Lady Ruby Gathered her clients to show off a new creature in her menagerie, something she had specifically bred to serve a purpose. Her clients consisted of noble and notable people. Often sharing some eccentric tastes or dark secrets. They sat around the edge of her showroom, She stood in the middle with three of her tiefling pets to aid in the presentation. “Ladies and gentlemen, thank you for coming once again, I assure you my newest project shall be as enticing as ever.” She held up a glass jar sealed over the top with a simple paper cover. “In my hand I hold a monster referred to as a black pudding, most commonly known for their amorphous shape and corrosive properties. They are perfect for a trap to hide in the dark little places you don’t want seen. Though, my newest form of them have been specifically bred to be a less lethal trap.” A murmur spread between the gathered guests. “Utilizing their ability to absorb fluids and expand, potentially infinitely, these have been bred to target certain parts of the body and incapacitate it’s target.” She stepped aside and her guards pushed forward the first pet for a demonstration. 
M was a well developed purple tiefling with hair chopped short on her head. The kobold guards pushed her to her knees on the stage and stripped her cloak off. Underneath it her hands were shackled together in front of her and a chastity belt fully covered her lower half. The guards then fixed a clear solid cone around her head that extended above the top of her hair. Lady Ruby stepped close and poured the black pudding into the cone. The ooze darted at M’s lips and nostrils silencing her panicked scream, instead only allowing a gargle to escape as it fully disappeared down her throat. As it slid down her throat a tightness grew in her chest as it expanded on the way down. M gasped for air as the ooze settled into her stomach, but it quickly started to grow and thrash, visibly pushing out her growing belly. The onlookers witnessed her shock and whining as the ooze continued snaking its way through her intestines, visibly stretching her stomach further. In less than a minute M looked beyond morbidly pregnant. The ooze was stopped only by her chastity belt and looked for another direction to grow as it stretched her to her physical limit. It pushed its way back up her throat and gurgled out of M’s mouth and nose, filing the base of the cone and slowly rising, obscuring her panic stricken face and finally slowly bubbling over the edge of the cone and onto the floor. “You may be able to observe that she’s still breathing, after a point in its growth the ooze becomes air permeable and the subjects are still able to breathe, thus making it less lethal. Given enough time though the ooze would duplicate and slowly suffocate the host. That was just the basic pudding, my first stage, but I will bring you a more improved version!” She held up another jar sealed with a solid lid and gestured for her next pet. 
C was made to shuffle forward, a short orange tiefling with a very curvy body. She was left standing and when her robe was removed she was left wearing a tight latex dress that enveloped her whole body down to the knees that barely left her with the ability to shuffle. The guards strapped a tight leather mask to her face that only had slight slits for her nose. Ruby held up the next jar, “With the addition of a glyph tied to the opening of its container we can energize the black pudding, causing it to behave even more aggressively, and to be able to exploit any gap in an intruder’s armor. She turned the lid open slightly and the smoothe liquid began to thrash like a tank of eels. Ruby held it away from herself before she wrenched the lid open and cast the ooze at C’s feet. The ooze crawled its way up to her knees and under the hem of the latex in an instant. She let out a scream muffled by the mask over her face and fell to her knees. She clutched and scratched at the dress as her growing belly pushed out and stretched the already distended material. The oozes expansion was limited by the encasement of its host, so it spread at an even more rapid pace. “In a circumstance such as this the ooze will spread under the target’s clothes and seek out more places to expand.” as if on queue the tentacles flicked out from under the dress and pushed on it from the inside, filling in even the smallest gap and crushing the host inside. C fell onto the back her arms thrashing in a vain attempt to somehow free herself. She clutched her throat as ooze began to bubble out of the nose slits in her mask. Ruby ignored her and continued her presentation, “Now you may wonder how to free the victim from this creature. I've made a chemical that forces the pudding into a hibernation state, splitting into its smallest possible parts and passing through the host's body like an egg.” She poured a drop from a flask onto both of the demonstrations and the ooze began to fizzle back into the host's bodies, leaving both of them gasping and sputtering for air. Lady Ruby leaned down and unfastened the mask on C’s face and pulled an egg shaped black ball from her mouth and presented it to her guests. “The black pudding needs a week to hibernate before it’ll reconstitute if allowed to float in nutrient rich fluids. But, there is another application of my lovely little creation.” 
Her guards pulled back a section of the floor to reveal a grate in the ground. Her last pet for the demonstration stepped forward. A was a green tinted thin tiefling, she dropped her robe and stepped over the metal grate. The energized pudding shot from the grate and wrapped around her legs, pulling her to her knees. An ever increasing amount of ooze enveloped her body, wrapping tightly over her skin as it filled her on the inside. Her stomach thrashed and swelled with both her womb and intestines being stuffed full. She spasmed as the ooze bubbled up from her throat and spread smoothly over her face. The tentacles calmed themselves and formed a tight layer around her swollen body. The rest of the ooze retreated into her body, un-restraining her. In a weird unnatural way her body stood up, the pudding was controlling her body. It walked over and grabbed the edge of the cone on M’s head. The belly of the host contracted and a ooze poured from her mouth and over M’s head, subjecting her to more ooze. After a moment the Host stumbled over to C lying on the floor, falling over her. C attempted to struggle away but her face was soon gripped by yet more ooze, crawling its way back down her throat. After pouring the ooze onto its two victims A’s possessed body stumbled towards Lady Ruby who, with a flick of her hand, magically lifted her into the air. “This final form of my creation encases its first victim into a form similar to a thrall, that uses its expanding mass to infect other victims with the more standard form of ooze.” She paced around and dropped the liquid to deactivate the pudding on each of her pets, letting each of them pass out exhausted on the floor.
Her guards slowly removed her pets from the exhibition hall as she stepped to the center of the room. “So, who’s interested in purchasing one of these lovely specimens!”
