Chapter 29: Mizuki's Training - III

Chapter 29: Mizuki's Training - III

Alone in the track and field club's locker room, Mizuki was checking her appearance.

She was wearing a sleeveless shirt on top and running shorts on the bottom, her usual gray practice outfit.

"Ugh... It's still noticeable... This is definitely going to be obvious..."

The back part of her running shorts was slightly bulging.

It wasn't noticeable from a distance, but up close, it might be seen.

Wearing a jersey was an option, but her master probably wouldn't want that.

"I don't feel like I can exercise like this... but it's Lily-sama's order, so I have no choice..."

To be honest, walking was hard enough, and she wasn't sure if she could handle intense practice, let alone warm-up jogging or stretching.

Another troublesome thing was that this track and field club had a lot of physical contact.

Things like linking arms or hugging were common, and sometimes breasts or buttocks were squeezed.

It was proof of their close relationship, and Mizuki had gotten used to it, but today she couldn't afford to be touched.

She wasn't sure if she was expected to complete her club activities, get caught and feel embarrassed, or something else, but for now, she decided to fully commit to her club activities.

"But still... mm... I really can't move well..."

Twisting her hips left and right, she left the locker room with a wry smile.

(Ugh... It's tough... Three more laps...)

She was jogging alone on the track because she arrived late.

It was more convenient that way, but she couldn't get the power into her lower body, making her much slower than usual.

Moreover, she was careful not to let anyone get behind her, which probably made her movements look very suspicious.

(But... gradually... I'm getting used to it...)

Although her speed wasn't improving, she was getting somewhat used to the stimulation and pressure.

Impressed by her own adaptability, Mizuki began to hope that she might get through her club activities like this.

(This... vibration... is starting to feel kind of good...)

The vibration that resonated through her intestinal walls every time her feet hit the ground had somehow turned into a pleasant beat.

It felt like her entire body was vibrating through her spine.

Her face was flushed, and small moans began to mix with her breaths.

Of course, it wasn't just the running that was heating up her body.

"Hah... phew... ahh... mm..."

(Ah... it's really starting to feel good... The vibration is spreading throughout my butt, and it's stimulating my pussy too...)

Mizuki's thoughts had become entirely focused on how to make herself feel good while running.

She forgot how many laps she had left and was solely concentrating on this new sensation.

...Not noticing the figure approaching from behind...

"Mizuki, you're slow! What are you doing, taking it easy?"

"Hyiiiiiii!!!"

Mizuki, who was smacked hard on the butt by a female student running up behind her, trembled all over from the intense stimulation and stood still on the spot.

(I messed up... I wasn't watching behind me at all... Ah, it's bad. I just came from that...♡)

Should it be called a silver lining? Because the hit landed on the lower part of her butt, the hard object barely avoided contact with the hand.

However, Mizuki, who had climaxed intensely, was unable to muster any strength and couldn't move.

Her running shorts showed a stain that was clearly not sweat, expanding its territory.

"Yu... Yuka... hi..."

"Mizuki, what's wrong? Are you okay?"

The girl called Yuka turned around and looked at Mizuki with concern.

If she were to get behind her now, it would be bad, but that worry seemed unfounded.

"Ah... yeah, I'm just not feeling well... I was planning to take it easy today..."

"What? That's serious! Your face is pale, and you're sweating a lot. Do you want to go to the infirmary?"

"No... it's not that bad... I'm okay..."

"You're not okay! What if you get hurt by pushing yourself too hard? It's important to rest properly when you need to. I'll explain to the coach, so take the day off."

Before Mizuki could stop her, Yuka had already left.

Mizuki realized she had made a huge mistake.

She wouldn't be able to participate in club activities today.

(No way... Lily-sama's orders...)

Mizuki had no means left to carry out her master's orders.

It was a game over here.

(What should I do... How do I explain this to Lily-sama...)

Not wanting to stay there and risk having the foreign object in her butt discovered, Mizuki trudged away and headed towards the school building.

She wasn't sure if this would satisfy Lily, but it certainly wasn't a perfect score.

(What if she loses interest in me and abandons me...)

While she doubted it would come to that, she couldn't shake off the anxiety once it surfaced.

(Ah... there's Lily-Sama. Has she been watching me the whole time...)

Seeing Lily looking at her, she was led to a hidden spot beside the school building.

"I'm sorry, Lily-sama. They stopped me from continuing club activities."

"It seems so. I was watching, and it looked quite unnatural. Either way, it would have been impossible to continue. I might have been a bit too unreasonable."

With Lily's words, Mizuki's earlier anxiety surged, and she prostrated herself, begging for forgiveness.

"Lily-sama, I am so sorry. I will do my best to satisfy you next time, so please don't abandon me."

"Huh? Why would it come to that... Oh, it's about Aya."

Confused by Mizuki's sudden plea, Lily understood the reason and spoke to her in a reassuring manner.

"That was just to make Aya understand her place. As long as you, Mizuki, act with the proper awareness of being a slave and follow accordingly, I'll always treat you well and give you rewards if you do well. Though, it depends on my mood."

Mizuki realized that she had been overthinking things.

"Besides, I know I pushed it a bit too far this time, but even so, you tried your best to follow my orders. I was very satisfied with your performance today, both in the infirmary and during class. There's no way I'd abandon such an excellent slave."

"Lily-sama..."

Lily knelt down and gently hugged Mizuki, who was still in a prostrate position but had lifted her face.

Moved by her master's kindness, Mizuki shed tears in her arms.

"Now, I'll remove the vibrator, so turn your butt towards me."

"Yes! Lily-sama!"

Renewing her loyalty to her master, Mizuki proudly raised her butt high.

"You're really energetic... Hey, Mizuki, did you know that removing an anal vibrator feels the best?"

"Is that so? Ah...♡ Ahhh...♡ It's being pulled inside...♡ It feels so good...♡"

Lily slowly pulled out the vibrator, and Mizuki savored the pleasure, almost like a bowel movement.

"By the way, Mizuki, have you been masturbating on my chair?"

"Lily-sama noticed... ugh...♡"

Lily twisted the half-removed vibrator back to the base.

"Of course I did. Who do you think I am? For a succubus, it's easy to pick up the scent of a female in heat. But, receiving your arousal marks every day made me wet. It was like being marked."

Lily spoke to Mizuki with a dreamy expression.

(The sudden thrust of the vibrator feels good... No, I mean, she noticed, but I'm glad she liked it...)

"This vibrator is like a dog's tail. You perform tricks well, and you're an excellent bitch."

"Woof woof woof♡ Woof♡"

Overjoyed by Lily's words, Mizuki imitated a dog's bark, expressing her overflowing love and loyalty.

"Now for your last order today. Don't faint because it's troublesome to carry you."

With that, Lily yanked out the tail embedded in Mizuki all at once.

"Kyiiiiiii!!!"

Mizuki felt the greatest pleasure of the day, climaxing intensely and squirting.

She nearly lost consciousness from the overwhelming pleasure but desperately held on to follow her master's command.

"You came spectacularly... Yes, you're being conscious. Good girl."

"Ah...♡ Lily-sama...♡ I love you...♡"

Those words of praise were the best reward for Mizuki at that moment.

Lily looked down at her dog slave, convulsing with happiness, with a broad smile on her face.
