Matsumoto-kun, a subordinate who had just been transferred, helped Hikari's husband home after he passed out drunk at a welcome party. Encouraged by Matsumoto, who still wanted to drink, Hikari had her first drink in a long time and ended up drinking too much... Noticing Hikari's choker, the man saw through her masochistic side when she mentioned that "tighter feels better." The drunk man tied Hikari's wrists with a necktie and wrapped a belt around her neck. Completely submissive, masochistic Hikari let the man grope her massive I-cup breasts. Seeking excitement in her monotonous life with her older husband, Hikari reached multiple orgasms filled with guilt from the sadistic young man's ass spanking, French kissing, fingering, and cunnilingus! Unable to resist, Hikari sucked his raw cock and swallowed the cum he ejaculated in her mouth. With her husband away on a sudden business trip, Hikari and Matsumoto were alone in the house. Bound in the bedroom with her hands tied behind her back, Hikari was fucked deep in her throat and drowned in forbidden sex... Unable to forget the guilt toward her beloved husband and the stimulation of the hemp ropes digging into her flesh, Hikari called Matsumoto to her home and fell deeper into an irreversible affair. As proof, her choker was replaced with a real collar, and Hikari, connected by a leash, transformed into a "dog" completely dominated by the man. With a blissful expression as he greedily licked everything from her toes to her anal, Hikari fell deeper into escalating hemp rope bondage and hard sex...!!
