>It's Mion's birthday today
>All the club members have decided to throw her a surprise party when she gets home
>they go to Shion and borrow her key
>Shion waits until they leave and finds Mion, tasing her from behind and dragging her off the the dungeon, where she's strapped into a chair unconscious for later
>retrieves the duffle bag she prepared months ago for this occassion
>changes into her sister's clothes
>goes home, careful to not be seen, and checks to make sure all Mion's friends are hiding in her closet
>goes into her sister's room, strips naked and begins violently masturbating
>the combined sensations of humiliation but also sadistic pleasure at knowing they'll think she's Mion is overwhelming
>after several minutes she opens up the dufflebag, which is filled with only the most extreme, gigantic, and horrifying sex toys of all kinds
>vibrators, dildoes, candles, whips, lotions and oils and nipple clamps
>no normal human could fit any of these items inside themselves without serious medical complications
>but she's spent months and months training, preparing herself for this nearly supernatural feat of rectal capacity
>she works her way through the entire bag over the course of an hour
>But it's still not enough, she needs something MORE to be satisfied
>She starts humping the furniture, fisting herself in the ass and pussy at the same time, screaming in ecstasy
>She "accidentally" bumps into the closet and knocks the door open, mid climax
>All of Mions friends fall ontop of her naked quivering body, prompting another even more powerful orgasm as she gleefully feigns horror and screams "NOOOOOOOOOOOOOOOOOOOOO!"
>She pauses, fully exposed, just long enough for the scene to reach it's maximum breaking point of horrifying tension
>Then she leaps up, still naked and covered in her own fluids, and runs naked out of the house through the center of town, making sure as many people as possible see her
>Eventually she breaks contact in the forest, washes up in a stream, changes into a prepared set of her own clothes and, armed with a present, returns to the scene of the crime
>She hunts down the club members, who are scouring the town looking for their friend, increasing the humiliating exposure even further than she had planned, and extracts a reconstruction of the scene from them under duress
>It's getting dark, and they think Mion may be lost in the woods, they're thinking of calling a town meeting to search for her
>This is a little too far, even for Shion, so she says that there's a secret hiding spot only the two of them know about, and she'll go and retrieve her sister
>She tells them the best thing to do is just pretend like none of this ever happened, so get the surprise party ready again and wait for her to come back
>once they're out of sight she goes to retrieve Mion
>She carefully explains everything that just happened, with a live action re-enactment for example
>And how no one will ever believe it was wasn't her, how her friendships have been ruined forever, how she'll never be able to look any of them in the eyes again
>As Mion screams and cries and chokes on her own vomit while Shion climaxes for the dozenth time, she offers her a way out
>Mion's life is over, it can never be repaired, but, just this once, she has a chance
>She can renounce her name, stop being Mion, trade places with her sister one last time
>Everything will go on, Shion is stronger than Mion, she can handle the fallout, the humiliation
>As the last jumbo sized goorilla dildo plops out of Shion's gaped asshole, Mion agrees, she'd rather die than face her friends after this
>Laughing, Shion agrees, but says there's one final condition
>It took so much time and effort to pull this off
>so many days of agonizing training
>just trading places isn't good enough anymore
>Mion has to experience the full depth of her sister's suffering to truly repent
>right here and now, the entire bag at once
>Mion begs and pleads for mercy, unable to even prostrate herself in her restraints
>Shion tells her that she only has two options, having her holes destroyed, or going out there and facing her friends
>Her dignity or her shitter, choose now
