One morning, several weeks later, Suzy was fixing lunch, and the telephone rang.
"Dr. Denton's residence," Suzy said, balancing the phone on her shoulder as she buttered a slice of bread with one hand.
"Suzy?" said the faint, trembling voice at the other end.
"Nora!" Suzy said, suddenly alarmed. "Nora, are you all right?"
"Oh, Suzy," Nora answered, her voice a whimper, "I feel awful! I ache all over, and I've got terrible cramps, and I'm dizzy. I think I'm coming down with something. Do you think Dr. Denton would see me without an appointment?"
"I'm sure he will," Suzy said. "You're my sister. Do you want me to come and get you?"
"No," Nora said, "I'll take a taxi."
"Are you sure?" Suzy said, her voice filled with concern.
"Yes," Nora said in a trembling voice, "I'll see you in a few minutes."
"Poor kid," Suzy said to herself as she hung up the phone and quickly finished preparing lunch. "Ron was right. She's been working herself to death at the darned motel. Gosh, I sure hope it isn't anything serious."
Fifteen minutes later, a yellow taxi pulled up in front of the house. Suzy rushed out and gathered her sister in her arms.
"Oh, Nora, honey," she said. "You're shaking like a leaf."
"I'm c-cold," Nora said, swaying dizzily in Suzy's arms. "I hope I'm not making any trouble for you."
"Don't worry about anything, Sis," Suzy said, carrying the shivering girl into the house. "The doctor will see you right away. Everything's going to be all right."
Soon, Nora, wrapped in a thick blanket, was stretched out on Dr. Denton's examination table, alternately shuddering with cold and burning up with fever. Every muscle in her body ached and throbbed, and her head was spinning.
"I want you to take these," Dr. Denton said, handing her two orange pills and a cup of water. While Nora gulped down the pills, the balding blond man took her pulse and temperature. His manner was kind and reassuring, and Nora was relieved, placed herself entirely in his hands.
"Excuse me," Dr. Denton said, disappearing for a moment. He returned with a hypodermic. After squirting the syringe at the ceiling to test it, he turned to Nora.
"I'm going to give you an injection," he said. "This will relieve your pain."
The doctor punctured her arm with the needle, and Nora instantly felt a warm rush of well-being. Her pain was banished, and she felt herself floating in a warm, swirling pool of pleasure.
"How do you feel now?" Dr. Denton asked calmly, withdrawing the needle from her arm.
"Oh, just marvelous!" Nora answered, suppressing a giggle.
Dr. Denton pulled the blanket off of Nora's naked body and raised her feet into the steel stirrups that were attached to the examination table.
"I'm going to give you a pelvic examination," the doctor said gently as he tightened the straps around her ankles.
"Is it necessary, Doctor?" Nora murmured, her closed eyelids fluttering like butterflies.
"I'm afraid it is," Dr. Denton replied, pulling on a pair of thin rubber gloves. "In cases of this nature, we have to explore every possibility."
After dipping his gloved fingers in a jar of lubricant, Dr. Denton parted the lips of Nora's pussy and slid his finger into the tight slick tunnel.
"Do you feel anything?" he asked, studying her face intently.
"Ohh, Doctor," Nora muttered, involuntarily pumping her hips. "It feels… good…"
"How about here?" Dr. Denton said, as he explored her cunt with his lubricated fingers. "Or here? Did you feel that? Any pain at all right here?"
"Ohhhh, Doctor," Nora gasped weakly, sinking into a warm whirlpool of absolute bliss. Her consciousness blurred deliciously and she blacked out for a few seconds, but it seemed like an eternity in heaven.
When Nora opened her eyes she felt – or she thought she felt – a large warm thing slide into her cunt.
"Does it hurt?" Dr. Denton asked, with a strange quaver in his voice.
"No, it feels marvelous," Nora murmured, basking in cloud-like bliss. "What are you doing?"
"I'm giving you an inner massage," Dr. Denton grunted. "It'll help to break up the congestion."
"I… see," Nora moaned, squeezing the intruding flesh with her inner muscles. She felt a series of delicious thrusting movements, then felt a huge mind-boggling gush of warmth that inflamed her cunt.
Wave-like spasms of unbelievable bliss rippled through her mind and body, which had become one. She arched her back suddenly, her body taut with sexual electricity, shuddering with spasms of pure, raw release. The her muscles turned to rubber, her mind melted, and blackness claimed her.
Suzy faced Dr. Denton in his office, wringing the dish towel she held in her hands and asked him the question that was foremost in her mind.
"Is she okay, Doctor?"
"Nothing to worry about," Dr. Denton said, sniffing his fingers. "A touch of the flu, plus a state of complete exhaustion. Don't get me wrong. It could have been serious. Another day and she might have gone over into pneumonia."
"Oh, Doctor," Suzy whispered, her green eyes brimming with tears of gratitude.
"I've got to get back to my patients," Dr. Denton said, toying with his stethoscope. "Why don't you take her upstairs to your room and put her to bed? Sleep is what she needs now."
Suzy carried her sister up to her bedroom and stretched her out on the bed. As she gazed down at the pale lips, lightly parted in sleep, a surge of tenderness and adoration went through her. Leaning over, she softly kissed Nora's cheek, her eyes moistening with tears. She started to leave the room. Then, obeying a sudden impulse, she returned to the bed and pulled the blanket aside.
"Ohh," she murmured involuntarily as her eyes caressed her sister's supple naked body. Nora's tits, tiny but sexy, were as hard as pears. The tiny slit of red flesh between her slender thighs was all but hidden by a thick glossy muff of pussy hair.
"Oh, Jee-zus," Suzy whispered softly to herself. "That's the most beautiful cunt I've ever seen."
She stared open-mouthed at ha sister's snatch, her body tingling with a strange, secret excitement.
She felt herself in the grip of a hot compelling urge, an urge so powerful that she was unable to resist it.
She knew it was wrong, but she couldn't help herself. She stood there, rooted to the spot, unable to take her eyes off of her sister's cunt, unable to deny that she wanted to get her mouth on it.
Completely surrendering to her inner impulses, Suzy peeled off her t-shirt and shorts, and slid onto the bed next to Nora. With the flat of her hand, she ruffled the fleecy muff of pussy hair, keeping a close watch on her sister's face to see if she showed signs of waking.
Nora's eyelashes fluttered briefly as Suzy lightly caressed her pussy, but she remained in a deep, trance-like sleep.
Suzy, trembling with excitement, gently parted the sleeping girl's creamy thighs and lowered her face to her crotch. She blew at the silky hair and prepared to press her throbbing tongue into the sweet tight pussy. Then she paused. Her eyes widened and her nostrils flared as they caught the raw sight and odor of fresh semen.
Without guessing whose cum it might be, or even caring, Suzy pressed her eager mouth over her sister's puffy red pussy lips and sucked with every ounce of force in her body.
She was rewarded with a long slippery glob of warm gelatinous cum that slid slowly into her throat.
"Unng," she murmured softly, holding the sperm wad in her throat. The taste of the rich creamy cum sent her senses reeling, making her blood boil with lust.
Grunting like a little animal, she burrowed deep into the slippery sucking warmth of her sister's cunt, noisily lapping down the hot tangy juice. She ran her tongue along the juicy cunt folds, then played Nora's cunt like a harmonica, gliding her lips loosely over the pouting pussy lips.
She pulled the swollen pussy folds into her mouth and sucked on them, gulping and swallowing juice with mewling gasps of unbearable delight.
"Suck meeee," she heard Nora moan weakly, still deep in a trance. "Suck my pussy."
Suzy licked deep into the sweet flowing crack, fucking the tight tunnel of pussy muscle with her hard tingling tongue. Moving her mouth higher, she caught her sister's tiny rigid clit between her teeth and pulled on it gently.
"Uuumf!" The unconscious girl let out a long shuddering moan and her cunt twitched, filling Suzy's mouth with delicious hot juice.
Just at that moment, Suzy heard a light tapping at the door. Numb with shock and completely out of control, Suzy rose up, her pretty face glistening with her sister's raw cunt essence.
The door opened and Ron stepped inside.
"I brought the groceries," he said. Then he gasped and froze in his tracks, unable to believe what he was seeing.
"Suzy!" he cried.
"Ron…"
"Suzy," Ron gasped, "I… I can't believe it! You've been sucking off your own sister! I don't understand!"
Suzy jumped up from the bed and ran to her befuddled brother. Throwing her arms around him, she pressed her big bouncy tits against his chest. After gazing at him silently for a moment, she raised up on tiptoe, bringing her pussy-tainted lips close to his.
"Ron," she whispered. "Don't talk. Just kiss me!"
