He's still fucking her, but Tsunade is able to catch her breath… which means she can answer him when he asks her his next question.
"Tell me honestly, Tsu-na-de… why were you so ready to get down and dirty with little ole me like this? Was half-expecting you to punch my lights out when I pulled out my cock and slapped it down on your desk…"
Grunting and groaning and moaning, making all sorts of fun noises as he rails her into his desk, Tsunade still manages to respond… and much to Naruto's delight, truthfully at that.
"T-There's nothing little about you! Oooh, i-it's… f-fuck, it's all Jiraiya's f-fault! T-That bastard… we've b-been, oooh, fuck buddies since, mm, we were students of t-the Third H-Hokage…"
Lifting his brow at that, Naruto doesn't interrupt, letting Tsunade tell the story, even as he continues to fuck her from behind, greatly enjoying her sopping wet cunt wrapped around his cock.
"He… w-we drifted apart when I, f-fuck, when I met D-Dan, my first, ooh, true love… a-and then when, hah, Dan died, I left the, mm, village b-behind."
Tragic, but Naruto thinks he remembers this. Has something to do with the First Hokage's necklace that Tsunade gave him as proof of her faith in him, a necklace that he still wears under his clothes to this day.
"A-After you both, ah, tracked me down and s-saved my ass f-from Orochimaru and his p-protégé, I… J-Jiraiya and I rekindled our previous, mm, relationship…"
Huh, is she starting to get used to this sensitivity? Her breathing and her speech are both starting to even out. Frowning, Naruto heightens the first seal up to four times the norm, watching as Tsunade lets out a surprised squeal and cums around his cock again. Continuing to fuck her with all his might, he listens as Tsunade finishes her explanation.
"Mm, e-earlier, fuck, earlier, with J-Jiraiya, h-he refused to fuck, ooh, to fuck me… h-he toyed with and t-teased me, b-but he left me… unsatisfied…"
And there's that. A secret relationship between Tsunade and her fellow Sannin, though from the sound of things, one that was purely physical and never anything more. Naruto hums as he considers Tsunade's explanation. It does explain exactly why she was already basically ready and raring to go when Naruto started coming onto her, he supposed.
Meanwhile, as Naruto slowly nods, accepting Tsunade's explanation, the Hokage herself suddenly pauses and freezes up beneath him, even as he continues to thrust in and out of her cunt, causing her to orgasm every so often. But now that she's done talking, the constant cumming alone isn't enough to distract the Fifth Hokage forever.
"You… w-what did you do, N-Naruto? Why did I just, fuck, tell you all of that?"
Huh, she's already adapting to four times the sensitivity that fast? He's tempted to take her up to five and ignore the question, but that might not be enough. And if he takes her to ten again and turns her into a drooling mess, well, who's going to promote him to Special Jonin. So, grinning impishly, Naruto pats the ass cheek carrying the second seal he drew on Tsunade's body.
"That'd be this lovely darling, Tsu-na-de. See, what this seal does… is encourage it's bearer to tell the truth to the one who charged it in the first place."
Tsunade stiffens further and whips her head around, looking back over her shoulder at him again as she scowls angrily. The effect is somewhat ruined by how aroused she currently is though, the horny Hokage panting and mewling, even as she tries to level a glare in his direction and ignore the fact that his cock meat is buried deep in her squeezing, tightening twat and that she's loving every minute of it.
"Naruto, you-!"
Cutting her off with a smack to her fat bottom, Naruto grins.
"Earned my promotion to Special Jonin, perhaps? I'm sure I don't need to outline how useful THIS seal will be, do I?"
With the effects of the seal working away at her, Tsunade has no choice but to tell the truth through gritted teeth, as she tries to ignore how good his cock feels, burrowing away at her insides.
"No… you don't. F-Fine, Naruto… you've earned your p-promotion… but you'd better finish me off!"
Laughing, Naruto has no issue with that, beginning to piston in and out of her harder and faster by the moment. At the same time, he ratchets up the sensitivity of the first seal to seven, and slowly drives Tsunade into a moaning, drooling, constantly cumming mess over the next few minutes, until her clenching, squeezing cunt finally drives him straight over the edge.
With a loud groan, Naruto unloads right into Tsunade's womb, filling his Hokage with a nice, thick load of his seed, not even thinking of pulling out. He'll wonder why later… but at the moment, a certain fox is making sure he lives up to his end of their bargain, and all Naruto can think about is pumping the gorgeous blonde in front of him full of his white, hot cum.
Once he's done, he slowly pulls out… he half-expects Tsunade to be passed out, only to belatedly realize that she's not one of his civilian test subjects. Spinning around, Tsunade drops into a crouch in front of him, and hungrily takes his messy cock into her mouth while playing with her breasts. Sucking and slurping and bobbing up and down his member for a bit, she eventually pulls back… and Naruto can tell what she's going to do before she even opens her mouth.
To avoid stepping fully over the line to the wrong side of disloyal, Naruto asks the question he's been holding in reserve BEFORE the Fifth Hokage can outright order him to remove the second seal.
"So, what's Jiraiya's current mission?"
Unfortunately, he sort of… miswords it, really. Glaring daggers at him, the older blonde nevertheless answers… but it doesn't really help.
"He's investigating Akatsuki's main hideout, Naruto. Now, remove this seal from my ass… that's an order from your Hokage."
Grimacing, Naruto does as he's told… though only with the second seal, not with the first. Noting this, Tsunade raises a single brow.
"And the other one?"
Grinning somewhat cheekily, Naruto shrugs his shoulders.
"You didn't order me to remove that one, Tsu-na-de~"
With that, he tucks his cock back into the confines of his pants and steps away from Tsunade and her desk, making his way towards the door.
"Naruto!"
She's still not ordering him to remove it, and they both know it, despite her aggravated tone. So, Naruto keeps on walking, grinning, and whistling all the way out of Tsunade's office, her angry voice following him… but also tinged with just the right hint of lust and arousal and a desire for another round. Yeah… Naruto is definitely tapping THAT again sometime soon.
Although, that depends. He doesn't know WHERE Jiraiya has gone precisely, but he knows what his Sensei is dealing with… and has a fairly good idea of why the older shinobi left him behind now. The Akatsuki are after Naruto and every other Jinchuriki for good measure, so taking Naruto with him would be like Jiraiya delivering him right into the lion's den.
That said, Naruto has to admit, he's not sure what to do. One way or the other, he's gotta make a final decision here and now, doesn't he? Should he stay or should he go? Does he stick to Konoha, where everyone including his demonic passenger wants him to be… or does he go after Jiraiya and risk it all? Naruto of a few years back would have run off without a single second thought upon hearing what sort of danger one of his precious people was putting himself in.
But he'd grown up a lot these last few years, there was no denying that. Could he trust Jiraiya to handle this without needing him as back up? Should he stick around Konoha and do what Tsunade and the Fox both seemed to want him to do, and start up a clan?
He was at a crossroads, and one way or another, Naruto could tell that nothing would ever be the same.
