Summary
Seeing a murder in an alleyway was the last thing you ever thought you’d see happening in your small town WestonVill. Having the murder disappear over night and the murders move in across from you was also something you’d never expect to happen.

If you could only figure out what he wants from you.

Summary
New kinktober! One chapter a day for the entire month!!! With a list I made myself, very excited to show everything I've written.
Just like the other ones every chapter contains some form of hypnosis/mind control/brainwashing. I'll do my best to tag but i can't tag absolutely everything so look at the warnings at each chapter or in the table of contents.Series

Summary
We're back with another year of Inkwhumptobertale!
And this year, we have another twist: another list! That's right: every day, I'll be facing the challenge of eight different unrelated prompts, and I'll have to do my best to cram them all into the story, somehow. Admittedly, there is a low chance of me actually doing that, but I am obligated to use at least three prompts each day, and I'll add more if possible. I'd like to do at least one day fitting all eight prompts into the story at some point in the month, though. So..prepare for chaos!
These characters are not mine!

HI all!!
I am back again with another Inktobertale! I got a late start and no promises I will finish. But I am trying to do as many as I can!
I am quite busy this month as Halloween is my favorite holiday! What better way to celebrate than with my favorite little guy!
Characters may be OOC but I will do my best to portray them as well as I can!
Ink was created by the amazing Comyet on tumblr!
I hope you all enjoy this year and thanks to everyone who has left me comments in the previous ones! ^^

Summary
Коли на вулиці сонце припікає гірше за борги по навчанню, а єдине місце з працюючими кондиціонерами оповите університетськими плітками про неминучу погибель в ньому, залишається лише одне: забити та відпочивати в тиші і прохолоді, допоки твій спокій не порушить єдина людина, чиє сердце з першого знайомства належить тільки тобі.

Summary
You'd never expected to be one of those people who bonded with a random stray, and if you did, you never expected it to turn out like this. The tiny... blob of an animal was cute, affectionate, and melted your heart before you'd even named him. Unfortunately, not everything is as it seems. You've met this lovely creature before, and he definitely remembers you...

Summary
As you walked you failed to hear the screams of terror of a bus going over 100 miles per hour and the sounds of it starting to bust down- it speeds near the sidewalk—the people in it shriek. Their blood curling screams didn’t occur to you, your headphone quality being way too good. Your shoulders relaxed as you stretched your limbs; very much unaware of the danger and pain that would very much make your life way more miserable. You should move out the way. But- likewise, you are unaware. Of death flickering and time excited to cut your strings.
The bus is almost out of energy- and has been stopped.
Or so people thought.
It began to tilt- right where you were very much slowly walking. Andddddddddd—
It didn’t crush you to death.

Summary
You need to stop staring at him.
You could spend an eternity just watching him sway his hips along to some overly cheerful pop-song bubbling from his phone, (especially because Stretch is gone for the weekend working on something with Undyne, which means he can’t tease you for getting distracted by the cooler Serif,) but you know that eventually Val will catch you ogling him. Forcing your attention elsewhere, you help out by finding a pot, using the stepstool in front of the sink to be able to reach for the cold handle.
(or, in which the reader falls victim to one of Stretch's traps set behind for his brother, and it leads to some shenanigans with your boyfriend.)
