You wake and wish you hadn't

You wake up and wish you hadn’t. Every part of your body aches. Particularly your back and shoulders. You try to stretch them out and realize that you can’t move. Your eyes flutter open and see nothing but a mass of white. It takes a moment for you to realize that you are looking at the the plush top of what seems to be a medical bed. A sick feeling comes into your stomach. You laboriously turn your head and find that you are indeed in the fourth floor dungeon. Your memories flood back. How did he see me? You try to move your arms and legs again and find that your wrists and ankles are securely strapped to the bed in a position that leaves you...butt up. Oh, sweet lord...

“Finally awakened, my dear?” a voice asks from your other side.

You turn your head and spot the old man who’d been at the control station. “Who are you?” you ask. “Let me out of here,” you demand weakly, tugging at your restraints.

The old man smiles gently. “Oh, I don’t think so. It's not often I get to play with a young woman.” He sneers. “Just men and boys that piss Yoshida off. Always keeps the women for himself. You’d think he could throw one or two my way but noooo. Selfish. Selfish is what he is.” ‘Play with a young woman?’ You didn’t think it was possible but your stomach sinks even lower. The madman goes on. “He thinks that just because I love butts I’m okay with any butts! Can you imagine anything more ridiculous. I mean...” He spanks your ass hard with one hand. “This is a butt! Not saggy or flat or...hairy, god forbid. A real peach of an ass!” He rubs his hands together. “Oh, the things I am going to do to that ass.”

Holy fuck! “Help!” you scream. “Anybody, please!”

The old man just laughs. “Do you think Yoshida’s private dungeon wouldn’t be sound-proofed? Scream all you want, my dear. I don’t mind. Now, what say we get started?” He slaps his head in distress. “Oh, I almost forgot. My name is Bunishichi. But you can call me Doctor B.”
