Filthy [ The Lesson ]

 

Chapter 4

The Lesson

 

 

Belgrade, Serbia.

Six years ago.

 

 

Miloš unbuckled his belt with hands that still held the faint tremor of tonight’s work.

Although he knew his son had showered, the shower hadn't reached everything. His knuckles still carried the faint yellow-brown of blood that had dried and been scrubbed but not fully surrendered, and a few nails were still edged black. Miloš had clawed into a dying man's throat tonight and ripped.

The evidence was right there in the half-moons of his fingers.

Lazar grinned.

Miloš continued.

The leather belt slid through the loops in a hiss that came out louder than it should have in the quiet room, like a zipper being drawn on a body bag.

Soon, he popped the button and shoved the jeans open.

There were no underwear.

Of course not.

Lazar snorted low in his throat.

Like father, like son.

“Thank you for this, Tata.” Miloš reached inside and dragged his big cock out—thick, heavy, already brutally rigid.

Lazar parted his lips.

The shaft bobbed free, slapping once against Miloš’s lower sculpted abs with a soft, wet thwack before standing proud between them.

The head was flushed an angry rose-purple, swollen and glossy, the slit already weeping. A thick bead of pre-cum welled up immediately, then another, stringing down the underside in slow, obscene threads that caught the blue-white glow from the laptop and shimmered like liquid silver.

Lazar went utterly still. His breath snagged somewhere between lungs and throat, refusing to move.

Well. . .there it is.

His son’s cock was his—almost a mirror image. Same heavy girth, same prominent veins snaking under olive skin, same slight leftward curve when fully engorged.

But Miloš’s was younger, smoother, untouched by a piercing, the head still glossy and unscarred where Lazar’s had been pierced years ago.

Pre-cum continued to drool from the slit in lazy pulses, coating the crown until it shone wetly, a single strand stretching and breaking to drip onto the denim still bunched around Miloš’s thighs.

The scent hit a second later—sharp, musky, overlaid with the faint copper tang of blood and gun oil that still clung to his son’s skin.

Pride slammed through Lazar’s chest, hot and liquid like the last swallow of rakija.

Same blood. Same filthy inheritance.

His own cock gave a traitorous twitch.

Miloš looked at his father’s cock.

Lazar’s pierced head nudged forward as another bead of pre-cum welled at his slit and slid down the gold serpents.

The room felt too small.

Too warm.

Too full of their shared scent.

Lazar looked up at Miloš. “You said it didn’t drip like mine, but it is dripping now.”

“I’m ready.”

“You surely are.” Lazar cleared his throat and looked at Dayo.

She had pushed herself up on the white sheets, no longer content to lie passive on her side. She sat forward now, knees drawn up and spread wide.

The camera caught every inch of her—deep brown skin glistening with a fresh sheen of sweat, long braids spilling over her shoulders like dark rivers, full breasts swaying heavily with each quick breath.

Her hands were already on her body.

She cupped both breasts, lifting them toward the lens as if offering them directly to the two men on the other side of the screen.

Miloš groaned.

Lazar’s smile widened. “You like that, son?”

“Yes. Where did you find her?”

“Never mind that part. What do you like most of all?”

“I cannot pick just one thing. I want to devour her.”

Dayo smirked. “And I would love for you to eat me up too, sweetheart.”

Lazar looked at his son. “Grip your cock.”

Miloš ignored him or hadn’t heard the instruction. He was too busy watching Dayo as her thumbs began to circle the dark, pebbled nipples slowly at first—teasing—then pinched harder, rolling the stiff peaks between her fingers until they lengthened and darkened even more.

A low, throaty moan rolled out of her, vibrating through the speakers and straight into the quiet Belgrade office.

A little bit of drool left Miloš’s lips.

Lazar frowned. “Miloš!”

His son blinked and looked at him. “Yes, Tata?”

“Wipe your damn mouth and grip your cock.”

Dayo laughed.

Lazar turned to her. “Behave. I’m trying to give him a lesson.”

“How can I behave? God, look at you two.” She moaned again. “Father and son with matching cocks leaking. So fucking beautiful.”

She tugged one nipple sharply, making her breast bounce, then switched to the other—pinching and twisting until her head tipped back on a gasp.

Mmm.

"That's right, daddy.” Dayo purred. “Show your boy how to play with that young cock."

Lazar shivered. “Dayo.”

“What? I can’t be as filthy as you?” She licked her lips and dropped one finger to tease her clit.

“Be a good girl.”

“But I want to be so bad.” She laughed breathlessly and her gaze locked on their leaking tips. "Look at those matching cocks, dripping. . .I want to lap it up, suck the cum right off daddy's serpents while baby boy fucks my ass raw."

With those words, Lazar forgot all about the lesson as his fingers wrapped around his thick shaft. The gold serpent piercings twisted as his foreskin slid back.

God yes.

His hips rocked forward involuntarily, cock pulsing hot against his palm as another pearl of pre-cum welled at the tip and glazed over the piercing.

“Your cock is so big, Tata.” Miloš leaned forward until he was very close to Lazar. His gaze dropped to Lazar’s hand as Lazar continued to stroke his length.

“Wow.” Those pupils dilated as he further leaned forward, transfixed by the sight of his father's veined length disappearing into his fist with each slippery stroke, the piercing emerging slick and glistening on every upstroke.

Lazar felt his son's eyes like a physical touch and caught himself mid-groan.

Fuck! That’s right. The lesson.

He cleared his throat, stopped himself, and loosened. "Miloš, pick up that glass bottle and put the liquid on your cock."

“How will it feel?”

“You will see.”

“Will my cock like it?”

“I guarantee it.”

Miloš grinned and did as his father instructed him.

The lube came out and landed across the thick crown.

Miloš’s breath changed on first contact.

The warmth was immediate, spreading through the shaft in a low rolling wave that had no edge or peak. It was continuous and deepening.

Miloš groaned. “Fuck. This does feel good.”

“Spread it over your cock, son.”

He did that too, moving one slow stroke from base to crown. “Oh, Tata. I like this so much.”

His head dropped back against the leather and a sound came out of him that he didn't try to suppress—low, open, and completely undone.

The whole length of Miloš was gleaming now, the pre-cum mixing with the warming lube. It was all slicker and more obscene.

Lazar smirked. “Dayo, doesn’t my son have a nice cock?”

“Oh, yes.” She licked her lips. “If I was there, I would suck on it while you fucked me from behind.”

Miloš groaned. “Let’s do that. Where is she?”

“I’m—”

“Too far to do that now.” Lazar interrupted Dayo before she could provide too much information.

She pouted, but was smart enough to know not to push it.

Miloš lifted his head and slowly rubbed his cock up.

That was when Lazar noticed the problem. “No. Really touch your cock.”

Miloš looked down at it and tightened his grip. “Like this?”

“No. What are you trying to do? Choke it to death?”

“Yes. I want to choke it really bad, Tata. And have her choke it too.”

Dayo laughed.

Lazar raised his hand off his cock. “Alright. Calm down. Look. Your grip is wrong.”

“Show me.”

“I’m trying to tell you—”

“Show me, Tata.”

Lazar groaned in annoyance, but there was no real anger in it. “Fine. I will show you.”

“Yes.” Dayo laid back down on the bed. “Show him, Daddy.”

Lazar shook his head, reached for the glass bottle, uncapped it with his thumb, and poured a thick, generous drop of the warming lube directly into his palm. The clear gel pooled there, cool at first, then already starting to bloom with that insidious heat as it sat against his skin.

Lazar turned to his son. “Move your hand.”

Miloš obeyed instantly—his fingers loosening and sliding away from his own shaft. The cock bobbed free again, slick and shining, pre-cum still mixing with the lube he’d half-spread, strings of it stretching between his palm and the glistening head like obscene spider silk.

“The things I do for love.” Lazar leaned forward, closed the last few inches of space between them, and wrapped his big, scarred hand around the base of his son’s cock.

The contact was electric.

“Oh, fuck, Tata.” Miloš sucked in a sharp breath. His hips jerked forward on pure instinct before he caught himself.

“Calm down.”

Miloš’s eyes went wide, pupils swallowing the irises, and then fluttered half-shut as Lazar’s grip tightened—not punishing, but firm, possessive, and teaching.

“Like this,” Lazar whispered.

“T-tata. . .it feels so good.”

“Yes, but don’t focus on how my hand feels on your cock. Focus on the grip.” Lazar slid his palm up Miloš’s cock in one slow, sensual stroke, twisting slightly at the crown the way he always did on himself, letting the warming lube do its work.

“Oh God.” Miloš trembled. “This is heaven.”

“But are you focused on the grip?”

“Yes, Tata.” His breathing shifted to panting. “Show me more.”

The gel heated instantly against the sensitive skin, spreading fire along every vein, every ridge. Pre-cum welled fresh at the slit and smeared under Lazar’s thumb as he circled the head once, twice—coating it, polishing it—before dragging back down to the root.

Miloš gripped the arms of the chair hard and let out a broken, shuddering moan. His thighs trembled. The sculpted muscles stacked on his stomach clenched hard, carving shadows. His head tipped back against the leather chair, throat working. “Fuck. . .Tata. . .that’s… that’s so much better.”

“You were gripping your cock too tight and being mean. Holding it like a gun and trying to shoot.” Lazar kept the rhythm steady—long, firm pulls from base to tip, foreskin gliding smoothly over the swollen head.

The gold serpents on his own cock twitched.

He could feel his son’s pulse hammering against his palm, thick and frantic, the shaft thickening even more under his grip.

“You must loosen your fist a little.” Lazar eased the pressure just enough to let the skin slide instead of drag. “Feel it build. Don’t choke it. Let it breathe. Let it beg.”

“Fuck yes, Tata.” Miloš’s hips rocked up into his father’s hand in tiny, helpless thrusts. “But. . .please. . .don’t stop.”

Lazar grinned. “I must stop—”

“No.”

“Are you even paying attention?”

“Yes. I’ll show you.” Miloš’s hand moved without hesitation—large, warm, still faintly stained at the knuckles—wrapping around the thick base of Lazar’s cock.

What?

Lazar’s breath punched out of him in an involuntary grunt.

Fuckkk.

The gold serpents shifted under his palm as he gripped, tentative at first, then firmer, mimicking the slow, twisting stroke Lazar had just shown him.

The sensation was immediate and obscene. His son’s callused fingers sliding over slick skin, the warming lube making every glide molten, the faint roughness of those blood-edged nails grazing the underside of his shaft in a way that should have felt wrong but instead sent fire straight to his balls.

Miloš’s grip was strong—stronger than Lazar had expected from someone so new to this—and the way he twisted at the crown, just like Lazar had demonstrated, dragged a thick rope of pre-cum out of the pierced slit and smeared it down the length.

The boy learns fast.

Lazar’s hips jerked once, betraying him.

He told himself this was still the lesson.

Control.

Technique.

Release.

Nothing more.

On the screen, Dayo had gone feral. “Oh my God.”

Still stroking his son’s cock, Lazar turned to her, thinking he could gain some clarity.

But, she was on her knees now, thighs spread obscenely wide, one hand still caressing her breast—pinching and twisting the nipple until it stood out dark and angry—while the other plunged three fingers deep into her soaked pussy.

The wet, rhythmic squelch of her hand fucking herself filled the speakers, loud and shameless.

Lazar gritted his teeth.

This is fine. This is mathematics.

“How am I doing, Tata?”

Lazar turned to his son.

Lust glazed his boy’s eyes. “Do you like how I’m stroking your cock?”

“Yes, son.” He licked his lips. “Like that. You’re such a good boy. Doing it just how I like it.”

“It’s so thick, Tata. I can feel your pulse.”

This is just a lesson. That’s it.

Lazar stroked his son some more, triggering a gasp.

And Miloš answered back by using his thumb to circle Lazar’s flared head and brushing over the gold bar and the tiny serpent fangs.

“Good grip.” Lazar swallowed hard. “Keep going.”

He tightened his own fist around Miloš’s cock in response—matching the rhythm now, father and son stroking each other in perfect, mirrored sync.

Long pulls from root to tip.

Twists at the crown.

Thumbs over slits.

More pre-cum spilling from both.

The room filled with wet, slippery sounds—skin on skin, lube squelching, ragged breathing, the faint metallic clink of Lazar’s piercing dragging across Miloš’s palm every few strokes.

On the screen, Dayo was unraveling.

She’d shifted to all fours, ass toward the camera, thighs trembling as she fucked herself with four fingers now—deep, punishing thrusts that made her breasts swing heavily beneath her. Her free hand reached back, spreading herself open so they could see everything—the slick, swollen lips, the way her pussy clenched and fluttered around her fingers, the crystal dildo discarded but still glistening beside her hip.

“Look at you two.” Her voice was wrecked. “Father and son. . .jerking each other off. . .matching cocks leaking. . .fuck, I’m going to cum so hard watching this.”

Her hips snapped forward, fingers slamming in and out, thumb grinding her clit in frantic circles.

Her moans turned into sharp, desperate cries.

Miloš’s stroke faltered for a second, and his own cock jerked violently in Lazar’s hand. “Where is she?”

“Focus, son.”

“I want her here. Now.”

“No. Just be happy with this,” Lazar ordered, even as his own hips rocked into his son’s fist. “Watch how she falls apart. That’s what you’re working toward.”

Dayo’s back arched, thighs shaking.

Her whole body seized.

A gush of wetness coated her fingers, dripping down her wrist as her pussy pulsed visibly around them.

She screamed—raw, broken, beautiful—head thrown back, braids whipping.

The sight snapped something in both of them.

Miloš groaned, deep and guttural, his hand speeding up on Lazar’s cock—tight, slick, relentless. “Tata. . .”

“Let go, son,” Lazar growled, matching the pace, fist flying now over Miloš’s shaft. “Cum.”

“Oh.” Miloš’s hips bucked hard into Lazar’s grip.

“Yes. Right there.” Lazar watched his son's face through every second of it. “Good boy.”

Miloš’s jaw locked. The throat working. The eyes pressed shut with the specific expression of a body finally given permission to speak a language it had been carrying alone for years.

Good. Now you’re truly learning the joy of life.

Pride moved through him wider than anything he had a name for.

“Tata!” Miloš's cock swelled impossibly thicker in Lazar’s hand, veins standing out, then erupted.

One spurt of cum landed on Lazar's wrist. Lazar felt it before he saw it—the heat of it, the weight, the specific intimacy of being marked by his own son's body in the most unmistakable way possible.

He looked down at his wrist.

Same blood. Same cum.

He did not wipe it off.

Then his son's grip tightened and the thought dissolved completely because the sight—his son coming undone in his hand—pushed Lazar over.

He came with a low, choked roar, hips snapping forward into Miloš’s fist.

His pierced cock pulsed violently, thick jets of cum shooting out in heavy arcs, painting his own stomach and dripping down the gold serpents. Each spurt dragged a groan from deep in his chest, pleasure so intense it bordered on pain.

They kept stroking each other through it—slowing only when the sensitivity became too much, milking the last weak pulses until both cocks were spent, slick, and twitching in the cooling lube and cum.

For a long moment, no one spoke.

Just heavy breathing, the wet shine of skin, the faint scent of sex, brandy, blood, and gun oil hanging thick in the air.

Dayo collapsed forward onto the sheets, still trembling, fingers glistening as she brought them to her mouth and licked them clean—eyes never leaving the screen. “Jesus, that was. . .the most beautiful thing I’ve ever seen.”

Lazar finally released his son’s cock.

Miloš did the same.

They sat there, spent, chests rising and falling in tandem, the blue-white glow from the laptop washing over both of them like shared sin.

Lazar looked at his son—flushed, trembling, cum-streaked, eyes still wide with awe.

Then he looked at Dayo—smiling, sated, waiting.

Finally. . .Lazar looked at his wrist and studied the cum with complete stillness.

It was thick.

Pearlescent.

Cooling slowly against his pulse point, where the skin was thinnest and the radial vein ran closest to the surface.

Lazar could feel his son’s cum with each beat of his heart too.

And there was a warmth spreading over him that had nothing to do with the lube.

His son had spilled across the exact place where a man's life could be measured in beats per minute, and the irony of that was not lost on him either.

He brought his wrist closer and looked at the physical evidence of what this room had witnessed tonight, transferred from his son's body to his own in the most direct language available to men who did not otherwise speak about what they felt.

He had put his hands on his son tonight.

His son had marked him in return.

Equal exchange. That's what that is. Nothing more.

Lazar lowered his hand, but still did not wipe the cum away.

When he checked his son again, it occurred to him that Miloš had not wiped his hand either. His son's palm still carried traces of his cum.

His heart shifted into a twisted, ruined organ inside his chest.

“Lesson over, son.” Lazar cleared his throat. “We don’t do that again, and we damn sure never talk about it. But. . .remember the grip and get yourself warming lube. And. . .a woman just as sexy as my Dayo.”

She grinned. “You can share me.”

“We cannot.” He turned to his son. “Do you understand?”

“Yes, Tata. I do.” But the way Miloš looked at him—soft, grateful, hungry—said otherwise.
