Taking advantage of the drunk sister-in-law, the foolish younger brother-in-law acted inappropriately.
The husband went to work far away, worried about leaving his wife alone at home, so he asked his younger brother to come over to take care of her, but this turned out to be a big mistake on the husband's part for leaving another man to stay with his wife.
The movie consists of 3 main parts:
1. The sister-in-law gets drunk, and when the younger brother-in-law leads her into the bedroom, she unexpectedly pins him down thinking he is her husband.
2. In part 2, the wife is sleeping like a log with her butt up in the air, and the younger brother-in-law, seeing this, approaches, pulls down her panties, and penetrates her naturally as if she were his own bear.
3. Part 3. Similar to part 2 but with a slight difference in the sleeping position of the "sister-in-law".
P/s: It must be said that with a sister-in-law who drinks and an empty house like this, any young man would probably wish to be her younger brother-in-law.
