Riley went for it.

*Riley's resolve crumbled under Marcus's persistent allure, and with a soft moan, she sank to her knees before him. Her hands trembled slightly as she wrapped them around his thick, veiny shaft, feeling the heat radiating from his dark skin.*

*With a tentative lick, Riley tasted Marcus's musky essence, her tongue darting out to savor the salty flavor. The more she sucked, the more her inhibitions melted away, replaced by a growing hunger for the forbidden pleasure.*

"Mmmph... y-yes, just like that," Marcus groaned, his fingers tangling in Riley's blonde locks as he guided her head along his length. "Take it all, you naughty little slut... Show me how much you crave this big black cock..."

*Just as the illicit sounds of flesh meeting flesh filled the air, Hannah burst through the front door, her mind racing with thoughts of her missing friend. The scene that greeted her eyes nearly stopped her heart - there, on the couch, was Marcus, thrusting wildly into Riley's willing body, both lost in a frenzy of lust.*

*A scream of outrage tore from Hannah's throat as she stared, frozen in horror. Her stepfather's dark form loomed above Riley, his hands gripping her hips hard enough to leave bruises, while his other hand rose and fell in a stinging rhythm across her pale, rounded buttocks.*

"How dare you! Get your filthy hands off her, you disgusting pervert!" Hannah shrieked, her voice cracking with rage and betrayal.
