“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.
Seeing the shameful flesh he had deflowered ten days before filled him with dark desire.
That place had become his once before.
He was its conqueror.
“Ahhh… N-not so…sudden…”
When he mercilessly stuck his middle finger into the wet crevice, the girl gave a shrill scream as if a jolt had run through her.
“…d”
Mutsuki’s cheeks loosened. Nothing delighted him quite like the cries of that normally silent girl.
He brought one hand to her inner thigh from the front. He spread the flesh covered in sticky nectar and gently grabbed her clitoris.
“Hyahhh…ahh…nkhhh… Like…I said…”
The school doctor could return at any moment, so Machina attempted to complain.
“Fujita…-kun…. I really…want you to stop…ahhh.”
“No, you don’t. Your juices just keep dripping out.”
When he sucked those juices from her thigh, she could not argue back.
“You need…need to stop…”
She was leaning against the partition, so she naturally ended up presenting her butt to him. She moved her hips to soften the stimulation, but she could not escape when he had her hardened maiden’s bead in his grasp. In fact, she soon began straightening her legs, giving him the best angle to tease her from.
The boy brought his face in close and discovered another teasing point.
“Hey, Ibekusa-san.”
He released her body and brought one of her hands from the pole to her own butt.
“Pull that back for me.”
He whispered to her with a slightly commanding tone.
She did not seem very willing, but she did as he said when he started wetly rubbing her clitoris which had grown so erect it tingled down to the base.
She spread her plump butt, pulling the navy blue swimsuit aside.
“Ah…nn.”
Letting the air in between the cheeks must have been embarrassing because she twisted her upper body and could be heard breathing from her small nose.
Deep inside the beautiful heart shape of her butt, an adorably enticing hole squeezed shut to form wrinkles.
“Eh…? Hyah… F-Fujita-ku…nn!?”
He had tried this on Micha the day before but been interrupted by Ange. Without permission, he reached his finger to that slightly wet bump.
“Ah…um…ahhn.”
The crimson winkles came together at even intervals and lifted the small hole up a bit in a donut shape. He had guessed it when it twitched worriedly just from the cold air reaching it, but he was sure of it once he traced his finger along the edge of the dark pink hole and all of the small wrinkles reacted.
She was sensitive here.
“Ahhhhh~~ Nn…!”
He parted her butt that looked as juicy as a freshly-picked white plum and he sucked at the central indentation.
His soft tongue dug into her anal flesh and licked the wet ring. Machina arched her back so much he thought it would break and she let out a scream shriller than he would have ever imagined from her.
But that reaction only caused her giant breasts to bounce up and down through her glistening school swimsuit. She was unable to shake his grasp on her hips.
“Um, Fujita-kun. That’s…that’s the wrong hole.”
“No, it’s not. It feels good here too, doesn’t it?”
She may not have been aware that excretion point could be used for a caress because she seemed intensely confused as the boy’s tongue skillfully worked its way around. But…
“…Nn. Ha ha. You’re really sensitive here.”
“Ahhhhhhh…”
Once her hard sphincter softened, her reactions were even more indecent than Micha’s.
When he teased the soft pink flesh beyond those wrinkles, the sphincter located about a centimeter deep loosened. He immediately stuck his tongue inside.
“Kfaaaaahhh… M-my butt… It…it feels weird…”
He stirred up her anus like his tongue was a drill making meringue and the girl produced meaningless moans like she had completely forgotten how silent she normally was.
(I wonder if hers can spread wider than Micha-san’s.)
Continuing to lick that soft anal flesh was an attractive option, but his interest turned toward the ring of harder flesh nearer the entrance. He poked at the ring with the tip of his pointed tongue from inside and out. He also rubbed the body of the tongue roughly against it. Altogether, he employed an even more thorough assault than the one that had driven Micha mad.
The deep crimson flesh finally seemed to admit defeat and opened wide.
An indecent scent wafted out from within the dark hole. There was a faint hint of a familiar fruity scent, reminding him that she often ate apples.
“Ahh…ahhhhn… No, no…”
Tears of embarrassment filled Machina’s eyes, but her body was already a slave to him as his tongue moved several centimeters in and out of a hole meant for excretion.
She fell onto all fours while still holding the pole and she began pressing her butt up against his face. She was telling him to penetrate her anus even deeper.
And just as she was entirely immersed in anal pleasure…
“This might be a little tougher.”
“Eh…? Ah…no…ah… Nn~~~~”
He redirected his tongue to the area around her anus and stuck his middle finger into the central hole.
Based on Micha’s reaction the day before, he thought this might be too much for Machina, but her excretory flesh tightened pleasantly around the finger.
“Ahh…ahhhh…”
(What a sexual look on her face… I never thought messing with her butt a little would make her look like that.)
Her usual expressionlessness made the melting expression all the more noticeable. And based on that, he guessed he could make this tight hole even softer. A tingle ran down his spine.
(Ibekusa Machina…)
The dark feeling that had appeared in his chest earlier was growing stronger.
He did not know what it was, but it grew larger and stronger the more his actions threw Machina into disarray and the more she submitted herself to him.
(She’s mine.)
A thrill welled up within him.
But then the door slid open again.
“I’ve got your clothes.”
Almost exactly like before, they heard the teacher’s voice and the boy quickly hid behind the shelf.
“…U-um.”
Machina tried to say something, but it was too late. Doctor Shiromiya brought the uniform over and peeked inside the partition.
“Are you up? …Your face is pretty red. Is something wrong?”
“~~”
More than just red, the girl’s forehead was covered in sweat, so the school doctor tilted her head.
Instead of just being taciturn, Machina could not even open her mouth, so she shook her head to say nothing was wrong.
To make matters worse, Mutsuki was still pushing at and massaging the excretory flesh that was writhing from the foreign sensation. He rubbed his saliva all over the entrance and dug deep inside. The same finger technique that had easily brought an adult like Micha to climax were building up this young girl’s sexual pleasure.
“Hh…hh…”
The girl used a mind of steel to erase her expression and attempted to ignore the sticky anal pleasure.
“Hm? Well, whatever. Once you’re changed, get some rest.”
Luckily, Doctor Shiromiya closed the curtain without noticing Machina’s condition. Namely, the swimsuit riding up oddly in the crotch and the nipples standing visibly erect even through the elastic material.
Machina’s hips gave out and Mutsuki rushed out to catch her.
