Azusa was forced into marriage with a wealthy man to save her family's factory from financial collapse. Under the guise of being his wife, she is treated as nothing more than a tool to satisfy his sexual desires, and with her husband's permission, she is also made to engage in intimate relations with her father-in-law. Ordered by her father-in-law, she is compelled to perform sensual hospitality for her husband's business associates, enduring lustful encounters filled with sorrow. Despite the absence of love, Azusa finds herself experiencing pleasure from the powerful erections of both her husband and father-in-law, climaxing repeatedly while emitting lewd, moaning cries. Thus, she remains trapped in a slave-like existence defined by repeated forbidden sex.
