HAVD-566 - Young wife Miharu is her father-in-law's plaything

Back when she was a student, Miharu gave her virginity to Ginji, who would later become her father-in-law. Eventually, she entered a loveless marriage with his son, becoming part of the family, yet she continues to engage in illicit affairs with Ginji. Miharu longs for Ginji's love, but day after day, she is treated as nothing more than his sex toy. When Miharu's biological father, from whom she was separated in childhood, reappears, Ginji orders her to commit incest with him. Despite being forced into such acts, she continues to adore Ginji, calling him 'Father' and 'Father-in-law.' She is such a lovely daughter-in-law. The highlight is the scene where she meets her biological father while completely naked and bound in rope! In the climax, she and Ginji unite in body and soul, but... it's not reality! It feels a bit cartoonish, but I suppose that works too? Is this typical of Hibino's work? I feel comforted by Miharu's body and her 'devoted love,' but Ginji's son, who was used as a mere pawn, is truly pathetic—worse than a clown.
