"Akari Niimura" dominates her bound M-man, making him submit and serve her every need. She teases him mercilessly with her hands and feet, pushing his buttons until he's at full erection. When he tries to resist, she takes control by forcing him to perform oral sex on her while sitting on his face. His cock becomes fully hard under her weight as she rides it like an animal. The situation escalates when Akari discovers his unexpected size, leading to a power struggle where they both lose control of their desires. In the end, Akari shows no mercy in satisfying herself before using him for her own pleasure - including anal play and urination. Despite being treated like a toy, the man can't help but enjoy himself under Akari's skilled guidance.
