Your Sister’s Onlyfans

Hello there! I usually make captions, and they often end up so long that I struggle to make them fit in one image, so I decided to try writing up a short story! This story features kinks such as femdom, CBT, incest, dub con, cucking, forced crossdressing, SPH, and a little bit of findom at the end, so if you dislike any of these, you’ve been warned. But if that sounds like something you’re into, I hope you enjoy it!

—————————

Your older sister had always loved to torment you. And being bigger, stronger, and far more assertive than you, it wasn’t hard for her to push you around. Even as young adults, sharing a dorm for college, she bullied you mercilessly for her own amusement. And of course, she loved to do so in front of an audience. Your classmates, her friends, anyone she could get to watch, she made sure they got the chance to watch and laugh as you got pushed into a trash can, dunked into a toilet, pantsed, or especially wedgied. It seemed childish, but the way your voice raised an octave when she grabbed the back of your underwear and yanked them in just the right way to make them squeeze your balls seemed to especially satisfy her sadistic streak. But one night, as she was lifting you up by your underwear, as you whined and squealed and begged her to put you down, all while one of her friends snickered and recorded your ordeal on her phone to send to your latest crush, you got your idea for how you’d get revenge.

You were very much still a virgin. And she was anything but. You spent countless nights lying awake, listening to her get railed by some big stud she’d picked up, or getting eaten out by some pretty girl. The worst nights were the ones when you brought home a girl you were hoping to finally get to sleep with, only for your sister to pants you in front of her, and ask “are you sure you want to let my ‘Little’ brother try to fuck you~?” With extra emphasis on ‘little’. You hated the way she went out of her way to cock block you. You hated the way she held up her pinky next to your cock. You hated the way it always gave you a tiny erection. And you hated the looks of shock, disappointment, disgust, and amusement on the face of your date. That look that told you that your date no longer considered you a man, and you just lost any chance you had of fucking her. Half the time, your date would end up in your sister’s bed instead of yours. But after getting wedgied on camera one too many times, you figured out how you would use this to your advantage. Your sister liked to humiliate you on camera and steal your dates? That was fine, but she was going to start paying you for the privilege with some on-camera humiliation of her own!

It wasn’t hard to find some small cameras you could hide around her room. And she went out to parties often enough, you had plenty of chances to sneak in to hide them. And of course, you had spent enough time and money fucking your fist to onlyfans girls to know how to set up an account (although “fucking your fist” might be a bit generous of a description. “Pinching your dicklet” is probably more accurate). The hardest part was sneaking into her room to grab her drivers license while she was sleeping to set up her account. You thought your heart would beet out of your chest, as you crept up to the table next to her bed to grab it, barely a foot away from where she was splayed out in bed in her underwear, loudly snoring. But still, you managed it, and then all you had to do was wait to get something on the cameras. You didn’t have to wait long.

Within the first week of setting up the cameras, you had recorded her giving a blow job to some frat boy and riding his dick, and riding the face of some nervous preppy girl who just wanted to “experiment”. On top of this, you got countless pictures and videos of her undressing and masturbating in her room. You soon found out your sister liked to get in work outs while naked in her room, and that videos of her doing naked exercise were quite popular. Her onlyfans grew, and grew fast, and you were making very good money off it. And of course, whenever she had a dry spell, all you had to do was bring some cute girl home with you, and your sister couldn’t resist cucking you. At first you tried to tell yourself you were just putting up with the humiliation for the money and the revenge, even though you always got a throbbing little erection when you edited and posted the videos. Then you tried to tell yourself you would only look at the other girl in the videos when you jerked off to them, you definitely didn’t get off to watching your own sister cuck you. But when it got to the point that you exclusively jerked off to the videos you took of her with ‘your’ girlfriends, the truth was obvious even if you refused to admit it. Still, the channel had taken off, and you considered your plan to have been a great success. As it turns out, you were too successful.

One night, your sister went out to a party as she often did, while you stayed home and masturbated as you often did, hoping she’d bring someone home to unwittingly fuck her on camera. But while she was at the party, she realized she was being watched. Specifically by some scrawny little dork standing alone in a corner, who was doing a very poor job of hiding that he was trying to look up her skirt. She stormed up to him to confront him and asked “Do you have a fucking problem, creep?”, and he stammered out “N-no! I’m just a huge fan of.. um… you know… y-you!”.
“The fuck is that supposed to mean?” she asked as she cornered him. “Your onlyfans! I love your onlyfans!” He replied, simultaneously the most scared and most aroused he had ever been. “I don’t have a fucking onlyfans you pervert!” She snapped. “What? S-sorry, I thought for sure it was you, you wear the same outfit, the same panties, and I think you even have that same birthmark on your inner thigh, right next to your pussy...”. As he said this, he rather stupidly squatted down to look up her skirt and find the birthmark. This won him a swift kick between the legs. The angle was awkward, so it was hardly as forceful a kick as it could have been, but it was still more than enough to make him double over and fall to his side, clutching his aching nuts and whimpering pathetically. Your sister crouched down next to him. “Alright creep, you’re going to show me this onlyfans you’re such a big fucking fan of, and unless you want to leave this party as a girl, you’re going to make a donation for me…”

Back at home, you were sitting naked in front of your computer, legs spread, your finger and your thumb frantically rubbing your tiny erection, your eyes glued to a video of your sister getting fucked into her bed by a man who was much, much better endowed than you. A notification popped up, someone had donated 100$ to send a message, that read “please make a video where you break the balls of a pathetic little virgin like me!”. The money was nice, but you paid no attention to the message, people made requests for their weird kinks all the time. You had headphones on so you could flood your head with the sounds of her moans. This meant you didn’t hear when your sister got back from the party early. You didn’t hear her walking towards your room. You didn’t even notice her quietly open your door, and walk up behind you. You had no idea something was terribly wrong, until you felt stabbing pain shoot up through your body, from her hand shooting down to grip your poor little nuts like a vice. You screamed in shock, pain, and terror, your mind raced to make sense of what was happening. You wanted to say it was a big mistake, that it wasn’t what it looked like. But she had caught you, pants down, fingers on your micro penis, with the video still playing in front of you. All you could do was beg for mercy. “Fuck fuck fuck, please let go!” You whined, and her grip only tightened. “You pathetic little degenerate…” she growled in your ear, her grip on what little manhood you had only tightening. “Which came first, hmm? Jerking off to your sister, or selling the creep shots to other pathetic little virgins like you?”. You tried to stammer out a response, an excuse, a plea for mercy, but each time you tried to form a sentence, the words got caught in your throat as she dug her fingers into your balls a little harder. Finally you managed to say “I-I’ll give you the money! All of it! Just fucking let go of me!”. “That’s right, every cent you made off of this, you’ll be giving back to me. And since you probably already spent most of it, you’re going to make back any money you spent, right?”. Your mind was fogged with pain, all you could do was say “Yes! Of course! Anything!”. All she said in return was “Good. Come on.”. And with that, she stood up and led you to her room by your balls.

When she finally released your poor, aching little nuts, you collapsed onto her bed while clutching them. Pain continued to radiate out of them in waves, a strange sort of pain you could feel in your stomach. But when you finally opened your eyes, you were so shocked by what you saw that you forgot all about your balls. Your sister was stripping naked in front of you. Every time you had seen the videos you’d taken of her, and every time you touched yourself to them, it made your skin crawl with a deep-seated feeling of wrongness. Seeing her body now, not through a screen but right in front of you, absolutely flooded your body with this feeling. But even so, your cock quickly hardened, having gone soft not long after your sister grabbed you. Your mind raced with what it could mean. Was this how you were going to earn her the money she wanted? Fucking your own sister on camera, for all her fans to see? It was a disgusting idea, but one you were more and more excited for the longer you looked at her. Even the look of disgust on her face when she turned around and saw how eagerly you were waiting turned you on more. But then she threw her panties at you and said “put them on”. All you could do was obey, as she dug out one of the hidden cameras and pointed it at you.

“Is this thing recording?” She asked, as you stood nearly naked in front of it, your erection making a tiny tent in the still-warm panties, your hands over your crotch to hide your shame. You nodded that it was recording, and she walked up next to you, shamelessly naked herself. “Hi there fans!” She stared off. She sounded so strangely cheerful. “This is going to be an extra special video for you all! I wanted to show just how grateful I was, to everyone who’s supported my onlyfans so far! First of all, to my pathetic ‘little’ brother. And I do mean ‘little’!”. She then looked over to you and whispered “Put your fucking arms down…”. You obeyed, and when you did, she hooked a finger into the panties you were wearing, and pulled them down to expose you. “Awww, isn’t that little virgin shrimp dick just adorable~. And it was my virgin little brother who gave me the idea of how best to give thanks to you, my fans! You’ve all gotten to watch how I treat beautiful girls, and big, strong, well-hung studs, but they aren’t the ones who support my channel! No, I’m guessing all of you are a lot more like my pathetic, shrimp dicked, perverted perma-virgin little brother! And you all deserve to see exactly how I treat guys like that!”. Then she turned to face you. “Alright little bro, spread your legs for me~” she said. Your face went white and you frantically shook your head “no”. Her smile cracked, and you could see the fury in her eyes. “Now, you little shit…” she said, her voice full of barely concealed rage. You were far more terrified in that moment of what she’d do to you if you misbehaved than what she was going to do if you obeyed, so slowly, shakily, your widened your stance. In the blink of an eye, her knee shot up and was buried in your crotch. Your balls flattened, like hard boiled eggs getting squeezed under a fork. There was a split second where you felt nothing, then the flood of pain washed over you, and your legs gave out. She caught you and held you against herself to keep you upright, and you whimpered and tried not to cry. Slowly, your strength came back, though the pain didn’t subside, and you were able to stand on your own again. She let go of you, took two steps back, and swung her leg to kick your balls into your throat. The pain was so much that you couldn’t even scream, just whine and cough as you fell back onto her bed. You crossed your legs and clutched your crotch as you rolled from side to side on her bed, though your nuts were so swollen and sensitive that even holding them yourself was painful. “Awww, what are you whining about you little bitch? Aren’t you happy? It’s the first time a girl has touched you!” your sister mocked and laughed. Then she turned back to the camera. “Now, if any of you pervs try and walk up to me again, you know exactly what will happen to you! But in case you need a reminder, my poor little brother will be repeating this performance every day this week! Oh, and the top donor at the end of the week gets to decide what I do to him next!”
