Sherlock grunted and strained past the knot, which came out with a slurping pop. The rest of the dildo slipped out rather easily, in a loud, messy slurping nose and a rush of lube- Sherlock had used most of one small container just to get it inside of him.

When he tried to stand, he found that he couldn't and he fell to his knees anyways. His legs were weak, his arse was still leaking more lube.

"Mmmgggg.." Sherlock couldn't speak any more. He was too deep, too lost. He could feel how open and leaking he was. He heard John, but he couldn't respond, just a soft nod. He was a mess, covered in come and lube, and full of come and lube and piss in his mouth and throat and stomach.

He could feel John press inside of him, and he was so wide open and full of lube that John just slipped inside with almost no resistance of all.
