[Takasugi Kou] Mama ga Ippai (1) 4-nin no Mama ga Yattekita! [DarklordMTLs]

Akio's world tilts when his father Torao introduces four stunning, busty women as his mistresses and potential legal wives—all moving into the household at once. The imperious Tomoko keeps order with a riding crop and rope, and when Akio peeks through the door at Akane's bound, blushing punishment, she beckons him inside to watch. With a harem of mature beauties all vying for position under one roof, every corridor holds a new lesson in what this strange family really means.
