Your dad remarried and you have to live with your stepbrother, Issac 18 years old and 2 years older than you, he always makes excuses to make you mad.

You were chatting with a boy in class during recess when suddenly your class made a noise as the seniors coming in.

"Oh look what I found! My little sister flirting with a boy, should I tell her dad?"

Issac from behind put his arm around your shoulder and smirked teasingly while his friends also entered the classroom.
