"Of course I understand," he replied. He guided her into the living room and had her sit with him on the sofa. "I want to be your friend. Your mother saw you sucking the dog's cock in the shed and almost had a fit. I calmed her down."
"That's okay," Karen laughed. "I saw her fucking you on the bed."
"You did?"
"Uh-huh. I saw you pushing your big cock into her cunt."
Bob grinned. "Your mother is very beautiful in bed."
"So I noticed!"
"In fact," Bob went on, "I don't mind telling you that she's one of the best pieces of ass I've had in a long time. She thinks I fuck every chick in the office, and I let her think that. But it isn't true. The truth is that she's the only woman who puts out."
Karen saw the humor in it, and both of them roared with laughter. Karen thought Mr. Rix was very clever to get into her mother's pussy that way.
"You're nice," she said, and her blue eyes twinkled.
"So are you," Bob said.
Karen felt comfortable with the man now. She leaned back on the sofa and let her thighs part a little.
"What happens now?" she asked. "Is this where you say you won't tell my mother on me if I let you fuck me?"
Bob laughed a moment. "You've got the wrong idea, kitten. You've been reading too many novels. Sure, I'd like to fuck your cute little cunt, but not if you don't want me to."
"I don't," Karen said, glancing at his hard-on. "Your prick's too big!"
Bob chuckled then and patted her naked thigh. "Quit worrying about it. All I'm trying to do is keep peace in this family. It's time you and your mother came to a mature understanding about your sex lives. You two can be friends as well as mother and daughter – if you work at it."
Karen was mystified. "You mean, my mom is willing to let me fuck the dog if I want?"
"Something like that," Bob said. "What we need from you is a solemn promise that you will never again suck or fuck your dog outside this house."
Karen thought about that for a moment. "Are you saying that it's all right for me to fuck Rex here in the house?"
"Exactly," Bob grinned.
Karen looked suspicious. "And that's all there is to it?"
"Yes," Bob said. "We just don't want the neighbors finding you in the shed, fucking a dog. Your mother could never live that down. This way, if you confine your fucking to the house, no one will ever know."
Karen shook her head slowly, her eyes narrowing. "There must be a catch somewhere. Why would Mom and you let me fuck Rex?"
"Well, there is one small catch," Bob admitted.
"I thought so! What is it?"
"I want to watch you now while Rex fucks you," he said.
"Is that all? You just want to watch me and Rex fuck? You won't try to push your big cock in my cunt?"
"You have my word, kitten," Bob said. "I just want to sit right over here and watch you get your cookies with the dog. What do you say?"
Karen eyed him sitting in the chair across the room. A smile lit up her pretty face. "Okay," she said. "It's a deal. I think it'll be fun to fuck Rex with you watching."
The idea of fucking Rex while the man looked on seemed like a wicked and wonderful thing to do. Giggling, Karen called Rex into the room, and as Bob stared, she got down on all fours and hiked her dress way up onto her back. Bob saw all of her pretty ass and cute cunt just before the mutt mounted her.
Karen caught her breath and gasped as Rex's long cock slid deep into her saucy cunt. Her pussy was still soaked from the fuck and suck session in the shed, and the dog's big prick slipped right up into her cunt.
The feeling of getting fucked – of being watched while fucking a dog, was incredibly exciting to Karen. Bob watching her as she fucked Rex's doggie-prick only made fucking that much more fun.
"Oh, golly!" she panted as Rex pounded her pussy.
She thrust a hand down and started rubbing her stiff pink clit, which was really throbbing now. She grunted and groaned loudly as Rex's cock speared in and out of her cunt rhythmically. Her pussy-lips tightened around the dog's prick and sucked on it as it drilled into her with relentless fury. Even Rex started panting.
Bob sat back and pulled out his enormous prick. He gripped his cock tensely in his fist and pumped it up and down as he watched the massive animal fuck the little girl's cute cunt. The more he watched, the bigger his cock got, and the bigger it got, the faster he jacked it. Karen's frequent moans of pleasure really turned him on.
As his desire and lust mounted, Bob began thinking some rather raunchy things about the pretty teenager. Driven by passion, he dropped to the floor and crawled over to the quivering, humping girl.
"Karen, Karen," he breathed hotly. "Can I just suck your tits?"
Karen's head was tossing from side to side, her hair sweeping the floor. She forced her eyes open and panted: "Yes, yesssss."
Bob lay on his back and positioned himself under Karen's thrusting tits. He pulled her dress down away from her tits and gazed longingly at her tit-mounds. Then she moaned and lowered her tits to his face, finding his mouth with one spiking pink nipple. She let out a howl of pleasure when the man started sucking her nipple.
While Karen fucked her hot cunt on Rex's prick, Bob licked and sucked and nibbled her beautiful tits, helping her to get off a good one.
"Oh!" Karen shrieked.
A second later, her whole body shook and jerked violently as her pussy creamed all over Rex's jabbing, drilling doggie-prick. Rex grunted hornily and fucked his cock harder into her juicy cunt, drooling saliva on her back. His cock swelled up to its fullest and drove faster in and out of her squirming pussy. Bob sucked hard on her firm tits, and she squealed with joy.
"I'm coming!" she cried, twisting her cunt and tits furiously. "I-I – ohhhhhhh! I'm coooommiiing!"
She came and came and came on the drilling dog-cock – so much so that her pussy-juice oozed out of her fucking cunt and leaked down her quivering thighs to her knees. Her fuck-cream felt hot and silky against her flesh, and she moaned as it flowed.
"Ohhhhmmmmm, Mr. Rix!" she panted, fucking her cunt harder on Rex's pumping prick. "If you only knew! Ummmm, it feels so good! Ohhh, you make my tits want to come, too! I'm coming so much! Ohh, Rex – fuck me, fuck me!"
"He's gonna fuck you, all right," Bob said in a strange voice.
The sight of Karen responding so beautifully to a dog-fucking gave the man wicked ideas. He crawled from under the girl's twisting, shivering body and crept down to the fucking animal. He reached under her and dipped his fingers into her cunt-juice. He worked her cunt-cream around over her asscheek.
"Mr. Rix!" Karen gasped. "Wh… what are you doing?"
He rubbed her silky pussy fluid into her tight little asshole, and the feeling was so wonderfully wicked, that she squealed and moaned.
"Mr. Rix! No, no! Stop that!"
But there was no stopping the lust-driven man. He needed to see more of this fucking action with the teenaged girl and her dog. And he wanted to see Rex fuck her darling little ass!
Panting hornily, Bob knelt behind Rex and reached around his thrusting body with both hands. He pulled the dog's prick out of Karen's writhing cunt and held it against her tight little asshole. All of the sudden, the full length of the doggie-prick, all wet and slimy, drilled straight up into her asshole.
"Oh, my God!" Karen squealed, feeling Rex's cock squeeze up into her asshole. "Ohh, Mama!"
At first having her ass fucked was somewhat painful to the girl, and she whimpered. She couldn't believe Rex was fucking his cock into her ass-chute. It hurt a lot for a second or two, then, when the dog's cock had penetrated her asshole, she had to admit that his prick felt pretty good sliding in and out of her shitter as it had in her pussy.
Rex apparently liked fucking her asshole, too, because he started pumping his prick in her ass with powerful thrusts. Bob sat back and watched the massive dog fuck the girl. He envied the mutt, because he would have liked to fill Karen's tight asshole with his own swollen, aching cock.
