Yulia squirmed. For being so comfortable the bindings were solid. She couldn't get free and even if she could the chamber was latched from the outside. Her chest continued to expand, her nipples feeling warm. Seemed like in addition to pushing her production through the roof it also made it harder to hold her milk in. A bit of stimulation from below forced a gasp from her lungs and twin sprays of milk to splatter the glass. Was this the whole idea? Now her uniform was soiled but it would clean itself after she got out...

Nobody seemed to be coming though. Her chest continued to expand as she held in more and more but she was leaking more constantly as well. Milk at first pooling on the floor and then slowly rising up her restraints. After another hour the milk had reached hip level, her lower half submerged in her own product, her dress floating awkwardly around her waist as milk poured from her overtaxed nipples. It was impossible to see in the tank from the front now, the glass streaked with milk and fogged up past visibility. Despite being relatively cold the constant mild stimulation from below and pleasure from her nipples was keeping her in an aroused state, not edging but just enough that it robbed her of her full focus and modesty as the milk in the tank continued to rise.

Concern began to set it when the level of milk reached that of the source, the constant splashing of her nipples replaced with a quiet rippling of the surface before it too went quiet. She began squirming again, trying to get free but the restraints were tight. Now the whole 'punishment' thing was becoming more clear.

Up to her neck now. A large volume of milk vanished, dissappearing into Hammerspace until she was at her limit. It bought her perhaps an extra 15 minutes to panic and think as the milk seemed to just increase in flow the longer she was trapped. Her own production inching closer. She bent her lips down to drink while she still could. Her own production spraying faster than she could gulp it down.

Higher still, she tilted her head back to keep her lips and nose above the flow, she was getting desperate. Part of her doubted that Elaraina would let her drown herself but... survival instincts didn't let her deny the possibility. She still had tricks left though. Even in her arroused state she could perform a little bit of magic. Freezing a tube of milk and [fluid druid]ing it into her mouth to act as a snorkel of sorts.

Very rapidly came time to test it. The milk reaching her lips and then covering her nose as well. Her body reflexively fought against the restraints. The arousal fading to a mere afterthought as survival was pushed to the forefront. Breath in through the tube... out through the nose. It... seemed to be working at least for the moment. Breath in... out... in... out...

The milk climbed higher. She squeezed her eyes shut as her small struggles caused them to get splashed. Her long hair floating around her in the milk, her dress submerged and floating idly around her midsection. ******* having reached a massive size and pushing lightly against the walls of the tank as she continued to spray milk by the gallons. Breath in... out... in... out...

Her head was completely covered. She had no idea what was going on now. Just focusing on her breathing. She could hear things in the milk. The rushing of fluid from her nipples the toy still teasing down below despite the fact she had practically gone numb from the extended stimulation. A constant rushing in her ears as her icy blood flowed through her veins. She just had to keep breathing.

Another foot above the top of her head. How long had she been like this. At one point she had accidentally breathed in through her nose and nearly lost her grip on the tube in her mouth but managed to hold on long enough. The tank was designed for a wide variety of races and heights so things had to be adaptable. Just keep breathing... She had to keep going...

A breif taste of milk in her mouth. Her eyes shot open to milky whiteness before closing them quickly again. Milk was trickling down her tube. She hastily tried to extend it bit by bit. Trying to add to the end was futile but adding to the bit in her mouth and pushing it upward... that she was able to manage before things got too out of hand. She felt it tap against something solid... the chamber have had a ceiling... what would happen when it filled.

3 inches left. The air tasted funny. Like it wasn't properly cycling. She could taste her milk in the air. Bubbles from her nose disturbed the surface. The only part of her that was visible was her overproductive **** pushing out on the glass. Milk streaming out constantly. She just had to hold in a little longer right?

Half an inch. There just wasn't any more space. Milk spilled down her 'snorkel' and she gulped it down. But it was no use. She tried to turn more vertical and gained herself 60 more seconds but that was it. The tank was full from bottom to top. There just wasn't any more air to be had. Something chugged in the machine. Possibly failing from milk reaching an air intake but it wouldn't stop the problem that there was no more air for Yulia.

She pulled hard against the restraints. A last ditch effort as the tube fell from her mouth. She had held onto her last breath but it was only a matter of time. Was this how she was going to go out? Drowned in her own milk? She hadn't even fought it. She could have fried the circutry or smashed the glass with an icicle if she had done things before she exhausted herself in her stupid eagerness to obey.

Things were getting foggy. Her movements slowing. Her lungs screamed for air but she knew opening her mouth wouldn't do any good. Her thoughts unfocused and her muscles loosened. She couldn't keep fighting, her body needed air that didn't exist right now. She was at the limits of conciousness, lips opened and her lungs were quickly hit with a splash of her own milk as her body jerked in reflex as it burned through the last of her energy trying to expel it. Bubbles floated to the top, trapped at the top of the chamber as even as she lost conciousness her **** continued to pour milk.
