This time, the one being trained is K-cup busty 'Yuzuki Marina'. She was an extreme masochist. Unable to contain her pent-up masochistic desires, she volunteers to become a slave to the director who is filming the training! In front of general audience, she indulges in bondage, gets on all fours to lick assholes, and even performs sex. The training continues afterward, increasing in intensity, but her masochistic body feels pleasure and keeps orgasming until satisfaction!
