"Mom, ohhhhh, Mom!" Jack groaned, hunching his hips as his wonderful mother slid smoothly up and down over his engorged cock. Her big tits wobbled above him, and he stared at their dark tips. Her long nipples were straining outward from the brown circles surrounding them; he caught them in his hands and began squeezing and tugging.
"Unghhhh, ohhhhh," Kim moaned, and joy washed across her pretty face. Her soft asscheeks bounced against his upper thighs with little wet slaps.
"Huhhhhh! Ahhhhh!" Jack groaned again, and rolled his heed from side to side. Then he caught sight of his wife.
"Mary?" he gasped. "M-Mary!" He'd forgotten about her once Kim had settled her succulent, steaming snatch on his face, but now he saw that his young, prudish wife was eagerly lifting and dropping over his own brother's stiff prick! And what was worse, he saw a look of wanton pleasure on her face that was new to him, a look that he had never seen when he was fucking her.
"Shut up, Jack," Kim panted. "Don't yell at me for fucking Bill when you're in the middle of fucking me."
"Yeah, I guess you're right," he said.
"Hey, about letting me have a share?" Nancy asked, shuffling on her knees beside her sister.
"The two of us might kill him," Kim was wriggling her fleshy ass.
Jack looked up at his aunt's mammoth tits and grinned tiredly. "Yeah, but what a way to go. Come on, Aunt Nancy, I'll eat you or lick your ass – whatever you want."
Nancy looked at Kim. "Feel like playing with me a bit?" she asked. "You know, sorta like old times?"
"Why not?" Kim said, eyeing her sister's huge, hanging tits. She thought of the fun she'd shared with Mary, and cursed herself for not approaching Nancy years ago.
Nancy gently lowered her ass over her nephew's face, giggling as her dangling cunt-lips were tickled by his extended tongue. She stared at where he and Kim were joined, where the base of his fat cockshaft disappeared into thick, wet crotch-hair. Above his big cock, Kim's clit thrust out, begging for attention.
"Shall I rub this a bit, Kim?" Nancy whispered, placing her fingertips over the hot, greasy clit.
"Yuhhh!" Kim cried.
Nancy watched her sister's big tits roll and bounce, and tried to hold onto the slippery clit. It slithered away again and again as Kim shuddered and squirmed in an agony of ecstasy.
"Ohh, please! Please!" she kept crying, but Nancy wasn't sure whether it was a plea to stop or not. She decided to continue, and lifted her free hand to grab Kim's left tit. It was soft, warm, slightly sweaty, and most of it overflowed her hand, but Nancy didn't mind. She started milking it.
Jack's lips and tongue were busy while this was going on, and his eyes were open. His aunt's plump ass was never still; the asscheeks flapped and waved as she squirmed in response to his incestuous licking.
"Me, me!" Nancy cried, feeling the start of her orgasm. Kim's fingers reached out for her sister's clit.
The two women plucked and teased each other's clits as their sobs and moans grew louder and louder. Jack bucked his hips faster and faster, and licked and sucked with abandon. He could feel both his mother and his aunt shuddering with ecstasy, and wanted to bring them both off together. He twisted his arms until one hand was at Nancy's ass and the other at his mother's.
"Look at them!" Mary exclaimed, halting her ride on Bill's throbbing prick.
Jack held back as long as he could, but when he felt his balls jump and release their load of cum, he rammed his stiffened middle fingers into both Kim and Nancy's relaxed assholes.
"Yahhh! Owwwwww!" Their simultaneous screams of joy filled the room. Both sisters writhed and fishtailed as their orgasms struck. Jack jabbed their shitters with joy as his thick, boiling cum wads flooded his mother's spasming cunt. His fingers flashed in and out, tugging on the women's tight pink assholes.
"Uhhhhh, wuhhhhhhh!" Kim yelled happily, loving the hot rush of her son's jism in her rippling cunt. She felt it ooze out and smear her wriggling ass.
"Ughhhh! Awwwwww!" Nancy echoed her sister's cries, rubbing frenziedly over Jack's nose.
Her face turned a bright red, her eyes flashed, and her tits flapped.
"Ooooooh, yes-s-s!" Both sisters hissed, wriggling their asses and coming down at almost the same time. They fell forward and hugged each other, rubbing their tits together. Jack slowly pulled his fingers from their assholes.
"Mmmmff," he said. "Gulphhh!"
"Did you say something, dear?" Nancy asked, lifting her big ass from her nephew's cunt-smeared face.
"Yeah," he gasped, "I asked you to get off. I couldn't breathe!"
"Sorry," Nancy smiled, "but I just hated to get up. It's so hard to find a comfortable seat these days."
"Ha, ha – very funny," Jack smiled back and wiped his lips.
"You said that was the way to go," Mary said sweetly, and when Jack turned to look at her, she began bouncing on Bill again.
"Look at me," she cried. "Ride 'em, cowgirl!" And she pantomimed a rider being tossed about by a bucking bronco. Bill grinned and hunched vigorously up at her, joining in the fun. Jack's face darkened, and he started to get up, but his mother and aunt, held him down.
"Want me to sit on your face again?" Nancy threatened.
Kim grabbed lack's balls and held them gently in her closed hand. She tugged them lightly. "You can get up if you want," she said, "but I'm going to keep this hand right here." She looked at her sister. "Think they'll stretch that far?" she asked.
Nancy chuckled, and went on all fours so her tits draped across Jack's scowling face. "Come on," she wheedled her nephew, "get in the spirit of things. We're all one big, happy family now. Share and share alike – you now? It's not so bad, is it? You get your choice of three hot women, and so does Bill. Nobody does without. OK?"
"Mufff-humff," Jack mumbled.
"What did you say, dear?" Nancy asked, lifting her huge tits from his face.
"I said all right," Jack repeated. "Now will you let go of my balls, Mom?"
Kim opened her hand and bounced the fat balls in her hot palm. "I wouldn't mind keeping them for a while," she mused, her other hand stroking his flaccid cock.
"Yet, well – I've grown attached to them, and I'd like to get up."
Kim let go. "Ok," she said, "but bring them back soon."
The two women watched as he went over and sat on the floor behind his wife. He watched her bouncing for a few minutes, studying how her shaking asscheeks opened and closed, alternately exposing and hiding her pretty pink asshole. He'd never seen it before, and was fascinated by the sight of it. It looked as tight and unused.
Mary was keeping her orgasm at a distance by halting her fucking every time it approached. She wanted to savor a real long, enjoyable fuck with everyone watching her. Especially Jack. It was her way of getting even. But she said nothing when her husband indicated his desire to join in. She really did love him, and his cock was nice, so she decided she'd really surprise him by offering to suck him off once he got hard.
"Come on," Nancy said to her sister, "let's see if there's any life left in that wet noodle of his…"
"Maybe if we each took a side," Kim suggested, "and pretended it was smear of cum…"
"And started nibbling!" Nancy finished for her. Jack's heart began to pound at the way his mother and aunt were talking as they slowly crawled toward him. Their huge tits waved in the air above the floor, their asscheeks quivered, and his mouth went dry.
Slowly, their bent heads approached his limp prick. He watched their tongues come out and slide under his rubbery prick, lifting it a little. Their fingers played with his balls. Kim nibbled down from the cockhead to her son's balls while Nancy chewed lightly on the other side and in the opposite direction. Occasionally their full lips met around his spongy cockshaft, and they kissed with Jack's cock between them.
