HZGD-153 The shame-drenched sister-in-law ★ Tsukasa Nagano trained as a human wife by a perverted D/M pet

My older brother who decided to live in his younger brother's couple's house on a single assignment. One day, he accidentally finds out that his younger brother's wife is having an affair. My older brother, who has been fascinated by his younger brother's wife's erotic body and perverted habits, plays with his young and fresh limbs on the condition that he does not tell the fact of his affair. Married women are addicted to pleasures and perverted play that they have never tasted before, and their bodies and minds fall.
