This was a old Sketch Story that I decided to reupload here since before I made it a SubscribeStar exclusive, but since almost nobody has actually subscribed to me there I decided to brought it back anyways, let me know if you want to see more stuff like this with these characters :D here was the original description it had when it was first uploaded:

This is just a commission i did for someone in DA, he wanted me to draw Frisk hypnotizing Udyne and he let me come up with a lot of stuff on my own for it, so this is the result! hope you guys like it! XD

Frisk and Udyne belong to Toby Fox.
