It's too close to call!

The girls’ screams filled the stadium. It had been a solid minute since all three champions had been fucking their final girls. Viktor, with his minotaur dick was really stretching out his girl’s hole, making it hard for him to use her tightness. Bill himself was finding it difficult to cum, since his canine cock’s knot kept getting him stuck. Firenze himself was exhausted, trying his best not to crush the girl he was fucking. Despite this, all three of them roared as they finally came into their girls. The entire crowd went silent, even stopping their fucking to see who had won. Suddenly, the girl in front of Bill screamed as her tits ballooned out along with her belly. The crowd cheered, their champion had won. Firenze pulled out of his growing girl, disappointed that it happened the split second after Bill’s. Still, at least he wasn’t last like Viktor, but he’s sure that it didn’t matter.

“That completes the first task!” Harry announced. “Bill the Werewolf of Hogwarts has won!” The crowd cheered once again, some screams from orgasms. “For winning, Bill will receive all the girls to add to his pack.” The girls in Bill’s line smiled, they all wanted another round, or four, with Bill. “Get some rest Champions, for the next task will be in one week’s time!” Harry finished his announcement and went back to fucking one of the muggle girls that just came in.

[1 Week Later]

Moaning Myrtle, a ghost killed when she looked at a basilisk, realized that she really wasn’t the only one moaning anymore. She wanted to explore, but unfortunately she was stuck where she was. She sighed, “No one ever comes here, unless they wanted to open that terrible chamber.” Suddenly, she heard the door open. She instinctively hid inside her toilet, looking over the lip only enough to see the person head for her stall. As soon as the stall door opened, Myrtle hid again.

“Ugh, at least these weird wizards have regular toilets.” The mysterious girl commented, locking the door behind her. She ran to the toilet, hoisted her skirt up, and pulled her panties down. “Aaaaahhhhh.” The girl sighed, finally relieving herself.

Myrtle got a wicked idea, once the girl finished and stood, Myrtle acted quick, and flew up into the girl’s body. The girl’s whole body shook, her mind trying to keep control of it as Myrtle possessed her. Soon, she went limp, still standing, her head hitting the stall door, keeping her up. As though she was waking from a nightmare, she shot back to awake. As the girl blinked a few times, she looked at her hands, opening and closing her fingers as though she never knew they could do that. She ran her hands up and down her body, feeling her small breasts, but perky but, her slight curves giving off just a hint of attention. “It worked!” she yelled in excitement, “why didn’t I think of possessing someone before?” Myrtle felt what was now her hair and saw that she was strawberry blonde, her hair done up in a ponytail. “Is this what muggles wear?” She looked down to her dress, a pink satin corset just above a frilly black skirt. “Must have been popular with the boys, although, probably not with these nonexistent knockers.” Myrtle said to herself. She unlocked the stall door, trying her best not to fall as she got used to walking again. As she got to the door, she took a pause. This would be the first time she would be anywhere that wasn’t a bathroom in decades. As she took a deep breath, she pushed the door open.

Myrtle adventured down the halls. All it felt so familiar, yet so different. Everything she knew before was still there, but there was a different feeling in the air. As she rounded the corner, she ran into something. She was pushed down to the ground by what felt like a wall. As she looked up from the ground, she saw that she had run into a centaur. “Oh, no.” she whispered.

“Well, aren’t you a fine muggle?” The centaur growled. As he started to close in on top of her, another voice rang out.

“Ronan! What are you doing?” Myrtle looked to see that it was Harry Potter…when did he grow such a big cock? And why did she want nothing but get filled by it? “Put her with the other muggles, we’re about to start the second task!” Harry commanded, much to Ronan’s dismay.

Ronan sneered, but grabbed Myrtle by the arm and stood her up. He pushed her to the line of other muggle girls. “Get in line, whore.”

Where were they going? What the hell was happening right now?

“Welcome to the second task!” Harry announced to the crowd, who returned with thunderous applause. “The first task measured each champion’s speed. How fast they could fill. This task is to do the opposite, to test their endurance!” The crowd cheered once more as the area was revealed. The three champions were tied up. Through magical bindings they floated in midair, unable to move or do anything. “The champions have been magically bound for the participants safety. The goal of this task is to be the final one to ejaculate. The trick is that we have promised three girls freedom if they can be the first one to make a champion orgasm.” The crowd cheered once more, “Let’s bring them out!” With that, the three girls entered the arena.

The bright sun hit Myrtle right into her mortal eyes. She had not seen the sun in decades. She felt the warmth of it, really taking it in. What brought her back was a minotaur roar and she remembered where she was. She looked around at the crowd, some simply spectating while others were participating in carnal acts of pleasure. At that moment, the booming voice of Harry Potter rang through once again.

“Ladies, welcome. Your goal for today is to make your beast man cum as fast as you can.” Myrtle’s eyes went wide, he couldn’t be serious. “Now, we know you don’t possess any magic, so I had my potions mistress conjure up some potions for you to use. You may find them in the chest behind you.” The girls took note of the chest and nodded. “Now…begin!”

With that, the task began. It seemed that Myrtle was assigned to the minotaur. She hesitantly walked up to the monster. His flared cock, even flaccid, reached down to his knee. She gingerly touched it, once she did, it started to grow. Her eyes went wide, having been decades since she’d seen a cock, nevertheless one this big. She started to lick it, if she could, she was going to win and be free in this new body. She circled the tip with her tongue. She started to take it into her mouth. Using both of her hands, she stroked it. As much as she tried, she just couldn’t get it right. She ran to the chest and opened it. Before her were a plethora of potions. One that caught her eye was a white one. She examined it, it looked almost like milk. Myrtle shrugged as she popped the cork and downed the entire bottle. She took a few breaths, the potion was sweet, like cream. She groaned as she dropped the bottle to the ground. She could feel an immense pressure building in her chest. She looked down to see her breasts billowing out. For the first time in her life, and the girl’s body’s life, she had cleavage. She watched as the valley of cleavage grew and grew, causing her pink top to tighten. The pressure was becoming too much as her tits reached J cup proportions. As soon as she was about to say she was surprised the top was holding, the buttons all bursted. She lifted one of her enormous tits now, this will do.

She walked over to the minotaur again, now with her new assets. Thankfully, the cock was still erect as she sandwiched it between her own monster tits. Squeezing them together, she gave the minotaur, what she hoped, was the tit fuck of his life. Myrtle herself came, the sensations of having her tits fucked was too much. She looked to either side of her, it looked like the girl with the werewolf also found a potion in the chest, but instead of her breasts, it was her ass that grew.

To the other side, she could see the other girl with the centaur holding on for dear life as it seemed the centaur had his entire dick in her as she held onto his horse half, releasing his cum inside her.

“And with that, Firenze is our first loser!” Harry announced. The girl finally let go and fell to the ground, her belly full of Firenze’s seed. ‘What did he mean by loser?’ Myrtle thought.

As Myrtle looked back, she could feel the minotaur’s cock growing hotter. If anything, she could be second.
