Michiko is a mature, amateur private tutor who, from early afternoon, secretly engages in lewd acts with Junpei, a naive virgin, behind her husband's back. She gently embraces him, openly revealing everything as she guides him toward penetration. "You've done so well... today's reward is me masturbating for you. Watch me closely..." she murmurs in a warm, sweet voice. Responding to her words, she offers her entire being to the pure and innocent Junpei. Her passion and tenderness deepen the bond between them.
