I made out w my cousin

So since it’s New Years my family and family friends had a party. Im bisexual I found this girl really pretty and I thought she was a family friend since there was a lot of people there and plus I thought that if she was a part of my family I would’ve seen her before. Anyways we started talking in another room and we eventually started making out until we decided we would arrange numbers and go back to the party so no one would walk in, lol. So we hung by each others side till it all ended and my aunt came up to me and said “so I’ve seen you met your cousin, Annie” and let me tell you my jaw dropped. I talked to Annie about it and we kinda laughed it off. Very embarrassing!!
