started to curl some, so I lowered the vibrations again. My cock was dripping, I started to squeeze it a little tighter as I watched her panting. Moving my hand up and down it twitched, I was close. “Beg” I typed again. “Please daddy, please let me cum” I set the toy at full power again, she clutched the chair, her knuckles going white. The chat went wild. “Please, please, please” I moved it up and down. Slow, fast ,slow fast matching my strokes with it. “I’m cuming she yelled” and I thrusted one last time into my hands and rope after rope of cum fell onto my belly. She stopped rubbing her clit and yanked the toy out showing the chat her pussy contracting as her orgasm overwhelmed her. I closed my computer fast ending the connection. I sat on my bed confused, almost disgusted but still hard. I don’t understand what’s happening. I cleaned myself up and layed down. I stroked myself a bit more before opening my computer up again. She was still online. And she had posted a new photo. It was a picture of her cum covered toy captioned, “best orgasm ive ever had” I sent a privet message “that was fun” and she responded fast “again sometime?”
