You can find the bonus scenes in the folder inside the computer. To unlock them, you just have to follow each girl's stories. There is a bonus scene for every heart of trust, affection and lust.

Thank you, their there now, and theyre awesome. I love the story so far. I have another question though, if its ok. 
in rina's gallery, theres six scenes, and you can unlock 4 through her direct story. Am i missing something? Also if this is a repeat question im very sorry!

At the moment, those scenes have been removed because there were too many problems, or they happened too quickly. I plan to re-add the fifth scene in the next update and completely redo the sixth scene.
