Mama's Classmate The Promise Of A Green Spring

One evening, a young man returning home met Yuriko, his mother's old friend. He exchanged greetings while seeing his mother Ai and Yuriko nostalgically flipping through a photo album. Then the young man felt a strange gaze—it was coming from Yuriko, his mother's friend. And Yuriko's son also felt something was off. He was flustered the whole time by the meaningful glances from Ai, his mother's friend. Eventually, this turned into a dense incestuous affair in the bathroom and bedroom, where Yuriko and Ai entangled with each other's sons.
