Chapter Text
Byleth had dreams of the same green-haired girl, Sothis, almost every night. Now that the rebel defilers had been driven from the Holy Tomb, and the Sword of the Creator was in his hands, those dreams only intensified - adding more confusion to an already confusing situation. Byleth had been a young, talented professor at Garreg Mach monastery, instructing the best and brightest of Fodlan’s future elites, but that all changed when he found himself entrusted with a holy relic - one that had changed him physically in ways he hadn’t revealed to anyone.
Except the green-haired girl. She called herself Sothis, and perhaps by virtue of her being present inside his mind (in a way neither one of them quite understood) he seemed incapable of hiding anything from her.
“Well, I didn’t expect the Sword of the Creator would have this effect!” she said. In his mind’s eye they were in a stone chamber, and she was reclining on a throne of inlaid stone. She talked like a stilted grandmother but had the appearance of a long-haired teen female.
In the dream, Byleth stood across from the throne, armored and dressed as was typical for his instructor duties - except for the breeches. He was totally bottomless and feeling the breeze, with his cock totally exposed. And what a cock it was! The Sword of the Creator’s blessings apparently included an endowment that was beastly in size - a cock befitting the godlike ancient powers that had allegedly forged it.
Sothis floated off of her throne and settled in front of Byleth like a blown leaf, reaching out one arm to grip the hanging shaft. Her small hand could not even encircle the girth. “I should know what this is,” she said, mostly to herself. “A penis! Yes, that’s it. Males have them. How could I forget that? My memory has so many gaps!”
Byleth gritted his teeth as the small but beautiful girl investigated his hanging fuckmeat. And it really was hanging. The shaft was very much unlike the rest of his bishonen body, in that the skin was ruddy, veiny, and textured here and there with bumps. Around the rim of the glans a ring of hard boils promised to scrape and abrade any partner, for pleasure or worse. It seemed to constantly be leaking cum, and a thick foreskin covered most of the head. How long was it? As long as Sothis’ slender arm from fingertip to elbow. The length of one of the rulers in the Garreg Mach classrooms, and perhaps longer.
“Do you feel any different, now that you have this thing?”
Byleth nodded. He did feel different - is “constantly horny” counted as different. Officially he was head of the Golden Deer house at Garreg Mach, but each of the three houses was absolutely stacked with beautiful young female students who, because of his sudden recruitment into teaching, were close to his age. Sothis moved her hand up and down experimentally, pulling the skin of the shaft back and forth. Byleth winced with pleasure and there was a wet, spurting noise as a sloppy spout of pre-cum sprayed down onto the floor, causing Sothis to recoil at once.
“Oh! What was that?” she asked.
Byleth explained the human reproductive system.
“I see,” said Sothis. Her eyes betrayed a sudden, naughty interest. “And that means you’ll use that on the girls here?” She looked thoughtful, if a bit oblivious to what that meant. “I have a faint notion that something is supposed to be reborn. Perhaps this is how it will happen.”
Byleth explained that he couldn’t just walk up to the many girls at Garreg Mach and start fucking them. For one thing, they might not want that. For another, he was their teacher. Third, his new, Sword-enhanced penis was so large as to be rather embarrassing.
Sothis brought her finger to the tip of Byleth’s massive, flaccid endowment and rubbed the digit there, bringing it away coated in whitish-yellow, gooey pre-cum. “It’s so thick!” she remarked, and then wrinkled her nose. “And even in this shared place, where I’m locked away inside you, it fills the air with an odor! I can’t even describe it. It’s very pungent!”
Byleth shrugged helplessly. Sothis, perhaps owing to her strange ephemeral nature and lack of memories of human behavior, extended her tongue and licked at the substance, immediately reacting by turning her head and squinting her eyes. “Ugh!” she complained. “It tastes disgusting! Yet somehow… I don’t hate it.” Her face seemed to have taken on a strange blushing quality. “I’m sure of it,” she went on. “This is the method by which we’ll play a role in Fodlan’s future peace. Don’t you think so?”
Byleth remarked that he couldn’t see how a huge, virile penis could play a role in Fodlan’s future affairs.
“Your students,” Sothis insisted, seemingly growing impatience with Byleth’s reticence. “They’ll be looking to you for guidance. You must bring them together, and together find the shared destiny that I sense in their future. Be cautious if you have to, but don’t be afraid to rush ahead, either - we can use Divine Pulse to undo any mistakes.” She reached out to caress Byleth’s cock again, running her palm down the side. “Use this thing to bring your students under your control and keep them safe- oh! It jumped!”
Indeed it had. Even in his own dreaming mind, Byleth’s cock was becoming hard. Sothis looked somewhat perturbed, cocking her head to the side and putting her hands on her hips, an expression made more accusatory by her pointy, triangular ears being askew. “Hmm! I see you’re already planning what you’re going to do. Are you thinking about that Edelgard? I sense she was quite a role to play in rebirth.” Sothis began to slowly jack Byleth off with her small hands, looking up at him earnestly. “I’m certain that one of these girls will be responsible for the Goddess’ return. You must keep them close to you and make sure they’re ripe to the task!”
Byleth moaned as his cock rose to a horizontal position and Sothis kept jacking. “And when the times comes,” she said, in her melodic voice, “you must use this to plant the seeds of Fodlan’s future!” Cum was leaking all over her hands, and she wrinkled her nose again. “Ugh! It smells so foul, and it’s producing so much of this messy, thick goo! And what’s with this loose skin at the end? It stinks!” She reached underneath with one hand to grope Byleth’s testicles as well - each one too large for her hand to hole and hanging low, nasty and fat in loose ballsack. “Are these were the substance is made? I can feel them churning! Like they’re making more this very second!”
Byleth groaned and uncorked a fat blast of cum directly into Sothis face, splattering her regal, youthful features with yellowish ball chowder. It went everywhere - her mouth, cheeks, nose, even her wide green eyes! He was hosing down the presence in his mind’s eye with a huge, degrading load!
Just as this was happening, though, he jolted awake in the bed, inside his quarters at Garreg Mach, breathing hard. A quick lift of the coverlet revealed that his huge penis had spewed what seemed to be a half-gallon of lumpy, off-white semen all over the sheets.
Byleth sighed. He thought of several things he might say at the moment, but none of them seemed like they would change his strange situation. He began to rise out of his bed. It was, after all, time to meet his students.
Support Rank with Sothis became S!
