For a good while

Catherine couldn't do anything but continue to suck, no matter how demeaning it felt to do so or how humiliating the situation was for her to be redused to this, especially in a public area, where anyone could walk in and see them. Still, despite everything, she couldn't do anything but keep sucking, feeling the foreign power penetrating her mind, slowly seeping in and permeating her thoughts, filling them with ideas of submission and surrender, shivering a little and distracted thanks to the cold evening wind on her naked body.

And while it wasn't absolute it it's power yet, Catherine did find it very hard to resist, especially after the bandit had beaten her like that in the spar. She prided herself in being strong enough to protect Lady Rhea, and she had just been defeated by some common bandit using basic fighting techiniques, reduced to sucking his cock, almost willingly, after said defeat.

A blush came onto her face as she saw Kostas smirking at her, looking down at her, an air of superiority about him even with his messy, unwashed appearance.

"Heh, looks like this monastery's just full of sluts, huh? First that new teacher practically begging me to fuck her and now this! Go on, whore, keep sucking it!" he said to her, and Catherine felt compelled to obey, even as she blushed from those words, especially at being called a whore....she was acting like one, wasn't she? Sucking his cock after he defeated her, not even resisting him, just as she hadn't when he stripped her.

The cock reached deep inside of her, filling up her mouth and reaching her throat, causing her to gag a little and cause noises she was sure the bandit was enjoying a lot, especially from the look on his face. And she was even speeding up without being commanded to! Willingly sucking him off as she felt the part of her that qanted to resist slowly growing weaker, under **** from an unknown **** within her mind, which semeed to only grow stronger the more she sucked on his cock, his hands on her blonde hair, guiding her and making her feel even more degraded.

Eventually, after about ten minutes of this humiliation, Kostas pulled back, his cock leaving her mouth as he smirked down at her, a string of saliva connecting her mouth to it's tip as she almost felt...empty.... like she was missing something she needed. Her blush only grew worse when she realized what it was she was thinking, doing her best to glare at him even in this state, though it wasn't very effective on Kostas, in no small part because of the blush and the fact she had just spent several minutes willingly sucking him off, despite her words from earlier.

Still, he knew he might not have much time, if anyone were to walk in, and he wanted to sample another of Catherine's holes before he was done, so he wasted no time in making her lie down, his touch causing her to squeal a little.

"W-wait! What are you doing?!" she asked, suddenly panicing as some clarity returned to her mind and actions now that the cock was out of her mouth. Still, she could still see it and still feel the draw it had on her, no matter how hard she wanted to look away and run from him. She felt frozen, sitting still on the floor as he got on top of her, the cock aimed straight at her pussy. She shivered again when she felt it rubbing against her entrance, once more failing to even resist in the smallest manner.

And to Kostas, that was as good as her begging him to fuck her, especially with how feisty she had been acting before their spar. A sign that she had already submitted to him, accepted her place underneath him and the fact he could use her whenever he wanted. After all, if she wasnt resisting despite how she'd been acting before, she clearly had already given in and learned her place, just like that professor back in her room.

As such, he quickly thrust inside of her, groaning at her tightness, her pussy squeezing his cock hard, almost as if trying to **** him out, though the only effect it really had was giving him more pleasure as he pushed deeper inside of her. And as he did this, Catherine felt the fog in her mind return, much more powerful now than it had been back when she'd been sucking his cock, now making her mind hazy as she had a hard time thinking anything beyond the pleasure she was getting, a slutty moan leaving her lips.

Catherine did feel vaugely humiliated, especially when she moaned more and more, but in this state, she couldn't quite remember why she felt that way, only that she did, and that she coudn't stop herself from moaning as this man started to pump into her, using his strenght to to thrust deep inside of her, every thrust causing her body to shake as pleasure stabbed across her body.

"If every female knight and teacher is as slutty as you or that blue-haired slut then I'm going to have a lot of fun here", Kostas said, grinning as he fucked her. Catherine was not only tight, but she had an absolutely fantastic body, his hands already busy groping those large breasts, squeezing and feeling them up, which made things even worse for Catherine, the pleasure clouding her mind as Kostas' crest wormed it's way into her, planting it's seed of power inside of her just as it had with Byleth, though the process wouldn't be complete until he came inside of her.

For the time being, though, he was content just fucking her and hearing her moan, her body squirming from the stimulation of being fucked like this on the training grounds' floor as her mind was assaulted again and again, her defences being worn down bit by bit as her moaning filled the thankfully empty area.

Kostas happily continued to plow her, though eventually he felt it coming, a climax approaching, and he sped up, thrusting even deeper into the blonde knight, to enjoy a bit more before he finally came. Groaning, he made one final thrust deep inside of her, his cum shooting out and filling the lust-addled Catherine up, who could do nothing but continue to moan, her back arching as she also came, pleasure shooting across her body as she felt utterly and completely powerless, while at the same time, a glowing red tattoo made itself known above her pussy, a bit dimmer than Byleth's own, but clearly there.

He grinned when he saw it, marking yet another monastery slut as his own as he groaned and finally pulled out, putting his clothes back on as he looked at the slut that was still on the floor, panting and looking up at him with a confused gaze. Smirking, he decided to carry on with his plans.

"I heard you were pretty chummy with another knight, right, whore? As soon as you're done being a whore, clean yourself up and lure her to one of the back alleys of the monastery near the market, a nice isolated place where I can claim her like I claimed you, got it?" he told her, and Catherine, despite everything that had been done to her, smiled a little and nodded, despite screaming on the inside that she needed to warn Lady Rhea and the others about this man. Seeing this response, he walked away, feeling he'd trained enough and wanting to claim Catherine's friend too.

Support level between Kostas and Catherine went up
