Dad Creep's depraved mind conjures a lewd fantasy as he watches his step-son change. The boy's lithe body, toned from years of swim team, is a feast for the eyes. Dad Creep can't help but imagine his cock sliding into that tight, teenage hole. He strokes himself, his cock throbbing at the thought. The boy catches him, but Dad Creep just grins, inviting him closer. The boy hesitates, then crawls onto the bed, his eyes never leaving Dad Creep's hard cock. Dad Creep grabs the boy, pulling him onto his lap, his cock already slick with pre-cum. He grinds against the boy, his hands roaming the boy's body, until the boy can't help but moan, his own cock hard and leaking.
