A Mock Battle in the Near Future...

As much as Byleth enjoyed Manuela's sweet titties and the ease to which her revealing dress offered them to his exploring hands, the Archbishop's concealed but very large bosom sang a siren song to his limbs and he stepped across the space between them and filled his palms with her cloth bound heavy mounds, her golden mantle obscuring them even further as Seteth continued, "In a few days' time, there will be a mock battle between the three houses, intended to gauge the current progress of the students."

Her lustrous green locks framing her perfect beautiful face, the verdant strands laying out atop her bosom, the Archbishop blushed slightly as By kneaded her jugs through the heavy layers of her complicated religious gown.

Seteth's arms were folded neatly behind his back as he watched Byleth grope the supreme leader of the Church of Seiros, his nostrils flaring, "We will be using this battle as an opportunity to ascertain your own abilities as well. Please do not disappoint the archbishop." When the stoic man spoke further, he did so with a firm declaration, "That is all."

By left then, followed by his sister. Outside the audience chamber, he encountered that pretty little greenette Flayne. Naturally, Byleth caught her and spent a decent amount of time kneading those lovely little boobs. He let her go after a few minutes, her whole face flushed pink in a way that was reminiscent of the heavy breasted Archbiship. When he released her, she smiled cutely at him before slipping into the audience chamber he'd just vacated.

Byleth spent the following days doing his best to prepare a course of instruction.

He didn't know what he was doing but he had a week to figure it out before classes started. He didn't feel particularly qualified to teach and on the face of it, the whole idea was absurd. But he didn't let the pressure bother him. He'd do his best to impart what experience he did have with combat and warfare as a successful enough mercenary. For the teaching aspect, he had the Church's expansive library as well as the resources his father and the other teachers' represented. So he spent his days split between reading various treatises on the proper way to educate the noble youth, histories of past battles, et cetera and interrogating Jeralt, Professor Hanneman, and Professor Manuela.

Manuela...

Now there was a fine woman...

In truth, he had only sought her out for advice but she'd taken his seeking her out in her room as something else entirely, praising him for being a 'man who knows what he wants' and asking him to lock the door. Given his lustful nature, he'd went along and it was not long at all before he was playing with her soft hand-fulls, slipping them out of the sheer top of her dress with ease. She wore no undergarment and it was child's play for him to bring her to climax with his hands.

Naturally, they'd had sex then. Manuela made her interest and desire imminently clear as she vocally narrated the progress of his growing erection down his pant-leg. Within twenty minutes of their encounter, Manuela was lying on her desk, her feet were in the air and her knees pushed against her tits as Byleth’s shoulders bore down on them, as as he pumped his lengthy prick inside of her as she breathed deeply, “Oh, yes. Fuck me.”

It turned out that Manuela was a very experienced woman and she was ready and willing to be mounted in every way that he desired. He took her on all fours beside her desk. He plunged into her with his hands grasping her buttocks as he stood, her body split and wailing as he drilled her. He took her on her side upon the couch in the room, he squat down low to plunge into that wet and yielding cunt.

One night, Solis appeared and she spent a good half-hour avoiding answering his questions with anything other than avoiding tactics and cryptic responses. Fortunately, while she was imminently frustrating in some ways, she was rather more accommodating and enjoyable in others. Ask her about her nature or how she'd reversed time and she'd yawn and complain about his manners. Ask her to lay back and spread her legs and she'd happily comply and encourage him to do his best to give her pleasure.

Other nights he found the servants that worked the monastery to be just as willing to spread their legs to him, his efforts at seduction seemed to find success without fail. He attributed it to a commoner's natural inclination to social climb as best she could with the weapon that was her fertile womb though he recognized the petty gossip of his endowed member and sexual virility that was no doubt spreading like wild fire since his first tryst was partly to blame.

Deneb did not share his concern about living up to the responsibility the Church of Seiros had thrust upon them. Every-time he encountered her over the course of the week, she was her normal irrepressible self, either napping in absurd locations or regaling him about her own attempts to sate her lusts. She had an entirely laissez faire attitude about their situation which seemed to be matched by her house leader, Claude. It seemed that she had latched upon the red-headed Leonie as her current crush. The commoner girl worshiped their father and was a consummate mercenary. Naturally, she shared Deborah's powerful libido but her proclivities were fully towards men rather than the either/or that his sister ascribed to. Based on Deneb's complaints, Byleth got the distinct impression that the only one who could woo the short-haired lance enthusiast was their dad.

By wished her luck but he knew that she was doomed. Jeralt was devoted to their lost mother, even now twenty years later.

On Thursday, he was summoned by Professor Hanneman to study his crest. He'd been forewarned by Deneb as she'd been asked to the mustachioed scholar's rooms the night before. She'd crashed and burned at seducing the steady researcher. She'd insisted that that learned man had to be interested in men rather than women but the handsome man had showed no interest in Byleth's manhood. Instead, he'd been absurdly excited by By's crest, though he'd kept whatever he'd learned from his experiments to himself.

On the day of the mock battle between houses, Byleth found himself within the Black Eagles' command tent, his students on the outside preparing for battle. His absurdly irrepressible sister was inside, taking this moment as seriously as she took anything.
