The scent of desperation fills the air as the sister offers her body to her brother in exchange for cash. She's no stranger to his cock, but this time, it's business. He slams her against the wall, her tits bouncing as he pounds into her. She moans loudly, her pussy dripping with lust and need. He smacks her ass, leaving red handprints as he fucks her harder, her body shaking with each thrust. She comes undone, her body convulsing as he pulls out, painting her stomach with his cum. She counts the money, licking her lips, satisfied with their transaction.
