The ambiguous aura warms up little by little over time......

"Erina ~ Let's get started ~~"

Chitanda Chengyu whispered in Erina's ear**, testing the girl's psychological defense line a little bit.

Eri Nami's pretty face was full of shyness and confusion, and she twisted her body a little uneasily, but she still nodded and opened her small mouth slightly, revealing an obedient little tongue and a neat jade tooth......

Probably、Maybe、It seems、I should be ready to let my childhood friend enter completely.。

Chitanda pursed her lips and carefully peeked into the new world in the girl's mouth through the reflection of the mirror, and there was really a pink and sweet feeling.

The surface of the inner wall of the oral cavity is a mucous membrane similar to the surface of the inner wall of the mouth, and a large number of free nerve endings are distributed, which is very sensitive to cold, heat, light touch, and pain......

Sensitive, is the key word.

Of course...... Erina has much more to face than that.

Because she kept her mouth open, the girl gradually realized that a large amount of saliva secreted from her mouth had accumulated more and more.

Especially with the toothbrush in Chitanda Chengyu's hand slowly approaching, he noticed the feeling that he didn't usually pay attention to brushing his teeth at all......

"Ah~~"

The strangeness of not being in her control made Erina flustered, but the toothbrush had already unambiguously touched the front teeth closest to her lips......

With a simple rubbing, the snow-white toothpaste, which was originally attached to the bristles, is slightly squeezed, and almost instantaneously breaks down into a large amount of white viscous liquid between the bristles and the teeth...... There's a strange sense of obscenity.

"Well, don't ......", Erina twisted her shoulder blades, which were not wide, her voice was slurred, and the whole person subconsciously leaned back.

If it weren't for Chitanda's slightly taller height, plus Erina's legs and legs, her upturned ass would have almost gone straight into the short skirt and panties.

Chitanda was also stimulated a little, and it aroused his impure desire, and a hand that should have been free was also attached to Erina's smooth thigh.

I have to say that a girl with a cold temperament like Yukino under the snow is best on the front, while a goblin with an angel face and a devil body like Erina is more suitable for holding from behind.

(It has nothing to do with big breasts and small breasts.) ）

Settled down, Chitanda grabbed the toothbrush and continued to brush Erina's white teeth in the left and right directions, the slender bristles swept over the bits and pieces of the front half of Erina's mouth again and again, and even intentionally touched the mucous membranes and gums outside the teeth.

"Ah...... Ah......h

Erina moaned softly to the rhythm of her toothbrush, probably because of the white toothpaste foam in her mouth, and there was a crispy softness in her voice.

It has a wonderful feeling of "it's better to call a bed than to call a bed".

Chitanda Chengyu's strength is not heavy, and it is not much different from ordinary brushing, but Erina, who is flushed, still closes her eyes in shyness and helplessness.

"Erina, I'm going to go a little deeper......"

"Hmm......"

Despite the advance notice, Erina is more likely to respond subconsciously.

As the toothbrush protrudes from the side and begins to clean the back molars on both cheeks, Erina feels weak, powerless and embarrassed as the toothbrush penetrates deeper into her mouth......

After more than ten minutes of "love", Erina finally couldn't help but let out a whimper like a swan being hit by an arrow, her eyes were red, and she looked like she was about to cry.

This sudden shocking change brought Chitanda Chengyu back to his senses, only to see Erina trembling all over, it turned out that she had inadvertently noticed her dissatisfaction in the mirror, and her delicate and touching appearance, and she covered her face with a "ah" and hid.

"Don't move...... It's going to hurt you. ”

Most of the toothbrush was still in Erina's small mouth, and Chitanda Narita hurriedly let go of the handle of the toothbrush and looked at Erina with some concern.

"Well, let's drink some water first."

"Hmm...... Whew......"

Temporarily cleaned up the mouth with water, Chitanda Chengyu patted her back with help, and Erina's complexion softened slightly.

A pure girl who has never been a person.,The second time she flirted with her childhood sweetheart, she encountered such a cruel training.,I think a little sensitive body will definitely be unforgettable for a lifetime.。

Senantida Chengyu touched Erina's head, a little guilty, "I'm sorry...... Are you okay? Since Erina doesn't like it, forget it......"

Erinajiao's crying voice was weak, panting for heat, and it was rare that even the roots of her ears were a little red, "Okay...... What a shame...... Just like a little kid......"

"Where, Erina is cute...... If I could, I wish this scene would never be seen by others......"

"Stupid, I don't want to be seen!" Erina glared at Chitanda angrily, bowed her head slightly and whispered, "You must be laughing at me in your heart......"

The two stood separately, and Chitanda Chengyu stroked Erina's scattered hair, showing a helpless smile, It's a bit hard to coax this time to play too much, so let's change the topic.

"How could it be...... This is a benefit that Erina has given me...... Saying...... Isn't Erina feeling comfortable at all? ”

Erina's face flushed and half faded, and she hesitated very tangledly, puffing like a bride who had just been in a cave room, and she didn't know how much torture she had in her heart. However, she still nodded shyly and timidly, and whispered, "Uh...... Actually, there is still a little bit ......"

"It's just a little bit......

Sentanda Chengyu was a little disappointed, but he didn't give up and whispered in Erina's ear, "So, is there any wetness down there?" ”

Erina's face flushed, her pure white cheeks were about to be scalded into red apples today, and it was not good to scold anyone.

"Change...... Perverted! Just...... It won't get wet! ”

"Really?"

Chitanda Chengyu was a little unconvinced, he kept hugging Erina, and he could feel that the girl's state just now was definitely not so indifferent under the front and back attacks.

The hot feeling was much stronger than when kissing......

"When...... Of course it's true! It's just brushing your teeth...... How could it be...... That's it! ”

"I don't believe it...... Unless I touch ......"

"Huh......?"

Erina's eyes widened, and she really looked cute.

"How...... What's wrong? ”

Qianantitian Chengyu was a little weak-hearted, and accidentally said the thoughts buried in his heart, so he shouldn't be killed.

"No...... Chitanda Chengyu, what did you just say you wanted to touch? ”

"Uh, it's scary to suddenly say your full name."

"Chitanda, you...... Do you think Erina is a lewd girl? ”

In the last sentence, Chitanda saw Erina's real crying voice for the first time.
