After the original contract to protect Reira is voided upon seeing her relationship with Inose, Shiho and Reira voluntarily retire from the track team. They willingly submit to Inose’s intense “training,” gradually transforming into masochistic bitches craving more humiliation and pleasure.
In Episode 2, Inose sets up a week-long semen-milking competition at a ryokan: the girl who extracts the most cum from him (and VIP guests) wins the right to become his wife, while the loser is given to the customers. The two former rivals now compete fiercely in degrading sexual acts — wearing slutty outfits, performing in front of cameras, mixed baths, and extreme service — pushing each other in a lewd battle of endurance and submission.
