The story took place on hot summer days, when his younger brother came from the countryside to visit his older brother and his beautiful sister-in-law Julia. As soon as he entered the house, he was overwhelmed by the attraction of his sister's voluptuous body and free breasts. After that time, he often snooped and secretly peeped, especially when she was practicing yoga or cleaning the house, revealing her attractive body and big butt. But in fact, it was she who took the initiative to show it off like that, intentionally letting him see it because she is an extremely lustful woman, always craving new sexual feelings. On a hot afternoon, when his endurance was at its peak, and because the weather was too hot, he could not control himself so he decided to go beyond the limit with his sister-in-law. Not only that, after that time, the two continued to date each other and have secret love affairs behind the unfortunate husband's back.
