This one is an experimental chapter, that's why it's not a normal numbered chapter or has the "Pupil" in the title.
--------------------------------------------------------------------------------
Opi awoke on the floor. Since she was arrested and sent to the Crypt, the monster prison, she was only allowed to sleep on the floor or, if she was a good girl, on a carpet on the floor.
The dreaded huntress, Aritimi, only visited Opi a handful of times during that week since her arrest. She didn't mind this, but the problem was that she was at the mercy of Aritimi's pets, those she shared a cell with, during this time.
Cupcake, the Rottweiler Centaur, was quite annoying. Opi always had to stay on all fours while Cupcake would pound her from behind in doggy style.
The other one, Lunariel, the Mermaid-Werewolf, was even worse. She was a futanai with a huge fuzzy cock. She often slammed it into Opi without any warning and kept assaulting her orifices even when Opi was begging to stop because it hurt.
Opi herself wasn't a human, either. That's why she was in that place. She was a hybrid. Human and Moon Elf hybrid to be accurate. And she was also a futanari.
Opi had short white hair and a strong, tall build, definitely more human than Elf since Elves are more slender. Her breasts were huge and saggy because of their natural weight, decorated with a pair of ring piercings at the nipples. She had a pussy, which was significantly less tight than a week ago, and she also had male genitals above her female one. Her heavy testicles covered her pussy, but there was nothing above the testicles. Opi's cock was reduced to a short nub as a punishment from Aritimi.
The shaft was cut short at the base, a painful reminder of Aritimi's power and control over her. Opi felt a mix of anger and humiliation every time Cupcake and Lunariel used her. Yet, she knew it was a small price to pay for her survival in the Crypt. Each night was a battle of endurance, her body stretched and used by the two monstrous inmates, their feral instincts driving them to claim their territory.
The worst part is that Opi's cock was still attached to her, just locked away from its rightful owner. Aritimi removed the phallus with her portal creation powers which meant that Opi's cock was pulled through it, and then Aritimi shrunk the portal until it was so tight that Opi's cock was stuck at the base. It was a twisted game that Aritimi liked to play with her. Sometimes she would let the cock out, teasing Opi with her own manhood, but most of the time, she would leave it trapped, a constant throb of painful arousal between her legs.
Opi's cock was erect and hard since the day she arrived at the Crypt. Aritimi didn't let her cum. Opi could maybe stimulate it by rubbing the stump, but Aritimi already told her that she would regret it if she or her pets caught her doing something like that. Aritimi is the one who decides who can cum and when.
Maybe it would have been better if Aritimi just chopped off her dick, Opi thought. At least then, the constant ache of unfulfilled arousal would be gone. But no, Aritimi enjoyed her little game of dominance, leaving her in a perpetual state of frustration and arousal.
A normal human's penis would probably suffer dire consequences from something like this, but Opi's Elf durability was just enough to keep her cock alive and usable.
As her usual morning routine, Opi got on all fours. She wasn't allowed to stand up like a human. She was a pet. The pet of Aritimi's pets, to be clear.
Opi crawled to her bowl of water and began to drink, her throat parched from the night's endless moaning and screaming. The concrete floor was cold and unforgiving against her knees, but she had got used to it. Cupcake lay snoring in the corner, her small yet muscular canine body sprawled out, oblivious to Opi's suffering. Lunariel, on the other hand, was awake in her tank, watching Opi to be sure she didn't try to do anything she shouldn't.
Suddenly, the cell's heavy door opened with a loud clank, echoing through the corridors of the Crypt. Opi's heart skipped a beat as she recognized the footsteps approaching. Aritimi, the woman who held the key to her agony and, quite literally, her pleasure. She remained on all fours, head down, not daring to look up unless told to.
"I see you are awake now," Aritimi said with a smile.
"Look at the Mistress if she is talking to you," Lunariel barked.
Opi looked up. Aritimi was naked as she always was. With her brown skin tone, huge round breasts, shapely ass, and a crescent moon-shaped patch of hair above her pussy, she looked like a goddess of lust.
"Follow me, Opi," Aritimi gestured with her hand, "We will visit another one of my pets today."
Still on all fours, Opi followed Aritimi, her stomach churning with dread.
They stopped in front of another cell, and Aritimi opened it. The inside looked more like a room rather than a cell. Colorful Japanese paintings on the walls, and a tatami mat covering the floor. On the mat was a creature Opi had never seen before, a woman with short red hair and slit eyes dressed in a traditional kimono. Her skin was pale as porcelain, almost translucent, and she had nine fox tails sprouting from her behind.
"She is Reiko," Aritimi introduced the monster girl, "She is a Splitsune. Reiko, show her what you got."
Reiko stood up and removed her kimono to show her bare body. She looked mesmerizing, but her most prominent feature was her nine cocks, each having a different size.
