Ninja Gaiden Koibito

Ninja Roses: Calibration Test


“Yes, Ryu! That’s right! Drive it in deep!” Tina moaned, sweat pouring down her smiling face as she braced herself against the isolation chamber’s examination bed. She was bent over at the waist, her enormous breasts lying on the thin cushions of the bed. Her strong legs were spread in a wide stance while Ryu stood behind her, thrusting fast and hard. His muscular body glistened with sweat, his muscles bulging with power as he pounded his thick cock into Tina’s tight, wet slit with perfect rhythm. Tina felt the hard organ plunge into her, and she heard the loud slapping of Ryu’s hips against her firm buttocks. It was music to her ears... “Uuuughhh! YEAH! That’s the WAY! Aaaaah!”

“Nnnnnnghhhh!” Ryu groaned, gritting his teeth with pleasure as he felt Tina’s vessel squeeze his hard shaft with every thrust. The friction between their intimate flesh was electrifying, just as it always had been. But feeling the blond American bombshell’s hot womanhood wrapped tightly around his hard cock was never going to get old. “Yes, Tina! Oh! Rrraaagh!”

“Vitals looking good.” Lisa said over the intercom from behind the glass observation window. She had switched out the two-way mirror in exchange for regular transparent glass, as there was no real reason for Ryu and Tina not to see her. In fact, Lisa was certain that Tina enjoyed an audience. Many of the girls had dropped by, some for a few minutes, others for an hour or two. Makoto had almost fainted when Ryu had pressed Tina against the window, with Tina’s magnificent breasts just inches from Makoto’s face on the other side of the glass. The poor girl had run out, embarrassedly apologizing about feelings of inadequacy. Lisa was sure she would recover.

“Oh hell! You sure I can’t go in and get myself some of that?” Dixie asked, sitting next to Lisa. She had been observing with her for the better part of two hours now.

“I’m sure, Dixie.” Lisa laughed, having heard Dixie ask the same question nearly a dozen times already. “I have a specific schedule for these tests. Besides, if you wait to be with Ryu during the prepared event, it will be much more memorable.”

“Lookin’ at the way Tina’s ripping into him, I don’t think he’ll walk for a week.” Dixie whistled as Tina knocked Ryu onto his back and pounced, riding him brutally while the ninja fondled her bosom.

“Oh, he’ll be more than ready.” Lisa assured her, glancing at her instruments. “They’ve already been in there for two weeks now.”

“They’ve been going at it non-stop for two weeks?” Dixie asked in shock. “No way! They really don’t get tired? That’s amazing!”

“It’s more than that. Beside no sleep, they haven’t had water or food the entire time either.” Lisa nodded. “Heck, Tina hasn’t even needed to shave her legs. Look at them! Still smooth as silk.”

“That don’t make any sense.” Dixie shook her head, her eyes still glued to the two lovers as they tore around the isolation room.

“It’s as though their bodies are being perpetually kept at the absolute optimal peak condition for sex.” Lisa said, her voice full of awe. “It’s scientifically impossible.”

“It’s like magic.” Dixie said in a hushed voice.

“Exactly.” Lisa nodded. “This is Bayonetta’s spell at work. Ryu already had amazing physical stamina, and after recovering from Doku’s original Fiend curse, he was immortal. But this new fast healing and limitless sexual performance has to be Bayonetta’s doing.”

“Bless that witch!” Dixie laughed, slapping Lisa on the shoulder.

Lisa couldn’t help but smile at Dixie’s delight. She watched as Tina and Ryu thrashed together, bringing each other to yet another orgasm. Lisa reached over and flipped a switch on the console nearby.

“I’m hosing you kids down again!” She called over the intercom. Water poured down from nozzles in the ceiling of the isolation room, washing the room clean along with Ryu and Tina. They continued on, rolling across the cold metal floor, Ryu thrusting away with Tina wrapped around him, their lips locked in a passionate kiss.

“Is he coming inside her every time?” Dixie asked.

“Yes, but Leifang’s herbal tea should be effective for the better part of this next week before she needs another cup.” Lisa nodded.

“Yeah, but…” Dixie’s jaw hung open for a moment as she contemplated the implications. “They’ve been screwing for two weeks, and he’s been coming inside her every time, but they haven’t had a thing to drink or eat? How’s he not running out of ammo?”

“Bayonetta’s spell again.” Lisa explained. “They’re both sweating and producing the regular fluids, but they simply don’t dehydrate.”

“So…uh… How much, um…” Dixie hesitated, uncharacteristically bashful. “How much has he…uh… you know…. Produced?”

Lisa handed her the last readout sheet and waited for her reaction. She wasn’t disappointed.

“Holy COW!” Dixie’s eyes were as wide as dinner plates. “Oh now that’s…”

“A lot.” Lisa nodded, smiling mischievously. Then a sobering thought occurred to her. “Yeah. Be glad that DOATEC isn’t around to collect all that DNA material. God knows what they’d create with that much super-ninja essence.”

“I reckon it wouldn’t be nothing good.” Dixie agreed solemnly. Then a grin curled her lip. “But I guess this means there’ll be plenty for everybody when the time comes.”

“Oh, you bet there will.” Lisa returned her playful grin.

The door behind them hissed open, revealing Candy Cane wearing her favorite schoolgirl outfit, with white blouse tied at the stomach and a short red skirt. Her brilliant red pigtails bounced as she trotted inside and she stood just behind Lisa and Dixie, setting a hand on either woman’s shoulder.

“How’s it going today, ladies?” She asked, licking her lips as she looked through the observation window at Tina and Ryu. “Oooh! Holy crap, I think they’re actually getting wilder!”

“You’re right.” Lisa nodded, studying a readout screen. “Ryu’s thrusts are twenty percent stronger today than yesterday. I think his body is finally starting to seek out Tina’s limits.”

“Tina and Ryu have never exactly been gentle with each other, sugar.” Dixie giggled.

“True.” Lisa admitted. “But Ryu has always held back. Not consciously, of course, and it’s not as though he doesn’t bring all of his skills to bear; but his ninja trained body is capable of incredible power. That same training kept his body in check, making sure none of us were injured. But now that Tina has received the Dragon Essence, she can take whatever he can give. And his body is just now realizing it.”

“Wait… Dragon Essence?” Candy blinked. “What’s that?”

“That’s the name we came up with for Ryu’s health-regenerating immortality.” Lisa explained.

“Dragon Essence.” Candy said slowly, nodding with approval. “Nice ring to it. Hey, are they taking requests?”

Lisa reached over and activated the intercom. Tina and Ryu’s moans and screams of pleasure crackled through the speaker. “Go ahead. You might have to shout, though.”

“Hey, Tina!” Candy called over the cacophony. “Let’s see some reverse-cowgirl!”

Ryu had Tina underneath him, his face buried between her grandiose breasts as he thrust away. Tina glanced over and gave Candy a wink before reaching down and grabbing the back of Ryu’s head, her fingers grasping his thick dark hair. She rolled Ryu underneath her and sat up, grinning with delight as she twisted around.

“Yes! Aaaaaah!” Ryu moaned as Tina spun around on his cock to face away from him. He reached up and ran his hands down Tina’s bare back to her firm, shapely buttocks. Tina braced her hands on Ryu’s knees. She began bucking her hips, riding Ryu’s stiff shaft and relishing every stroke.

“That’s the way! Yeah!” Candy whooped excitedly, giving Tina a thumbs up.

“Mmmm! Happy to please! Oooooh!” Tina returned the gesture, trying to maintain a casual smile while working Ryu’s cock inside her.

“So, Lisa.” Candy said as the intercom switched off. “The girls are saying that Ryu has an unlimited supply of spunk.”

“Lovely way to put it.” Lisa made a face. “But yes, he’s outputting sperm at full capacity with every orgasm.”

“But every time he’s coming, he’s inside her, right?” Candy asked, her eyes locked on Ryu’s muscular arms as the ninja sat up and reached around to fondle Tina’s massive breasts.

“They seem to enjoy it that way.” Dixie answered, her hand absently massaging her right breast though her cowgirl outfit.

“What are you getting at, Rebecca?” Lisa asked Candy Cane, frowning with confusion.

“What if she was just jerking him off?” Candy asked. “Or was giving him a blow job, or what if she was just pumping him with her boobs? You think he would still be shooting forever?”

“Dang, Candy!” Dixie whistled. “You really are a naughty girl!”

“That’s an interesting point, however.” Lisa nodded in thought. She reached over and activated the intercom once again. “Tina! Ryu! Sorry to boss you around again, but I need you to stick with manual stimulation until further notice.”

“You heard her, Ryu!” Tina hollered, dismounting the ninja and standing. Ryu jumped easily to his feet and faced her. Tina pulled him into a deep kiss and her right hand slid down his chiseled abs and grabbed his member. Her fingers wrapped around the thick shaft, feeling his hard length pulsing with vital energy. Ryu moaned into their kiss, sending a thrill up Tina’s spine.

“Go on, girl.” Dixie said in a soft voice, knowing that the intercom was turned off. She licked her lips, watching as Ryu’s strong hands moved over Tina’s bare back. Then Tina began stroking Ryu’s cock in her hand and Dixie’s face lit up with a brilliant smile. “That’s it, sugar! Yank on that cock!”

“Aaaargh!” Ryu grunted, breaking the kiss as he felt Tina’s hand pump him. “Tina! That’s….nnnnghhh!”

Tina grinned, her eyes wild. She grabbed Ryu’s shoulder and turned him around, facing away from her. She pushed him toward the observation window. Ryu leaned forward, bracing his arms against the clear glass. Tina pressed up against him, her warm, luscious breasts against his bare back, and reached around Ryu’s waist to grab his cock with both hands.

“Let’s rock and roll!” Tina shouted aggressively, throttling Ryu’s manhood with all her might. And Tina was an incredibly strong woman. Her arms rippled with power, and her hands blurred around Ryu’s cock, vigorously pumping his rigid member. Tina chewed on her lower lip in concentration, giving it her all.

“Ahhh! YES!” Ryu growled, leaning against the observation window as Tina’s hands ravished his hard, pulsating manhood. Her sheer strength was astounding, and the pleasure that coursed up from his loins threatened to overwhelm Ryu’s mind. Ryu looked through the window, seeing Lisa, Dixie and Candy watching with rapt attention.

“Oh…wow…” Candy said breathlessly.

“DAMN!” Dixie shouted in disbelief.

“That’s… amazing.” Lisa murmured quietly.

The three women watched Ryu’s muscular, streamlined body strain with pleasure against the window; his long, thick cock pointing straight toward them with nothing but the clear window between him and them. The intercom was on, and they could hear every grunt and heavy breath as Tina mercilessly stroked him. Ryu’s perfectly toned muscles rippled with power, sweat pouring down over his chiseled pectorals and across his defined abs. His powerful thighs flexed as he fought to keep his footing, his knees weak with pleasure.

“He’s gonna pop!” Candy Cane squealed with anticipation.

“Come on, baby!” Tina purred in Ryu’s ear, her marvelous breasts rubbing against his back. “Come on! Let’s see what you got in there!”

“Raaaaargh!” Ryu arched his back, his hips lurching forward as he came. His cock convulsed, leaping in Tina’s hands. A deluge of his seed shot forth, splattering against observation window in several strong, potent volleys. Tina’s hands milked his shaft, pulling in time with each shot.

“Oh man, I gotta… I gotta…” Candy Cane bounced up and down on her feet, licking her lips as she saw Tina resume pumping Ryu’s cock once again.

“Patience, Rebecca.” Lisa said, trying to sound calm. She reached up and fidgeted with her collar, feeling incredibly hot. “We’ll get our turn.”

“Doesn’t mean we gotta just sit here!” Dixie declared with fierce determination. She slapped her lap and turned to Candy Cane. “Get over here, darlin’!”

“Oh, you got it!” Candy Cane grinned, already untying her white blouse and tossing it to the floor. Her perky breasts jiggled as she slipped off her skirt and rushed around to sit on Dixie’s chap-covered lap.

Dixie reached around and cupped Candy’s firm breasts with both hands, squeezing the younger girl’s bosom. Candy giggled as she saw Ryu’s eyes widen.

“Damn, Candy!” Dixie whistled, feeling Candy’s substantial breasts in her hands. “You’ve grown up, girl! These have gotten way bigger since the last time we had a match.”

“Thanks, but I don’t think they’ll be as amazing as yours.” Candy sighed resignedly.

“Size ain’t everything, sugar.” Dixie grinned, giving the young girl’s nipples a pinch.

“Ooh!” Candy yelped with a bit of pain, but mostly shock and a healthy dose of pleasure.

“These boobs are perfect on you.” Dixie said, massaging Candy’s bosom. “Downright irresistible.”

“Uuungh!” Ryu moaned as Tina jerked hard on his cock, his eyes still glued to Candy Cane’s supple breasts.

“Hell, since Ryu’s gettin’ a hand-job, why don’t I just…” Dixie trailed off, letting her right hand move down over Candy Cane’s flat stomach to the cleft between her slender legs.

“Dixie…” Candy inhaled sharply, feeling the cowgirl’s fingers dance over her nether lips. “That’s… hell yes!”

Lisa swallowed hard, glancing between Candy Cane’s spread legs and Ryu’s throbbing erection. The room felt incredibly warm, and Lisa knew it had nothing to do with the lab’s thermostat.

“Look at that, Ryu!” Tina giggled into Ryu’s ear, twisting her clenched fist around his hard cock while glancing over his shoulder at Dixie and Candy. “We’re getting some free entertainment!” She caught Dixie’s eye and smiled. “Wanna race, Dixie?”

“First one to get theirs to come?” Dixie asked with a sparkle in her eyes. “Oh, you’re on!”

Dixie plunged two fingers into Candy’s slit, wiggling them around inside her hot flesh. Candy bucked in her lap, her eyes wide with ecstasy. Tina renewed her grip on Ryu’s manhood and started jerking wildly, throttling his long, thick shaft. Ryu and Candy let out moans of pleasure.

“Di-Dixie!” Candy stammered, her pigtails swinging back and forth. She reached up and grasped her own breasts, fondling herself as she watched Tina’s merciless onslaught on Ryu’s member. His shaft was pointing straight at Candy, and the young girl remembered all the pleasure that hard, hot and throbbing cock had given her. She remembered how Ryu had thrust deeply inside her, powerful and relentless. Dixie’s fingers drove deeper inside her, and Candy cried out with delight. “Yes! Aaaaah! More, Dixie!”

“That’s it, sugar!” Dixie encouraged her. While her right hand worked between Candy’s legs, Dixie’s left hand roamed over the schoolgirl’s toned abs and down along her upper thigh, feeling her silky-smooth skin. “You are one finely shaped girl!”

Ryu groaned with pleasure, gazing intently as Dixie’s fingers spread Candy’s nether lips apart, giving him a wonderful view of the girl’s luscious pink flesh dripping with arousal. Tina’s hands pumped his cock, sending intense waves of pleasure through his loins. Ryu could feel another orgasm approaching, and he braced himself firmly against the observation window.

“Ooooh! I’m gonna come!” Candy squealed, her firm breasts heaving as she breathed in the air her body desperately needed. Sweat glinted on her forehead and a trickle ran down her throat, across the collarbone and down her cleavage as she squeezed and groped her breasts.

“All right!” Dixie nodded proudly, twirling her fingers inside Candy’s hot sheath. She grinned over the younger girl’s shoulder at Tina. “Hear that? My girl’s a comin’!”

“Oh yeah?” Tina retorted, sweat trickling down her face. “Get a load of THIS!”

With a mighty heave, Tina leaned back, pulling Ryu up and off his feet. Tina’s powerful legs strained with effort, supporting the ninja’s weight. Ryu reached back, grabbing the back of Tina’s head for support. He looked down and saw Tina’s hands become a blur around his erect cock.

“Aaaaaarrghhh!” Ryu yelled as pleasure flowed from his loins to every tip of his fingers and toes. He had not come yet, but it would be mere moments until the critical moment.

“Holy CRAP!” Candy Cane gasped in shock as Tina went wild, pumping Ryu’s cock at seemingly impossible speeds.

“Incredible!” Lisa gaped in total awe at Tina’s remarkable strength.

“Damn!” Dixie howled with excitement. “Now THAT’S the Tina I know!”

“I’m coming!” Candy screamed, overcome with both Dixie’s skilled fingers and the erotic sight of Ryu’s manhood being pumped just a few yards away. “More fingers, Dixie! I’m coming!”

Dixie complied, driving all four fingers into Candy’s tight slit while her thumb stroked the girl’s clit.

“TINA!” Ryu roared his lover’s name, feeling his climax building in him. Tina’s lips were next to his ear and he felt her hot breath, and he could feel her enormous bare breasts under his back.

“Come for me!” Tina hissed in his ear, her voice low and sensuous. Her hands squeezed down, yanking on Ryu’s cock with all her strength.

“RRAAAARRGHHHH!!!” Ryu’s voice shook the observation window in its frame as his orgasm blasted through his body.

“Dixie! I’m…. AAAAAAAHHHHHHH!!!” Candy wailed with ecstasy as she came, her nubile body thrashing in Dixie’s lap. Candy’s eyes tried rolling back in her head, but she fought to maintain focus on Ryu’s groin. She saw his testicles clenching and then a surging torrent of his seed shot from his cock.

“Yeeehaaw!” Dixie exclaimed, holding Candy Cane’s naked body as steady as she could while the younger girl rode out her orgasm. Dixie watched the deluge of Ryu’s seed erupt again and again as Tina’s hands pulled and jerked his convulsing cock.

“So much!” Lisa said breathlessly as Ryu’s loins produced a seemingly endless ejaculation. With each stroke of Tina’s hands another potent volley shot forth up into the air with amazing force.

“Aaaagh! YES! Nnnnnghaaa!” Ryu gritted his teeth as he continued to come. He had never experienced such a prolonged orgasm, but it was spectacular.

“Keep going, Tina!” Lisa called over the intercom. Her eyes jumped back and forth between Ryu’s cock and the sensor readout. The total volume Ryu was outputting was impossible.

“Come on, big boy!” Tina growled, her amazing body rippling with muscle. Sweat streamed down her as she held Ryu aloft, pumping his erupting cock with both hands. “Give me all of it! Keep it coming!”

“Tina! Uuuungh!” Ryu sucked in breath while his body continued to spasm in orgasm. A firestorm of ecstasy burned in his loins as he felt continual release; each volley of his seed feeling just as satisfying as the last.

“Lisa, I have to try something!” Tina shouted over Ryu’s pleasured shouting.

“I need to know if this has a limit!” Lisa shouted back. “Keep him coming!”

“Don’t worry, I will!” Tina replied with a sweaty grin.

Tina lowered Ryu back to his feet, and Dixie, Candy and Lisa were startled as Ryu’s seed began splashing loudly against the observation window. Tina moved quickly around in front of Ryu, keeping at least one hand pumping his manhood. The blond vixen giggled as Ryu’s hot seed shot narrowly missed her thighs as she moved to face him. Tina released Ryu’s cock and jumped up into his arms. So many times had she executed this maneuver that the ninja’s pulsating rod slid into her perfectly, without assistance.

“Oh YEAH!” Tina wailed as Ryu’s hard cock plunged up inside her. She clung to him, feeling each eruption of his hot seed filling her. Tina began moving, undulating her voluptuous body against Ryu, wiggling her hips and churning his cock inside her as he continued to come.

Ryu’s hands cupped Tina’s firm butt and his muscular arms bulged as he assisted her body’s movements as she ground against his loins. They locked gazes, his green eyes staring into her crystal clear blue eyes.

“I can feel you coming!” Tina gasped in rapturous joy. “Oh… and coming… and COMING!”

“T-Tina!” Ryu pressed his forehead against hers, staring into her eyes as his orgasm continued to shake him to his very core.

Candy Cane leaned back, resting her head between Dixie’s massive breasts as they watched in awe. Tina’s vessel overflowed with Ryu’s seed and yet still he came, pumping more and more of his essence into Tina’s tight, hot sheath.

“This is amazing.” Lisa gawked at the sensor readings. “He’s outputting an unbelievable amount! There’s no end to it!”

“I’ve never…Aaaaah… felt anything like this!” Tina moaned, grinding against Ryu while his cock filled her with his hot seed again and again. It felt like liquid fire flowing into her, creating a warmth inside that radiated throughout her body. And she could feel Ryu’s body shaking in endless orgasm, and she saw his eyes full of ecstasy and love.

“C-Come with me, Tina!” Ryu managed in a strained voice, every muscle in his body straining in orgasm. “I….AAARGH!... I must share this with you!”

“Oh, Ryu!” Tears of joy streaked down Tina’s cheeks and she covered Ryu’s lips with her own in a passionate kiss. Her hands clawed at his powerful back while her hips went wild, churning his erupting cock deep inside her. The delicious friction of his hard member against her hot inner flesh coupled with the unrelenting deluge of his seed brought Tina to the brink and beyond.

“RYU! I’m…I’m…YES! YES! YES!” Tina whipped her head back, her enormous breasts jiggling in Ryu’s face. Her orgasm ripped through her sublime body, curling her toes in excruciating ecstasy.

“TINA! AAAAARGHH!!!” Ryu cried out, his lips fastening down on Tina’s right breast, suckling her erect nipple as she came in his arms. He felt Tina’s canal squeeze down on his cock, pumping in miraculous harmony with his own ejaculations. His seed shot even harder inside her as their bodies shook in perfect sync.

Lisa, Dixie Clemets and Candy Cane watched with wide-eyed wonder as Ryu staggered over to fall back onto the examination table with Tina on top of him. Ryu and Tina gasped for air, their bodies still quivering from residual pleasure. Finally Ryu realized something had happened.

“It has stopped.” He said, breathing deeply. His cock was still hard and throbbing with readiness inside Tina, but his orgasm had finally concluded.

“Damn.” Tina cursed, snapping her fingers before brushing her blond hair from her eyes as she lay on Ryu’s chest. She gave him a wink. “I could have done that forever.”

“I see.” Lisa spoke over the intercom, reviewing the last few minutes of data on her screen. “It seems that Tina’s orgasm was what triggered the end. I would guess that Bayonetta’s spell ensures that Ryu’s partner will experience a simultaneous orgasm.”

“I’m really beginning to like this Bayonetta.” Tina giggled before giving Ryu a long, sensuous kiss.

“There was never any sign that Ryu would have run out of semen.” Lisa continued. “It would seem, Ryu, that you can produce whatever amount of semen is necessary given any situation.”

“What I wouldn’t give to get in there with them.” Candy Cane lightly slapped Dixie’s thigh.

“I hear ya, darlin’.” Dixie nodded, her right hand still gently fondling Candy’s right breast. “There they go again!”

Tina sat up and began bouncing atop Ryu’s loins once again, reaching up and groping her massive breasts while the ninja ran his hands over her sculpted thighs.

“Patience, you two.” Lisa fondly chided Dixie and Candy. “Say, how is Anesthesia? I haven’t seen her since Yasha took her to meet with Fujiko.”

“She’s fine.” Candy said with a mischievous twinkle in her eyes. “More than fine, actually.”

“What? What happened?” Lisa asked, suddenly intrigued enough to tear her eyes from Tina’s luscious butt.

“Well now…” Candy said. “This is quite a story…”
