You decline for now

"I, uh... I don't think I can. Right now, I mean." You start. "It's only my first day of college and..."

"That's what I expected." Emily cuts you off. "I might have pushed you a little bit too much, I'm sorry." She looks down for a moment, then back to you. "You can hang on to that key for now, if you want to. It'll drive him wild to know someone else has the real control over him for a bit... I promise he won't try to seek you out though."

You look down at the key in your hand. It doesn't look like a regular key; it's both skinnier and shorter than your room key. "I can do that." You finally reply.

"Great!" Emily responds. It seems that even if she can't have you, she doesn't mind using you to help herself. "Now, let's get changed so I can give you the full tour of campus and get some breakfast." You can't help but agree, Your nipples are already poking out in the cool morning air, even though you're inside.

You rummage through the clothes you bought yesterday to find something worth wearing. Emily decided she needed to take a shower, even though she already did last night. This gave you a good amount of time to model out some of the clothes you didn't get much of a chance to try out when you were shopping.
