What do you do when you live together with gorgeous twin sisters who are intent on seducing you? This is the daily dilemma that faces Keita Suminoe, and politely declining their offers doesn’t seem to be helping him! Despite his school friends' jealous quips, and parents who think everything is fine as the siblings are not blood-related, this makes no difference to the brow-beaten boy. Unfortunately for Keita, school entrance exams are just around the corner, and scantily-clad girls sneaking into his bedroom at night is starting to affect his chances of graduation. Can he focus his mind in time, or will breasts, panties and milky-white thighs prove to be too much of a distraction?
Yoru Made Matenai is like a twinless and less explicit shoujo cousin of Kiss x Sis. Rather than writing the "if you liked one" formula, I can say that it is very unlikely that you are going to like one of those if you didn't like the other.
