Sex in C Major
Chapter 100

It was hard enough that a cisgender man would have cried. And yet Stefan felt the full-body shudder that ran up Yannis' spine as sure as if it had been his own. And when Stefan rubbed his fingers hard against the base of his dick, it happened again. And again.

Stefan gazed in silent awe as Yannis stretched out in the seat, head back and knees wide, and rolled his hips up in long, idle motions. He rubbed against Stefan's hand without a shred of self-consciousness, and even began to rub a hand against his nipples like he was simply masturbating. Like Stefan was his own hand, jacking himself off to a scenario in his head.

Stefan swallowed, throat suddenly dry, and glanced down.

Yannis was aroused. But his cock was soft and dry.

And finally, the obvious clicked.

Whatever surgery Yannis had had, it hadn't given him the ability to get hard.

He could enjoy sex all he wanted, but he couldn't get an erection. And Stefan knew he'd had one, because he'd felt it. Yannis had fucked him like a machine before, so-

He glanced at the abandoned lube bottle and condom.

Which was not, on examination, a condom at all. It was a small, slim sleeve, with a flexible rod.

It slipped over Yannis' dick like a foot into a sock. Form-fitting and simple. Stefan moved delicately, and had to swallow against the sudden watering in his mouth as the soft cock was transformed in seconds into a hard erection that lay heavy in his palm, jutting out from its owner's body and demanding to be appeased.

It looked-

Natural. It looked entirely natural. The rod blended into Yannis' skin harmoniously; the material was see through, giving the slightest appearance of a condom rather than anything else. If Yannis had simply walked back into the living room wearing it, Stefan would never have known.

So he touched, stroking the soft material and the steely length within, and kept rubbing at the hidden secret spot at the base of Yannis' dick until he appeared to climax with a shudder and a deep, guttural groan, shaking in a silent, almost invisible ending that Stefan recognised only all too well. Did Yannis still orgasm from the inside, like Stefan did? Did he feel that ripple of muscle so powerful and intense that it was horrifying and heavenly all at once? Did he feel anything in his cock and balls at all, or were they simple additions in that moment, where everything came right back down to a white-down in the mind and a burning in the nerves?

"Get up there, then."

His master's voice was a shock, and Stefan jumped.

"You think jacking him off means your job is over? He deserves a bit more attention than that, don't you think? Why don't you put on a show for him?"

"Y-yes, Sir."

Stefan stripped off his boxers and straddled Yannis' thighs, massaging the hard dick in the palm of his hand. He'd never done this before. And yet he could feel his master's eyes on his back, and Yannis was simply watching him without the slightest hint of helping...

Stefan reached for the lube bottle. It was a blue one, a type he'd not been given before, but it was thick and slick in his hand, and gleamed wetly on the shaft as he smoothed it over Yannis' dick. Yannis sat and watched, an arm slung along the back of the sofa. He looked arrogant. Disinterested. A master simply waiting for a slave to do its job.

Stefan took a deep breath, lifted himself onto his knees, and pressed down.

For a split second, as the sheathed head breached him, slick and hot, Stefan's entire body yearned for more.

Then it hurt.

It hurt.

The motion of lowering himself into Yannis' lap was making him clench. Making him tight. Making him squeeze around the invading cock until it was like the first time all over again. And when he stopped, gulping for the air that had been driven from his lungs, his master's hands came down on his hips and shoved him the rest of the way.

"Oh!"

It was a fist. It punched its way through his resistance. A single strike, brutal and bruising. He scrabbled blindly for Yannis' shoulders to steady himself. His thighs shook, and his legs felt weak and numb. When his master's hands vanished, there was nothing but cold air, and the hot dick burning inside of him.

And a buzz.

A tingling sensation, almost vibrating over Yannis' cock. It burned and hummed against Stefan's flesh. It was hot and cold all at once; it felt like his skin was shivering and clenching at the same time.

And it felt-

"Fuck," he whispered. "Fuck, fuck, that-that-"

A hand came to rub over Stefan's dick. It smeared a thick layer of slickness over his skin, and the burning, tingling feeling erupted there, too. Stefan whimpered, screwing his eyes closed, and drank in the sensation.
