In a fit of taboo desire, Kris sucks her step brother's massive cock, her big ass grinding against his thighs as she takes him deep. She loves the feel of his hard shaft against her tongue, the salty taste of his pre-cum. She can feel him swelling in her mouth, his body tensing as he gets close. She looks up at him, her eyes filled with lust, and he explodes in her mouth, his cum pulsing out in thick ropes, coating her tongue and filling her throat. She swallows every drop, licking her lips clean, hungry for more.
