Round 492

The walls' breathing stopped completely—everything except for that low pulsing hum growing stronger like a heartbeat counting down seconds until the next phase began. Tendrils of living rock slithered across the floor, coiling around both their ankles in an unbreakable grip. One particularly thick appendage snaked up higher along Halie's calf, pausing just below her knee before continuing its slow ascent toward more vulnerable skin.

The walls themselves seemed to shift minutely, the stone grains reorienting as if preparing for something new. The pulsing light intensified further, bathing them both in a brilliant, almost painful glow that made every vein visible beneath Silra's skin. The fluid between them surged again, responding to her whispered demand with renewed energy.

"Take me," she repeated, her voice huskier this time as the bioluminescence cast stark shadows across her face. Halie could feel her own pants sliding down her hips under the stone's insistent touch, baring more skin to the hungry air and whatever waited in these walls.

The concrete beneath them vibrated with a low rumble that seemed to resonate through their very bones. The temperature continued its steady climb, making the air feel thick and heavy against their skin.
