Extremely authentic incestuous erotic painting: Parent-Teacher Association President's mother being rubbed by her son - Kokusei Aya SPRD-782

For this outwardly virtuous mother, there was a forbidden secret she absolutely couldn't let the neighbors know. Living a single-parent life with her son, who was going through puberty, her son, though not explicitly saying so, seemed quite interested in her full breasts lately. He was also enthusiastic about sex and had started frequently rubbing them. "I know you're a good boy... but could you please stop rubbing them..." The son completely ignored his mother's kind pleas and continued to rub and knead them!
