He wants to celebrate your submission

You sink further into the bath water as the chief comes closer. "I had heard rumors once of the most powerful healing magic that ever existed. I never thought someone with such power would become my ****," he continues.

Most powerful healing magic? Me? You begin wondering to yourself when you would have cast such a powerful spell on him, much less had learned it in the first place. The only thing you did was fuck him. That was it - you fucked him. Somehow when you fucked him, it healed all of his old scars. You gasp. Like the chief, you'd heard rumors that such a power existed, but you'd always thought it was wishful thinking by horny, lonely adventurers. But no, that power is real, and you have it! The goblin standing in front of you is proof enough.

You are still sorting through your thoughts when the chief continues. "I have ordered a feast to be arranged tomorrow to honor submission to me. For now you should rest up, it's going to be an eventful day tomorrow!"

After the chief leaves, the attendant who installed your piercings helps you out of the bath and gets you cleaned up before ushering you to your next arrangement. You are provided a hot meal in the kitchen. When you finish are sent upstairs and locked in the chief's bedroom. It is dominated by a massive four poster bed in the center. It is large even for your human frame, and you wonder for a moment why such a small creature would have such a large bed. You soon realize, however, that the bed is probably intended to be used by many at once. The rest of the room seems to be a museum to the chief's achievements, with artwork and trophies adorning the walls. Opposite the bed is a large tapestry with an extremely intricate magic crest, which you spend plenty of time examining to little understanding.

You wait on the bed for the next several hours. The light filtering in from the window is fading when the door finally opens and the chief steps inside. He has a huge smile on his face and an erection to match.
