He reached out and grabbed the defenseless pink points moving up and down before him and she let out a groan of surprise.
"Is something…the matter?"
"No, so continue.
He rolled her areolae around as he gave her a command.
She seemed to hesitate, but she finally nodded obediently and resumed bouncing her breasts.
"…"
He wanted to tease her in some way, so he began an even more indecent attack on those bouncing breasts.
Touching her again after ten days confirmed that this was the same girl he had loved on that day.
Her nipples grew more sensitive the closer to the tip he got, but she was also weak at the border with the areolae at their base. Her ears, neck, nape, armpits, back, and sides were also sensitive. As he traced his fingers across her, her entire body wriggled.
"N…nhh."
When he stroked her hair, she breathed from her nose like a relaxed kitten.
When he obscenely stroked her areolae, he could see the butt twitching inside her black swimsuit. She also began pressing her breasts more strongly against his penis.
He could feel the rhythm of her breathing quicken as her breaths tickled his legs. She clearly wanted him to grope her bust until they lost their shape entirely.
Eliciting that indecent reaction gave Mutsuki a slight sense of satisfaction. But at the same time, he could not forgive himself for falling back in love with the entranced look visible in her upturned eyes.
"Is someone there?"
Mutsuki heard the door slide open and heard the voice of the school doctor who ran the infirmary.
Oops, he thought. He had been so focused on being alone with Machina that he had completely forgotten they were at school. He started panicking.
"…Over here."
But Machina reacted quickly. She immediately stood up, fixed her half-removed swimsuit, and signaled for him to hide behind the shelf by the bed.
The shelf held new sheets and tubs for vomit, so it was quite large and the surrounding area was divided off with a curtain. There was plenty of room to hide a single person.
"Oh, so there is someone. What's the matter?"
Just as he had hidden, the school doctor peeked in through the gap in the curtain partition.
"…Feeling anemic. I want to rest a little."
"Oh, the pool, huh? Yeah, that's tough for girls. Wait there."
Fortunately, School Doctor Shiromiya Kaede was a woman and wellknown for being kind. Seeing a female student in a swimsuit was enough to believe the claim of anemia without really checking.
After sensing the teacher leaving the partition, Mutsuki peeked out.
"…"
His eyes stopped on Machina's backside.
Quickly pulling her swimsuit back up had caused it to ride up on her small butt.
Unlike her chest, her butt was small and tight. The flowing roundness of a marble statue was pressed in by the edge of the swimsuit, emphasizing the feminine softness of her flesh.
(Her ass is really sexy too.)
He had forgotten with all the focus his classmates had given her breasts, but her nice hips and long-legs were also as beautiful as the average model's.
"!?"
He naturally reached out to the delicious butt sticking out in front of him.
He ignored Machina's widened eyes and lewdly groped it. He knew someone was right on the other side of the partition, but he could not stop himself. In fact, her troubled expression worked up his sadistic side.
"Fujita…-kun."
She tried to rebuke him in a voice almost too quiet to hear, but he continued pushing his fingers and the swimsuit in between the two cheeks.
Unlike Micha's squishy butt, Machina's had a pleasant elasticity.
He could not help but dig his fingers into it. He rubbed it, pinched it, and kneaded it.
"Hh…hh…"
Machina's breathing grew heavy once more as his fingertips reached her thighs as well.
"Fill this out."
The teacher was back. Luckily, she did not peek inside, so Mutsuki was able to zip back behind the shelf. Still, he kept his hands moving along her erotic flesh as he did so.
Machina pressed her hips against the shelf to keep his hands from being seen – essentially sticking her butt right in front of Mutsuki's eyes – as she filled out the form needing her class, name, and symptoms. And then…
(…Hm?)
She began twisting her hips in irritation as he thoroughly groped her.
With her butt so close, he breathed in through his nose and detected a familiar scent.
"Okay, you can rest now. …You're Ibekusa from Class A, right? Where are your clothes?"
"…In locker #2 of the outside girls locker room."
"Got it. I'll bring them here, so don't go to sleep until you change out of that wet swimsuit."
She was a sloppy but good teacher, so she handed Machina an iron supplement and some water before leaving the room.
After hearing the door close, the girl quickly moved away from his indecent caress.
"D-don't do that."
She fixed her swimsuit that had nearly become a thong and she lowered the ends of her thin eyebrows.
Mutsuki smiled bitterly when he realized this was his first time seeing her angry, but it did not slow him down any. In fact, his cheeks twisted upward at the rare expression.
"Don't do it? Even when it's done this to you?"
Before she could stand up, he wrapped his hands around her fleeing hips.
He embraced her as she pitched forward and brought his hands to an even more risqué depth. As he rubbed all over her inner thighs, her slender shoulders twisted and she lost the strength to fight it.
"Um…"
"You're getting horny on the inside too. …Keep an eye out in case the teacher comes back."
Even through her swimsuit, she was obviously melting. She had definitely been burning up ever since the titjob and a sweet and sour feminine smell was rising from deep within her round butt.
Her belly was unbelievably tight, so her hips created a sharp contrast and her butt really stood out. That tightened texture was irresistibly cute, so he traced his tongue along it.
"Ahh…"
Machina leaned forward in surprise.
She was now clinging to the metal pole for the partition and her entire lower body – from her small and adorable butt to her toes – was presented before the boy crouched behind her.
"I'm gonna take a look."
That short comment sounded like a command and he pushed aside the swimsuit's crotch.
The soft mound of her hidden palace was exposed below her white butt. The swollen flower petals had seductively spread to reveal the pale inner flesh, but the undeveloped inner folds did their best to hide the central hole.
Mutsuki gulped.
