Driven by a twisted obsession, Rin Azuma, a married woman fixated on conceiving, targets men with the same blood type as her husband—type A—believing that as long as the blood type matches, any child she bears won't raise suspicion. Her mind increasingly warped by this delusion, she aggressively seeks out men, mounting them in the cowgirl position and forcing them deep inside her, demanding creampie after creampie. Each encounter plunges her further into depravity, as one after another, the men succumb to her insatiable lust, experiencing intense, penetrating pleasure they've never known. Amid this twisted romance, hidden desires stir beneath the surface, unseen by the world.
