Demon Lord Shapeshifting System



"Mnfh! H-Harker, that hurts like hell— Ah!"

Joan moaned with her head buried on the covers of her bed. She was breathless as she endured even more hits on her bubbly ass, the red handprints turning into shades of purple by now.

But she didn't stop Harker. Harker said that if she truly wanted him to stop, all she had to say was….

'Edmund'.

She thought it was very cruel of him to do that, but she did understand. Harker wanted this night to be for him, and no one else. And she knew she wouldn't call out that name anyway, whether on purpose or accidentally.

She wanted to fully give herself to him, and only him.

"It's weird to have the student be disciplining the teacher, but here we are. Former student, but whatever." She heard his voice from behind her. "And seeing how you just keep getting wetter, it's safe to say that our dear Professor Joan enjoys it."

Joan thought he sounded so different when he teases her. It was gruff, with undertones of both mischief and malice. It gave her a whiplash, but it wasn't really a bad thing. She loved to see this side of Harker so out in the open now. She did witness it a few times, especially that time when he licked her bleeding figure back at her burned home in Virginia….

But this was that going at full throttle, and he just kept on being more sadistic by the minute. 

Harker was aware of it too, and he had no way to describe this moment. He did not have to think of what to say, his mouth just speaks for him. He didn't have to think twice on what to do, his hands moved on their own to slam themselves on Joan's ass cheeks without hesitation.

"What's that? I can't hear you, Professor." He could feel his own lips stretching into a wide grin.

Joan made more muffled sounds on the bed before Harker lifted her head up by force. Of course, he did so by pulling at her hair. 

"Fuck me now, please!!! Just fuck me now, Harker!!!"

Harker frowned. "But I'm not done with your punishment. You cummed even when I told you not to. And even now, your naughty pussy keeps on leaking."

"I won't again, I promise….. Also, why the fuck are you calling me Professor again!? It just makes this even more embarrassing for me— Ah! Ah!"

Harker pushed her head back down and spanked her again. 

"I thought I could do whatever I wanted. So that includes calling you whatever I want, right, Professor? You're not used to having someone else take control over you, huh? Both as a teacher and…. well, with all those men you bedded with."

Joan did not answer, or perhaps she could not. Harker decided that both were good either way.

He leaned closer, whispering to her ear. "No…. You were a skilled vixen, having many experiences and all that. You could easily make any man fall into submission. But I know deep down you wanted to submit yourself to someone who could handle someone like you."

He pulled on her hair again, and Joan was hysterically sobbing now and begging. "YES! YES! That's what I want!!! Do it now! Make me submit!"

Harker smiled, but nothing like that warm smile he usually wears. He knew how callous this smile was, but at this moment…

It didn't feel bad to wear it. 

"As you wish. You better thank me for this, Prof. And I want to hear you loud and clear." 

He grabbed onto her neck as he inserted himself into her cunt, going hard and rough with no preparation at all. Each time he penetrated, he did it so deep that it bulged out onto Joan's stomach. 

He bit into her shoulder as he pushed in and out. This was almost identical to what he dreamed of doing, except that was in a musty cave and this was on a poor bed that was threatening to break any second.

And the frame was even made of metal. It creaked so loudly that anyone in the building would hear, but Harker didn't care. He kept going, keeping his tight grip over Joan's body.

Joan was choking now, and yet she managed to obey his orders earlier with her tongue out and eyes rolling to the back of her head:

"Th-Thank— Cough! Thank you! Oh, thank you, Harker…. Cough… For fucking this pussy... Keep fucking me harder..."

Her body was really good for her 'age', and especially so for her real age. It was actually like fine wine that just gets better over the years. Harker couldn't get enough of it, wanting to see how far he could go with her unyielding submission.

She couldn't die anyway, but he could destroy her body.

Tempting as it was, he felt that he shouldn't. He can go really, really close to breaking her walls literally until he had torn her insides, but he shouldn't actually do it. Not on the first time of her submission.

Still, he was willing to leave that bite mark that left scars for weeks, maybe even months if he kept biting there every single time. He liked seeing it, as it was a symbol of how for this night and the rest, Joan was his and his alone. 

"I'm going to cum inside you, Joan... I'm going to fill you all up until you explode…."

He knew that wasn't possible, but he did pretty close on fulfilling that hyperbole. He unloaded so much that his own cum started to leak out from Joan's fucked-up cunt and onto the bed. It mixed with some blood, but neither of them minded it. He didn't pull out until Joan was groaning about how full she already feels. 

"So much... You're shooting up a whole generation in there, Jones." She muttered, though she was close to passing out. 

"It's not over yet." Harker said. "Let's keep going until morning."

And they did. Just like animals driven by nothing but libido. 

That was how it went at nighttime. In the morning, though…..

As Harker smoked the cigarette, actually his first time to ever do so….. He felt the same way as when he got sober. And he can count on one hand how many times he got drunk.

He can't afford to get hangovers and party as a scholar/ part-timer/ exemplary son and brother after all. It was nice, but the somber feeling was hard to describe after it.  It was not just post-nut clarity, but even deeper than that. 

"Now I understand what he said before." He chuckled as he opened his eyes. "That a man is driven by his urges. Even if you do have your wits with you, no matter how logical you are, unless you really don't have a sex drive…."

He looked at his morning wood that was up again. 

"The urges will come no matter what, and you'd have to take care of it somehow."

So he and Joan went at it again. While they were in the middle of it, there was suddenly a knock on the door….

"So this is why you weren't in class, Ms. Joan." They heard a familiar voice behind it. 

Harker's eyes brightened at this, and went to open the door in a flash. He picked up Mina, kissing her until she couldn't breathe, and laid her on the bed. 

She just chuckled. She experienced a bit more of Harker's sadism beforehand, and even stoke the fire sometimes. So she wasn't fazed by the sudden aggression at all and was inviting towards it.

"Hahaha, what's this? Why is Ms. Joan skipping Biology class and you guys are having fun without me, hm?"

Harker kissed her hard again. "You're free to join us. Fuck biology, let's all explore each other's anatomy."

That's exactly what they did for the whole day. By the end of it, Harker fell asleep with their hands around him, his libido very satisfied.
