First of all you don't actually have to be the fan of "Final Fanatsy X" videogame to enjoy this hentai parody since it has pretty simple idea in it's basis - you go on a date with beautiful girl named Yuna and pretty soon you will fuck her real good and gentle or real hard and rough. To be honest this will be pretty much the only choice that you are supposed to do in this game so probably you will want to play this game at least twice to enjoy both options. During all other time you will be enjoying nicely drawn and rendered CG images of having sex wth Yuna from many different angles. In addition to this pretty classic visual novel scheme there will be some sound effects added during the sex scenes so keep that in mind once you will start playing.
