Tonks froze the moment Hermione spoke. Even without looking at her, Tonks knew she didn't mistake her voice.

Though, it certainly felt different coming from the outside. Tonks wanted to disappear, to melt away. But that was not possible, so she decided to do the next best thing and transform. She tried that, … only to realize her body was not responding.

"A nice spell I discovered while reading," Hermione spoke once more, her footsteps getting closer. "It's developed uniquely to prevent metamorphmaguses from transforming."

"No, there's no such spell like that," Tonks gasped. Maybe it was not the best target for her little argument, but she was not exactly in a state that allowed her to focus. She tried to focus, oh, she tried … but it was hard. Very hard.

"I wouldn't argue against it," Harry answered. "No one knows better than our little genius."

Tonks opened her mouth to argue, then something clicked and she looked at Harry. "Y-you knew!" she gasped. Though, her voice didn't come as strong as authoritative as she wished. A part of it was she was unfamiliar with her voice … but the bigger part of it was the fact that Harry was still inside her, still moving. There was only one change, his reckless railing turning into soft, long brushes.

It was what allowed her to speak at all.

"Of course, I knew," Harry answered.

"How?" Tonks gasped.

Harry laughed, and Hermione joined it. Tonks ignored the second set, doing her best to focus on only one side of it. "Well, there's your hair," Harry said, forcing Tonks to look at her bright pink locks, but in Hermione's bushy-haired style that wasn't fully tamed even under the constant blast of hot water. "Also, you're not exactly a good actress."

"B-but, you didn't say anything," Tonks followed, trying to sound angry. It didn't come as intended.

"Why would I," Harry laughed. "You have an open invitation to join us, after all. And it was fun watching you trying to act clever."

Tonks didn't answer. She was the one that started, after all. She decided to stay silent. Unfortunately, her determination was quick to destroy when Hermione grabbed her hair and started dragging her.

Tonks barely managed to get her onto her feet, helplessly following Hermione. The rough pull left no chance. "Hey, what are you doing!" Tonks cried, feeling even more ashamed of her reaction. She was supposed to be a strong auror … not whatever this was.

"Dragging you to somewhere with a bit more room, of course," Hermione answered.

"W-why?" Tonks said, this time interrupted by a sharp breath as she was pushed onto the floor. For once, she found herself glad for the pointless ornery furnishing, as the carpet was thick enough to absorb the hit, making it more unpleasant than painful.

"To extract the payment, of course," Hermione answered, and started shedding her clothes aggressively.

"Payment for what?"

"For using my looks without permission, of course," Hermione mocked her. Tonks trembled, feeling confused at the sudden rush of feeling as Harry joined them with a towel in hand, drying his hair as he watched with a huge smile.

"A-are you going to just watch?" Tonks asked Harry.

"Why not, it's fun. Look," he answered as he waved his hand, and the wall turned into a mirror. Tonks couldn't help but look at the reflection, seeing two reflections of the same person, one brunette one pink-haired, the body sizes not exactly matching.

Yet, it made a weird scene. Always reluctant to use her abilities in the bedroom, Tonks certainly didn't expect it to end up like this. Things were going in a different direction than she expected.

But, as Hermione took a step forward and pulled her head between her legs, Tonks found herself unable to answer. "Lick, bitch. It's a good way to pay," Hermione ordered.

Tonks followed her order, more out of shock than anything else. She didn't expect the famous bookworm to use a language like that … but then it wasn't the first time Tonks was reading them wrong.

Just like Harry, Hermione knew her power and used it without shame. Tonks found herself licking her. Then, she found herself listening to Harry's footsteps getting closer. She didn't need to look in the mirror to know he was positioned behind her.

As he drove his massive cock into her from behind, his hands came up and grasped her tits. Helpless, Tonks just moaned.

Teased from both ends, Tonks felt weakness spread around her body along with pleasure. It was something she wished she hadn't discovered, but she was helpless at this point.

On the positive side, she could feel her after-mission stress disappearing completely. "Let yourself go, whore," the order came, which was from Hermione. Tonks shouldn't have felt surprised, but she did.

As Harry continued to maul her tits, Tonks moaned like a whore and began to push her hips back towards his cock. "Don't forget to lick," Hermione ordered. Tonks whimpered as she did her best to follow that request. She didn't like being treated like that, but being caught in her visage, Tonks found herself helpless, unable to argue.

She was right, she owed it to her.

She tried to stay strong and continue licking Hermione's wetness, getting more intense. But, her attempts to stay calm were evaporating quickly as Harry continued to pound her, putting her through a challenge she had never met before.

Which was shocking, as it wasn't the first time they were having sex. Their kitchen encounter was explosive and intense, and at that moment, Tonks was sure it was the excitement of the first time giving him a boost. After all, how many men could say he enjoyed the attention of a veela and a metamorphmagus at the same time, a good reason for him to put in an extraordinary effort that would leave him drained for days.

But, just a few days later, Tonks was learning her assumption was incredibly inaccurate. As he continued to take him behind in a passion that put his earlier shower performance as a mere warm-up, she was struggling not to lose her mind.

It was wrong, of course, but that didn't make it any easier for Tonks to control herself — and Hermione constantly pulling her hair mercilessly just made her growing pleasure even more intense. Soon, the orgasm hit, and she collapsed.

"She seems to be exhausted," Hermione suddenly said as Tonks found herself laying on her back, breathing hard. "But what else you can expect from an inferior imitation," she added as she grabbed her tits, mauling hard. "Even after she had gone all this trouble to blow my sizes up. But maybe you like this more."

Tonks recognized the threat in Hermione's tone, and wanted to warn Harry, or at worst, distract Hermione. Even in her dazed state, she knew that it wouldn't be just as good if he actually admitted that.

Many friendships that had been ruined about such jealousies taught her that. But, Harry missed that, and instead smirked. "Oh, I have to say, her ass had been rather spectacular."

Tonks expected Hermione to growl in anger, yet she just smirked. "Oh, it seems that I have to teach you the original is always better than a pale imitation. And, Tonks watched, surprised, as Hermione walked toward Harry, pushed him down, and skewered herself with his erection.

Tonks was happy with that, as not only it didn't end as she feared, but also she had earned herself some time to recover. And she needed to recover if she were to make a logical decision about the position she found herself in.

Just not easy as she hoped, she realized as she watched him grip Hermione's hips in an iron hold while she danced on top of him, rocking again and again. Hermione moaned explosively as she took it, but that didn't prevent her hips from moving in an incredible pattern.

Tonks didn't take Hermione for a dancer, but her movements suggested a surprising elegance … and experience. No wonder Harry realized who she was in seconds.

Still, as she watched, she moved to a sitting position, glad that the focus was not on her. She shifted to a sitting position first, and when she realized they were not paying attention to her, she went to the bathroom, and pulled her robe on.

Not to mention, she took her wand once more. She had no idea what spell Hermione used on her, but she managed to dispel it with the Finite spell … though, there, she received another hit to her pride. It took several attempts for her to achieve that, showing that either the spell was surprisingly resistant to dispelling.

Or Hermione was stronger than her, making her better than her in magic.

Tonks hoped it was the former, but a sinking feeling in her suggested that it was the latter.

And, it would make Tonks inferior in another thing, if Harry's groans, much louder than anything she managed to achieve, were any indicator. A shameful defeat all around, Tonks admitted as she let her body transform back into her usual looks, but with an uncharacteristically deep blush.

Then, apparated away shamefully, the realization of her defeat hitting her hard … but luckily, she had multiple orgasms to soften the blow considerably.

Now, all she needed to do was to avoid the two until they went back to Hogwarts
