She begins to "make it work"

Kostas had always set his sights high when it came to women. The heir to the Adrestian Empire… He would’ve loved to see her brought low and be the one to pump a new heir into her belly. Recently however, he set his sights on another: a certain mercenary-turned-professor who had robbed him of that prize. Through her actions he was bound and dragged to Garreg Mach, fearing the day that his life of banditry was always leading to had finally come…

But the events that followed were not something he had ever expected: Lady Rhea, head of the Church of Seiros herself, not only revealed to him that he had a crest, but granted him a position as a knight under her service. It was as though the goddess herself was toying with the world, giving a man like him such a fortunate twist of fate… it was kind enough to even grant him that mercenary girl: He approached her room, curious just how effective this power of his was.

Imagine then his surprise when not only did she save him from one of the nosier students, but then was invited in to her room. She didn’t seem to resist in the slightest, eventually asking him if he would like to take her virginity. It was the first time they had even really spoken to one another, but he still clearly envision himself with her, as though he had taken her before... Even now it felt as though she was sucking his cock, her warmth enveloping him. There was a sharp pain as well, short but fierce. He groaned, trying to move, but felt stuck. He tried again, pushing through, before eventually managing to open his eyes.

Daylight filled the chamber, Kostas’ eyes wearily adjusting to the dawn. Sleep clung to him, keeping him from figuring out exactly what it was he was feeling, but it was... wonderful. It was strange for him to feel linens under him, the bandit so used to sleeping in the wilderness, but whatever he felt was more than that. He finally managed to focus and that’s when he saw the woman he took to bed the night before now servicing his cock with her mouth. For a moment he thought he was still dreaming, but no dream had ever felt this good before - this was real. Kostas chuckled, a staggered laugh that eventually grew into a hearty guffaw: to think that his fate would take such a turn…

Byleth had carefully managed to position herself near the foot of the bed to lay in between her partner’s legs. Resting on her stomach, she propped herself up onto her elbows, making sure to move slowly and deliberately: she wanted to surprise him, to have him wake up to her ministrations and see just how good she could be to him… especially when unprompted. Now in position, she began to tease him with her lips and fingers, carefully bringing him to full mast before he even began to stir. It was a magnificent sight.

Once he did begin to stir she got to work, pumping him with her hand and occasionally sucking on the tip, all while making sure to look at him, hoping that her eyes would be the first thing he saw. The taste was unlike anything she had experienced before last night… that fixed turning point in her life. She had woken up and wondered if she should have used the pulse and return just like she had done so before, but the truth was, the moment she fell asleep it was too late. Her Divine Pulse was able to take her back only so far, an hour-or-so at most. And so, if there was no turning back, she thought, why not make the most of it? She redoubled her efforts, bobbing her head and digging her fingers into his thighs, actively trying to wake him up at this point.

Kostas groaned, and Byleth watched as the mountain of a man finally came to. She watched him carefully, managing to time it just right, so that the first sight that greeted him was that of her hand cradling his hefty member and her tongue gliding up all the way from the base. Again she licked his length, and again as she saw recognition in his eyes before… he began to laugh. It caught her by surprise at first, but eventually she too couldn’t help but giggle, her smiling face resting next to his cock as she slowly worked it with her hand.

“Oh, ho… you are a special one aren’t ya?” he said, brushing a lock of hair out of her face. She didn’t even feel the need to respond, simply going back to pleasing him within her mouth.

It took some effort to continue looking at him while sucking him off. It made her pace slow but, in a way, this made it all the more intimate, his hand now resting on her head. Every time she went down, she could feel him push on her slightly, but it was nowhere near the wild control he exerted before. Still, it reminded her of last night…

Byleth thought that she was simply indulging, that she would turn back time as soon as she was done. She still had two more charges; she could have done it all over again and still had a chance to go back. Yet here she was, the morning after. When he **** himself upon her that first time, she went back, but after having given in only once had she failed to undo it - that she had fallen. A pang of guilt and shame grew within her, but as his hand brushed through her hair, it began to fade. He was smiling, but not in a way she had seen before, it didn’t contain the same brutish lust it seemed to have before, and Byleth noted how unusual it was to see him like this. A fluttering sense of warmth blossomed down below and deep within her.

Despite everything, whether it was an accident or some part of her that decided to fall asleep, she was quite pleased with how events unfolded...
