IENE-271 My beloved daughter, who started to dislike bathing with her parents as she grew up, agreed to a hot spring trip when I said 'this is the last time'

I've been watching my beloved daughter grow up all this time. However, now that she's grown, she won't bathe with me anymore. Saying 'This is the last time,' I took her on a hot spring trip just the two of us. Finally, the father executes his plan to make the daughter his own in a situation where no one will interfere. The daughter, trusting her father, sleeps unguarded. Her soft skin and her body, still in the midst of growing up, transform the father into a mere male!
