why he wanted to pull out her underwe@r ?

This is the part of a movie ?This clip of the movie makes confusion to the viewers till the last movement.In the starting the women refuse to do so but the continuous disturbing of the young boy ( seems he is not the son ) makes her to leave the boy to do so.Although the clip is in the unknown language the movement of the movie members had made some how easy to know what they are telling in the video.

Just check out this full video and guess why the small boy tries to pull down the cloth? Share your answer in the comment box.
