A few months ago, the Great Change caused 15% of humanity to become partially animal. People all over the world gained features for animals, ranging from horse to butterfly, through the unexplained transformations. Society was forced to adapt as celebrities, politicians, parents, and even children transformed and needed special accommodations.

The area where society proved least adaptable was the Changed people's sex lives. The prudish public refused to approach the topic and people suffered as a result. Even the couples who visited doctors and sought out creative solutions on their own ran into a new problem eventually: mating season.

Estrus, rutting season, being in heat. There are many words for mating seasons but the effect is largely the same: at certain times of year, the animal gets uncontrollably aroused and literally needs sex. For Changed people this was incredibly disruptive, requiring people to take time off work, or in some cases, driving them to extreme behavior to find sexual relief.

During Serah's estrus, she was beyond horny. She had to call out of work because she was wet and aroused all day. Every waking instant was like torture, with every cell in her body crying out. She tried to satisfy herself through masterbation, but it wasn't enough.

The second Shoto got home from work, she literally begged, “Fuck me, Shoto. I need it. I need your cock and every toy in the house in me! Maybe that will let me come and end this nightmare."

Shoto wanted to make a quip about the word night-'mare' and thought better of it. Serah was normally receptive to his dumb jokes, even at her expense, but she was not in a normal mood. Every instant she wasn't having sex, she was annoyed or even angry. And sex was its own exercise in frustrating futility: she hadn't been able to orgasm for two weeks, despite trying several times every day.

Shoto was chugging protein shakes and vitamins like mad, trying to keep up with his ravenous centaur girlfriend, but it was starting to take a toll on him. Already, Serah had bruised his thighs when she'd dropped her full weight on him in a moment of missed-orgasm despair. If that happened again in a way that hurt his dick, it was all over. He was worried about whether their relationship could withstand the stress that Serah's estrus was putting on it.

Shoto took a long, slow breath, then said, “Serah, I have an idea that should help you. But it's a bit unusual."

“Oh? What is it?" She was struggling mightily to act only mildly interested. Under the surface she was boiling with desire and nervous energy.

“We haven't tried anal. Maybe three points of contact will be enough to get you off."

Serah nodded. Of course she'd thought of that days ago, but she had been worried that Shoto would be grossed out and she knew that she couldn't reach her ass by herself.

Shoto said, “The way I see it, we could attach a dildo to a wall to use on your butt, but that seems really tricky…" Shoto was thinking that Serah's size and lack of visibility would be too prohibitive.

Serah nodded again, slowly. She'd actually tried that herself while Shoto was at work but she'd been unable get the positioning right. With every drop of her willpower, she calmly said, “Yeah, that doesn't seem like it'd work."

“Or I can be in the back. I don't know if that weirds you out but I'm willing it try it if you are." He blushed a little and broke eye contact, then said, “I think it could be fun…"

Serah's eyes lit up and her mouth started to water. She'd been worried for nothing. “We have a deal. Get back there," she said with surprising force. She was already stripping off her clothes, not that she was wearing much. With her heat in effect, anything pressing on her crotch or nipples was torture.

While Shoto clumsily undressed, Serah plugged the toy they'd nicknamed the “Big One" into the remote control outlet, which was currently powered off. All the lower settings were worthless when she was in this state so she flipped the toy to its max setting in preparation. She took the remote in one hand and her favorite regular rabbit vibe in the other.

Without waiting for Shoto, she climbed on the bed, turn turned the smaller vibrator on and slipped it in. As soon as he gets his lazy ass in gear and gets the Big One in me, I'm turning it on and grabbing my tits. It isn't as good as when Shoto sucks on 'em, but beggars can't be choosers.

“Uh, I was thinking I'd use a condom, for cleanliness reasons," Shoto said cautiously.

“Sure, whatever. Just get in me already," Serah snapped. Then with a bit more restraint, she added, “Actually, put the Big One in first."

Shoto grabbed the toy and lined it up with her gaping and dripping pussy. The size of that toy always made him feel inadequate but he knew that no human cock, not even a pornstar's, was going to satisfy Serah's horse-sized slit.

He pushed the massive rubber cock into Serah but before he could even get the rabbit part lined up with her clit, she turned it on. On its max setting, it was like trying to hold a live wire and his hands quickly started to tingle. If he didn't get it lined up soon, they'd go numb.

Thankfully, he got it aligned and gave it a solid push into place. It stopped only when the rabbit's base hit her mound. Her cervix must have been deeper still. Maybe that's part of her problem, he thought. When she's this aroused, her cervix moves too far back

The toy was slightly thinner just before the base than it was around the center so it stayed inside Serah without help. While that feature was normally very necessary, since neither of them could reach it in their standard positions, this time Shoto would be back there to realign it as needed. But first, he had something else to do.

With shaking hands, he opened a condom wrapper and slid the condom on his very erect dick. The idea of finally trying anal had him aroused, and Serah's eagerness was a major turn-on too Then he gently pulled Serah's new brunette tail out of the way.

“Mmm," Serah moaned at the slight tug. “Do more of that, once you're in."

“You got it," Shoto replied distractedly. His eyes were glued to his goal: the round and puckered entrance of Serah's ass, just above the stuffed and vibrating chasm of her pussy. He started to line himself up with it but he remembered something important: unlike her pussy, which was slick 24/7 lately, her ass needed lube.

He grabbed a bottle of lube and squirted some directly on his wrapped dick. He thought it might be too much, but he'd heard that more was better in these cases. He spread it around with one hand then wiped the hand off on the towel they'd already placed on the bed.

Wrapped and lubed and ready to go, Shoto finally pressed the tip of his cock to the ring of Serah's asshole. She twitched at the cold sensation then lifted her butt into it. He knew her large horse anatomy could handle much bigger than him, but it was hard to overcome the desire to take it safe and slow. What she said next helped.

“Stick it in me, Shoto. I know you've wanted this since you stared at it when you first put the Big One in me. My ass wants your cock just as much, if not more." She turned her upper body around to look him in the eye. When he finally met her gaze, she added, “And I know I've been a bitch lately because of this estrus, but I really love you."

“I love you too," he replied, then he pushed it inside.

It was tight. Tighter than he'd expected, but just because her ass was big didn't mean it had to be loose. And it felt great. He could even feel the Big One's vibrations through Serah's body. He thanked god that the condom was dampening the sensations a bit or he might have gone off early.

“OOooh," Serah moaned. “You feel so big, Shoto."

That was exactly what Shoto needed to hear after his humbling comparison to the Big One. With that erotic thought fanning his flames, he started to thrust. He slid the length of his cock in and out in measured movements, using the slight bulge of his cockhead as a guideline, stopping just before slipping out. All the while, he could feel the tense tightness of her ass squeezing down on him.

Once he got into a rhythm, he was able to focus on the task at hand: getting Serah off by any means necessary. And his current 'means' included his two free hands. He grabbed her tail near the base and gave a testing tug.

“Yes, yes!" Serah called out, She was looking away but her whole upper body was flushed with excitement. She had one hand on her vibrator, grinding it into her human pussy, and the other on her right breast. Her breasts were normally modest C cups but since estrus had hit they'd swollen to Ds or even Es.

And the nipples had gotten sensitive. She was pinching one lightly between her fingers and rolling in gently, yet the sensation was nearly enough to be painful. She pressed down against her chest and found that the breast itself had also gotten touchy in a way that felt simultaneously uncomfortable and amazing.

Meanwhile, Shoto had hit a groove and was capitalizing on it. The thought of fucking his girlfriend in the ass while a genuinely massive dildo filled her pussy was enough to keep his engines running at full blast. But adding the fact that she had another dildo in her other pussy and she was going wild on her breasts… that had sent him straight to heaven.

He tugged her tail in time with each thrust and grabbed her flank with his other hand. She had soft brown fur all over her lower body and he really loved to touch it, but Serah was embarrassed and usually kept it covered up. He started to massage her hip in wide, circular motions, until he noticed something interesting: each time he got near her ass, she tightened down delightfully on his cock.

With that in mind, Shoto's hand migrated further back until his thumb made a teasing pass right near Serah's occupied asshole. As he'd suspected, each brush sent her sphincter muscles into tiny adorable spasms. He was worried that it might be too distracting for Serah, until she mumbled to keep going.

“You got it, honey," he said as he switched focus a bit. He aligned all of his activities onto a single cadence, timing everything along with his thrusts. On each plunge, he tugged her tail up and away and slid his thumb on one side of her ass and his index finger along the other. He was even able to stack his hands so they moved together like a totem pole of synchronized sexual pleasure.

“Yes, c'mon, fuck, yes!" Serah called out with increasing volume as she got closer to orgasm than she'd been in weeks. “Harder, Shoto. Fuck me hard."

As commanded, he pulled back as far as he could and slammed balls-deep back in. In fact, his balls slapped hard against her taint in a way that he enjoyed in the heat of the moment but would likely regret later. They were also touching the base of the furiously vibrating Big One so staying there wasn't an option. Not that he wanted to. He wanted to thrust harder and faster until Serah came so hard that this estrus nightmare was blown out of her body like an exorcised demon.

Again and again he pulled back and slammed in, smashing his hips against her firm and muscular flank. There was no room for his hands in that melee so he kept one on her tail and withdrew the other. Then in a spur of the moment decision, he winded it back and slapped her on the flank, hard.

Every muscle in Serah's body clenched in surprise. It was very lucky that she was kneeling on all four knees, because her back legs tried to kick. Instead, she just bucked up a bit, pushing Shoto even harder against her punished ass.

That pushed him over the edge and he couldn't hold it in any longer. “I'm gonna come, Serah. I'm cumming in your ass!" With that warning, he bottomed out inside her, grabbed tightly into the meat of her flank with both hands, and let loose.

His mind went white as blast after blast pumped out of him, flooding his body with endorphins and filling the condom with cum. On some faint level of consciousness, far removed from reality, he wished that he hadn't used a condom so he could have painted her insides with his seed.

Fortunately, the mental and physical stimulation of Shoto's frantic orgasm, along with the veritable assault on nearly every erogenous zone on Serah's body, finally got her off. Like being shoved from behind over a massive chasm, she cleared the previously impassable gap and fell into the absolute bliss of orgasm. “Fuck yes!" she screamed in celebration.

At first, it was a normal orgasm, with wonderful endorphins crashing into her mind and body, flavoring every sensation with delicious pleasure. Then it doubled in intensity, then doubled again, and it kept growing. It was as if every orgasm she'd been denied throughout her estrus had dropped on her all at once. Her mind would go blank from pure overstimulation, only to be pulled back down to reality by the incessant electric jolts of pleasure on every front.

Her stomach buckled as her abs clenched tight, forcing her to let go of her breast and vibrator to hold herself up. With both palms on the bed, she leaned forward, panting for breath, her long brunette hair falling in her face. It tickled her nose but that didn't even register. There were dozens of other sensations fighting for her attention that were stronger by orders of magnitude.

Not the strongest sensation by a longshot, but the most in her control, was the vibrator currently wedged all the way into her front pussy and cranked to max settings. Part of her wanted to turn it off, to get it out and silence at least one of the many tantalizing torturers that were battering her frazzled nervous system. But another part of her wanted to cram that vibrator in harder, to grind on it and keep this tsunami of stimulation going forever. That part won out, at least temporarily.

Serah fell further forward until her upper body was propped up on her right forearm and elbow, then she maneuvered her left hand back between her front legs. She'd thought that the vibrator was as far in as it could go, pressed by the bed and her body, but it turns out there was a bit of leeway yet. She slipped her hand under it, palm up, then lifted it with three fingers. It contacted two points simultaneously: her clitoris, via the external 'rabbit' part of the vibrator, and her cervix, which had been pushed down closer by her crunched position.

While some women found even the slightest contact on their cervix uncomfortable or even painful, other women found it pleasurable. Serah was very much in the second camp. She loved vibrations deep inside herself, directly on her cervix, even if it usually meant soreness for a day or two afterwards. In her current state of continuous orgasm, that direct contact was beyond her expectations.

The instant the vibrator touched that bundle of nerves at the entrance to her womb, they went wild. Her stomach clenched tighter, her front legs spasmed, and her breath caught in her throat. She moaned into the bedspread, then bit it in her teeth while she rode out the never ending hurricane of orgasmic bliss.

Meanwhile, Shoto was running out of steam. Weeks of twice-daily (or more) sex had taken a lot out of him physically and everything about the stressful estrus situation had taken a toll on his mental state. His dick was still hard enough to thrust into Serah's ass, dragging a ballooned condom along with it, but his hips were screaming with an aching pain and his thighs were starting to cramp.

“I'm sorry, Serah, but I'm done," he said as he fell backward onto his heels, pulling out on the way. The very full condom was thankfully still in place so he went to reach for a tissue to clean up, but he stopped partway.

Before him was a frantically orgasming woman, her vibrator-stuffed pussy on broad display. He quickly discovered that while his body was no longer capable of sex, his mind was still very much willing. He got hard again, painfully so, but finished getting a tissue to throw the condom away. After that was done, he laid on his side and propped his head up with one arm, and quietly watched his lovely girlfriend experiencing pure bliss.

Thirty seconds, then a minute, then two; Serah just kept cumming. While she had needed anal sex to get the party started, now that the doors were open, the two vibrators were more than enough to keep the celebration rolling. Like a burst dam letting loose its entire contents, there was no stopping the wave after wave of orgasms crashing upon her. Shoto sat back and enjoyed the show as a passive audience, but Serah was smack in the middle of it.

On some level she knew Shoto had pulled out. Fainter still she thought he was watching her, but she was lost in the physical sensation of yet another orgasm. That was assuming that it even was a different orgasm. She couldn't know for sure where one ended and the next began. All she did know is that she was approaching her limits, both mentally and physically.

Her horse parts seemed to have a higher tolerance than her human ones and soon her front pussy was getting twitchy and irritated from overstimulation. With the last of her conscious effort, she flipped that vibrator off. Then, with it and the active Big One still in her, she flopped forward and passed out, her lower body still upright and her ass still in the air.

“Uh, Serah?" Shoto called out. At first, he thought it was just another step on her orgasmic journey but he quickly realized she was asleep. “I should turn the Big One off," he mumbled to himself as he looked for the remote. It was nowhere in sight so he guessed it was stuck under Serah somewhere, or tossed away in a moment of ecstasy.

Rather than keep searching fruitlessly, he reluctantly rose from the bed. His hip joints cried rebelliously as he walked over and unplugged the toy from the wall entirely. The Big One rumbled to a stop and the room became eerily silent. He'd grown used to the low buzz of both vibrators and the rapid breathing of two lovers in action, not to mention the wet slapping of body on body. But now the only sound was the slow breath of his sleeping darling.

Should I take it out of her? he wondered. It might be bad to stay stretched out for too long, and her body needs to recover, I think. With that decided, Shoto grabbed the hefty base of the toy and tugged. Because of the tapered effect near the base, it took an unexpected amount of force to get the large dildo free of her clasping vagina. But he managed.

It popped loose with a lewd SLUPP and a flood of juices followed after, soaking the intelligently placed towel below Serah's hindquarters. Shoto found his gaze entranced by the sight of Serah's gaping pussy, which was slowly contracting again. Even as it closed, it would easily fit his hand. His penis would have barely registered inside it.

He felt a twinge of sorrow that he would never be able to satisfy that hole, but it faded when he remembered that she had two others that were much better fits. With that wholesome thought, Shoto continued to tend to his sleeping girlfriend, tipping her on her side to get the other dildo out of her. He wiped up some messes, then snuggled up next to her.

They'd both need to get cleaned up properly eventually, but for now he was content to savor the calm moment.
