Shrink helps us understand that siblings can be attracted to each other

In this explicit video, a young man and woman are seen visiting a doctor for some unspecified issue. The doctor, a middle-aged man with a deep voice and a reassuring demeanor, begins to ask the couple some questions about their relationship. The couple, both in their early twenties, seem uncomfortable and nervous as they answer the doctor's questions. The doctor then asks the couple to undress and lie down on the examination table. The man and woman obediently comply, and the doctor begins to examine them. As he does so, he notices that the man's penis is erect, and he asks the man to show it to him. The man hesitantly does so, and the doctor takes it into his hand, admiring its size and girth. The doctor then asks the man to show him his ass, and the man complies. The doctor then asks the man to spread his cheeks, and he does so, revealing his tight asshole. The doctor then asks the man to take out his cock and stroke it, and he does so, moaning in pleasure as he does so. The doctor then asks the man to show his cock to the woman, who is lying on the table with her legs spread, and he does so.
