Chapter 441: Heat(1)[R-18]
Chapter 441: Heat(1)[R-18]
The "estrus" of a beastkin arrives at specific intervals. When it hits, their behavior shifts from the norm.
For instance, they might become more active than usual, sweat profusely, or find themselves unable to tear their eyes away from the opposite sex.
To put it simply, their bodies heat up to a point that becomes difficult to control. During this period, most exert every effort to find some form of release.
Beastkin who haven't found a mate usually resort to masturbation. However, estrus between a married couple can be somewhat troublesome.
It would be ideal if their cycles aligned perfectly, but more often than not, they are out of sync.
Furthermore, the moment they engage in relations while in heat, they exhaust all their physical strength, making it a burden for both the man and the woman.
However, in the case of the half-blood Leona, things were a bit different. Until now, she had mostly managed to pass through her estrus periods without much fuss.
Because her blood was thin as a hybrid, her body rarely heated up to an unbearable degree. At most, perhaps when she first hit puberty?
Moreover, she had developed great patience while hiding her identity and personality, so it never interfered with her daily life.
Even during her time at the Academy, there were no issues. Attendance points weren't that significant, and female students on their periods were given consideration as long as they spoke up.
Thus, Leona had lived a life not much different from a human's even when estrus came—until she met Isaac.
She was turned on. So much so that she wanted to pounce on him right this instant.
He looked somewhat frail due to his feminine features, but that wasn't the case at all once you looked below his neck.
He had an inverted triangle physique forged through exercise. It wasn't bulky like a "muscle pig," but a body of golden proportions.
In particular, his sturdy thighs and the bulge of his "equipment" that occasionally showed through his trousers... were enough to stir Leona's hidden wildness.
It wasn't just that; the scent emanating from him stimulated her sensitive nose.
The scent of lilacs and peaches was fine. But the scent of "nature" was impossible to ignore.
Though she didn't know it, this was thanks to the "Pure Nature's Authority" Isaac had received from Hirt.
It was an authority that made him loved by all "animals" within Hirt's domain. Beastkin possessed animal instincts, and Leona had inherited them, however faintly.
He was already radiating a pheromone-like aura, and on top of that, he had smoked a World Tree Leaf Cigar? And without even ventilating the room?
One could endure it once, but not twice. This was the reason Leona had suddenly lost control.
She had pushed Isaac down with great momentum and even stripped off his underwear, but...
"...... ......"
"Ahem. Ahem."
Seeing a man's genitalia—to use a lewd word, his cock—for the first time in her life, she couldn't help but freeze for a moment.
Suddenly, her mother's words came back to her. Her mother had told her that as a hybrid, she didn't know what might happen, so she should just follow her instincts.
She advised that when it came to the bedroom, if nothing else, Leona should surrender her body to instinct rather than reason.
Throb—
In the meantime, Isaac's member gradually grew until it stood stiff and erect. Though it had been exposed suddenly, Leona's gaze alone was enough to make him aroused.
Leona's eyes trembled at the sight of his member, which boasted a menacing size.
Before the erection, it had been at her eye level, but now it had grown so large she had to tilt her head up.
Was every man's thing this big? Her mother hadn't informed her about this part.
However, her "instinct" told her exactly what to do.
"......Gulp."
She wanted to lick it. She wanted to put that massive thing in her mouth and toy with it to her heart's content.
The scent of the cigar filling the room acted as a sort of aphrodisiac, thoroughly stimulating her instincts.
She couldn't hold back any longer. With an expression that looked half-insane, Leona opened her mouth.
"Haa-um."
"Leo—ngh?!"
Isaac tried to speak to her but ended up letting out a shallow groan. Leona had shoved his member into her mouth without warning.
Because it was so large, only the glans fit, but that was enough for her.
"Haa-um. Slurp. Schlick. Slorp."
After taking it in once, she began to lick it with her tongue as if eating ice cream. She gripped his cock with one hand while fondling her own large breasts with the other.
As a result, the bandages covering her chest slowly unraveled, revealing her bare skin bit by bit.
Perhaps because of the pressure from the bandages, her breasts looked much larger than when she was clothed.
Isaac watched Leona as she greedily sucked on his member without any preamble.
She was so different from the other women he had spent his first nights with. They had started slowly with kisses, but Leona went straight for the cock.
Was this due to the unique wildness of a beastkin? Or was it because of the cigar smoke filling the room?
"Lick. Lick. Blegh."
While he pondered for a moment, Leona drenched Isaac's entire member with her saliva. She had sucked it so much that it was glistening.
It was the grooming behavior common among feline animals. Having that kind of grooming done to his cock made him feel like he was going to ejaculate right then and there.
Even so, she didn't stop. If anything, the more she sucked, the more parched she seemed to become, licking every nook and cranny.
Despite it being her first time, her dazzling skills made Isaac tilt his head back and let out a low groan.
As he did, he placed his hand on her head and gently stroked it.
As if telling her she was doing a good job, encouraging her to be even more proactive.
"Guh."
As if to reward him, Leona took Isaac's massive member into her mouth. About half of the large shaft disappeared.
But she didn't stop there. She began to move her head vigorously up and down.
"Gawk. Slurp. Guck. Gulp."
Every time her head moved up and down, Isaac's cock repeatedly disappeared and reappeared.
Chap-chap-chap-chap—
She moved her hand along the remaining half of the shaft, stimulating the entire cock.
Since it was covered in saliva, lewd sounds filled the room.
A situation where both visual and auditory stimuli were transforming into pleasure. Isaac let out a feverish breath and gripped her head with both hands.
Normally, this would be to help her move more comfortably, but Leona's actions far exceeded his expectations.
Grab—
At that moment, Leona stopped stroking the shaft and grabbed Isaac's hand. The same went for the hand that had been fondling her breast.
Just as Isaac was about to wonder why, Leona used forced strength to pull his hands down.
Normally, she should have stopped halfway, but...
"Le-Leona?"
"Gawk! Nggh...!"
Bit by bit, the shaft of his cock disappeared into Leona's mouth.
"Guh... Nggh..."
She finally swallowed his entire cock. Leona's nose pressed against Isaac's stomach, and his pubic hair tickled her face.
Her eyes rolled back as if she were struggling to breathe, and her face was becoming a mess in real-time.
Isaac, momentarily forgetting the rushing pleasure, marveled at what Leona had done. On their first nights, only Cecile had been able to take his entire cock into her mouth.
That remained true even now. Aside from Cecile, no one else had even thought of swallowing the whole thing.
Squelch— Squelch— Squish—
"Mmph! Ngh! Gawk!"
As if that wasn't impressive enough, Leona didn't stop. Now she was moving her head on her own, ravaging Isaac's cock to her heart's content.
With every movement of her head, his cock repeatedly vanished and reappeared, and Isaac groaned at the overwhelming pleasure.
His throat felt as tight as a pussy. It was a different sensation from when he was with Cecile.
"Gawk! Slurp! Slurp! Schlick!"
As if she had already grown accustomed to it, Leona began to work her tongue. What a lewd woman she was.
Isaac grit his teeth against the approaching climax. At the same time, he pulled Leona's head close.
And then, he let the pent-up ejaculation explode all at once.
Shudder! Spurt! Spurt!
"Mmph?!"
Isaac's semen bypassed her throat and went straight into her stomach. Leona's eyes widened at the strange sensation, and then her body began to tremble.
Inside her mouth, his cock repeatedly contracted and expanded. The semen he had saved up for Leona didn't stop after just one burst.
It gushed out in a long stream as if being squeezed from a container, paused for a moment, and then erupted again.
Isaac held Leona's head for a long time before slowly pulling away. Even as he did, semen continued to leak out bit by bit.
"Sluuuuurp! Pop!"
A lewd sound echoed as the cock was pulled from her mouth. Especially when the glans popped out, he almost shoved it back in.
Soon, Isaac's large cock was fully out, and Leona worked her jaw as if savoring the taste of the remaining semen.
"Gulp. Haa... haa... haa..."
Having finished every last drop of semen, Leona panted with her mouth hanging open.
As if it wasn't enough, she flicked her tongue. Isaac watched her blankly for a moment before smirking and sitting up.
His member was still standing tall and stiff, as if one round wasn't enough.
Thud—
"Ah... ahh..."
Isaac's cock landed with a thud against Leona's face. It was so large it seemed to cover her entire face.
Even while panting, Leona didn't stop moving her tongue. She looked like someone who had nothing left but "beastly" instincts.
However, Isaac had no intention of cruelly granting her wish just yet. Since she had made him go once, shouldn't she be drenched in pleasure as well?
"Do you want it?"
"Ngh. Haah... haah..."
At Isaac's question, Leona momentarily held her breath before nodding fervently. It seemed a shred of reason still remained.
Seeing her body twitching even now, it was clear she was as heated as she could be.
Just a little stimulation would surely drown her in pleasure. Isaac smirked and gave an order.
"Then get on the bed. Our Leona is going to be a good girl, right?"
Isaac stroked Leona's head gently, as if treating a pet rather than a person.
Leona stared at Isaac's cock right in front of her face and nodded vigorously.
She wanted to put this cock in her mouth or her tingling lower mouth right this instant. But to do that, she had to listen to her husband first.
Her husband—no, this male—was much stronger than her. Not her beastkin culture, but her instincts told her so.
Slide—
After taking a contraceptive pill, Isaac unraveled the bandages as soon as Leona climbed onto the bed.
They were practically just hanging off her large breasts anyway, so they weren't hard to remove.
Soon, Leona's bare breasts were fully revealed. In terms of size, they were not lacking at all compared to the other women.
Stroke—
"Ha-ah..."
Leona let out a cute moan as Isaac touched her breasts. Isaac began to knead her breasts with both hands.
They felt soft yet maintained a beautiful shape. As mentioned repeatedly, they were quite large.
"Ah-ang... hnghh..."
"Leona."
"Ngh...? Mmph!"
At the call of her beloved male, Leona looked up only to be surprised. Isaac had started a rough kiss.
Slurp— Schlick— Mmph— Smooch—
At first, it was just a collision of lips, but soon their tongues were intertwined. It was a wild tongue-play that had discarded all gentleness.
Leona felt her body heat up even more as Isaac's tongue toyed with hers.
She moved her tongue to mix with his somehow, while her breasts were kneaded to his heart's content by his large hands.
Meanwhile, his cock throbbed and kept tickling her stomach... she couldn't take it.
Thump!
"Mmph?!"
Isaac was startled once again when Leona suddenly pushed his shoulders. But there was no time to be surprised.
Before he knew it, Leona had climbed on top of him and was looking down with unfocused eyes.
"Haah... haah... hngh."
Slurp— Schlick— Smooch!
Leona lowered her head and roughly explored Isaac's lips. The sweet scent of peppermint made her head spin even more.
Following her instincts, she didn't forget to slowly move her hips.
His cock, as hot and hard as a fire-heated iron rod, rubbed against her stomach. Her large breasts were pressed tightly against him.
Isaac was surprised by her beast-like pouncing for a moment, but he soon responded as she wished.
Until now, he had led the first nights, but today seemed like it would be very different.
Slide— Slip—
Before he knew it, Leona was casting off her trousers and underwear. Even while exploring Isaac's mouth and tongue, she acted as her instincts led her.
Isaac had long since cast off his remaining robe. Thus, the two became completely naked.
"Slurp! Phew! Ha-ang... haah..."
After the long, long kissing session ended, Leona looked down at Isaac with an expression completely steeped in lust.
Isaac had a relaxed face, as if he would accept everything. He stared at Leona for a moment before shifting his gaze downward.
His erect cock was pressed tightly against her abdomen. Unlike Adelia's, Leona's stomach was smooth.
However, it felt firm, as if filled with muscle. It was likely due to the unique muscle mass of a beastkin.
'Normally, I would have licked her pussy, but...'
She was already drenched in vaginal fluid. It was flowing so much that her thighs were damp.
It should be fine to insert it now. Isaac looked at Leona again.
Her face was full of excitement and anticipation, as if waiting for permission. Truly, she was like a beast faithful to its instincts.
"Leona."
"Haah... haah..."
"You can put it in now."
"...... ......"
As soon as he said those words, Leona clamped her mouth shut. Then, her eyes slowly drifted downward.
What came into view was Isaac's long, thick cock. From now on, she would put this massive thing into her vulva.
There was no fear. She just needed to quench this insane thirst.
With that, she slowly lifted her hips. Vaginal fluid poured from her pussy as if a flood had occurred.
Squish—
"Hya-ang!"
Finally, the glans was aimed precisely at the entrance. Just by touching it, Leona let out a shrieking moan.
But Isaac didn't care whether she moaned or not. He grabbed Leona's slender waist with both hands.
She was the one who had acted like a beast first.
"Hngh...?"
Just as Leona, who had felt a slight climax, began to wonder about his actions.
Thud!
He pulled her straight down.
"!!!!"
It was in.
That large, hard cock invaded her vagina without leaving even the base behind.
The sound of the glans and the cervix colliding echoed in her brain.
As a terrifying pleasure, rather than the pain of a first experience, rushed over her, Leona arched her back like a bow.
"Hnghhhhhhhh...!!"
Her eyes flew wide open, and her tongue lolled out of her mouth.
Not just her ears, but even her tail stood straight up toward the ceiling, showing just how shocked she was.
"Hnyaaaaaang!!"
A beast-like moan erupted belatedly. Meanwhile, Isaac enjoyed her tightly gripping vagina.
Since she was a virgin, it was naturally narrow. But the tightness was extraordinary.
Perhaps because there was so much vaginal fluid, it felt stimulating every time he moved. It was a sensation he would never have expected from a virgin.
'Though that's impossible.'
Looking down, he saw a bit of blood leaking out. The blood that symbolized her virginity.
But as if to make that irrelevant, Leona's inside was a masterpiece among masterpieces. Isaac took action while Leona was steeped in pleasure.
Slap! Slap! Slap!
"Hnyang! Nyang! Ha-ang! Ah-ang!"
In a situation where she still hadn't regained her senses, pleasure rushed in repeatedly. Leona let out continuous moans with her back arched.
The sight of her large breasts swaying was a spectacle to behold. Isaac gripped her swaying breasts firmly.
Then, he gently toyed with her sharply protruding pink nipples. As if that wasn't enough, he sat up and bit her breast.
"Hya-ang?! Kya-ang! Ha-hngh!"
Splat! Splat! Splat! Splat!
As Isaac wrapped his arms around her slender body, Leona hugged him back. Having adjusted to the pleasure, she began to move her hips on her own.
For a while, the two embraced and explored each other. Leona moved her hips rapidly as her instincts led her, and Isaac responded faithfully.
He had to lead up until the insertion, but as time passed, just reacting was enough.
Thud—
But it was Isaac who couldn't hold back, as he pushed Leona over. They naturally transitioned from cowgirl to missionary.
As soon as they moved to missionary, Leona wrapped her long legs around his waist. She also hugged him tight with both arms as if she wouldn't let go.
Though it was her first mating, she knew exactly what the male wanted.
Squish! Squelch! Squish!
"Hya-ang! Mmph?! Slurp! Schlick!"
She let out another moan as Isaac thrust his hips, but her mouth was blocked. Isaac's lips had descended upon her.
The peppermint scent that made her head hazy spread throughout her mouth, and his tongue pushed in like a snake.
Meanwhile, her lower abdomen was filled with his cock, and a terrifying pleasure arrived simultaneously. At this rate, she wouldn't last long.
Slide—
Her tail wrapped around Isaac's waist. At the same time, the pressure from her arms and legs grew stronger.
It meant the climax was approaching. Isaac realized this and picked up the speed.
Squelch! Squish! Squish! Squelch!
"Mmph! Ngh! Slurp! Schlick!"
It was hard to moan because her mouth was blocked, but this was enough. Leona began to scratch Isaac's back with her fingernails.
Isaac flinched at the sudden sting, but he ignored it. This much was nothing.
Next, he stopped the kiss and buried his face in her neck. It was time to let her go.
Squish! Squish! Splat!
"Nyang! Ah-ang! Kyang!"
As Isaac increased his speed, Leona let out moans that sounded more like a cat than a human. The more she did, the harder she scratched Isaac's back.
How many times did he thrust into her pussy?
Thump!
Once again, the glans and cervix collided forcefully.
"Hyaaaaaaaaang!"
Leona reached her climax for the first time in her life. Her entire body became as sensitive as an erogenous zone, and her body writhed of its own accord.
Vaginal fluid erupted forcefully from her pussy, which had swallowed his cock. Thanks to that, Isaac's lower body became drenched.
Not only that, but the strength in her arms and legs wrapping around Isaac intensified. However, Isaac didn't stop and continued his thrusts.
Splat! Splat! Splat! Splat!
"Hya-ang! Hnya-ang! Ah-ang! Ha-a-ang! Ha-ang!"
She felt like she was going crazy. The climax wouldn't stop. The lewd sound of water continuously entered her ears.
Because Isaac wouldn't stop even after she reached her climax, she felt like she might faint at any moment.
The sexual desire accumulated due to estrus and the cigar smoke's aphrodisiac effect synergized to turn her mind white.
In particular, this sense of fullness filling her lower abdomen... this fullness was the greatest cause of her pleasure.
"Hngh!"
Shudder! Throb! Throb!
While Leona writhed in her climax, Isaac erupted his semen inside her vagina. Though it was his second ejaculation, a massive amount was discharged as if a faucet had been turned on.
"Ha-aaaaah...!!"
Leona let out a hot breath at the feeling of semen gushing into her vagina. Her brilliantly shining eyes grew dull, and her mind became hazy.
So this is sex. This is mating between animals. What an incredible pleasure.
She wanted to do more. She wanted to do it so roughly that her mind would completely break.
It was around the time Leona was thinking such things.
Slide—
Isaac brought his large cock in front of her face. Without being completely drained, white semen was dripping from the tip of the urethra.
As soon as Leona saw it, she reflexively flicked her tongue. As if the remaining semen was too precious to waste, she licked the tip of the urethra.
"Lick. Lick. Slurp. Schlick."
Soon, the glans entered her mouth, and Leona sucked on it greedily. As if she intended to drink every last drop of semen left in the urethra.
Isaac exhaled and gently stroked her head. As expected of a beast, she was acting exactly as her instincts desired.
The other women had also shown themselves to be faithful to their instincts, but Leona was even more intense. She was coveting his cock simply as a means to resolve her estrus.
In that case, he would have to give her more. Isaac pulled his member out of her mouth.
When he did, Leona leaned her face forward and followed the cock. The way she flicked her tongue made it seem like she was treating it like a truly delicious ice cream.
"Do you want more?"
"Heaa... haaa..."
Leona didn't answer. Isaac's words weren't even reaching her ears.
However, her eyes were fixed intently on his dick. It looked as if her reason had almost entirely evaporated.
Isaac couldn't help but smirk at the sight. At this rate, conversation was impossible.
More accurately, a 'conversation of the flesh' was more appropriate. While other women used dialogue to build the atmosphere, Leona was different.
Only sex mattered. Sex where they craved each other like animals was enough.
"Since it seems you haven't had enough yet."
Isaac moved Leona's body himself. First, he turned her around to face away from him, then guided her into a position with her hips thrust high in the air.
Leona, realizing what he wanted, followed his lead. As she took the pose with her backside raised, her instincts spoke once more.
Wiggle, wiggle.
"Nyaa..."
She swayed her luscious hips from side to side, even her tail flickering playfully. It was the lewd courtship of a female tempting a male.
The sight of her shaking her ass, oblivious to the semen dripping from her pussy... she was the very definition of a wanton woman.
Furthermore, the way her tail swished back and forth was more than enough to set Isaac's heart ablaze.
Thrust!
"Kyann!"
Isaac buried himself inside her pussy without any warning. Leona let out a cry drenched in joy and pleasure.
Grip!
Not only that, but Isaac firmly grabbed the tail that had been flickering just moments ago. How long had he held back from seizing it?
But from now on, this tail was nothing more than a 'rope.' A rope to help him drive into her even harder.
Slap! Crack! Thud!
"Nyaa! Hnyah! Kyah!"
Leona no longer made human moans. She was merely a cat howling in the throes of pleasure.
Every time he drove his dick deep inside, her luscious hips rolled like waves. The curved pelvis beneath her slender waist was a feast for the eyes.
Moreover, the semen and vaginal fluid inside her were mixing together, creating an effect like love gel. On top of that, she possessed a tightness that was unimaginable for a virgin.
It wasn't just a simple squeeze; she was adjusting the pressure as his dick stirred her insides. This, too, must be due to the unique instincts of a beastkin.
It was erotic. Truly a lewd and obscene body. Was every beastkin in estrus like this?
Slap! Splat! Splat! Thud! Thud!
"Hnya! Haah! Ahh! Kyah!"
Her pussy tightened even more fiercely. This was surely the signal of an impending climax.
Isaac maintained his pace before driving all the way in, right to the base. This was one of the techniques he had acquired through his relationships with various women.
When one is gradually approaching the limit and a sudden, stronger stimulus is applied, they can easily reach a peak.
Throb!
"Nyaaaaaa!!"
Leona's eyes flew wide as his large glans collided forcefully with her cervix.
Not only the tail held in Isaac's hand, but even her ears stood bolt upright.
Splash!
As if her 'lower mouth' was also climaxing, vaginal fluid sprayed in all directions. It was so intense that a few droplets even splashed onto Isaac's face.
An orgasm had found her once again. Leona's arms, which had been supporting her upper body, trembled violently before she finally collapsed.
Her posture naturally left only her hips raised high. Isaac gave a mischievous grin and leaned his upper body forward.
Then, he whispered sweetly into the ear perched atop Leona's head.
"We're not done yet, you little she-cat."
"Ahng..."
The moment he said those words, Leona wiggled her hips despite her dazed state. His rock-hard, erect dick was still buried deep inside her.
Isaac listened to the squelch, squelch sound of his movement. It seemed she really hadn't had enough.
The same went for him. He took Leona's ear into his mouth and gave it a sharp nip.
"Hiee?!"
Leona flinched in surprise, her body shuddering. Isaac, still biting her ear, felt her tremors.
Press—
Isaac pressed down, pinning Leona beneath him. Then, he began to grind his hips in that position.
Squelch! Splat! Squelch! Squish!
"Hgh! Kyah! Nngh!"
Leona bit down hard on the blanket as pleasure began to storm over her once more. Tears streamed mercilessly from her eyes, yet the corners of her mouth were turned up.
Though she had only just reached a climax, the renewed movement began to make her expression melt away into bliss.
Lewd sounds echoed through the room as Isaac pressed down on Leona's head and ravaged her pussy to his heart's content.
If she wanted to be treated like a beast, he would act like one. Perhaps that thought reached Leona, as she offered no resistance whatsoever.
He continued to thrust without pause, even as vaginal fluid splattered everywhere.
Throb!
"Hnnnnngh!!"
Once again, a climax began to tear through her brain. Semen poured out in surges, filling her womb, and her entire body became hypersensitive.
Leona struggled, her limbs twitching in the face of unbearable pleasure. But it was futile, as Isaac was pinning her down from above.
It was a situation where she was being dominated by an overwhelming male. Leona felt a profound sense of satisfaction from Isaac, who was superior in every way.
He was more than worthy of claiming her. She wanted to receive his seed and bear his child.
Her beastkin instincts screamed as much, and Leona didn't bother to deny them. For now, she simply wanted to surrender her body to this pleasure.
Squelch— Pop!
As Isaac pulled his dick out of her pussy, a sound like a cork popping echoed. Immediately after, white semen began to trickle down from her private parts.
"Whew."
Isaac, who had been driving into her relentlessly, took a moment to catch his breath. He had expended quite a bit of stamina by being on the offensive since the moment of insertion.
Of course, he would recover quickly after a short rest. Above all, he had the medicine Musk had gifted him.
It wasn't a drug like Viagra, but literally a tonic that was good for a man's overall vitality, and he had been taking it for a while. He wondered if its effects would truly manifest tonight.
Slide— slide—
"Hmm?"
"Nyam..."
In the meantime, Leona had crawled over and taken Isaac's dick into her mouth. He had the illusion that heart shapes were etched into her unfocused eyes.
Regardless, Leona licked his dick as if grooming it before pressing her cheek against it.
Then, she began to wiggle her hips again. Her tail was swaying too.
"Grrr. Nyaa."
"...You want more?"
"Haah."
By the looks of it, this lewd she-cat wanted more. Isaac let out a short laugh and stroked her head.
At his display of affection, Leona pressed her face even closer to his dick. Truly, she was more like a house cat than a lion.
Well, he had to give her what she wanted. Isaac stopped stroking her head and flopped onto his back.
It was a position that emphasized his dick, standing tall like a mountain. Looking at it, Leona felt her nether regions grow even wetter.
Though she was already soaked to the bone, the scent of the male caused even more vaginal fluid to flow. It was a phenomenon unique to a beastkin's estrus.
"Do whatever you want."
"Hng?"
"You can lick it, suck it, or put it inside and stir it around as much as you like."
A beastkin's estrus doesn't last that long, but...
"What's it going to be?"
"Haup!"
Slurp! Schlop! Suck!
The night was long.
