Thank you for all the reviews, this is the final installment for this story. This one is a doozy and I claim no credit for it, it was written entiretl7 by sakurablossomhime as a challenge fic and she really lived up to it :)

Enjoy!

He should have known better by now.

This was exactly why he was as tense as…as he had nothing to compare it to and simply opted to sit silently, stony on the couch with his face covered while his wife bounced, chirped, overall grated his already frayed nerves.

Hindsight was always 20/20, especially if one was watching for the results of a pregnancy test…for themselves.

Tseng had just walked into his open concept home on several acres in Edge. Training had been especially difficult since Rhys had decided to be an ass of himself. Apparently, there was one moron in each generation and they tended to have names that started with the letter 'R'. He'd shoulder that shit to Reno, see how he liked dealing with himself.

He pinched the bridge of his nose and sighed away his annoyance since he was in his peaceful, two story domicile.

It also seemed like his wife was not there. Yes, he clearly was a glutton for pain even on the home front, eloping with the very real Empress of Wutai, of their homeland.

He was technically the Emperor of the very country that had given him away because of his old affiliation with Shinra Power Company. That was when it meant something different…something adverse and evil at the time.

Now Rufus Shinra and Cloud Strife acted like a monarchy of sorts with the birth of the World Regenesis Organization, or WRO abbreviated. Rufus was Queen to Cloud's Kingly rule. He kept Rufus out of old habits inculcated by his father and helped with Iliad and Sonnet Strife-Shinra, their son and daughter.

That was so odd to say: Rufus Shinra and Cloud Strife's children.

Sephiroth and Tifa had welcome their own daughter just over a year ago, starting off this new little trend.

She was a beautiful child as well.

So was his old employer's children. Such a shock of blonde hairs and blue eyes. It wasn't unexpected, just that they had Cloud's forever baby face. The fact that Yuffie had peddled her 'wares' at Rufus and had survived. Second shock was back to Cloud Strife. He'd been drifting until a beautiful crossing dressing Rufus Shinra wined and dined him and stole his heart, he seemed…content. When it was revealed Rufus Shinra was now pregnant with Cloud Strife's children, he seemed unfazed. He even married Rufus. When asked later why Rufus had did it, he'd admitted that he was shockingly more comfortable as a female but had dreaded the gender reassignment surgery. The Materia gave him his life to actually remain bisexual, leaning towards the same sex more.

Those infernal Materia got around. Even Vincent Valentine and Reeve Tuesti who had been in a relationship with each other since Omega Crisis had tried them, liking the other side of the sex of homosexual females. Them writhing around and rubbing their womanhoods together like exotic butterflies mating…was very arousing. Who even knew Vincent could make that amount of sounds and blush and Reeve a dropped dead beauty under the bearded, chiseled man. These scenes were all on video tape like the other couple's mating's. Infringing on privacy…sure, but it all made for excellent stimulus for him and the Missus.

Tseng had been genuinely amused by the errant pregnancies. This is why Yuffie Kisaragi-Xu could have all the fun she wanted as 'Sai', why he remained a male. He had been bisexual forever and was no blushing violet when it came to sex with a woman or man. Yuffie liked it, he was fond of it, it all worked.

Tseng was taking his tie off and his fingerless gloves as he unarmed himself.

He had worked open his button up shirt when he heard it: giggling.

Tseng froze with his shirt open, his gun holster just pulled from his body. He knew now he wasn't alone.

"Yuffie come out. I do not want to play right now; I am exhausted" Tseng said to his mischievous wife as he bodily turned towards the sound with his arms across his chest.

Yuffie stepped out the shadows of the foyer from an adjacent hall. The place was huge, more than needed sometimes.

"Yuffie what are you scheming? Tseng walked up to her and loomed over her, awaiting an answer.

Playing coy, Yuffie spoke with her hands behind her back clasped all the while she looked down, playing shy.

"I…I was thinking that we would play a new game together" she stated, head still down as she toed the tips of her toes in the area rug below.

Tseng's warnings were all going off but she could be truly nervous to ask him. He knew he could be prickly and cautious to a fault.

"What did you want to play spouse? "Tseng said slowly, breath coming hard for him for some reason.

Something was about to happen.

Though he loomed, he didn't see her own small fingerless gloves on each hand precariously holding something in each hand or the evil smirk the quickly graced her face as she unleashed her attack.

It was when she spoke that Tseng knew he was damned. Snapping her head up she began.

"I was thinking seeking you…and hiding a piece of me in your female form" and with the reflexes that made her a ninja, that horrifying, warming, and exciting orb was pressed against his forehead right where his tilak was, causing him to cross his eyes trying to see the unknown damage he had no hope of viewing.

He felt his body absorb it and saw through his immediate malaise, her push the other absorbed into her own mid drift.

Yuffie more or less collapsed where she stood in a heap as the change overtook her.

Due to Tseng's training against poisoning and sleeping implements, Tseng staggered to Yuffie then with his sheer will laid her in one the guest rooms. He hated he cared even after she had explicitly gone against him.

Tseng came back from the room afraid and now exhausted to passing out, which he did in the living room chair in the first living area. The last conscious though was how he'd be damned if 'Sai', Yuffie's alter ego touched his female form. He would weather this storm.

Tseng was the first to recover from the Materia's effects. He swiftly stood on guard against 'Sai' but 'she' almost lost 'her' footing due to different center of gravity.

There, on his now heaving chest bared slightly in the now comically big shirt, laid two medium sized breast tipped with taupe nipples.

Tseng grabbed either side of the shirt and just stared. 'Her' hair draped over a shoulder and the rest along her back as a heavy curtain touching the cheeks of her bottom, as all aspects were taken in and pants rode dangerously low on the new waist.

There was a shuffling causing Tseng to look up. There stood Yuffie, 'Sai' in male form practically violating 'her' with 'his' eyes.

"Ugh, I knew it, GAWD! Yuri you look good enough…to eat" Sai said that last part with a deep timbre that had the newly dubbed Yuri taking off in a run.

It was difficult to say the least with the new additions on his chest and also height difference, him now being a 5'4 ft. instead of the 6'0 ft. man he had been since the end of puberty. Sai was gaining because of his own clumsiness and almost tripping on the pants…and boxers that were barely there. With a sigh and also with self-preservation kicking in, she quickly shucked the bottoms, leaving her exposed to the world in the front and a hint of privacy from behind between his hair swaying as he ran and the ridiculously long white work shirt.

Sai teased. He knew he could have caught her at any time due to her clothing hang-ups and also simply now body mechanics. Yuffie internally would be lying if she didn't find the jiggling, unbound breast and bouncing, softly curved bubbly cheeks of Tseng's ass now hypnotizing.

'Yuri' ran around the house like a doomed prey. The more she ran, the more the infernal side effect of arousal played with her sense as the Materia did cause instant ovulation.

NO! She wouldn't go down without a fight, no matter how much more handsome 'Sai' looked in this form to her.

Sai was on fire! He had to have her! He had been playing around and letting her get away and he was about to bust. Play time was over.

Yuri had taken a hard turn into the master bedroom and decided it was a wonderful idea to head for the private garden out back. The backyard was lush and the privacy great as the grounds were large. Yuri was tiring and also agitated. As she ran, her shirt bellowing in the breeze showing all of what laid below, she tripped on a tree root and went down arms out straight with an angry, cursing yowl.

She flipped over to bound back up despite her scratches and superficial cuts.

Just as she made to crouch, a familiar yet unfamiliar weight settled on her pert bottom. The weight shifted and started to spread out evenly and ending with deep huffs of breath into her hair. Just as a withering statement was about to be released from the coined named Yuri's mouth, questing lips began to map along the path from one of her ears to pepper kisses along her lithe and pale neck.

Tseng's subconscious stuttered. It made him aroused more and angrier all at the same time. She started to speak again.

"No, Sai get off of me this instant. You know my rules" she said in the most authoritive voice, one with a bell like quality could have.

Yuffie, Sai groaned against the writhing body that was trying to claw from under the heavier weight, as her body remained cloaked in that wonderfully useless white shirt and her stomach was pressed into the soft and hardy grass outside under the high sun as the breeze blew both counterparts hair and long their skin.

"Please Tseng! You are killing me with this new body of yours. I…I know the risk. I will even wear a condom okay, I just gotta have you and in this form. You have no idea what you are doing to me even with your same cold prick attitude" Yuffie said grinding gently into the plush derrière below, causing Tseng's train of thought to scatter.

"Yuffie…" Tseng muttered as she was flipped over and the incessant kisses along her ear and neck continued as she fought the mounting desire.

Yuffie pulled back and just took in the mouthwatering visual Tseng painted.

Tseng laid cushioned on the plush grass.

Too long of sleeves covered her hands where they were kept at her sides with the slightest hint of small fingers with naturally oval nails peeking out. The white work shirt had parted to display creamy breast that shown as living ivory in the sun topped with light taupe nipples. The long and lean legs were bent at the knees where the legs met to hide her womanhood, while her once fitted dress socks drooped from right under her knees where the bunched in on themselves. She looked away from Yuffie's hungry gaze with an embarrassed blush on her face as her hair pooled in dark chocolate spools below her head with eyes showing hazel with flecks of gold in them from the sunlight bathing her body.

'Sai' almost came at the vision before him. He'd known that Tseng made a beautiful but stoic man. How much more so gorgeous when turned into a female she had lovingly named Yuri. 'Sai' knew he would have her, even if it took some coercion.

Yuri snapped her face up to look at the now bare Sai, all the while blinking against the sunlight hitting her eyes, her thick and dark eyelashes brushing barely there freckles high on her cheeks, her tilak still present in this form still marking who she really was and her widow's peak flowing back into dark depths of silken strands.

Sai again placed his weight along her.

"I do not see a condom on you. In fact, I see entirely too much of your male form right now. Your matter of body status is also not wanted" Yuri said in a sweet sounding but severe voice, all Tseng underneath as she took in Sai's excitement of the situation.

Sai lowered down again and with both hands gently parted Yuri's legs. Tseng's subconscious still wanted to choose to fight.

Sai laid along her, his need pressing the inside of her thigh.

Yuri's flush began creeping along her body. Despite the risk Tseng knew was there from using the Materia, some sick part of him wanted, no needed to feel this from Yuffie. He truly hated his weakness for all things her.

Nipping from a delicate ear lobe to her clavicle, Sai took his time with the body beneath him. Yuffie knew in her mind she would win; it was just a matter of pressing the right buttons. After all, that was what had gotten her Tseng in the first place. She would wear him down and then wear him out.

Yuri stubbornly tried to muffle the sounds her mouth wanted to make just from the simple movements that Sai was doing to her. She hated it, loved it, and feared it all in one. Just as she was certain she could keep up her walls and feign indifference, Sai took one of those dusty rose nubs into his hot mouth.

Yuri actually yelped in her surprised enjoyment of the feeling and immediately darkened three different shades of pink.

Sai smiled against the hardened nipple and treated the other to the same loving care as Yuri squirmed to get away from the treacherous mouth, inadvertently rubbing along Sai in a very intimate area with each move, causing him to moan into the fleshy nip in his mouth and that set off a moan from Yuri as well.

Yuri's hands shot up to Sai arms on the sides of her head, her fingernails digging into the skin.

Sai understood now. Yuri's breast was very sensitive. He didn't know it was enough for her to orgasm to while he now groped and massaged them while he happily nursed away.

Yuri grit her teeth at the onslaught of feelings that seemed to shoot straight from her painfully sensitive, highly aroused nipples straight to below her navel. Tseng's mind fleeted about, so revved up that it felt as though he was about to come-just from his chest being fondled.

That ball of tension in her lower abdomen had been tightening as Sai had rubbed along her sides and back to her breast. With the last of Tseng's conscious understanding what this was, he as Yuri did indeed come.

Yuri cried out brokenly and her legs attempted to slam shut. Since Sai was her middle, she writhed deliciously against him.

Yuri hated that she had come so easily and with very little effort on Sai's end who was currently smirking irritatingly at her body's response. She swore she'd fight harder. Sai needed to know that no meant no. If only she could convince her traitorous body that.

Sai saw Yuri going stony even as whispers of muscles clenching and relaxing in her abdomen slowed from her coming.

It was like that huh? Sai always loved a challenge.

With a strength eclipsed by the small and lithe frame, Sai pulled Yuri to him with her emitting an indignant squawk and Wutaian curse in her startling.

"Now, now there's no need to curse Yuri, but you may feel the need to as I show you another form of pleasure" Sai stated.

Yuri stilled. She began trying to pull away but found herself with an arm along her waist…and a prodding tongue at her clitoris.

Yuri cried out, her hair looking more tussled, eyes closed and her beginning to shake badly as Sai worked her special place over with tongue and a slight grazing of teeth over the clitoral hood. Within no time, Yuri held Sai against her flower with both of her hands, eyes cracked but glazed in the heat of passion, her right thigh shaking badly. With one last swirl along her lovely button, she stiffened and with a shriek, she came hard, pinning Sai's head with her thighs on either side.

She slowly disentangled from his head as she slumped backwards into the grass.

Sai felt like he would bust. Yuri looked so depraved, the shirt had now slipped all the way down to pool at her wrist and hands, her chest rising and falling rapidly with closed eyes.

Sai couldn't wait anymore. He slid against her bottom, causing her lust filled eyes to snap open with slight fear. She could now admit that this had been worth it but Sai still didn't wear a condom. While Tseng was not as augmented as Sephiroth, he had been exposed to Jenova cells and Mako. What if he caught on this tryst?

He'd laughed at the others. Was he strong enough should he be the next "pregnant male"?

Those same reoccurring thoughts were washed from his mind in a hot and demanding kiss.

Just as Yuri had her wits about her again, Sai had positioned himself and thrust into her.

Sai screamed out in genuine pain. Sai realized that despite Tseng having been sexually active, this side of him-had been a virgin.

Just as Sai realized that he was breaching a hymen, he went stock still and looked stricken.

"Oh Leviathan! Why would any female go through this pain?" Yuri swallowed thickly trying not to honestly throw up at the shooting pain that seemed so acute. She began to draw in on herself, her arms covering her breast and her thighs holding onto Sai's hips like a lifeline in the hopes to scissor him in half to just close them firmly.

Yuffie mentally felt ill and repulsed by her actions. Tseng had been a genuine gentleman once she had conceded to date him for the sake of her dynasty. She'd had hated it, thinking that Vincent would come around but he never did. He saw too much of a ghost of Lucrecia Crescent in Shelke Rui. . .

Tseng had treated her like a lady though she'd been nothing less than hostile to him in the beginning. But then along the way she really noticed him. His beauty, his strength, and his intelligence. His dry humor finally made an appearance and that was what really caused them to hit it off. So when it came time to actually marry him, she couldn't complain. And oh GAWD when he'd had her body for the first time. It was everything she'd wanted. He'd been meticulous in his foreplay to ensure that she was excited. He'd saw her off at least four or five times before he had even entered into her. Oh but when he did, he covered her with his body, one arm under her and the other resting by her head, his hand tangled into her hair and he swallowed each and every cry, squeal, and moan she emitted from her mouth into his own as his gyrated and pounded into her depths.

Tseng's mind finally stopped reeling from the internal tearing. He would have thought that with him having been being sexually active that was impossible for him to be a virgin in either form but somehow it had been. He flexed the strange and new muscles around Sai's appendage that remained embedded deep inside his feminine body. While it was still sore, looking into Sai's face, Yuri saw guilt and she didn't like it. Neither of them could have known that would be the case with her. Yuri weakly bucked up against Sai getting all of his attention and a groan of pleasure.

Sai looked down at Yuri and saw the same love and understanding that the male version held for him.

"You have been badgering me forever to get me into this position. Tell me this is the best you can do?" Yuri secretly urged Sai to action because unbeknownst to him, Sai had rubbed something internally that had felt heavenly and had taken the throbbing down several notches.

Seeing that Yuri still wanted to, Sai drew out to the head of his penis remained in her, and thrust back in.

The feeling was immediate and Yuri moaned for a whole different reason. Yes, she was filled to bursting it felt but the bulbous head of Sai's penis had passed something inside her so wonderfully, she mewled out, causing her to instantly blush and try to shut down her face.

Sai is not having it. He heard that response to that movement. Focusing on her face, he sets up a steady rhythm, making sure to keep his angle he had.

This time Yuri did arch off the bed blushing deeply while crying out and moaning with each passing over that area. Tseng's subconscious supplied that it was more than likely his g-spot. No wonder Yuffie would be all over him.

Yuri touched Sai's shoulders and grabbed with her fingers. She was quickly building towards something, something that threaten to take her breath and sanity with it. She braced one hand back on her lower stomach, lifting up slightly to see where her breast bounced and jiggle and further down where they connected over and over again.

The tightening in her released with those visions in her mind, her coming with a screaming wail it was so intense from the visual stimulus that appealed to her very male subconscious and what Sai was doing to her body below with his own.

She was pulled into his lap and she made aware that Sai hadn't fell over the precipice of passion and remained hard.

Sai felt her coming around him like a thousand moon moths flying out into the sky. He staves off his end but just barely. He wanted every angle of her before he gave in. His stubbornness demanding it.

He gathered the woman into his lap onto him and began bouncing her upon his need. A sob left Yuri's mouth as Sai began moving her body again along his length. Everything was still so sensitive and in this position she could feel even more of him. Her head lulled back as she was manually moved and a steady stream of moans mixed with Wutaian slipped from her perfect lips. Her little hands were balled against Sai's chest as her eyes were glistening with unwashed tears even as she wore a permanent dark blush and her eyes were half mast. Sai picked up the pace and just as before her orgasm took Yuri, having her wrap her arms around his wide shoulders and back and dig in leaving ten perfectly shaped crescent moon shapes in their wake.

Yuri was so tired. Surely Sai was done.

Sai still out stubbornness hadn't come. He had to have her in one final way as his own energy was waning but he wanted to leave a lasting impression.

He gently de-attached Yuri and flipped her onto her arms and hands with her hips high and separated. Before Yuri could really question what was going on, Sai was back within her physically scooting her along the moss with the force.

Yuri's arms gave out immediately. She could feel everything. Every nuance, every vein, the very flare if the head of his penis as his set a brutal pace within her this time.

Each exhale was a moan while each inhale was a cry. She extended her arms in front of her tilling the soft moss with her nails she had no idea what to do with her hands. Each thrust made all that chocolate hair ripple as if it was a living entity. She lifted her face with slacken mouth to the sky and with a build up of swears in Wutaian in pitch, it at all ended in a high pitched wail as she clamped down hard on Sai earning his climax as well which set off another lesser one that she could only writhe and moan at as Sai finally claimed her lips.

Yuri…Tseng was the perfect picture of debauchery. Her face was beet red and covered in sweat and tears. She had a small path of drool coming from her mouth, and her eyes had completely clouded over to a dark chocolate, almost actually jet black as she heaved to catch her breath.

Yuffie felt a swelling of pride at her handy work.

She gently lifted the rag doll like Yuri and took her into their suite. Their she wiped her down and washed her of any dirt or grass or other fluids that remained and tucked her into bed until the Materia wore off.

Tseng woke the following day completely nude and tangled in the covers complete with bird's nest hair. He knew he'd have to face a gloating Yuffie…about yesterday. He had no idea what else was in store.

It had come to one Vincent Valentine's attention (via an overly hyper overshare from Yuffie Kisaragi in her post haze from the day before), that everyone's love making had been viewed, well everyone still at the WRO or close to the organization. That meant Rufus Shinra, Cloud Strife, Sephiroth Crescent-Valentine, Tifa Crescent-Valentine, and Reeve Tuesti and himself were on the menu. Vincent put his old TURK mentality to work and soon he had what he wanted. This was only fair if they had pried into their personal lives.

Tseng had come to the office to an odd meeting of the aforementioned people, including Reno with his husband and their daughter, the tiny tot sporting a shock of red hair that gave no doubt as to who her "mother" was…and Yuffie. He had a horrible feeling about this bit wouldn't deny his employers Rufus or Reeve.

Once in the room, he took note of the attendees and of Yuffie's guilty pleading face. He had a good idea what this was about and was turning pale quickly, but maintained his neutral face. When he looked at Vincent Valentine, more or less glare death at him as he started this whatever, it was with no remorsefulness as he sat by Reeve, he knew what it was.

They had been found out.

The video started with what had caused an ill-fitting clothed Tseng to take flight that quickly turned to just a white shirt to run from male Yuffie as a female. At the end it was wrapping with his thoroughly fucked face on a female's body, not to mention what he had said in Wutaian was understood by Rufus, Sephiroth, and definitely Vincent Valentine, asshole extraordinaire.

His face burned with the activities on the screen and he never once took his eyes off of it, as if it never affected him at all, well if you didn't see the minute frown and blush.

Rufus simply stood up and curiously adjusted himself and went to the podium.

"We are aware of your "past time" fun, we only ask for the same courtesy. After all, that was quite arousing" he said with a purr and something ravenous in those slate blue eyes, that had all the men in attendance, including Tseng himself slightly squirming.

"Meeting adjourned. Everyone will have their own personal copies via email to add to their collections" Rufus said dismissively.

Tseng's mouth actually hung open slightly agape.

The whole lot of them were perverted.

Yuffie looked relived and popped from her seat expecting it was to be something so much worse. Tseng simply glared at her for his exposure.

As he saw the overall room leaving, he didn't miss the hazed over eyes and pronounced areas on the males, some more or less pulling their significant others to find desperate release, namely Sephiroth and a chuckling Tifa.

Tseng simply mused to himself over a cup of much needed black coffee as he continued to look over his paperwork that seemed to have grown in the masses in his absence.

He continued on perfectly unhurried and the perfect picture of stoic as he glanced over at a picture on the corner of his desk.

The display showed a young man doing "bunny ears "over the head of the one in front of him while wearing an enthusiastic smile with one arm around the young woman that stood in front of him bedecked in old world silks holding her burgeoning stomach as she stared head on at the camera, in what seemed to be a tree garden of budding cherry blossoms.

Warm feelings and thoughts connected at the visual and Tseng, despite his normal demeanor felt the heat seeping into his face again at their first time (and subsequent times) in reversed roles looking on at the picture that he normally could stay disconnected to a fault from.

He was roused from his thoughts from the slight noise by the bottom of his desk. He held his cup of coffee in both hands and looked downwards at the disgruntled sight. There laid proof of their coupling (and his private downfall) squirming and fussing with her little dark head covered in her Moogle knit cap and her body in the matching jumper.

His severe look softened immediately and he gently started the floor rocker with the tip of one polished shoe gently as she lulled to sleep once again, gently sucking on her thumb.

He stared on a bit more amazed at the child that had come from him and finally with all the temperament of a new mother, tore his eyes away from the child and went back to work awaiting his wife's arrival from her mission.
