Sherlock licked his lips when John put the plug down next to him. It was a very basic plug, black, in an almost diamond shaped design. It had a very wide base, then a short area where it was much skinnier, then it flared back out to about as wide as the base, and then it tapered to a rounded point. It didn't need to be long, it just needed to be wide to keep Sherlock nice and stretched.

And it was.

He moaned and closed his eyes. Sherlock loved it when John talked dirty to him, but even more when he praised him at the same time.

"Ahhhh!" The lube was cold at first, it was a bit of a jolt to the very sensitive nerves around his opening> But with a bit of time and John warming it with his much warmer body temperature, it became quite nice quite quickly.
