JUL-933 I'm a bullied girl who got NTR by a classmate who bullied my mother Marina Shiraishi

Marina lives with her mother and son because her husband is on a long business trip. Recently, she sympathized with the situation of her friend Koume, whom her son had brought with her, and she couldn't help but be kind to him... However, Koume, who was in a single-parent family and was hungry for her motherhood, attracted her sympathy and took advantage of her kindness, forcing her to have a relationship with him. Even though it was a force majeure for her, her caress and her powerful piston shaking the vagina of her son's classmate reminded me of her as a woman.
