In Fact

FMCs reactions to the MCs reactions made this story pretty interesting, you don’t usually see the housewife-type lack so much compusure.

There are eight million cheaters in the naked city.

Cheating is widespread in Japan (it's practically
the national pastime), so this chapter is a realistic
depiction of a typical adulterous relationship.

Immoral sex feels even better than regular sex. ❤
That really just boils it down well why this is so hot but both of their reactions to everything, like her worried that he hates her and him saying he wants to be with an amazing married woman, really makes an explicit cheating story feel more like vanilla. I've been jumping around Sanjuurou's works and this feels very tough to beat as my favorite of theirs.

The end comment from the guy was absolute gold. Also, a more interesting cheating story than the ordinary "unsatisfied housewife goes full on asshole".

Who knew that vanilla and cheating could coexist so beautifully in this lovely erotic featureðŸ˜

Sanjuurou’s artwork is pretty impressive.

This was hot but not really for me because of the uncomfortable context. But damn, Sanjuurou's art is still godlike.

I like the art, but the story hurts.

Mao-san is a top tier onee-san both sexy and cute plus you add the alluring charm of a housewife makes for very lovely combination!

Maaaaaaan Sanjuurou really knows how to take it to the next level. The characters decided to go full-throttle even though they are fully aware that what they are doing is wrong and that's sooo hot. They didn't care how bad it was. They just wanted to each other that badly. GOTDAYUMM.

Sometimes I feel like this cheating is engraved in our genetics only varying in it's amount. All life forms ought to seek for better genetics to pass on better genes and we humans are of no exception. That also explains why sex brings us pleasure, and to some people a much better one during cheating.
btw that "Well, now I am..." in page 15 hit me hard...

At first, it seemed to be merely the formation of a physical hook-up between a (relatively) young MC and his Senpai from his part-time job. I wouldn't blame Takao for becoming smitten with Mao-senpai, who also definitely qualifies as a "Sexy Onee-san". Once the revelation comes out that Mao is actually married, the Intensity Level apparently went off the charts, as Takao seemed to desire her more. Opinions may vary as to whether he truly desires Mao, or if it's purely the thrill of engaging in infidelity that's driving him. And for reasons all her own, she seems to be a willing participant also.

In The End, Sanjuurou-sensei proves a point that said artist has delivered before and other artists have done in similar manner:

"A CHEATING SCENARIO IS NOT SUPPOSED TO BE THIS HOT!"

"DAYUM!"

Holy fucking shit. This would probably get my vote for manga of the year.

Gripping story, great art, and has a few panels that really draw you in emotionally. Kid in the konbini made me laugh, too, lol.

10/10, very literally.

Mao-san is S+, prime housewife material.
Perfect housewife booty alert on Page 5!

It's crazy how just learning one piece of information completely change the context of the story and characters motivations.
After Takao found out that Mao was married and they still wanted to continue their relationship, this chapter felt way more scandalous :)
