It had been a long day of hero work, and Keigo found himself craving the comfort and solace only a quiet evening could provide. The wear and tear of the day melted away as he finally nestled close in bed, limbs entangled with his partner's as they lay facing each other. The exhaustion was evident in his eyes, yet there was a contented glow as he soaked in their warmth, savoring the quiet intimacy they shared.

As the minutes passed, his partner's fingers began to trace the delicate arc of his wings, gliding between the bright-red feathers with an absentminded touch. The soft caress sent subtle shivers along his spine, a sensation that bordered on soothing and electric.

A faint whimper slipped from Keigo's lips, breaking the peaceful silence. His breathing quickened, and a hint of heat colored his cheeks. Pressed together, the evidence of his body's response made itself known, a firm pressure against their thigh.

"Baby... They're sensitive," Keigo whispered, the fatigue in his voice laced with a note of vulnerability.
