Darenger McCarthy, the muscular, athletic stephad, takes it upon himself to provide his troubled stepson with a unique form of support. He strips the boy naked, revealing a slim, submissive frame, and positions him on all fours. The stephad's thick, veiny cock stands at attention, ready to teach the boy a lesson he won't soon forget. Darenger lubes up and pushes into the boy's tight, virgin hole, making the boy gasp and moan. He starts slow, but soon picks up the pace, pounding the boy hard and deep in doggystyle, filling him up completely. The stephad's balls slap against the boy's ass as he fucks him raw, breeding him and marking him as his own. Despite the taboo nature of their encounter, the stephad offers words of encouragement, helping the boy learn to accept and embrace his submissive side.
