“Nnhhmhh! Yeahh! Finally! You’re bringing out your ‘A’ game now, Naruko-Chan! Nnhhmhh! Keep an eye on the timer now, it’s got your number, and I’m not feeling ready to pop just yet. You’d better pull out all the stop..aaanhh! Fuuuck! Nnghh! That feels so freaking good..! Keep going..! Nhm!~” Issei said between heavy breaths of elation as he felt the girl smothering her tits together when bringing them toward her lips for a tri-fold sensation involving her lips and breasts. Her tongue came rolling out all over his glans again and again, noisily slurping it all while eying Issei and the timer. 

Gradually, she began putting in a lot more effort in her breast-swaying motions while ignoring the need to beat Issei at his own game, only thinking about how much she was enjoying the taste and smell of his cock plunging partially into her mouth.

“Mmnh…slrlrlrurpp…slrlrulrrp..mmh..hnhm…mmhmm..sllrrupp..srhrrhpp..slslrurrpp..mnghghmhh! C’monn..! Nnuugh!” Naruko voiced between lurid noises of suction and moans as she watched the timer ticking down to the last minute. ‘I can’t believe I’m saying this, but the smell..and the taste…of his dick between my lips…is nauseatingly addictive..! Nnhmh! I can’t get enough of it. Something’s changed! Nnhmm..nhmm…mnhmm…noooo! My time is about to be up and he hasn’t even let out a dribble of pre-cum yet either..!’

She panicked and started furiously swishing her tits up and down his shaft while hungrily slurping the tip of his cock even more strongly than before. She bobbed her head, weaving it between her tits in virulent bobbing motions as she cupped her tits tightly to bring them down his shaft even faster than earlier. She could tell he was getting close to cumming, judging by the volume of his moans and the sight of his cock throbbing heavily with his balls beginning to rumble underneath her breasts. Issei cast a look at the holographic timer beside him and smirked when he looked at Naruko, seeing panic in her beautiful blue eyes as she feverishly worked her tits down his cock to get him to explode. It was in the final five seconds, and Issei looked assured that victory was well in hand despite feeling ready to cum inside of Naruko’s tight, slimy mouth.

‘Nooooo! C’mon! Cum! Nnhm..mhm…nhm..mnhmm!~’ Naruko thought as the lurid slurping noises escalated into a faster cacophony of ‘music’ filling the room.

“Nnhmmh! Almost there! I mean the timer, not me..!  Nnh! Uuuuhhh..yeah! You’re doing a good job, by the way.!~” Issei commented aloud, enjoying the slick feeling of Naruko’s lips as she continued to massage his cock in vain while her lips felt the slow rumbling of his ginormous appendage getting ready to go off. 

But not soon enough, and in her eyes, it seemed as though he was completely in control of the impulses of his body.

Beep..beep..beeeeeeep!

‘Damn it all! I lost..! Gaaaaaaaaagghhh!’ Naruko wailed in despair as she heard the holographic hourglass deliver the sound of her resounding defeat, beginning to remove her hands from her tits as she was ready to remove her mouth from the tip of his cock as well. That was until Issei’s right hand lunged out to grab the back of the girl’s head and forced her to swallow his cock all the way to the back of her throat! She was being held there above his waist with her entire mouth being filled up by his cock and forced to give him an impromptu deep throat. “Gnngghghh! srlrlrurupp..sshrlrlrurpp…srlrhrupp..srlrlrurpp..mmh..nngh..mnghgh..slrlrurururpp…srlrlrup....nghgmh!”

He continued holding her face there as he enjoyed the slimy visage of her slender throat for a few more minutes just before he ejaculated deep inside of it.

!

“Nngngghhhh! Here it comes! Gobble it all down, Naruko-Chan..! Mmnnghm!~” Issei howled loudly with pleasure as he felt his release coming forth in a surge from his length. His cock spewed forth thick blasts of sperm that came with incredible force down her throat, forcing the girl to swallow it all as quickly as it came, with the hope of avoiding being drowned in his sperm!

“Hmmpffbbhhhh!!! Gulp…gulp…..gulp….gulp….gulppp…gulpp...mngghhbbhhfff!” Naruko let out a series of muffled moans and grunts while her cheeks pumped outward, becoming full of Issei’s cum. Her throat bulged repeatedly as she struggled to swallow every last ounce he deposited into her esophagus for about a minute and a half till he was finally done and let go. ‘Uuughhh! How much spunk can this guy produce…!? Seriously..! It's as if he were a horse..! There’s sooo much..! Aaaaaahhhh..! Let go of my head already, bastard..!~’

Just when he finished cumming like a firehose inside of her mouth, he let go of her head, which resulted in Naruko throwing back her head with her mouth sputtering open in a series of choking coughs and gagging noises.

“Ahh…yeah! This is what I was talking about when I came here..! Heh! That Ramen-loving idiot brother of yours should’ve just brought you in from the start and left me with you for this mission of keeping me company. This arrangement is waaaaayy better, don't you think?~” Issei remarked, insulting Naruto a little after having enjoyed the slippery suction of his sister’s throat. Naruko herself wanted to bite back with an insult of her own, but she was too busy choking to really care or consider answering back while she recovered.

“Uuuuughgh! Cough..cough…..ggnghh! Gackk! uuugughhh!...huff..huff...you dick..! cough..cough...you came so much you could've choked the life out of me with that amount…! Uughh! I’m never going to forget the taste of your semen on my lips now….” Naruko said aloud, coughing a bit more as some of Issei’s sperm dripped down her chin and into the waters, with much more of it having gone down her throat. She raised her head back a bit to let the rest lingering around her palette to drip down into her stomach with a few more gulping sounds until she was finished. “Uuugh! huff…huff…...oh,  right….I lost….”

“That’s right, according to this timer here, you couldn't get me to pop my top before your given time was up. That means I officially win, fair and square….and you know what that means, don't you?~” Issei asked with a devilish smile on his face, eying Naruko’s massive breasts and examining the rest of her highly voluptuous body still halfway submerged in the water. The look of embarrassment and shame on her face made her look adorable, and he partially wondered if she was going to beg him for leniency on their wager till he heard her sigh.

“Fine….I guess that means you want to fuck me now, right? I gave my word and I won’t go back on it. Uugh…let’s…do it over there on the border outside of the Onsen’s waters so that we..don't prune up?” Naruko shakily suggested while hugging her arms into her hands, allowing her bulbous breasts to pop outward and jiggle a little in front of Issei’s eyes. It was purely unintentional on her part, yet it stoked the fire inside of his libido as he gleefully arose from his spot atop the underwater basin and offered her a hand.

“Yes, let’s do this. We’ll begin by going a little basic in terms of positions. I can guess that you’re probably a virgin, since you’re so unsure about this and look so bashful like a virgin maiden. Here I thought Kunoichi were trained to be sex spies from training earlier on, but that makes this even better. Come along and let me make you into a woman..” Issei offered with a suave, hungry voice that sent chills down the blonde’s spine as she took his hand and was led out of the Onsen’s waters with her towel being left behind. Issei got a good look at her supple ass and found himself salivating at the sight of her compact pussy with barely any pubic hair above her mound. What really caught his eye was the unique ‘marking’ on the surface of her stomach in the form of a fiery seal with eight ends and a spiral sign in the center. Ultimately, Issei hardly cared about that mark and didn’t ask, as the rest of her body was what he marveled at while she got out of the water. Her hips were wide and her waist was slender, making the rest of her gorgeous body perfect in his eyes. “Umffhh! Hot damn, I got lucky coming to Konohagakure after all! You’ve got a banging, hourglass body that’s perfect for me. Heheh.!”

“Uuuughh..! Kami, help me..” Naruko adorably whimpered as they took a few more steps to where a spot along the border rim of the Onsen was smooth enough to be comfortable to lie back on. 

She got down on it first and lay flat on her back with her face red with shame while Issei got on top of her, spreading her legs around his sides while guiding his massive cock over to the cusp of her cherry-colored sex with anticipation. Just seeing it above her, casting a shadow over her chest and stomach, made Naruko feel nervous while also feeling a tingle of wetness between her folds. 

‘I.. really shouldn't be feeling aroused at all by this..! Uuuuhh! That thing is going to split me open once he pushes it inside of me.’ Naruko thought as Issei held up each of her thighs and guided the thick, bulbous head of his dick into the cusp of her folds, Naruko braced for the worst as he shoved his pelvis forward with a sharp thrust and a smile of glee.

“Hnnghh!~” Issei grunts as he pushes himself forward, sliding his dick into the girl’s virgin pussy and breaching her once-protected hymen in a single thrust!

Squealch!

“Gggrrrggnghhhhhh! Aaaaaaaahhh! Ooohhhhh! My…hymen..! Uuughgh! Oohh..the pain…b-b-but…it feels…too good…having such a big thing inside of meeeaaaaaaaaaaghghhhh!~” Naruko cried out in slight pain at first, then wailed in ecstasy as her legs shot out with toes curling around Issei’s sides.
