My niece was teasing me so I don't care about the difference of thirty years and gave her what she wanted

Last month, we went on vacation at the beach with my wife and son, and my wife insisted on taking her eighteen-year-old niece as well. when I saw him in a bathing suit, I got excited and had to put myself in the sea so that my wife wouldn't notice. but the little bitch did, and from that moment on she started talking to me. she was playing with the food in her mouth, with her tongue, she wore short clothes and bent down so I could see her ass, she was also looking for opportunities to be alone with me ... until one day my wife was shopping with my son while his niece slept ... I went into the room and fucked her all over, he was moving like a snake with my dick inside
