Chapter 28: Mizuki's Anal Training II

Chapter 28: Mizuki's Anal Training II

Mizuki slipped into the classroom just in time and stood in front of her chair, swallowing nervously.

(If I sit down normally, this is going to be bad...)

If she sat down normally, her Ass would press against the chair, pushing the object inside her even deeper.

(It's already at its limit, pushing it in further would be suicide...)

Mizuki positioned herself so that her Ass didn't touch the chair, sticking it out instead.

The pressure was significant, but still manageable.

(Just two more hours... Just sit like this and wait for class to end... I can do this. I can do this...)

She repeated these thoughts to herself, and indeed, the classes passed peacefully.

(It seems manageable... I'm getting used to this feeling, but it's strange... Am I really feeling pleasure from having this thing inside me...?)

The last math class of the day was coming to an end, and Mizuki, who had gotten used to the feeling of pressure, seemed to have some free time and was stimulating herself while fidgeting and moving her ass, giving her pleasure.

In other words, Mizuki is a perverted female student who wears an anal vibrator and indulges in masturbation during her class.

"Miss Shiina... Miss Shiina..."

(Ah... it feels good... My Ass feels good... Wait...)

"Yes!"

Fully immersed in her own world, Mizuki only realized her name was being called by the teacher when she hurriedly responded.

She noticed the gazes of her classmates on her, with some of them giggling, and her face turned bright red.

"What's wrong? You seem to be spacing out. I understand you're tired from morning practice, but please concentrate until the end since there's just a little bit left."

"Yes... I'm sorry."

Mizuki apologized, but inside, she was more concerned about something else.

(Did they find out? I was moving my hips... I thought I was being discreet, but were my movements too noticeable?)

This is her biggest concern at the moment.

She glanced at everyone's expressions, but there didn't seem to be any classmates looking at her with contempt.

"Alright, Shiina-san, please come to the front and solve this problem."

Mizuki, who had regained the ability to walk somewhat normally, moved to the front of the classroom as instructed by the teacher.

(Everyone's watching me... They're all looking at me with something big inside my butt...)

Mizuki felt everyone's eyes focused on her Ass, which made her both embarrassed and aroused. As she moved her body to write equations on the blackboard, she subtly began to move her hips in a way that wouldn't be noticed.

(Everyone, look! Watch me doing anal masturbation, watch more!)

While reveling in the pleasure, Mizuki used all the time allowed for solving the problem to enjoy her masturbation.

Just as she finished solving the problem and turned to return to her seat...

"～～～～～～～～～!!!"

She felt a powerful stimulation in her Ass and collapsed on the spot.

(No way... the vibrator... it's vibrating... I came...)

Mizuki hadn't considered that the vibrator might start vibrating, and the unexpected stimulation brought her to an intense climax.

It was thanks to Mizuki's strong willpower that she managed to suppress her voice.

However, her helplessly ecstatic face was visible to everyone.

"Shiina-san, are you okay?"

"Ah... haha... I'm okay... huh?"

She tried to stand up, but couldn't muster the strength.

"Mizuki! Are you okay? Here, lean on me."

Akane quickly rushed to Mizuki's side, lending her shoulder to help her stand.

"Thanks... Akane..."

"It's okay... um... from Lily?"

"Yeah... Lily-sama made me come...♡"

Akane looked at Mizuki with a pained expression but said nothing more, escorting her friend back to her desk.

As if signaling the end of Mizuki's spectacle, the chime rang throughout the classroom.

"Alright, Mizuki, show them to the two."

At the end of the lesson, Mizuki, accompanied by her usual group, escaped to the nurse's office.

"Yes, Lily-sama."

Lily told Mizuki to take off her skirt and lower her panties. Mizuki then got on the bed, positioning herself so that her butt was prominently displayed.

The two girls, unaware of the situation, reacted with a mix of surprise and amazement.

"Have you had that in all this time?"

"Yes, since lunchtime."

"What exactly do you have in there?"

"It's called an anal vibrator. It's an adult toy that makes you feel good through your butt."

Mizuki answered their questions clearly and confidently.

Her face radiated a mix of pride and superiority.

"Such a thing..."

Akane stared intently at the black object protruding from Mizuki's Ass.

"Could it be that Akane is jealous?"

"Th-That's not possible. Something so gross..."

Despite her words, Akane couldn't take her eyes off it.

Akane, who climaxed daily during bowel movements, fully understood the pleasure it could bring.

"What about you, Aya?"

"I'm jealous... I can't believe you get to experience something so wonderful..."

For Aya, who was currently denied pleasure, the sight was too dazzling.

Ignoring Akane's pained glances, Aya watched Mizuki's butt, shifting restlessly.

"Mizuki, how was it? Did it feel good in your butt?"

Lily asked while sitting on the bed, gently stroking Mizuki's head.

"Lily-sama, it felt amazing...♡ I didn't know it could vibrate...♡"

"You came in the end. It's impressive you didn't make any noise. Well done."

Mizuki, looking like a dog praised by its owner, basked in this reward with a blissful expression.

"Most people probably thought you were feeling unwell, but a few must have realized you came."

"No way...♡ That's so embarrassing...♡"

Though she said it was embarrassing, Mizuki, in her state of reward, didn't really care.

"Since you worked hard and had fun, I need to give you a reward. Come here."

Lily said, patting her own lap. Mizuki, as if drawn, buried her face there.

Having her head stroked was already a reward, but this was an extraordinary one.

(Getting such a reward... Lily-sama's lap feels so good...♡ Soft and smells nice...♡)

The pet, enjoying her blissful time with a wagging Ass was watched by three pairs of eyes, each with their own thoughts.

"Lily-sama, can I take out this vibrator now?"

As Lily was about to leave the nurse's office, Mizuki asked.

"Why?"

"Why... I have club activities now..."

"Just go as you are."

"...Huh?"

Lily spoke as if it were the most natural thing in the world.

Mizuki's long day was far from over.
