Robyn was chopping vegetables in the kitchen when Bill came home from school. It was a hot afternoon, and all she had on was a loose, thigh-length smock dress with nothing on underneath it. The fabric was quite light, and Robyn could feel the weight of her braless tits jiggling under it as she moved around the kitchen.
This was just the sort of dress that she could never wear outdoors. It was also the sort of dress she'd had to put away when her son had begun making advances on her. But Bill was cured now, Robyn thought, and it was no longer necessary to conceal the lushness of her body around her own house.
Robyn was in a good mood. Bill hadn't bothered her at all since his first appointment with Carla Newman, and she knew he'd probably feel even better after his second that afternoon. Soon, Robyn thought, her son would be apologizing to her for his obscene, disgusting behavior and then things would go back to normal around her house.
The front door of the house opened and slammed shut, and Robyn felt her son's footsteps thudding toward the kitchen through the floorboards. "Come on in, Bill!" she said happily. "I'm just making up some greens for a nice salad! I could sure use some help."
Bill walked into the kitchen and as soon as Robyn saw the leering smile on his face, she knew that she was in trouble. He was ogling her again, openly. Bill stood in the middle of the kitchen and ran his eyes shamelessly up his mom's perfectly carved legs, hungrily studying the outline of her big, braless tits under the smock.
"I… I said I could use your help with the vegetables, Bill," Robyn said nervously.
"I could use some help too, Mom," Bill whispered. "With something a lot more important!"
He walked up to her, took hold of her wrist with one hand and took the chopping knife out of her hand with the other. Robyn made a surprised, whimpering sound as her son turned her around. Then she gasped as he kissed her, pressing his tongue into her mouth, wantonly sliding his hands down her back to squeeze her ass cheeks through the dress.
"Bill! Bill, I thought you were… what about your appointment with the therapist?"
"What about it?"
Bill pulled up his mother's dress, stripping it from her shoulders before she had a chance to push his hands away. Robyn squealed and blushed brightly, her stacked, naked body again totally exposed to her horny son.
"Bill, you're not supposed to be doing this anymore!" Robyn cried helplessly. "Stop it! Don't touch my breasts like that! No, keep your hands off my pussy! Bill…"
Her words trailed off into a whimper as Bill pulled her to the floor, holding her down with one hand as he roughly stripped off his pants with the other. He was even more of a wild animal now than he had been the first two times, and Robyn could already feel the stiffness of his prick as it pressed onto her thigh.
Bill ripped all his clothes off in a frenzy, leaving himself naked. Wildly Robyn looked around the open-windowed kitchen, realizing that one of her neighbors could easily peer in and see the incestuous fuck scene that was about to transpire on the linoleum floor.
But she didn't have a chance to think much about it. Bill spread her thighs toughly apart, positioning himself between her legs and sprawling onto his mother's gorgeous, tanned body. Robyn groaned as she felt his fat, drippy cock head pushing onto her pussy. Then she shuddered as she felt his prick meat stabbing into her hairy cunt.
"No, Bill, no!" Screaming, she flailed her fists on his broad shoulders. "No, Bill, nnnggg! No, no… nuuunhhhhh!"
But his cock was already inside her, and her son was stabbing the meat deep. He spread his knees on the hard floor, changing the angle at which his prick stabbed into her cunt. He thrust very hard, stuffing her pussy with the thickness of his cock.
Shamefully Robyn felt her cunt getting juicy, the pouting lips swelling and peeling apart to admit the driving hardness of his prick. Submissively the naked mother lay beneath him, her thighs spread and her pussy open. There was nothing she could do about it. The therapy sessions hadn't helped at all. Her boy was still desperately, horny for her body.
"Ah, Mom," Bill groaned. "I love your sweet little pussy so much!"
He humped violently between her legs, and Robyn let out a little whimper as he jammed all of his cock up her cunt. This afternoon Bill didn't even give her a chance to get used to it. Instead he'd just humped into her furiously, making her ass, cheeks bounce and shiver on the linoleum floor, savagely driving the thickness of his prick rod in and out of her buttery cunt.
"Sweet little pussy, sweet little pussy," chanted Bill obscenely. "I love your cunt, Mom! I could just keep on fucking your juicy cunt all night!"
Robyn grimaced and shook her head from side to side, barely able to stand the pleasure of Bill's prick rod pistoning inside her pussy channel. She didn't want to give in to him again, but she could already feel herself getting too horny to stop her lust.
It felt good to get fucked like this. Her pussy was throbbing now, getting juicier and juicier, the velvety sheath clasping and clenching around her teen's driving cock. Involuntarily Robyn jerked her ass off the floor, spreading her legs wider apart and lifting her knees, helping her son sink all the way into her cunt.
"Do you like my big cock, Mom? Fucking you like this?"
"Fuck me, Bill," Robyn panted hotly.
Blushing with shame, the horny mother wrapped her slim legs tightly around his back. Then she started humping her ass like a bitch in heat, groaning and moaning as she pistoned her juice-seeping fuck mound onto the satisfying hardness of Bill's cock.
Up and down her nimble ass heaved, grinding her pussy relentlessly onto the shaft of his cock. All at once, Robyn realized how much she had missed her son's cock. Nothing was better than being fucked like this, as horrible as it was. Bill's long, fat, swollen hard-on, piercing into the innermost depths of her cunt.
Bill groaned with pleasure and intensified the speed of his fucking, hammering his long prick through the clutching sheath of Robyn's pussy. Robyn felt more and more fuck-oil seeping out of her cunt, making the hairy slit gurgle and squish as it sucked around Bill's cock.
"Harder, Bill! Fuck my ass off!" Her huge tits jiggled under his chest as she clawed his ass cheeks, desperately trying to draw another inch of his cock into her buttery cunt. "Bill, I'm cumming! Fuck me faster, Sonny! Please keep on fucking me, I need to cum!"
Bill fucked his mother as hard as he could, panting on her shoulder and relentlessly stroking his cum-seeping prick into her pussy. Robyn's throbbing cunt clasped around the driving cock shaft, trying to hold it into her belly. She heaved uncontrollably beneath him as she felt the heat flowering in her loins, spreading through her wide-open cunt slit.
"I'm cumming, Sonny!" she gasped. "Fuck me harder, fuck my pussy! Unhhh! Oh shit, nnnnggggg! Unh unh, Bill, here it is, I'm cuuuummmiiinnngggg!"
She orgasmed even more violently than she'd thought she would, helplessly exploding beneath the driving thrusts of her son's cock. Again and again her pussy throbbed, spewing musky pussy cream all over his cock.
Bill fucked his mother hard and fast through the duration of her cum, ramming his prick tirelessly into her slippery pussy. Then he pulled out of her and Robyn realized dazedly that he still hadn't popped his rocks inside her. She was still panting with pleasure as he grabbed her hips and turned her onto her stomach.
"Oh, Mom," he sighed. "You've got such a sweet little ass! It's so round and juicy! Your ass is just as sweet as your big tits!"
Bill grabbed the peach-shaped ass globes and spread them wide apart, exposing the pink, puckered opening of his mom's asshole. Robyn tried to see his face over her shoulder, wondering what her son was planning to do. Then she felt something thick and spongy pressing onto her asshole, and knew where her teen intended to fuck her next.
"No, Bill, no!" she cried. "You'll kill me with it! You can't fuck me there!"
Bill paid no attention. He pushed his heartshaped cock head securely into his mother's asshole, spreading the tightly muscled sphincter around the fat shaft of his cock. Robyn grunted as her asshole spread to the bursting point, helplessly stretching to admit the wrist thick cock.
"No, Bill!" She grimaced and bit her lip, feeling the hot pain coursing through her bowels. "You're hurting me! Awww, don't fuck my asshole! It's too big for my ass!"
Bill groaned as he hunched on top of her, bucking his hips. The swollen trunk of his cock speared relentlessly up his mom's ass, disappearing between her ass cheeks.
The harder he fucked his prick into her, the more Robyn's asshole got used to the size of his cock. She moaned as she wriggled beneath him, unconsciously flexing her ass muscles to help him drive his big prick into her asshole.
It felt good now! It was hard to believe, but the pain had already vanished and been replaced by a strange, new lust. Robyn could feel a hot pulsing sensation shooting through her ass tract, making the rubbery walls of her asshole suck tightly around Bill's prick.
Bill buried his cock inside her, his balls slapping her hairy pussy crack as he nailed every inch of his rigid cock into his mother's asshole. For a moment he lay on top of her, letting her sucking ass hole stretch around his rock-hard cock.
Bill pulled out and Robyn instinctively lifted her hips to meet his movements. Slowly he rammed his hard-on back into her asshole, sinking it even deeper into her ass. Bill sighed as he again felt her ass muscles gripping spasmodically around his aching cock. He started reaming out his mom's asshole with long, steady strokes of his blue-veined prick.
"Unnggghhh!" Robyn twisted beneath him, her ass cheeks shaking and her big tits jiggling on the floor. "Oh, Bill! You dirty fucker! Unhhh! Unh, unhhhhh!"
Then it felt good, incredibly good. A hot, undeniable lust had filled her asshole, and her wet pussy thrilled to every thrust batten her ass cheeks. Flushed with shame and desire, the naked mother feverishly started humping, pistoning her asshole onto the satisfying stiffness of her son's big prick.
"Fuck my asshole, Bill!" Robyn cried. "Fuck it, fuck it, fuck it good! My asshole's all juicy, honey! Oh shit, I'm gonna cum again all over your cock!"
Bill fucked savagely into the wet tightness of his mother's asshole, relishing the tightness of her puckered asshole as it throbbed repeatedly around his cock. He slid his hands around her delicately muscled back, wrapping his fingers around her big tits.
Lewdly he squeezed and milked the huge tits, catching the fat, inch long nipple between his fingers and pulling on the rubbery tips. Instantly Robyn felt the fuck-heat reaching a boiling point inside her, as her asshole spasmed and her nipples throbbed on his palms.
"I'm cumming, you fucker!" she cried. "Fuck my asshole, fuck my asshole! Unngghh, Bill, I love your big prick! Mom's cuming now! Mom can't help herself! Unh, Bill, cuuummmiiinnngggg!"
Her asshole spasmed and pulsed into orgasm, the narrow, rubbery tunnel clamping tightly around her boy's hammering cock. This time Bill didn't try to hold back his load. He collapsed on top of her blushing ass, spearing his throbbing cock as far into her asshole as it would go…
Even as she was cumming uncontrollably, Robyn felt the milky jism flooding into her ass. It spurted heavily into her aching asshole, spraying on the inner walls of her asshole. Bill humped steadily on top of her, draining his balls between her ass cheeks. Eagerly Robyn flexed her ass muscles, helping her son to shoot out all of his cum.
"Oh, Bill!" she whimpered. "Bill, oh God!"
Bill pulled his wet, fuck-wilted cock out of her asshole. Exhausted, Robyn slumped on the floor. She could feel the aftermath of the battering her son had given her in her asshole and pussy. She didn't think Bill had the endurance for anything else.
"Suck my cock, Mom," Bill said, rising to his feet above her. "Suck off the juice."
Bill grabbed her head and pulled her up into a kneeling position, her huge tits jiggling on his naked thighs. Robyn groaned as she found herself confronting the slippery, half-stiff shaft of his cock.
She was too tired to protest any more, too exhausted to resist anything her son had in mind. Bill pulled her hair and Robyn opened her mouth automatically. Bill pushed his cock between her lips.
The shaft and knob were coated with her ass juices and Robyn made a gurgling sound as she submissively clasped her lips around the shaft. Bill started humping his ass again. Robyn slut her eyes and thought of nothing but the big prick in her mouth.
She shamefully started sucking it, contracting her ass cheeks, wrapping her lips in a tight circle around the meaty tube of cock meat. Robyn made smacking sounds as she curled her tongue around the puffy knob of his prick, lapping the juices from the flesh of his prick.
"Suck it, Mom," Bill panted. "Ummm, what a good cock-sucker! You're making me cum again!"
Soon the cock was pawing again between her lips, swelling as hard as bone. I like doing this, Robyn thought dazedly. I'm sucking my own son's prick!
She shut her eyes more tightly, wanting to forget everything for the moment, to think of nothing but the big, stiff prick jammed down her throat. Robyn made loud slurping, smacking sounds as she sucked on it, chewing her lips on the shaft. Bill's prick continued to get stiffer, and then fresh pre-cum started to seep out of the piss-slit.
Robyn flicked her tongue on it, slurping it up. She wanted her son to cum now, wanted to taste the fresh spunk as it shot out of his balls. Hornily she wrapped her hand around the base of his prick, squeezing hard. She started jacking his prick as she sucked on it, bucking her head up and down over his cock.
"Ahhh, Mom!" Bill gasped. "Here it comes!"
The big prick throbbed violently, and then the white load geysered up from Bill's balls. It was just as big a cum as the first one had been. Long jets of creamy jism sprayed around the inside of Robyn's mouth, shooting across her tongue. Hornily the naked mother sucked it all up, drinking the load out of her son's squirting cock.
"Thanks, Mom!" Bill grinned and pushed her head away, reaching for his clothes. "See you at dinner, huh? Hey, I'll help you with the veggies some other time."
He left the kitchen. Robyn moaned as stray cum dripped from her mouth. Then she heaved a long sigh. It was time to make another phone call to Carla.
