“Olivia? Are you in there? Open the door for a moment.”

But what pulled Olivia back to reality from her hazy state was Lime’s all-too-familiar voice. She saw him pacing back and forth outside the small glass window in the door—he had been the one who knocked earlier. Fortunately, the window was covered with a translucent lace curtain so only silhouettes were visible, but still, the fact that she was doing such things with Alois with only a door between them and Lime stimulated Olivia’s sense of depravity. Lime had been her younger brother since childhood. She dreaded to think how he would react if he discovered her in such a lewd state. He might feel embarrassed and try to understand, but what if he condemned her as immoral……

“Does it excite you more to be doing this in front of your brother?”

Alois’s eyes narrowed sharply as Olivia’s inner walls twitched with excitement at the mere thought. The beast in heat, whose pride was hurt by his female paying attention to another male, often grew angry over small things like a child. Displeased, Alois growled and bit her earlobe painfully.

“Well then, why don’t you have a nice chat with that brother of yours.”

Alois deliberately pushed Olivia toward the door so her silhouette would be visible through the small window, and thrust his hips upward. The door shook with a small bang. Olivia’s eyelids trembled as she was caught between the door and Alois. A sharp thrill ran through her n*pples, roughly pressed against the hard door.

“Olivia?”

“Huah! Nngh, nng…… Wh-what? Ngh.”

“The conductor has a message about our arrival time, come out for a moment.”

“No, I, I, nngh, ah! S-sorry. Ri-right now, a bit, ahang!”

Alois deliberately thrust his hips upward whenever Olivia opened her mouth to speak. He kneaded her soft b*ttocks with both hands to his heart’s content, grabbing her pelvis and pulling it toward his body while thrusting his c*ck to the root into deeper places. The door rattled with his rough movements.

“…… Are you sick?”

Olivia shook her head, praying that the noise of the train would drown out her moans. Though she knew the other person could only see her silhouette, there was nothing else she could do. She leaned her cheek against the glass window with the lace curtain and breathed heavily.

“Go ahead, keep, hoo, trying to hide it, hn, if you can.”

“Ah, angh! Ah! La-haah later, I’ll, co-come, haang, ngh!”

She could no longer distinguish whether what she uttered were words or moans. Her cries of pleasure mixed with words grew higher like screams. Olivia now barely registered the presence outside the door, surrendering to lust as she raised her tiptoes and swayed her hips up and down. Only then did a proud satisfaction appear on Alois’s face. Though there was some commotion outside the door, she couldn’t hear that either. All that mattered was the burning hot c*ck setting fire to her inner walls, scratching every wet spot, and thrusting into the ticklish depths.

“Ah, angh! It’s, good, haa, ngh! Inside, hng, ang, aah!”

“Kuk, yes, now, hoo…… soon, haa, ugh.”

Nibbling on Olivia’s cheeks, who begged him to ej*culate inside quickly, Alois slipped his hand between her br*asts pressed against the door. He rubbed the firmly swollen nub with his palm while firmly grasping her soft flesh. Her tiptoes bobbed up and down precariously as his hip movements accelerated. The hand that had been kneading her br*asts slid down to press her lower abdomen, pulling her body tightly against him. His blunt c*ck forced its way through the narrow passage and pushed into her womb.

“Too deep, nnngh! Ahang!”

Olivia threw her head back, rolled her eyes, and trembled violently. Saliva that she couldn’t fully swallow dripped from her parted lips. The focus in her wide-open eyes shook terribly. Her vision flickered hazily before turning completely black. It felt as if her womb and inner walls would be completely drenched in Alois’s s*men.

Her tightened inner walls gripped Alois’s c*ck and wouldn’t let go. The junction especially throbbed, pressing so hard it almost cut off blood flow to his c*ck. Alois, who clenched his teeth while ej*culating, sat down heavily on the bed while still spurting cum from his c*ck inside her. Naturally, Olivia plopped down on his thighs, still holding his c*ck.

“Ahng!”

Her hands naturally fell forward and grabbed her thighs, spreading them wide. While massaging her groin and pressing on the junction, his hands naturally played with Olivia’s p*ssy, which looked messy with cum and saliva. Her cl*toris, stimulated continuously and now hardened, stiffened and trembled at the slightest touch.

“What happens if we keep stimulating ourselves in this state?”

Alois parted the valley with his fingers and strongly pressed and rubbed where her cl*toris was located. Olivia, who had been languidly leaning back in the momentary exhaustion after climax, gasped and gripped his arm tightly.

“N-no, don’t, ah, hnng, h, ah……”

Even without him moving, the train’s rocking made his c*ck poke at her highly sensitive inner walls, and her cl*t, which easily crumbled from even a small stimulation after multiple climaxes, was continuously and roughly touched. She felt an urge to urinate. Though she tried to endure by gritting her teeth, her p*ssy kept twitching anxiously at the continuously building stimulation. Olivia twisted her body, crying out her refusal several times, but couldn’t escape from Alois, who had wrapped around her like a snake.

“Hngh, nngh, ah, no, angh, nngh, haang!”

Finally, when the p*nis buried inside pushed against the end of her womb and entered deeper, at the moment his fingernail carelessly scratched her cl*t, Olivia shuddered with a sharp cry. Clear liquid burst from between her legs like a fountain. Alois’s fingers entered Olivia’s gaping mouth and pressed down on her small tongue as she gasped for breath like she’s about to pass out. Even as she lost consciousness from the unbearable shame and depravity, Olivia habitually sucked on Alois’s fingers filling her mouth.

A low laugh sounded in her ear. That’s too much. But such complaints were utterly useless to the beast in heat.

* * *

The prolonged heat cycle finally came to an end. Olivia had spent so much time accommodating Alois’s c*ck that she now felt empty without it. She had even grown accustomed to the sensation of his excess cum flowing from her gaping hole. Lying completely n*ked without a blanket in broad daylight no longer embarrassed her. Rather, whenever Alois’s gaze swept over her skin, her legs spread wider and her hips moved on their own.

“Nngh, ngh, hnnnn……”

Her moans, mixed with fatigue and passion, were faint. But unable to ignore the pleasure honestly spreading through her body, Olivia occasionally rotated her hips despite her limp body. Ah. Her ticklish inner walls felt chillingly good as his fully packed c*ck roughly scraped against them. She carefully traced her swollen belly, bulging from the s*men pumped into her and the c*ck still rampaging inside.

“Alois, now hngh, a bit, come to, ahnng, ahang!”

The c*ck thrusting inside swelled once more and then erupted like a violent stream. Olivia, whose first experience had been during a heat cycle, had thought all ejaculations were like this. But only after mixing bodies with Alois outside his heat cycle did she notice how unique he was during his heat.

“Ah, aah, ahngh!”

s*men surged forth, forcibly stretching her narrow womb until she felt her stomach would burst. Her lower abdomen protruded visibly, and Olivia twisted her body, clawing at the pillowcase. Her widely spread legs convulsed pathetically. The afterglow of pleasure that had beaten her entire body was too intense.

A languid smile dripped from between her gaping lips. Her chest moved violently up and down with her rough, panting breaths. Even while enjoying the languor of ej*culation, Alois playfully kept scratching and toying with Olivia’s er*ect n*pples with his fingernails. After savoring the feeling of her soft, squelching, liquid-filled insides by poking it several times, Alois slowly withdrew his c*ck.

“Haanng……”

Alois pressed down on the insides of Olivia’s thighs with both hands to prevent her from closing her legs. The red, swollen inner flesh of her walls occasionally flashed through the hole, which had been holding his c*ck for who knows how long. When he pushed apart the flesh of her mound with his fingers, s*men flowed out through the still-pulsating hole.

“This makes it look like you’re pregnant.”

Alois murmured as he traced her swollen lower abdomen, then inserted his fingers into the lower hole to spread the folds sideways while gently pressing on her belly from above.

“No, nooo. Nnngh! Hngh, ahang!”

All the liquid sloshing inside flowed out at once through the lower hole due to the pressing pressure. Whitish fluid flowed onto the sheets, wetting his fingers that probed inside. Olivia wildly shook her hips, feeling another climax along with shame at that strange, emptying sensation. She closed her eyes tightly as she rotated her hips against the inserted fingers as if guiding the flow.

* * *

The hand motions wiping the moisture from her hair were affectionate. The lips occasionally landing on her shoulders were gentle enough to be respectful. Sitting on Alois’s thighs, she leaned her back against his chest. Olivia, who had been melting like a marshmallow on his body, suddenly came to her senses when she felt the presence of Alois’s massive c*ck rubbing between her butt cheeks.

“Isn’t your heat cycle over?”

Just to be sure, she seriously looked into Alois’s eyes. His focus was properly fixed, and there was kindness remaining in his gaze mixed with a strange smile—it was indeed the Alois she knew. Then this hard, er*ect thing……
