Fucking My step-Brother's Bully

My step-brother has been whining and crying for the last several weeks because his friend has turned into a bully. One day after school, his "friend" shows up at my house, I decide it's a good time to try and convince him that bullying my step-brother is probably not a good idea, and offer him $20. He refuses! He wants to see me in my bra and panties instead?! Well... I would do anything for my step-brother, so I take my clothes off. Soon enough, he has me blowing him, fucking him AND THEN gives me a massive Creampie. Anything for my bro!
