Harry is fucked and to cum inside Hermione

Harry grunted as the cock penetrated his pucker and reamed his asshole. He felt the cock inside him as it turned itself around and was poking his prostate. A jarring sensation jolted Harry awake as his prostate was being massaged by the black cock. He was losing his grip on his orgasm; he was going to cum and hard. He closed his eyes and fought back with all his might. The machine sensed that he was holding back and a small pin popped out from the end of the cock and pierced his prostate. Harry scream in pain as the thin metal pin implanted itself in his prostate. Harry heard a popping and clicking sound. Something electrical was starting up and Harry was very afraid. Harry's body suddenly shook as an electrical charge was passed through the rubber cock into his body. He couldn't hold it in anymore. "S-s-s-sorry Hermione!" Harry puffed as the orgasm took over his body. Harry's cock exploded into Hermione's pussy. He came and came until he was shooting dry.

The orgasms were increasingly painful as he had nothing to expel from his testicles as they were completely empty. The pin retracted and the rubber cock was pulled from his asshole. Harry felt like he was taking a big dump as the large rubber cock slowly left his ass. His flaccid penis had been milked completely of it's cum and it drooped onto the rubber harness.
