"Well," Sharon said, watching her brother finger the long organ. "What are you waiting for? Go ahead start pissing!"
As if on command, Stan began to urinate. The yellow stream of fluid shot out over the cement floor, spurting a few inches across the chalk line. He arched his hips forward in an attempt to make the stream reach further out, his face screwing up as he tried to apply more pressure on his emptying bladder. As his mother watched, the yellow stream diminished and dripped a few times. Stan shook the organ, then replaced it inside his pants. "Okay, smart-ass," he said. "See if you can do better than that."
To her horror, Gloria saw her young daughter unhesitatingly unbutton the fly of her tight jeans, then slip them down her smooth thighs. Sharon's fingers slid into the waist band of her, panties and those rolled down to her half-masted jeans. A slight triangle of shadowy pubic hair concealed her pink vaginal lips, and as she stared, still frozen to the spot, yet tingling with growing excitement, Gloria watched her little daughter spread the hair-lined lips of her orifice with one hand. The other came down to sandwich the fingers between the pink folds of flesh. Jutting her hips forward the way her brother had done, Sharon suddenly let fly a stream of yellow-white urine. The trickle grew in force until it was arching toward the chalk line, her pretty face contorted as she strained to force the liquid out with great pressure on her bladder.
The stream of urine splattered on the chalk line for a few moments, then with a grunt of effort, Sharon shot it twelve inches past the line. She shouted in glee. "See! I told you! I told you!" she turned her head triumphantly toward her brother, who was watching the yellow stream cascade past his own mark. "I can piss farther than you… I can… I can…"
Gloria's senses returned as Sharon replaced her panties and jeans. Shaking in uncontrollable emotions, she rushed back to the house, all thoughts of punishing the two children gone from her mind. She could not understand the erotic thrill she had received from watching a childish game, yet she could not deny she was sexually aroused.
An hour later, Sharon and Stan came inside, punching and wrestling at each other. Gloria watched them for a moment, love in her eyes for the healthy beauty of her energetic off-spring. Then, she found herself gazing intently at the clothed groins of her daughter and son as they rough-housed about the room. Under normal circumstances, she would have called a halt to their antics, but not now. Dismissing her earlier feelings of horror, she now gazed intently as they wrestled about on the floor, laughing and squealing in delighted happiness of youth.
With flailing arms and legs, the sister and brother became entangled with Sharon on top of him, her head facing his feet. Stan raised his legs and clasped her head between them, her face very close to his buttocks. In retaliation, Sharon slapped her crotch down hard against his face and wrapped her own thighs tightly around his head. Stan's face was buried against the jeans-covered junction of her slender thighs, and he was struggling for breath.
Gloria's own breath came in swift gasps as she watched the position the two had gotten themselves into. From the dark recesses of her mind, remembrance of times past floated into consciousness. She had been in that very same position a number of times with her husband – only she had been sucking on his penis while he licked and nibbled at her genitals. Once more the tingling of sensual pleasure boiled deep inside her belly, flowing in lava-like particles of sexcharged emotions toward her vagina. She felt herself becoming moist down there, and involuntarily her thighs pressed tightly together. A groan came from deep in her throat as the pressure caused her clitoris to throb deliciously. Unknown to her, she was writhing her buttocks on the cushions of the couch as she watched the two teenagers.
Suddenly a howl of pain erupted from Sharon. Stan relaxed his thighs around her head and she pulled herself free, sitting on the floor with legs spread wide. She ran a small hand across the inner surface of her thigh and looked accusingly at her brother. "That's no fair, Stan. You bit me!"
"I couldn't breath," he answered, grinning. "Besides, I didn't hurt you all that bad."
"You did!" she pouted, rubbing her thigh high up near her crotch. "I'm not going to wrestle with you any more."
Gloria became aware of herself now, and fighting down the intense feeling of impending orgasm in her genitals, she said, "That's enough, you two," she realized her voice was trembling and tried to control it. "Time for bed."
"Bed?" Sharon said, her eyes blazing with anger. "It is not, Mother. It's only eight o'clock."
"By the time you get your bath over, it will be time for bed." Gloria insisted firmly. "Besides, you two have been terribly rowdy tonight."
"Aw, gee whiz," Sharon pouted, getting to her feet, still rubbing at the spot where her brother had bitten her.
"That's enough, Sharon," Gloria said, her eyes moving down the slim body of the youthful girl to watch her rub. "Did Stan bite you very hard?"
"Yes," Sharon replied, glaring at her brother. "He bit me so hard, it still hurts."
"You should be ashamed of yourself, Stan," Gloria chided her son. "Now, both of you… git!"
Still pouting, Sharon entered the hall bathroom and started the water for her bath. As it ran into the tub, she removed her clothing. Naked now, she sat on the commode, waiting for her bath to fill and examined the teeth imprints on her inner thigh. A light knock on the door came to her as she rubbed the spot tenderly. "Yes?" She called out.
"It's Mother, dear," Gloria said softly. "I want to see where Stan bit you. It could be serious."
"Aw, it's not so bad, Mother," Sharon said, but she unlocked the door and allowed her mother to enter the steam-filled bathroom. "He didn't bite me very hard."
Gloria stared at her naked daughter, and immediately her knees grew weak as the intense feeling of impending orgasm swept over her once again. The pert breasts swelled out in a slope, erect pink nipples standing in firm invitation, then tucked under lusciously. The narrow, flat waist and stomach flared out into the beginning roundness of full womanhood and Sharon's long thighs appeared so creamy smooth, they were downright obscene. Two small strips of white skin gave evidence of her golden tan. A thickening bush of pubic hair curled in soft ringlets about the pink lips of her little girl vagina. The image of this beautiful girl arching her pelvis forward and urinating burned into Gloria's mind like a branding iron. She stifled a moan of growing lust and pressed her hand hard into her stomach.
"Are you sick, Mother?" Sharon asked, concern in her voice. She had never seen the weird expression on her mother's face before, and not understanding it, she reached out to hold her mother's arm.
"No… no…" Gloria said, trying hard to control the tremor in her voice. "I'm all right. Now, let me see where Stan bit you."
Sharon twisted her right thigh outward, bending the knee and jutting her pubic mound forward. She pointed to the faint teeth marks on the smooth inner surface of her thigh.
Gloria knelt down and peered at the marks, seeing they were only an inch from her daughter's genitals. She looked at the teeth marks only for a very short moment. What she wanted to see was the delightful moistness of the luscious vagina hidden between her daughter's thighs. And this she gazed at for a very long time as Sharon stood in the awkward position.
Finally she stood up, knowing that if she didn't leave – and soon – she would experience a climax simply from looking at this lovely hair-lined feast. "It isn't bad at that, is it?" she said in a quaking tone. "Still, he shouldn't have bitten you." She stared down at her daughter, then without realizing she was saying it, she blurted, "Sharon, you just march right in there and bite him back!"
