A gasp left Tonk's lips as he pushed forward, slowly parting apart her puckered hole, forcing her to come to a decision quickly. The safe word had put her in a dangerous dilemma. She could play along, but without a safe word, she would end up as his toy…

Or, she revealed her true identity and saved herself from the humiliation … but that would mean stopping, which wasn't as attractive as Tonks wished to sound, not when her earlier show worked well to get her body running. And, if she were, to be honest, his presence pressing against her ass felt good.

But, was that worth the humiliation? She could feel him grinning at her from behind, treating her like a toy. And, it was just a start. She might be horny, but also she was an auror, and her pride was important. Should she accept that?

She needed to decide quickly, however, as he continued pushing forward. It wasn't the pain that she was scared of, as her talents allowed her to control her body perfectly and the spell he cast as he started pushing helped even further.

The longer she waited, the more absurd the situation would become.

Yet, she delayed … until a flash of inspiration hit her. Why did she worry about humiliation, when she was disguised as Hermione. Anything that happened didn't happen to her, but Hermione, so she didn't have to worry.

It was a bit of a stretch, but as he pushed deeper recklessly, radiating pleasure, she found her own argument rather convincing. With her hesitation gone, she pushed herself back, helping to his invasion. She took all of him inside.

She cheated only a bit, hoping that it would go unnoticed.

It did not.

His hand landed on her ass, forcing out a loud moan of her. "Why are you this loose, Hermione. Don't tell me that you were playing with yourself before you arrived. You know I don't like it."

"Sorry," Tonks whispered.

He spanked again. "I won't want empty words. Clench your beautiful ass so I can enjoy it," he ordered.

Tonks could feel the blush creeping over her body, glad for her disguise. Yet, she decided to follow his request. "I'll show you tight," she whispered.

"Did you say something, slut," he whispered as he spanked again. "Speak louder.

"No, nothing, just a moan," Tonks answered, even as she changed her body to follow his request, just more intensely than he expected, trapping him in her tightness.

The moan he let out sounded spectacular.

Admittedly, it wasn't exactly without consequence for Tonks. By tightening herself, every push of his hurt much more. She prepared herself to hate the feeling, but to her surprise, she found herself loving the feeling.

"Damn, girl, that's what I'm talking about," he said as he reached forward, and cupped her oversized breasts. She was still wearing her shirt, but the fabric was already thin before being drenched, turning useless. "It's not as good as usual, my sexy bookworm, but I guess the mission was exhausting."

Tonks should have felt excited, but she was busy feeling affronted. Here she was, enhancing what Hermione could do with her supernatural talents. Yet, the best she got was it was below usual. It was an insult to her metamorphmagus talents.

And an insult to her first name.

Growling in anger, she pushed him back and fell to her knees, determined to show him. As she fell down, she caught his gaze, watching her in amusement. She would soon change that into a desperate moan.

She took his monster to her her hands and stroked it a few times, more of a habit than anything else, as the spell made sure there was no need to clean. Though, her eyes were still fixated on his shaft, taking its size.

Maybe he also had some latent metamorph talent.

She would have loved to play with her a bit more, but she had a self-assigned mission. She took his girth between her lips and pushed forward, taking him into her throat … with a bit of challenge. She could have transformed her throat to accommodate him easier, but it would be suspicious.

She grabbed his legs, and pushed her head forward, as fast as she could manage. Her determination was strong … too bad his brute attitude took her chance. Before she could even start, he grabbed her hair, pulling hard as he fucked her face mercilessly.

When he pulled back, black spots were dancing in her vision. She breathed hard, desperately. "Come on, Hermione, no wasting time," he said as his hands slid lower, and ripped her shirt off. "Since you went all this trouble making them bigger, you can use them while you're taking an unscheduled break."

Tonks sent an angry glare at him, but she did her best to erase it when she noticed his surprised glare. Clearly, what he was doing was a part of their routine, and Tonks needed to play along.

Or she would get caught.

Tonks avoided his gaze as she continued to kneel before him, his huge cock ready for the next step. She was glad that she exaggerated the size of Hermione's bosom, giving that monster what it needed. Leaning in closer, the fake bookworm wrapped her breasts around his thickness, moaning wantonly as she rubbed herself against him.

To her shame, her horny moan was completely genuine.

"That's a good girl," he commented. She felt like he was mocking her, but she didn't dare to raise her gaze, not when she almost avoided getting caught. She bit her lips and focused on her task. His hands dipped down and landed on her tits, enjoying their great expanse.

As the pleasure hit, she realized they were more sensitive than she planned, but she didn't make any attempt to change it. Not when he was mauling them, the softness pushing her toward an orgasm far faster than she thought to be possible.

He knew his way around a woman's body far better than a man younger than her should… Not that she was complaining.

She just focused on the rhythm of her task, lowering her head to capture the head, and adding another layer. In response, he grabbed her hair, adding another layer of pain to their little game.

As much as she hated to admit it, she loved it. She loved it enough that, when he twisted her nipple once more, she started shuddering, her eyes rolling back. She felt her whole world shift as she kept her eyes closed, enjoying the sensation.

Then, she panicked. The sensation felt like her shifting. Could it be that she lost control of her transformation?

"Don't tell me you climaxed just from that, Hermione," he said. That made Tonks relax. Her transformation shouldn't have slipped too much if he was still referring to her like this.

Of course, she didn't need his words — or a mirror — to check the way she looked. It was one of the perks of her skill. She just needed to focus on her body for a few seconds and concentrate, and she would visualize the way she looked, allowing her to maintain her looks without suspicion.

The problem … she needed to concentrate for a few seconds, which was impossible to do as she still trembled after her explosive orgasm. She didn't let go of his shaft, keeping it wrapped by her tits, not helping her to calm down.

Her chest still heaving.

It certainly didn't help when he pushed her on the floor, her back pressing against the ceramic floor. Especially when he followed by sliding into her ass once more, not even giving her a chance to adapt. "Tighten, you whore," he ordered.

Helpless, she did that as she spread her legs wide, allowing him unobstructed access to her fat ass. If his grin was truthful, he enjoyed the access she provided as his hips moved, his hands tight around her hips…

The wet sounds of their hips colliding filled the bathroom, each collusion working as fuel to her arousal. She wanted to push her hips forward to meet his movement, to make it more of a dance … but the situation didn't allow that, not when his hands were tight around her hips, pinning her in her place, impossible to move.

Leaving Tonks to show her feelings in whimpers and moans as she got the full treatment from his cock. "You're louder than usual today, Hermione," he said, showing that she was not playing the role as well as she might have wished. Luckily, he wasn't observant enough to connect the dots, or she would be in trouble.

Tonks kept her eyes closed, surrendering to the pleasure of his reckless invasion. She was so glad that she had decided to disguise herself and take Hermione's place … she might even consider sneaking into Hogwarts during the school year if that was what the bookworm was getting regularly.

Lost in pleasure, it took a second for her to recognize the distinctive click of the door opening, and she only realized that when the intruder spoke. The intruder with a very familiar voice …

"So, Harry, do you want to explain why you have a pink-haired copy of me," Hermione Granger called.
