Chapter 3

John stood stock still in the middle of the room smiling vacantly at Kate. He impulsively pulled at his swollen dick through his sweatpants, struggling to work out how to get inside them. His newly reduced intellect didn’t allow him to consider why he might stop. It just felt great to stroke his big dick.

“I wanna get my dick inside you!” he repeated, more forcefully this time, then let out a low, grunting laugh. He was delighted with the statement he had made and the fact that his hands had finally made it past his waistband. 

Kate smiled and chuckled. “Well aren’t you sweet Johnny!” she cooed at him. She still had one arm wrapped around Jack’s shoulder and the other rubbing his intensely hard dick. “Sorry baby, I think Daddy might need some help.”

By now, John had tugged his sweatpants down to his knees and was openly working his massive weapon proudly in front to them both, groaning. “Yeah.” he blurted out thuggishly, “you can watch me fuck your mom.” giving a low, slow laugh. John’s delight at thinking of this was obvious, as was Kate’s.

“Wanna see Mommy take Daddy’s huge dick Jacky?” she cooed. Jack was still amazed at what a pair of closet perverts his parents clearly were. He also realised he’d inherited this trait.

John grabbed his wife’s hips and bent her over the table next to Jack. She shrieked and giggled with delight as he took on the challenge of getting her tight shorts down. With no ceremony at all he penetrated her. She let out a moan, her eyes rolling back into her head at the pleasure. She was, by now, utterly desperate for sex despite it only being an hour or so since her last session. John started plugging away at her, loving the way her warm hole gripped his fat cock. He looked across at Jack who was drinking in every moment. John had fantasised about sharing his wife with Jack many times. He couldn’t understand why they hadn’t actually done it yet.

Kate also looked up at Jack, her face a picture of ecstasy. Turning her son on like this had got her so wet. Like her husband, she couldn’t figure out why she’d never fucked or played with him before. The way his eyes were locked on her getting fucked and the big tent in his sweatpants was arousing on even more.

Between moans Kate managed to blurt out “Aren’t you gonna show mommy how hard she’s got you?” She shifted her body and used one of her hands to work her tiny top up further to exposer her big tits properly for him. “Maybe you could put it between these,” she jiggled her hanging tits side to side for emphasis, “or in mom’s mouth?”

This made Jack’s dad groan, just the thought was almost too much for him. “Yeah, fuck your mom’s face” was all he could manage as he jetted another surge of spunk deep inside Kate triggering her into another boundless orgasm.

Jack was in a slight quandary. He was loving watching the show and his parents’ unfiltered urges coming to the fore. He also couldn’t think of anything he wanted more than to get involved. But, he was somewhat intimidated by his father’s size and didn’t want them to be disappointed, despite, in real terms, being reasonably well endowed. He was considering using the app on himself, but needed to take care not to get into the same mess as his father. This thought was reinforced as his dad slid his still leaking cock out of his mom’s pussy and wiped it on the sofa next to him whilst working it up for yet another round.

Meanwhile, his mom flipped over and sat up on the table, she wriggled round, her legs spread wide as she played with her cum-dripping slit. “Look at how full I am!” She quivered as a little ripple of pleasure surged through her. “Do you think you might have some hot spunk for mommy?”

That clinched it, Jack quickly navigated to his own page on the app and slid the cock size slider a way up. He felt the tightening of his sweatpants as his loins swelled in response to the app, it was unbelievable. Noticing the movement around his crotch his mom let out a little sigh, “Looks like there’s a naughty boy in here who wants to play with his mommy!” she giggled, sliding her finger more rapidly in and out of herself.

John was getting impatient. His cock was pulsing again and he really wanted some more action. “Hey Kate, can we fuck some more now?” he asked bluntly.

She smiled over at him loving the look of his massive shiny cock head already oozing as he wanked himself. “Awww, honey, I love that I’ve got you all hard again, but I’d really like to be a bad mommy with Jack right now.” she chirped.

John moaned, the idea of his son and wife fucking was a fantasy he’d imagined for so long.

“Why not keep jerking your big dick and let us get started, then maybe I could suck you as Jack fucks me?”

This sounded reasonable to John, he couldn’t wait to see this and was even more excited about getting his needy cock sucked. “Go on son, give mom a good hard fuck” he blurted out, chuckling to himself as he worked his long thick shaft with both hands. He was almost ready to explode again.

Jack used this distraction to just nudge his own desire up a little, keen not to disappoint his mother. But he needn’t have worried. As he lowered his pants, exposing himself to his parents for the first time in many years, Kate let out a long gasp of excitement. “Ooooh, mommy’s big boy!” she giggled again, “I’ve got just the place for that!” She held herself open for him staring with desire at his big dick. Although Jack hadn’t pumped himself up as much as his father, he now had a member that would make most pornstars jealous.

“Has daddy’s cum lubed me up nicely for you?” Kate moaned as he eased into her. Jack’s body took over and he was soon thrusting his entire length in and out, making Kate scream with excitement. The sight of his son pounding his wife was intense, John had jerked off imagining this happening before. He groaned as a thick glob of pre-cum oozed out of his dick and ran down the shaft.

He didn’t possess the mental faculties to control himself any longer, moved back towards his ecstatic wife and rammed his throbbing meat into her mouth. Kate let out a muffled squeal of joy, loving the feeling of her husband and son pounding her from both ends, her dirtiest fantasies being realised. John and Jack both mauled at Kate’s massive bouncing tits as they both passed the point of no return, locking eyes as they both shot rivers of spunk into her. Kate gurgled on the phenomenal load her husband dumped in her mouth, hitting another orgasm as she realised she’d made both her boys cum so fast.

The rest of that afternoon was spent fucking, the father and son team swapping ends and changing positions regularly. After they shot a final simultaneous load all over Kate’s face thanks to a skilfully administered double blow job, Jack realised he was spent and collapsed on a mostly clean section of the sofa. His parents continued their activity for a while longer, frequently checking he was watching them and eagerly encouraging him to join in again. By the early evening all three of them were spent for the time being.

Over the next few days Jack enjoyed what was basically a free-use regime with his parents. His mom was always up for a bit of fun with him, or more than willing to put on a show with, or without his dad present. He was still fascinated by the underlying desires he seemed to have unlocked. His mother’s attention seeking and desire to be an object of lust and their kinks for family fun.

He kept trying to find time to explore the app and try to decipher its codes and abilities. He knew it would be a good way to to find out more about his parents little perversions. But he hadn’t managed to do this yet, the distractions were always far too strong or he was just to tired out.

He found that keeping them both in a dumbed down state meant they didn’t really consider going out of the house. Just putting the door on the latch made it too challenging for them to operate anyway. They were also quite easily distracted by him leaving porn playing on any screens around the house so he had become quite complacent. However, an incident on the third day made him review this stance.

They had all been getting some rest after a morning spent DPing his mom to a state of utter ecstasy. Jack was fixing them all some food and was under the impression that his parents were asleep. Kate, however, had been having trouble sleeping and was actually still pretty horny. She’d slipped upstairs and helped herself to the biggest vibrator from the drawer by her daughter’s bed. Then she slumped on one of the arm chairs in the living room and started pleasuring herself with it in time with the hardcore action on the screen. She imagined herself starring in a movie like this and guys all over the world jerking off to her.

Meanwhile, a delivery van had pulled up outside the house and one of the guys had come to the door, first checking through the front window to see if anyone was in. He was nearly knocked over by the sight inside and stood, fixed in position, staring in. It hadn’t taken long for Kate to realise she had a real audience which thrilled her further. She smiled at the tall, fair haired guy at the window, turning her body to give him a clear view of her leaking pussy and she sank the full length of the toy deep into herself. With her other hand, she squeezed one of her inflated tits and pinched her nipple biting her bottom lip and fixing the stranger’s gaze.

Meanwhile, the guy had snapped out of his trance long enough to signal to his mate in the van to join him. Kate cooed with delight as the stockier, muscular colleague appeared at the window. He was equally surprised at what he was seeing. Both men watched Kate perform for a few minutes before one of them tried to signal to her to let them in. She was completely incapable of working out what he was doing, but she knew she needed to fuck them both quite urgently.

After a few minutes, she realised that the men kept pointing at the front door. She discarded the still buzzing vibrator on the floor and strutted across the room. The way the two men’s eyes followed her turned her on even more. Kate had found that the door had become so complex recently. But after a few seconds of her desperately rattling at it, it somehow swung open and she was confronted by the two shocked and obviously rock hard delivery men. Kate grabbed the two guys, pulling them over the threshold, then sunk to her knees tearing at their bulging uniforms to free their cocks.

This was when Jack had noticed something was going on. Coming around the corner from the kitchen, he was confronted by his mother frantically sucking and jerking two strange men wearing the remains of their delivery company uniforms. Both of them were completely lost in the favourite pornographic fantasy of their profession. Individually, they had wondered if this was some sort of prank and whether there might be hidden cameras, but this opportunity was just too good to miss.

As he overcame his initial shock, Jack stayed just out of sight enjoying the scene. The two guys were very different, one was darker skinned and clearly worked out regularly, the other tall and thin with an already sizeable dick. Jack realised that the app had registered these two new subjects and he was unable to resist making a few adjustments.

As Kate deep throated the whole length of the tall guy’s cock, Jack carefully timed his adjustments so that as it emerged from her mouth, it was an even thicker, 13’’ monster, like some sort of perverted magic trick. Kate smiled as she saw it, delighted at what she had done and jammed the entire length back down her throat, in some way hoping she could make it even bigger. He repeated this trick with the other guy, who seemed in equal measure delighted, horny and scared by what was going on. His colleague was too absorbed in the moment to really take it all in.

Jack gave both guys a ‘desire’ boost that seemed to erase the more built guy’s doubts. He held Kate’s head and started fucking her mouth with determination. Kate let out a series of muffled giggles and ‘aaahhhs’, looking up at him letting a line of precum and drool slide out of her used mouth.

His colleague moved around Kate, pulling her to her feet and propping her on the low hall table to give himself a clear shot at her sopping pussy. He slammed himself deep inside her making her howl with pleasure, though she never let go of the cock currently using her mouth. It was a matter of minutes before all three were cumming loudly, the guys filling Kate at both ends before sliding out and swapping for the next round. After another messy orgasm each, the built guy sat himself on the hall table letting Kate straddle him facing forward. This gave the taller man a change to push into her at the same time sending Kate into a wave of foul mouthed ecstatic screams.

After the guys had both filled Kate for the third time, Jack decided that he really shouldn’t risk anything more. He hadn’t even considered that the door was still wide open or that he had no idea what his dad was doing. He dialled the guy’s desire levels back down again and their still enormous appendages drooped in front of them, a mixture of fluids dripping off them both onto the floor. Kate initially made an effort to get them back up again, and looked almost hurt that they weren’t hard for her any more. As Jack brought her down to earth, she quickly lost interest, wandering unsteadily back into the house for a rest.

Regaining their sensibilities again, the delivery men quickly pulled their pants back on, tucked their expanded members away and almost ran back to their van. Both had rising worries about what had happened and for the first time the taller man thought about whether his girlfriend would ever find out. Jack decided to leave both men impressively endowed and set their desire levels back up a little before they drove off out of range. He saw this increased sexual stamina as a gift for any of their future partners. Jack observed their concerned expressions turn to more gleeful, animated discussions of the events of the last hour. They blew their horn at a group of four young women walking up the street. They leered obscenely from the window of the van as they passed, imagining a session with this group, their new equipment starting to stir once again.

Jack settled his Mom back down in the living room, pulling the blinds and shutting the door, hoping that this wouldn’t lead to any consequences. Kate still insisted on jerking him off over her face and tits saying that it was, “Mommy’s fault that her boy’s all hard.” before she fell asleep. This gave Jack a bit more time and a clearer head to clear up and finish making the food.

John woke a little later feeling rested and so fucking horny. His huge cock stood proudly in front of him, hard as an iron rod. He was struggling to recall why he was so huge now because he was sure he hadn’t always been like this, but he loved it. He also loved how good it felt when he wrapped his hands around the thick shaft and worked it. Before he got too carried away he wondered if Kate was around as it was even better when she went to town on him.

He slid out of bed, and headed down to the living room, eagerly rubbing himself as he walked. He found Kate, naked, unconscious and sprawled in one of the arm chairs. She looked amazing and her huge tits still glistened with a mixture of Jack and the two delivery men’s cum. John straddled her and pushed her big tits together around his member. Again, he didn’t remember Kate having tits quite this magnificent before, but he wasn’t going to complain. The huge warm pillowy mounds pressed against his sensitive dick in just the right way and he let out low groans as he started easing himself in and out of the tight crevice he’d made between them.

When Jack walked in from the kitchen with food, he found his Dad aggressively pounding into his mom’s tits, on the brink of cumming. John was enthusiastically groping Kate’s large, erect nipples as he used her boobs. His newly awakened mother was giggling with delight and encouraging him, “Come on Daddy, give Mom that big load.” As his swollen cock head emerged just below her chin, she attempted to lick or kiss it, taking him ever closer to the edge. A couple more thrusts and his dad went silent before groaning loudly as he caked her face and cleavage with another flood of spunk. Kate made a show of lapping it up, looking straight up at him with a sultry stare.

Jack had put the food down on the dining room table and, keen that they eat something, took his chance to dial down their “desire” a little before calling them. As his mom passed him, she wrapped her arms around him and placed a deep, cummy kiss on his lips telling him how good he was to look after them. Both parents threw themselves into eating with the same enthusiasm they had put into fucking over the last couple of days.

Sitting opposite his Mom, it wasn’t long before Jack felt her foot in his crotch. She caught his eye, tittering, then attempted to seductively lick the food off her fork. Kate tried in vain to coordinate her movement and it ended up more cutely comical than erotic. Jack’s dad meanwhile, was stuffing food into his mouth like a hungry animal, grunting with satisfaction as his swallowed it down. It didn’t take long for Jack to realise that his Mom’s free hand had worked its way into his father’s crotch.

Jack checked the app, it was amazing that his Mom was still this aroused with her “desire” levels only set at 150%. He guessed she was just a very horny person.

Having eaten all she wanted, Kate decided there was another hunger she wanted to feed. She slid under the table onto the floor and crawled to her husband’s large, semi-hard phallus. She licked along the length of it, then puckered her lips around the tip, making little suction noises as she kissed it. It twitched, but didn’t really respond despite Kate’s best efforts. John was still engrossed in eating and although the feeling in his dick was pleasant, his need for food was more pressing.

Saddened, Kate redirected her mission to her son’s crotch, making him jump and she playfully sank her teeth into the giant bulge in his pants, making growling noises. She was thrilled when the bulge throbbed in response showing her a clear outline of his massive sausage straining the fabric along the front of his pants.

Although Jack wasn’t really in need of a blowjob right now, the fact it was keeping his insatiable mother occupied was a good thing. He activated his Dad’s phone and slid his own desire up a bit enabling him keep up with Kate’s need a bit better.

Seeing Jack doing this made his father laugh. Through a mouthful of food he said, “Phone fun!” drawing on a distant memory that his phone led to good things.

Kate had managed to hook her fingers into Jack’s waistband and ease his sweats over his spring-loaded cock. She squeaked as it jumped free and enthusiastically set to work licking it from base to tip.

Jack was just finishing his last few mouthfuls when his own phone rang. He turned it over to see “Lucy”, his sister’s name, flash on the screen. Jack felt he really ought to answer this. He knew his sister wouldn’t have heard from any of them since the start of this adventure and might be getting concerned. He looked down at his Mom asking her to ease off a bit. She fixed his gaze, nodding and making a little “hmmm” sound of approval, then continued wither work on his dick with exactly the same ferocity.

Jack took a deep breath composing himself. “Keep this short,” he said out-loud to himself, “I can do this!”

Jack opened the phone and, as casually as he could, said, “Hi Luce, how’s things?”

“Thank fuck,” was his sister’s immediate reply, “are your phones broken? I’ve tried to get Mom and you so many times. Is everything OK?”

“All good here,” Jack responded, trying to stifle a moan as his mom sank his length deep into her mouth. “Sorry, I’m just eating.”

“Bullshit, what’s going on? Where’s Mom?” His ever astute sister saw straight through his pretence. Lying to her had always been impossible.

“She’s right here and she’s fine.” He stammered, looking down, he saw him Mom panting slightly with her mouth wide around him, her tongue out a little, cushioning the underside of his cock. She stared up at him wildly.

“Can I speak to her?” asked Lucy.

“She’s…. mmm… kinda busy right now… ahhhh.” Jack responded, leaning down to push his mother back off his cock a little. There was no way Kate was having that. She pushed back against him driving his cock deeper in, gurgling and choking a little as she did it.

“Is that her? What the fuck is going on? You need to tell me right now! I’m coming over tomorrow, so I’m going to find out anyway.” Lucy wasn’t shouting, just resolute.

Jack sighed; he knew that he wouldn’t be able to cover this up, so he’d best clue his sister in on at least some of the events. They had a really close relationship and had shared some pretty intimate thoughts and experiences over the years. Jack closed his eyes, drawing his thoughts together and went for it.

“It looks like Dad’s put something on his phone and used it to fuck with them both.” He felt quite pleased with the diplomatic way he’d put that, omitting some quite significant incriminating details.

“Fuck with them? In what way?” Lucy asked, a knowingness in her voice.

“It looks like he got some sort of app, and don’t ask me how, he’s used to alter them both physically and mentally. Now they’re both weird.” Jack carefully skirted around his own involvement on all this.

Calmly Lucy replied, “Is it that control sex app thing?”

“What’s that?” Jack asked in fake naivety. Of course Lucy would have heard of it, a total geek about all things fringe tech!

“It is isn’t it? I’ve seen forums about this online.” Her excitement was now tangible. From the moment she’d seen something about it, she’d been desperate to see it at work. She also couldn’t deny that the idea of it having been used by and on her parents was also giving her quite a thrill. “Make no changes, I want to see exactly what that pair of perverts have been up to!” she demanded. Then, with a wry laugh added, “or should that be a trio of perverts?”

Jack reflexively cleared his throat in response. The intensifying pleasure rippling through him from his Mom’s activities made it impossible to give a coherent verbal answer.

Before he got his thoughts together Lucy added, “See you tomorrow, about midday. Love you, you dirty little fucker!” and hung up.

Jack sighed and thought about the work ahead of him. At least there was no requirement for him to change his parent’s back before Lucy’s arrival, but organising the house and keeping them under control was going to be a challenge.

He pulled his chair back, finally relieving his mother of his dick. “Right you two, we’ve got some important stuff to do!” he shouted.

His dad looked at him with an uncomprehending expression across his food-splattered face. Kate emerged from under the table, bouncing to her feet, tits wobbling uncontrollably. She presented herself to her audience with her arms outstretched like some kind of triumphant gymnast. “But first, Katy needs to get fucked some more!” she announced with glee, her eyes darting between the two men.

To be continued…
