A Classroom

This particular classroom, was in a hallway nobody used. Not even Filch came this way, so Harry often came here when he needed some alone time.

With a quick Alohomora, he was in the room and able to take a seat at one of the desks. There, he sat back and let his mind wander. He hoped it would allow him to get Ginny out of his head, but it didn't. Instead, Ginny dominated his mind. Images of her, posing in outfits that would give her brothers heart attacks. Harry was starting to regret sneaking a peak at one of Dudley's adult magazines during the summer, as they were all turning into fuel to help him imagine a girl he shouldn't be fantasising about.

His cock was getting harder in his pants and he was starting to regret not going to a bathroom. He really needed to relieve the pressure.

Seeing no other option, Harry got up off the desk and undid his pants. Taking his cock out, he starts jerking himself off whilst imagining Ginny was the one doing it. All the while, she was dressed in sexy outfits. A skimpier version of her school uniform, a red bra and panties, even stuff like french maid and sexy nurse outfits.

His breath began to hitch, as he let out moan after moan. He didn't know why he was suddenly attracted to Ginny, but he knew she would likely be invading his fantasies for a long time. And as he imagined her sucking on his cock, he let out a roar as he started shooting his load into the air.

However, as he came all over the floor and desk, the classroom door opened and someone stepped inside.
