You give way

"Damn, you're a tight one," the prince says in that oddly non-courtly voice. Moments later you feel him spitting on your hole some more. This makes you feel humiliatingly undignified. You are considering begging him to stop when he starts trying to push his way in again. The feeling of his cock head on your little hole takes away all of your will to resist. You don’t want the pain, but you do want, it seems, the humiliation.

After a painful struggle that feels like it takes forever, your sphincter gives way to his bulbous head, which suddenly slides inside you. His massive intrusion hurts tremendously and involuntarily, you cry out. Bearing down on you, he continues to force his way in slowly and deliberately. He forces defeated, submissive moans from you every so often as he invades your dignity. The feeling of having your bowels probed in this way is very strange, and exceptionally “naughty,” so you aren't quite sure what to make of it. You realize he's made it all the way inside when you feel his meaty balls rest against your flesh. You emit a sigh of relief that winds up coming out more like a whimper.

Mercifully, the prince pauses and allows you to get used to his girth. As the pain and shock of the initial penetration begins to wear off, you notice that it doesn't hurt that badly any more. Even though you feel very stretched, it's not as bad as the tearing you felt you earlier. Strangely, you feel proud that you have succeeded in giving him what he wants.
