Inflatable Surprise (story) (Patreon)

Marin can't help to feel excited to finally receive a food supplement she ordered online, a miracle product for cosplayers that helps a person to be able to get into character easily (even though Marin still doesn't know how exactly), but all the mystery surrounding those pills fills her with curiosity and anticipation. Besides, what can go wrong? Since, surely, Gojo will always go to help her and save her from any adverse situation or side effect anyway.

Finally Marin takes the pills out of said cosplayer food supplement and reads the instructions and then follows it to the letter. Apparently you should only take one pill a day and one per character. For some reason each pill is assigned to one of the different anime and manga characters of the moment, even though Marin in this case asked for all the pills to cosplay Shizuku.

Then Marin swallows the pill slowly and gently, waiting expectantly to see what the real effects of the medicine will be. In the first few minutes it seemed that the pills would have no effect and that, perhaps, Marin had been scammed. However, after 20 minutes, the pills unexpectedly and untimely begin to take effect on Marin's entire body, causing her to have a massive headache as she watches her skirt begin to bubble and change shape while Marin is now very confused and disoriented.

By the time Marin manages to regain composure, most of her clothes have inexplicably mutated into a kind of strange purple plastic and continuously expanding with the appearance of being inflated, and her legs are now covered by a kind of plastic or latex stockings of a lighter shade of purple. The pill that  had this effect on Marin cannot be normal, so she becomes alarmed and tries to contact Gojo by cell phone while trying to get out of that room, something that Marin soon discovers is impossible since her skirt, having inflated and dilated too much, is now bulky enough so that Marin cannot fit through the door and even this causes Marin to get stuck for a few minutes until she finally manages to free herself from the door, but returns hopelessly to her room.

Finally, the last hope is for Gojo to respond to Marin's calls for help, by trying to call him by cell phone over and over again. By then most of Marin's body has been covered by the costume.

However, it seems that there is no luck for Marin this time, because, when trying to contact Gojo, just at that moment Marin's hand dilates and inflates, making it impossible for her to take something with her hands or call another person's cell phone because, as her hands and fingers are so inflated, it is impossible for her to dial any number on her cell phone. Finally, Marin's hand is completely swollen making her unable to hold the cell phone and it falls to the ground, frustrating Marin in her attempt to contact Gojo. Also, everyone would think that Marin would only want to call Gojo to help her cope with the situation, but in reality Marin has her mind altered by the aphrodisiac effects of the pill so she can't help but have fantasies in which she is used as a sex doll by Gojo.


By now Marin has been covered by the plastic clothes up to her neck, as her body begins to stiffen, while she continues to wait for Gojo to come and help her.

The last part of the transformation finally reaches Marin, changing and inflating her hair further, while it also changes its color alongside her eyes, resembling more and more Shizuku, the character that Marin took its design to make the cosplay. Then, at the end of the transformation, as Marin struggles and resists as much as she can the strange effects of the pill, and as Marin simultaneously drowns in ever-deepening pleasure, she falls helplessly and immobile to the ground while her hair still continues to slowly transform.

Hours later, while Marin is having the last tremors and the last hint of resistance is fading, Gojo enters Marin's room since she has not appeared for several hours. The only thing Gojo found there was an inflatable doll identical to Shizuku, which makes him ask himself a question: "what is a Shizuku doll doing there?", however Gojo has no time to play with dolls, so he decides to ignore the doll while looking for Marin without success, and while simultaneously Marin is drowning in pleasure wishing Gojo to take her home with him.
