You didn't want to know
Sherlock: *looking up from the corpse he's investigating* You're cold.
Molly: *stands besides Lestrade in a knee-length black dress with matching heels, a silk scarf wrapped around her shoulders* Yeah...because my bloody date took me at a crime scene instead of a fancy restaurant!
Lestrade: *gasps surprised* W...What, you're two dating?
Sherlock: *stands up, walks to Molly* Obviously, Graham.
Lestrade: …
Sherlock: *takes off his Belstaff, wraps it gently around Molly* Better?
Molly: Mmhh. *shoves her hands deep in the pockets* Uhm...Sherlock?
Sherlock: Yes?
Molly: *blushes slightly* Why are...uhm-
Sherlock: -condoms in my pocket?
Lestrade: *mutters* Seriously, you two? *walks over to Donovan*
Sherlock: *smirks at Molly* I think it's obvious Molly, isn't it?
Molly: You...you want-
Sherlock: Of course I want! *brushes his lips softly against Molly's, whispers* Let's go to Baker Street and I show you how much I want you!
Molly: *moans*
Sherlock: *pulls away from Molly, quickly texting Lestrade*
Lestrade: *phone peeps, reading the text* Arrest the husband. Molly and I were leaving and having sex at Baker Street. SH
Lestrade: *shakes his head*
Donovan: Sir?
Lestrade: *clears his throat* Uhm...well, arrest the husband.
Sherlock & Molly: *kissing, then quickly leaving the crime scene*
Donovan: Sir? *points at Sherlock and Molly* What's going on between the two?
Lestrade: *smirks* Believe me, you didn't want to know.
