"Is there something you wished to talk to me about?" Hyouka questioned, seeing that Ayame had entered her lab room.
Class were out for the day, leaving them the only two students left in the school building for now.
Ayame nodded with a grin, "I have an offer that might intrigue you," She said to Hyouka, her current conquest, "You see, I'm aware you've been attempting to study human breeding, but have been lacking a male subject to.. Research with. Well, I hold a bit of leverage with Tanukichi, and I might be able to get you some time with him."
Hyouka looked over at her curiously, setting down her supplies as her full attention now went to Ayame, "I'm listening."
She grinned, "All I ask in return is a bit of your time for a.. Different kind of research. Some men and women are more interested in each other you know, and some like both genders. The fact that humans are capable of romantic or sexual interest in each at all is worth looking into is it not? So.. we have a little fun together to.. Explore this area of interest, and I get you a little time with Tanukichi. Sound fair?"
Hyouka considered the offer, weighing the pros and cons of agreeing to such a thing. It was against the law certainly, but that had never gotten in her way before and she didn't intend to let it do so now.
She nodded, standing up, "Yes, I believe these terms are more than reasonable." She said, her and expression not leaving their usual deadpan nature even as she began to undress.
Ayame blushed gently as Hyouka began disrobing, "W-wait not right here, someone could walk in on us." She said, though this didn't slow Hyouka's actions.
She allowed her lab coat to fall to the floor and set to removing her school uniform, "This my private office, no one will be arriving here until tomorrow morning. It was an incongruity that you did."
Her tone was not at all changed from her normal speaking even as she stripped completely naked in front of Ayame.
She blinked, looking over Hyouka's body for a moment to take it in. Her body was slender and lean, not much muscle, but not much unhealthy either; likely do to the occasional mad running she had to do to avoid being arrested for her research. And while her chest wasn't massive or anything, she did have the largest breasts Ayame had been with thus far, nearly matching her own in size.
And her legs.. That drew the most attention.
"Shall we proceed?" She asked flatly, yame returning to the situation properly.
"Oh, right." Ayame said, double checking that the door had actually been locked just in case before stripping her own clothing off as well.
Hyouka looked Ayame over, though her expression was more critical and calculating, gauging Ayame's body scientifically rather than lustfully like Ayame had her.
"Interesting." Was her only synopsis, though what she meant or why was left to Ayame's assumptions. Pushing whatever assessment she had just been given to the back of her mind for the time being, she approached Hyouka and brought her into a kiss.
This, strangely, seemed to bring the most response out of her, more so even than the goping of her body that followed immediately after; though said expression was limited to a slight widening in her eyes before they returned to normal as she felt Ayame's hands trace along her body before reaching her breasts and begin fondling her shamelessly.
Rather than being annoyed or bored by Hyouka's lack of response, as Ayame had been expecting herself to be, Ayame was actually more riled up by it.
The desire to break that expressionless shell, to leave it moaning and pleading for more pleasure, it heated Ayame even more as she began groping her harder, squeezing and massaging her modest tits before beginning to pinch and pull at her nipples as well; eliciting nothing more than a few soft groans from her.
Practically holding in a growl, Ayame lowered to her knees in front of Hyouka, pushing her legs open gently and burying her tongue inside aggressively, letting it dig in deep and explore the scientist's inner folds.
Hyouka let out a slightly louder noise, but nothing that satisfied the lust that she had ignited inside of Blue Snow, who grew more aggressive in her actions, moving her hands up and beginning to poke and prod at her rump as wel.
This, confusingly to Ayame is what brought the biggest response out of Hyouka, a loud, surprised yelp from the teasing alone. Hyouka would later explain that her intense response came primarily from surprise than actual pleasure, the idea of what would seem to her as such a non-sexual body part bringing so much sexual pleasure and interest hitting her intrigue button mentally.
But in the moment, Ayame couldn't care less what the reason was, only caring to capitalize on it. She started with just one finger, pushing it in without warning.
Hearing the barely contained moans and feeling the twitching of her body, Ayame picked up the pace, adding two more fingers and pumping all three of her fingers into Hyouka's tight backdoor rapidly, forcing them in knuckle deep to bring out louder, more intense moans from her as Ayame's tongue exploited her being thrown off guard, finding more sensitive spots inside and attacking them mercilessly.
She slid her tongue and fingers out, moving back from Hyouka, who's legs shook reflexively from the sudden halting to the intense pleasure that had been building up in her from Ayame's actions.
"Bend over the desk." Ayame ordered, Hyouka doing so without hesitation or question, pushing her hips back for Ayame, who eagerly parted her cheeks and drove her tongue hard into Hyouka's asshole, satisfied with the near scream it brought from Hyouka as she began to swirl her tongue around inside. Hyouka was reaching her climax within moments of this, which only encouraged Ayame to get more aggressive with her tight, cute asshole.
By the time they were done, Hyouka's interest in alone time with Tanukichi-while still present of course-was greatly eclipled by her new interest in the human body drawing pleasure from otherwise sexual things.
Unknown to Ayame at the time, this would lead to Hyouka studying various other kinks, such as feet and sado-masochism; which Kosuri would prove remarkably helpful in testing, and Otome wonderful for documenting.
Of course, this required bringing her officially into SOX; not that anyone-other than Tanukichi, was complaining.
