Mike concentrated on his humping, fucking his cock furiously through his mother's slippery pussy tunnel. But at the same time, he found himself staring at her asshole.
It was hard not to stare at her asshole. Her ass cheeks were spread wide in the dog-fucking position and the pink little shitter was right under his nose.
Mike found himself fascinated by her asshole. He alternated between watching his own stiff cock, greasy with fuck oil, fucking into his mother's pussy and gazing at her tightly muscled asshole, seeing the way her asshole throbbed and puckered with every stroke into her pussy.
Mike slid one hand up, moving it into the sweat-slickened valley between her ass cheeks. He lightly probed his mother's asshole with his finger.
"Nunh!" Janet bucked and immediately started humping harder, feeling her asshole convulse around the probing digit. "Oooooh yes, Michael! That feels so good!"
Mike pushed his finger into his mother's ass. Her asshole was tiny and there seemed to be a ring of strong circular muscles around the very opening of her ass tunnel. He immediately felt them sucking around his finger, as if to tug it into her ass guts.
"Do you… do you want to fuck my asshole, Mike? Is that what you want now?"
Janet immediately felt herself gripped by an obscene desire for ass-fucking. The inexperience finger pushing into her asshole felt incredibly good and she was reminded of the depraved pleasure she'd once enjoyed with her husband.
"Take your cock out of my pussy, Michael!" she cried suddenly. "Run into the bathroom and get some Vaseline out of the medicine cabinet! Mommy's going to teach you how to fuck her horny butt!"
Mike withdrew hurriedly and climbed off the bed, retreating into the bathroom with his enormous prick throbbing stiff and wet before him. He returned a moment later bearing the big jar of Vaseline.
"Get it all over my asshole, Son!" Janet felt her shit tunnel throbbing lewdly as she anticipated the big prick fucking up her ass. "Then smear some all over your huge cock!"
Unscrewing the cap, Mike climbed onto the bed and crawled back into position between his mother's legs. He withdrew a think hunk of Vaseline and smeared it all over her asshole, making his mother groan as he darted his finger, covered with jelly into the rubbery ass tunnel.
Then he covered his cock from knob to base with Vaseline and dropped the jar on the bed. Holding his aching hard-on in his hand, Mike fitted the spongy cock knob against the pink wet circle of his mother's asshole.
"Yes, yes!" Janet spread her knees wide, dropping her hips low so that her son would be able to fuck his cock easily up her tight asshole. "Fuck me, lover! Go in easy! Fuck your big cock up my ass!"
With the tip of his prick embedded securely in her shitter, Mike hunched forward and held her ribs for support, his fingers touching the sides of her enormous swaying tits. Then he started to fuck his big cock slowly up her tight ass tube, feeling the Vaseline squish around his cock, between the prick shaft and her clinging ass walls.
"F-f-fuck meeee!" Janet stammered, groaning and shuddering as her asshole opened up to admit his cock. "Your dick is so fucking biiig! Fuck my asshole! Fuck your big prick up my ass!"
When Mike had fucked his mother's pussy, the whole slippery tunnel sucked and throbbed around his cock. He quickly learned that ass fucking felt different. Most of the muscles were in the ring around her shit opening. After he got through that, her asshole almost felt loose around his prick.
But the asshole muscles were very, very strong. Like a vise, they clamped around his cock, sucking every inch of the prick shaft as he fucked into her ass guts. Mike moaned as he fell flat on top of her, fucking his cock to the balls in the rubbery heat of her ass channel.
"Nnnngg! Oh Mike, Mike, oh fuck!"
Janet fell flat on her belly on the bed, squashing her huge, creamy tit melons on the sheets. She thrust her hand under her belly, gasping as she fucked two fingers deep inside her clinging cunt. Then she started to fingerfuck herself as her shit hole sucked convulsively around her son's huge prick.
"Fuck me, Michael! Fuck Mommy's horny asshole! Fuck me up the butt!"
Mike pulled out slowly, gasping as the strong ass ring clutched around his cock. He paused when the asshole muscles nipped at the very tip of his prick knob. Then he fucked his cock back in again, burying his prick to the balls between her jiggling ass cheeks.
"Nnnnggg!" Janet could feel her cock-stuffed asshole pressing into her pussy tube, separated only by a thin membrane. "Fuck me!" She started humping hard, knowing that she was already close to a good cum. "Unh unh unh, fuck my asshole! Fuck Mommy's ass haaard!"
Mike pulled out and fucked in again. Then he fell into a steady ass-fucking rhythm, fucking his bloated cum-packed cock steadily through the sucking heat of her asshole.
Her asshole muscles seemed to have a mind of their own. Convulsively they pressed and sucked his pumping cock, closing like a vise around whatever part of his prick was in her puckering asshole. It was a different pleasure than pussy fucking but just as good.
"Haaarder!" Janet flopped and humped madly off the bed, beside herself with incestuous pleasure as she rolled her clit under her thumb. Her asshole was throbbing hard, overwhelmed by the size and stiffness of the cock fucking into her ass guts. "Mommy's gonna cum, lover! Mommy's asshole's cumming all over sonny's huge prick!"
Moaning as his congested balls slapped her hairy pussy crack, Mike started fucking his mother's asshole as hard as he could. The bed creaked beneath them as they fucked wildly, groaning and writhing. Then Mike felt the jism boiling in his balls.
"I'm cumming, Mom!" he gasped. "I can't hold it! Oh fuck, oh Christ! Ahhh…"
He collapsed on her sweating back, fucking his prick all the way into her throbbing asshole. Janet squealed as hot cock juice erupted from his balls. Cum splattered deep inside her asshole, instantly filling the little shit tube with a big load.
"I'm cumming, Mike!" The cum splashed put the horny mother over the brink into ecstasy. "Unhhh! Keep fucking my asshole! Fuck Mommy's horny butt! Unnggghhh! I'm cummmmiiinnngggg!"
Her asshole spasmed uncontrollably, the tight ring of ass muscles squeezing almost painfully around her son's driving, cum squirting cock. Janet felt her whole body shudder as her pussy creamed, covering her fingers with fuck oil.
Tirelessly, she humped her ass onto her son's big prick, still horny, still ready for more fucking. But a blush of shame coursed into her cheeks at the same time. Janet knew that what she was doing was wrong. She couldn't keep on fucking her own son.
CHAPTER EIGHT
Janet paced nervously around the living room, occasionally pausing to rub her hand feverishly against her aching cunt. It was almost noon and she still hadn't dressed. Her bathrobe swished around her ankles, bulging out as the fabric stretched across her huge braless tits.
So horny, she thought anxiously. So fucking hot… Mike had gone off to school and Janet knew that she now had to rid herself of her obscene desire for his body. She just couldn't go on fucking her own child. She had to find another release for her lust.
Suddenly Janet remembered her sucking session with angela. It was hard to believe tha tit had only happened the day before. She'd liked it. Maybe she could learn to really like it a lot.
Biting her fingernails, Janet hurried across the living room and picked up the phone.
"Mmmmmmmm!"
Angela was sprawled naked on her bed, her huge tits jiggling as she fucked her fingers lazily into her hairy cunt. Unlike her neighbor, she didn't feel at all guilty for relishing the pleasures of her son's huge prick. She could hardly wait for Tony to come home so she could fuck him all over again.
Smearing saliva on her swollen cunt, Angela humped her ass, rolling her clit under her thumb. Then the ringing phone startled her from her fingerfucking reverie. Cursing, she went naked into the hall to pick it up.
