( Yuuki's POV )
The footsteps outside my room grew louder, and when my door burst open, a cute blonde launched herself onto my bed.
Ku: Onii-chan!
Kusano, the cute little sister of the original Sekireis, she had grown into a beautiful woman, but she kept her sweet personality and continued to call her Onii-chan.
Yuuki: Ku, what are you doing here?
Ku: What kind of question is that? I'm going to spend the night with you.
Kusano was wearing the kimono she wore to the festival and her top was slipping off her shoulders.
Ku: This is the bond between Sekirei and Ashikabi.
Kusano didn't have her innocent look on her face, and I didn't need any more signs to know where things were going, but she gave me a big one when she pushed me onto the bed and gave me a deep kiss.
Her wings of light spread out and she pulled down the top of her kimono and showed me how much she had grown.
Ku: Do you see me as a woman, Yuuki?
I knew this day was coming and when Kusano called my name, I went for her giving her another kiss while I fondled her breasts, I took off my pants and put one hand under her kimono, I used my fingers to play with her pussy and when she was wet I pushed her onto her back.
Yuuki: Kusano, I'm going in.
Ku: um, I'm ready Yuuki.
I entered Kusano while she was hugging me, and when I was completely inside, she said something that started to boil my blood.
Ku: The girls told me you have a lot of energy at night, I'm ready for that.
I clenched my hand and started to move, soon I was pistoning rapidly, Kusano was letting out sweet moans, which fed my excitement, I released my first load inside her, and I kept going with another and another.
Other times I always had more than one partner, and when I pulled my cock out of Kusano I wanted to give her a break, but she turned around and tentatively shook her ass at me.
Ku: I know you haven't had enough, I'll take care of you all night.
Kusano's words removed the brakes I was trying to put on, I hit her from behind with great energy, and her moans became louder and wilder, She lasted several rounds but couldn't make it through the night.
Although the night didn't end there, Asia appeared to support her, and I enjoyed my time with my two beautiful blondes, and when we finished, they fell asleep in my arms.
/////////////R-18 end////////////
The day after the festival, I had no work planned other than the usual training, but Kuno called me and from a watchtower, we saw one of those armored trains stopped on the outskirts of the city, the stations don't survive without their walls protecting them so they must be perplexed by a place like this.
Yuuki: let's get closer, this could be an opportunity.
Kuno and I jumped into the hybrid Gears positioned on the edges of the city, these were remote-controlled, and the cabins opened automatically when we approached.
As I flew alongside the train, I spoke through the communication system.
Yuuki: [Attention, you are entering Babylon Kingdom territory, declare your intentions or continue on your way.]
Conductor: [ We made an emergency stop, we needed some repairs and some portions, but we didn't know if this station was still standing. ]
Yuuki: [ If that's all you can come in, we'll take care of you. ]
With the first visitors entering our city, I spoke with a representative of that group who was the driver of the train and we talked about what they needed, We could give them what they needed and when it was time to talk about payments I told them that we did not need money but in exchange, I asked them to arrange a meeting with the leader of their station, because of what happened on Miu's trip, that meeting would be in our city, the driver's response was that he would send the message but he didn't guarantee that they would respond but that was okay, I knew they were going to contact us again, out of curiosity or caution, something was going to force them to act.
Our visitors left the city hours later, and when I had time I went behind the castle where I had created a training camp for IS, what I was most interested in was Kuno's personal unit and we started testing with it, her unit was similar to Cecilia's with a powerful sniper rifle as its main weapon, and was equipped with many missiles.
Kuno passed the firing and flight test very well and then came the most important thing, the IS was designed to increase her power and when she released her Banshee scream her IS concerted and amplified her power, she pointed at the forest and her voice was able to knock down two dozen trees, then the girls tried out the other units we had created for them and the rest talked to me about the designs of their personal units, the IS were not compatible with the fighting styles of some of the girls so I started designing a light version for them.
After that I went to the place where Miu's group first arrived with Kuno, This was going to be our base but now it was an outpost with a pair of Hybrid Gears on standby, I was planning to create other outposts like this around the city but when I told Kuno about it she was very focused on the tablet she was carrying.
Yuuki: Did something happen?
Kuno: I'm detecting a signal from Kabanes, they're moving very fast.
Kuno showed me a map, and I saw the enemy's signal moving quickly and their destination was the station that Miu had visited a few days ago.
