The film has 3 parts with different beautiful actresses but the same content. The story tells about the husband who had just returned home from outside, saw his sister-in-law crouching with only her round buttocks exposed, she thought it was her wife, so she took a cock and rushed in from behind to make a shot to relieve her trouble, the surprised sister-in-law could only moan happily. After fucking for a while, the perverted husband realized that it was his sister-in-law, but he had missed it, so he decided to fuck until the dock, as for the sister-in-law, she hadn't fucked anyone for a long time, so she was willing to continue this clumsy rain.
