“I require your  assistance John,” Sherlock opened the bathroom door.

“Sherlock!” John had his pants half up. “Knock, you bloody bastard!”

“No, no, you won’t need your pants. Or trousers.”

John stared daggers at his flatmate. “What do you need that won’t require pants?” he asked evenly, mentally counting to twenty.

“Come to my bedroom.”

John closed his eyes and upped the count to forty. “I’m not gay, Sherlock.”

“A man’s life depends on this, John, I need your assistance. I need to see how long it takes you to achieve orgasm.”

The mental count went to eighty before John opened his eyes. “Really?”

Sherlock gave John one of his looks. “It must be you, I cannot keep track of the various factors while masturbating myself. Besides. You need to be bound.”

John stared at him. “You want to tie me up and then do what?”

“Masturbate you. Do keep up, John. My bed is closer.”
