Play Nice

Gwendolyn could only gawp at the monster dangling in front of her. She considered her options carefully, but she knew at this point resistance would be pointless, she’d just have to bide her time. So very gingerly she edged her face forwards and wrapped her lips around Victor’s cock and pumped her head backwards and forwards.

Normally Victor would have been more aggressive, but seeing as Gwen had skipped past giving head, he was content to allow her to continue at her pace. Make her think she has any semblance of control, making the inevitable that much more satisfying. And he had to admit; watching this proud and strong woman **** to service him was more than enough to satisfy him.

“That’s better,” Victor growled. “Aren’t things nicer once we cooperate?”

On Gwen’s end she has having a hard time denying her attraction to the German. A succubus could only deny her nature for so long, and having such and well-endowed man in front of her was ticking all the right boxes in her mind. She began to take him deeper and deeper, and she continued to breath in his musky scent. If he wasn’t borderline evil, she could have seen this becoming a more regular thing.

She began to reach her limit as the head of his penis began to hit the back of throat, but Victor was quick to encourage her further by grabbing the back of her head and forcing her just a bit further. It would have been easier to break Blair, but it would be far more satisfying to turn Gwen into his personal sex ****.

“That’s enough, let’s see how those tits feel with something between them,” Victor commanded. He stepped backwards to allow his erection to fall out of Gwen’s mouth and flipped a button on her chair. Suddenly the back of the seat fell backwards, forcing Gwen to lie prone on her back. Victor – being so large in more was that one - quickly straddled her with ease and rested his cock between her breasts.

“You’ll help me out, won't you?”

Victor flipped another switch and Gwen found that her arms were now free. So many thoughts rushed her brain at one: Could she attack now? Should she throw a strike or hit him with magic? Was she strong enough right now? However the heat of the moment had overtaken her, and her succubus side was starting to get the better of her.

She raised her hands and grabbed her big breasts; squeezing them around Victor’s shaft. While not used to giving titty massages, the young woman quickly picked up on the technique, squeezing her breasts up and down. Victor then began to hump her chest in turn.

“There we are,” Victor chuckled. “You’ve been blessed, girl. It would be a shame not to use your assets to the fullest.”

“Ugh,” was all Gwen could say in return, trying her hardest to sound as appalled as possible. But deep in her loins she could feel something calling out to her, a little voice in the back of her mind telling her to embrace the seed Victor would give her. But she would never show that side to Victor; she wouldn’t give him the satisfaction.

… But she still felt the need to lock her lips around Victor’s pulsing member while he fucked her breasts… To keep Victor quiet of course, she was just moaning along so he’d let his guard down. Yeah, that was it.

The two moved in tandem as their grunting and movements became more erratic. The sensation was difficult to describe for Gwen – feeling a cock between her boobs should give her little to no sexual pleasure – but judging how wet she was, and how her horns were edging to appear, something about being dominated like this was turning her on to no end.

“Enough foreplay,” Victor grunted. He practically leapt off of Gwen and headed towards her lower end. Gwen felt a sense of panic when she saw how fast Victor was moving, but she was no longer in a position to fight back. She moved her legs apart without even a command and without any fanfare; Victor shoved his prick past her entrance.

“Oh shit~” Gwen moaned under her breath. She pinched her nipples instinctively as she felt herself get invaded by her enemy.

“Look how wet you are,” Victor chuckled darkly. “I’m always in need of some fine sluts to fill my ranks. The men can get restless. Interested?” Victor pushed himself in further.

“F-f-fuck you,” she breathed out in response.

“No point in acting coy now,” Victor countered, starting to move faster with each thrust.

And the more he thrusted into her, the more Gwen felt she was going to change. Her yellow iris began to dominate her eye, her back began to itch with her sprouting wings and her horns began to poke out of her skull. Victor was so consumed with his fucking that he didn’t even notice that the succubus was transforming before him.

“Oh god… not LiKe ThIs…”

Gwen lost control. Her wings unfurled, her eyes were a bright yellow and her horns curled around her skull. She looked up at the man before her and realised in her new state that she could at least turn the tables.

“YoU dArE aTtEmPt To DoMiNaTe Me MoRtAl!? I wIlL hAv- AHHHHHHHHH!”

At that moment, Victor quickly pulled out and a sharp electric current coursed through Gwendolyn. All at once her bodily transformation began to reverse itself. Her horns had vanished, her wings became limp and fell off and her vision was clear once more. After the shock wore off, she looked herself over in total shock.

“What the fuck!?”

“So the rumours were true; you are indeed half-succubus. How delightful.” Victor roughly grabbed Gwen by her neck and smacked her right across the face with a pimp hand. Gwen was knocked loopy again.

“H-h-how?” She squeaked out.

“Magical reverse engineering. You aren’t the first subject I’ve captured my dear. I have observed others of your kind as they transform, and all I needed to do was tweak the nerve in your system that activates your secondary appearance. Once it’s disrupted, you transform like when your brother’s cock when a woman propositions him; they both go limp.”

He dragged her by her neck and slammed her chest first onto one of the far science tables. He **** her legs apart again and positioned the head of his penis against her backdoor.

“You will continue to make a fine test subject my dear… and later, an excellent pet.”

“AHHHHHHHHHH~”

Marty could hear Gwendolyn moaning loudly. He slowed his pace as he stepped out of the lift. He looked around and noted that he was in some sort of reception room before a laboratory. It was stylish and clean, with a white and red aesthetic. There was also a random staircase that seemed to lead to the roof.

The young man walked towards the door and took a peek to see what was happening. A large bald man in a white coat was fucking Gwen on a table. The motion he moved in was like a piston moving in and out at a brutal speed. Looking closer, Marty could make out the large size of his cock, making his own look quite small in comparison, despite being at a pretty good size. Gwen seemed to be in a state of both pain and pleasure, unable to escape from the man who was pinning him down.

For a moment, Marty imagined himself in that position. Bound and helpless and unable to do a thing as someone took complete advantage of him. He swore his mind was taunting him as he envisioned himself being held down, bent over a table and rammed into until he had no desire to resist. The loud wet slapping getting louder reminded him what he had to do. He just wasn’t sure how to achieve it.

He stepped through the doorway, keeping to the back of the man in the white coat. Marty positioned himself behind a table and scanned the room. To his left was a pipe that had been left on one of the lab tables, likely after a plumbing accident that hadn’t been fixed. To his right however, was a handgun. The man in the coat must have left it as he began to **** Gwen. He had to grab one and hope that it would be enough to finish the large man in front of him.
