John whined as he kept stroking himself. He needed. He wanted. "Sherlock..." He moaned, sounding almost desperate. And he was, a little desperate. He wanted to feel the man's giant cock in him again, prying him open. He wanted to see what other sort of shapes or beings Sherlock would become.

He wanted all the filthy sex they could have been having these past years.

Instead he got this. A wank in a shower and a hope that Sherlock was watching him.

He ran his thumb over the head of his cock and he cried out, unable to stop it. His body tensed as he climaxed, hips jerking forward into the touch. He whimpered as he started to come down from it.
