It's as good an opportunity as any, so I will recommend Sisterly Bliss ~Don't Let Mom Find Out~
It just got a Steam release after all these years (the All ages version of course), so might as well.
Sisterly Bliss - Don't Let Mom Find Out - (Tsui Yuri ~Okaa-san ni wa Naisho da yo~)

Synopsis: "Ichika and Futaba are so close it even surprises their friends and family at times. Ichika, the diligent, stubborn older twin, and Futaba, the childish, sociable younger twin, are an inseparable pair.
But there's more to their love for each other than first meets the eye.
Growing up, the two did everything together. No matter where they went, the twins were never apart. And even now that they've grown up, their personalities diverging and leading them to different hobbies, they're still as close as can be. For Ichika, the responsible big sister, looking out for childish, spoiled Futaba has become an everyday occurance, both at home and at school.
But one day, worried that the twins are growing too close, their mother chastises them, explaining that there's a difference between being supportive of each other and being codependent. Regardless of how close they are, she says, they can't stay together forever. With that admonition, the twins' relationship begins to change.
Lurking beneath Ichika's wish to see Futaba happy is a different feeling, one that torments her. A desire that cannot be fulfilled. And as their relationship changes, Futaba grows restless, seeing her wish to always be by Ichika's side drifting further and further away.
What awaits these twins, who harbor feelings stronger than mere sisterly love? What form will their relationship take, and what conclusion will their story reach?"
Duration? 6-8 hours
Gameplay? It's a pure visual novel with a choice system that leads to three different routes. The common route and one for each of the twins. What's unique is that all three routes revolve around the same pairing, Ichika and Futaba. It makes more sense once you reach those parts. If you want the purest and most fulfilling experience, follow the common route.
The CGs are high quality and the scenarios go in vastly different directions despite so few meaningful choices. The sprites are cute, but static and the voice acting adds a lot to the experience. Overall this is a very polished eroge with a lot of heart.


Yuri? Obviously. The incestuous kind at that. If you are averse to twin sisters falling in love, this story is not for you. But many may say twincest is the purest form of yuri haha
Version? There is a Mangagamer release and a new Steam release. The versions are vritually identical, except the Steam version is of course devoid of sexual content. Speaking of which...
Sexual content? It's an eroge with plenty of sexual content. I could not honestly recommend the all ages version as half the game would be cut out. If you don't want any porn, this game is also not for you.
For the Steam version I recommend getting the free 18+ patch from Mangagamer!

Sisterly Bliss is a popular classic yuri VN. The subject matter is not for everyone and the two alternate routes can go very wild and shocking, especially if you played the common route first, but in my opinion it is worth experiencing all this VN has to offer. Getting yuri eroge of this quality without any bells or whistles attached is incredibly rare, so Sisterly Bliss deserves to be acknowledged for being a standout in its niche!
