A riding lesson

At first, Harry thought that he did not change rooms after all. He still has the exact same room around him. His finger was outstretched, but where Hermione's ass had been a moment ago, there was now empty air.

Instead of Hermione, he was now on the run with Parvati. Harry remembered her transformation now. She looked rather elegant, in a way. Long, smooth riding boots, an elegant, if low cut, jacket, and a black helmet on her head. She looked like she was about to participate in a high class riding tournament. Except for the fact that she did not wear any pants.

Her caramel-colored ass was wie a sight, Harry had never really realized that before. "Hi Parvati." He greeted her in a friendly way. "Oh. Hi Harry." She looked at his outstretched finger and grinned a bit, but did not say anything.

"The jockey, that was the name of your costume, right? Well, correct me if I an wrong but, dies that mean you want to do some riding?" Harry already pictured her fine brown ass going up and down on his lap.

"Precisely." Parvati said with a hungry smile and took a step towards him. "And I certainly hope that you will show more endurance than that Ravenclaw guy." Wow, Harry thought. She did sound so eager to ride dick, why did he never notice that about her earlier?

Grinning, Harry sat laid down on the bed, parting his robes to reveal his cock, still hard from his conversation with Hermione. "Hmmm, you already have a much better...saddle" said Parvati and nimbly swung a leg over him. His cock disappeared inside of her in no time. The squelching sound of his hard dick entering her wet pussy intermingled with a long sighing moan.

Parvati smiled down at him, the smile of someone who knows that the next few minutes would be a great time. She placed her warm hands on his naked chest "Here we go then" she almost whispered in a mesmerizing seductive time he had never heard her use before.

Her hips started to move. It were small movements at first, barely visible from the outside but oh boy did Harry feel them! I'm tiny little circles, her ass gyrated on top of him. She kept him deep inside of her all the time. Parvati's moans sounded melodious, her eyes were closed, her face was split into a wide smile. She was completely in her element.

After a bit, she picked up the place. Her moves got faster. Faster and wider, her ass was dancing up and down more than circling him now. But somehow, every now and then she changed it up, just when he thought he had figured her out. Harry found himself groaning happily, he enjoyed every second of this.

She rode him to the edge, just to slow down again, giving him the chance to recover just enough to withstand the next onslaught of her skillful hips.

Parvati's moans were faster now, louder and more intense. Harry had the feeling that she started to cum, her insides clenched on him as she let out a long groan. He was close himself now. Just a few more seconds and...

But then, he felt it again. The darkness took him. It took him on to the next room. It rather the same room? Who knew, but it certainly made Parvati disappear.
