A demonic dom

Your hard fought confidence deflates the moment the door opens and a demon opens the door. Like a literal fucking demon. At least seven feet tall, broad and sinewy with bulging burgundy muscles. Hands big enough to crush your head in his palms and claws that look sharp enough to cut steel. Horns jutting out arrogantly from his for head, brutally handsome features, and a smile of sharp serrated teeth. "Oh, I didn't order seconds. But there's always room for jello. Come on in."

You walk in reluctantly and see what you assume is your roommate cowering in the back of the room. Bent over the bottom bunk, "his" cunt glistening and gaping and plowed so deep you aren't sure if he wasn't fucked clear through. By every indication he has the proportions and posture of a bright red slime girl, but then again, you aren't exactly sure how slime genders work. Your roommate's "friend" doesn't seem to care. And the way he's eyeing you, you are starting to suspect he plans to do the same to you.

He puts an arm almost as big as your entire body next to your head, shutting the door behind you and trapping you in place. His smile grows wider, but it doesn't make him look friendlier. "Hiya. My names Devlin, the bitch waiting obediently to get fucked by me is named Ruby, or at least that's what we call her. Now I know you're new here and all, so I'm willing to go easy on you, this being your first day and all. Unless you wanna play hard to get, and then we have to do things the HARD way."

You see "Ruby" quivering in the corner and you suspect his easy is harder than anything you ever dared imagine. Then again, you really don't want to find out what HARD looks like to a literal fucking demon. So what do you do?
