Complex

Wife: Today I†˜m making your favorite!
Sister: But I had Hiro–kun already...
Wife: What?
Sister: What?

as long as they're all (un)happy

Dose this count as NTR? And did he force it on her?

Someone just drwe my dreams.

How have i missed this artists? Now following.

Loving the tags on this one~♡ Would love a sequel where the sister joins in on the fun too though!

"I'm married now and had made up my mind to only love kazuha" -> "" It's no use, I can't hold back".
I suppose tis only a natural reaction for a Hentai Protagonist.
Ah, and he felt a pang of guilt when his wife mentioned she trusts him, and asks to stop...But what Kana said also rings true. "You've been betraying her all this time, and now you wan't to stop"? I suppose he should have done so earlier if he felt guilty, or just admit what happened between them. After all, that was before their marriage. But it turns out that of course she also loved him all this time, but then he went and married her sister instead so this is the only way she can have him to some extent.
"Even if it's only until my sister finds out"? Well, chances are that if that happened, the spot of wife might open up, eh? Either that or a 3P, who knows when it comes to Hentai.

Wow. In my lifetime I've seen quite a few instances that showed that somebody thought the other person was a moron, but the younger sister boldly takes that to new heights. "I'm going to screw your boyfriend right in front of you, and you're too stupid to realize it." Unfortunately, it looks like the younger sister is right. In Hentaiverse, chicks don't have that sixth-sense real life gals do when her guy is cheating, esp when it's done as frequently as in this story.

The sequel should be the Mc fucking both.

Kinda like Hajimete no Hitozuma. Only instead of the Dad fooling around with his son’s fiance (whom he had a past relationship with), it’s the sister foolin’ around with her elder sister’s husband (whom she had a past relationship with.

This girl is too smart for the guy she's clearly playing him into getting her pregnant to destroy her sister's relationship.

Let us hope that Hiro either manages to keep his (a-hem) 'extracurricular activities' concealed from Kazuha, OR he somehow manages to (a-hem, again) raise some sort of "consensual threesome" flag ... otherwise, things have the potential to get really ugly (BRR).

It's my hope that Kazuha know what's going on (because you know you can never fool the onee-chans) but is kinda ok with it since she knows how Kana is and she knows Hiro would never do anything to hurt Kana.  Kazuha then reveals to Hiro and Kana she knew since the first time they did it and tells Kana she's welcome to stay with them since they both love Hiro and Hiro loves them.    :) 

Kana-chan is such a sexy little imp (page 6 ❤).     Peak inseki.
