I [M] had sexual relations with my younger [F] cousin

This is a bit of a dark one. I had sex and did sexual things with my cousin. Yes I am fully aware it is incest, no where I am from it is not illegal. She is my cousin through my maternal aunt, and the eldest of all my cousins. It started in the summer last year, when we were all staying at my grandparents house in the countryside. I rarely see her as she lives in Ireland with her parents, so it was good to see her after so long. After a few days, we had grown bored of sitti g arou d and talking, and decided to play some video games. We were casually playing on my PS4 in my room when I had the urge to touch and get physically intimate with her. We had been flirtatious in the past, but nothing explicit at all, but I did have fantasies about her which I used to Jack off to.
