This is a record of the incestuous days between a son-loving mother with large breasts, who accepts her role in handling her son's sexual needs despite knowing it's wrong, and a hikkikomori son who has shut himself in his room ever since failing his university entrance exams. Ever since his failure, the son refuses to leave his room when his father is home. At some point, his emotional support became solely his mother's breasts. Facing a mother who accepts everything, the son's desires escalate...! Even accepting her son's semen with her own vagina, here is born the ultimate maternal love AV.
