Sam Bourne, the studious stepson, finds himself in a predicament when his blue-balled lust for his stepsister's friend, Canela Skin, becomes unbearable. He seeks her help with his math homework, hoping to distract himself. Canela, noticing his discomfort, playfully suggests they take a break. She straddles him, her short skirt riding up, revealing her lacy panties. Sam's cock tents his pants, and Canela grins, unzipping him and freeing his throbbing erection. She takes him into her mouth, her tongue swirling around his sensitive tip. Sam grips her hair, guiding her as she sucks him off eagerly. She takes him deep, her nose pressing against his abdomen, before pulling back and letting him cum into her mouth, swallowing every drop with a satisfied moan.
