After talking to Rori the first time on Reddit, I decided I wanted to see how deep her perversion went. Here was my sister, that I always thought of as this squeeky-clean good girl, and now I was seeing this whole other side of her; this dirty, slutty, humiliation-craving side. I wanted to see how deep this cave went. And Rori made it easy. The next night, shortly after Rori went into her room, I got a new PM on my new account. She said she had really enjoyed the previous night and was looking forward to repeating the experience.
She asked about me and I told her that I was a guy in my mid 30s, a teacher in real life (that really got her interest), and that I lived in a city far away from where Rori and I live. I figured that if I said that I lived nearby she may ask to meet one day, and then what the hell would I do? I also asked her stuff about herself. She told me about her studies and stuff like that. Nothing I didn’t already know.
She said she wanted to continue the teacher-student roleplay, so we went back into that. This time, we worked more into the control and humiliation aspect. Picking up from where we left off, we pretended that she was the same student in my class. Only now, I was turning her into my little sex slave over the course of a number of classes. I would make her come to school without panties. Give her “extra credit” for spreading her legs in class, knowing full well that the other students might see. And then, even making her masturbate in the middle of class.
She was really enjoying it, and much like the night before, I was too. This time, I didn’t feel too weird about masturbating to this roleplay. I made sure to not make too much noise so that she wouldn’t hear me in her room. In the roleplay, we got to a point where we were having sex after class again. I was fucking her bareback over my desk, and then making her lick all her pussy juice off of me. She said it tastes delicious. I asked her if she was going to follow all my directions for her, even if they were humiliating. She said she would.
“In real life, too?” I asked her.
Her reply was delayed. “I don’t know. I’ve never done anything like that before :/”
Damn. It was a little disappointing to know that Rori’s secret life didn’t include her walking around in public in nipple clamps or doing anything too humiliating yet. But mayve I could change that. “We can start off slow, and see how you like it. Then if you don’t, we can stop. But I love the idea of knowing you’re really out there following my directions, humiliating yourself in situations where you could get caught and exposed for being a dirty slut. My dirty little play thing.”
She wrote back. “Mmmm, that sounds so hot.”
“Just imagine. You walking around, doing these dirty things with others around. Just our dirty little secret that nobody around you knows. Nobody realize how wet your getting around them. People right next to you now knowing what a dirty little slut you are.”
“Mmmm… I’m so wet right now.”
“Are you playing with yourself?” I didn’t need to ask the question. Rori was being louder than she was night before. She was really eating this humiliation stuff up. I could hear the wet slapping noise of her hand against her pussy going much faster than the night before.
“Yes,” she wrote back.
“Did you get your dirty juices all over your underwear again?”
“Yes, teacher. I’ve been a dirty girl.”
“Show me how wet you’ve gotten them.”
There was a couple minutes delay before her next message, but it contained an imgur link to a grainy, dark picture from her laptop webcam. It looked like she was sitting on her bed, with her laptop sitting in front of her. I could see her blanket and on top, there were her legs, spread to show a dark wet spot in her baby blue, bikini-cut panties. Wow, I thought, she wasn’t exaggerating.
“You have been a dirty girl,” I wrote back. “Look what a mess you’ve made with your horny pussy.”
“Mmmm, what do you want me to do teacher?”
“Take them off. I want you to lick every bit of your sluttiness out of those panties.”
“YEs, teacher.”
“Do you like the taste of pussy?”
“Yessss. I’ve never tasted any pussy but my own. But I want to.”
Wow. My face turned red. I was learning new things about Rori left and right. “Show me a picture of you licking out those panties.”
She sent back another grainy webcam image. I could tell she was trying as hard as she could to not include much of her face in it. I couldn’t see her eyes, but I could still see her cheek, some of her hair, her lips, and of course her tongue as it dipped down into the wet spot on the inside of the underwear she was holding spread out under her face. She was wearing a t-shirt as well.
“Good, keep sucking on that juice. Rub it all over your lips so you’ll be able to taste it for and smell it.”
“Yes, teacher. I’m so horny, teacher, please let me cum.”
I smiled. She wanted me to let her cum? I like the idea of having control over when she could orgasm or not. “Not yet. First you need to be punished for being such a dirty slut.”
“Yes, teacher. How do you want to punish me?”
“Take of that shirt. I want you you to pinch your nipples and turn them for me,”
“Yes, teacher. It hurts, but I need to be punished.”
“Now, I want you to spank your ass. And say out loud that you are a dirty slut.”
“But teacher, my sister is in the next room. She might hear me.” I didn’t know she realized I was here. I’m surprised she made as much noise as she did being fully aware that I was there.
“Good,” I wrote back. “Maybe she will hear you and learn what a dirty, perverted little slut her sister is.” Oh, if she only knew, I thought to myself.
I quietly crept over to the wall like I did the night before. I didn’t hear anything at first, but then a quiet clicking of her mouse, ostensibly as she read the PM from me. There was a few moments of hesitation, followed by a loud slapping sound, and a quiet voice (not quite a whisper, but still quiet) saying “I’m a dirty slut…” and then once more a bit louder “I’m a dirty slut.” After that, her typing.
I crept back to my computer to find “I did it, teacher. I don’t know if she heard, but I’m so horny. Please let me cum.”
“Very well, I want you to play with yourself now. Make yourself cum as hard as you can.”
“Yes, teacher.” She wrote back. I didn’t even need to go put my ear against the wall to hear her this time. She seemed to be getting a lot braver about making noise. But I crawled over to the wall anyways, after sending her a message telling her to message me when she finished. Listening to her play with herself was odd. If I didn’t think about the fact that it was my sister, it was really hot. Like listening to a really good porno; a girl who was getting off and enjoying it immensely. Plus, I’ve always had a bit of a thing for voyeurism. My body’s natural reaction was to just enjoy it and get more turned on by it. I carefully unbuttoned my jeans and slipped my hand into the waistband. I was so wet, I couldn’t believe it. I would have guessed that if I had stripped off my pants then and take a picture with my legs spread, the wet spot would have rivalled the one Rori sent me a picture of.
My mind tottered back and forth about playing with myself, but I still thought it was a bit too weird. Plus, I didn’t want to make too much noise and alert Rori. And judging by how hot I was, I wouldn’t have been able to stop myself from making alot of noise if I played with myself. So instead, I sat there with my ear against the wall, and my legs slowly rubbing together as I listened to my sister rub her fingers into her soaking wet pussy faster and faster, moaning more and more. Eventually, the wet noises got louder, like she was actually slapping her pussy, then a muffled cry, followed by tired breathing.
Back at the computer, I had a message saying she had finished. “Amazing,” she replied. “I had to stick my face into my pillow to keep from screaming.”
“With all that pussy juice over your face, that means your pillow is going to smell like pussy when you sleep on it tonight.”
“It wont be the first time I’ve gone to sleep on a pillow with my pussy juice ;) I rub against it sometimes when I’m horny.” This was news to me. I mean, not just the fact that Rori did this, but the fact that this was a thing. I had never heard of this whole pussy-pillow thing before. Would that even work? I didn’t think about it too long. I was going to write her back, but first I saw I got another message from her. “I’m so dirty from sweat and my juices. I need to go take a shower.” An idea popped into my head. Time to test the limits.
“Before you go take a shower what are you wearing?”
“Just a bra and socks,” she wrote back.
I didn’t realize about the bra, but I had a quick idea to give her a little humiliation. I asked her where the bathroom was. I already knew the answer; it was just down the hallway across from my bedroom. Going from her door to to the bathroom was maybe a 7-foot walk, and there were no windows in the hallway. She wrote back saying it was down the hall.
Before I wrote back again, I carefully crept over to the office door and opened it a crack. Just enough that I could see into the hallway. Then, I wrote back to her “walk to the shower without putting any more clothes on. That is your first assignment.”
“But teacher! Someone could see me, my family is here.”
“Are any of them in the hallway?” I asked. She said she didn’t think so. “Then go. Let your wet pussy breath a little before your shower.” I followed it up with “That’s an order.”
“Okay, teacher… I’ll try.”
As fast as I could without making any noise, I made my way back over to the door. It opened in the direction of Rori’s room, so from the dark office, through the crack in the door, I could see Rori gently open her own door and peek her head out. She looked in my direction. For a moment, I thought she saw me looking, even though the office was dark. But then I figured she was just noticing the door was cracked. After looking down the hallway for several seconds, then turning her head towards the bathroom, then back down the hallway, I saw her spring out of her door and into the bathroom, shutting it close behind her. It was dark, and I couldn’t see much, but I could see she was wearing nothing but a bra and socks.
I heard the water start running in the bathroom, and decided to creep into her room. Rori always took long showers, so I knew I had a bit of time to snoop around. It’s not like I hadn’t seen the inside of her room before, but something felt very different about seeing it this time. There was her bed. But it wasn’t just her bed; it was her bed that she just masturbated on. There was her laptop. But it wasn’t just her laptop; it was the laptop that she took a picture of herself licking her pussy juice out of her panties with. And there was her pillow. The one she shoved her pussy juice-covered mouth into to muffle an intense orgasm.
I looked closer at her pillow. There was a little bit of dampness on it. There was a little bit of moisture there, but not enough. And maybe some of it was just saliva too. I kind of had this vision of Rori sleeping in a shameful puddle of pussy juice, and this was disappointing. I gave the pillow a little sniff, and then I realized something was wrong. This isn’t what I wanted. I didn’t want to be sneaking around smelling her pussy. That was more degrading to me than her. If anything, she should be smelling mine.
That’s when I got the idea. I remembered what Rori said, about how she would rub against her pillow to get herself off, and thought about how wet I was. I turned my head in the direction of the bathroom. I could still hear the water running, and even after it turned off I figured I had a couple of minutes while she toweled off before she came back to her room. Knowing I had some time, I quickly unbuttoned my jeans and slid them to the floor, then took my panties off and set them down and crawled onto Rori’s bed, straddling her pillow.
I was still super wet from before, so I was happy to see a wet spot start to appear right where she would be sleeping. “That’s right, Rori, sleep in my cum” I thought. I pictured her face laying in the wet spot, smelling all that girl juice while she was trying to sleep. Maybe even sucking on the pillow case like she did her panties. Or even playing with herself, while she breathed in what she didn’t realize was her own little sister’s cum. “Eat my cum Rori. Eat my cum, Rori.” the sentence kept playing over and over in my head as I rubbed my pussy against her pillow. And it felt so good. I didn’t plan on getting off when I decided to rub against her pillow, but it was hard not to. I guess she knew something I didn’t with the whol pillow-humping thing.
I kept going and going, careful not to make too much noise but I did let out a moan or two when I was was reaching climax. Afterwards, I looked at the pillow to see a nice wet streak I had left on the pillowcase. “Suck on that, Rori,” I thought with a smile and got my underwear and pants back on. Just as I was zipping up, I heard the shower stop, so I quickly exited the room and closed her door behind me. She opened the bathroom door, in a towel, and carrying her clothes, just after I got out. I made like I was in the hallway because I was waiting to use the bathroom.
“Hey, Rori.” I said as I slide past her in the hallway. I was worried that she might have some idea of what I had done, or that I might be a little flush because I had just cum, but she didn’t seem to notice. If anything, she seemed more embarrassed to see me, and quickly looked down after acknowledging me.
After I got out of the bathroom, I went back to the office and checked my reddit account. There was a message from Rori, saying that she managed to go to the shower without putting on any clothes, and saying how hot she felt thinking that someone might catch her. She said she felt so hot that she even played with herself again in the shower. “Jeez, no wonder she always takes so long in there,” I thought.
I wrote back saying that I came too (which was not totally a lie this time). Which, since she thought I was a guy, she took as a sign that I was ready to end it and go to bed.
“Goodnight, teacher. I hope we can do this again soon,” she wrote me. “I got so turned on walking through the hallway bottomless. When my sister was just down the hall. I’ve never felt so fucking hot before. I almost want to masturbate for a third time, but my room already smells so much like pussy.” I had to chuckle at that last comment. She was completely oblivious apparently.
“Did it feel hot knowing she could have caught you?”
“Oh my god, yes. Actually, on my way back to my room, I saw her in the hallway. I immediately thought about what if I had run into her on the way to the bathroom, instead of the way out, and the thought got me so turned on. Imagining being caught by her with my pussy out.” This was insane. Now she was actually fantasizing about getting caught by me.
“What would you do if she caught you?”
“I don’t know. I would lose my mind. It’s so terrifying but so exciting. I don’t want her to find out what a dirty slut I am. But at the same time, the thought of her finding out makes me so hot.”
“Follow my homework,” I wrote back, “and we can walk that tight-rope.”
“Yes, teacher. What homework do you have for me?”
This was all such new information. I hadn’t even thought about Rori having these kinds of desires. I knew I could use them against her, but I had to be smart about this. I needed to plan. “For now, your homework is to get some rest. I’ll give you a new assignment in the morning.”
“Yes, teacher. I can’t wait for you to humiliate me *kiss*,” she wrote back. She went to sleep. But I stayed up for a few more hours planning how I was going to use this.
