I (22F) fucked my cousin (18M) [FM]

We last met 6 years ago, on our grandfather’s cremation. He was a very innocent child, carefree from real life responsibilities and had flawed knowledge about intercourse. We became great friends. He had a cocky way to complete me and taunt at the same time. “You are kind of fat, and I find it cute. We would be a great couple” he said. “Indeed, I would love to be your faithful wife for life” . He came back here few months back. Totally jacked up he was, no more the kid I knew. As expected he started flirting with me, and I flirted back. We were talking and in no time we reached the topic of kinks. Surprisingly, he was into cuddles too. And of course he joked about it, but there was a sense of seriousness in his eyes, as if he literally meant we are a great couple.
