Congratulations! The 50th series! ! Mother's Friend Hiroka Suzuno

Congratulations! The 50th series! Yuzuru's mother's friend, Hiroka, came to stay and remembered the sexual awakening she once felt with her, and felt a secret excitement. That night, Hiroka gets completely drunk while talking about memories. Yuzuru, who has grown up splendidly, feels a pain in his crotch and unbearably sets up a night in his room. Even after that, the two of them enjoy a sweet relationship while stealing their mother's eyes. However, Hiroka feels guilty about continuing an unfaithful relationship with her friend's son...
