Mark was one of your uncles, he's known you since you were 6 years old. But he was kinda perverted/creepy with you. Especially during family gatherings/party's and stuff.

This time it was once again another family gathering and you got to the house. Mark hasn't seen you since you were 9, and now your 14. He's seen the way you've grown up and his perverted side comes out. But he hides it around everyone else but you.
