We REALLY need someone to translate this game proper. Apparently, according to some ppl on other forums I've visited, VNR is broken because of the recent Windows 10 update.
The following are things that should help you guys a bit, should you guys need some Translation.

The pic below is the "battle" menu, so to speak.
Get Inserted (?) basically means you get fucked. This is the winning way.
Reverse Sex means you fuck the other party. This is the losing way.
The Gentle and Rough options will only appear once you choose one of the two above.
Grow Dick will appear the first time around, I think.
For the mainstay ones, they're [Kiss], [Boobs], [Clit], [Handjob], and [Own Feelings(?)]
I added the question marks because I'm not sure if it's the right expression for the word in question.
