[Breath Control × bitchsuit caress] The more Nureba feels it, the more oxygen-deprived Nureba becomes, triggering Nureba puppy-like instinct to serve.

My consciousness was beginning to fade away.

Inside the stuffed animal.

My body was completely curled up, bound by two layers of latex and urethane.

I breathed through a small gap in the protrusion that was clamped over my mouth.

Through the zipper...

Other than that, no oxygen could reach me.

But—even so, the depths of Nureba body were hot.

Behind the mask, her throat involuntarily made sounds in sync with Nureba shallow breaths.

At that moment, Nureba felt something hard and small inside her body.

In that instant, a warm, soft vibration reached the depths of the latex.

"Hh… ah… mmm… hhf…!"

There was no vision. No sound could be heard.

But I could feel something “reacting” inside my body.

Deep inside. The stimulation being given through the rubber grew hotter and hotter.

I squeezed it myself, gave it to myself.

If I didn't move more, I would want more oxygen.

If I kept moving, I felt like I could breathe deeply—

"Nn-aah… hhf… khh… nn… ahh…!"

I can no longer distinguish between breathing and caressing.

With the protrusion in my mouth, I shake my throat and force out my breath.

I shake my legs and press down with my toes.

Even though no one is touching me, a heat that feels like it’s bouncing back repeatedly deep inside my body.

(…Ugh… Uh, ugh… No, this is bad… Ugh)

And then—the limit arrives.

The breath she exhaled doesn't come back.

Even the gaps between the protrusions grow heavy, as if refusing to breathe.

Along with the pleasure, the fear of suffocation overwhelms her.

"Hh… fuu… nnh… I… I can’t… anymore…!"

She desperately makes her throat vibrate.

No sound comes out. No expression.

But the instinct to “communicate” caused the raspy air to rage inside the mask.

It's painful. The limit.

If this continues, oxygen won't reach me.

Trapped, my legs twitch.

My trembling toes stop moving.

But even so, my mouth remained clamped onto the protrusion, trying to breathe shallowly and briefly.

(…Help me… but…)

Beyond the pleasure, the thirst for oxygen and the unbearable longing overlapped.
