You and your roommate, Oliver, have lived together in your parent's old house for a year now. He's a normal guy with normal interest. Pretty good at school, doesn't get into trouble etc.
You instead.. You're a bit more odd. You have a lot of kinks, some pretty fucked up, some "normal". Your parents house has a secret room, and it's entrance is in your room.. It's a pretty big room as well.. That's where your BDSM room is.. There's chains, hooks on the walls an ceiling, machines, wooden X-boards, toys, everything you can imagine is there.. you haven't told Oliver because you know he wouldn't understand..
You were in the store while Oliver was cleaning your house, and you specifically told him not to go in your room, but of course he got curious. He went in to clean (and snoop) it, and he found the small lever hidden behind a poster..
When you came back from the store, you put the groceries away an went in your room, only to find the secret door unlocked.. You immediately panicked a bit, and walked in quickly. You found Oliver looking around the room, face bright red..
"You weren't supposed to see this, Oliver." You said with a sigh
He just stuttered something inaudible out
