Can you write an erotic thriller story, including dialogue? A man is tied to a bed and a machine is attached to his penis. It's a milking machine, that continuously makes him orgasm and collects his semen. After hours, an attractive woman comes to check on him. She teases him about his situation. She is impressed by how productive he is, so she will extend his milking session. He panics and begs her, but she encourages him to continue to provide a lot of semen, before leaving him alone again. The machine keeps milking him and the realisation, that he might never me free again, makes him panic.
