Mother gang raped in front of her son's eyes

Reiko's mother is worried about her only son Atsushi, who has been feeling unwell recently and has been asking for money more than ever for buying teaching materials. A male student suddenly appears before Reiko, worried that she is being blackmailed by bullies at school. "I asked for money to go to an image club, but Atsushi broke his promise. So I was thinking of having my old lady play with an image club..." she forcefully pushed Reiko down.
