[Muru no Honbako] Sacrificial Mother-Son Mating ーThe Mother and Son Who Became the Village’s Sacrifice Mate Eternally in the Depths of the Darknessー [NTerm]

An anguished mother, her long black hair framing a trembling face, is forced to become the village’s sacrificial mate, her massive breasts leaking milk as her son, Kisuke, presses his eager penis against her swollen womb. The black‑and‑white panels reveal her desperate cries—"It was you, Mom!!"—while his youthful body, marked by a fierce, animalistic urge, overwhelms her with rough, relentless thrusts that echo through her belly. As she clutches a hidden book bearing her own name, the dark shadows of the village close in, promising an endless, painful union that will forever bind them in the abyss.
