A younger brother lives with his older brother and his wife. Curious about his busty wife, he secretly films their life with a video camera. One day, his brother's wife comes to him for advice, saying she's worried about her brother cheating on her while she's away on a business trip. As they drink and talk, the younger brother becomes aroused and approaches his drunken wife. At first, the sister-in-law refuses, but her brother-in-law's caresses her and she ends up violating him. The wife, captivated by her brother-in-law's youth and big dick, takes a bath with him, masturbates with him, and the next morning, they film each other and cum over and over again, even allowing him to cum inside her.
