Appy Family

Chapter 4

Jack opened up the app on his Dad's phone once more. He flipped it to his Mum's profile and checked her stats. As he suspected, her "desire" level had risen of its own accord and she was now well above 200%.

As he looked up, Kate caught his eye, giggled, then licked her lips seductively and made a show of pushing her fingers gratuitously between her legs. "Doncha wanna fill Mummy up again?" she purred then let out a long moan as her digits made contact with the right spot.

Jack realised that with his parents in this state, they would need to get to work if they were going to get the place a little tidier before his sister arrived tomorrow. Before that, they would probably need to try to fulfil his Mother's seemingly insatiable needs.

Of course, dialling her desire down was an option, but it didn't seem to stay down for long. Plus, where was the fun in that?

He decided to risk giving himself a little desire boost so that he could keep up with his overtly horny parents. His swelling cock instantly drew Kate's attention and she strutted up to him, hips swaying.

"Looks like he's more than ready!" Kate chirped with delight. She turned and backed up against her son, wantonly grinding her butt against his erection.

Jack's knees weakened a little and he stumbled backwards into the lounge chair behind him. Kate fell back onto him, laughing. Suddenly, she fell silent, then looked back at Jack.

"Ooooh, Jacky wants to try that hole does he?" she teased, smiling broadly. Using the chair arms for support, she lifted herself slightly and manoeuvred herself into position.

Jack couldn't believe the ease with which she took him into her arsehole. The tightness was heaven on his aching dick. Kate was also having a revelation. She'd tried butt stuff with her husband and with boyfriends before that, but never remembered it being this good.

The thought of letting other guys use her arse made her shake with pleasure. She started rocking her hips and releasing a set of pornographic noises. At one point Jack heard her utter, "Mmm, feels so good in Mummy's butt!"

This action had peaked John's interest. The sight of his wife impaling herself anally on their son's cock was sending a tingle through him. He left his place at the table and stood over his wife, uncouthly grabbing a handful of one of her inflated tits in one hand.

Through the blissful haze, the sight of his Neanderthal-level Dad getting worked up reminded Jack that he could help things along here. He still had the phone in his hand and with some concentration managed to open his Dad's profile. He pushed his thumb onto the "desire" slider, just as his mother clenched his cock tightly in a pre-orgasmic spasm.

Jack managed to give his Dad the boost he aimed for. His giant vieny dick rose instantly to full attention making Kate squeal with delight. "Do it babe!" she demanded over and over.

The phone slipped from Jack's hand and it landed just out of his reach. However, he could see that the long press he'd accidentally given the screen before dropping it had opened up a whole load of new menus. With his mother writhing around on his cock, Jack was in no position to find out if he'd changed any of these new settings.

"For fucks sake Dad, she wants you to fuck her too!" Jack shouted, snapping John out of his titnosis trance. He grunted with realisation and slowly moved into position.

"Fuck yes, I want both my boys in me.... Stretch my holes.... Fill me up..." Kate screamed, watching as her husband forced his wide throbbing pole into her cunt. This was beyond anything she'd felt before and her first orgasm hit instantly.

John had only just got started, pumping his dick in and out of his wife like a machine. Kate, still cumming hard, was shaking uncontrollably, clamping Jack like a vice. Jack knew he wasn't going to be able to last much longer either.

John, between grunts of pleasure, chuckled. "Kate's such a fuck slut!" he droned, loving the way his wife had demanded he and his son use her. It was a dream come true and he could feel the surge of another orgasm building.

Even in his weakened mental state, John could tell that something was different. The pressure building was more than he had ever known before.

Kate was still rapturous, her arousal boosted again by her husband's comment. She was babbling on, almost incomprehensibly, about being a "fuck slut", a continuous orgasm rolling over and over her. She rammed herself down onto her son's twitching rod, gasping as she felt the first blast of cum shoot deep into her butt.

"Oh Jacky, has Mummy's butthole made you cum" she teased looking back over her shoulder at her son's screwed-up face, his own climax in full swing.

Kate was unable to stop sliding up and down on Jack's cock due to the vigorous pounding she was taking from her husband. Mum and Son were both wrapped up in unimaginable levels of pleasure.

All of a sudden this spell was broken, and they were both alerted to John's moaning turning to urgent strained shouts of, "oh fuck!... oh fuck! gonna cum!... cum hard!...nnnng".

Kate felt her John's arms and legs weaken slightly as he started shooting up her. His first jet of cum seemed to plaster her whole insides with the force of a jet hose. She felt the spunk oozing out of her around her husband's corpulent pulsing cock. She shoved him back, partly because she feared she might burst but mainly because she wanted to see what was going on.

With his strength redirected to power his fierce ejacultion, John was unable to resist his wife's push. He stepped back, his giant member springing out of her and immediately sending three massive super-powered streams of cum over her face, tits and belly.

Almost drowning, Kate gasped for breath through the torrent of fluid, shocked but hopelessly aroused by it all.

Jack had made a guess at what was coming and had drawn himself in under his mother, her body shielding him from the deluge. After what seemed like hours of shrieking and groaning, Jack heard a thump. He guessed it was his Dad falling over and dared to peek out from under his Mum.

His Dad was sitting on the floor, legs slightly spread, looking around, bemused. His distended cock still upright and visibly throbbing, secreting smaller jets of spunk with a reasonable force.

Kate sensed her Son's movement and turned back to him. Her caked face was a vision of joy, "Look at how much cum I got out of Daddy!" she chirped triumphantly, licking some of the gooey mess from around her mouth, "Has Jacky got any more for me?"

Jack realised that he definitely had. His cock was still rock solid thanks to the boost from the app and the firm grip of his mother's butthole. She started riding him more rhythmically, working herself up again.

The two of them engaged in another round of frantic love making. All the while John sat, enjoying the show. He still lacked the energy to join in, but was unable to resist trying to stroke himself fully hard again.

As the session ended and another climax waned, Jack regained some clarity and pushed his Mum off him. She started proudly strutting around, posing and theatrically licking up cum from her big tits, or using her fingers to dip it out of her holes.

Jack had picked up his Dad's phone and was examining what he'd done earlier. The subfolder he'd inadvertently opened with his long press had another set of sliders all labelled with more indecipherable characters. The whole set were controlled by the main "desire" level slider, but this menu opened the opportunity to alter more specific aspects of this area.

Two sliders were pushed way up, and he concluded that these were the ones relating to the fact his Dad had become a human cum fountain. Fearing he might be heading for a repeat performance, Jack pushed these back down to match the other sliders.

His Dad continued wanking, merrily watching Kate parading playfully around and dancing for him. The sliders clearly made no difference to his keenness to get off. Hopefully this time though, he wouldn't create another lake of spunk like the one he was currently sat in.

"Shit!" Jack said out loud, the memory that things needed to be cleaned up ready for his sister's arrival tomorrow re-entering his head, "We've got some work to do you two!"

Barely turning to him, his Mum straddled his Dad where he sat and lowered herself down towards his big dick. "Awww baby, no work," she pleaded, "we just need to fuck some more." With that she was on him, riding him as he sucked enthusiastically on the tits he'd sprayed so spectacularly minutes before.

Jack let them get on with it, figuring that if he allowed them a few more orgasms, their desire levels might be easier to control. He used the phone to wind his own desire back and immediately felt the weight of his own sexual exhaustion. Then he sat scrolling through the various new settings in hope of finding some way to make his parents more helpful.

Jack opened the sub-categories on both of his parents' "Head" sliders.

Fiddling around with the incomprehensible settings, some had no obvious effects. However, others gave a whole range of emotional changes, from hysterical laugher to inconsolable sobbing to vocal anger. At no point did his parents relent from their fuck session on the floor.

His Mother, in an extreme bout of temper, demanding that his sobbing Dad, "use that fucking horse cock of yours to make me cum again you cunt!" was something that Jack found surprisingly arousing.

After a while, it dawned on Jack, that his Dad was compulsively fulfilling every demand his still rage-fucking mother made. He wasn't sure whether this was just because his Dad was unable to rationalise his own course of action, so he tried saying, "Hey Dad, pull out of Mum and go stand in the corner".

Immediately, and to Kate's disgust, John stopped bucking his hips and started trying to lift her off him. Before he got too far, Kate issued a counter command, "What the fuck! Get your cock back up me right now!" and he immediately complied.

Jack was pretty sure he'd found the right control to get the jobs he needed done. He let them get each another to climax again and then took the opportunity to boost this "compliance" setting for them both.

"Get up and stand next to each other!" Jack commanded experimentally. Reluctantly, his parents tore themselves apart and stood side by side, his Mum glancing between Jack and John's cocks, spunk still dripping from her face and tits.

"But I want some more cock!" Kate giggled with frustration, reaching out to grab her husband's still ridged dick.

Jack couldn't help but feel aroused at this, even though he'd attempted to tame his own "desire".

"Put your hands on your heads!" Jack tried, both parents complied hesitantly, their attention still wandering to each other's bodies. Their eye's met and they exchanged a dim laugh, Jack saw his Dad's cock visibly responding to the sight of his partner.

Keeping her hands in position, Jack watched Kate lower herself to her knees in front of her husband's member and lick the tip, her arousal overriding her compliance somewhat. Jack realised that even with this new feature, he still wasn't going to have an easy ride. He again considered dialling their arousal right down and maybe even bringing back some of their intelligence, but seeing them in this state was too much fun.

"Stop now Mum and stand again." he instructed firmly. Kate pouted and withdrew back to her standing position, hands still elevated. His Dad grunted in disappointment.

Looking at the clock, Jack realised how late it had got. He just couldn't entertain the idea of performing a clean-up job now. "You need to go get some sleep ready for tomorrow." Jack continued, and with her hands still elevated, his Mother trotted playfully up the stairs, enjoying how the gaze of the two men followed her.

"You go get some rest too, use the couch." Jack instructed his father after his mother had stopped moving about upstairs. He didn't want to risk them getting too much close contact. His Dad stumped off across the room, instinctively stroking his boner as he went.

Once his Father was settled, Jack opened the phone, browsing through the menus again looking for something that actually made sense, but frustratingly found nothing coherent. His attention was brought back into the room by the loud snoring coming from his father, who was slumped across the couch fast asleep, still holding his giant dick firmly in his hand.

Jack sneaked upstairs hoping that exhaustion had also settled in for his Mum. He was delighted to find her, also unconscious, on his sister's bed. One of his sister's vibrators was rumbling away still embedded in her pussy.

Fearing that in this state, his Mother could injure herself, Jack tip-toed into the room. He reached down to de-activate and remove the sex toy. As he slid the long rubber dick out of her, Kate stirred slightly, moaning, "oh Jacky, fuck Mummy and Lucy some more!"

Jack chuckled with relief as she went back into a deep sleep and, keen to get some rest himself, crept back to his own bed.
