So this is what I wrote instead of my nano novel. its 2am and I took a bit of nyquil before editing, so if there’s errors, I’ll probably get them in the morning:

Not One Iota – Stuck with a hard on and not wanting Sherlock to know, John takes refuge in the alley. Of course Sherlock knows anyway.

John leaned against the kitchen counter. This was ridiculous. He was a fully grown adult male; he knew how to handle an erection. But Sherlock had been around all day and if John hurried up stairs then Sherlock would know exactly what he was doing. Same if he suddenly took a shower in the middle of the day.

Taking a deep breath, he glanced into the front room, but Sherlock was still on the couch, fingers steepled. He’d hardly moved and John wanted to scream in frustration. Of course he could just go take care of it anyway, no matter what Sherlock might think, but the fact it was that git on the couch putting him in this condition was nearly too much as it was.

He made a show of opening the fridge and only found the kidneys from two days ago on the shelf. Good, an excuse. “Going to the shop,” he announced, striding out of the kitchen and grabbing his coat. His flatmate, like usual, said nothing.

Outside was chilly, but not nearly cold enough to take the edge off. He should go down to the pub, have a pint, find a girl, but that wasn’t what he wanted. Closing his eyes he turned down an alley and leaned against the bricks. His hand stole down to press his heel against his erection.
