13 Yr Old Me

There I was, 13 years old at my older brother's house party. Had a serious crush on one of his friends for ages so when he started chatting to me I was over the moon. He said I was cute and he wanted to kiss me, I was so excited but he said not where everyone can see and took me to my room and closed the door. Pushed me up against the wall and kissed me, I was in heaven. He pulled the straps of my dress down exposing my still blossoming breasts and started playing with them and leaned in and sucked each nipple. My dress fell to the floor leaving me in just my panties, he pushed them down and put his hand between my legs and pushed a finger in me. Just then the door opened and 2 guys walked in. There I am practically naked, breasts exposed with him fingering me, thry burst out laughing. I nearly died from embarrassment.
