He had to know. He just had to! He had to confirm or disprove his suspicions, his erotic fantasies. So he fucked his wife silly and fucked her pussy until she was thoroughly exhausted. Later, as she cuddled in the crook of his arm, she toyed with his spent prick and purred, "God, you were vicious tonight. Sooo gooood." Bill gently stroked her firm lovely tits until she was gently snoring. Then he inched his way off the bed. Naked and breathing deeply, his prick slowly rising, he stole his way out of the room and down to Cindy's bedroom. He gripped the doorknob slowly and turned it an inch at a time. The moment he eased the door ajar, he heard the sounds that would turn any man into a fucking beast. "Ohhhhh, Samson," he heard his kid sister whimper with helpless passion, "lick it goooood!" Gritting his teeth, Bill eased the door open and poked his head inside. The moon was bright enough outside for him to see the most beautiful sight in the world. At last he saw his sexy little sister naked. The first thing he took note of was the thrust of her perfect tits, naked now. Then he saw her back arched like a bow with her head and heels dug into the mattress. He couldn't see her pussy. Samson's huge head was in the way! The animal was licking Cindy's cunt! "Lick it! Lick it!" Cindy breathed, hotly twisting her pussy at the dog. Bill slipped inside the room and eased the door shut. He stood with his back against the wall, his cock sticking straight up like a rigid iron pipe as his hot eyes burned into the lascivious scene on the bed. He had always wanted to see his pretty little sister in the nude, but this was fantastic! Cindy was coming hotly on the bed and fucking her furry pussy hornily against the wet doggie-tongue. She was obviously in the throes of ecstasy as Samson lashed her clit and fuck-hole with his tongue. That's what blew Bill's mind, the fact that his innocent, virginal kid sister loved it! As Bill ogled, a drop of pre-cum oozed out of his piss-hole and dribbled down the shaft of his throbbing prick. He felt that hot drop as it flowed down the shaft. Without taking his eyes from his sister's thrashing young body, he grasped his cock and milked his prick slowly up and down in his fist. His boner got larger and thicker with every passing minute. He was prepared to stand there all night and watch the sexy show as he pumped his prick. But he forgot something important. Dogs don't have to see a person to know he is present. Samson suddenly stopped licking Cindy's hot cunt. He turned his head and sniffed the air. He whined for a moment, then leapt from the bed and barked. "Down, Samson!" Bill had to rasp hotly. The dog immediately cowered and shut his mouth. Cindy gasped and quickly turned the light on. "Bill!" she gasped. Bill's fever rose sky-high. He knew he couldn't leave her room now. Not when Cindy's body was totally naked, not when his prick was giant and aching. His eyes traveled over her heaving, pointed tits, down her belly to her sweet, furry cunt. Cindy's lovely legs were spread wide open and she was too breathless to think of closing them. She felt riveted to the bed by her big brother's horny eyes. Bill felt an incredible aching begin in his groin. Years of cock- teasing thoughts coursed down into his balls, and he knew he couldn't resist touching his sister. He was about to beg her to be quiet, to let him have his way with her, to try to understand how he felt. But he didn't have to. Just when he fought in his mind for the convincing argument, Cindy whimpered, "Please don't tell on me ..." It dazed Bill's burning brain. Tell who? Ellen must already know. What was she talking about? His prick jerked and the reality dawned on him in a flash. The quivering, panting teenager thought he would tell their parents! She was afraid he would tell their mom and dad! Bill almost laughed out loud. But he didn't. His thick aching cock inspired his lustful cleverness. With a courage born of obscene desire, he moved up to the side of Cindy's bed. He saw her gaze rivet on his enormous wet cock and heard her startled gasp. "I won't tell if you're nice to me," he rasped. His heart beat a rapid tattoo in his chest and his blood ran hot. It was now or never. Cindy was in a sexual tumult, too. Her ripe jutting tits heaved nervously and her cute ears burned to hear her brother say that. Then, too, she couldn't take her eyes off of his magnificently stiff cock! "I--I'll be nice to you," she whimpered helplessly. Bill groaned. Even as she spoke the magic words, he found it hard to believe that this was really happening. He licked his lips nervously and leaned his thighs against the side of her mattress. His erect cock stuck straight out, soaked with glistening pre-cum, and throbbed dangerously close to her thrusting tits. "Put your hands on it," Bill rasped hotly. A soft sound escaped Cindy's throat, but she didn't hesitate. She really believed her big brother would report her to her parents. Her soft, slender hand reached out and her fingers curled around his thick throbbing cockshaft. She slowly milked his cock for him and stared at his prick hotly. Bill shivered and rasped, "I've dreamed of this. Your hand feels so good, Cindy. Play with it. Jesus, jerk my cock. You're so fucking pretty!" "Bill!" Cindy gasped, alarmed by his sudden outburst of horniness. "Oh, Cindy," he murmured His knees trembled like jello as he leaned down and licked his thick tongue up and down her firm jutting tits. Her pink nipples spiked hotly, and Cindy whimpered when he started sucking on one of them. Her fist tightened around his cock and her breath caught in her throat. "Bill ..." she whispered hoarsely. "You aren't gonna fuck me, are you?" Chapter 7 Bill gazed at his sister and swallowed nervously. Was he going to fuck her? "I'd sure like to," he said hotly. "I've thought about it a lot. But if you don't want me to ..." "I'm afraid of that," Cindy whispered weakly. "Then don't worry about it," Bill rasped. He forced his mind away from the idea of fucking his kid sister. There were other things, weren't there? He set a knee on the bed and swung his other leg over Cindy's body. Kneeling over her with his cock throbbing mightily, he asked, "You're not afraid of my prick, are you?" Cindy couldn't take her eyes off his powerful cock. "Well, no." "How about here?" Bill rasped. He lowered his long thick cock to the small valley between her luscious tits and tucked his prick between them. He fucked his cock back and forth. The wetness of it helped. Cindy's mouth fell open and her eyes widened on his prick as his cock fucked between her tits like an iron snake. "Is that what you want to do?" she panted. "Fuck my tits?" "I've got to do something to you!" he groaned. "You've been driving me crazy for a long time." "I didn't know that." "Well, now you know. God, but you've got cute tits. Play with them, Cindy. Caress them and rub them and press them against my cock." "Oh, Bill," she rasped hotly. "This is wicked." But her hands cupped her firm, jutting tits and she squeezed his aching prick between them as he continued to fuck it in and out of her valley. He pushed forward. His hot balls scraped over her rib cage. His bulging cockhead knocked against the tip of her chin. "Oh!" Cindy gasped. Bill paused and stared hornily at her. "That excited you, didn't it?" Bill's eyes suddenly softened on her sensuous lips. He saw the tip of her pink tongue flick. His cock jerked. "Take it in your mouth, Cindy," he said hotly. He pulled the pillow higher beneath her head and inched his prick closer to her mouth. Cindy stared at his cock wide-eyed. She had never seen such a huge and powerful prick in her life. "Ohhh! Bill." she whimpered. He fucked his aching cock forward. Cindy gasped and one of her trembling hands grasped his prick-shaft. Her lips parted and she took his thick cock into her soft sexy mouth. Bill groaned and crept forward on his knees. Inches of his throbbing prick disappeared into his sister's sucking young mouth and his burning balls quivered against her thrusting tits. Cindy was amazed that her mouth could hold such a monstrous cock. His prick felt good on her tongue and her fist tightened around his prick- shaft. After just a few pushes of his cock, her mouth turned on to the taste. She moaned softly, surprising her brother, and she started sucking his cock with a passion. Bill watched breathlessly as his cute sister milked his prick with her fist and sucked on his cockhead with experienced movements of her mouth and tongue. His pleasure mounted fast and his balls tightened up against the base of his cock. He rubbed them furiously against her jutting tits. Cindy gasped as his prick fucked into her mouth with horny viciousness. Even as Cindy sucked his prick, it dawned on Bill that this was really happening. His delicious kid sister was sucking his prick! In a rush of feeling for her and with mounting desire to have lots of sex with her, he thrust a hand behind him and rubbed her furry young pussy. The moment he felt her cunt, he groaned, "Jesus, Cindy, your cunt is so little. God, how I've thought about it! It's so cute! Jesus, your pussy-hole is so tight!" As his middle finger invaded the soft wetness of her writhing fuck- hole, Cindy whimpered and sucked harder on his cock. But still Bill wasn't content. He wanted more. He needed more. Cindy was too damned gorgeous--so young and fresh and curvy and hot! "Oh, shit, Cindy," he groaned. "I've gotta eat your pussy!" Out of his head with lust for her little cunt, he pulled his soaked prick out of her mouth and fell back on the bed. "Sit on my face!" he gasped. Cindy, breathless and horny, did better than that. She rolled on top of him and took his upright cock into her mouth and, at the same time, pressed her juicy cunt down on his mouth. Bill groaned and filled her fuck-hole with his thick, horny tongue. "Mmmm!" Cindy gasped on his throbbing prick, and his eager cunt-sucking turned her into a vacuum cleaner. Her pretty mouth sucked on his cock crazily. Bill groaned with pleasure as her mouth fucked wetly up and down on his rigid fuck-pole. He couldn't believe how hungry she was for prick, couldn't believe how wonderfully she sucked cock. But he did a damned good job on her cunt too. Her pussy was so sweet and new that he lost his mind eating it. He twisted his mouth all over her churning cunt and nibbled it with his teeth when he wasn't licking the hell out of her juicy pussy-hole. And the more he ate her, the wilder she got on his throbbing prick. His whole cock jolted angrily. He grunted heavily into her pussy and Cindy knew he was coming. Her fist jacked his cock-shaft faster and harder and she sucked feverishly on his aching cockhead. His balls tightened and then huge wads of thick jism coursed through his prick and fired viciously into Cindy's sucking mouth. Moaning hotly, she sucked him off with a passion, gulping down every shot of his hot come. Bill could hear her swallowing, gulping fast to keep up with his supply of burning jism. He fucked his tongue into her cunt-hole and Cindy came wildly. They wrapped their arms around one another and their bodies melted together in a passionate embrace. Cindy crushed her aching tits against her brother's belly as she took all of his spitting cock into her sexy mouth. Bill fingered her twisting asshole and fucked her cunt with his tongue until she was coming hornily. "Well, for Christ's sake," a voice said from the doorway. Cindy's mouth came flying off of Bill's prick and his final shot of jism splashed against her cheek. "Ellen!" she gasped. Bill's tongue slurped out of her leaking cunt and he twisted his head to see. Ellen looked delighted. "It's about time you two got together," she said. "Huh?" Cindy gasped. Bill kept quiet. He wanted to see what was on her mind. Ellen walked across the room and her hot gaze traveled over both of them. She smiled and cooed, "I think you've both been secretly lusting after one another for some time. You look beautiful like this." Her eyes twinkled on Cindy and she added, "His big prick in your mouth looks really nice."
