I remeber (vaguely) a fic in the supernatural fandom, where someone (probabaly same and/or dean) were kept trapped in a room by an anal locking pear that was chained to the floor.

Ii have a sudden desire to see this method used to keep Danny restrained instead of tying him to a chair. It would be harder for Electra to kidnap him, and along with some wrist restraints would make him pretty helpless to escape.

With evetual sexy times and some soothing and caring done after if sexytimes is done.
