When you said you're not a dancer but you can't stop yourself from dancing when you hear a song.

koikatu 

Awesome hentai game that allows you to create characters with high detail and precision. Want to make your crush? Well with enough observations of her measurements you probably can! It'll be a little odd but only you know about it right?

This Koikatu game is amazing! I can remake myself and anyone else that I want in a 3D anime artstyle!(and fuck them)
