Joanne bobbed against the footstool, which might've scratched and dragged forward across the floor if not for her incredible mass anchoring it in place. Throwing her head back, the woman gripped the edge of the seat and ruthlessly fucked the pairing of her two favorite partners. After so much warm-up, Big Ben could impale her all the way to the hilt of the rubber sac at the suctioned base. This way, Joanne got up to speed in record time, giving off hideous groans of ecstasy as she humped, while the dildo slopped up and down her tract, creating a sound not unlike a wet cow's udder being violently milked. Within a couple minutes, the woman was screwing toward a barbaric quickie, having foregone technique and tantalizing strokes in favor of brute-force cunt-swabbing with the hard shaft of her trusty aid and the delightfully writhing shape of her child, whose presence was felt despite the rush. Flopping her ass cheeks against the stool's edge, Joanne achieved an explosive, gutturally-charged orgasm that nearly left her hoarse.

            Within, Tommy was treated to a grueling exercise in mind-breaking repulsion that made his prior visit to his mother's crotch while strung up in her panties seem like a soothing spa experience. At the height of her obscene euphoria, Joanne's nethers constricted as though performing muscle-clenching kegel training, which cramped her arousal-swollen tunnel around Big Ben and especially Tommy's frame so hard that the oozy walls, quivering and tensed like the haunches of a powerful animal, threatened to crunch the boy's ribcage inward if she flexed any more intensely. His cries for release, naturally, were only answered by forcibly guzzling another gloppy round of fresh-squeezed cum, though in a way he did get his wish, since Joanne's "release" at last brought on a heavy-breathing respite, then the sticky unpeeling of her clammy ass cheeks from the stool. Inch by inch the dildo slid out of her pussy's slippery grasp, stringing out long dollops of feminine nectar like liquid candle wax as it traveled, until finally the wobbly structure was freed from the pull of the canal, and Tommy along with it.

            The glue had faithfully kept Joanne's son rooted precisely where she'd planted him, and after she'd huffed through the hazy post-orgasm aftermath enough to peer down between her thighs at her partner, she was seemingly almost as delighted as she had been by that cheek-clapping climax to find he was right where she'd left him and, most importantly, still intact. Her joy was so effusive, swooning at the sight of her helpful lover-boy affixed in the perfect location at the stray-pube-decorated summit of good old Big Ben, she wasn't even grossed out to see her little love spewing up loads of her cum like the end of a drunken bender. Swinging her juicy rump back wrecking-ball-style, Joanne hunched down so her dribbling cunt lips just missed swallowing the toy again.

            "Oh, baby, I'm thinkin' it's time we change things up a little before the next round, huh?" she whispered, stroking her fingertips up the rubber shaft from suction base to Tommy's involuntarily fidgeting legs. Once she'd given her son a thorough fondle of gratitude, her fist closed around the heavily lubed pillar and ripped it from the stool with a pressurized pop.

            Joanne sauntered through the hall and up the stairs toward the master bedroom, letting her overly-supple hips dramatically sway with every step in order to give Tommy a show and keep him horny until the fun resumed, though this display was mostly lost on the boy while the dildo chaotically arced in his mother's grasp, swinging dizzily around until he almost had to puke for entirely different reasons than maternal cum-bingeing.

            In the bedroom, Joanne moved with a greater purpose, stomping across the floor so every piece of furniture quaked from her hammering footfalls. She went right for the bed, clumsily sifting her pear girth onto the sunken-in mattress, and drove Big Ben's faux-ballsack straight at the headboard. The impact instantly secured the suction cup to the center of the surface, while giving the glued-on lad a whiplash-inducing jerk not unlike if he'd crashed a car into a wall at fifty miles an hour. The hardened substance kept him cemented in place, however, which meant Tommy only had to contend with a neck ache on top of his pussy-bruised ribs, ejaculate-poisoned throat, and overall existential dread, plus whatever else his mother had in store for him now.

            The shrunken boy was suspended from the dildo's underside curve, though still with his face attentively pointed straight ahead, and made to witness Joanne inelegantly repositioning herself on the bed. Hunkered on all fours, she was clearly making an effort again to entice him with the slinkiest motions her blubbery assets could manage while also trying not to get tangled in the sheets or lose her balance on the creaky springboard of the mattress, an act she unknowingly failed at with several ass-jiggling near-stumbles. Eventually she'd turned her back on her toys both living and inanimate, though, granting Tommy a prime view to the twin moons of her cheeks. As her thighs spread wider, the dark crevice between them came into view as well, until no square inch of roomy flesh below Joanne's waist was hidden from her son's haunted eyes.

            Her gigantic buttocks took up so much of Tommy's view, he could hardly see the rest of his mother's immense body, though as she steadily tipped the hills of her backside higher, he could see her womanhood cresting into view from below, the curly forest marinating in her needful juices and plopping excess in a glimmering stream on the blankets below. Though the fur was naturally densest and darkest concentrated around her swollen slit, hairs dotted all the way to the edge of her ass-crack, while a couple raunchy strings were even sprouted in an uneven circle around her rectum. All while Joanne arched her back to fill her child's vision with her colossal privates and nothing else, she was also shuffling in reverse toward the backboard, causing the entire bed to rock like a galleon on pre-storm waves, until a sashay at just the right angle would bat Big Ben's cockhead, along with Tommy's actual head, over the dual cellulite curvatures. She'd aligned him perfectly in the center of her crack but, as Joanne's view past her own bottom-heavy hindquarters was limited, she'd aimed too high, and as a result, when she took one final nudge backward in hopes of teasing her son back through the soggy bush for another roll in the hay, the dildo and its prisoner were instead grazed across her dark tender anus.

            In response to the beguiling tickle of Tommy's face caressing the moist opening, her orifice fully unclenched as though to make way for its guest, and in Joanne's surprise, the first inch of the dildo, along with her son's top half, were immediately absorbed into her anal cavity without the slightest preamble of extra lube or smaller starter objects.

            Shocked and titillated, she let rip a shrill squeal nearly as hideous as her pre-orgasm mating calls then, in the same instant, expelled surprise air from the opposite end, blasting her boy with a minor but audible toot. As Tommy was chest-deep in his mother's asshole when the innocent fart was vocalized, however, the hot breeze blew back his hair and gassed him in oily pungent odor with strength horrifically in excess of the small accidental fart it actually was. As the slightest benefit, however, the force of the wind-break briefly at least reopened the backdoor entrance, which helped launch the dildo's tip back into the light, though Tommy's face was still made to brush the thin stray hairs around his parent's greedy anus and bask in its heat until she'd recovered from giggling.

            "Whoopsie. I believe I owe you a big excuse-me, don't I, honey-pie? Mommy's very sorry," Joanne throatily uttered, hardly conveying much remorse while she fought back more chuckles. "Hey, though, maybe this is just nature's way of pushin' us toward new frontiers. What do you think about a visit to a different kind of place, baby? You're already nice and slick for it. You felt how easy that was, didn't you? See, some women, and your ex-wife is probably one of them, talk about how going inside from that direction doesn't feel good, that it hurts, yada yada yada. Well, to them I say, you can't knock something until you try it enough to make it work, and let me tell you, sweetie, Mommy knows exactly how to make it work. Full disclosure, I am just a little gassy when I'm... shall we say backed up like I am now, but that won't be a problem, you have my word. You'll get used to it. See, that's something else other women just won't admit. Everybody's gotta stay regulated, and yes, that means a little toot from time to time. I know, what a shocker, us ladies are human too, no matter how pretty! But you won't judge me for that, baby, just like I don't judge you for any of your imperfections. Because in the end, those are the kinds of things that make us love each other even more, right? Here, let Mommy show you."

            Now with full intent, Joanne backed her plump cheek flanks into Big Ben, this time knowing precisely where to aim. With a twirl first around the rim that swiped those lone itchy anal hairs over Tommy's fluid-glazed shrunken features again, the giantess purposefully jutted her appetized portal at the thick head of her nine-inch tool. Unlike that first tempting bump, Joanne's anus didn't immediately reopen, allowing her to polish her son's face on the puckered flesh. The oppressive warmth steaming from her ass quickly melted the dried cum painted over Tommy's head, forcing him to keep spitting or suffer another grimy swallow all over again.

            "NO! MOM, STOP! DON'T... DO... THIS!" Tommy shrieked with everything he had, still delirious from the fact that he had to convince his own mother to stop swabbing his head around the puffy spigot of her asshole. This plea of course came at the cost of gulping another accidental cheekful of Joanne's syrupy cum, which he immediately coughed back up, along with a blob from earlier. His renewed tears soon drowned out the cries, though these were compassionately wiped away by his gigantic mother's fart-musky asshole.

            "Oy, darlin', it's like you're trying to kill the mood," Joanne grunted through gritted teeth. "I'll tell you now, since you're new to all this, tantrums are not the way to a girl's heart, especially when you're already knee-deep in the business. Lucky for you, your Mommy's the patient type, plus I've been waiting so long for this day, you could be doin' a lot worse and I'd still be able to finish, but in the future, I wanna see some commitment from you, young man. You've got real duties now, like it or leave it... well, in your case, you can't leave it, so you may as well start liking it. This might be the most important of your chores, too. See, Mommy's just not right if she can't rub off in the mornings, and lately, between you and me, it's not quite gettin' the job done to have to do it all myself. Things get a little dry after too much repetition, ya know? Well... maybe "dry" isn't the word I'm looking for, but the point is, I need you to help keep me regular. Getting that morning release is a lot like those dainty lady-toots I was talkin' about: you just gotta do it, and if you don't, all sorts of things can go wrong. The same goes for you too, of course. Mommy won't have you just keeping it all pent up. So. How're we doin' down there, baby?"
