"But Jooohnnn…" Sherlock's voice has taken on that insufferably whiny pitch. "Molly's got a brand new brain for me, and it's apparently full of really lovely stroke damage!"
John cringes. "You know, Sherlock, in most households that isn't cause for celebration. And I'm fairly certain stroke damage is never 'really lovely'. Besides, you promised to come shopping with me today. The brain will still be there tomorrow."
"If you don't let me go… I'll… erm…" Sherlock pauses, thinking. "I'll withhold sex."
"Yeah, good luck with that." John snorts, clearly amused. "I haven't had a peaceful night's sleep since we started sharing a bed. I think you're making up for lost time. I can't imagine you holding out for more than a night or two. Besides, wanking was good enough for me for years, I'll make do."
By now, Sherlock's in full-on shamming mode. His eyes are suddenly impossibly wide and brimming with tears, and his full lower lip is trembling threateningly. He makes a fatuous show of sniffing loudly, as if he's on the cusp of losing it entirely.
"Look, John. I'm about to cry. You don't want to make me cry, do you?"
"Nice try, love. But you forget – I grew up with the indomitable Harriet Watson. I've had more than enough experience in dealing with feeble attempts emotional blackmail."
