I stole my sisters flowers on Valentines Day.

I (14F) and my brother (12M) were both crushed on our babysitter (17F) we asked her to Valentine's Day but she said no. So my little brother decided to get her flowers. I wanted to fuck with him and give her the same flowers. So I stole my little brothers flowers and gave them to her as my own. She loved them and thought they were cute. My brother was crushed when he found out it was me.
