Piranha serves him well but Yuta can't manage to 'hold the mayo'...

Yuta's manhood was as straight and erect as a flagpole. With all the action she had gotten, Piranha's caramel pussy was wetted up as much as that shaft was, and there was no resistance or friction except a pleasant squeezing sensation as she gradually lowered her hips onto him and took his straining dick inside her, enveloping the head in her velvety folds and sliding all the way down to the base in a single long stroke. She could feel the cheeks of her big round posterior coming to rest against the warm surface of Yuta's smooth, hairless thighs. It seemed like he even trimmed his pubes down to nothing but a little patch of stubble, so she could feel her hot clit pushing right up against his pelvic bone as her tunnel squeezed him for all he was worth.

"Ohhh yes! Oh... heck! It's so tight!" Yuta gasped and his eyes bugged out with the sublime pleasure he was receiving. His hands squeezed Piranha's midriff so tightly that if she weren't so fit and toned herself, she might find it hard to breathe. First his gaze stared at Piranha's midriff and her belly button, as if he was trying to lock his eyes on where the head of his cock would be, buried deep inside her. Then his gaze drifted up to her face, where her own lips were wide open and moaning, eyes partly hidden behind the red visor she had kinkily slipped on.

The boy's hands slipped down over her waist to cup her ample backside, giving each firm, springy cheek a squeeze in turn before digging his fingers into both at once, his tan fingers leaving deep dimples in her soft chocolate skin. Piranha began slowly bucking her hips back and forth, starting with small gentle motions and leaving his rod completely engulfed by her tight cunt. His hefty balls were pressing tightly up against her taint and when she leaned back a little she could even feel that firm pair of nuggets brushing up against her puckered asshole.

"So how is it, Yuta? Do you like your, unhhh, belated birthday dinner?" Piranha started slowly lifting her gorgeous ass up off Yuta's lap and lowering it again. She didn't have to pretend at all when she let out a lusty moan at the feel of his cockhead almost slipping out of her pussy only to sink all the way back in.

"It's squeezing me... you're so hot and wet inside Miss Piranha, it feels like my dick is going to melt!" Yuta's mouth was hanging open and he was already starting to breathe raggedly - and when Piranha stepped up her game and began bouncing up and down with a gradually increasing rhythm, allowing him to hear the sound of her full ass softly slapping against his hips, his eyes only got wider.

"Yeah... oh, you're getting me so hot, baby. I think this was my lucky day, getting a customer like you. You already made me cum once, make sure you hold back as long as you can... you want me to cum for you again, don't you, Yuta?" Pirnaha struck a series of poses each time she sat all the way down on Yuta's lap... putting her finger up to her lip and pushing her chest out, then putting her arms down to her thighs and shimmying from side to side.

Yuta decided, in as much as he could have any rational thoughts anymore right now, that as nice as it had been to watch this black goddess's enormous breasts sway when she was walking or skating, watching them energetically bounce up and down while she was riding his cock was, in fact, the greatest thing ever. This was it, the high point of his life, no other experience, not even the sublime thrill of victory in in the 300 meter dash or getting a medal with real gold in it - heck, not even the hypothetical outcome of finally outswimming Aoi - could compare with this.

It felt like Piranha's pussy didn't want to let him go each time her hips lifted off of his, squeezing every contour of his manhood, but when she plopped herself back on him she relaxed, quickly engulfing all of him again. Sometimes when she took him all the way in, she sat there for a few moments grinding on him, rocking back and forth or waggling side to side to make sure that every possible millimeter of her inner folds rubbed up against the head of his dick.

A harsh squeaking sound coming from the cheap bedsprings beneath him sounded like a heavenly choir in this situation. Yuta got past his usual inclinations towards politeness and used both hands to give Piranha's smooth yet firm ass cheeks a double-handed spank, which made her yelp with surprise - but based on the giggle she followed up with, she didn't mind all that much. He had never imagined what it would be like having sex with a woman who was bigger than him... his teacher and a few lady's favors he'd earned at his high school were all petite girls. This exotic foreigner was pounding him down into the bed as she increased her tempo, making the bed bounce under him and making him feel like he was totally in her control.

She was saying something now aside from her cries of encouragement, "Oh yeah cutie, don't forget to..." but the rest of it didn't reach Yuta's ears in between the sound of rushing blood and the squeaking springs.

Yuta reached up with both of his hands, releasing her ass, and grabbed onto Piranha's huge breasts as the tempo of her ass slapping against his sweaty skin increased. That made Piranha toss her head back again and giggle with delight as she rested her hands down on his chest to help support her quicker pace of movement. His fingers sank into the squishy surface of her prized F-cups, half of them feeling the surface through the fabric of her top and the others dimpling the bare skin of her cleavage.

As if having her pussy pumping up and down on his shaft wasn't enough, the feel of groping her tits as they bounced in front of his eyes might've been enough to make Yuta have an accident in his pants, given enough time. He immediately realized he wouldn't be able to hold for long like this.

The foolish boy started thinking of his sister with her hands on her hips, glaring at him... Granted, for most boys his age, Aoi was the exact opposite of the mental image they would try to conjure up if they were trying to delay ejaculation. But Yuta thought about how contemptuous, yet unsurprising, she would be if she knew the very first thing her brother had done after being ejected from the party was pick up a hooker - that less than 45 minutes had passed between her tossing him into that pool, and Yuta having unprotected sex with a scantily-clad woman in a short-time hotel.

But the guilt didn't help, at all. Especially not when Piranha let out a trembling, extended moan of pleasure, trembles running through her body and transmitting into Yuta's fingertips. Her pussy got wetter around him, and she sat down as hard on him as she could, grinding against his pelvis and letting his balls get cradled between her ass-cheeks. What had she said again? Who knew? A full-body wave of pleasure overtook the foolish boy as he let himself go, helpless to move or even speak as a geyser of what he'd had pent up for a whole week exploded deep in her pussy.

"Ahhh... mmm... Oh, I can feel you're gettin' close... you ready for me to pull off and take you in my mouth...?" Piranha could feel his nuts throbbing several times, pressed tightly against her as they were, and noticed that his cock seemed to have swelled up inside of her... plus, she could hear and feel the shudders running up and down through the teenager's toned body.

After letting his head loll back and tongue hang out for a few moments, Yuta re-focused his eyes on the sight of Piranha sitting astride his hips just in time to notice her eyes taking on a slight crinkle of worry behind the visor she wore. "Ummm, ahh..." he stammered for a moment, still squeezing her breasts tenderly with his hands as if that would help soften the blow. "I'm sorry, Miss Piranha, your tight pussy and soft breasts felt so good that I waited too long. I... hehehheh... uh, I couldn't 'hold the mayonnaise'."

"WHAT!?" Piranha's mouth dropped open. "Are you fuckin' kidding me? Oh hell no...! Let go of me right now, let go, let go!!!" She roughly slapped his hands away from her chest tried to hop up off of him. Her mind was already racing. 'How many days ago was my last period? Onetwothreefourfive... six... seven... eight... nine days? That isn't good at all..' Piranha thought with a wince, caught between the pleasant sensations of her orgasmic afterglow and the alarm bells ringing in her rational mind.

Yuta had been enjoying the feel of her body so much that he reflexively grasped at her hips as she tried to pull off of his softening cock, but eventually relented as Piranha hopped up to her feet. Bent over and looking down between her own legs, she could all-too-clearly see the string of pearly white semen stretching between the head of Yuta's cock and her hairless caramel pussy lips. Several big sticky droplets dribbled out, a couple falling straight down onto her satisfied customer and another starting to run down her inner thigh with a warm tickling sensation.

"I'm... I'm sorry?" Yuta gulped. "But it felt-" he suddenly realized that wasn't an excuse and changes tactics, still unable to peel his eyes away from her erotic body. "I mean, I agreed to pay the full fee, isn't that part of it? What happened to 'following my heart'?"

Piranha whined as she put her hand down to her crotch - now that she was moving around she could feel a 'squishing' sensation with every move she took. "You... you fuckin' conceited... I told you! I must 'a told you ten times that you weren't supposed to cum inside of me!"

"Oh... Oh, yeah, now I remember." Yuta said in the same tone as if realizing where he'd left his house key. "I'm sorry, I don't have that much experience in pulling out of girls, I didn't know how short an amount of time I would have. Gee, and I thought the pressure of taking that first step when you hear the starting gun was intense! I think I'd need a lot more practice before I could master that one."

One hand cradling her dripping pussy - partly because she didn't want to make such a mess here that the owner got irate with her and told her to bring clients somewhere else - Piranha responded by giving him a series of hard punches on his chest before hopping off of the bed and standing on her tiptoes. Miraculously, her white crop-top had stayed in position through out all of this, but she quickly grabbed up her discarded pants and panties.

"Stupid-ass kid...Consider your time used up and then some! And you better put that payment on the table right now!"

Fortunately for Piranha, it seemed the young man had wanted to impress someone, because after collecting his pants and his wallet he was able to produce a sizable wad of bills. "H-here, Miss Piranha... I don't want you to be mad at me. I'll add an extra 1000, okay? Oh, I forgot about the hamburger... an extra 1500, then." He gulped and grinned nervously as the woman shuffled awkwardly away from him with her legs far apart. "That's okay, isn't it? I mean, since this is a business for you, you're on, um... the birth control pill, right?"

"NO!!" Piranha growled in exasperation. "Did I ever say I was?? That shit makes me gain weight like crazy! Isn't exactly like I'm on a low-calorie diet. Uuuughhh... how stupid can you get." she bit down on her plump lower lip and looked away from him. "Just... get out of here, already! I'm puttin' you on my official 'Do not serve' list, punk!"

Yuta looked disappointed and crestfallen at that. Quickly wiping himself off, he pulled on his khaki shorts and shrugged one last time before disappearing out the door.

Piranha barged into the cramped bathroom and threw open the shower, not even bothering to remove her top before turning the water on and aiming the detachable showerhead right between her legs as she stood in the cubicle in a broad, awkward stance. Still hyper-sensitive, the feel of the warm water splashing across her labia made her shiver and grit her teeth - to her overwhelmed nerves, more pleasure was almost like pain, at this point.

Perhaps he didn't cum that much? Only a few drops had fallen out of her when she stood up. But when she squatted down just a little bit, she felt a sudden rush of a strange sensation as a thick stream of white began pouring out of her only to be washed down into the drain. Apparently the conceited kid came like a firehose. Even after the stream became a trickle she felt sticky down there, and had to spread her pussy open with her fingers, dipping her index finger inside while directing the spraying water to wash any remainder out.

"Oh, darn, I forgot all about the hamburger. I wonder if I go back...? Nah, Miss Piranha probably needs it more than me right now, she was doing all the work, after all!"

Yuta hummed tunelessly to himself as he walked briskly back towards home, putting any lingering feelings of guilt out of his mind. Really, it was Aoi's fault, if she hadn't pushed him out of there he wouldn't have met that beautiful blue-haired girl Mew and followed her here. Oh yeah... Mew!

Rather than going home immediately, Yuta went up and down the streets looking for her. There were more than a few more women in racy neon-colored punk outfits waiting at the street corners and many invited him over with eyes or fingers, but Yuta decided against that - and besides, Piranha's pussy had milked every last drop out of him.

Mew was nowhere to be found among them. Well, of course she wasn't - she was clearly too sweet and innocent to be doing anything like that! Eventually it started getting late, and Yuta, not trusting himself to answer ANY questions from Aoi about where he'd been, decided to head home before it got dark and the streets became dangerous.
