Under the open sky, Derek Allen, a burly stepdad, propositions his stepson Jack Bailey for a raw, outdoor fuck. Jack's young, athletic body responds, his cock stiffening despite his initial hesitation. Derek takes charge, pushing Jack against the tree, his tongue invading Jack's mouth. Jack timidly sucks Derek's giant dick, his inexperienced throat struggling to take it all. Derek fingers Jack's tight asshole, preparing it for his big cock. Jack gasps as Derek enters him, his ass stretching around Derek's thickness. Derek fucks him hard, his big balls slapping against Jack's ass, their groans echoing in the open. Jack's ass milks Derek's cock, drawing out his cum, which Derek pushes deep inside Jack, marking him as his.
