Chapter Text
Despite Sherlock’s teasing, Mycroft was not one to give into every silly craving his body demanded. Being the smart man that he was, Mycroft knew that a few treats on occasion would help him to resist the urge to binge on the constant biscuits and cakes present at his countless meetings. Mycroft’s favourite indulgence was the Spanish donuts, Churros, which a small stand in a nameless park served. He would order one and savour the fried dough powdered with sugars as he sat on a bench and observed the people walking past. However, with his younger brother engaging criminal masterminds and The Woman of all people, Mycroft found himself needing that particular comfort food more than his bi-annual luxury of the past. And so every Thursday afternoon that wasn’t filled with conference calls and last minute trips, Mycroft found himself walking to that familiar stand and ordering his treat.
This Thursday Mycroft was eating especially slowly, as he had been out of country the previous Thursday. As he watched a young couple holding hands (female was uncomfortable as her boyfriend animatedly tried to persuade her of something, a threesome Mycroft deducted), someone sat silently beside him. Mycroft chose not to look over in case his action encouraged the person to try and start a conversation, god forbid. Swallowing the last bite, Mycroft drew his fingers to his mouth about to lick the last remains of his sugary relief away. Before he could, a hand grabbed his wrist before Mycroft turned and came face to face with one Jim Moriarty.
“I missed you last week,” the man smirked, “but I suppose I shouldn't have organized the assassination if I didn't want you to go running to fix it.”
Mycroft gave a sharp tug of his arm, which did not cause Jim to release his wrist, before politely answering, “One would think you’d foresee my actions since I spent much of the last year trying to keep him alive.”
Jim pulled Mycroft’s hand towards his mouth before licking at the thumb. Mycroft, determined not to give the satisfaction of a reaction, sat stone still as Jim sucked the sugar from each of his fingers. Once Jim pulled the pinky finger out of his mouth with an obscene POP he twisted his fingers from Mycroft’s wrist to intertwine with the other man’s hand.
“If you wanted I could give you a little hint as to Daaaaaddy’s next naughty plan?”
Unable to stop himself, Mycroft’s eyes flickered to where Jim was holding his hand and rubbing his thumb slowly over Mycroft’s own thumb.
“Seeing as I missed my treat last week and you finished it off this week, it would only be a fair trade if you were to do so.”
A look of glee flashed on Jim’s face before he leaned in so his lips brushed Mycroft’s own when he spoke, “Daddy’s going to introduce krokodil to America through a certain over the counter drug. Buuuuuut if you agree to walk in this lovely park with me for the next hour I’ll let you know which oooooone.”
Mycroft’s only response was to raise an eyebrow and stand up slowly, “Lead the way Mr. Moriarty”
Jim practically jumped to his feet before running his hand down Mycroft’s arm and once more intertwining their fingers.
