I just watched MDVR-394 and goddamn that is definitely the best VR 3P since the previous year's KAVR-402. This is one legendary pairing. Its one of those implausible scenarios we all wish would happen to us but is of course just wishful thinking.
Simple plot. You have returned to your hometown to find your childhood friends who you regarded as your "little sisters" and you their "big brother" all grown up, and totally having a crush on you so they start competing for your attention. Both of them call you "nii-chan" cos of your shared childhood but they're not really your sisters so no wincest here if that bothers you. It starts off as mildly competitive at first, as in whoever isnt taking her turn will sulk initially, but it does eventually shift tone to be more cooperative. Just don't expect any lesbian stuff as much as we might want it. These girls are infatuated with you, not with each other, so it'll be totally off-theme.
Totally worth it to have Kira Kira finally return to VR. She's a live wire and is totally fantastic at this. Fixed her teeth too and is just too pretty for porn in this one. Its also good to finally see Touno Karin without the awful titan camera that she always seemed to end up with. She surprisingly has one helluva potty mouth and spends much of the VR being obsessesed with your cock. That's not a bad thing and is actually quite fun to listen to in VR if you understand enough Japanese. Kira Kira acts a little more innocent but both of them don't ever stop declaring that they love you (nii-chan daisuki) although sometimes when its Karin saying it she might be referring to your cock instead (nii-chan no chinchin daisuki).
So, who do you pick? The purer girl who loves you or the horny girl who loves you and your cock? Decisions... decisions...
Actually, I am definitely picking Kira Kira but that's only cos of a personal bias. Karin doesn't exactly make the choice easy though. She's that good. Despite my bias towards Kira, I don't actually mind when Karin takes her turn. I don't always feel the same for all 3Ps where I might favor one girl more than the other.

Who doesn't wish they had two bra-less cuties wrestling with each other over who loves you more?

"Ladies! There's no need to fight over me."
"You stay out of this and just watch!"

The sumo wrestling turned out to be a draw, so they start butt wrestling instead.
No one even got naked yet and its already a VR of the year candidate for me.
Eh, just go watch this already. I don't feel like I need to say anymore. This VR is definitely worth your time unless you just really hate 3Ps for some reason.
2026 wish list filed: Kira Kira back in VR, and in a really fun title too.
