(Author's note - this follows the last story, "Diana Investigates" As the tags indicate, there is pee drinking involved.)
When James returned to her bedroom, at Buckingham Palace, Diana was waiting on her bed, lying on her side, her head resting on a pillow. James moved to the side of the bed, standing silently in front of her. He leaned down to kiss her and then resumed his stance.
"My turn," Diana said softly with a smile.
She eased over to the edge of the bed, lifted her head and opened her mouth. James waited until she engulfed his limp penis. This was one little game that she enjoyed, worshipping him.
He watched her bobbing her head back and forth, slowly taking him inch by inch as he became harder and harder. Normally she would get him erect and then roll over on her back so he could mount her missionary. She continued sucking him a little longer than usual before she stopped and looked up at him.
"I owe you a special favor; would you like to finish....?"
"No, I want to use your body and come deep inside you," he replied.
Diana started to roll onto her back, but James stopped her.
"Don't move; stay on your side."
He climbed onto the bed behind her. He knew she would still be wet from the orgasm he had just given her. As she lay on her side, he moved her into a fetal position and pressed the tip of his erection between her thighs.
The position and the angle surprised her; her tightness aroused him even further. He eased his cock inside her and then began slow thrusts against her. He put a hand on the top of her thigh and probed her deeply each time. The sounds of sex, the scent, the moans, filled the room.
Diana moaned more and more as James continued stretching her. Her warm wetness let him slide in and out with ease. After a long time, but sooner than usual, James could feel the inevitable about to happen.
"I can't hold it much longer, my love," he panted.
"On my nipples, then," she replied.
James pulled free as Diana rolled onto her back. James moved forward as she moved towards him, underneath as his hand aimed his cock. Groaning with each spurt, he covered each of her nipples with his cum until he was spent.
He leaned down and kissed her passionately. She returned the kiss, her arms clinging around his neck.
"I love you so. Why didn't you let me finish inside you?"
"I just wanted to see it; did you mind?"
"Of course not, I was just curious."
"Next time, I promise. I like to feel it in me, I really do."
James went after a towel and while Diana was cleaning up, Camilla was celebrating with Charles elsewhere, at Kensington Palace.
"Charles, do you know what day it is?" Camilla asked.
"It's Thursday; should you be somewhere else?"
