It's only okay with me

"Because... uh, that's only how men and women greet each other... if their surname is Okuma," Tanukichi said hastily.

"What? That doesn't make any sense," the boy sitting across from Anna complained.

"It's, uh, an old Japanese tradition most people have forgotten," Tanukichi replied. "I would have told you guys about it earlier, but it just didn't seem like the right time."

"That's... just stupid." the boy replied before turning back to Anna. "Hello, Anna, my name is Osaki."

Tanukichi looked to Ayame desperately as the boy moved to kiss Anna, to which Ayame gave a subtle nod and shut her disruptor phone.

Just before the boy was about to bring his mouth to Anna's waiting lips, necklace he was wearing suddenly let out a loud alarm that stopped him in his tracks.

"Alert! Alert! Indecent behavior!" a robotic voice shouted as red lights blinked on the monitoring device. "The morality police have been alerted!"

"No! No! I can't go to prison!" the boy hastily tried to take the device off. "I'm too young! I-I had a bright future!"

Before he could get the device off, several campus security guards had stormed into the room and began to drag him off. No one ever doubted the morality police's monitoring devices, so there was doubt that he would spend at least a decade in prison, if not the rest of his life.

"Noooooooooooo!" His voice trailed off down the hallway as the students all looked on, horrified.

"My word... Mr. Okuma... you just saved me from doing something terribly indecent!" Anna bowed her head at Tanukichi in thanks. "I owe you my life!"

"Oh, jeez, it was nothing." Tanukichi rubbed the back of his head in embarrassment. "I'm just being a morally upstanding citizen."

Ayame interrupted Tanukichi with a cough and a glare.

"Forgive me, Mr. Okuma, but you have a presentation to finish," she reminded him.

"Oh, right!" Tanukichi hastily returned to his podium. "Uh... for everyone else, a simple bow, handshake, or 'hello' will do. If any of you are ever confused about whether or not a greeting is indecent or not, just let me know."

The classroom broke out into grateful applause before the students began to file out one by one.

"Phew... that was close..." Tanukichi moved to follow them, only for someone to step in front of him and land a kiss directly on his lips - thankfully not followed by the sound of an alarm. "Mmmm!"

He didn't get a good look at her before the kiss started, so he wasn't sure who it was he was making out with at first. However, there was no mistaking the tired, purple eyes that started back at him; it was Hyouka Fuwa. Her tongue tasted vaguely of coffee as it entered his mouth and began exploring. Its movements were not overly sensual - it was more like her tongue was studying his mouth, learning every nook and cranny as she also got used to the sensation of kissing someone.

He had hoped that she'd pull away on her own, but Hyouka seemed to want to keep this going as long as possible, and her grip was surprisingly strong. Without much choice, Tanukichi finally began to kiss back, surprising the girl as he caressed her tongue with his. He could feel her body warm up a degree or two, and her pupils dilated in surprise. Tanukichi wondered if was the same during his first kiss mere moments ago, but he pushed that slightly-embarrassing thought from his mind.

Finally, the kiss ended and the student scientist allowed Tanukichi to breathe freely again.

"Hello, Mr. Okuma," she greeted as she wiped his spit from her lips. "It is nice to see you again. Please forgive me for not greeting you in the proper way the first time we met. I assume that is why you did not answer my question the first time we met."

"Uh... don't worry, it's fine," Tanukichi replied nervously as he thought "That's not why I didn't answer you anyways..."

"Now then, I have another question that I would like to ask you." Hyouka reached into her pocket and pulled out a Card Cutie, this one featuring a girl with blue hair winking as she spread her pussy lips for the viewer. "Do you know if a woman's v... flower has anything to do with reproduction?"

"W-what kind of question is that?" Tanukichi stammered.

"A logical one." Hyouka pointed towards the labia majora of the woman in the picture. "At first I thought that babies grew from these 'petals', but that does not explain why the bellies of expecting mothers swell to enormous proportions." Her finger moves to the woman's clit. "Then I thought that this might be part of a growing baby, but then I realize that I have a protrusion like this one too, and I am relatively certain I am not pregnant, although inspecting it made me feel very strange." Her finger pointed to the woman's urethra next. "We are taught the function of this hole in class, though they refuse to name it, and its function seems incompatible with baby making so I believe it is safe to rule that out." Finally, her finger landed right the mouth of the woman's vagina. "That only leaves this hole as a possibility. It may seem too small to fit a baby inside, but it seems to serve no practical purpose on its own besides discharging blood at regular intervals. So please, Mr. Okuma, can you confirm or deny my theory?"
