New OC challenge? final part (Patreon)

After a few seconds with the vibrator at maximum power, she could no longer contain the urge to touch herself or hold her breath. Patreon-chan: "Don't you think you should lower the vibrator's intensity?" Jennifer: "No way, it's more fun like this. Besides, I might be able to hold out for four minutes if I don’t give in, haha." She covered her mouth with her hand, trying to hold onto the air left in her lungs while trembling and rubbing her legs together tightly. She had already coughed out air, causing her contractions to make her stomach suck in as much as possible, expanding her ribs to the maximum, which also made her breasts bounce despite the tight swimsuit she was wearing.By the three-minute mark, it was too much, and the vibrator’s intensity didn’t let up. In her final seconds of consciousness, she felt an uncontrollable urge to touch her breasts and groin, triggered by the lack of oxygen, which also aroused her. At the same time, she desperately wanted to swim to the surface and breathe. But finally, as she looked up toward the surface, her body gave in. She released the little air left in her lungs and began to sink slowly to the bottom of the tank while her body convulsed rhythmically. Her torso moved forward and back, sucking in water and trying to expel it, over and over for several seconds.Jennifer and Patreon-chan were murmuring outside the tank while her body, face down at the bottom, continued to convulse rhythmically. The movements slowly began to stop just after the four-minute mark. At that moment, the only sound was the faint vibrations in the water from the vibrator, still at its maximum level.After Jennifer and Patreon-chan left, her body remained at the bottom of the pool. About five minutes had passed since she submerged. Fortunately, a tank maintenance worker forgot her bag and noticed someone in the tank. She quickly rushed to rescue her. The worker had knowledge of resuscitation machines and was able to revive her in time.
