Chapter 1.- The arrival

Kei Kuzanawi lived the dream of every teenager his age. At 16, he considered himself the most fortunate young man in Japan to be married to a beautiful 20-year-old woman who, apart from having a sexual and erotic body! She was from another planet!

However, not everything was happiness for the young couple, due to the sexual inexperience of both it was very difficult to reach the supreme moment of love, in other words, having sex.

Kei understood that while thinking as he arrived at the building where he lived with his beloved teacher, Tender kisses on his cheek, occasionally holding hands, on very rare occasions hugging and giving each other loving looks, was all they had done.

After remembering that, Kei gave a huge sigh, he wants to have a more intimate level with her but due to his inexperience with women he was afraid of committing nonsense that could disturb his beloved teacher.

However, his hormones and his arousal for her demanded much more than just hugs and glances of love, Kei could not help but remember with lust the sensual and erotic body of his wife.

And it was true, the woman owned sensual and divine breasts that drove him crazy just thinking about them, but what most excited him about his wife's body were the enormous buttocks that she had.

The teenager's excitement increased when he remembered the occasions when he had spied on the woman when she was bathing, in this way Kei could appreciate the sensual and erotic body of the woman, in addition he enjoyed masturbating while smelling the panties of the beautiful alien. That was enough for his penis to become erect and so, as Kei walked up the stairs, he discreetly massaged his member, futilely seeking to ease his burning.

Finally an image of him penetrating his beautiful teacher through his anal hole made his arousal to the maximum. Kei entered his apartment looking to go to the bathroom to masturbate while he would be smelling a woman's panties, it was not the solution he wanted but at the moment he could not do anything else.

The evening was about to end and to enter the night there was very little sun but still enough. Kei was surprised when he saw his beloved teacher on his back, who was leaning on the balcony of the window and admiring the beautiful sunset.

-Sensei? But I thought that she was going to arrive later due to a work meeting with teachers.

The young man thought.

But that did not matter, the woman seemed not to notice the arrival of the young man and continued to admire the landscape.

The sunset was about to end, the sun was slowly disappearing. A soft breeze of wind moved the long hair of the woman. She wore a green sleeveless top revealing her long, bended arms.

She wore a brown skirt that reached down to her ankles and was wearing black high-heeled shoes that made her bottom rise. The woman had her shoulders on the balcony, she was bent over a bit and making her rear stand up a little more and showing it fully and in all its splendor.

As said before, perhaps what most excited the teenager of the beautiful woman was her buttocks

And as Kei was approaching she noticed that sunlight hitting the thin fabric of her skirt and revealing the silhouette of her beautiful and sensual legs. Kei gulped, since as her gaze went up the thin fabric of the skirt allowed her to admire the woman's panties without any problem, the teenager sweated when he saw the silhouette of the pantie and understood that it was one that was a thong that covered only half of his buttocks.

The young man as we had said before, was already completely excited due to the sexual fantasies he had with his beautiful teacher.

Thus, unable to contain himself any longer, he decided to risk everything and slowly placed his hands on the beautiful woman's shoulders. The woman shudders in surprise at the touch, Kei immediately slides his hands down hugging the woman by her sensual waist and sticking his body to hers.

-It's me Sensei, Kei. -He said with a reassuring voice.

-I'm so sorry sensei, but I couldn't help it, OMG I ... I saw you so beautiful that ...

Kei placed her face on the woman's neck and closed her eyes.

Kei noticed that the woman stopped moving when she heard his voice. He with his eyes closed and living a wonderful dream smiled and began to kiss her softly on the neck. The woman completely paralyzed her body when she received these caresses and to the surprise of the young man she felt how she leaned her neck back facilitating the caresses he was giving her and making him very happy.

-I love you sensei.

Kei said in a soft voice as He kissed the woman's neck with her eyes still closed and living a moment that He didn't want to ever end. However Kei began to get excited again to have in his arms that sensual and appetizing body that had made his penis become completely erect.

And so, burning with pleasure, he swallowed and begged God that she was not going to reject him and without being able to contain himself, he stuck his erect member to the fleshy ass of his beloved teacher. And ignoring that woman WAS NOT HIS WIFE.

The woman, feeling the hard member of the young man in her butt, opened her eyes and her mouth very large, her body shifted a little but she did not resist and she let herself be enjoyed by Kei, a small smile formed on her sensual and beautiful crimson lips .

Kei was happy to understand that the woman had offered no resistance and with more confidence began to rub her erect member against the woman's appetizing butt.

The woman could not help but feel a sense of fear and excitement as she felt the hard object rubbing against her bottom.

-Oh gods! For a long time, I have not felt that sensation in my body.

Kei was still with his eyes closed immersed in that wonderful moment he was living and wanting it to never end and so for a long time he continued kissing her neck and rubbing his erect member against the delicious butt that excited him so much and without the woman opposing it any resistance. Keri's excitement was increasing and an idea formed in his mind and with fear He thought:

-!Oh God! Please let her let me do "it"

And then slowly he slid his right hand down the woman's broad hips and trembling with excitement placed his hand on the woman's buttocks. She opened her eyes and mouth again when she felt that hand and moved her hips a little, maybe a little uncomfortable to feel that hand on her buttock, but she never resisted.

The teenager was happy to see that the woman did not resist having that hand on her buttocks and then he whispered in her ear:

-Thank you, sensei, I love so much.

And so, with his eyes closed immersed in a world of sexual fantasies Kei is kissing the silky neck of the woman.

With his left arm he had the woman hugged by her sensual waist, then he separated his erect penis from the woman's butt and with his right hand he began to handle the fleshy and wide butt of the woman, she for her part, remained without moving her body and remaining silent.

Finally the sun began to hide and a soft breeze of wind caressed both bodies, Kei stopped fingering the woman's butt, hugged her by the waist with both arms and whispered to the woman in his ear:

-Please, go inside.

The teenager delicately pulls the woman's body into the room. Kei kept his eyes closed.

She allowed herself to be led by the young man's soft embrace, which did not detach his body from her, but, Kei's erect penis began to rub again against her buttocks.

The room at that time was already dark, only a small beam of light dimly illuminated the place.

Kei carefully forced the woman to press her body to the wall, increased the pressure of his embrace on the woman's waist, and began rubbing his erect penis on the woman's buttocks while making moans of excitement.

The beautiful woman remained silent, placing her hands on the wall and allowing the fiery teenager to enjoy her body, a shy smile formed on her lips as she thought:

-I never thought that this would happen, I never imagined that this young man was so excited with her.

It was then that she felt that the young man stopped hugging her with his right arm, a mischievous smile formed on his lips.

-Surely this boy is going to hold my buttocks again.

But what Kei did was whisper to the woman in her ear.

-Please, sensei, please...I beg you.

Puzzled the woman thought.

-What? Please, what? What do you want to do young man?

The answer comes when she feels that the young man's hand ... began to lift her skirt!

Kei trembling with excitement knew that only two things could happen; That she put up no resistance or that she got very upset and slapped him hard.

And so, trembling with excitement, he slowly began to lift the woman's skirt, she for her part swallowed at the audacity of the young man.

-!Oh Godness! And now what do I do? - She thought as she felt her legs begin to be exposed.

To be continued...

Who is the mysterious woman that Kei mistakes for his wife?
