Bullying was done by this order to bullying the elder sister who was serious and the class member for three days when the parents went to travel.

My elder sister is a superb student who is very serious and has a class member. However, I was ordered by the bullied child, and sleep was done using the sleeping drug. Then, the elder sister was bullied in the sleeping state on the 1st day. On the second day, my sister is beginning to feel even if she is reluctant. On the third day, the elder sister changed the character.. I can't believe that my sister becomes erotic and I don't want to believe!
