Jake finds a Breathplay tank on eBay and buys it. The tank automatically fills with water and locks the user inside for a set period of time. After trying it out himself, he lets Susan have a go and greatly enjoys watching her drown due to him having set the timer to 4:00 min.

This story is part of my Smut-Shot series. These are generally quite short and have very little, or no plot, but have therefore all the more extreme and satisfying content that I wrote to satisfy my own kinks to their greatest extend.

It is therefore purely intended to be sexually satisfying to read.

WARNING! This story contains very intense Breathplay involving complete drowning, and is therefore only intended for those who are into it!

So if you're interested in this kink, I hope you enjoy reading this story just as much as I enjoyed writing it!


Jake always loved Breathplay. Already in his early childhood he did experiments to see how long he could hold his breath. But just one year ago did he realize that his ‘interest’ is actually a sexual kink. This encouraged him to do even crazier experiments, until eventually, he stumbled upon an eBay listing for a Breathplay chamber. Jake got really curious and looked at the ratings, finding that a lot of people are absolutely amazed and terrified by this thing at the same time.

He got really excited the more he looked at the listing and the pictures, so he knew he just had to order it. And then, one week later, the tank finally arrived. It was roughly the size of a shower cabin and had to be shipped in a truck.

After setting it up in his garage, connecting all the water supply hoses and pumps, he took a look at the user’s manual. In it, he found that this tank offered two different ways of asphyxiation for up to two people. The first option was to let the vacuum pump suck out all of the air, and the second option was to let it get filled with water completely. The door had a special locking mechanism with a timer. Jake read in the manual that you set a desired time on the display inside and press start, after that the door gets automatically locked and won’t open until the timer is finished. Jake felt the excitement build up in his stomach upon reading this fact; There is no way for the user to open the door or stop the program until the timer has finished!

He already planned to try this out with his best friend since a lot of the ratings recommended that experiencing it with a partner and share each other’s oxygen is a lot more fun than just doing it alone.

But for now, he just wants to try this out for himself. He decided to start simple with the water option. So after ensuring everything was set up properly, he stepped inside of the completely sealed chamber, and closed the door. He then turned to the display and set the timer on 2 minutes. From all of his experience he knew that this was definitely long enough for him to make it not too easy, whilst still being quite challenging for his body to manage. After setting the time, he pressed the water droplet button to start the program. He heard how the door locked and water started flowing out of the hose at the bottom and began filling the chamber up.

This made him even more excited, and his member was already getting erect. He noticed how the timer didn’t start right away but was waiting for the chamber to get filled entirely until it would start counting down. He deemed this to make total sense because otherwise the time would already be up until he couldn’t breathe anymore.

He intently awaited the water level to rise, and after around 3 minutes, the water had finally risen to his head, signaling him he should take his last breaths now. And so he did; he intently exhaled all of his air, and slowly inhaled deeply again, repeating this a couple of times until, when the water was nearly at the ceiling, he deeply inhaled his final breath. He looked down and saw how the timer finally started. He tried to stay as calm as possible and relax all his muscles, clear his thoughts, because he knew, in comparison to his previous breath holdings, this time he had to hold it for 2 minutes, no ifs or buts.

After roughly 1 minute, his shaft was painfully hard and throbbing with need, his lack of breathing getting him really aroused. He slowly moved his right hand to his shaft and began stroking it carefully, trying really hard not to moan out his oxygen. It felt indescribable, being in this chamber completely surrounded by water, knowing that there would be no way for him to breathe even if he wanted to, the only oxygen available to him being in his lungs, and with his cock in his hand.

After 1:20, his lungs began burning like they usually did at this point, his chest slightly starting to heave up and down, enticing him to breathe again, but he knew: he couldn’t.

He thought about how it would be to stay in the tank for 2 minutes but without inhaling beforehand. He couldn’t imagine how crazy of an experience this would be.

At the 1:30 mark, his chest was now spasming more frequently and the burning became way more apparent, making him squirm a bit, but he held on.

At the 1:45 mark, his chest was violently spasming and his body was practically screaming at him to breathe. He knew that this was a bit of an overreaction of his body, and he could take a bit more, but his body still desperately tried convincing him to breathe again.

Close to 2:00 minutes he barely managed not to inhale the water, but held on, his body really relieved as the water level finally dropped again.

*****

On the next day, Jake’s friend Luke asked him if he could borrow the chamber to play with Susan. Jake gladly agreed to the idea of watching somebody else struggle in his chamber.

So Luke and Susan came over, Susan going into the tank. Thankfully, the tank had an override display on the outside, so Luke and Jake were able to set the time for Susan. Luke reassured Jake that Susan had a lot of experience so he should set it to 3:00min.

After the water level rose to the ceiling and Susan took her last breaths, the timer started counting down.

Luke and Jake smirked, seeing her completely naked form swirling there in the tank with no air but the one in her lungs.

Jake really liked her defined physique, easily noticing her defined abdominals. He also loved her beautifully big breasts that he knew were soon going to spasm.

At the 1:30 mark, her chest was finally starting to heave, begging her to breathe again, but she knew she was a long way from being able to do that again. She tried focusing as best she could, but at the 2:00 mark, her chest was violently spasming, and her lungs burned like hell. She knew from a lot of experience she could hold on for longer, but her body tried convincing her otherwise.

At the 2:30 mark her only thoughts were: “Air! Air! Oh please! I need air! Please, please, please! I can’t hold it any longer!”

Jake and Luke watched in awe as her beautiful breasts were spasming wildly whilst her face became more and more violet.

At 2:50 her body couldn’t hold it any longer and she violently exhaled, to shortly afterwards inhale the water deeply.

Luke and Jake watched in awe as her body was finally breathing water, the sight being so arousing how her mouth was wide agape and a clearly noticeable water stream was flowing in and out of her mouth.

The sight was so enticing that they just couldn’t resist to change the timer to 4:00, wanting to see more of her breathing water.

When Susan realized this, she was truly terrified, knowing that she would have to keep breathing water for an entire minute.

Jake and Luke watched as her face was now completely violet and her heart rate dropped lower every second, currently at 40 according to the display on the door.

Her thoughts were getting hazy, and she clearly felt how her desperate heart got slower and slower. The burning of her lungs was gone now, her brain apparently to asphyxiated to feel pain anymore.

And then, at 3:45, her heart finally stopped. After the tank drained at 4:00, Jake and Jake inspected her and noticed how she was definitely still dead. So they put irreversible metal plugs into her nostrils and closed her air tube with special expandable glue foam, ensuring she would never be able to breathe again. After that, they used a special magic spell to bring her back to life.

Susan was so happy to finally be out of the tank alive, but when she tried to inhale, she noticed she couldn’t, getting her face to show an insanely desperate expression.

Luke and Jake explained to her that she would never breathe again. She was very confused but had to admit liking the idea of never breathing again a lot, getting her wet with arousal, forever. Luke and Jake got an idea about this fact and decided wanting to use this. So they quickly build a milking machine which they permanently attached to her folds, ensuring that she would constantly supply her fem juices to be gathered in a big tank so that Luke and Jake could always fill a glass from the tank for their own personal consumption. This made them incredibly happy, knowing that they would never have to buy drinks again. And both of them knew how good Susan tasted, especially in her asphyxiated state.
