Disguise in the health care room

In gym class, a girl fell down right in front of my eyes.

"Ah, it hurts so much... I feel like I can't stand up for the time being... Kashiwagi-kun, can you help me?"

The girl's name is Natsui Mizuki. She is a member of the track and field department. She is number one in the country in the sprint and is a shining star in the track and field world. Her hair was cut neatly short, and her skin was tanned to a healthy wheat color. She doesn't look like she wears much makeup or dress up. She is a classmate of mine who doesn't get along well with others.

I decided to carry Natsui Mizuki on my back and take her to the health room. On the way to the health room, I could feel something soft pressing on my back. It was undoubtedly Mizuki's breasts. Although I didn't pay much attention to it before, her breasts are actually quite plump.

After arriving at the health room, I asked Mizuki to sit on the bed.

"Oh~ why are you injured? I will help you disinfect it now~"

Sitting in the health room is teacher Kaori Arai. She has long soft chestnut hair and a pair of sleepy eyes. She is the kind of gentle beauty who is very popular with boys. In addition to her delicate face, Kaori-sensei also has extremely long legs and plump thighs. I particularly like that about her.

"Okay~ Let me disinfect you~"

Teacher Kaori picked up the disinfectant and prepared to treat Mizuki's wound, but at that moment, Mizuki suddenly stood up, as if she was not injured at all. Then she quickly took off her gym shorts. When Kaori-sensei was still saying "Ah..." in surprise, Mizuki quickly covered Kaori-sensei's nose with her sports shorts. Soon, Teacher Kaori slowly closed her sleepy eyes.

Then Mizuki suddenly threw Kaori-sensei onto the bed.

Mizuki took a deep breath and said, "Okay, no one will disturb us now, Kashiwagi-kun."

"Natsui-kun? Why...?"

"Huh? Why? This kind of thing is obviously just for sex. Look, I have taken off my sports shorts, and everything underneath is exposed."

Natsui Mizuki's private area was not tanned, and the slightly pink part was slightly exposed. Mizuki's expression was completely different from the bright smile he usually wore in the classroom, with a hint of lewdness and a strange smile.

"No, you are Instructor Tachibana."

"Hehe, I found it too late♡."

With that said, Colonel Tachibana quickly transformed into Natsui Mizuki, punched me in the abdomen, and pressed me on the bed. Then she quickly took off my pants and straddled me. When she took off her gymnastics uniform, the two pieces of flesh on her chest swayed.

"Gu (swallowing)...where is the real Natsui Mizuki now..."

"Oh, the real me? The real me is in the instructor's room now. I gave her the powerful aphrodisiac we recently developed in the military, and now she should be immersed in the pleasure of masturbation. After having enough fun, She probably can’t remember anything. Ah, I have to clean the instructor’s room afterwards. It must have been a mess from the love juice and saliva. Hehe♡”

Looking at the smiling instructor who looked exactly like Mizuki, I felt very scared.

"Don't be so afraid. I am your classmate, Natsui Mizuki, right? These breasts, this waistline, these hard abdominal muscles, these tight buttocks, and these slender legs are all real. Just feel free to enjoy it. But since you’re so scared, I guess you can’t resist. Hmm♡”

My fully erect lower body penetrated deeply into Rui Ji - no, the instructor's pussy, and started a rhythmic thrusting movement.

"Look at you, you didn't even notice the fake classmate. Kashiwagi-kun, you are nothing more than that. Come on, give me a kiss♡."

Being wrapped by the soft and tight pussy of Mizuki, the instructor, and her soft lips, I couldn't help but close my eyes. How I wish this dream like heaven and hell could end soon. While I was thinking this way, I was obsessed with Mizuki's strong athletic body.

After a while, I opened my eyes.

then……

"Hmm♡Hey~♡How does it feel inside the teacher~, is it comfortable~♡"

"Kaori-sensei…………!?"

The teacher Kaori sitting on the bed in front of her is actually an instructor in disguise. She kept swaying her hips with a slightly sleepy look. The flowing chestnut hair swayed with the movement, and the plump breasts swayed with it.

"You know~, the teacher especially likes a young and energetic cock like yours♡Hurry up and move it~♡Hurry up~♡"

No, she is an instructor. Even though I told myself so, I was almost defeated when faced with this silky touch. Unlike Mizuki's tight feeling just now, Kaori-sensei's body wrapped me tightly like cotton.

"Gu..."

I tried hard to endure, but in a moment of relaxation, I reached an orgasm involuntarily.

"Hmm~? Oops~? You are satisfied without satisfying the teacher~? Is this really okay~? Seriously~, if a killer disguised as a health teacher came~, wouldn't you be killed immediately? Did you drop it~? It seems that a punishment is needed~. Then, put your hands on the wall and raise your butt~.

I followed the instructor's instructions.

"Bite your teeth."

“……！”

The instructor, who had transformed into a naked teacher Kaori, started kicking my buttocks with her bare feet. Being kicked in the butt like this by that gentle Kaori-sensei gave me a wonderful feeling. Now the real Kaori-sensei is still lying on the ground, and the fake Kaori-sensei is continuing to punish me. After that, the instructor who became Kaori-sensei and I walked to the instructor's room.

There, Mizuki was indulging in masturbation. Her wheat-colored skin was already wet with love juice, sweat and saliva. Even when I talk to her, she just makes meaningless noises like "Whoa~?" or "Whoa~?" and keeps playing with her pussy.

"Haha, she has become a masturbation maniac~. Then let her faint~, come on~"

"Ugh..."

Rui Ji lost consciousness under the instructor's knife. Then, I dried Mizuki's body, put her uniform on, and walked to the health room. In the health room, after I told the real Kaori-sensei who had just woken up about the situation, she came to the instructor's room. The instructor had now transformed back into Tachibana Meicheng.

"Oops~, maybe it's anemia~." Teacher Kaori said as she picked up Mizuki and walked to the health room.

I couldn't help but feel a little embarrassed when I thought that I had experienced the private parts of the health teacher and my classmates, but at this time, my lower body was bulging under the uniform.
