The Hole

Master W has many slaves. Most of them are pets who love to cuddle and to be trained, others are housemaids he keeps around himself. 
And there is Lineè. Lineè is probably his most favorit slave. A masochist to the core. She is his counterpart. 
He keeps her in the basement, tightly bound and locked up in a hole. 
Lineè now had 4 years of time to get to know her master and by now she prefers to be inside the hole, than out of it.
