Billy had obtained satisfaction. But the feeling had come too quickly and was too quickly gone. He was like a kid who had broken into a candy store and devoured only one candy. His appetite demanded, more and, since it was there for him to take, he wasn't about to leave until he had gotten his fill.
Like most boys his age, Billy had thought a great deal about sex. He had heard things and read things, and he had watched his mother and Mr.
Simpson fucking last night. Though he felt that Kathy wasn't the ideal person to have sex with, since she was his sister, she was the only female available to him-and her body did turn him on. As for the risk of her becoming pregnant, he had a natural fatalism regarding that. Anyway, as he had told her, if it were going to happen it probably had happened already.
Billy crawled backward, withdrawing his soft cock from his sister's wet little cunt, and he lowered his face to her tits. He began to lick at her nipples, which remained very hard.
New sensations of pleasure lashed at Kathy's nerves. The process of stimulation was beginning all over again, starting this time from a higher level of intensity.
Kathy whimpered and fretted, but she allowed Billy to lick her young, firm tits. His wet tongue swabbed her sensitive nipples; his lips seized the little tips and tugged. Moaning, she writhed, seeking further stimulation and at the same time seeking to make her brother stop.
Billy derived great pleasure from mouthing his sister's titties, and this pleasure expressed itself in the form of a new, thrusting hard-on. He raised his bead and crawled forward, bringing the end of his cock into contact with the slightly open and moist lips of Kathy's cunt.
"No!" she cried. "Oh, Billy, we can't do it again!"
"Keep quiet!" he growled. "If Aunt Maude comes in, we've had it."
"But Billy, It's so wrong and-ooohhh!"
Again he was inside her, his slippery, hard cock gliding deep. This time she felt less discomfort. She was more open an4 more thoroughly lubricated, by his cum as well as by her own juice. The pleasure was immediate and strong.
Billy felt less giddy this time; he was more in command of himself. The fantastic sensation of slowly stroking his cock into his sister was so good that he decided to follow with more slow strokes rather than to fuck her briskly from the start, as he had done the first time.
He withdrew his cock nearly all the way, and Kathy gasped. She didn't want to break the contact at that moment, though she could easily have done so, but waited with held breath, anticipating another deeply penetrating thrust. Billy gave it to her, slamming his hard cock all the way home in his sister's tight cunt.
"Aaahhh!" she cried, and clutched him. Her knees lifted slightly.
"Feel good?" he asked, looking directly into her face, his eyes tense.
"Yesss," Kathy hissed. "But we shouldn't."
It seemed so strange to have him above her-on her and in her-looking down at her that way.
He pulled his prick back a second time, then slid the long column slowly into her cunt again. That felt very good to him. He stroked out and in, out and in, setting a slow, steady rhythm and penetrating deeply with each thrust.
Kathy gasped, then whimpered. Her hips began to move cautiously against him. She was really getting with it now. She moved more actively, taking her brother's cock even deeper into her teen body.
Soon they were driving their crotches together. Kathy punctuated the rhythm with sharp little sounds. She clutched Billy hard around his back.
As he speeded up, she felt that she was right with him. Something was going to happen this time. She knew it.
"Billy… ooh, Billy!" she panted.
He drove his hot cock into her-rocking, slamming, screwing, fucking, making her come!
Kathy let out a blissful sigh as the warmth of orgasm enveloped her. She trembled ecstatically. Her cunt spasmed around her twin brother's prick. All tension melted away, giving her an ecstasy she had never before known. Billy's hot spurts, deep inside her, added the final touch to her rapture. She had never even imagined that such boundless pleasure existed.
Now she knew what sex really meant, and this was a revelation that changed her life.
As soon as Billy had pulled his cock out of her and rolled onto his back, she bent over him and began to cover his face and neck with kisses. He was amazed.
"Oh, darling, darling Billy!" Kathy exclaimed as her mouth darted from place to place. "You were wonderful! It was so good!"
"You really liked it, huh?" he said, proud of himself, but still mystified by the suddenness of his sister's change of heart.
"Ooohhh, yesss! I want to do it same more! Oh, Billy!" she kept kissing him.
Now she grabbed his cock and began to tug at the limp, wet organ, trying to induce a new hard-on.
But her efforts were in vain.
"Billy, make it hard!" she begged.
"I can't. Not right now." His cheeks were flushed as he looked at her, his hair falling partially in front of his face.
"But I want to fuck some more," she said. "Oooh, that was nice!"
Billy had been thinking of what he had seen his mother do with Ray.
"Maybe you could make me hard," he said, "if you wanted to put your mouth on it."
She stared at him and her lower lip slackened. He grinned and said, "Well, Mom did it."
"Yes, but-"
"Go ahead," he urged, becoming more excited the more he thought about the daring act.
Kathy thought about it also. Then suddenly she shook her head. "No, I couldn't," she said with a tone of finality.
"Why not?"
"Because it's nasty."
"Mom seemed to like doing it to Mr. Simpson."
He grasped his limber cock and wiggled it. "Come on, Kathy. Just suck me a little. I'll bet you can make me hard in a hurry."
"No."
Billy stared at her. He decided that he wasn't going to accept no for an answer. He would make her do it!"
He reached out and grasped her around the head. She began to struggle, but she succeeded in pushing her head down so that her face rubbed across his cock and balls. That gave him a little thrill.
To Kathy it was humiliating. His cock smelled strongly after having been used twice inside her cunt, and it was slimy with their mingled juices. She turned her lips inward so they wouldn't touch the wet cock, and she twisted out of her brother's grasp as quickly as she could.
"If you're going to treat me this way, I'm going to get up," she announced, and tried to get off the bed.
But Billy grasped her once more and threw her roughly onto her back. She kicked, but he managed to swing on top of her without catching a clout in the balls. He settled onto her waist.
"What are you trying to do?" she demanded as she stared angrily up at him.
"I'm trying to get you to suck my cock," Billy said frankly. "I won't!" she replied. "It's a ditty, smelly thing!"
"Then I'll jam it into your mouth. And if you bite it, I'll really mess you up. Dig?"
"Billy! How can you treat me like this?"
"Quit acting like a kid," he said. "Mom sucks Simpson's cock, so you can suck mine."
Kathy became very upset. She decided that maybe she didn't like sex after all.
She twisted and thrashed, trying to throw her brother off or to get out from under him. But his position was such that he could easily maintain control. After catching her flailing arms and pinning them to the bed, he crawled forward and placed his knees against her arms, holding them firmly next to her body. He hooked his calves across her wrists and sat on her tits. She, now was completely restrained except for her legs, which could kick but couldn't reach him.
Billy leaned forward against the head of the bed, causing his cock and balls to dangle over his sister's face. She flopped her head from side to side, desperately trying to avoid contact with his cock.
The more she fought, the more determined Billy became to make her stick his cock. It was already hanging forward from his balls, partially erect, and he knew that the moment her warm, wet mouth surrounded the head of it, his prick would snap to rigid attention.
He lowered his body so that his balls came into contact with her chin, and they bounced as she kept turning her head. He leaned on one arm and grasped his cock with his free hand. He smeared it all over his sister's face-across her eyes and forehead, down one cheek and up the other, over her nose and along her lips.
She kept her lips turned inward and made little whining sounds in her throat. But as she struggled in an increasingly vain effort to avoid oral contact with his cock, her pussy started moistening once more. Her cuntlips flared, inviting the insertion of Billy's cock.
But Billy was determined to do something first. He wanted to treat her as he had watched Mr. Simpson treat his mother.
Billy settles down so that his hairy scrotum was spread against his sister's chin. With one hand he held her head in position while with the other he swiped the slimy head of his cock back and forth across the thin line of Kathy's lips.
Then, as he clamped his thumb around her chin, he used his fingertips to spread her lips in front of her tightly clenched teeth. With the other hand, he directed the tip of his prick between her soft, moist lips. As she moaned desperately but found herself unable to prevent what was happening, he worked his cock back and forth between her lips, the cockhead rubbing against her teeth.
The sensitive nerve endings of her lips felt the clammy sponginess of his cockhead, and her tastebuds savored the flavor of his cock while she breathed in its raunchy scent. Very quickly her entire being became permeated by the feel, taste and smell of her brother's prick, and she felt her aversion to it weakening. She thought of how reluctantly at first, then how pleasurably, her mother had sucked Mr. Simpson's cock. The same chaise in attitude seemed to be taking place in her.
"Come on, Kathy," Billy said, breathing heavily. "Take my cock into your mouth."
He wiggled his cockhead against her teeth and enjoyed the stimulation of her lips rubbing the sensitive surface. Though he had experienced two comes in quick succession just a little while ago; the contact with her lips was already causing his cock to swell again.
Though she wasn't aware of willing them to do so, the muscles of Kathy's jaws began to relax, and her teeth parted slightly.
"That's it, baby," Billy crooned. "Open your mouth wide.
Her jaws suddenly snapped, open, and she was amazed to feel her brother's slick, bulging cockhead plunging into her mouth. Her brain whirled with giddiness and she closed her eyes as Billy pushed his prick back on the velvety platform of her tongue. His shaft was completely stiff by now, and its thickness stretched her small mouth. The encircling snugness of her soft lips thrilled him, as did the scraping of her teeth on his shaft. His cock was bathed by her saliva and heated by the warmth of her oral cavity.
She started to gag when he shoved his cock too deeply into her mouth, and he withdrew slightly. That felt better to Kathy.
The copious flow of her saliva was washing all the sexual juices from his prick, giving her tastebuds a treat before the mixture trickled down her throat. She gulped repeatedly.
Having Billy's cock in her mouth wasn't nearly as bad as she had believe it would be. In fact, she was beginning to enjoy it.
She started to suck.
