Sherlock looked them over. He was too wound up, he didn't want to wait for as long as it would take to open himself up for the biggest one, and the thin one wasn't as satisfying, it was more for John to tease him with- it wasn't as fun to use alone.

He decided on one that he hadn't pulled out, it was fairly new, so it hadn't gotten much use as it was bought right before John became pregnant again. It was between John's demon size and his human one- thick but not so thick that it took forever to prep for.

He put the others away and then held it up for John's perusal. It was a very deep red, almost blood red, a bit curved, with a thick head and a small almost canine knot at the base to keep it locked in.

He could... keep it in.. he realized.. And that made him moan.

'Does this meet with your approval?" He asked with a sly grin.
