Siblings, both college freshmen, find themselves drawn to each other's bodies, their hormones raging. One evening, they're alone in their dorm room, the brother's eyes lingering on his sister's ample ass as she bends over her laptop. She catches him staring and, instead of being offended, she stands up, her big tits pressing against her tight shirt, and whispers, "Like what you see?" His cock twitches, and she grins, knowing she's got him right where she wants him.
