My stepbrother prefers my rear end over my partner's

My stepbrother loves my asshole more than me. It\'s not surprising because he has a big dick and I\'m a beautiful teen with a petite pussy. He fucks me hard every time I give him a blowjob. My stepbrother is a horny fucker who loves to bang my pussy and cum in it. My stepbrother is an amateur with a big dick.
