As much as Sherlock would like to be open all the time so that John could shove that Demon cock in him whenever he wanted, but he was pretty sure that he couldn't have that cock in himself all the time.. it was just too big.

All Sherlock could do was grunt in response while John fucked him hard and fast. It didn't take his Sir long before he was filling his arse with so much come it was leaking out, mixed with the lube that was already there. He moaned and let himself be thrust around while John fucked and filled him.

"Nnnnnn..." Sherlock whimpered, almost crying out when John pulled out. He'd been so full of his Sir, and how he was empty once again. He could feel the hot come hitting his back, ropes and ropes of it, John seemed to have massive amounts of his seed, and it was all over very single part of him now.
