Rin asahi - adik tiriku dientot habis-habisan selama 3 hari -3

At first I was worried that I would not be able to get along with my stepbrother, but now we get along so well that we are more than stepbrother and sister! Usually I do naughty things with stepbrother without my parents' eyes, but when my parents have to leave the house for 3 days for a legal matter....I am looking forward to those three days alone with stepbrother!
