It's another hentai that got a family-friendly TV broadcast version. Obviously, I watched the "complete edition". It's lively and I like the cast, but its chosen kink can make it slightly hard to watch.
Souta Tsukishima's elderly father runs a sentou (public bathhouse) and works as its back-washer. (I'm not convinced that this exists outside porn and prostitution.) One day, though, dad hurts his back and Souta has to step in! In other words, he's got to scrub his customer's backs.
Souta doesn't really know what to do, so he brings a girl (Yuzuki) to orgasm by fondling her boobs and groin. In front of everyone else in the girls' changing room, while they're sitting next to him. No one turns a hair. Furthermore, theoretically, everyone in the room knows him. (They're the girls' volleyball team at his school and he's on the boys' team on the next court.) However, he's disguised himself by putting a towel on his head... and this works, even though Yuzuki and he are best enemies who are continually fighting. Oh, and she's always secretly fancied him, although she'll take eight episodes to admit that even after they've repeatedly had sex. (She's a bit of a tsundere.)
It's the porn equivalent of Clark Kent removing his glasses to become Superman. I enjoyed ep.1, but struggled with ep.2 and only didn't ditch the series because Souta's disguise gets exposed.
We then discover that this was only one expression of the show's kink. This is a show about dangerous sex where our heroes could get found or exposed at any moment. In ep.3, Souta and Yuzuki do it in the girls' shower room at school, when anyone might come in at any moment. (I suppose it's progress that there's no one else in the room this time, but the cliffhanger has the voices of the volleyball club heading this way.) They duck into a cubicle with a curtain. Yuzuki says hello to her friends, but Souta continues where they'd left off and Yuzuki responds at something like the top of her voice.
"Are you okay? What's all that noise?" Amazingly, Yuzuki's panted one-word response convinces her friend.
Ep.5 has them doing it in Yuzuki's bedroom, with her sister and classmate standing right outside the door and offering each other a drink. (In fairness, I think the sister realises. She turns up the TV volume.) Then, to my horror, ep.6 resurrected the back-washer schtick and the towel "disguise".
I'm tempted to suggest watching the censored version, because the sex scenes often have the secondary agenda of torturing you, as described above. You'll be missing lots of nudity, though. Bathhouses can have plenty of customers. (There's also a threesome in ep.6.) However, the bedroom farce angle is well done and the cast are likeable. There's also Mei Sasakura (mischievous matchmaker and club president) and the straight-laced Hidemoto Takasugi (the show's equivalent of a bedroom farce's vicar).
I didn't believe in the back-washing scenes, but I believed in the characterisation. (There are some nice reflections in ep.8 on what Yuzuki's always thought about Souta.) This is a good-natured, witty hentai with nothing nasty, mean-spirited or rapey. Souta's a nice lad and can be funny. The art's attractive and the animation's fine. It's a surprisingly good show... but it'll put you through a mild wringer.
