Story by commissioner SnowSamurai:


1) After losing a decisive battle against the evil organization Shadaloo, Karin Kanzuki was captured and brought to an underground base.
There, she was locked in a room seemingly made out of flesh-like walls and tentacles.
As soon as the Shadaloo goons threw her defenseless body into the room, the tentacles sprang to life, lifted her in the air, forcefully exposed her vulnerable body and restricted her movement.
A Shadaloo official watching her from another room gloated: “What say you now Kanzuki? Finally found your end at the hands of Shadaloo. You should know that this prison was prepared specifically for you. And don’t worry about your cellmates. And don’t worry about your cellmates. You will find them most accommodating. ”
“I think we got off on the wrong foot here,” Karin replied, trying to the panic in her voice. “If you spare me, I'd be willing to finance your endeavors. Just tell me anything you need and I'll give it to you.”
“It's too late for that I’m afraid.” the official replied. “You have been a thorn in our side for far too long. I hope you have prepared yourself Kanzuki. Your mind and body will not be the same after this.” The official gestured to his comrade. “Start the procedure.”
Now fully overcome by panic, Karin began desperately trying to plead with him. “No! Wait! Let's talk about this! Please sto-”

2) “Aaaaah-!”
Interrupting her pleas, the looming tentacles all start making their way into her body at once.
Two thin tentacles go into her nipples and search for possible paths to insert themselves deeper into her shapely breasts.
A small tentacle with countless even smaller tentacles on it’s side starts coiling itself around her exposed clit, stimulating it to a degree she has never felt before.
Several tentacles of varying sizes and alternating girth enter her ass and easily make their way to the back of her rectum where forcefully enter her sigmoid colon.
A tentacle as thick as her upper arm and ridges going all the way across the top of it, forces its way into her pussy. The imposing ridges scrape across the sensitive walls of her vagina as the tentacle reaches her deepest parts. There, it rams intensely against the entrance of her womb, without caring about how much discomfort this causes her.
She clenches her hands and lets out a sudden gasp as the tentacles invade the sensitive parts of her body. As she is being overwhelmed by the intense waves of pleasure and pain going through her body her eyes lose proper focus.

3) The final tentacle makes its way into her mouth as well, filling up her entire esophagus causing her throat to form a visible bulge. The pistoning motion barely gives her room to breathe as the studs adorning the tentacle rub against the inside of her throat. The tentacle, longer than any man’s penis could ever be, slowly starts to get coated in her saliva as it moves in and out of her slender neck.
The tentacles in her breasts start to push in more intensely and forcibly expanding paths that were never intended to be used as such. This causes the discomfort she was already feeling to slowly turning into pain.
The tentacle coiling around her clit is masterfully stimulating her sensitive spot without reprieve. This assault sends her to climax over and over again, never being spared even the period of increased sensitivity following an orgasms.
The tentacles in her ass are going further and further into her intestines while pushing themselves against the walls. They have reach the entrance of her small intestine and are moving in and out of her ass in erratic ways.
The one in her vagina has forced open her cervix and mercilessly ravages her insides as the ridges stimulate her g-spot, amplifying her pleasure. Disregarding the fact that this is the first time Karin has ever had something enter her sensitive womb, the tentacle continues to force itself into her most delicate parts.
The intense stimulation is causing her body to spasm and her eyes are rolling into the back of her head. She is losing her sense of reason as the tentacles violate her body.

4) After a while, the tentacles ejaculate and fill all of her holes with their cum.
The tentacle in her throat fills her stomach to the brim with seminal fluid while the ones in her nipples lace her milk ducts with ejaculate.
A flood of semen fills her intestines, reaching well into her small intestine and painting her inner walls white.
An unrelenting torrent of seed enters her vagina and womb too. the sperm causes her to be impregnated several times over as the fluids expand her womb and reach her innermost parts through the fallopian tubes. All the cum her body isn’t able to contain gushes out and starts covering her toned body.
All of this finally causes Karin to lose consciousness completely.

5) Several hours pass and Karin is in a limbo between pain and pleasure, fading in and out of consciousness. Her mind has been broken and although her body has become limp, the tentacles never stopped having their way with her.
Her stomach and intestines have been fully filled by the ejaculate of the tentacles. The cum from the tentacles in her ass has also reached all the way to her mouth, causing her to continuously spit out semen from there. That is in addition to the semen coming from the always present tentacle in her mouth.
Her breasts have visibly expanded from the seed being pumped into them.
The tentacle in her vagina has managed to stretch her womb to it’s breaking point through its continuous assault, now reaching all the way to the bottom of her ribcage.
The tentacle hell that Karin was exposed to continued for some time longer. Until she was finally let go by the tentacles. Only her ravaged, cum filled body remaining.
