AVSA-090 Kohinata Mai: Please Train Me to Be a Good Wife – Humiliation Training Edition

A husband forces his wife to undergo humiliating training with another man's penis inserted into her tight hole. Before the husband watches, she is tightly bound and stripped of mobility, left completely helpless as she's penetrated roughly in a degrading act. The husband gets aroused watching his wife suffer, while she helplessly drips arousal seeing her husband's excitement. Eventually, the husband joins in, participating with another man's penis as they make the wife climax repeatedly, while the husband is anally and sexually assaulted. This is the ultimate depiction of a cuckold marriage.
