Horny teen Harley King, home alone with his stepsister, can't help but fantasize about her tight, teenage body. He imagines her watching him jerk off, her eyes locked on his thick, veiny cock. In his mind, she's on her knees, sucking him off before he bends her over and pounds her from behind, leaving her used and dripping. But reality intervenes, leaving him with only his hand and his vivid imagination.
