The best thing for her might be to let her have this. Once his dick was exposed, she stopped and looked him in the eyes. "What next him!?" she asked. He just looked at her in surprise. It was pretty shocking. "Uhh... they did explain to you how babies are really made, right?" he asked to confirm. She just rolled her eyes at him. "Of course they did! I was told about sex. We couldn't have children together if I did not know that information. I know what to do. I just want you to do it. You're the man here." she said. That put Kazuki a bit on the back foot. He had been leaning towards lying back and letting her do the work. "Oh, okay then. Let me think about it a bit then." he said after a few moments to process what she said just then. It was not like he found her unattractive. Natsuki was stunning. It also was not like he did not have fantasies of his own on what he would want to do with her. He just had to put it in action. The time had now arrived. Kazuki quickly got to work. He had her in doggystyle first before some missionary. He made sure to drain his balls inside of her. They then laid down.
