She(20F) is my(18) mother’s side cousin, we were great friends since childhood. Now she has grown up and has changed. But still we are great friends. We have a lot of fun together. But 2 weeks ago, she asked me a favour, she new my parents were going out for 1 day, so she asked wanted to bring her current Boyfriend in my house, since we are very close cousins I gave her the permission.
Her boyfriend came at the evening brought some flowers for her. I thought it would just for a meet up. But it wasn’t that, she asked me to give them my room to my room, I also did that, but this time she said to close the door and asked me to sit outside the room. I didn’t lock the door. Yeap, the ended up having a hard sex. During there time, I did sneak few times, I was very interested since I’m a virgin. I saw them having it in different positions, my cousin sister was completely naked. The were having hard sex, she was moaning really loud. I couldn’t resist myself from jerking outside the door. She was looking so hot, I wish I could fuck her! After one hour they came out, she was very exhausted, she kissed her boyfriend he left from my house. After few hours my cousin sister also left the house and asked me to keep it a secret, since I know a lot of her secrets.
