You need to have affection to 80% (100% to be sure) with the sisters, have sex with one of 'em while the other sister is in a room next to where you are and make some noice so she can discover you (when you are about to be discovered a "bomb" will appear on top of a girl's image on the top right), but don't let the parents discover you.how to have threesome
For the 4some are almost the same steps, but this time you need to be having a 3some with the sisters then everything is like I told you above. (You let Miyuki discover you)
(PS: 3some has it's own ending so I may suggest to get the ending first and then unlock 4some next).
