Those who feel this needs vanilla tag say aye!

Well they're a very fitting couple. He's a lucky guy and I'm glad he realises and appreciates it.
I mean, she can be both an elder sister, younger sister, and lover? Such a perfect woman, he should marry her already. And he does propose by that end! Awesome, you go man. Much respect to our protagonist, definitely a great ending. Next step would be getting her pregnant and living a happy family life.
Also it's quite evident they love each other, why do we not have a Vanilla tag?
"When a man's dick gets this hard it's because he wants to make a baby with the one he loves"? I like this sentiment. Very nice.

Brady Bunch, hentai style.

It's the type of foreplay that can keeps the relationship ongoing.

This was so flippin' good! Usually, stories like this are too unbelievable. But this was awesome!

Interesting story, but that is some crazy big genitals!

Isnt this vanilla at its prime?

We need a sequel to this.

I need to start doing Dick push-ups so I can hold a girl up with my penis also.

This is a rather odd relationship but I love it!!

I am in love with this satsuki imonet is hands down my favorite artist

Add vanilla tag plz and this is great

two big ol' sweeties banging like no trmw.

From Incest (or perhaps that should be 'Wincest') role-play to lovey-dovey baby-making sex.

APPROVED!

A big family of sequels is needed!

This is kinda creepy though.

Holy shit, wife of the year! This is vanilla as hell.

Oh yeah, they are indeed made for each other!
