fic recs: take thy correction mildly. kiss the rod.
With a line like "I left my riding crop in the mortuary," is there any way that Sherlock fandom wouldn't have generated a subgenre of John/Sherlock stories with BDSM elements?
Three delightfully kinky, explicit fics:
Crossed and Bound by quamquam20
John, Sherlock, and the riding crop. The imagery in this is brain-meltingly hot.
If I Fell by thedeadparrot
Sherlock is obedient at the strangest of times. John finally figures out why. The pacing of this fic is a thing of beauty: no explosive action, but a low simmering tension that gradually boils over.
Tie You Down or Hold You Up by toestastegood
Sherlock, John, and a collar. A deftly-handled take on a very intense dynamic.
Bonus: etothepii has created an entire Sherlock BDSM-verse, starting with you need someone to take care of you (but it won't be me).
