An electric cage

Draco looked arounf the room and saw where he wanted to put his slave for the night. An original product from Weasley BDSM Suplies. A cage that shocked its ocupant at random intervals at random voltages, but never enough to kill. At worst it would just keep them up all night. Draco dragged the slut into the cage and with a single tap from his wand it locked and sparks flared up all around it.

"Well you should try and get some sleep. First thing tomorrow we're headed to st. Mungos to get that fucking gag reflex removed. Can't be having that obsturcting my cock now can we?"

"Of course not Master"

"Right well good night Slut." Then without another word Draco turned and left.

Just as Hermione was starting to drift off into a light sleep she suddenly found out the purpose of the eletrical energy around the edges as she just got a slight eletrtocution. This was going to be a long night.
