Manhood

A man named Tommy is preparing for a standard medical procedure. Despite some nerves, the nurse reassures him that everything will go smoothly. But just as the surgery is about to begin, the nurse and the doctor start behaving oddly.
After the operation, Tommy wakes up alone and senses something is amiss. He uncovers his bandages to discover his manhood has vanished. In a panic, he finds a message instructing him to go to the cellar.
In the basement, Tommy encounters a monstrous transformation in the surgeon. She is engaged in a sexual act with the nurse, using Tommy's missing member. Desperate to retrieve his manhood, Tommy strikes a deal with the creature, agreeing to part with his soul and more to satisfy her desire for a human-demon blend.
His appendage is restored, but he must now engage in a threesome with the monster and the nurse to fulfill the unsettling pact they've made.
