Derrick shuddered, something in his mind screaming a warning, but he was too overcome by the throbbing sexual need to do more than stare helplessly as the woman undid her towel. It fell away, and the young man gasped to see a mass of writhing green snakes instead of hair on her head! It was almost enough to break through the orgasmic fog clouding his mind, but then he realized he could not move his legs. They were rigid, the paralysis sweeping up his body.
The woman grinned and stepped forward, sliding onto his throbbing erection just as it literally went rock hard. Derrick finally remembered what a Medusa was and what looking at one did. Yet even though he was becoming solid marble, the erotic sensations amplified. There was no pain, only intense pleasure as the woman rocked back and forth on his unmoving shaft. The climax built quickly, and his last breath came out as a moan of pleasure just before his chest hardened. The woman cried out in her own pleasure, and Derrick's final movement was throwing his head back, eyes wide as the intense orgasm obliterated all other thoughts.
The Medusa continued to ride the thick marble cock for a few minutes, drawing out her own pleasure. When she finally slid off, she grinned at the glossy marble face. The boy had his head thrown back, eyes wide and face showing amazed pleasure. She had made some changes to him, adding a few years and some muscle, plus changing his hair, and of course, vastly improving his equipment. The resulting statue showed a handsome young man with curly hair, strong features, an athletic build, and arms out in a welcoming gesture. Not only had he made a far better sculpture, but no one would recognize him.
"Enjoy your new... well, I suppose it can't be called life. New existence." She leaned up and kissed the statue's cheek as her hand slid around its cock. "I am sure you will bring quite a good price. Not that you would care about that, or anything else." She slipped her hand in a pocket and drew out a phone, which she used to photograph the new erotic statue. She'd have to update her web site and get these new pieces cleared out to make room for the next victims. Putting her phone away, she hummed to herself as she wrapped the snakes back up and sauntered out of the garden.
Despite being solid marble, the statue that had been Derrick was still frozen in the moment of his final orgasm. There was no sense of self, no awareness of anything but the overwhelming pleasure that blotted out all other sensations, the most intense moment of his short life stretched out for eternity.
