"Now… now…" she panted hornily. "Ohhh, let Rex fuck me now!"
Bob got to his feet and looked lewdly at her. "Someday I'm going to fuck you, too."
"No. No, you're not," Karen rasped hotly, gazing at his enormous wet prick. "Your cock is too big. Only Rex. Ohhh, where is he? I need his prick up my pussy."
Bob went and got Rex, and he bounced into the living room for his daily fuck. Karen whimpered helplessly, shivering with excitement. She got on all fours and invited the animal to fuck her.
Rex mounted her passionately, shoving his big red cock up into her squirming cunt-hole, fucking her silly. Having fucked and fucked for days on end, he had more staying power now. With relentless plowing and plunging, he rammed his fiery cock in and out of her cunt tirelessly, driving the poor girl out of her mind with pleasure and desire.
Bob looked on as usual, pumping his immense prick in his fist, aching to fuck Karen's cute cunt the way the dog was. But the most he was allowed to do was shoot his load of jism all over Karen's tits or down her throat – depending on what the teenager wanted. Still, he swore to himself to get some of her ass one day.
He knew the day was coming, even if Karen didn't. He knew Sheila was building up to a crisis with him. He could see it in her eyes at the office every day. She was thinking of bagging him for her very own stud, and he was fully aware of the way her mind worked.
The moment came one evening about five o'clock at the office. Sheila was on her knees between his legs, milking his stiff prick and toying with his nuts.
"Bob?" she cooed.
"Yeah, Sheila?"
"We've been having lot of fun together lately."
"We sure have," he agreed.
"Even Karen likes it when you visit and watch her fuck Rex. She told me the other night that it really turns her on to see your magnificent cock while she's coming on Rex's cock."
"She's a sexy little bitch," he agreed.
Sheila gave his enormous cock-head a little lick with the tip of her saucy tongue. "Wouldn't you like to live with us?" she purred.
Bob chuckled. "Trying to rope me in, are you?"
"Sure, why not? It would be nice to wake up in the morning and ride your big prick. What do you say? Wouldn't you like to have my cunt, mouth and ass at your disposal?"
"Yeah, I would," Bob said with a smile. "But what about Karen? Would she want me around all the time?"
Sheila giggled. "I already discussed it with her. We're both all for it – if you are."
"Well, I don't know," he said slowly, as if he were undecided and reluctant.
Sheila panicked. "Please, Bob," she begged. "Please say you will."
But Bob looked dubious about it. In desperation, Sheila gripped his big cock tightly and rasped: "I want your prick at home, Bob. Please come live with me. I'll do anything, anything."
"Anything?" Bob pressed.
"Yes!" Sheila gasped, jerking his cock. "I don't care what you want, I'll give it to you if you'll live with me!"
Bob grinned obscenely. "I want to fuck Karen," he said bluntly.
Sheila gasped. "But – she's a virgin! I mean well… she's never been fucked by a man. In fact, no human has ever had her ass. Just Rex."
"I know," Bob said hotly, his stiff prick throbbing. "That's why I want to fuck her pussy. I want mine to be the first human cock up her cunt."
"She-she won't let you fuck her," Sheila said sadly, gazing at his wonderful prick.
"I didn't say anything about her letting me," he replied pointedly. "I said I wanted to fuck her – with or without her permission."
"But…"
"It's up to you," Bob said. "Do you want my cock or don't you?"
"Yes!" Sheila cried. "I don't want some bitch to come along and get your prick! All right. All right. You can fuck Karen – if you can."
"Just leave that to me," Bob chuckled. "I'll need your help, though."
"My help? What? What are you going to do?"
Bob pushed his enormous cock at her sensuous lips and murmured: "Suck me off first, then I'll explain the whole thing to you. Come on, baby, take my cock in your sexy mouth and drink my cum."
Sheila obeyed instantly. She sucked his prick and gulped down all his thick, rich jism, then kissed his gorgeous prick affectionately. The blow-job felt so good to her that she was open to anything he had to say.
She sat on his lap and he finger-fucked her cunt as he hatched his lewd and obscene plan. He laughed a lot as he instructed Sheila on what she had to do to help him get his prick into Karen's sweet little cunt.
Just the thought of having Bob Rix's cock around the house made Sheila willing to do anything for him. Then, too, when he shared his erotic intentions with her, they got her very excited. By the time they reached her house, she was more than ready to see her little girl's pussy penetrated by his magnificent prick.
Bob's plan was a simple one, and he put it into effect the moment he arrived at Sheila's house. They found Karen in the bathroom, taking a shower. Bob winked at Sheila in conspiracy.
"Hurry out of there," he said through the bathroom door.
"Why?" Karen asked over the sound of splashing water.
"Because your mother and I want to see you fuck Rex," he replied.
It was a ploy, but Karen fell for it. She had been toying with her sensitive clit in the shower, and she was ready for some doggie-cock.
She came out of the bathroom in her little robe, looking fresh and pink. Her tits were half naked in the V of the robe, and Bob's cock grew big and strong in his pants.
"You two look awfully horny," Karen giggled.
"We are," her mother laughed.
Bob slipped an arm across Karen's shoulders and led her into the bedroom. "Why don't you just stretch out on the bed and let your mother work you up to a real nice lust?" he suggested.
Karen looked at Sheila, who licked her lips as if she would love to lick her daughter's cunt and ass.
"You want to, Mom?" she asked huskily, willing to spread her legs for her mother.
"Yes, I want to very much."
"Come on," Bob said, goading her. "Let's get this robe off you and turn you on real good."
With that, he stripped the robe from Karen's curvy body, and she fell across the bed with a sigh. Both Bob and Sheila stripped naked, too.
Then both adults started teasing and taunting Karen until she was a writhing mass of flesh. Bob tongued her mouth and played with her tits, while Sheila licked and sucked her pretty cunt.
In no time at all, the horny youngster was more than ready to fuck. Her eyes rolled in her head. Her tits thrust up at Bob's hands and then at his hot mouth. Her ass wiggled constantly on the bed. Her cute pussy twisted and humped against her loving mother's sweet mouth. Her clit stiffened and tingled. Her pink nipples spiked. Her breath left her.
"Bob… Mom… Oh, my God! I'm so fucking hot! Please, please, get Rex. Ohhhhh, get Rex! I wanna fuck!"
Her glazed eyes opened slowly to see her mother hovering over her panting, gasping body. Sheila took her wrists in her hands and eased her arms above her head.
"Mom… what?" Karen gasped, trying to understand.
"It's all right, darling," her mother soothed in a sing-song voice. "You're going to get fucked. You're going to get fucked. Just relax, darling."
But it wasn't Rex she felt getting between her open, hungry thighs. It was Bob Rix!
"Mr. Rix!" she gasped. "No! Oh, please, don't fuck me with your cock!"
Her head jerked around, and she stared up at her mother. "Momma, please… don't let him fuck me with that big prick!"
"It's all right, Karen," Sheila assured her. But she held on tightly to the young girl's wrists so she wouldn't scratch Bob.
