The crown wobbled above the king's head with every thrust he gave the prince. The jewels embedded in the goldwork tinkled in the afternoon sun beaming in through the window. Clouds of dust danced within his bedchamber and the candles flickered in a gentle breeze. Breathing heavily, he told his son. "You... enjoy this cock, because soon I may die in battle, and you're gonna' be missing it." He gave his son another thrust with his monsterous manhood. "You will need to find a comely Lord to fuck alongside. I will find a woman to bear you heirs, you are eighteen and of age. But I forbid you to fuck the woman despite for that purpose. Is that understood?"
"I want you, Your Radiance," cried the prince. "Nothing more."
"My seed is sufficient for now. But in a week, or a month, or a year I will have been slain and you will be empty."
"Yes, Your Grace. But who will he be?"
The king thrusted once more. A trickle of sweat slid from the his forehead to the corner of his lip. Seven hot streams of semen shot into his son's ass as he screamed. "Take it!" And slapped his ass cheeks red.
In response, the prince moaned and shot three long strings of seed onto the crimson bedsheets. The king collapsed comfortably over his son, panting. He took off the crown, flung it on the sheets and began to nibble on the boy's ear softly. Then his neck... then his shoulder.
The king massaged his heir's hips for a moment. "Flip over. We're not done." He slid out his wet cock covered in his own seed and flipped the prince on to his back. He preferred to look into his son's astonishingly chiseled face when he stroked his cock. His deep brown eyes shot up when his father took a frim grip on his manhood and his neck arched backwards, revealing the plump and prevalent apple in his throat.
"Softly, Your Grace. I might burst soon." It was true. His cock was throbbing red and rippling with veins. A nine-inch pipe that belonged to the king whenever he wished. However, the man obeyed and stroked it softly. He lived to serve the prince as much as the prince lived to serve him. The realm depended on their bond. For without it, they are weak and unprotected.
