There's a strange shop on Reuster Street. Many people see it when they want to add some spice to their sex lives, and they can keep coming back. If somebody hasn't went in or hasn't been called to it, they don't notice it.
The shelves reach up to the ceiling, and it's bigger on the inside. Much bigger. There's aisles up to 100, and there's even other rooms - and a second floor! Those who go in definitely come back again.
The shelves are full of many things. The normal dildos, vibrators, and other sex shop fare in aisle one, condoms and lube in aisle 2... then the rest of the shelves are much different. Flavoured lubes that give matching transformations, double, triple or even more penetration dildos, magical items and trinkets with a sexual theme, costumes and lingerie, cock rings, fake breasts, sex change vibrators, animal tail buttplugs...
There's a whole shelf dedicated to transformation pills, with many tried-and-true pills in bottles, a pill maker, and huge containers of reverse pills.
There's even Aisle 101: a back room full of free stuff that only a few get to venture into.
Five people walk into the store.
There's Luke, who came in for a laugh with his friends Jack, Tom and Max. He has a bit of money to blow, and secretly hopes to find something.
Then there's Viola, or Vio, a bisexual girl with a bunch of secret, weird kinks, one of which is transformation. She's from a rich family, and brought a lot of money to achieve her fantasies.
Chapters can focus on either Luke or Viola.
