"That Sheena, why the heck did you drop your book out of all things?" I whispered to myself as I look at the book at my left hand.

Right now, I am heading towards Sheena's classroom because I accidentally saw a book lying in the middle of the road earlier which happens to be her property. Because I was already late for the morning class, I decided to give it back to her in the lunch break.

When I arrived at her classroom, there is no one there.

"So her last period for the morning class is PE."

Suddenly, I heard voices coming from outside so I immediately hid myself inside a locker in the back of the room.

Why the heck did I hide in the first place? Am I really that scared to a crowd?

After a while, the girl students that belong in this section gathered inside the room.

"That's tiring."

"Really."

"Then, let's change."

"Make sure that you close all the curtains."

What the...this situation...

Suddenly, all of them including Sheena removed their PE uniform.

Th-they are changing clothes! Crap! If they found me, I will be killed!

Suddenly, the cross around my neck emitted a green light.

"Green? What will happen to me?

Anyway, thank God that I am the only one who can see this light."

But now that I noticed it...this section...is quite the powerhouse. That…girl…and that girl…and that girl…woah! They all have nice figure! Wait! Why the heck am I ogling at a time like this?

"Anna, can you get the broom in the locker? Someone messed with the chalk dust here in front," a girl asked who just finished changing into her uniform.

"Sure," the girl named Anna replied and started heading to my hiding place.

Crap! I'm busted! I shouldn't have come here after all!

Then, the girl opened the locker and got surprised.

I then closed my eyes and covered my face.

I'm dead...

"It's not here," Anna said with a puzzled face as she looks around inside the locker.

Wait...

"I think the other section borrowed it," one girl said.

"Really?" Anna reacted and closed the locker.

Don't tell me that...the green light makes me invisible???

"But for now...I'm saved..." I whispered with a sigh of relief.

Because no one left the room the whole afternoon, I hid inside the locker until everyone went home. After making sure that no one will come back to the room anymore (because it is already past six pm), I decided to go out of the locker.

"It is still emitting a green light. A...it disappeared."

Suddenly, I felt an indescribable feeling that made me lose my reasoning.

"Hehehe..." I laughed in an evil manner.

When I arrived at the gate, I saw Laira waiting for me.

"Orel, where did you go? Why did you skip the afternoon class?" Laira asked with a worried face.

"Laira, we will now commence the operation 'eliminate your shyness - extra' this instant," I announced with a serious expression.

"Right now?" she asked with slight surprised look.

"Yeah. First, wear this," I said and gave her a collar with a chain.

"What is this?" she asked with a clueless face.

"You will act as a dog and crawl around the school."

Because of what I've said, she immediately got surprised.

"But..." she reacted with a very confused look.

"Isn't that embarrassing? If you overcome this, you will surely get rid of that shyness."

“...”

“What’s wrong?” I asked, still with a serious face.

"Then..." she replied obediently and wore the collar. I then took the chain and stared at her sleek legs.

"O...rel?" she whispered, not used on someone staring at her legs.

"Now, stand in all fours."

“…”

“…”

"Yes," she agreed in a resigned tone.

"Not yes. Say 'woof'. From here on out, you will end all of your sentences with -woof. Understood?"

"..."

"..."

"Woof," she replied with a very adorable look. I should have brought the kemonomimi headband in my house.

After that, we walked around the hallway like a master and his dog.

"Master, when will we stop walking-woof?" she asked in an obedient tone.

"That's probably enough. Now...to the next stage."

"!"

I then took out a Frisbee and showed it to Laira.

"We will play using this. Just catch it and bring it back to me. If you succeeded, I will give you a reward."

“In all fours again?” she asked with bright red cheeks.

“Well, since I’m kind, I will let you stand with your two legs just for this stage. Be grateful.”

She then stood up and replied,

“Thank you very much, Master.”

“Don’t forget the –woof.”

"Woof!" she replied with a really embarassed face.

“Then, let’s start!”

I then threw the frisbee away but Laira didn't manage to catch it so she just picked it up and brought it to me.

"Master, pardon me-woof," she apologized with a sad look.

"I said that I will give you a reward if you catch it but...because you didn't...its punishment time."

"!"

"I will now lick your neck," I announced, still with a serious expression.

"Eh?" she reacted with a very surprised and flustered expression.

"You are a dog, right? Your reward should be my permission to lick me but because it is a punishment, I am the one who will lick you."

"B...b...but..."she whispered, confused.

"Don't move," I said and drew my face closer to her neck. It smells surprisingly good.

"Or-Master. Don't...." she reacted while twitching.

I then licked it slowly. After a while, she placed her hands on my face to stop me.

"N-no..." she whispered with a very red face.

"I said that it is a punishment right? Deal with it."

I then continued licking her. Because of this, her shoulders started twitching more often. She also started to pant silently.

"Or...rel..."

I then stopped and said, "Let's go to the next stage."

"...Yes...*pant*...Master..."

"It looks like you are tired. Want a drink?"

"Yes...Master."

"Don't forget the -woof at the end."

"Woof."

I then took out a mineral bottle in my bag and saw that it is just around a gulp.

"A dog can't possibly drink in a bottle so I will feed this to you through my mouth."

"!"

I then put the remaining contents inside my mouth and knelt down.

"Wai--”

Just before she finished what she is about to say, I immediately kissed her and transferred the water to her mouth. After a while, she finally drank all of it.

"..."

"Not enough?"

"That's—”

“Then, it can't be helped."

To quench her remaining thirst, I plunged my lips towards hers and when she opened her mouth to catch her breath, I forced my tongue inside. Her shoulders twitched out of surprise so I immediately hugged her to prevent her escape. She then gripped my uniform tightly, trying to push me but as I move my tongue smoothly inside, her grip gradually got weaker. Before I know it, she is now trying her best to twine her tongue around mine. She is now kissing me back. Our tongues intertwined with each others, expressing our desire to continue what we’re doing. After a while, she pushed me away; making me drew back a little, just a few inches apart.

She then panted two times and said, “Let…me…rest…for a bit.”

Because the only thing in my mind right now is to taste her, I once again plunged my lips to her lips and continued. The air is now filled with faint wet sounds because of our long deep kiss.

I then drew back and panted. When I stared at her, I noticed that she is breathing heavily. Looks like I got too forceful that I didn’t let her breath since I forced my tongue inside her mouth.

"I will give you a minute to catch your breath. After that, we will continue."

“...*pant*...*pant*..."

And after a minute...

"Now, for the last stage..." I said with a grin.

I want to do this to her for quite a while now. This time, I can finally—

"Who's there?" a guard shouted.

"Crap!" I reactee with a surprised face.

"Mas--"

I then lifted her and carried her in my arms.

"Strength boost!"I shouted and the cross around my neck emitted an orange light.

"Wait!" the guard shouted while pointing his flashlight to us. He is quite far so there is still hope that he didn’t recognize us. All we’ve got to do is run!

"Strength boost - Cheetah!" I shouted and the orange light from the cross enveloped my legs. I then ran like the wind and eventually reached a high wall standing in my way.

"Hang on tight!" I shouted.

"Orel?" Laira reacted with a surprised yet nervous look.

"Strength boost - Kangaroo!"

After the orange light enveloped my shoes, I immediately jumped, over-passing the wall like it's nothing. After we landed at the other side, we immediately hid behind a tree.

"It looks like we are safe now," Laira whispered with a sigh of relief.

"Ah!" I reacted out of sudden pain in my head and I placed my hand on my forehead.

"Ore-Master, what's wrong?" Laira asked with a worried expression.

"W-what the heck are you calling me? Laira! Why...why the heck are you wearing a dog's collar?" I asked after finally regaining my consciousness.

"What do you mean? This...is your order, Master," she answered with a puzzled look.

"Wha--" I reacted with a very surprised face.

She's right. I am the one...who gave it to her earlier.

"A-anyway, I will now remove it," I said with a flustered expression and hid the collar on my bag.

“What the heck did I do?” I thought to myself as I stare at the innocent look of Laira.

That moment, I realized that lust just governed me. It’s like I am doing something against my will. The side-effect of the green light is...the inability to control your sexual desires? What's up with that side effect? It doesn't make any sense! But what a relief that we didn't reach the last stage! Anyway...what the heck is the power of the green light?

"Master...will I wear the collar again tomorrow-woof?" she asked curiously with a somewhat invisible tail on her hips, wagging.

“…”

“Master?” she called with curisioty after slightly tilting her head.

"So..." I whispered while looking down.

"So?" Laira repeated.

I then knelt down and head butted the ground.

"Ore...Master?" she reacted with a surprised face.

"I’m very sorry!!!!!!!!!" I shouted as loud as I can.

And that night ended with tears in my eyes.
