Have you thought about showing Naruto having sex regularly with his women by way of fade outs or the like as it seems right now they only seem to have sex when you write the scenes for it. You could have him getting out of a bed and turning to look at one of the women and remembering about the night before and not have to do an entire chapter about the event.
Love the chapters with the sex scenes.

I would do this, truly I would, but Naruto is already overpowered as he is and we're not even to the time-skip yet. Was this done on purpose? A little but even still. Because I would have to count those girls towards the game, I can't do this.
