His sister came home drunk and fucked him
It was the girl who came home totally drunk and horny. After the whole night of partying, she was the only one of her friends who hadn’t fucked, so she went to her brother’s room and woke him up. She took out her tits and told him to touch them, he asked her if she liked them. The boy was amazed by all this, but he was also getting horny. He had never seen his sister as a woman he could fuck, but after that everything changed. And yes, of course he fucked her. When she got completely naked and spread her legs showing her wet pussy, she realized that there was no turning back, no one could have resisted.
