I am writing this down because I feel I should do it. The whole thing was a mistake, how could I agree doing something so... wonderful together with Nyu? She's beautiful, that's not the problem. What if... No, stop thinking about it! She's not even... human.

In any case, it started like a total normal day: I and Yuka had decided to clean the whole house and Nyu helped as best as she could. She observed me and Yuka and did as we did and became very happy when she noticed that what she did gave results, but also when we praised her for doing such a good job.

What I'm going to tell you started when we were cleaning the hall. I still do not know how everything really started, but what I know for sure is that Yuka told me she would take a turn to the store to purchase things that were missing.

"Okay, see you soon", I said, waving when she disappeared through the door.

Nyu also waved and smiled as usual. I never think it's been a single day without her smiling. Another thing I have noticed with Nyu is that she really likes to clean and help. It's fun that she is always so helpful, but sometimes she gets a bit too helpful.

Oh, now I'm getting away from the subject. In any case... After damming, vacuuming and standing on all four with a cleaning sponge while cleaning the floor, I decided to switch to the mop instead when my knees started to ache. Nyu, on the other hand, scrubbed the floor with her cleaning sponge, standing on all four. When I scrubbed as best, I felt the end of the mop encountering something soft while Nyu gave a little whimper.

I turned around to see what was going on, and that's when I could see Nyu hold her left breast. She looked up at me with a little surprised expression on her face. She walked closer to me and took my hand as she, to my great surprise, put over the breast she just had kept her hand over.

I was so surprised that I dropped the mop that with a clang fell down to the floor. Nyu shrugged at the sound, which resulted in my hand moving over her breast. Something that I think was a moan, escaped her and her cheeks were dyed to a deep shade of pink the moment she blushed.

"Nyu, sorry!" I managed to get out and was about to take my hand away, but Nyu kept it for some reason.

Slowly she pressed herself closer to me, which resulted in both of us descending down to the floor. Nyu began to move up and down along my hand and moaned more. I think it was then that I began to understand what Nyu did.

"Do you want me to stroke it?" I heard myself asking.

As soon as I started touching her breast, Nyu blushed even more, and this time she had gone from pink to red cheeks. It looked as if her cheeks were burning, but she made no effort to make me stop what I was doing. Instead, she put her hands around my cheeks and pressed her lips against mine. She started kissing me slowly and gently while closing her eyes.

I still do not yet know today why I did it, but I kissed her back and stroked her breast at the same time. Pretty soon, the kiss became hot and we started to make out. I was pretty sure that when we had come this far, it would only go on to the next step. Strangely enough, I did not feel nervous, though Nyu was my first and only girl I have been sleeping with.

My thoughts were interrupted by Nyu leaning even closer to me and that we both fell back into the next room, ironically, Nyu's bedroom. I quickly closed the door behind me and turned around. The sight that met me is probably one of the things that will always be set in my mind.

Nyu lay on her back in the middle of the room. Her skirt had slid up along her legs so I got a glimpse of her panties. The shirt she carried had also slid up; her stomach looked like a white little crescent with a small black dot in the middle where her navel was located.

Without understanding what I did, I was probably enchanted by Nyu's beauty, I took off my shirt and threw it down on the floor next to me. I bent down to Nyu and caught her lips in a new, deep and hot kiss. My hands started exploring Nyu's belly and then walking up against her breasts.

Nyu whimpered a little when my hands lay around her round, soft breasts. Soon she could not help interfering with our kisses. I could feel how she started taking off her shirt so I helped her.

She was even more beautiful than I had imagined. Her skin seemed to blink and just waiting for me to touch it. I could not resist it, and that was what became my fall. That was the reason I'm sitting here writing this down. That was why I left Yuka and everything else behind me to be with Nyu forever...

Rather soon, all our clothes had been undressed from our bodies and we looked at each other without saying anything. I think we both felt that no words had to be pronounced since the glances we gave each other already said all what we needed to know.

I'm not so sure if Nyu really understood what would come there and then, when she looked so deep in my eyes, she was completely naked in front of me with the lust shining from both her body and gaze. The only thing I know for sure is that she was so eager to "get started" that I took it as a sign that she was ready and knew what we were able to do.

Nyu and I sat on our knees opposite each other, deeply stirring in each other's eyes. For some strange reason that I can not explain, I felt completely calm. I took Nyu's hand in mine and smiled a bit. Nyu also smiled, but it was not her usual smile, this was a playful smile that I have never seen on her before. She always had such an innocent appearance, so it was a little shock to see her show a different feeling for a change.

Objectively and firmly she sat in my arms. She did not straddle me directly, even though I saw on her that, that was what she really wanted. Instead, she let our sex stroke against each other, which made us both feel comfortable and give us a faint gesture of pleasure. It was as though she was testing me to see if I was thinking about getting out at the last moment, but when she saw my reaction to what she did, it was as if she had made a decision she had already done before but had been unsure to dare to pursue.

As our sex stroked against each other, she watched me all the time and what I saw in them was not Nyu's eyes. It was as if there was another side of Nyu who now woke up and looked at me. When she straddled me and let me sink into her most holy, she began to move up and down while letting her arms around me in a tight embrace. I in my turn laid my own arms around her and looked her even deeper in her eyes. It was as though time stood still, as if we were the only living people left on earth...

"Nyu..." I whispered, but she silenced me by putting her finger on my lips.

When I write down this, I just want to add that I still do not know if I just imagined it or if Nyu really talked to me, but as soon as her finger touched my lips I heard a voice inside my head. It did not come from Nyu's lips since she did not move them, yet I knew it was Nyu's voice I heard. It said:

"Kohta, trust me."

Soon the pace rose a little and both I and Nyu moaned loudly. Her body seemed to melt into mine, as though we were a single person, an individual. Our lips met and seemed to eat each other, or at least it felt like that. We simply could not get enough of each other.

Her body was supported against me and our sex was reconnected over and over again. For each time it just got better and better. For each new time it only became more and more wonderful. After a while that certainly lasted more than a few minutes, but felt like eternity, it was over. Both me and Nyu screamed together when we reached our climax.

I held her in my arms and just enjoyed the magical moments we had spent together until we were interrupted by the front door that opened and Yuka's voice that shouted at us.

"Nyu and Kohta, I'm back!"

"Quickly, we have to put on the clothes before Yuka finds us like this!" I threw Nyu's clothes on her while I hurried to take on my own before I opened the door ajar and sneaked out, but not before I had made sure that Nyu really was taking on her clothes.

It would be really great if she came out into the hall completely and utterly naked... Yuka would understand that something had happened immediately before I found a credible excuse, I thought before I got to the hall where Yuka stood with some food bags in her hands.

"Hi, Yuka! Did you find everything that needed to be bought?" I wondered before giving Yuka a hug, all to maintain the facade that everything was as it should.

"Well, no problem. Where do you have Nyu then? She always comes and says hi, as well." Yuka looked around.

"I think she's still cleaning. She has really done a good job. It seems she likes to help."

I walked before Yuka back towards that part of the hall where I and Nyu had cleaned before Yuka went to the store. To my great joy and relief, Nyu ironically stood and scrubbed the floor with the mop that started everything.

"There you are, Nyu! How nice you and Kohta have done. You are a good girl!" Yuka smiled and gave Nyu a hug.

Nyu just said "nyu", as she always did, since that was the only word she seemed to be able to say. When she hugged Yuka back, she turned her head towards me and smiled a smile that was only directed at me and that only I understood. From that moment on, I realized that what had happened between me and Nyu would stay between us, and only us two.

What worries me most, and most of all, and why I write down this is that Nyu has started to act strangely in recent days. We have had more of these "special days" since that first time just over two months ago.

I think, or have a pretty big feeling, in any case, that Nyu is... pregnant.

I think Nyu is expecting my child.
