My cousin fucks me and ejaculates in my mouth

Since they were kids, these cousins have had a very close relationship and always spent time playing together. The girl has been very pretty since she was little and her cousin has always emphasized how beautiful she is and constantly repeats to her that the day he gets married it has to be to a woman as sexy as she is. It's his birthday and they have a pretty wild party at his house, all his friends go with lots of liquor and by midnight they are all very drunk. The cousins start to dance very close and kiss each other without wanting to, that makes them very horny and they go to his room and there besides kissing they put their hands inside their underwear and start to fuck. He ejaculates on her mouth.
