Lala is a little worried because her panties get dirty with the slimy liquid that overflows from her crotch every day. She feels embarrassed to ask her mother about it, so she goes to the hospital secretly. Dr. Kagami, a perverted doctor who loves beautiful girls, examines Lala. Taking advantage of Lala's lack of sexual knowledge, he performs a very embarrassing examination...Lala tries to close her legs immediately because she is embarrassed about having her crotch examined. Dr. Kagami calls a young male doctor to help, and holds Lala's legs open with great force. Lala is confused by her burning crotch, even though she is about to cry because a man has seen her naked for the first time. Seeing Lala's condition, Dr. Kagami also escalates. He pretends that a vibrator is a dilator (the name of an instrument that expands blockages in blood vessels, vaginas, intestines, etc.) and stimulates Lala's small vaginal opening with vibrations. The embarrassing examination of her genitals is repeated relentlessly, and Lala-chan's ecstasy reaches its limit, and she can no longer endures it and loses control... With the approval of her parents, Dr. Kagami is able to perform a sexual examination on Lala-chan under the pretext of hospitalization for an examination. He visits Lala-chan's hospital room with a young male doctor to perform the examination. Dr. Kagami proposes a curriculum to help Lala-chan, who has little sexual knowledge, learn more about male and female sexuality. When he orders the male doctor to expose her lower body, the male doctor immediately takes off her pants and underwear. Lala-chan is stunned, her eyes wide open at the strangeness of the adult penis. "What do you think, Lala-chan? This is your first time seeing an adult man's penis, isn't it?" Dr. Kagami instructs Lala-chan, who nods with her eyes glued to the penis, to slowly take off her clothes. The male doctor's penis becomes as engorged as he can at the sight of her embarrassment as she fidgets and unbuttons her pajamas. "Isn't it amazing? A girl's body is a field for inserting this into her vagina, squeezing out the seeds, and growing the next generation... the babies. Lala-chan's slippery fluid is a lubricant for inserting this into her vagina," Dr. Kagami explains about sexual intercourse while playing with the doctor's male organ. While showing off his petting, he urges, "Lala-chan, your face is turning red... Check with your own fingers what kind of changes are occurring in your genitals." With her eyes glued to the adult acts unfolding before her, Lala-chan slips her fingers inside her panties. Just a light touch makes her twitch and twitch! She reacts violently. "Why don't you touch me too, Lala-chan? "It's twitching, but don't be scared lol." Lara-chan reaches out her hand timidly, but curiously, with tears in Hitomi. "You're good at it, Lara-chan. Men will be even happier if you lick this with your tongue. Try it," Lara-chan instructs on fellatio. Lara-chan is scared, but she tries her best with her pretty lips. The doctor can't stand the movement of Lara-chan's lips, which become more and more intense as she immerses herself in the secret act of an adult, and ejaculates in her mouth. "It's bitter..." Lara-chan distorts her expression. "Actually inserting it is prohibited for hospital compliance reasons, but it's okay if you just place it against me, so ○○-kun, try pressing your head against Lara-chan's vaginal opening... Is it okay with you, Lara-chan?" Despite her young body, the urge to be penetrated is swirling violently, so Lara-chan nods. The thick penis is rubbed violently against her pretty labia, and it's a sex simulation training session. In the end, he ejaculates forcefully in front of her. Next, we ask an inpatient with sensitive nipples to cooperate. By actively making the man feel good by playing with her nipples, Lala deepens her understanding of men's sexual responses. A counseling session with an inpatient with sensitive nipples, who is also an authority in psychiatry, reveals that Lala's aversion to sex is caused by the sexual molestation she experienced in her childhood, which has become a trauma. Following his advice, we decided to carry out a ``re-education program'' to overwrite the Kokoro wounds by having Lala experience a simulated childhood. We set up a simulated nursery school in one corner of the ward, with Dr. Kagami as the nursery teacher and the male actor doctor as the older child, and begin role-playing to help Lala return to her childhood. While drawing pictures and playing with origami, she wets herself in her pajamas... We take care of Lala's wet panties and help her wear a disposable diaper. Embarrassed that she is the only one wearing a diaper, Lala begs her older brother to wear one too. With the help of Kagami-sensei, she puts a disposable diaper on her brother. But her brother, who likes Lala, gets his penis hard while she is taking care of him. It gets hard and looks painful. Just like what she learned during her stay in hospital, Lala plays with it with her fingers and licks it with her tongue, making him pee white liquid. In fact, while taking care of her brother, Lala secretly pees into the disposable diaper...
