A woman with a plain work and life meets her school teacher on an app...! When he sees her masochistic desires and her sexy, voluptuous body that she can't hide, he says, "You have no experience, right? I'll teach you about men!" She can't refuse and begins her masochistic training! "You have to drink every last drop of my sperm!" She is repeatedly exposed and humiliated in every place! "You're so excited you might get found out, your pussy is dripping wet, right?" The more she is insulted, the more she cums and apologizes! Sorry for being a perverted sow...
