I know your secret, brother. I know you fuck with mommy. I have heard them. I'm better than mommy. My ass is bigger. And I fuck better than mommy. Give me a chance brother. I want to see your cock. It's huge. I handjob you for a few minutes. Then you fuck me doggystyle. You cum after 30 seconds. What the fuck brother? You cum very fast. You must train more. You are a loser. The next day you come back to me. You say you've trained with mommy and you want to fuck me. I ride you with my huge ass breaking your balls. You love your sister's big ass. Your cock feels better. You last two more minutes. Good job brother. You have improved but you still need more training. The last day you arrive and ask me to do doggystyle. You start fucking me very hard, my ass bounces a lot. You love your sister's big ass. You spank me. Your cock feels great. It's very hard and my pussy is very wet. You finally cum. Congratulations brother! You're ready to fuck. You can come train with your sister whenever you want.
