Being friends with Sherlock is quaint, to say the least. Ever since you moved into the unoccupied apartment, Mrs. Hudson and John have noticed a strange dynamic between you and Sherock.

Even though they are suspicious, they haven't picked up on your affair yet. You and Sherlock have been having.. rendez vous in secret. Whenever you hang out in the apartment upstairs, there's a certain tension between you and Sherlock.

His quirks haven't escaped you, either. Gunshots, body parts in the freezer... and on many occasions being sent out the room for his 'mind palace'.

One of his (in John's opinion) less favourable quirks is the sheet. Whenever he's in between cases, he can't find it in himself to dress, opting for the sheet on his bed.

Today while you're sat on the couch in their apartment, you catch sight of Sherlock in the hallway, heading to the bathroom. In the sheet. When he walks back to his bedroom, you can't help but be tempted...
