Torture Device

Isha was a young lizardfolk mage wandering from town to town. Because of her time in human lands, she had been appropriated to the point where she was human at heart. Despite this, she was aware and worried about the intimidating aura her most definitely not human, 7’6” lizardfolk body gave off. She spent most of her time studying magic, but occasionally visited bars. On one such occasion, some very unusual events occurred.
Isha walked out of the alley bar having finally lost her buzz. Just as she was leaving, however, a man in a black coat walked up and suddenly, she fell asleep.
When she finally awoke, she found herself in a dungeon.
Lascuras was pleased. He, as a powerful mage, could destroy any enemy, but his weakness in illusion meant giving them real torture was difficult. Now, he has the real threat for rival mages of being devoured.
Isha found her cell void of any light but a small magical ceiling lamp. She waited for several hours, until a young man was thrown in with her.
This wasn’t good.
Over this period of time Isha had grown somewhat hungry. She was no murderer, but at a point instincts would force her to consume the nearest meat she could find. As for now, all she could do was wait.
They sat there for hours, the man quivering and Isha struggling in vain. Every couple minutes, she would begin to move towards him only to stop herself. Until one time, she didn’t.
Meanwhile, while considering logistics, Lascuras found a problem. There was nowhere the beast could defecate. Problem turned to solution, as a smile ran across his face.
Isha found a bit later the same black-robed man in her cell, and the same sleeping charm took effect. When she awoke, she found herself unable to move from paralysis. Ahead of her she saw that there was an individual stuck beneath her weight! From what she could see, his head was right under butt. Obviously, this was very concerning. However, she couldn’t cast magic or even move, so when nature’s call came there was nothing she could do about it. Over 100 pounds of shit flowed into the man.
This continued for years, until finally Isha was set free at her captor’s death.
