[Hmm~♥ The preparation of teaching materials is a mess?]

    “Ugh!!”

    Tenta expressed his disappointment upon discovering the two people completely trapped in the box.

    “Yes? Isn’t this a good Kyobo system?”

    One side is a cadet with no sexual experience.

    On one side is a woman in her 30s who has only had a few experiences.

    Gorton did not find any problems with the teaching materials he had prepared.

    [Tsk! Tsk! Tsk! Why are the toilets who will be teaching sex education from now on wearing clothes?! Hmm!]

    Chaaa!

    Tenta swung his proud tentacle and mercilessly tore the clothes of the two people.

    “Queu!!”

    Siszina had a glimmer of hope that her sister would help her when she saw her clothes being torn.

    “Sister, you look so pretty now…”

    The younger sister’s eyes were shining with interest as she looked at her older sister, whose underwear had become tattered in an instant.

    “Ugh…!”

    [Ohhhh☆ These inverted nipples are precious?!]

    Sisjina closed her eyes because she could not bear the shame as the nipples dug into the inside of her breasts, a complex that she regarded as a secret that she did not want others to see or show, were revealed.

    Two breasts exposed under the gaze of dozens of people and a belly with a lot of fat that has not been trained.

    Between the two legs, which are separated by a fixed device, a gaping crack is letting out the heat trapped under the cloth.

    [Hey~☆ I heard that there are many cadets here who were originally male but were converted to female. So, let me start with a basic explanation of the female body, okay?]

    “Huh?!”

    When the tenta’s tentacle touched the closed private parts of the two people, the cold touch of the tentacle, which was an ectothermic creature, made them flinch in surprise and let out a short scream.

    [People far away may not be able to see clearly, so could you please prepare the magic tool over there?]

    “Ah, yes.”

    Gorton brought a magic tool that had been prepared in advance, just like the box that traps people.

    Tentacles that move freely manipulate magic tools skillfully.

    Jiiingㅡ

    Simultaneously with the unique start-up sound of magical power, light appeared on one wall of the classroom.

    And as the intensity of the light subsided…

    “Ugh?!!!”

    The entire large wall is covered with tentacles that cover the private parts of two people.

    A scene was broadcast in real time showing the labia spreading and opening the vaginal opening.

    It was a prototype using the Academy’s latest optical magic, which had not yet been commercialized.

    “Aaagh!”

    Suddenly, two huge female vaginas appeared in front, causing some cadets to cover their eyes and feel embarrassed.

    This is just an instinctive reflex reaction caused by outdated education that teaches people to feel shame about sex, but in reality, they are peeking at the enlarged vagina with curious eyes through the cracks of their fingers.

    [Look at this♥ Even those who were originally women have never received sex education in such detail☆ From now on, you will have to educate your children and your children’s children, so take notes and listen carefully~]

    The cadets, who blushed at Tenta’s advice but focused their attention on their passionate study, took out their notebooks and began taking notes.

    Some people draw the shape of the two people’s vulva, while others describe it in writing as if describing the shape.

    Each person writes down the greatly enlarged vagina in their notebook in their own way.

    [If you look closely, you will see that these two people’s vaginas look completely different♥]

    Siszina, who had her pubic hair shaved for hygiene reasons, has pubic hair growing like a black dot on her buttocks.

    Sui, who removes her hair by repeatedly plucking it out every time it grows for beauty reasons, maintains a clean buttocks without a trace.

    [Now~☆ This is the part called the labia majora and this is the part called the labia minora?]

    The suction cup tentacles repeatedly extended and contracted as if testing the elasticity of the labia.

    “Keueueuuu be be be making us happy!

    The difference between the two people’s labia is also visible in the way they are spread.

    There is a little bit of flesh on the labia majora due to the accumulation of fat, and the cisterna expands and contracts freely according to the suction cups of the tentacles.

    Sui’s body was thoroughly trained, and the labia minora were stretched more easily than the labia majora, boasting a comparatively widened and colored appearance.

    [What if you go up along the labia minora? Ta-da!☆ A place you can’t miss! Clitoris. There is a clitoris?]

    Siszina’s clitoris, which had no sexual experience, was covered with epidermis, carefully hiding the secret part.

    At some point, Sui’s heart beats out of sexual excitement rather than shame, her clitoris becomes erect, and she and her epidermis show a strong assertiveness towards the sky.

    [Because this is the most sensitive erogenous zone in a woman’s body! ☆ What if you just touch it with your hand to caress it? Absolutely no no!]

    “Hmm♡!”

    As soon as the end of the tentacle splits, needle-thin tentacle strands, which act as fingers, stick out from inside and persistently massage Siszina’s clitoris, relieving the tense muscles.

    In simple terms, more than ten strands move independently as if each has its own will, creating irregular stimulation.

    “Heeui profit♡♡♡!!”

    Pusuk- Pushuuk-

    Even in the humiliating situation where many eyes were focused on her, the pleasure in her vagina steadily built up, and in the end, Shisijina trembled in orgasm, spewing out a tide.

    [like this! You should touch the surrounding area as if massaging it and help the woman’s body to prepare ♥]

    Watching this, Sui, unable to recognize whether she was feeling fear or envy, saw thin strands of tentacles approaching her private parts through the screen.

    [Don’t do it? What about a lustful woman who regularly masturbates by rubbing her clitoris??]

    “Hook♡♡?!”

    Unlike in the case of Siszina, who had no sexual experience, the tentacle strands made direct contact with Sui’s clitoris.

    [You can skip this preparation step.]

    As dozens of thin tentacles persistently torment the tiny clitoris,

    “Heugyuuu)

    Squeak! Pushuuuuk!!

    I couldn’t even last 10 seconds and I climaxed.

    [The act of climaxing is ultimately an exercise that uses muscles, right? Therefore, women who masturbate more often to reach climax experience easier and stronger climaxes?]

    Sui was struck by a strong mental shock that shattered her common sense from the delicate clitoral massage that could only be performed by a thin tentacle that could not be felt by human fingers.

    He, who had the mental strength to continue the fight despite the pain of breaking his bones, had the experience of falling into a climax so easily and losing consciousness for a moment.

    I can’t believe I got hurt.

    Not only was he tortured and incapacitated by Mine, but he even dared to think positive thoughts about Mine, such as ‘These tentacles feel good’ through sexual play.

    I can’t believe she was such a lewd woman.

    [Even if you’re a woman, sometimes you have the luxury of not even knowing what your own vagina looks like? So you need to watch it carefully.]

    The tentacles that had been tormenting the clitoris slowly moved down and pierced the urethra.

    “Huh?!!”

    The sensation of a foreign substance intruding into a hole that exists only for exit, not a hole for entry, made the two people’s half-closed eyes flash open as they climaxed.

    [When trying to penetrate a partner with a finger or a masturbation device, there are cases where the urethra is pierced~☆]

    At the same time, the sucker grabbed the labia minora and opened the vaginal opening wide on both sides.

    [So, instead of putting it in this small hole, you should put it in a slightly larger hole a little lower, so your partner doesn’t have to worry. ☆]

    Fuuuck!!

    “Hmm!!!”

    “Heugyuui♡♡!!”

    As the tentacle was inserted at high speed beyond the vaginal opening without any warning, moans filled with different emotions were spread through the opening.

    Sisjina screams in strong pain as if her hymen is being torn and her internal organs are being pierced.

    Sui’s vagina was already wet with love juice after experiencing one climax, so the surprise insertion caused another climax.

    [As you can see, women who experience penetration for the first time may feel pain and trauma during sexual intercourse, so it is important to first get used to the act of penetration using a stick as thin as a pencil!]

    Soo kung! Phew! Snap!

    “Uuuu!! Ugh!!”

    “Hyaaa♡! Heeuuuu♡!!”

    The G-spot is located between the vaginal wall and the ureter, not far from the vaginal opening.

    The erogenous zone that can elicit sexual excitement as strong as the clitoris is persistently stabbed, and it is not simply a stick stabbing.

    Wiggle- Wiggle-

    “Haeuuuu♡”

    The freely movable tentacles added a bouncing motion as they pierced the vaginal wall, adding stronger stimulation to the G-spot.

    In the end, it didn’t take long for Sijina, who had no experience with vaginal penetration and whose vaginal muscles were not relaxed, to gradually change from screaming in pain to moaning full of excitement.
