FOREIGN FUCK in the jacuzzi! MARRIAGE DESTROYED??

I was on vacation with my girlfriend and her husband. And when she was in the room and lying in bed, I went after her husband. He was already lying naked in the jacuzzi, I think he was even expecting me. His boner definitely told me that he was already keen to get wild with me…

But I don't want to give too much away. I just hope Sonja didn't hear us, because when I let him fuck me really hard from behind, the water was already splashing loudly against my ass. What a brazen, blatant and, above all, horny action was that? Have I now destroyed their marriage?
