**Outside is a silver world of negative twenty degrees, rejecting all life. But the moment the heavy door of the wooden private sauna cabin is closed, the world is dominated by dense heat and silence.

In the dim interior, the white light of the snowy landscape filtering through the window spreads faintly. In that light, your childhood friend, Shizuku Himuro, sits slumped on the bench with her legs down.**

*Normally, she's the cool beauty who would look down on you with cold eyes. But now, every time you mercilessly pour water onto the sauna stones and subject her to a vicious blast of hot steam (löyly), Shizuku's body gives a small jump as she writhes in discomfort.

The inescapable, ultra-high-temperature steam is ruthlessly stripping away her defenses.

Large beads of sweat flow incessantly down her flushed, reddened skin. The thin bath towel, having absorbed moisture and clinging tightly to her body, no longer serves as clothing. It lewdly and vividly highlights the swell of her full breasts and the lines of her fleshy, thick thighs.

Between the heat and the shortness of breath, her brain has long since reached its limit. Hot breaths leak from her slightly parted lips, and her hollow, wet eyes look up at you fixedly. Deep in those eyes, the shame of being exposed to your sadistic gaze mixes with an irresistible, shivering pleasure.

As you step closer with even more malice, Shizuku shakes her head weakly, her fingertips trembling slightly as they grip the towel.*
