I was used to doing most of the talking (as Rori’s fake online boyfriend, mister “Teacher”) in our conversations, but this new message of hers was downright rambling.
“Sorry it’s been so long… I can’t believe what just happened… I just came for my sister.
Okay, recap: My little sis caught me masturbating, as you asked. You told me to beg her for mercy, so I did. Well, she forgave me. Sort of. Not really… She’s holding it over my head, and we have this deal where she can take my stuff whenever she wants… More importantly, she… ordered me to do it in front of her.
I was shy at first (I’m still quite ashamed actually), but it was sooo hot. I think she was getting into it, she was staring straight at me. I could tell my face was bright red but just staring into her eyes got me… Really fired up. I couldn’t help but hope she was getting wet too. I felt so dominated and humiliated… I loved it. I sort of wished she would… push me further. I don’t know.
I hope you see this soon, I could really use your expertise, Teacher. And your cock.“
The message was dated from yesterday. While my pussy tingled distractingly, I noticed several things in Rori’s message. First, she was really starting to trust me, or rather “him” (oh sweet summer child). These were more explicit details than I’d ever had before. Second, she was starting to take a more active role. If she realized she could just ask Rori to fulfill her twisted needs, she might not need ol’ Teacher around anymore. Without my fake online persona, manipulating my sister would become much more complex.
And thirdly, she had me dripping through my fresh panties. I was mad with power, and it felt amazingly hot. I had to keep a firm grasp on her. I tentatively rubbed the wet spot on my soft underwear (I’d have to change them again. Bother). But I resisted doing anything, because I was in control here damnit.
Funny thing was, I didn’t even need to keep going. I had the video, I could stop at any time and keep blackmailing her forever. But I was simply not done humiliating Rori.
There were two other new, much shorter messages:
“I can’t focus today. Too wet. Can’t stop thinking about her gaze on my naked body.”
“I’m so confused, Teacher. I don’t know what to do next. And horny. I’ll probably start by using up all the AA batteries I can find.”
It was time to make the bitch heel.
“You will do no such thing. Good story though, you got me throbbing hard.” (I wasn’t sure guys really said “throbbing”, but she wouldn’t know either.).
“Since you have too much time to play with yourself,” I wrote “I have a new assignment for you. First off, hands off that pussy of yours today. No orgasm, no masturbation. Second, and most importantly, I want you to initiate contact with your sister. Get her to let you touch her pussy today. It shouldn’t be too hard, seeing as she loves to make you do things. Don’t pretend like you don’t want this.”
Even though I was alone, my face turned red at reading my message again. Of course, I had much more devious plans in mind. I sent the message, took a cold shower, and began the waiting game.
Several hours passed before I received her reply: “Anything for Teacher.” She must have been on her way home.
Soon after this, I heard her enter the house, and my heart immediately began racing again. I waited in my room, distracting myself on reddit until that fateful moment I knew would come. We were alone in the house, she had no reason not to go through with it. Hours passed, during which I knew she was mentally preparing herself, as was I.
When night was starting to set in, she knocked on my door. A shy knock, but less shy than the first time.
“Sis?” she ventured.
“Come in”, I replied with as much nonchalance as I could muster.
She came into my room smelling like perfume. The slut had actually hoped to secude me. What a joke. Although the red silk shirt and short black skirt she was wearing were admittedly very… refined.
“I found the vibrator,” she announced.
Oh shit. I had actually forgotten about the wet surprise I’d left on her pillow. I kept my composure.
“So what?”
“So I… I really liked it.”
I was actually stunned. I just stared at her, positively speechless.
“I can’t… do anything today,” she admitted, ”But I spent a long time… smelling the pillow.”
“What do I care, perv?” I said as the surprise made me drench my underwear for the third time today. I hoped she wouldn’t notice.
“I want… I would like to… touch you…” she whispered under her breath. She was beet red.
“I’m sorry, I don’t think I heard you. You want to do what exactly?”
“Ever since you made me…”
“Masturbate”, I chided.
“Masturbate in front of you, I’ve just been so curious. I just want to… feel it. I’ve been thinking about it a lot and I’m just so…”
She couldn’t finish the sentence, not that she needed to.
“You know you’re just digging your own grave here, right?” I queried. “You’re disgusting.”
She nodded shyly.
“Sit on my bed,” I ordered.
She seemed shocked and hopeful. Rori probably didn’t think this would work. Oh, it would work alright.
She sat at the end of my bed as I turned off the light, leaving only the faint glow of my old night light (I wasn’t about to be put in a vulnerable position).
I lied down more than I sat, opposite her. I slowly took off my white, soaked underwear, and spread my legs. The scent of my arousal filled the room, but that was just about expected now. She approached her right hand slowly, stroking my leg hesitantly, waiting for my approval. I couldn’t help but notice how soft her skin was. Little Miss Perfect as always.
“So you want to feel me?”, I whispered in her ear.
“Yes please!” she begged. So I decided to push it further.
I grabbed her by the hair and whispered harshly: “Then you can feel me with your tongue.”
Without further warning, I pulled her face down between my legs. I thought I would need to instruct her further, but Rori was surprisingly eager, and seemed to know what to do. She sucked on my clit expertly while I resisted the urge to smush her face into it. Then I figured, why resist, and I dirtied her pretty little face with my juices while her words echoed into my head: “I would love to taste another girl’s pussy.”
I exercised as much restraint as I could, my hand still firmly holding her pretty hair as I made her taste my clit again. She avidly ran her tongue up and down my slit without my asking as well. I wanted to pretend she was just so dirty and use her soft little mouth for all it has, but controlling and soiling her like this was just too much for both of us. She was moaning and breathing heavily, but I could hardly hear her, as I was positively screaming.
I needed to twist the knife before I completely lost control: “That’s right Rori, everything you own is mine, even your slutty mouth!”
As I resumed screaming without holding back, my voice echoed throughout the empty house; This was more pleasurable than anything I’d experienced before. And the one thought that got me over the edge was actually Rori herself. While she was licking me with more passion than I’d ever expected, I thought of my sister’s pussy, dripping like mine, for barely a few seconds before I lost it completely.
I wrapped my legs around her and started shaking so hard I could hear the bed rumble. My mind went blank and my screams turned into shocked gasps as Little Miss Perfect’s drank her own sister’s cum like fucking nectar.
After God knows how long, I fell onto the bed, exhausted.
Seconds passed. Before I could stop myself, I started stroking Rori’s hair. I tried to stop myself before she noticed, but I knew she did. So I forced myself to regain control of the situation, tired as I was:
“Go to your room and play with yourself,” I ordered sharply.
“But… I can’t today,” she replied, barely resisting. She was thinking of Teacher’s orders, no doubt.
“Who’s in charge here? Me, I’m in charge. So be a good little pet, get the fuck out of my room and come on your pillow some more.”
She looked conflicted for a second, then promptly got up to leave the room. Before I realized what was happening, she took off her underwear and put it in my open hand, presumably as a token of servitude and perversion.
As she left, I smiled and clutched the wet cloth proudly. Soon thereafter, I fell asleep in my own wet spot, still smiling.

So in short, the wonderful /u/sister_hannah, author of this series, seems to have given up on this story several months ago. I would link to them but it does not seem to be allowed on this sub.
Anyhow, as a big fan of hers, I decided to continue (and soon finish) her story. I guess you could call it fanfiction! Feedback is very welcome.
Thanks for reading!
Glad you picked it up! Keep at it :)
