"Second Aunt… I really feel so uncomfortable," Sam said, his voice strained. He wasn't pretending—his shaft was painfully hard, throbbing like it might burst at any second.
"Calm down first. It should go down soon," Lily replied, her tone laced with worry. She quickly adjusted her clothes, pulling her blouse back into place and smoothing her skirt, silently scolding herself. Why did I tease him like that? Now look what's happened.
She wasn't some shameless woman, but even she couldn't ignore the massive bulge straining against Sam's trousers. Though she hadn't seen it yet, she could tell it was enormous.
He's still just a teenager… but with something that big, he's going to be incredible when he grows up, she thought. Lily was a normal woman with normal desires. With her husband away on overseas missions for years, she had long relied on videos and toys to satisfy herself.
"But it hurts so much…" Sam groaned, his hand moving to the waistband of his trousers. He knew this was his chance. Lily had always rushed to his side whenever he was hurt or sick—she loved him too much to ignore his pain. If he played this right, even her morals might bend.
Seeing the genuine discomfort on his face, Lily's heart clenched. She didn't know what to do at this situation.
Then Sam tugged his trousers and underwear down in one motion.
His thick, rock-hard shaft sprang free, standing tall and proud right in front of her eyes.
Lily's breath caught.
It's huge… bigger than anything I've seen even in those videos. She had watched plenty of porn during her lonely nights—often featuring men with impressive sizes—but this… this was something else entirely.
Sam secretly watched her reaction, and a surge of satisfaction flooding him at the shock and fascination on her face. Pretending to be overwhelmed, he closed his eyes and wrapped his hand around his shaft, slowly stroking himself in front of his aunt.
Lily stared for a long moment, mesmerized by the sight of her nephew masturbating right there in the car. She forced herself to turn her head away, cheeks burning.
But minutes passed, and Sam's expression remained pained. His hand moved only when she glanced over—otherwise, he barely touched himself. Seeing her still looking away, he decided to push further.
"Second Aunt… it's still so uncomfortable. I can't make it go down…"
Lily knew exactly what he meant. He wanted her to help him finish.
This is incest. He's still a child, she told herself. But the words felt hollow.
Suddenly, Sam reached over with his left hand, gently but firmly grasping her right wrist. Before she could react, he guided her palm to his burning-hot shaft.
"Second Aunt, please… help me. I can't do it myself."
The instant her fingers closed around him, Lily's whole body trembled. It had been so long since she'd felt real male heat—and never anything this thick, this powerful.
She took a shaky breath.
"Okay… Second Aunt will help you. But this is only to help you, alright? Just this once. No next time."
Her right hand began to move—slow at first, then more confidently—stroking him from base to tip. She had originally thought of calling her younger sister Anna, the nurse, for advice.
But she didn't.
A part of her wanted to try this herself. If she couldn't handle it, then she'd call Anna. But right now, feeling the massive length pulse in her hand, her long-suppressed female desire stirred awake.
"Is this helping?" she asked softly, trying to sound clinical even as her grip tightened.
"A little more… focus on the top and the bottom. Ohhh… it feels so good. My Second Aunt is jerking me off… Principal Lily is stroking my cock… my goddess…" Sam's words spilled out in excitement, shameless and raw.
Lily's face flushed crimson.
"Sam, you can't say things like that. I'm only doing this to help you."
Yet her hand moved faster, more rhythmically, as if obeying an unspoken command.
Images from the AV videos she watched flashed in her mind—actresses using their mouths on men.
If this doesn't work… will I have to…? No. He's my nephew.
The thought alone made her thighs press together.
She was nervous, excited, conflicted. She could tell from his reactions that Sam harbored improper feelings toward her—teenage boys were always horny, after all.
Thankfully, they were in the underground parking garage. Inside the tinted car, no one could see what was happening.
Lily varied her strokes—squeezing hard at the base, twisting over the sensitive head—trying to push him over the edge quickly.
Her breasts jiggled with the effort, straining against the tight fabric of her dress. She was getting wetter by the second, though her morals desperately fought to hold her back.
Sam saw his opening.
This was the moment to plant the seed. Even if she scolded him later, he could claim it was just excitement talking.
"Second Aunt… I want to fuck you. I want to shove this big shaft in your mouth, your pussy, between your breasts, in your ass…"
The filthy words poured from his innocent, sunny face.
Lily froze, stunned.
This boy… he actually wants to fuck me? His own second aunt? That's too much…
But at the same moment, she felt his cock swell even thicker in her hand.
He was close.
She sped up instinctively, pumping him harder. Her breasts bounced wildly with each stroke.
Sam, sensing the end, delivered his final blow:
"Lily… I want to fuck your pussy. You're the most beautiful woman in the world… I'm going to cum—"
Thick ropes of white semen erupted.
They splattered across Lily's hand, her hair, her chest, and the front of her teacher's suit. A large pool formed on the seat beneath Sam's crotch—thankfully his trousers were already down.
The powerful, musky scent of semen filled the car.
Lily inhaled it involuntarily, her body reacting before her mind could stop it.
Reason snapped back.
She grabbed tissues and frantically wiped the sticky mess from her clothes, her hair, her skin.
Looking at Sam—now slumped back in relief, his spent shaft softening—she couldn't believe what she had just done.
Anger at herself surged…
But beneath it, buried deep, was a faint trace of enjoyment… and something dangerously close to anticipation.
Lily let Sam relax in his seat, his breathing finally steadying as the afterglow settled over him like a heavy blanket. She started the engine with trembling hands, desperate to put distance between them and the underground garage that now felt like a crime scene.
The drive to Champion High School was silent and agonizing. Lily's mind spun in chaotic loops—shock, shame, disbelief, and something darker she refused to name. What the hell did I just do? This was the most insane, most unforgivable thing she had ever done in her life. She kept glancing through side eye, half-expecting to see someone she knew staring back, as if the entire city could somehow sense the sticky residue of semen still faintly clinging to her suit jacket and the faint musky scent lingering in the confined air of the car.
Every red light felt like an accusation. Every passing pedestrian made her flinch. What if someone recognized her? What if they noticed the flush on her cheeks, the way her hands gripped the steering wheel too tightly, or the way Sam sat unusually quiet beside her, staring out the window with a small, satisfied curve to his lips?
She didn't dare speak.
Words would make it real.
When they finally pulled into the faculty parking lot at Champion High, Lily killed the engine and sat frozen for a long moment. Sam hadn't said a single thing the entire ride—just stared ahead like nothing had happened, though she could feel his occasional sideways glances burning against her skin.
She turned to him at last, cheeks flaming. Without meeting his eyes, she reached over and gave his shoulder a quick, awkward pat—more like a mother reassuring a child than the woman who had just jerked him off in her car.
She said nothing.
No goodbye.
No lecture.
No "this never happened."
She simply opened the door, stepped out, and walked away as fast as her heels allowed, clutching her bag to her chest like a shield. Her steps echoed too loudly in the quiet morning lot. She didn't look back—not once.
Behind her, Sam watched her retreating figure through the windshield, the corners of his mouth lifting into a slow, dangerous smile.
Lily disappeared into the school building, heart hammering, mind screaming at her to forget everything.
But deep down, she already knew it was impossible.
The line had been crossed.
And something inside her—something she had buried for years—was already beginning to stir.
Meanwhile, in the car, Sam leaned back against the headrest, still tasting the victory on his tongue.
Phase one complete.
Lily had cracked—just a little.
But a crack was all he needed.
Now the real game could begin.
