One of the worst feelings in the world for a parent is that someone might take advantage of their child. Eric Lenn knows this because he has a stepson who is now of age. Kieran is beautiful, quiet, and respectful. He will do anything for his Daddy. And because Eric knows the darkness in the hearts and minds of men, he's concerned someone might not just take advantage of his son, but take his virgin ass. How does Eric know of this darkness? He has it too. He sees the way other men look at his boy as they walk by, the way they lick their lips, and absentmindedly grope themselves. And after watching his son jerk off on the internet, Eric knows he has to protect Kieran by giving the boy what he wants... before someone else does. Eric takes Kieran for himself, in his own bedroom, with the curtains open wide so everyone can see. Eric bareback fucks his son, possessing the boy inside and out. He builds, going faster and deeper, filling Kieran full of Daddy cock until he eventually fucks the cum out of the boy. Eric follows, spewing a huge load all over Kieran, marking the boy as his own and thus protecting him from any other perverts prowling the internet.
