Inhibitions by E4mj reviews
Harry with no inhibitions could mean a lot of things get done quickly. Snape's POV of a potions accident with interesting effects. A lot of things are left unexplained: It is JUST a ficlet. A little thought that came to me after reading a potions/disaster story, un-developed mostly. Rating for swears.
