Cousin Snuck In My Tent

So when I was 16 I went to a camping together with my uncle, aunt and their daughter (my cousin). I had a separate tent to them since the trailer they had only had place for 3 people to sleep. So I set up the tent together with my cousin. Emma was 15 at the time and she is very attractive with her long blond hair and she already developed some tits. I stared at her cleavage a bit and she caught me looking. I quickly looked away but Emma just laughed a bit. The tent was eventually set up and we all went to sleep. Suddenly I wake up in the middle of the night. My cousin had gone to my tent and woke me up. I was worried that something was wrong but she said that she owed me a peak of her tits. So she then took her top off and she had her tits fully exposed. They were so beautiful and it was my first time seeing boobs in real life. I asked if I could touch them and Emma answered with off course. They were so soft and my dick became really hard. She noticed it and wanted to see it as well a bit of tit-for-tat. So I showed them and she was a bit in awe. Emma had never seen a dick in real life so this was a first for the both of us. She wanted to touch it and began jerking it a bit. She got wet herself and asked if I could touch her as well down there. So we both were doing this for the first time and eventually I just asked if she wanted it inside her. Emma was a bit hesitant at first but she agreed. So she laid on her back and I put my dick in her. She gasped and her breathing became heavy as I slowly went in and out. After a couple of times I couldn't hold it anymore and I came in her. She was disappointed because it was over so soon. I offered to finger her so she would be more satisfied and that is what she wanted. So I fingered her a bit (well tried to because first time). So eventually was more satisfied and went back to the trailer. So next night we fucked some more and I could hold it more. We did this for the rest of the holiday for around a week. Afterwards we fucked sporadically some more.
