Misaki slipped out of her dress and lay back on the bed.
"Hey, Kotaro. I'm on the pill, so... you can keep going raw."
"...Huh. Are you sure...?"
She had been about to pull out a condom she'd hidden under her pillow when she surprised him with this.
"Mm. Do whatever you want with me, Kotaro. I want you to fill me up with your cum... Ahh, why do you have to get so big...?"
Her uninhibited words made his cock spring taut.
"...Thank you. Let's do it."
"Heh, yeah. But it's scary how real the voices sound outside..."
Misaki, with an accepting smile, glanced around nervously. The walls were thin, and the occasional chatter of students in the corridor or outside drifted through. The bed was placed opposite the wall shared with the neighboring room, but even then, the difference was negligible.
"Hmm... Should we just curl up in the futon?"
"K-Kotaro's futon..."
"Huh? What's wrong?"
"N-no, it's nothing. It's nothing at all." Misaki shook her head vigorously.
Puzzled but undeterred, I leaned over her and draped the futon over us with a soft whoosh. The little senior wriggled beneath me, letting out a suggestive mmn..., and I couldn't help but find it unbearable.
"It's a little warm, but this should help keep us hidden... Wait, Misaki-senpai?"
"Snn, snn... Ah!"
Misaki, who had been sniffing the air, let out a dazed gasp.
"...I-I didn't see that! Eep!"
I playfully brushed my fingers against her soft breast, eliciting a cute moan that echoed through the room. Misaki hastily covered her mouth, shooting me a resentful glare. I'm sorry, but she's just too adorable.
Come to think of it, Misaki-senpai did say she liked my scent...
A chill ran down my spine as I remembered what she'd said in her room the other day.
"...Shall we try a different approach?"
"Huh? What? Oh, you... you're okay with that...?" Misaki asked anxiously as I removed the quilt. Kotaro smiled gently and casually held up his pillow in front of her.
"If you feel like covering your mouth, feel free to use this."
"Huh...?"
Kotaro's declaration—"Take as long as you want to smell it"—made Misaki blush. Even her flustered expression is cute, he thought as he gripped his erection and pressed it against her vaginal opening. She had been wet all this time, always ready to receive her lover's manhood.
"I'm going in."
"Wait, just a minute... Ngh..."
As he thrust his cock into her with wet, squelching sounds, Misaki squeezed her thin lips together, her pillow pillowed beside her face.
"Your pussy, Misaki-senpai... it's burning hot..."
"S-stupid... You didn't have to say that... Ngh..."
Squelch, squelch... The obscene sensation of his shaft sinking deeper into her pussy. Misaki's small mouth gaped open as she desperately gasped for air.
"Stop... Kotaro's penis feels too good... Ahh... No... I can't... I'm going to make a sound... I can't help it...!"
Her troubled words, whispered as she writhed her hips, sent shivers down my spine.
"Use the pillow. Go ahead, sniff it as much as you like."
"U-um... Nnnn..."
Misaki cautiously draped the pillow over her face, pressing her nose against the spot where Kotaro usually rests his head, and began taking deep breaths.
"Ugh...!?"
Her body jerked violently, and her vaginal muscles suddenly clenched around my shaft in a lewd, sticky grip.
"Ngh... Kotaro's scent... Nn... Ngh...!"
"..."
Misaki clutched the pillow tightly, her eyes glazed over. With each snort, her muscles tightened around my shaft, and her full hips trembled as they rose and fell.
"...This way, I can really let loose."
"Mmm...? Mmm, mmmn... Nnnngh...!"
Gripping Misaki's slender waist firmly, I thrust deeply into her. Her delicate body arched sharply, her full breasts bouncing with the force. Drunk on the intense clench of her vaginal walls, I forgot gravity, my hips rising as I pistoned my cock in and out of her motionless body.
"Mmm, mmmgh, mmmfuuu...!!"
Misaki's body convulsed as if broken, a torrent of love juice spilling from our joined flesh.
Misaki-senpai... She's so aroused by my scent...
Her breathing, meant to calm her, only intensified her arousal. Thinking about it now, it made sense that Misaki, already so sensitive, would become so utterly undone.
"Ngh... No, no, I'm gonna... I'm gonna... I'm gonna... Ngh...!"
Misaki gasped hoarsely, her legs shooting out in a perfect V as she climaxed. Her body, suddenly remembering gravity, collapsed limply onto the bed, but Kotaro didn't stop thrusting.
"Senpai, you've gotten so much more sensitive. I'm thrilled," he murmured, stroking her soft belly.
"Mmm...! No, no, what are you doing? Even when you... it feels so good...!" she whimpered, her voice barely audible, writhing to escape his touch.
Kotaro, determined to tease this masochistic senior to her limits, continued stroking her abdomen deliberately.
"I'll touch an even more sensitive spot now."
As he reached for her nipples and clitoris, Misaki's eyes widened, and she shuddered violently.
"No, no, no... Ngh...!"
Pinching her nipples between the thumb and index finger of her right hand, and stroking her clitoris with the thumb of her left, Misaki's voice rose even higher. Her inner thighs spasmed unnaturally, and her sweat-damp skin rippled with tension.
"Fuuh... fu... fuuuu... fu... nfuuu...!"
Misaki's body trembled violently, her muffled gasps escaping in ragged breaths. Her pale pink nipples were swollen and erect. The sight of her lover's urgent, unreserved state sent my heart racing relentlessly.
"Misaki-senpai... can I go from behind? I want to fuck you senseless."
"...Mn, yes. Do more...?"
Gently grasping the base of my cock, her softly smiling face tightened my chest in a painful squeeze.
Misaki wriggled into a prone position, her large, round buttocks jutting out defiantly even as her face remained buried in the pillow. The coexistence of cuteness and naughtiness in her gesture intensified my arousal.
They're so big and smooth...
As Kotaro gently stroked her plump, firm buttocks, she playfully scolded him, "Hey, hey, what are you doing...?" Her hips wiggled as she tried to escape his touch.
"It's just because they're so big that I can't help but notice them... Even you must think they're weird, right, Kotaro?"
"...Actually, I've thought they were amazing since the first time I saw them."
Her hips froze.
"Huh? R-really? You're not just saying that?"
"I'm serious. I could stroke them for hours."
"That's creepy!"
"Hey!"
A little shocked, Misaki chuckled mischievously and swayed her hips as if to tease him. When he smoothly slid his finger from her anus down to her labia, she playfully squirmed away with a cute, "Eep!"
"I was worried about it before, but... if you like Kotaro, I guess it's fine... Hey, am I staring too much...?"
As I gripped her buttocks and stared intently at her anus, she kicked me softly with her little feet.
"Come on, just fuck me already. You want to come inside me, don't you?"
"...Yes...!"
Misaki turned her head slightly, grinding her dripping wet pussy against my cock. I gulped, gripped her firm buttocks tightly, and thrust my erect shaft deep inside her.
"Ugh... Ah... Uuuu...!"
Misaki buried her face in the pillow, trembling violently. Her raised hips sagged down, collapsing onto the bed. Still on his knees, Kotaro dug his fingers into her buttocks, maintaining the thrusting motion.
"Ah, heah, ah... This... it's making me so weak... it feels so good... doesn't it... ah, ah, ah, ah..."
Misaki whispered, her voice trembling, in sync with the creaking of the bed.
"Your anus, Misaki-senpai, it's twitching."
"What?! Y-you don't need to say things like that... eep!"
I gently pressed the tip of my right thumb against her sepi-toned anus, nestled at the center of her radiating wrinkles. Misaki let out a cute little shriek and hastily buried her face in the pillow.
"Wait, Misaki-senpai... could it be that you feel this too?"
"Huh? Ah! Hey! Stop! No, don't do that! I don't know anything about that! Ah! Hey, that's dirty! So dirty...!"
I gently stroked the area around her anus, then softly pushed the tip of my thumb inside. As the delicate pink opening accepted the intrusion, Misaki's body spasmed like she'd been electrocuted.
"Senior Misaki, I absolutely won't touch you if you don't want me to. But if you're even a little bit interested... may I continue?"
"Ugh... Kotaro, that's such a sneaky way to ask..."
Though he spoke earnestly, he continued to gently thrust his thumb into her anus, each time sinking it a little deeper. Did Misaki even notice?
She groaned for a while, "Ugh... ugh..." before finally burying her face in the pillow with a resigned, "Fine, do whatever you want."
"...Thank you. Just let me know if it hurts."
"Okay... mmh, mmh, mmhuuu..."
As her anus gradually relaxed from the repeated thrusts, he pushed his thumb deeper and deeper. Misaki arched her back like a cat, arching, rounding, arching again.
Whoa...!
Misaki's body stiffened abruptly, her muscles clenching down fiercely on his shaft with an intensity that nearly made him lose consciousness.
"M-Misaki-senpai, please relax a little more...! If you keep this up, I'm going to come..."
"T-That's impossible...! Just pull your fingers out, Kotaro...!"
Just as his fingers were about to reach the root, her vaginal walls contracted even more forcefully.
"Ah, damn it... Kotaro, stop getting bigger...!"
"I can't help it! You're squeezing too tight, Misaki-senpai...!"
As they bickered, their mucous membranes rubbing together, the suppressed urge to ejaculate suddenly exploded.
"Ugh...?!"
"Ngh...?! Nngh, nkuu, nfuuuu...!"
Semen erupted from the glans like a surprise attack, flooding Misaki's insides. Her plump buttocks squeezed together tightly, the muscles of her vagina clenching even more fiercely. Gurgle, gurgle-gurgle-gurgle... An unabashed torrent of semen poured into Misaki's body.
"Haaaah... Ah, no way! Ugh, stop, c-come on..."
As I tilted my head back, reveling in the intense orgasm, Misaki's voice suddenly brought me back to reality. My thumb, which had been partially inserted into her anus earlier, was now buried all the way to the root.
"I-I'm sorry! Does it hurt?!"
"N-no, it doesn't hurt. Even I'm surprised by this..."
Misaki, with both my cock and her thumb fully in her mouth, lifted her head from the pillow and muttered awkwardly.
"Ugh... Kotaro's even developed my ass now..."
"I don't think you can call this 'development,' can you?"
"..."
Her vaginal walls and anus clenched rhythmically, almost as if in anticipation.
"Senior Misaki, you're such a masochist."
"N-no, I'm not... Ngh!"
As I slowly withdrew my cock, Misaki's hips jerked upward, her plump buttocks lifting. A lewd mixture of semen and love juice spilled from the glistening crevice between her cheeks with a wet squelch.
"Come to think of it..."
Misaki unsteadily sat up, crossing her legs in the traditional Japanese style as she faced Kotaro.
"Kotaro's penis gets a little bigger right before it's about to come, doesn't it?"
"Oh, really?"
Her eyes, still glazed with post-orgasmic pleasure, stared intently at his half-erect cock.
"...Actually, it's a little too big and it hurts."
"Huh?"
"...But that 'little pain' has kind of become addictive..."
"Huh?"
Trying to hide her embarrassment, she stroked her sweat- and semen-covered cock, bending down. Gently brushing back her sweat-damp brown hair, she took his half-erect shaft into her mouth with a wet pop.
"Mmm... schup, schup, schup... pfft. What a strange taste... My scent is mixed in with it, too. Mmm, Mmm..."
"U...ah...?"
After such a masochistic remark, a smooth transition into a cleaning fellatio was inevitable. There was no way he could remain unresponsive. His cock swelled and throbbed inside her warm mouth.
"Damn it... It gets hard so quickly..."
After neatly swallowing the semen and saliva, she playfully scolded me, then rubbed her cheek against my saliva-covered cock.
"M-Misaki-senpai... aren't you getting more and more ecchi...?"
"Mmm... Does Kotaro not like having an ecchi girlfriend?"
"I love it!"
"...You're too honest, idiot."
"Oof!"
For my honest answer, Misaki's cheeks flushed crimson with an emotion other than arousal as she gently nipped at my glans.
"Ugh, ugh!"
"Hey, Misaki! Senpai...?"
As if enjoying herself, she gave me a mischievous, upward glance and continued her gentle bites from the glans down to the shaft. Her cuteness was so overwhelming that my facial muscles twitched unnaturally.
"...I started this myself, but now I'm getting embarrassed."
She seemed to come back to her senses.
"Misaki-senpai... you're too cute."
"...Shut up."
Her gesture of turning her face away with a hmph was just too cute, and I couldn't help but give her a tight hug.
