Riona, a young wife who spends her peaceful days running a long-awaited cafe with her husband. Upon attending a class reunion, she reunites with the man who was once her master, the one who trained and developed all her erogenous zones. Although she thought she had nothing left to gain since she was already married, her instincts as a female slave begin to ache as soon as he is near. Right beside her classmates, she is suddenly subjected to face-fucking and anal retraining. Her asshole, which was barely touched during her usual lukewarm sex, is stretched wide open, and unable to resist, she engages in hard anal sex at a hotel. Ignoring messages from her husband, she happily accepts double-hole creampies, skewering face-fucking, and spanking, reaching climax after climax. Reminded time and again that she is nothing more than a meat toilet, she completely falls into a state of broken, blissful orgasm.
