"Oh, wow!" he moaned, not moving. "I've never had it so fucking good!"
Robin's pleasure had reached a level of all-consuming hunger. She pushed against Doug's body.
"Get off," she said. "I want to eat your cum out of Wendy's pussy!"
Reluctantly, Doug pulled away from the deliciously tight cunt. His long, thick cock flopped noisily against his stomach. The end of his prick still jerked gently, oozing out tiny, clear drops of fluid from his cum hole.
First, Robin grabbed his cock and ran her mouth up and down the sperm-smeared column of meat, squeezing it to release the last wad of cum. After she had thoroughly licked him dry, she pressed her lips against Wendy's hot, hairy pussy opening, and dug her tongue into the creamy slit.
As Doug watched her eat out the milky gobs of jism, his own desires became hatter and more urgent. He began kneading Robin's ass with both hands, slipping his fingertips over the tight shitter opening.
Robin felt a hot, searing stab of pain as the gigantic, round ball of cockhead squeezed slowly into her guts. She inhaled a quick gasp, causing a mouthful of cum to squirt into her voice-box. She choked and spluttered into Wendy's cunt.
"Oh God, fuck me!" she gurgled. "Fuck my ass into a million pieces!!"
Doug knew that if he rammed forward as he would like, it would more than likely ruin Robin forever. He placed his large hands around her waist and gently pulled her ass toward his crotch. At the same time, he began working his cock back and forth, letting her shitter tunnel grow accustomed to his dick.
For Robin, pain suddenly gave way to delicious, raw pleasure. The size of Doug's cock pressed savagely into her guts, squeezing downward, clamping her pussy walls together.
She raised her face from the steamy, hairy opening of Wendy's cunt and moaned loudly. Silvery webs of sperm stretched from her cousin's pussy opening to her lips and chin. She licked her tongue out to gather the juices, and gurgled them down with another greasy moan.
"Stick it in hard! Shove it in! I love it!" she gasped.
Even though Robin begged for the full length of his prick, Doug thought it wiser to give her a few, gentle strokes before pounding all the way in. He withdrew his dick a couple of inches, then eased back in.
"God, I can't stand it!" Robin whispered, her pussy about to explode with pent-up ecstasy. "Fuck me! God, fuck me… NOW!!"
Doug grasped her waist firmly, and for a couple of seconds stopping all body movement. He inched his prick backward until his cockhead pressed against the tight opening, then lunged forward with a savage, quick thrust.
"You want it, take it!" he groaned, feeling his cockhead slip wetly into her guts. "All of it!"
Robin screamed into Wendy's pussy like a wounded animal. Never in her wildest dreams had she thought the pressure, the pain, and the enormous pleasure could whip together in a sensation of pure, piercing release. It was as if both her shitter and her pussy were the target of icy-blue flames!
Her ecstasy seemed to pour out of her mouth and infect her cousin's hot, cum-stained pussy. Wendy felt the first stirrings of rippling spasms storm into the back of her cunt canal.
"God, I want it too!" she said, sliding downward. "Fuck me!"
As Wendy scooted down, Robin's mouth trailed a glistening path of spit and cum mixed with pussy juice up her body. She clamped her mouth around the jutting breasts, then licked upward, crushing her mouth against Wendy's lips. They gasped and moaned into each other's throats as their cunts ground together, their clits throbbing with staccato beats.
Doug hardly knew what to make of the situation. He still pounded into Robin's shitter, but now he could feel the steamy warmth of Wendy's cunt press wetly against his nuts as they dangled between her thighs.
"Me too!" Wendy gasped. "Fuck me too!" She reached under and forced Doug's nuts into her pussy. New flames jammed into the back of her cunt. "God,fuck me, too!!"
Doug withdrew his cock from Robin's shitter and, humping slightly, thrust it wildly into Wendy's convulsing slit tunnel. His shaft was immediately wrapped in a frothy blanket of fiery warmth. He quickly pulled it out and smacked it once again into Robin's asshole.
Both girls began to wince and moan as his speed increased. To them, it appeared that he had two, large pumping dicks, as each of their holes was getting a tremendously savage fucking.
This new sensation caused Doug to cry out in agonized torment. He suddenly became a machine, a pounding mechanism out of control. He flinched, cried out again, then felt the first thundering glob of sperm explode upward.
"Take it!" he grunted, spearing brutally into Robin's asshole, giving her the first hot gush of cum. Then he withdrew, and rammed forward into Wendy's cunt, "Take it!" he said again. "Take it, both of you fucking cunts!!"
Both Robin and Wendy were in a spasm of total release. Their cunts vibrated together as they writhed around on the bed. Each deliberate thrust of Doug's cock seemed to inflame them even more, until they reached a plateau of sheer, raw climax.
"Uuunnnhhhhh!" Doug barked, pumping the last of his load deeply into their guts. He leaned forward, grinding his full weight against then, then went limp with exhaustion.
It was several long moments before he could muster enough energy to pull away. He fell to his side, thoroughly relaxed and satisfied.
"Man, I've died and gone to heaven!" he whispered with his eyes closed.
Although Robin and Wendy were also spent, a burning hunger for more of his cock flamed in their throats. They knelt between his legs and began licking and sucking the stiff shaft.
"Wha… what are you doing?" Doug asked wearily.
If he truly didn't know, he was to find out the answer to his question a few moments later.
CHAPTER THIRTEEN
Alex came home from the hospital the following day, and his beaming smile could only be matched by Robin's. He lay in his room, trying to relax, but he was much too excited. His sister had given him a real welcome-home treat, but it hadn't lasted nearly long enough.
His cock suddenly sprang to life as he thought of those hungry lips sucking up and down his shaft, gobbling down his sperm.
God, could she suck a dick!
He looked at the clock for the tenth time in as many minutes. He didn't know if he could wait for her to get home from school. His nuts began to ache painfully, demanding release.
"Is that you, Robin?" he shouted, when he heard the door slam, Robin had a concerned look on her face as she bounded up the stairs. "Are you okay?" she asked breathlessly. "You sounded like you were in pain!"
"I am!" Alex answered. "I've had a hard-on all day, just waiting for you to get home!"
"You mean, you missed your little sister?" she asked playfully.
"Damn right, now get over here!" Alex said, motioning with his right hand.
"Wait a second," she said. "I've got to get undressed."
As she began slowly removing her clothes, Alex could almost taste the flavor of sex in the air. He looked at his sister's voluptuous body, the long, lean legs, the taut, upturned breasts, and the golden patch of hair that framed her tight, tiny cunt. He felt another dull ache throb into his nuts.
"Hurry!" he said. "Before I cum all over this cast!"
Robin went over to the bed and pulled the sheet away. She gasped as the thick hard cock came into view. She sat next to him and touched it lightly with her fingers.
Alex flinched. "Oh, baby!" he whispered, pulling her close. "Make me feel good!"
Robin kissed him gently at first, then began licking her tongue between his lips, her own hunger beginning to match his. She grasped his cock at the base and slowly jacked the shaft up and down. They moaned into each other's throats.
