'Fooling around with Akeno. Making a baby with Akeno.'
Just thinking about it heightened Kazuki's motivation, and along with it, his cock grew even harder. Despite the situation, his cock swelled and thickened, and the breast flesh moving vertically continued to rub against it.
"How about this?"
"Uwaah..."
Saliva drooled from Akeno's mouth onto his glans. The viscous, warm fluid spread over the entire glans and dripped down the shaft. It slid into the space between the touching breasts and cock, moistening them both.
This brought a change to the previous friction.
Squish, squish, squish!
With each motion of the titty-fuck, wet sounds now played. Using saliva as a lubricant made the handling smoother. The speed of the cock-handling visibly increased, and the warm saliva grew even warmer as it enveloped his cock.
Enveloped by both saliva and breasts, his cock was overjoyed.
Then, a further change assaulted Kazuki.
"Slurp, slurp, gulp, slurp."
"Nnn~~!?"
After kissing his glans again, Akeno swallowed it whole. While moving her breasts, she welcomed his cock firmly into her mouth, coating it in saliva.
Her tongue lapped at the coronal ridge and frenulum as she sucked from zero distance. This was undeniably a titty-fuck blowjob.
His cock completely vanished, lavished with Akeno's affection. There was no escape. Or rather, he didn't want to escape.
With an expression mixed with agitation and delight, Kazuki let out wordless sounds and could only watch Akeno's actions.
"Shhhh!!"
Enduring was impossible.
"Slurp slurp slurp!!"
He could only shudder all over.
"Jyu-zozozozooooohhh!"
Finally succumbing to Akeno's wholehearted titty-fuck blowjob, Kazuki ejaculated.
Splurt~! Splurrt~!
The semen shot out. Immediately after emerging, it spread inside Akeno's mouth and was swallowed down by her gulping throat. Gulp, gulp.
Watching the alluring Akeno, her cheeks hollowed, drink his cum was an experience beyond description.
The person who first thought of a titty-fuck blowjob was a genius...!
In a strange twist, Kazuki felt admiration for this predecessor and smiled happily.
"Gulp slurpp!"
All the while, Akeno's semen-drinking continued, the stimulation causing sperm to be sucked up one after another.
Since Akeno was also Rias's peerage member, she was a devil. But seeing her like this, she seemed more like a succubus than a devil.
Rias, said to be a pure-blooded devil, was similar. Were all devils this utterly lecherous?
"Nn, pu, haa... nn, slurp, gullp. That's the first one."
Releasing the glans from her mouth, Akeno wiped off the adhering semen with her tongue. As declared, she apparently had no intention of stopping at just one.
Her tongue, moving as if searching for the next load of sperm, rubbed his frenulum with slurp, slurping sounds, forcibly heightening Kazuki's excitement.
"I'll continue to dote on you, okay?"
What would become of him by the time the test drew to a close? Imagining himself dried up like a withered tree, Kazuki felt a twinge of fear, yet from the bottom of his heart, he also eagerly anticipated being doted on until that very state came to pass.
"Slurp, squish, slurp, slurp, slurp!"
The sounds of blowjobs reverberated through the classroom.
Splat, squish, squelch, squish!
The sounds of a saliva-drenched titty-fuck.
Akeno, on her knees on the classroom floor, lovingly devoted to his cock while gazing intently at Kazuki's face.
The overall composition didn't change much, but Akeno, who continued to grow and learn with experience, kept him from getting bored by refining her tongue techniques, alternating the pace, and steadily milking out his sperm.
"Nnaaaa…"
Opening her mouth, Akeno used her extended tongue as a vessel to pool the semen.
"Nnnn..."
Akeno, receiving the spurting cum all over her face.
"Gulp... goku... gullp!"
Akeno, smiling with crescent eyes while hollowing her cheeks and chugging the cum in one go. With each ejaculation, she showed him a different side.
The technique that initially felt somewhat unskilled was honed over time, and Kazuki's recording captured the entire process of a woman going from her first blowjob experience to proficiency. If anyone ever wanted to learn about blowjobs, this video would serve as excellent teaching material.
At this moment, Kazuki never imagined it. That in the future, young, beautiful girls bearing a strong resemblance to Rias and Akeno would watch this video and think about lovingly pleasuring their beloved 'master' Kazuki with blowjobs.
Unaware of such future possibilities, Kazuki continued to undergo the test.
"Kazuki-kun. I'd like to record the number of times you've ejaculated, so please write the character for 'tally' on my breasts."
Following Akeno's instructions, he used the black marker pen she handed him to write the tally marks indicating the ejaculation count on her tits.
Being made to feel the taboo thrill of defiling her soft, white breasts with black characters caused Kazuki's cock to stand even more gallantly erect.
Erect, ejaculate. Splashed on the face, caught in the mouth.
Repeating these actions over and over, Kazuki became completely captivated by Akeno's breasts.
"Ah... ah... boobs, so many, titty-fuck, the best..."
Kazuki occasionally twitched and convulsed, murmuring deliriously in a daze.
Excessive pleasure had temporarily stripped away his reason, exposing him in a defenseless state.
Yet, his cock stood upright as if imbued with a strong will, trembling pleasurably between Akeno's white twin mounds now covered in semen and tally marks.
"So precious. Please, keep drowning in my charm like this? So you'll come to adore me. So you'll seek me out by instinct. I'll respond to your desires as much as you seek me... Nn, chu."
Akeno whispered to herself, then gave Kazuki a cock-kiss. It was as gentle as a pledge kiss, but her expression was far too lewd to show to one's parents. It was clear that Akeno harbored an even stronger carnal desire for Kazuki than what he felt for Rias and her.
"Ah, I can't wait for the time I accept your cock inside my pussy and receive your seed. While devils have a low probability of pregnancy due to long lifespans, someday, without fail...
"… I will bear many, many precious babies for my beloved Kazuki-kun. Nna, mu, Mmm, mmm, slurp~!"
It seemed Akeno had been fully intent on giving him the reward from the very beginning, regardless of the test's outcome.
"Uoh..."
Kazuki was no longer hearing Akeno's words; his body simply shuddered reflexively as his cock was sucked on.
To endure Akeno's test and receive the reward, he continued to maintain an erection with monstrous endurance, releasing both cum and rationality from his cock.
