The window opens to the Kanda River, and in this shabby four-and-a-half-tatami-mat apartment, the married woman learns pleasure... and love. A middle-aged teacher summons the mother of one of his troubled students and approaches her voluptuous body. He forces a deep kiss on her, and perhaps excited by this, he grabs her erect nipples. Her masochistic nature emerges, and her pussy becomes soaking wet, and her love juices drip even more with cunnilingus and fingering. He shows off his rock-hard cock and deep-throats her, drooling. He can't help but cum when he sees how skillfully he uses his tongue! The middle-aged teacher finds the perfect toy, and continues to restrain the married woman and relentlessly torture her with a vibrator and a rotor. The married woman, completely consumed by the man's mischief, no longer resists and continues to accept the torture, and in the end, she welcomes his erect cock into her hot, wet vagina many times.
