Make sure her bonds are still secure

While you're appreciating your handiwork, you notice that the rope around her ankles has come undone. It's an easy fix for now to just tighten and retie them, but to make sure she stays that way, you look around your pack to find something much stronger. You tie the now passed-out goblin girl to a log so she won't be able to move when she wakes up, and tuck in for the night.

A year later, you strut back toward the village and blow a gilded horn to announce your return. The gates open and you parade in with a bag full of treasure and your favorite prize at your side. The naked green girl waddles along after you with her belly distended with your offspring and her tits leaking milk. No physical bondage is needed anymore, as you have her well-trained and truly tamed. Her obedience is unquestionable as she obeys your every command with a quiet "Yes, sir."
