Bokutachi wa Benkyou ga Dekinai S2 - Episode 6 - Mafuyu Splashes

Mafuyu was ready for a nice, hot bath after work. That water temperature was not what she expected.

Mafuyu wanted a hot bath, but she didn't know her apartment building's water furnace was undergoing maintenance. She had to go someplace else for hot water, so of course she ran into Nariyuki, his little siblings, and Asumi.

Asumi helped Mafuyu enjoy the sauna the correct way — by dunking in cold water. Mafuyu had just been traumatized by cold water, so she was reluctant, but she got used to the nice contrast in temperatures.

Hazuki, Nariyuki's litter sister, started a running gag about Mafuyu being so beautiful, she had to marry into their family. It's kid logic, so don't overthink it. Obviously, the usual accidents at a public bathhouse have to happen, and Hazuki made it so Nariyuki would have to take responsibility for Mafuyu for no longer being able to marry.

In the second half, Rizu and Fumino had an appointment to practice a college admission interview, but Mafuyu had to substitute for the nice math teacher who called in sick. Nariyuki got roped into a practice session too. In order to mitigate his nervousness, he decided to imagine Mafuyu in less scary clothes like the track suit she wears at home.

But then he showed how much of horn dog he really is by imagining her in all the sexy outfits we've seen so far. And a china dress we've never seen before! I don't believe the nun outfit was supposed to be sexy, but I'm sure it will happen at one point.
