Secret | #OmegaSylvain26
Pre-timeskip Sylvain inside a confessional. He's hunched over, sweatily gripping the seat with both hands, flushing and gnawing on his bottom lip with nervous embarrassment.

A screenshot of an AO3 fanfiction called The lesser of two evils by SeraphStarshine. The summary is as follows: There is a second option," Dimitri says, voice gentle. "A way I can save you." "What are you talking about?" Sylvain tries not to feel the warmth of hope filling his chest. "It is…not ideal. But you will be safe, here, with me." "With…you?" Sylvain winces as Dimitri trails his fingers down his neck, pressing at his sensitive scent gland. Sylvain has hidden his alpha nature his entire life, but when his secret is finally revealed, he is sentenced to death for being a potential threat to the throne. He isn't ready to die—not yet—but is the alternative any better?

Omega Sylvain Weekend is almost upon us, time to share some of my past entries 🫡

Setvain | #OmegaSylvain26
Sylvain is bracing for a spanking from Seteth, palms flat on the table. Seteth's got one hand planted on the small his back, keeping Sylvain in position. There's a long ruler in his other hand. Sylvain's trying to look at Seteth over his shoulder, flushed and eyes welling up with tears. More sketches: The spanking has triggered Sylvain's heat. There's a wet patch forming between his legs. Seteth says "Tch, of course. Such insolence." as he palms Sylvain's crotch gingerly. The heady embarrassment has Sylvain hiding his face in the crook of his arm, stuttering out a quiet curse.

sharp at both ends by desmodus summary: "An arrangement, huh," Sylvain says. Nausea climbs up his throat to lie thick on the back of his tongue. A letter might've been nice. Just to let him know he was up for bid. Maybe he would've gussied himself up a little. ー Felix offers Sylvain a solution to the problem of arranged marriage. Sylvain doesn't think much of his methods.

Fic title “let it be enough” by Weeniewife. Summary says “stress from a recent accident brought sylvain into an early heat. Felix is the only one there, and they already swore not to go all the way if it ever happened like this again. Felix looks for a loophole to help him out AND keep their promise. Sort of.”

happy #OmegaSylvain26 weekend!

sending a pheromone bomb into battle is time-honored tactic 😜💦 #superart #fanart
digital illustration of sylvain from fire emblem 3 houses. he is academy era, in a modified, slutty version of the dancer class. his chest is exposed and he is pulling aside his skirt to reveal he isn't wearing anything - not even panties! we can clearly see his naked pussy, dripping profusely. his expression is set in a grimace- he was not expecting his heat. everyone on the battlefield will want a piece of him.

Plan B yuripunch Summary: "Aren't you even a little curious?" Sylvain's mouth parts in sync with an almost imperceptible, viscous sound. His hips jostle under the thin sheets covering him. Jeritza scowls and he slams the book shut. "For a grown man who cannot control his own heats?" Jeritza scoffs. The other man squirms under his heated glare. With their eyes fixed on each other, Jeritza approaches him and yanks the sheet off of him. Sylvain's panties are carelessly bunched up beside him. "Shameless," Jeritza mutters.

Drop Dead by yuripunch Summary: "Any other secrets I should know about?" Felix presses. He tries to plop Sylvain onto his bed when they get inside the house, but Sylvain clings to Felix's shirt. "I want this," Sylvain pleads. He tugs on Felix's shirt again. Felix grows hot. How is he supposed to interpret this? Is Sylvain that delirious? Admittedly, Felix knows next to nothing about omegas. He sat through secondary-sex education when he was 11 like everyone else, but he was too busy playing with a damn Tech Deck to listen! He curses his past foolishness.

Just a quick little silly drawing for #omegasylvain26 because goddamn, teaching makes me tired. But enjoy sylvain sweating his hairy little ass off while hilda reclines and cracks the whip.
Sylvain Gautier sweatily bounces on Hilda Goneril's fist/dick (you decide) while an embarrassing amount of slick coats his inner thighs. His mouth is open comically wide, and I'm sure we can all imagine the sounds being torn from his throat. Hilda has her hand raised, about to smack his pert little ass, and Sylvain is gripping his thighs as though his life depends on it.
