Down the Hall

My name is Dan, I am 18 and I am sharing a room with my sister Ellie who is also 18. We were sharing a room a couple of rooms down from our parents. I made a fake snapchat account and pretended to be a guy called Zack. I knew my step sister was single at the time and was getting back out there. So at 10:30pm I started a general chat, asking where she was from and what she liked. Eventually, the chat went sexual after messaging until 11:00pm.

After a few messages about how hot she was, I sent a picture of the top of my boxers (previously saved pictures as I was sitting meters from her). she replied with saved pictures as well of her bra and thong. I was getting so hard I had to go into the bathroom to reply to her. Once on the toilet, I sent a picture of my dick and she replied with damn that would be the bigger than my exs. I came instantly, straight into the toilet. She then messaged that she would send some pics later in the shower as she was sharing a room with her brother. Once I sat back down, I started to ask her about her brother. She said that he was a year older. I walked back from the bathroom to bed and I asked the dangerous question "Do you have any fantasies?" She opened the message but didn't reply. I thought I'd blown my cover. Eventually, she did reply at 11:26pm. she said, "One time I had a dream that he kicked my ex off me and fucked me himself." This felt like an opportunity.

She got up from her bed and went for a shower and sent a lovely nude picture, waist up, in the mirror. I then asked if her brother had seen her naked. she said "I think he's seen my boobs once, when I came out of the bathroom." Which was true, she had beautiful small tits and now I have a saved picture of them. I tried to get her to flash over snapchat again, but then I heard the bathroom door open. She walked back to her bed and I said I was going to shower now.

While in the shower, I sent her some dick pics, which she liked, and she replied with videos of her fingering herself with her pajamas pulled down. However, in one of the pics I sent, there is a body wash bottle, which she ended up recognising.

She knocked lightly on the door. In my excitement I forgot to lock the door and she walked in. I stood in the middle of the shower with a fully erect penis. She opens the glass door and says "are you Zach?" She had an angry look on her face, so I answered yes. She flashed my her tits and said "Well, Zach. Is this what you wanted?" I was speechless. "Take a picture ZACH, it will last longer," I raised my phone and took several pictures of her. "Hump" she grunted as she put her shirt back and walked out of the bathroom

I followed shortly after and saw she was in bed, I got into my own bed. At 12:14am, she messaged me on the Zack account and said, "Can I sleep in your bed tonight?" Of course, I said yes. It was dark and I didnt see her coming. But she climbed into my bed and pushed her ass into my erect dick. I slowly slid my hand down her soft arm, when I got to her thigh I noticed she was naked. I pulled out my dick and put it between her thighs.

She adjusted herself around but couldn't get it in, So she reached around and grabbed my dick and put it inside her. "Maybe this is what you wanted, Zach?" she said slowly grinding on my penis. I just let her do it, stunned. She didn't seem amused I wasn't helping much. She rolled me onto my back and got on top of me. She slowly slid down on my penis and sat there. I was still too shocked to do anything. She got out her phone and took a selfie. My phone went off and I checked it "is this what you wanted ZACH?" She sent me through the fake snapchat account. It was the picture of her on my dick. My phone dinged again. "Take a video it will last longer ZACH!" This time it was a picture of me looking at my phone.

I switch the the camera app and start recording, The light is set on so I can see her. She starts riding me, my dick is throbbing. She keeps switching positions, on her knees, leaning forward, leaning back, bouncing and grinding. My favorite was when she was up squating on my dick. It was so hot I stopped the recording and snap chat her saying "I'm gonna cum." She sat squated on my dick and wrote to me "Where does ZACH want to cum?"

"On your face," I replied quickly. She read the message and rode me a bit longer, she could feel me clawing at her to stop cause I was close. She got off me and snap chat me again. "You get one shot at this zach, you better record it," she stood up and pulled me off the bed. She got on her knees and started sucking. I turned the camera light on and started recording.

I was still stunned so she was doing all the work. I have no idea where she learned to do this but after 20 seconds of massaging my balls I pulled out of her mouth and said "I'm gonna cum." She kept fondling my balls and stroking my dick pointed at her face. I came all over her face, her eyes, her forehead, her mouth, her nose. A knock at the door.

We both jumped into our beds, I turned off the light on my phone and then dad walked in and turns on the light. "Hey, why are you two up so late?" dad said very sleepily. He walked between our beds and looked at Ellie "What are you doing missie?" Knowing I just came all over her face she had no time to clean it.

"Just a late night face mask dad," she said as she rubbed my cum into her skin all over her face. I was still recording all this secretly.

"All right sweet heart, don't stay up too late. Good night to you too Dan. I know you're a bit old to be sharing a room but we will sort it out soon." He left the room, turned off the light and closed the door. I turn my phone light on, still recording and I see ellie standing up naked, most of the cum now rubbed into her skin, but it was a lot so you could still tell it was there. She picked up her PJ's and went back to the bathroom to clean up. I stop recording and make a small clip of the video. The part where she was rubbing the cum into her face. I sent her the video in a text and said "This is what Zach wanted."

She came back into the dark room locked the bedroom door and crawled back into my bed. "I prefer the name Dan anyways," she said as she backed up into me I could feel she was still naked. I reached down to touch her pussy and she grabbed my hand and brought it to her boobs. "No more tonight, maybe tomorrow." and with that we both went to sleep.
