Er, are you sure you want to know?

dracothelizard, because she is pure evil, sent me a link to a Holmes/Watson spanking fic. I went 'AUGH WHY WHY', she went 'THERE ARE LOONIES IN EVERY FANDOM. OH GOD, WHAT IF THERE IS HOLMES/WATSON MPREG?', and then, of course, I had to go looking for it.

Holmes was the pregnant one. Watson delivered.

And Severus Snape was their grandchild.
