Castien lifted him and shoved him onto his desk.
It was a matter of moments to pull Eridan’s pants off and open Castien’s fly.
Eridan moaned, looking at the ceiling dazedly as his Master pushed into him in one hard thrust. He was so slick already he was dripping, his body hungrily adjusting even to his Master’s considerable girth. Fuck, he’d never get enough of this: feeling a part of his Master’s body inside his own, thick and pulsing, having proof that his Master wanted him. It was intoxicating.
His hands gripping Eridan’s hips, Castien pulled out, leaving only the head inside, and slammed back in. Eridan whined, tightening his legs around his Master’s muscular middle.
Part of him, a distant part, wondered if Irrene could hear them. He wasn’t even sure he cared; not at this moment. All he could feel was need: need for this horrible, heartless man, the need he shouldn’t have felt but did.
He gripped the edge of the desk and held on as the older man on top of him gave him a brutal fucking, all base, animal instinct and telepathic marks twining hungrily. It was unbearable. Unbearably good. Eridan hadn’t thought it was possible to feel so good, the pleasure spreading from his crotch to the rest of his body, sending his hunger spiraling higher and higher until all he wanted was more, harder, deeper.
He might have said that, but he wasn’t sure. He was too busy moaning and making unintelligible sounds, the cock in him driving away all rational thoughts. At that moment, all those demeaning slurs people said about throwbacks were true: he felt like a whore, like he would die without that cock in him, without his Master’s come inside him.
It was strange how much the thought turned him on. There was something incredibly satisfying about the thought of his Master’s bodily fluids inside him. He suddenly needed it, craved it, craved with the strength of three years of desperate longing, his hole gushing with slick, his cock leaking profusely as the thick cock inside him pounded him into the desk.
“You are dripping all over the desk,” Castien gritted out. “Do you know how old it is?”
“Very?” Eridan guessed, moaning as Castien hit the spot inside him just right. “Ah! There!”
His Master glared at him, his grip on Eridan’s thighs tightening, his eyes feverish as his cock thrust into him at a punishing pace, hitting that spot with cruel accuracy. Eridan completely lost it, whines and groans slipping out of his mouth with every thrust of that cock, their bond full of pleasure and burning need.
“Come in me, come in me, come in me,” he heard himself murmur deliriously. “Come in me, Master.”
Those words seemed to snap something in Castien, a low growl leaving his throat, his jaw tightening as he slammed his cock inside him, once, twice—and came, spilling deep into him. Eridan groaned, his Master’s pleasure triggering his own, his hole clamping down like a vise around Castien’s shaft and milking it of every drop of his semen as his own cock spurted between their bodies, dirtying up his Master’s impeccable clothes.
Eridan sagged against the desk, his body and mind tingling with pleasure. Fucking hell. He’d never felt so satisfied in his life. So fulfilled.
After a while, he felt Castien straighten up.
Then he heard the sound of a zipper.
He still didn’t open his eyes. Couldn’t. He felt too good. He didn’t want to ruin it.
“Eridan.”
“Mm?”
“Eridan, get up and fix your clothes.”
Eridan didn’t move.
A sigh.
Then he felt wet tissues between his legs, wiping the bodily fluids. Surprisingly gentle hands pulled his pants up and fixed his fly.
“Get up. You cannot lie on my desk all day.”
Reluctantly, Eridan forced his eyes open.
His Master’s cool gaze was the first thing he saw.
“It is useless to pretend that this is never going to happen again,” Castien said, his expression slightly pinched. “It likely will. But I want to make it clear that this does not change anything. You are my apprentice. I am your Master. That is all.”
Eridan nodded.
“I expect you to behave like a good apprentice would. Do not presume that our… extracurricular activities will make me lenient. They will not.”
Eridan nodded again.
Castien’s eyes narrowed. “Are you even listening to me?”
“Yes, Master,” Eridan said. “This means nothing. Nothing will change. Got it.”
Castien gave him a look full of suspicion. “Now go back to High Hronthar. I have an appointment soon.”
Eridan hopped off the desk but had to steady himself as his legs felt unexpectedly shaky and he had aches in interesting places.
He looked at his Master and quashed the urge to kiss him goodbye: that definitely would contradict the “nothing will change” policy Castien had just outlined.
“Will you be coming home tonight?” Eridan said as he laid his hand on the door handle.
After a moment, Castien said, “Yes.”
