The lewd, untouched hole, tighter than her pussy, not designed for milking a cock…
As he touched it with his thumb, stroking it gently as if to confirm its shape, Rias's body twitched. She raised her rear high, swaying it lewdly, begging Mitarai to toy with her more.
"I'm about to take your anal virginity, Rias. I'm gonna stick my dick in this hole you've been developing, and from today, I'll change it from a hole that just excretes to a hole that milks me dry."
"Aaahhhh You're taking my virginity, Takashi ... Make my anus into a lewd hole to your liking... mm."
He grasped his penis and pressed the glans firmly against her tightly puckered opening. Slowly, the glans was swallowed inside.
This excretory opening had a stronger resistance than her pussy, squeezing so tightly it felt like it might bite his penis off.
"Ohhhh, it's going in~!! The cock is in my assholeee."
Rias let out a lewd, guttural moan, her body trembling. Mitarai also let out strained groans as he pushed his hips steadily forward.
Even though they had prepared it, the hole, surprised by its first penis, reflexively squeezed down, feeling incredibly tight. It was tighter than Koneko's pussy, she was small with a lolita-esque appearance, but the anal canal had more depth, and he managed to successfully bury his entire length.
Squeezed from base to tip, Mitarai felt like ejaculating immediately. In fact, it might be better to cum once to lubricate things.
"Ngh... Rias, I'm going to cum...!"
"Y-yes. Do as you wish."
Splurtt Spurt Splattershhh…
Unlike her vagina, the hot semen was poured directly into her intestines, which lacked a womb. The masculine desire dyed the pink mucous membrane a stark white.
A searing heat slowly permeated the intestinal walls, and from Rias's crotch, her own hot fluids spurted out forcefully.
Even though it was her first time having anal sex, she was having an internal orgasm. Her face was slack with ecstasy, receiving the pleasure with moans like a zombie's, "Aaahhh ."
"Nngh!... Haah, whew... This should make the anal passage slicker. Hey, Rias? ...Ah, she passed out, huh. Well, I'll just make use of her like this."
When he pushed his cock back into her asshole, Rias regained her awareness.
Grabbing her plump buttocks, he slammed his hips back and forth, thwack thwack.
The pronounced glans corona, his re-hardened shaft, scraped and stirred the anal flesh, softened by his recent ejaculation. He easily thrust deep, pounding into her with the full weight of his body.
Rias seemed to push her ass up against him, staying flush with Mitarai's hips, shaking her body lewdly as if rubbing her butt against him. Her vagina was also melting in orgasm, trailing threads of love juice and staining the futon.
Her endearing, instinctive fawning over the superior male was too much for Mitarai, who intensified his thrusts.
Mixed with the sound of slapping flesh, each time his dick withdrew from her anal hole, a lewd sound of displaced air could be heard: fwoomp fwoomp. It sounded almost like farting, and coming from a breathtaking beauty like Rias, it only aroused him further.
"Your pussy feels amazing, but your ass is a treasure too, this is insane!... I just came a bit ago, but I already want to cum again...!"
Pressing down as if to crush her big ass with his weight, he drove the tip of his penis deep inside. He twisted his hips, grinding and stirring her deepest reaches.
"--Nngh! O-oh! Nnn--Aaahn..."
Rias's sweet, completely melted voice involuntarily stirred his masculine urges.
The semen in his sac churned and heated up. He wanted to fire it immediately, to pump it deep into her.
Suppressing that urge, he sank his hips down. He relentlessly parted the narrow rectum, scraping and forcing his way to the deepest part.
But he couldn't hold back for long; his restraint crumbled. The word 'reason' vanished from Mitarai's mind, replaced solely by the thought of releasing his semen into this incredibly pleasurable asshole.
His body moved on its own, slamming his hips with such force that sweat flew. With each withdrawal and insertion, squelch squelch, the intestinal juices mixed, drawing out lewd, wet sounds as he continued his pistoning.
Each time he scraped the intestinal walls, her grip tightened, and even in her blank mind state, her anal opening was steadily learning the peak of pleasure.
Lubricated by the thick, sticky cum he had already deposited, the intestinal walls, while providing adequate resistance, diligently learned a role beyond mere excretion, firmly gripping his cock.
He wrapped his arms around Rias's body, holding her close as he sprinted through the final stretch.
Relishing the folds that naturally clung to him, he thrust deep, pushing past the depths of her intestine and finally, even beyond, to the back of her womb. When he crushed the forlornly trembling womb with his penetration, her body jerked delightfully.
He stimulated every last bit of intestinal flesh, scraping and stirring, the flared glans corona scraping and reaming her anal hole as it withdrew, only to plunge back in.
Over and over, he relentlessly hammered the back of her womb.
She let out sweet cries, her body jerking and struggling as if to escape his embrace, but he held her tight, as if teaching her the strength of a male.
Mitarai pumped his hips back and forth with animalistic ferocity, thud thud, slamming against the back of her womb, his entire penis trembling in preparation for ejaculation.
"Nngh...!"
Splirt Splurt Spurtt Bubblesh Splattersh Slurt…
The milky, odorous masculine desire was released from his gaping urethra. It flowed deeper and deeper, trying to dye the congested, bright red intestinal lining white.
"Ah, nn! -- Nngh! Ah, hii! Nnn! Cu-cumming! I'm cumming"
Finally, perhaps the sensation of semen bathing her intestinal walls brought her back to her mind, and she panted lewdly, like a trained dog, to convey her peak to Mitarai.
Basking in the most intense climax of the day, she clenched her anal opening tightly around him.
The grip was so tight it was almost painful for the dick inside, but seizing the opportunity, Mitarai moved his shaft, grinding and twisting against the constricting walls.
He moved, as if imprinting his shape onto her, smearing the still-flowing semen within her. The hole, once meant only for excretion, was steadily transforming to his liking.
His serious ejaculation, befitting someone as the red dragon emperor, lasted over a minute, and her belly became slightly swollen, perhaps from the sheer volume of cum deposited.
"Fuaa... ah... unn..."
Rias let out a completely melted, contented sound. Drifting in a daze between consciousness, she was likely immersed in the intense waves of sensual pleasure, her small tongue hanging out slackly, unaware of her current state.
"Man, I came a lot. It's crazy that even after cumming three times, it's still not satisfied. Is this what they call youth? Hmm... I got carried away just now~!!"
"… Maybe I'll go take another bath. I'm all sweaty and sticky anyway."
Left alone in the room, semen, expelled from Rias's anal opening, flowed back out, spurting forth with an obscene sound.
With each breath Rias took, more would spurt out, staining the futon beneath her.
However, Rias was out of her mind and could only lie there in her lewd state.
Surely, by the time Mitarai returned from his bath, she would regain awareness, only to be embraced by him again until she passed out.
