"John!" Sherlock screamed.
John could hear him in the other side of the room but chose to use the muffling effects of the door and rushing water as an excuse not to reply. He was tired and just wanted to ease his nerves by taking a nice hot shower before Sherlock dragged him to another place with a farfetched solution to a case just to ease his boredom. He admitted that it did give him sort of a rush at times, but lately there had been no breaks.
He leaned the side of his head against the shower wall and relaxed. No one, not even Sherlock Holmes was going to stop him from his brief moments of serenity
Suddenly, he remembered something. He had forgotten to lock the door. John walked out of the shower, hurrying to the door in an attempt to lock it; as if on cue, the door to the bathroom opened at the exact same time.
"Sherlock!" John exclaimed.
"What?" Sherlock looked over at John, seemingly unfazed by neither his nakedness nor his anger towards the taller man. "I called you."
"Get out!"
"We need to go," he said, still not getting the hint. "I got a new lead…"
Sherlock's voice trailed off when he began staring at something, eyes widening slightly the longer he paid attention to whatever it was.
"Sherlock…?" John breathed out as began to get more nervous. It wasn't long before it quickened as he realized what Sherlock was staring at. Utterly mortified, John brought both of his hands up to cover his member.
"Well," Sherlock said. "S'a lot bigger than I thought it would be."
And with that, he left the bathroom calling back, "We leave in a few minutes!" leaving a red faced John standing alone in the bathroom.
