Bill began to hunch, driving his cock tip down, and Nancy groaned again as the pain in her ass merged with the exquisite sensations her crammed cunt was giving. No wonder Jack had felt so huge! Her asshole had been narrowed by Bill's cock pressing against the thin membrane separating the twin tunnels.
Jack waited until Bill was bunching up, and then slowly filled her ass again. Nancy moaned and shivered and the two huge, throbbing cocks sank into the twin holes of her crotch, bulging against each other through the thin membrane. Her asscheeks trembled involuntarily. God, they were rubbing all of her nerve endings with their big cocks.
"Ummmm," she sighed, the wet pucker of her ass loosening and making Jack's fucking easier.
"Startin' to like it, Aunt Nancy?" Jack asked, reaching beneath her and grabbing her tits as they squashed against Bill's chest. He squeezed and kneaded the two fleshy tits, then tugged them out so they peered from between the two bodies.
Nancy panted, stuffed to the hilt by her nephews' huge cocks. Slowly she began to lift and drop her hips, circling her big, fleshy ass as the two cocks pumped back and forth in her. Soon she was bucking and writhing with even more energy than her two nephews. The awful pain of Jack's entry had completely disappeared.
Bill, too, was in heaven, for Jack's fucking caused his aunt's cunt to squeeze and flutter thrillingly around his cock. Now her pussy was even hotter and tighter, but just as slippery. Her hot cunt-juice was pouring out, covering his balls as he hunched up against her dropping body; the sloshing and smacking of their furious fucking filled the air.
"Ahhhh, so good!" Nancy cried. "Fuck, fuck!" she wailed. "Both of you, keep fucking me! Harder! Faster! Harder! Faster!"
Her two nephews responded to her eager pleas with all their strength. Bill rolled and pinched her two swollen, rubbery nipples, and pumped her cunt as fast as he could. In his haste, he and Jack lost their rhythm.
Nancy didn't care. She responded to their eager, merciless fucking by swinging her hips even more enthusiastically. She shivered and groaned as she started to cum, her asshole clenching painfully.
Jack and Bill continued to fuck her rippling, constricting holes. In and out the two cocks plunged, filling the air with wet, squishy sounds. The two brothers loved having their sexy aunt pinned helplessly between them, whimpering her joy.
Jack looked down at his thick prick as it split Nancy's asshole. The lips of her shitter were turning in and out with his every thrust, and his cock was shiny with her ass juices. Incestuous ass fucking – nothing like it! He thought, and wished Mary would fuck as eagerly. He'd never seen his wife's asshole, but was sure he'd love it.
Nancy's breath was coming in fast, hard gasps as her dazed mind reeled from her cum. Her nephews were still slamming balls deep into her spasming tunnels, and she whimpered, mewled and wriggled her ass hungrily. She'd never felt so filled before, and knew that in a little while she'd orgasm again. How not to, with Jack pounding his ass-splitter into her asshole and Bill driving furiously up her sucking cunt?
"Uhhhh," Nancy moaned, her entire body shaking from the double-fuck. The constant stuffing and emptying of her ass and cunt was just too much to bear. "Cumming!" she cried.
Jack dropped his eyes to her asshole again. The puckered ring was stretched wide by his cock, but as he watched her thrust, the ring tightened visibly, shrinking and squeezing his cock. Her whole ass was rippling around his embedded cock, giving him incredible thrills.
"Jeez!" Jack cried. "Me, too!" And he shoved his swollen cock to the hilt and held it there as it jerked and throbbed, spewing thick bursts of hot, creamy jism deep into her bowels.
"Ahhhh! Ahhhh-huhhhh!" Nancy walked as she felt Jack's cum boiling into her spasming asshole. His thick cock was bucking in her dark, squeezing ass while Bill's continued to slide greasily in and out of bet cunt.
"How's it feel?" Jack gasped. "You like an ass full of hot cum, Aunt Nancy?"
"Oh, yesssss," Nancy hissed, "love it!"
Bill groaned and tried to tighten his muscles. Shit, he'd wanted to last a lot longer, but his aunt's talented cunt muscles were milking him, trying to suck out his cum. Through the thin wall separating his brother's cock from his own, Bill felt Jack's cock expand and contract as he dumped his load.
That did it. The boy groaned as his balls contracted, and he hammered her cunt furiously.
"Ahhh! Uhhh, uhhh!" He grunted, and then his cum exploded deep into her gut, coating her rippling cunt tunnel with hot, creamy cum.
"Ooooooh," Nancy sighed, loving all the hot, sticky cum that was filling her body. She only wished she had one in her mouth, too. Spurt after spurt of thick cum was drenching her twin holes, and she moaned and squirmed her hips to give both her nephews a special thrill. Jack groaned and fell back, and his cock popped free with a loud smack. Bill's limp prick slid out not long after, and Nancy weakly crawled off his sweaty body. The lips of her cunt and bruised asshole were leaking rivers of cum, and warm, slippery fluids ran down her full, white thighs. She looked at her nephews' limp pricks and licked her lips. She felt herself heating up again.
"Either of you ready for a little more action?" she asked hopefully.
"Oh, Jeez," Jack groaned, "I get feast or famine, don't I?"
Bill raised his head, and he smiled. "Squat here between us," he said. "I'll finger your cunt, and maybe Jack'll shove a few fingers up your asshole."
"One of you play with my clit," she whispered as she got between them and felt fingers crawling between her thighs.
Soon Bill had four fingers swirling in her cunt while Jack ran three fingers back end forth in the greasy socket of his aunt's hot asshole. Nancy moaned and hunched herself against her nephews' wonderful fingers. Bill's free hand was plucking her clit and she could feel another orgasm building in the pit of her stomach. She just couldn't get enough!
CHAPTER NINE
Kim walked through the department store with a flushed face. She was horny, and wished she could feel guiltier about it than she did. But since fucking both her sons, she seemed to need a fat cock stuffed her cunt more and more often. She glanced quickly at Mary, wondering if the scent of her pussy had readied her daughter-in-law yet. To think, Kim mused while pretending to examine a dress, that her own sons had reawakened her sexuality at age forty!
"Are you all right, Kim?" Mary asked, breaking in on the woman's thoughts.
"Huh? Oh, of course, why?"
"Well, you seemed so far away, and you looked so unhappy."
"Oh, I'm fine. Just daydreaming a bit, I guess."
"If you don't feel like shopping any more, we could stop for lunch," Mary suggested.
"I'm not really hungry, but I could use a drink. How about you?"
"Well," Mary looked a bit dubious, then decided that one or two drinks couldn't hurt her. "Okay," she smiled. "That'd be nice."
A few hours later Kim mumbled, smacked her lips, and sighed sleepily. She knew she was on her back, and one hand was between her warm thighs, cupping and rubbing her itchy pussy with gentle, rhythmic insistence. She drifted off again for a while, and when next she woke up, her hand was still holding her wet cunt. Her other arm was numb, trapped by some weight. Wearily, she turned her head on the pillow and saw Mary stretched out beside her on the bed. Her daughter-in-law looked like a woman in need, even in her bra and panties. She was moaning and lurching slightly and onto her hands was pulling at the waistband of her thin panties.
Vaguely, memory returned to Kim. She and Mary both had too much to drink at some hotel bar, and one of them had got the bright idea of resting somewhere for a while. Kim couldn't be sure but he thought Mary had registered for the room.
