Sister Breeder – Episode 1

Shouta has always shared a warm, protective bond with his two sisters, Rena and Aina. Having grown up side-by-side, their relationship seemed unbreakable. However, as time passed, Shouta’s affection for his youngest sister, Aina, twisted into a deviant obsession—culminating in a fateful night when he crept into her room with dark intentions.

Upon discovering her brother’s betrayal, the eldest sister, Rena, desperately intervened to shield Aina. Yet, in a cruel twist of irony, she found herself forced to bear the brunt of Shouta’s intense, misguided “affection” in her sister’s stead.

Caught between her long-suppressed feelings for Shouta and the overwhelming ecstasy of her first awakening, Rena’s purity begins to crumble. Once the model of a perfect older sister, she is slowly lured into a spiral of carnal “training” and guilt. Will she find the strength to wake from this nightmare, or will she succumb completely, becoming a tamed plaything at the hands of her own brother?
