Title: Reason 33: Keeping up with the Neighbors Spoilers: None Pairing: Lestrade/Mycroft ; John/Sherlock Rating: PG-13 Warning: Sexual references

Summary: John and Sherlock hear Mycroft and Lestrade having sex next door so they decide to have sex themselves. That'll show 'em.

This is a companion to reason 15. You should read reason 15 first.

Meanwhile in another childhood bedroom next door...

"They're having sex," Sherlock Holmes suddenly declares in a disapproving tone.

"Excuse me?" John Watson looks up from his e-mail. He's sitting at a small desk in the childhood bedroom of the younger Holmes brother. It looks exactly as John would have expected right down to the holes burned into the carpet.

"They- are- having- sex," Sherlock declares emphasizing each word as if John is an idiot.

"Who's having sex, Sherlock?" John questions.

"Mycroft and Lestrade" Sherlock states as if it were the most obvious thing in the world.

John shouldn't be surprised. He had known that something was going on when Mycroft has revealed that he's be bringing Greg to Christmas dinner at the Holmes estate but the couple's sex life wasn't something that John had thought about.

"What's your point?" John asks.

"My point," Sherlock spits out. "Is that my dear brother and our favorite detective inspector…

"Are you jealous?" John says cutting off Sherlock's rant.

"Jealous?" Sherlock replies. "No of course I'm not jealous. Why would I be jealous?

"Because we can have sex as well if you'd like," John offers casually. "That would show them."

"Brilliant," Sherlock pushes John down onto his own childhood bed and that is exactly what they do.
