A widow living alone in her small, run-down apartment by the Kanda River finds pleasure...and love. When a teacher discovers a secret about his student's mother, he invites her over under the pretense of keeping it private. Unable to resist his advances, she succumbs to his desires, allowing him to kiss her passionately and caress her breasts until they are both aroused. He then pushes his throbbing member deep into her throat, filling her mouth with his essence as she eagerly swallows every drop. As he continues to tease and torment her sensitive body, she becomes increasingly submissive and responsive. Finally, she mounts him, taking his thick, hard shaft all the way inside her tight passage. They lose themselves in their passionate union, with neither able to control their lustful urges any longer. Note that recording contents may vary depending on distribution method.
