Kushina froze up.
"Huh? I want to take a shower, mum," Naruto said and scratched his head. "And since you were taking a very long time, I thought we could take one together like before."
"Get… get out of here," Kushina growled. "Get out of here!"
"Okay, but I'm going to use the shower upstairs in your room to clean up," Naruto said and turned away from the frosted glass. "Dad might wake up when I do though. If he asked what I am doing, what should I tell him?"
Kushina widened her eyes.
Before she could say anything, the silhouette of her son vanished.
She hastily pushed open the frosted glass door, but before she could step out, she noticed her son was on the floor of the bathroom, rubbing his head.
"Sorry, I slipped," Naruto groaned. "There all these slippery puddles everywhere."
Kushina froze up at the sight of her son and especially at his bobbing cock.
It was still stiffened after all that had happened.
If her husband could keep it up for this long, it would have been a blessing.
Sadly, age had an adverse effect in her fulfillments.
"You're staring, mum," Naruto said and gave his cock a few strokes. A bead of pre-cum formed at the tip, telling him that his balls had been loaded and readied. "But I can too."
Kushina had a mind to cover herself.
It seemed pointless since her son had seen everything already.
Still, standing naked in front of him and wet – in both sense of the word – was still indecent.
"Sochi, what we did was wrong. You know that, don't you?"
"I didn't feel wrong," Naruto responded. "It was the best thing that ever happened to me. And I should thank you. Thank you, mum. I just wish you didn't run off before I could give you a special thank you and making a mess everywhere."
Kushina wondered what his "special" thank you was, and seeing his huge cock wrapped in his hand gave her some illicit thoughts.
She shook her head. "And why do you think that is? If you didn't cum so much, there wouldn't a mess everywhere."
"That's why I want to put it in your mouth, mum," Naruto said. A small smile formed at the corner of his lips. "That's way, there is no evidence."
Kushina gapped.
She tried to think of a good comeback, but the lingering sensation upon her tongue and taste-buds clouded her mind.
She imagined stuffing her mouth with her son's huge penis while trying to milk out the salty creamy of savory richness from his balls.
The reward would be overwhelming, bringing her to absolute ecstasy instead of this swelling guilt.
She would be satisfied.
"I heard it called a blow job," Naruto continued and got off the floor. He smiled at his mother on his approach. "I wonder how it feels, I mean for you. Is it like kissing? I wouldn't know. I have never kissed anyone before."
"You never kissed anyone before…?" Kushina questioned.
She never saw her son with any girl before.
He did chase after several when he was younger despite all the rejections, but he stopped abruptly a couple of years back.
She didn't think too much of it at the time, but now, being constantly rejected could have destroyed his confidence.
"Well, I kissed you," Naruto said and gave her a kiss on the cheek, "and I like kissing you."
"Sochi… I'm flattered, really, I am, but we can't," Kushina uttered, trying to look at her matured son and keeping her flimsy guard up.
He had matured in ways she had never imagined.
And before she realized it, her bare back was pressed against the wall of the shower as he cornered her.
"Just let it go, mum," Naruto said and pressed his lips against her mouth.
His lips parted, inviting her to do the same so their tongues could dance.
But she didn't. She couldn't just let it go.
Kushina held her lips closed, resolutely.
Even if she couldn't muster any strength to stop his incestuous advances, she mustn't follow his gesture and gave in to his teenage lust.
In her mind, she believed the talk must had brought it to the surface, and since she was the only woman he had ever acquaintance with, he couldn't help but use her as an output for his lust.
"You need to be more forceful, more dominating!" Kurama called out. "C'mon, show me that you're the greatest at everything you do no matter what! Surpass all that is in front of you!"
Kurama grinned deviously in the mindscape when Naruto gripped his mother's bubbly butt and pulled her nakedness into him, grinding his steel hardness against her soaking crotch, sliding it up and down her navel as if he was trying to penetrate her.
"No! Stop! You can't do that!" Kushina shouted and gripped her son's shoulders in fear.
The moment she did, his tongue shot forwards and into her orifice to seek out a partner, and she couldn't shut her mouth without biting him.
"Mmmmm!?"
Kushina attempted to evade his tongue, but it was a futile attempt.
And once she was caught, she gave up and tangled with him while exchanging bitter sweetness.
When his lips finally parted from hers, she bit her lower lip hard, trying to forget the lustful sensation a moment before.
"Do you like kissing me?" Naruto whispered into her ears.
"No," Kushina responded weakly.
"Ah!" Her body shivered when he nibbled on her ear.
She was losing control of her body.
And with his muscular frame pressing tightly against her, pinning her to the wall of the shower, she couldn't get away even if she wanted.
"Please stop… please let me go…"
Kushina pleaded.
"I will if you tell me the truth," Naruto whispered and licked her ear, making her trembled. He could feel the warmness spreading over his cock. It was oozing out of her gender. "Tell me the truth, mum. Do you like kissing me?"
Kushina swallowed.
"Yes, I like kissing you, Sochi," she admitted. "But not like this, not like this. This is wrong! I can't be doing this… please… I can't…. we're can't do this…."
Naruto paused and moved his head back.
His mother was covering her face, obscuring her tears with her hands.
She was genuinely scared, frightened at what she might do if he pushed further, just a little bit further.
She must have felt guilty for bringing this outcome, and what started as a game to see how far she would go had become something else.
It was no longer a game, and he felt he couldn't stop even if he wanted to.
Kurama narrowed its eyes, realizing that Naruto was having a second thought. "How disappointing… sex is a pleasurable activity that everyone does. If you two can help each other and satisfy your desire, you both would benefit. Besides, family helps each other out, don't they? If only there is a way to resolve her of her guilt."
There was a way, Naruto knew.
His mother wanted it from the wetness in her crotch, but she won't act on it without being stricken with guilt.
If that was the case, he could absolve her of all guilt.
Being forced into it wouldn't make her guilty. He placed his hand around her hand and pulled it from her face while taking a step back from her, freeing her body.
"I want you to put your hand on my cock," Naruto requested and forced her hand onto his raging cock, letting her feel the raw maleness of it.
She tried to fight it at first, but once her fingers wrapped around his cock, she gave in.
Without being told or guided, her hand pulled and pushed along its girth.
"Make me cum, mum. I want to cum."
