[Chiguchi Miri] Public Bath and Porn Book Day (COMIC LO 2022-04) [Nishimaru]

Little Yuina kills time at the public bath scrolling through porn on her phone, but free samples only leave her burning with curiosity about what a real one looks like. A chance encounter with a lone man in the washroom turns into a steamy hands-on lesson, and the bold third-grader wastes no time inviting him back for a full round—cheerfully suggesting they play pretend as father and daughter to cover their tracks. Eager, shameless, and always one step ahead of her flustered partner, Yuina turns an ordinary bath day into something neither of them will forget.
