A look into the future:

Your girlfriend was disgusted with you. She will never look at you the same way ever again. You told her all the basic bullshit about taking it as a compliment etc.

But for some reason she didn’t give up on you. You worked on it together and you made some progress. You started to last a view thrusts, then eventually even 2 or 3 minutes. You promised your girlfriend that it will get more. But it was almost impossible to push these thoughts out of your hand that your sister implented in you. Every time they come up you get an uncontrollable orgasm during sex.

At the same time, your little sister becomes friends with your girlfriend, and subsequently gets to know friends from your social circle. You notice that she keeps on giving your girlfriend subtle ideas about having sex with that fuckboy from our group, that is interested in her.

You confront your sister angrily. She doesnt defend herself, simply says: “Would you forgive me if I show you my boobs again?”

You are speechless. Of course you desperately want to see them again.. But of course its not dont like this…she destroyed your life! You tried to make that clear, she just pointed at the bulge in your pants.

Then she kissed you. No tongue, not yet. You lost all your resolve. She whispers: “Come on, I know you liked it deep down. You liked to become a premature ejaculator for your little sister. You like to be humiliated by me. You liked when I had control over your dick.”

You: “Thats not true! I hated it!”

Sister: “Your dick doesnt lie. Tell me, do you want me to turn you into a premature ejaculator for life? Mess with you with my naughty little games, until you are completely unable to penetrate a woman ever again? Until your girlfriend will inevitably cheat on you with your friend? I know it doesnt take much anymore…”

You start to breath heavy, your dick is twitching…She looks at your dick. It is rock hard. She drops your pants and says: “Do you want to become a premature, pussy free virgin for me, for the rest of your life? Do you want to give it all up for your little naughty sister?”

You close your eyes, you moan…thats not possible..are you really…?

Sister: “Do you want me to permanently end your sex life?”

In that moment, you start to cum. You jizz unwillingly all over your sisters legs, feet and carpet. You fall to your knees, while you see her getting something from her desk. Its your chastity cage.

Sister: “Come on Bro, we have a lot of work to do.”

She really did it this time. Every time you slept with your girlfriend, you came earlier. Of course at some point, at a home party. You couldnt find your girlfriend. Your little sister came, took your hand, and lead you up to the bedrooms, where she signalized you to slowly and silently open the door a little. There you saw your girlfriend, lying half-naked already, making out with a guy from your circle. You didnt say anything. You just stood there watching, while your sister touched herself next to you. You didnt even blink.

The guy undressed her completely and kissed her so deeply while her hands ran over his body and grabbed his ass. The guy said that he wants to fuck her so bad. She responded that they shouldnt, she has a boyfriend after all. -nice, thats your girl! you thought- Then the guy said that he will fuck her better than her boyfriend ever did, while touching her pussy. She started to moan and move her hips like she is going crazy, and she says: “Yes..yes..I know you would”

The guy: “He doesnt fuck you properly huh?”

Your GF: “N-no..never…he always….cums…too fast…”

The guy: “hahaha, how fast?”

Your GF: “seconds..”

The guy, now pressing his cock against her entrance: “Then beg me, to fuck you hard now!”

Your GF screams, so loud that you are worried other in the party will hear it: ”Please, please fuck me! Fuck me for real! Fuck me like a real man!”

That moment he enters her, she moans, much louder than you ever heard. And he fucks her…for 45 minutes. Hard. She cums, several times. They talk dirty half of the time, about what a loser you are, about how she will keep on cheating on you until she finally leaves you, how she will never get enough of this guys dick…and so on..”

You lost her. And while you are just standing there watching, your sister notices the growing wet patch on your pants. You just came in your pants, from watching your gf get fucked. Your sister laughs at you so loud, that you are sure your gf noticed you. But she didnt. She gets fucked into another dimension at the moment.

It was a few more months of her cheating until your GF finally broke up with you. She told her friends about your premature ejaculation problem, who told their friends, and then every single person knew it. You degraded to an absolute servant of your little sister. You completely gave up on sex, as she got you to a point where it was impossible for you to penetrate a woman.

She locked you in chastity, and whenever you wanted release, she challenged you again. Your goal was always the same, trying to to cum. And the punishment was always the same as well: longer time in chastity. The more time youre in it, the more does your dick shrink. She introduces progressively smaller cages to facilitate this process.

First it was days, then weeks, then eventually months. Finally it was about a whole year in chastity. You lost.

The year is now over and you are about to be released. Freedom. When she unlocks the cage, your dick doesnt fall out anymore. Its tiny, shrunken down to lass than 3 inches. Your sister makes you one final challenge. The last challenge of your life. She will undress herself, kiss you, touch you, and rub her body against you. She will even push your tiny dick inside her pussy for the first time. All that for 5 minutes. All you have to is not cum TWICE, in these 5 minutes. If you lose, the punishment is….Permanent chastity. If you lose, you will never get out, ever again. You want to say no, but then she drops her dress and unhooks her bra. You agree to it, and instantly cum. Your naked bodies rubbed against each other, your lips and tongues embraced each other, and your little dick even got pushed into her pussy, cuming before, during and after penetration. What a feeling. You grab her naked ass cheeks, kiss and massage her boobs, you have the best 5 minutes of your life, and you feel like a man, for the first time in a very long time. You came 4 times. Your sister licks her pussy juice from your kick, and swallows, then plan B pill, to make sure you are really out of the gene pool. She then takes a brand new chastity cage, one smaller than ever before and pushes it on your cock, around your balls, through the piercings she made you get, in a ways that can never be removed. Before completely closing the device, she looks into your eyes and says: “Permanent chastity. No kids. No sex. Nothing. You lose it all for me” She comes closer to your lips, and milimeters before kissing you she says: “Was it worth it?”

You breath heavy and say: “Yes.” She then kisses you deeply, while closing the chastity device forever. The moment you hear the click, you orgasm one last time. This would indeed be your last orgasm ever. She then went over to the toilet, dropped the key into it, and looks into your eyes while she flushes it down.

You never had any form of sex again. You were basically a eunuch, working as a **** for your sister, without getting anything back for it. Except the occasional little kiss on the cheek. You would often stand next to her bed while she masturbates, and you while have to describe to her how she took away her brothers sex life for her own pleasure. How you had no chance and lost it all, because you couldn’t resist her.

She really never released you. You took that chastity device into your grave. And that is the end of your story. You lost it all to your hot sisters sick fetish.
