Jimmy's cock felt harder, longer than before, filling her mouth almost to capacity. Jimmy was breathing hotly as he sucked and licked at his mother's juicy cunt, his breath fanning the tight crinkle of her asshole. Sarah whimpered softly and twisted her ass until she felt one of his fingers touch the tight pucker of her hole. With a throaty gasp, she began to rub at his asshole, and Jimmy responded by fucking into her mouth with more vigor, panting into her cunt as he licked and sucked with hunger. When and how it happened, Sarah could not say. She felt her son's finger moving into her asshole, and her clit seemed to blow apart as his lips sucked.
The orgasm surprised her with its swiftness. His finger was halfway inside her asshole, but she felt no pain. What she felt was a delicious sensation of fullness, of stretching. No one, not even herself, had pushed anything into her asshole until now. As she came against Jimmy's mouth, she pressed up as hard as she could into his face, and his finger slipped completely into her asshole. She felt it moving in and out, finger-fucking as if it was her cunt. She couldn't believe how good his finger felt inside her asshole. Her orgasm was more intense than ever, almost so hard and exquisite, it was unbearable.
Feverish and coming so beautifully, Sarah didn't think, but thrust one of her fingers into her son's asshole quickly. Jimmy gasped into her convulsing cunt, and rammed his cock down deeply into her mouth. Sarah almost choked as the swollen head of her son's cock slipped past her throat, his balls smashed on her nose. She began to slide her finger in and out of his asshole. Jimmy's cock jerked about inside her mouth, and then she felt him stabbing his finger in and out of her asshole, fucking it the way she was his. She sucked very hard on his cock, her son's tongue ramming in and out of her spasming cunt as he finger-fucked her asshole.
When Jimmy came, it was a wild, hot flood of come-juice. Spurt after hot, thick spurt ran into her throat. She gobbled with mindless greed, swallowing wetly, straining her cunt into his face, the friction of his plunging finger on the ring of her asshole making her come and come in a series of orgasms she didn't know she was capable of. Her mouth filled with her son's scalding juices, but now she could swallow it all, never, losing a precious drop.
As his cock softened in her mouth, she relaxed, letting her legs down but flung wide apart. She slowly pulled her finger out of his asshole, her arms spreading outward from her trembling body.
Although saying nothing, but giggling in a naughty, little-girl way, Sarah suddenly swung her legs over her son's face, turned toward his feet. She sat down, her son's face between the spreading cheeks of her ass.
"Kiss me right there, Jimmy," she breathed in wanton passion.
Jimmy couldn't answer her. His mouth was smashed against her asshole.
He caught her thighs with his hand, and began to kiss about her asshole, making Sarah squirm and twist, squealing in pleasure. Her cunt pushed at his chin, and when she felt his lips part, and his tongue probe her asshole, she gasped loudly. Her right hand shot down to his cock, pulling and stretching it. She bounced her ass into his face, his tongue lapping at the crinkle.
"Ahhh, Jimmy, baby!" she cried out, feeling his cock harden in her fist. "Ooooh, kiss my ass, Jimmy! Kiss my hot ass! Touch my asshole with your tongue… oh, yes, Jimmy! Lick my asshole!"
Jimmy's tongue lapped feverishly at his mother's asshole, his cock turning hard in her fist. He shoved the tip of his tongue against the crinkle, and Sarah pressed hard into his face. His tongue slipped up her asshole, making her cry out. She tried to hold her ass up so he could breathe, but her excitement made her sit down hard and tight.
"Ahhhhh, your tongue is up my asshole, Jimmy!" she whispered. "I can feel your tongue in my hot asshole!"
Jimmy clung to her thighs, working his tongue in and out of his mother's clasping asshole furiously, his cock straining in her jacking fist. Sarah leaned over and lapped the smooth head of his cock, taking it into her face.
With a cry, Sarah jerked her mouth off his cock, then her ass out of his face.
"In the ass!" she moaned, sliding down his body, the heat of her cunt and ass on his flesh. "I want to feel your cock up my ass, fucking my asshole!"
Jimmy lifted his head and watched his mother squatting over his cock, her back to him. Sarah held his cock at the base, rubbing the smooth head about her crinkled asshole, holding her breath. The touch of her son's cock there sent exquisite shivers through her. She placed the swollen head of his cock against the tight ring of her asshole, and slowly pushed down. She gritted her teeth as she felt the pressure against the tightness of her asshole, and increased her downward pushing. She closed her eyes and sat down, the head of her son's cock sliding up her asshole. She gasped at how her asshole stretched, feeling his cock pulsate so hard halfway inside her.
"Ohhh, Jimmy!"
She lunged down.
A scream ripped from her as his cock filled her ass completely, her cunt smashing onto his balls. She froze as she sat on his cock, almost afraid to move. She felt no pain, but a delicious feeling. The ring of her asshole flexed and squeezed the base of his cock, making Jimmy moan in delight. He placed his hands on her spreading hips.
"Fuck me, Mom!"
"Ahhhh, baby!"
Sarah lifted her ass, and Jimmy watched his cock pull outward, seeing the ring of her asshole closed tightly about it. She lifted until the smooth head almost came out, and then rammed down onto his cock quickly. Squeals of surprised ecstasy boiled from her tight throat, and she began to bounce frantically at his cock, fucking him with her asshole. Her cunt dripped hot juices until his balls were smeared, drenched by them. Her asshole burned and spread and his cock filled her so good Sarah couldn't believe the sensations it gave her.
"Oh my God! I'm getting fucked up the ass," she whimpered. "I don't believe I'm doing this!"
"You're doing it Mom!" Jimmy groaned. "I can see my cock go right up your asshole! You're getting fucked in the ass, all right!"
Swinging her ass about, Sarah kept up a relentless up-and-down motion on his cock, fucking him in a sluttish way she didn't know was in her. The depths of his cock made her mind spin with erotic ecstasy.
"I'm getting ready to come!" she screamed out. "I can't believe this! Cock in my hot asshole… and it's going to make me come! Ohhhhhhh, Jimmy, this is wonderful, so wonderful!"
Leaning forward, Sarah braced herself with her hands near Jimmy's knees, and humped up and down, fucking on his cock in a frenzy. Jimmy stared at the way his mother's asshole flew up and down his cock. The hot tightness, the squeezing her asshole was making, caused him to grit his teeth and arch his hips upward.
Sarah cried out, the ecstasy of her son's cock inside her asshole making her shake, her ass gyrating lewdly. Her tight tits were bobbing, her nipples straining. She looked between her knees, but only saw the silky hairs of her cunt smashing at his balls. Her pussy was vibrating as if it had a cock inside it, too, and her asshole was burning with such sweet fire, her cunt felt as if it was going to burst.
"Jimmy, I'm about to come!"
"Me, too, Mom!" he groaned.
Sarah's ass seemed to move with a blur up and down, smacking in a fleshy sound each time she lunged onto his cock.
She lifted her head, a scream coming from her as her cunt exploded, making her asshole grip and squeeze Jimmy's cock.
"Mom, take it!" he yelled, spurting hot juices into her asshole.
Sarah screamed again, the spurts of her son's come-juice searing the sensitive, delicate walls of her asshole.
"Hey, anybody home!"
With a yelp, Sarah yanked her asshole off her son's still-gushing cock. Without saying anything, leaving her dress and panties on the floor near her naked son, she ran for the only place she could hide… out the back door.
