SPRD-1153 Mio Morishita's trip with her son turns into blackmail and group sex

Mio Morishita decides to go on a trip with her beloved son for the first time since they became lovers, and the two of them are excited to make love without hesitation. When they reach the inn, they head to the hot springs and confirm their love in the family bath, but a man watches them, takes sneaky photos, and later corners Mio alone. Shown the pictures, she panics and gives him a mouthful service as told, and that night she cannot enjoy the meal or her son's love because of the threat. The next day, the man makes her masturbate in front of his subordinates, and then two of them use her, culminating her over and over until cloudy liquid is poured on her.
