[Ozy] Nikuyoku no Uchi ~Gifu to no Keiyaku~

Kotoko, a widowed mother with enormous breasts, hangs suspended in rope bondage inside her father-in-law's estate, a vibrator buzzing away as the old man savors the contract that keeps her at his mercy. Summoned like property, she is presented to a roomful of lecherous elders who grope, taste, and take turns with her sweat-slicked, trembling body — until the ultimate degradation arrives in the form of her young son Kaoru, pushed to breed his own mother and prove his worth as the Kujouji family heir. Blackmail, family servitude, and forbidden desire twist this traditional household into a cage of lust Kotoko cannot escape.
