The single mom, who was blackmailed with the weakness of illegal work, is made to do excessive services that she wouldn't normally do, her well-fleshed body as a married woman is touched as much as he likes, and even oral sex and semen drinking. Furthermore, the man's demands become more extreme, and she ends up allowing sex and even creampie. However, the single mom, who begins to feel loneliness that she can't confide in anyone and joy at being held, eventually becomes dependent on the man and begins to seek him out herself...
