He looked up between her tan, muscular legs, at the engorged labia. The lips of her hairy pussy glistened with the combination of his saliva, her recent cum, and the first sweet beads of her piss. As she began to bend her knees, the lips slowly spread apart, a clear viscous string of her cum draping across her cunt-hole. As she lowered her body she spoke. "You did such a great job of eating we, sucking my cunt and ass, I am going to dribble my pee all over your face. Do you want me to pee on you Little Boy? Ask sweetly and I may grant your wish, Cunt-eater."
He watched a small, yellow bead course the outer crease of her right labia, roll the length of her taint, and stop to collect itself in the pucker of her asshole. His cock throbbed involuntarily, his own drop of pre-cum falling into his curly pubic hair. "Oh, fuck, yes Mistress, please pee, just dribble all over my face, my lips."
There was laughter in her voice, ""You are really such a Nasty Boy, you are dirty. You want to be so dirty. Your cock just gets harder when you think of me peeing all over your face. Your cock is streaming juice as you think about what's coming. Take some of your cock-juice on your baby-finger and work it softly into my ass. Make your Mistress dribble." Lifting his head slightly, he was able to see she was right. A steady flow of clear pre-cum was running the length of his pulsing cock, pooling at its base. He drew his smallest finger from the base to the bright purple head. She watched without expression. But, he knew she was excited with the thought of his little finger wiggling past her anal sphincter. It triggered her ability to slowly release piss, enjoyably release piss.
Her knees bent to ninety degrees, palms resting just above her knee, she positioned her pussy directly over his face. "Like what you see Cunt-Boy? Ready to catch my pee? Put your finger in my ass, softly and slowly. Work it in your nasty way." He obeyed. The glistening bead resting atop his smallest finger was applied to the small, puckered brown hole. He touched her skin softly and, as he expected, her asshole immediately released and the intimate tissue pulsed. The hole repeatedly opened and closed in sensual anticipation. He knew he was about to pleasure his Mistress. Carefully he pressed the finger in only as deep as the first digit, and then he softly worked the finger in circles stretching the asshole wider than the finger was deep. He heard her emit a soft moan and her legs quivered. "Mother Fucker," she whispered. Her right hand dropped between her legs and her squat deepened slightly.
"Ask me to pee on your lips."
"Please Mistress!"
