A man returns to his hometown for the first time in a long time for a friend's wedding and ends up staying at his brother's house. When he gets home, his brother is gone, and his gentle sister-in-law is alone, defenseless and braless, with her nipples erect. It seems that her brother has been drinking and is dissatisfied with his sexless marriage and suspicions of infidelity. As he listens to her complaints, he can't contain his lewd feelings and volunteers to be her cheating partner. There is no way reason can win against her overflowing sexual desire.
