Sneak

"So, this… this… Do you understand?"

"Hmmm… okay…"

As of now, the Nakano sisters are studying with Ao.

One by one, they asked questions to him until they get it.

They are very focused that they forgot the time right now.

"EH?!! it's already 6!"

"What?"

"Yeah, It's six."

The first one who notices the time is Yotsuba, next to Itsuki, and while looking at her phone, Ichika double check on what she heard.

Since it was already evening, they decided to stop for today.

Although tomorrow is the last day before the exam, they are relaxed.

The reason is Ao said that they could get a passing score at this moment.

At first, Itsuki and Nino are skeptical about that but since the other three are blindly believe his words, they decided to accept his words.

Still, the two of them thought to do some extra study later before sleeping because passing their test isn't the only reason why they study.

They also wanted to be praised by someone special to them.

Anyway, after cleaning their school materials on the table, Ao immediately washes his hand and gets ready to cook their dinner.

…

Night.

Walking sneakily, Ao knocked on Yotsuba's room. She heard his knock but she doesn't know that is him.

When she opened it, she was instantly surprised but immediately got out of that state and let him enter.

"Why are you here?"

Even though her voice sounded angry, she really wasn't.

She was happy because he was next to her in his bed.

Ao held her hand.

She accepted it and they held hands.

Even though she loved the feeling that Ao had made him feel the other day, something as simple as holding hands warmed her heart and gave her more reason to feel like she couldn't escape from him.

Even so, she likes it and it will never change.

Little by little, Ao raised her hand and kissed it.

At the same time, Ao kissed her neck.

He kissed her upwards until he reached her mouth.

From his kiss, she could feel the fire in her body, starting to light up.

His tongue was inserted into her sweet lips.

Because of this, the sound of their kiss dominated this room.

She put her hand on Ao's head and he put his hand on Yotsuba's waist.

Little by little they take off each other's clothes.

After this, they rub each other's bodies.

Yotsuba rubbed his abs and chest.

She thought that a woman's body is really different from a man's.

It is hard and compact while for women it is soft and smooth.

Now, she come to learn that a weak girl like her should be thankful because Ao gave her affection.

On the other hand, Ao was rubbing his modest chest.

It's not big but it's not small.

It's only in the C cup and it looks like there's hope for it to grow in the future.

Ao also noticed this in her siblings so he wasn't surprised that she was the same.

Then suddenly the door that she thought closed, makes a clacking sound as it's open.

"Yotsuba, can I borrow your pe…n"
