Summary: With your parents away for the weekend, you - a 16 year old high school boy - are finally finishing assembly of a shrinking machine you bought to fulfill your girlfriend’s fantasies - and finally lose your virginity. The only hitch is you have to babysit your tomboy little sister - 11 year old Becky - but luckily she’s fine with leaving you alone to work on your boring project. Unluckily, both you and your parents have forgotten her birthday is tomorrow, and when she comes back into your office after you run your first shrinking test, she doesn’t realize that you’re shrunk and pauses your regrowth - and worse, begins changing the settings that affect you, muting your voice and worse. When she finally does notice you, thanks to the only context she has for shrinking devices being from a Tiktok video where it’s used on a dog, she assumes that you’re her surprise present for her birthday… Her new pet.
And, being a tomboy, she’s more than happy to finally get to play games with you again.
You’re not going to like those games.
The story focuses on humiliation at the hands of your younger sister, who is just playing fun games and pranks with her new pet. With your ability to protest taken away, it won’t take long for those to spiral to a bad place.
There’s no real fetish content in the first two chapters, the first is just setup for the story and the abilities of the shrinkbox, and second is trying to stop your unaware sister from making things worse. This story will focus mostly on odor content, first feet and foot worship with a heaping of humiliation, then some ass and fart stuff later. Some transformation-adjacent stuff too. Tags will be added as they become relevant.
