The brother, who had to go on a business trip by company order, decided to stay at his younger brother's house for several days. The brother was astonished by the beauty of his sister-in-law, whom he hadn't seen in a long time. Knowing his sister-in-law's loneliness, the brother took advantage of his younger brother's absence and relentlessly pursued her, licking her vagina vigorously. Midway, his younger brother returned home, interrupting them, but he seized another opportunity to perform cunnilingus. His sister-in-law, who had been resisting, lost her rationality and unable to suppress her urges, engaged in intercourse with her brother-in-law, transforming into a lustful beast and exploding with sexual desire.
