"This isn't fair."
"Really?" John quirked an eyebrow at the other man. "You may wish to consider that statement from the viewpoint of your long suffering lover."
Raising both his arms in a deliberately sensuous move, he ran his fingers through his hair, his eyes never leaving Sherlock's face.
Sherlock opened his mouth to speak, but John didn't give him the chance.
"I told you to be careful, warned you Perkins was unlikely to make it easy for you." Lowering his hands, he wiped them suggestively on the towel, rubbing his palms down the front of his thighs.
"But…"
"But you had to chase him over that roof didn't you? If you wanted things to be fair, you should have listened to me and waited for the police."
With that John turned away, dropped the towel, and treated Sherlock to a view of his bare bottom walking slowly towards their bedroom.
"But John," Sherlock wailed. "My leg's broken!"
