100x Rebate Sharing System: Retired Incubus Wants to Marry & Have Kids

Chapter 10: Chapter 10 - First Evidence of Incubus Bloodline

Helena’s mouth felt like a warm, wet suction around him—sloppy and tight, her saliva pooling hot against his skin.

The way her tongue finally stirred, barely flicking at the underside of his shaft because it was so crammed in there, sent jolts up his spine.

It wasn’t perfect; her teeth grazed him awkwardly now and then, and the musky tang of his own sweat mixed with her spit made it all feel dirty.

”Nanny, yes... it’s so warm inside you,” Viktor muttered, his voice thick as he rocked his hips shallowly.

He’d never done this before—not in his past life buried in books, not even jerking off because who had time between studies and noble bullshit.

This was his first everything, and it hit like a dam breaking. The pressure built fast in his balls, heavy and insistent, making his thighs quake.

Even through her tears—streams cutting tracks down her flushed cheeks—she heard the pleasure in his groan, the way he said her old nickname like it meant something tender.

It twisted in her gut, but her eyes squeezed shut, and she tried harder, tongue pressing flat against that veiny underside, lapping sloppily at the salty skin she could reach.

He trembled, breath hitching. ”Nanny... yeah, like that...” His hands fisted her hair tighter, yanking her forward until her nose mashed into his pubic bush, the coarse hairs scratching her skin.

His cock shoved deeper, the bulbous head bullying past her gag reflex, stretching her throat until it bulged visibly—a thick outline pressing out her neck, right under her chin like an obscene knot.

”Guhk—!” She choked around it, but he didn’t let up.

”I’m cumming!” Viktor groaned, body locking as his first load in this world erupted—ropes of thick, pent-up cum blasting straight down her throat.

It was messy, endless, years of nothing flooding out in bitter, sticky bursts that overflowed her mouth despite her swallows.

The taste was sharp, almost acrid, coating her tongue like glue.

Helena gagged hard—”Khwaak!”—yanking back as he finally released her hair.

She pulled off with a wet pop, coughing violently, strings of spit and semen dangling from her swollen lips.

Cum dribbled down her chin, mixing with tears as she gasped for air on her knees, chest heaving.

Viktor stumbled back, legs weak, and collapsed onto the dusty sofa, his pants still tangled at his ankles.

His cock flopped out, spent and glistening, a few last drops beading at the slit.

He blinked down at her—face a wreck of red skin, watery eyes, cum-smeared mouth—and guilt hit him like cold water. ”Hey, are you alright?”

She coughed again, wiping her mouth with the back of her hand, but more spilled out. ”C-cough... y-yes, young master... I... cough...”

”Oh, hold on.” He scrambled up, yanking his pants halfway to his knees as he lunged for her bag. Rummaging through the neatly packed supplies, he found the water pouch—leather, half-full—and thrust it at her. ”Drink. You’re choking.”

Helena grabbed it with shaky hands, gulping desperately.

Water spilled over her chin, trailing down her neck and between her heavy breasts, mixing with the sticky remnants of his load.

In the moonlight filtering through cracked windows, her thick body looked even more inviting—curves glistening, thighs pressed together as she knelt there, skirt hiked up enough to show the dark patch on her panties.

Viktor’s eyes lingered, heat stirring again. His cock, half-limp and slick, twitched and started hardening once more.

’...Even with small size, at least I got vitality.’

Gulp gulp.

’Urgh... I-I will die—’ Helena’s thoughts spiraled as she gulped the water, her throat still burning from the stretch and the taste—god, that taste. Bitter, thick, like swallowing something gone bad.

Her tongue felt coated, no matter how much she drank.

’I can’t... I can’t do that again...’

The burn lingered deep in her throat, making her wince with each swallow. She wanted to tell him to stop, that it was too much, that she wasn’t built for this kind of thing.

Her hand trembled as she lowered the pouch, wiping her mouth again.

But then she lifted her head.

Viktor sat there on the dusty sofa, chest heaving, pants tangled around his ankles. His soft belly rose and fell with each breath, and his expression—flushed, eyes half-lidded, lips parted—showed pure, unfiltered satisfaction.

He looked like he’d found something precious in this hellhole of a manor.

And then her gaze dropped lower.

Her eyes widened.

His cock stood again—fully erect, jutting up from between his thick thighs like it hadn’t just emptied down her throat moments ago.

The foreskin had pulled back completely now, stretched taut over the swollen head that glistened dark pink in the moonlight.

The skin looked ready to tear from how engorged he was, veins bulging along the shaft like twisted roots. His heavy balls hung below, still looking painfully full.

To her, it looked monstrous.

To him, resting back with his belly obscuring most of the view, he could only see those four inches past his stomach—unaware of the beast below.

”Helena...” His voice came soft, almost shy. ”Can you suck it again?”

She trembled, eyes blinking rapidly as the request hit her. Her throat still ached, her jaw felt sore, and the memory of that awful taste made her stomach turn.

’No... please, I can’t...’

But then she saw his face again—that genuine pleasure, the way he looked at her like she’d given him something no one else could.

The young master she’d raised, who’d never asked for anything selfish until now, sitting in this rotting manor with nothing but her.

She nodded, swallowing hard.

”Y-yes, young master...”

Her knees scraped against the dusty floor as she shuffled toward him, feeling strange and dirty but unable to refuse him.

This wasn’t how she imagined serving him would be, but seeing him enjoy it made her chest tighten with something she couldn’t name.

She arrived before him, kneeling between his spread legs.

Both hands reached out, fingers barely wrapping around his girth—her fingertips couldn’t even touch when she gripped him. The heat of it pulsed against her palms.

Helena parted her lips, leaning forward—

”Wait.”

His hand landed on her head, stopping her. She looked up, confused.

”I forgot to ask...” He scratched his chin, averting his face before forcing himself to look at her. ”How does it taste?”

”W-what?” Helena blinked.

”I mean...” Viktor’s voice dropped. ”Can you tell me how it tastes? My... you know.”

Her mouth trembled as she glanced between his face and his cock. Her fingers squeezed unconsciously around his shaft.

”I-it was... s-strange... good. It was g-good, young master.”

But her stammer gave her away. Viktor’s expression fell.

”Was it bad?”

She averted her gaze, biting her lip. The words came out barely a whisper.

”I... I didn’t like it.”

The admission hung in the air like a death sentence. Viktor felt something pierce his chest—sharp and humiliating. His shoulders sagged.

’Fuck.’

All those porn videos he’d watched in his past world, all those exaggerated moans and eager faces—none of it prepared him for reality. He’d messed up. Completely.

To be honest, he knew those were just fictions and had hardly any relation with reality. But for some things like erogenous zones of a woman, knowing techniques and positions from the porn, he thought at least there would be some small reality. But it seemed he needed real experience.

’Fucking whoever sent me to this world. Not only did you give me a five-inch dick, but you made my cum taste like shit too.’

The bitterness ate at him, but something else nagged harder.

Helena hadn’t complained. Even now, after admitting she hated it, she’d still come forward to do it again when he asked. No hesitation beyond her physical discomfort.

’She’s really... meant for me, isn’t she?’

That realization twisted his gut. She’d go this far for him.

Viktor inhaled deeply, closing his eyes. When he opened them, his voice came out steadier.

”Leave that. Come sit beside me.”

Helena trembled, slowly standing on shaky legs. She looked at him with worry etched across her flushed face as he fell into deep thought, staring at nothing.

’The 100x herbal ability... that could solve hygiene, taste, contraceptive issues... but what about size?’

His mind raced.

The system he’d unlocked—gaining abilities through sex—meant Helena’s herbal knowledge would amplify a hundredfold once he finished with her.

He could use that to handle his weight, create potions for stamina, fix the awful taste issue, prevent pregnancy until he was ready...

But his dick size? That was permanent hardware.

’How the fuck do I increase that?’

He sulked internally, chuckling darkly as he leaned forward, grabbing his belly and trying to pull it up to look down at his cock.

But he couldn’t bend that far. Giving up, he turned to Helena instead.

”Do you have a measuring tape?”

She blinked, clearly thrown by the random question, but nodded quickly. Seeing him this troubled made her want to help.

”Y-yes, yes, young master. I brought one.”

She hurried to the bag, rummaging through the organized chaos until she pulled out a cloth measuring tape.

Returning to him, she held it uncertainly.

”Can you measure my dick?” Viktor’s voice came flat, resigned. ”Even if it’s 5.2 or 5.3 inches, I just need to know. Just measure it.”

Helena’s face flushed crimson, eyes wide.

”C-come on, Helena. Just tell me the truth. How small is this thing?”

Her hands trembled as she knelt again, unrolling the tape.

She bit her lip, fingers shaking as she pressed one end against the base of his cock where it met his pubic bone—pushing through the hair to get accurate—and stretched the tape along the top of his shaft to the swollen tip.

Her eyes traced the numbers, widening further with each inch.

She swallowed hard, face burning as she muttered the result.

”S-seven... seven point eight inches... young master...”
