Hitozuma Heaven ~Takuran Ureta Shikyuu ni Kodane o Sosogu~

A successful young stock trader living a life of luxury, the protagonist now finds his greatest thrill in the married woman next door. Every trash pickup, her mature curves ignite an obsessive urge to impregnate her on behalf of her husband. Unable to resist, he carefully stalks his prey and, upon learning of her struggle to conceive a second child, forces himself on her as her 'assistant.' Behind her husband's back, this predator daily claims her ripe body. Though she resists at first, each betrayal drowns her deeper in the forbidden pleasure that loyalty never gave her. The once 'good wife, wise mother' gradually sinks into the sinful ecstasy of betraying the man she loves.
