Chapter Text
Diluc came home from college excited. Very excited. He could barely sit through any of his classes; in fact, he rushed through his last lab just to get home on time. Because he knew that, religiously, at 9:00 PM every other night, there was a 75% chance that Kaeya would come wandering downstairs on the hunt for something sweet. Most likely the rest of Crepus’ chocolate cake (the cheeky bastard never even touched his red velvet).
So, what did Kaeya’s occasional sweet tooth have to do with Diluc perversion excitement?
Well, Diluc had finally caved in. Bit the bullet. Bought pills to drug up his little brother so he could fuck him.
Okay, maybe that last part isn’t a saying but you get the point.
So, in advance, Diluc had bought several different desserts and laced them with a powerfully effective sleeping drug. The last thing he wanted was for the kid to wake up while he was balls deep inside of him.
Kaeya would never know that among the powdered buns and delicate cakes there was a predatory plan. Just imagining his naïve expression as he took that first bite was already making Diluc hard.
Uh-oh. Down, dick! Now was not the time! Not yet, at least.
He set the sweets on the table and eyed the clock. 8:57. Shit! He knew he should’ve just skipped that last lab. It was going to be so worth it to fuck into his little brothers sweet, tight cunny. Diluc whistled lowly, swooning at the thought.
“Oh, Kaeya,” he whispered, chuckling darkly to himself. “You have no idea what’s coming to you.” He tried to ignore the shaking in his hands and the doubt in his head as he adjusted an off-kilter macaroon.
As 9:00 rolled around and Kaeya failed to appear, the weight of his actions finally began to dawn on him. Sure, the idealized version of this scenario was hot and heavy in his head, but finally carrying through with it, he just felt…gross. He couldn’t get the image of them playing as toddlers out of his head, or the numerous times they’d play fought and joked around with each other. It was ruining the mood.
It was making him feel….goddamnit, it was making him feel guilty.
I mean sure, yea, he’d cum in his pants while Kaeya was on his lap, but it was an accident! And it was one time. And yea, he’d basically gotten Kaeya to spread his legs for him, but the kid did that willingly. With no interference or coercion from him!
“Fuck,” he sighed, unable to carry through. Diluc stood up and started sweeping the sweets off the table and back into the bag. He was too engrossed in his inner turmoil to hear the soft footsteps approaching from behind.
Soon enough, a small figure appeared, arms crossed defensively.
“Diluc? The fuck are you doing?”
Blue hair blurred his peripheral vision as Kaeya glanced over his shoulder and into the bag.
“Are those…cakes? And sticky buns? And fucking macaroons?”
Quick as a cat, he snatched one of the boxes, stuffing it under his shirt before Diluc could even protest.
“W-wait, Kae, those aren’t meant for – ”
“Tch, what? Were you saving it for some of your college friends?”
The boy obnoxiously giggled, cocking a hip.
“Or are they laced with weed? Honestly, that’s even better.”
“No really, I, I….”
“Oh, please, calm your tits. I’m not gonna tell dad or something.”
The teen rolled his eyes as Diluc mentally shat his pants. Shit. He was probably sweating like the devil’s cock right now. He couldn’t wrestle Kaeya down and grab the box – 1). Because he had a massive boner right now and 2). If he touched Kaeya it would break his new moral chastity rule.
Great. This was a lose-lose situation.
Kaeya shrugged. “Well, if that’s all, I’ll be taking this then.” He began to walk away but turned around, seemingly forgetting to express his gratitude. Slowly, the teen leaned over and whispered sweetly into Diluc’s ear:
“Thank you, big bro.”
And with that, he skipped gayly (no pun intended) up the stairs.
Shit.
How was he supposed to not jerk off to that?
