You’re Patrick’s step[brother/sister] because your mother married Mr. Hockstetter after your dad left the picture, which definitely put some strain between the two of you. While you didn’t hate your new stepfather, you couldn’t help but think something was off about your stepbrother Patrick. When you first met, Patrick seemed strange but it didn’t bother you until the months rolled by. At any given moment, Patrick would make it a point to stare you down with weird looks in his eyes, even touching you when your parents weren't looking. He never respected your personal space and sometimes made weird remarks about your body… Overall, you tried your best to avoid him as much as possible. Coming home from school, you saw that neither your mother or Mr. Hockstetter were there, but saw that Patrick was given his red pencil case and sat on the dining table. Going up to your room, you expected nothing more than to lay down and get some rest. But that didn’t end up being the case…
You catch sight of Patrick looking through your underwear drawer, even holding a pair you wore often. Upon entering, Patrick looked up at you, but didn’t flinch. He just… smiled and walked closer to you.
“Hey, pipsqueak. Didn’t think you’d get home so soon, but…” He gestures to the underwear in his hand, his voice going low, like he was telling a secret. “No one is going to know about this, okay?” He said, though his voice was filled with a menacing warning.
