"Well, maybe I can't get your cock up my cunt," she said suddenly. "But I can sure get it in my mouth."
A moment later, she had the puzzled dog flat on his back with his legs sticking up in the air. She cuddled onto his big belly and fondled his erect prick with interest. She licked her lips and swallowed nervously. She knew she was going to go through with it. She had to. Rex's doggie-prick looked so fucking good!
She leaned closer to his big red cock and gazed at it up close. This gave her a sense of belonging to the group of girls at school who were always bragging about the pricks they'd seen or touched or sucked or fucked. Now she had a cock of her own!
She smiled slowly at the thought. What if the girls could see her now! Wouldn't they be envious! Rex wasn't like those silly boys who shot their loads of jism so fast. She'd heard girls complaining about that. One of her friends told her sadly that she had been toying with a boy's prick and it shot cum all over her new dress. What disappointed the girl was that she'd wanted to play with the boy's cock for a long, long time.
Karen giggled softly and ran her fingers up and down the stony length of Rex's hard-on. His prick felt good against her fingers, and she took it into her fist. She slowly jacked his cock, watching it closely. She noticed that the dog's nuts kept tightening up at the base of his cock and that his prick kept getting thicker and larger.
"Goodness," she gasped, amazed. "Girl dogs must love you, Rex! What a big prick! I'll bet you fuck them till they're crazy, you demon. I wish you could fuck me. Isn't that wicked? But it would be nice to fuck, wouldn't it? Ohhh, I know it would! My pussy's so hot now!"
Her breath was hot, too – hot on the end of Rex's nearby prick. She took a breath, smelling his male muskiness, and it made her lips tingle. She licked her lips, and while her tongue was out, she thought she'd go ahead and have a taste of cock.
She slithered her tongue out farther and let the tip of it lick a little at the doggie-prick. Rex growled – not angrily – more like he wanted her to lick his cock.
Karen giggled at that. She liked Rex to lick her pussy, didn't she? Boys liked to be blown, didn't they? Girls like to have their pussies eaten.
Slowly but surely it became the most natural thing in the world for her to suck Rex's cock. That's what she needed was confidence, assurance and desire. She got it all as his doggie-prick throbbed in her hand and jerked when she licked it.
Karen slipped her cheek across Rex's belly until his cock-head brushed her soft lips. She opened her mouth and let her tongue slip out again. Holding his throbbing cock in her tight fist, she started licking her tongue up and down and around his bulging cock-head. His thick red cock-meat grew thicker and hotter, and he started whining with animal pleasure.
The taste of dog-cock surprised Karen. She discovered that she liked it. Her tongue felt sensual and her lips started to tingle until she knew without a doubt that she really wanted to suck him off. She wanted a cock in her mouth – any cock!
She slipped her lips down over Rex's stiff prick and took it into her mouth eagerly. She slipped her hand back toward the dog's hot nuts and jacked his cock-shaft steadily as her mouth began a slow, juicy sucking up and down over his cock-head. The dog growled low and started fucking his cock in and out of her softly sucking mouth.
That drove Karen wild. Even on his back, the animal knew how to fuck! His big haunches started grinding and moving rhythmically, and his enormous prick kept sliding between her soft lips. She closed her mouth tighter around his thrilling cock.
She moaned softly and closed her eyes, making believe it was a boy's prick she was sucking. With that fantasy in mind, she became quite a good cocksucker. Visions of boy's anxious pricks danced in her feverish mind, and she sucked the dog-cock with gusto.
She pushed her hair back and increased her cocksucking tempo. Hot moments passed, and she discovered that she liked sucking cock. Rex's big, thick prick felt good between her lips, probing inside her hot mouth. She moaned on his boner and gave it a series of little licks with her tongue.
The dog's cock enlarged considerably in Karen's mouth, and that excited her. With feminine instinct she knew the dog would get terribly excited if she continued sucking his prick. She knew he would eventually shoot a big load of cum in her mouth.
She remembered her concern earilier about having Rex in bed with her, coming all over her sheets. She laughed on his cock now, because she realized the solution to that silly problem. All she had to do was catch his jism in her mouth!
With the doggie-prick slip-sliding nicely in and out of her hot mouth, Karen wanted to eat his jism now. She started lashing his drilling prick with her saucy little tongue as he mouth-fucked her. Her lips tightened around his prick. Her tongue flew across his prick wildly. Her fist jacked his cock up and down viciously.
Rex started jerking under her, and as she sucked his horny cock, she thought of dogs fucking. With her mouth full of dog-cock and her mind full of dogs fucking, her pussy creamed wetly and unexpectedly. She squealed around her pet's humping cock and thrust a horny hand on her pussy. She drilled two fingers up into her drenched cunt-hole and fucked it hotly as she blew the dog-cock.
The thoughts of male dogs fucking bitches got her off good. She replayed something she'd seen about a year before. She had watched a big male dog jump a bitch and fuck her viciously. The bitch had whined and whimpered with the strangest, horniest noises, and the big male had fucked his powerful cock in and out of her little cunt relentlessly, without letup until he busted his nuts in her.
The memory excited Karen more than thoughts about girls and boys fucking. Maybe because she had never seen boys and girls fucking. But she had seen dogs fucking.
She sucked Rex's cock harder and faster as her mind replayed the raunchy scene of dogs fucking. Rex howled suddenly, and his cock lurched in her sucking mouth.
"Mmmmm!" Karen moaned, knowing what was going to happen next.
Rex's immense boner fucked into her hot mouth and started jerking like crazy. Huge wads of thick cock-cream pumped into her mouth. She gasped and started swallowing. Jism squirted from the corners of her mouth as she sucked and gulped down Rex's cum. As she ate his cock, she wiped his leaking cum onto her aching tits. Spasms rippled through her pussy as she sucked the dog off and gulped down all his cum. Rubbing the remainder of his jism into her tits, she felt incredibly sexy.
Karen fell back gasping after Rex stopped pumping cum down her throat. "Ohhhh, what a thrill!" she panted, playing with her tits. "So that's how you come! Wow!"
She thought of Rex's cum shooting wildly up a bitch's cunt, and that made her smile. Suddenly her eyes lit up. She sat upright, and her mouth fell open.
"That's it!" she gasped. "No wonder you couldn't fuck me! You have to jump me like you jump a bitch!"
The thrill of discovery made her tits leap. She giggled excitedly and rolled away from the panting dog. She got up on her hands and knees, her soft hair falling loosely around her shoulders.
"Rex," she panted. "That's the answer. Come here, boy. Ohhhh, come here and jump me!"
Rex got to his feet and gazed at Karen for a moment. With a slowness that drove her out of her mind, he plodded around behind her and sniffed her pussy.
"Rex!" she squealed. "For God's sake, jump up and fuck me! You want cunt, don't you?"
The aroma of pussy slowly but surely triggered the proper instincts in the animal. His prick, recently blown and sucked dry of its jism, got hard and began to throb again. A moment later, the dog mounted Karen's lithe young body and started humping his haunches like a piston.
"Ohhhh, that's it!" Karen cried happily, wiggling her ass around. "Good boy! Yes, yessss! Fuck me!"
