After dinner, Nobi Hiroshi sat in front of the TV, watching a popular anime about people with superpowers.
"Why are my hamburger patties so small? Mom is so biased!"
Sprawled out on the tatami, Nobita puffed up his cheeks and pressed his fingers into the mat, glaring at Hiroshi unhappily.
"What can you do about it? It's your fault for failing again," Doraemon said fairly.
"If you could score 100 points like Hiroshi, mom would reward you too."
He held a dorayaki in his round hand, finally able to eat it in peace now that the earlier disgusting incident was out of his mind.
"Sigh… I know, I know. You guys are so annoying," Nobita grumbled. "If I could, I'd get a hundred too.
If only I had superpowers like the people on TV. Everything would be so convenient. I could even get revenge on that hateful Gian."
His eyes suddenly lit up.
"Oh! Doraemon, you must have a gadget that gives people superpowers!"
He turned around eagerly, rubbing his hands together.
"A gadget that gives superpowers?" Doraemon scratched his head and swallowed the last bite of dorayaki.
"There are such gadgets… but Nobita, are you sure you can handle it? The process of gaining superpowers is very difficult. With your lack of perseverance, I doubt you could manage it."
"Don't look down on me! If it's for superpowers, I'll definitely study hard!"
Seeing Nobita's excitement, Doraemon sighed.
"Alright then… Superpower Training Box!"
He pulled out a colorful cylindrical box from his pocket. Several small steel balls rested on top. It looked rather ordinary.
"Nobita, think carefully," Doraemon warned.
"You must train for three hours every day. After three years, you'll be able to master three abilities: clairvoyance, telekinesis, and instant movement."
"Three years?!" Nobita's mind went blank.
Three hours a day for three whole years?
"That's impossible…"
"I told you you couldn't do it," Doraemon said, preparing to put it away. "This gadget is useless to you."
"Wait! I want it! I'll train! I promise I'll persevere!"
Though doubtful about Nobita's usual three-minute enthusiasm, Doraemon reluctantly handed it over.
Nobita hugged the Superpower Training Box and ran upstairs excitedly.
"Doraemon, can I borrow that Superpower Training Box too?" Hiroshi asked calmly.
"Sure. You want to try it as well?" Doraemon replied.
"I'll lend it to you after Nobita gets tired of it. I estimate he won't last more than two days."
Doraemon had already predicted the outcome. Gadgets rarely ended well in Nobita's hands.
"Mm. Thank you."
Hiroshi nodded and continued watching TV, completely unbothered by Nobita getting it first.
Being overly ambitious, Nobita would never endure the training.
Once the gadget returned, Hiroshi planned to use it properly to strengthen himself—especially in preparation for dangerous situations outside everyday life.
The three superpowers sounded impressive, but in the future world, such abilities were already outdated.
There were countless advanced gadgets that surpassed them.
Clairvoyance alone could be replicated by dozens of tools—many with additional features.
As for instant movement, its range was limited and imprecise. Even the earliest version of the Anywhere Door could travel light-years with perfect accuracy.
From a practical standpoint, future citizens wouldn't bother with such a basic training device.
But Hiroshi was different.
He wasn't from the future. He didn't have unlimited access to high-tech gadgets.
Compared to relying on tools, he preferred building his own strength.
If you know martial arts, you aren't helpless.
Gadgets are temporary. If you cannot control them, no matter how powerful they are, they're meaningless.
Good iron must be forged strong.
By 9 p.m., Hiroshi had finished bathing.
He stood before the washstand, examining his reflection. His fair face still carried a trace of childish softness.
"Hiroshi, you must supervise Nobita's studies more at school. Auntie is counting on you."
Tamako stood behind him, gently drying his hair with a hairdryer, smiling warmly.
"Don't worry, Aunt Tamako. I'll take good care of Nobita's studies."
The small bathroom felt crowded as they stood close together.
Tamako's movements gradually slowed. After she turned off the hairdryer, the air between them grew thick with tension.
"Alright, Hiroshi. Close your eyes."
"Why?"
"Just close them."
Her tone was slightly firmer than usual. Hiroshi obediently sat on the edge of the bathtub and shut his eyes.
"You mustn't open them."
Tamako knelt gently in front of him. Her hands trembled slightly as she reached for the towel wrapped around his waist and slowly pulled it away, letting it drop to the floor.
Hiroshi's young cock sprang free — already half-hard, thick and heavy for his age.
Tamako's eyes widened behind her glasses as she stared at the veiny shaft up close. Her breathing quickened.
She wrapped her soft, warm hand around the base of his cock. Her fingers couldn't fully close around his thick girth.
Slowly, she began stroking him, pumping up and down with hesitant but eager strokes.
"Ah… Aunt Tamako…" Hiroshi groaned, his cock swelling rapidly to full hardness in her grip.
Tamako's cheeks burned with shame and forbidden excitement. She pumped him faster, her thumb rubbing over the swollen, leaking head.
"Does it… feel good?" she whispered shyly.
"It feels fucking amazing," Hiroshi growled softly. "Your hand is so soft and warm… Keep stroking my cock just like that, Auntie."
Encouraged by his dirty words, Tamako leaned closer.
She gave the throbbing head a slow, tentative lick, tasting the salty precum, then opened her mouth wider and took the fat tip inside.
Her warm, wet tongue swirled around it as she began sucking gently.
Hiroshi's hand moved to the back of her head. He pushed her down firmly, forcing more of his thick cock into her hot mouth.
"Mmmph…!" Tamako's eyes widened as he pushed deeper, the head bumping against the back of her throat.
She gagged softly but didn't pull away. Saliva immediately started dripping from the corners of her lips.
"That's it… Good girl," Hiroshi murmured, his voice low and husky. "Suck my cock deeper, Aunt Tamako. Take more of it in your slutty little mouth."
He gripped her hair tighter and began thrusting gently into her face, fucking her mouth with slow, deep strokes.
Wet, sloppy sounds echoed in the small bathroom
Gluck… Gluck… Gluck…
Tamako moaned around his shaft, her heavy breasts swaying beneath her nightdress. Her pussy was already soaking wet from the filthy act.
"Fuck… your mouth feels so good," Hiroshi groaned.
"You're sucking me so eagerly… Does my auntie like having a young boy's thick cock in her mouth? You're such a naughty MILF, Tamako."
He pushed her head down harder, forcing his cock deeper into her throat.
"Deeper… Yes, just like that. Choke on it. I want to feel your throat squeezing my dick."
Tamako gagged and coughed, tears forming in her eyes, but she obediently tried to take him even deeper. Saliva ran down her chin and dripped onto her heaving breasts.
Hiroshi's breathing grew ragged. He held her head in place and started thrusting faster, face-fucking her with more force.
"I'm close… I'm going to cum down your throat. You're going to swallow every drop like a good auntie, understand? Don't waste any of my cum."
Tamako moaned loudly around his cock, the vibration sending pleasure through him. With a few final, deep thrusts, Hiroshi groaned and exploded.
Thick, hot ropes of cum shot straight down her throat.
Tamako choked and gagged but desperately swallowed everything, her throat working visibly as she drank his heavy load.
Some cum leaked from the corners of her swollen lips and dripped down onto her chin and cleavage.
Hiroshi kept her head pressed down until he finished emptying himself, then slowly pulled his glistening cock out of her mouth.
A thick string of saliva and cum connected her lips to his shaft.
Tamako gasped for air, coughing lightly, her face flushed deep red, lips shiny and swollen with cum. She looked up at him with dazed, watery eyes.
He heard her quickly wiping her mouth and standing up on shaky legs. Footsteps hurried out of the bathroom.
Moments later, Nobi Daisuke's voice came from the bedroom.
"Tamako, where did you go just now?"
"My neighbor mentioned that drinking milk at night helps whiten the skin. I went to try some," she answered quickly, her voice hoarse and flustered as she slipped into bed.
Daisuke glanced at her curiously, noticing her flushed cheeks and messy hair.
"Has your sleep not been very good lately?"
"Mm… maybe a little."
"Sigh. Don't worry too much. Even though Nobita didn't do well today, he'll grow up eventually."
After speaking, the room fell quiet.
Night settled over the Nobi household once more, but Tamako lay awake, the thick, salty taste of Hiroshi's cum still coating her tongue and throat.
