"Come here," Fred said huskily, grabbing Millie from behind in the kitchen.
Millie turned and smiled. "Not now," she said, glancing out the window to where Laura was sunning in the back yard.
"Why not?" Fred said, wrapping his arms around her waist and pushing his cock against her ass. He kissed her neck and also gazed out the window at his sister. "Laura's built like a brick shit-house, isn't she?"
Millie giggled and pushed his hands away from her waist. "You noticed," she said. "I thought you did."
Fred rolled his eyes and rubbed his crotch. "No questions and no answers," he said, swaggering off to the den. "Nothing seen, nothing heard."
Millie sighed and turned her attention to putting the groceries away. She was in the mood for a good long fuck with Fred, but with Laura in the back yard she wouldn't feel relaxed. And at the moment she wasn't interested in a quickie.
By the time she finished in the kitchen and went upstairs to change the bed linen, Laura returned to the house and Millie bumped into her in the hall.
"What's the rush?" Laura said when Millie almost knocked her down. The redhead yanked her bikini top up. "You almost pushed my swim suit down."
Millie's eyes glittered. "You look like you're in the mood. Are you?"
Laura's eyes clouded. "I'm in the mood to get laid, if you must know. I'm not in the mood for pussy."
"Neither am I," Millie said. "But if you want to know the truth, I just gave up getting fucked by Fred because you're around. Not that I don't love having you here, but I'm in the mood for a good long session."
"I'm sorry," Laura said. "Listen, I'll go out. Just give me a few minutes to change and I'll leave for as long as you need."
"Skip it," Millie said, taking her arm. "I've got a better idea."
Laura followed her down the stairs and into the den. When they entered the room, Fred looked up and smiled. "What's up, girls?" he said, staring at his sister's cleavage. "Jesus, Laura, can't you cover up? You're driving me crazy."
"Oh, every cunt in town drives you crazy," Millie giggled. "We came here to visit with you. Sit down, Laura." Millie sprawled down on the loveseat and patted the cushion next to her. "Right here."
Laura sat down and turned to her sister-in-law. "Now what?" she said.
Millie glanced from her husband to Laura. "Now, this," she said, leaning over and nuzzling Laura's neck.
Laura gasped when the horny brunette ran a series of kisses over her throat and ears. She closed her eyes and tried to push Millie away, but Millie tangled her fingers in Laura's long red hair and kissed her firmly on the lips.
"What the fuck…" Fred muttered when Millie finally broke the kiss. His face was flushed and his mouth hung open. "Are you two lesbos or something?"
"If we were lesbos we wouldn't be in here now," Millie said, yanking Laura's swimsuit top down to reveal her bulging tits.
"Jesus Christ!" Fred croaked when Laura threw herself against Millie. "Jesus H. Christ!"
Millie lowered her mouth to Laura's jugs and sucked one half-erect nipple between her lips. She swirled her tongue over the stiffening blossom and Laura closed her eyes and sighed with contentment. Millie toyed with her other nipple while she nursed on the tit in her mouth.
"Listen, this is crazy," Fred said in a deep voice. "If you're gonna do this, why don't you do it when I'm not around?"
Millie kissed the tip of Laura's tit and released it from her mouth. "Because this is more fun," she said. She clamped her lips over Laura's other tit and squeezed the first with the fingers of one hand.
Fred rose up and walked around his desk. "If you two want to have an orgy, why don't we go upstairs and do it right?"
"Lift your ass," Millie said and Laura raised her ass off the loveseat while Millie worked her bikini bottom off her butt. Millie gazed at her husband and cocked one eyebrow. "I thought this would really heat you up, lover. Does it?"
Fred grinned. "You bet."
By now Laura was naked, and Fred stared with hot eyes at the forest between her legs. Millie rose up and stripped her clothes off and Fred's eyes darted from one to the other. Laura leaned over and flicked her tongue over Millie's tits. Millie gasped. "I can't wait to have your tongue on my cunt."
"That's enough, damn it!" Fred said, opening his pants and freeing his prick from his shorts.
In a moment he was naked too and he pumped his cock while he stared at the two women. Millie and Laura hugged each other and Millie swiped her hand between Laura's legs.
She waved the cuntjuice-damp hand in front of Fred's face. "Like it?" she said.
"Shit, yeah!" he said, closing his eyes and frigging himself.
They moved upstairs to the master bedroom and locked the door behind them. They turned on the radio. If the children came home, the noises they made would be muffled.
They climbed onto the bed and Fred advanced toward the women who were sitting close together. "Get over here, you sluts," he said.
Laura took his cock in her fist and pumped it while Millie reached for his balls. "Heaven, huh?" Millie said, winking at her husband.
"You bet," he said.
The women made him lay on his back and they dropped to their knees in front of him. Millie immediately took one of Fred's balls into her mouth while Laura sucked on his mushroom-shaped cockhead.
"Oh, fuck, it's too much!" Fred moaned, driving his cockshaft into Laura's eager mouth.
Millie wet down his balls with her saliva and took his entire sac into her mouth. Laura sank her lips over his prick and pressed her nose into his curly cock-bush.
Laura made gurgling sounds in her throat as she took his knob all the way in. Millie slobbered over his nuts and let the hair coating them float in her saliva-filled mouth. She released them and stroked his inner thighs.
"Don't bring him off," she said to Laura. "His nuts are jumping around. He's ready to come. Then we'll have to wait for him to get it up again." She patted his belly. "He's not a youngster, you know," she teased. "He can't get it up again so fast."
Fred grabbed her wrist and twisted it. "Bitch! Cunt!" he chuckled.
Laura stopped sucking his cock and reluctantly let it slip from her mouth. "I was dying for a mouthful of come," she said.
Millie and Fred glanced at each other. "What about it, honey?" Fred finally said. "Should I give it to her?"
Millie thought for a moment. "Okay." She turned to Laura. "See what I do for you?"
"Yeah, well, remember, I brought Eric here," Laura said with a sly wink as she pursed her lips and wrapped them around Fred's prick-head.
"Oh, Jesus!" Fred muttered as his cock once again disappeared into his sister's mouth.
"Mmmmmmm," Laura crooned, taking the blunt crown of his prick all the way into her throat.
Millie played with herself as she watched the wanton scene. She decided then that she wanted Laura to be part of their sex life forever. Why not? If she got married again, her husband could join in the fun.
She stopped intellectualizing as she watched the veins on Fred's neck stand out. She loved seeing him so excited. His entire body tensed with pleasure. There was no doubt about it. Having his sister suck him off was arousing him incredibly.
The horny brunette was unable to resist crouching down and licking wildly at Fred's balls. He groaned when her hot tongue lashed his bloated eggs. She tugged gently on the wrinkled skin covering his sac and Laura slid the ring of her lips up and down his cockshaft.
Fred obviously couldn't hold out much longer. He laced his fingers through his sister's hair and pulled her mouth more firmly over his dick.
"Suck it!" he yelled, ramming his prick down her throat. "Suck it!"
Millie felt his balls tighten up in their sac and watched Laura suck the first wad of cream out of his pisser and gulp it into her throat.
"Me!" Millie gasped, grabbing his prick from Laura's hand. "Now, me!"
Laura pulled back, working her lips and tongue over Fred's spurting cockhead and swallowing down his thick jism in a frenzy. Millie finally forced her lips over Fred's cock, but it was too late. Laura had sucked him dry.
In frustration, Millie turned to Laura and snaked her tongue into the redhead's mouth in an attempt to draw some of Fred's spunk into her own mouth.
She darted her tongue around, searching for every drop of jizz she could find and letting the precious drops roll around her own tongue. When there was no more, when she'd sucked Laura's mouth dry, they both collapsed in a heap on either side of Fred.
After a few moment's rest, Laura sat up and motioned to Millie. Millie's eyes widened when the redhead opened her jaws wide. There was a glob of whitish spunk in the middle of Laura's tongue. She'd held it there all this time. Now she was offering it to Millie and the brunette made a lunge for it.
She licked up every drop of come from Laura's tongue and her passion was re-ignited. The two women clung together, tit against tit and arms and legs entwined.
Fred opened his eyes to watch and he grinned and winked. "Give me a show until I rest up," he said.
Laura let Millie guide her onto her back and returned the kiss Millie gave her. They kissed passionately and humped their pussies together, french-kissing and frantically rubbing their bouncing tits.
Millie panted for breath as their erect nipples rubbed together. Laura's eyes burned with excitement as she rolled on top of Millie and sucked one wobbling tit into her mouth.
She ground her cunt against Millie's, and at one point rubbed her knee-cap against Millie's thicket. Their clits met as did their tongues and Laura hungrily sucked Millie's pointed boob.
After a while they changed places and Millie sucked one of Laura's throbbing nipples into her mouth. She noticed Fred staring intently at them and pumping his quickly stiffening prick. She closed her eyes, lost in the wondrous sensations raging through her body. She opened them and faced Fred's hard-on and bit down viciously on Laura's tit.
"Ouch, you're hurting me," Laura said.
"Look what you bitches did to me," Fred growled.
They turned to him and laughed when they saw the size of his hard-on. He let it sway in front of his belly like a crimson salami and his eyes danced with excitement.
"Who wants it?" he said.
"Me!" Laura yelled, releasing Millie and climbing around on the bed.
"Look at prim Laura," Millie giggled. "Hot to trot."
"I need it worse then you," Laura said, stretching out on her back with her legs spread wide.
"You've got it, Sis," Fred said hoarsely as he climbed over her and poised his prick over her gaping cunt.
Laura squealed and moaned with delight as the crown of his cock penetrated her cunt-folds. With one lunge, he was inside her and the sex-crazed redhead wrapped her legs tightly around his back and drew him into the saddle.
Fred sucked in his breath and glanced at Millie for approval. She nodded happily and lay on her side as she watched. She toyed with her tits and squeezed her thighs together as her husband drilled his fuckpole in and out of his sister's gently sucking cunt.
Laura thrust herself against him as he fed his dick into her honey-pot. He moved a hand to her cunt and rubbed her clit and the redhead whined with delight.
Millie moved closer and sucked one of Laura's tits and Laura turned her head and invited Millie's tongue into her mouth. Millie frenched her while Fred's cock slapped in and out of her cunt.
Laura's still-tight pussy massaged Fred's prick like a leather glove and made slick slurping sounds ring out in the otherwise quiet room. Millie made sucking sounds with her lips and tongue on Laura's mouth and at intervals she bent down and swirled her tongue over Laura's jugs.
Suddenly Fred leaned over and clamped his hands over Laura's tits. Millie retreated and slammed her tongue into the redhead's mouth.
Fred rubbed his face between Laura's tits and pressed them against his cheeks. He moved his hands under her ass and brought her cunt up to meet his stroking cock.
"God, I'm dying to give it to you in the ass, Sis," he said.
"Do it!" Millie said.
"No, I want you to stay in my cunt!" Laura cried in a husky voice. "I'm almost there. Don't leave me!"
She writhed her body beneath him, her tits twitching and bouncing as she fucked back at his thrusting cock. Millie moved behind Fred and forced her tongue into his asscrack.
"You can fuck my asshole, honey," she whispered to him.
Laura came then and she shrieked as her pussy vibrated against Fred's dick. He waited a moment and then pulled out of her still-spasming cunt and turned to his wife.
"Bend over and take the position," he said and Millie climbed onto her hands and knees and thrust her butt in the air. Laura watched dreamily and Fred chuckled as he kneaded Millie's ass. "My little assfucker," he said. "Your favorite place, isn't it honey?"
"One of 'em," she giggled. "I just love a jizz enema."
Laura's eyelids fluttered as she watched her brother prepare to fuck his wife in the shitter. He inserted his well-lubricated cock into Millie's bung and the brunette trembled with excitement.
"Tight!" she hissed. "I love it in there! Oh, fuck, honey, give me the rest of it!"
"You want it all?" he teased, leaning over and grabbing one of her hanging tits. "How about another inch? Huh? Nice? Another inch?"
He shoved his fuckpole inch by inch into her clutching brownie. Her passion so overwhelmed her, she was unable to speak. Reduced to grunts, Millie buried her face in a pillow and thrust her butt back at his prick.
"So fucking tight!" Fred grunted. "So fucking tight I won't be able to hold out long!"
"Will you do it to me some time?" Millie heard Laura whisper.
"Anytime, Sis," Fred said.
"Are you gonna talk or fuck?" Millie said.
Fred chuckled as he slowly drilled his cock balls-deep into her butt. Millie craned her neck and grunted as she met his gaze.
"Do you want me to play with your clit?" he said.
She nodded gratefully. There was something to be said for intimacy. Maybe they needed outside stimulation to keep their sex life exciting, but knowing each other well was exciting in itself.
Millie raised her ass into high gear and Fred rammed it with his prick while he toyed with her clit. Laura crouched behind him and tried unsuccessfully to suck his balls into her mouth.
"Come!" Fred growled and Millie grunted in response and came.
He slammed his prick forcefully into her bung and his balls slapped Laura in the nose as she continued trying to capture them in her mouth.
"That's it!" Fred yelled. "I'm coming!"
Millie threw her head back and shrieked as Fred's cock exploded inside her shitter. Her asshole clutched his spurting dick and, even though he stopped rubbing her clit, she came again.
When Fred collapsed on the side of the bed, Laura crouched behind Millie and licked the come out of her asscrack. When Millie and Fred realized what she was doing, they laughed and knew the Mitchell family would always have an exciting sex life.
