Chapter 2

John lay in a blissful post-orgasmic sleep, his big glossy dick a mess of his own cum and Kate’s juice and saliva. Try as she might, Kate could find no way of reviving him. Disappointed and still horny as fuck, Kate rolled onto her back next to him rubbing her needy clit and letting the waves of pleasure float over her. She noticed the light of John’s phone screen on the floor and thought that it might be fun to see if she could find some porn or maybe she could even try to film herself and post it online for everyone to see. She slid out of bed and pulled on a robe, her sweaty body was really feeling the chill of the night. The she picked up the phone and headed down to the lounge to see if she would work out how to make her movie. She got comfy on the sofa, her free hand still stimulating her slick pussy and looked down at the phone screen.  

The sight of the giant dick filling the screen made her cunt twitch and she redoubled her rubbing letting out little moans as she studied it. At the top of the screen she saw some writing which she found quite hard to read. However, she recognised John’s name and even in her weakened cognitive state realised that the image must be of John’s cock. She balanced the phone on her leg and messed with the sliders, there was no way her other hand was leaving her pussy alone. She noticed that one made the giant dick even bigger which excited her further, sending the quiver of a mini orgasm through her. The other one didn’t seem to do anything even when she nudged it up quite a lot.

Then she spotted her own name and some tits in a little inset windows at the bottom of the screen. Clicking on this swapped the image over and she giggled at the sight of her big round tits. She was reminded that she had meant to make a hot movie of herself, but was having way too much fun at the moment. She moved the main slider by her breasts up and giggled as the image expanded, then gasped knocking the phone to the floor as she realised her own tits had swelled up even more, pushing the robe open letting the cold air touch her oversensitive nipples.

Kate bounced with joy, feeling like she’d solved a hugely complex puzzle as she realised the link between the phone app and her own body. Then from there, she also worked out that she might well have done the same to her husband’s cock. This all had her getting close to another orgasm, but she needed to see this to check. She stood to rush upstairs almost walking squarely into her son, Jack, who had just returned from his night out.

“Ooooh sorry Mom, I didn’t realise you’d still be up,” he said.

“Hi Jacky!” Kate giggled seeing his eye’s fall to her semi exposed tits and her hand still wedged between her legs. Kate was so aroused by this, and impulsively wanted to take it further, thrusting her tits out a little more for him and letting the robe hang open further. However she was also very excited to see if she was right about the changes she’d made to John. “Sorry, I need to go up and have a look at daddy’s cock.” She blurted out before rushing out of the room and heading upstairs.

Jack was left in a daze. He couldn’t quite piece everything together. Firstly, there was his mom’s state of dress. He’d seen her naked, but not for a long while, and also in fairly flimsy and revealing clothes thanks to his sister’s fashion advice. But there was something different about her. She had amazing tits, he’d studied them a lot and his horny teenaged brain had often incorporated them into his fantasies, but he was sure they hadn’t been anywhere near this big and she didn’t usually expose them like this. Then there was her behaviour, she never called him “Jacky” and she had obviously been masturbating when he came in. Maybe she was panicked by being disturbed. Then he noticed the phone lying on the floor, screen still lit up.

Kate reached the top of the stairs. A strong part of her wanted to go back down and play with Jack, but her need to see whether she had adjusted her husband’s cock was even stronger. She pushed open the bedroom door and there was John, still asleep on his back as she’d left him. However, his now gargantuan dick stood proudly to attention throbbing and oozing pre-cum thanks to the “desire” boost Kate had ignorantly given him.

It was like the trunk of a small tree and Kate was delighted, throwing herself onto the bed and taking Johns massive reinvigorated member in both hands. She couldn’t get one hand around the shaft and although she was reluctant to relinquish the pleasure she was giving herself, she needed both hands to fully appreciate this beauty. It was so thick, veiny and warm, gently throbbing like it was ready to go off any second. She leant in and ran her tongue from the base the full 15 or so inches to the leaking head, giggling to herself.

John was brought back to consciousness with a surge of pleasure ripping through him like nothing he’d ever experienced before. He let out a loud shout of “fuuuck,” much to his wife’s amusement. He opened his eyes to be greeted with the sight of his enhanced wife seductively trying to fit her mouth around the head of his gigantic penis. This only made him hornier. His desire to get off was completely overwhelming and he growled, “Yeah, suck me bitch,” before reaching down and forcefully but lovingly pushing his wife’s face down onto his swollen gland.

Kate had never known her husband to be quite this forward. But it was so exciting to her. She stretched her lips over his insistent cock and let him sink it in as far as possible, then matched the involuntary thrusting off his hips, working her head up and down. John was grunting and cursing loudly at every movement and Kate was delighted to be doing suck a good job. With the hand that wasn’t on her head he reached down, enjoying mauling her big tits and squeezing her nipples. She had returned one of her hands to its rightful place between her legs. Neither of them was going to last long.

Jack meanwhile had picked up his father’s phone from the floor and had already kind-of fathomed out what the open app was about. He still currently assumed it was some kind of fantasy or game play, although it did seem to tie in with how strange his mother had seemed. It was then that his attention was drawn by the loud grunting and giggling from upstairs. Jack had regularly enjoyed listening in on his parents having sex, they weren’t exactly quiet under normal conditions. But this was again different. His dick was by now throbbing in his pants and he walked upstairs still carrying the phone.

The noise intensified as he climbed the stairs and to his surprise, he found his parents’ bedroom door wide open. Although the light was low, he could clearly see his father now kneeling up on the bed over her ecstatic mother, using both hands to jerk his inhumanly huge cock in the direction of her face. His mother was frantically masturbating and sounded very close to orgasm, managing between moans and squeals to say, “you gonna shoot a nice big load in my face Daddy?”

This was the trigger and his dad shot stream after stream of hot, high pressure cum over his wife as she made herself orgasm loudly. They both took a moment to get their breath before he watched his Dad eagerly flipped his Mom onto her back, her big tits swinging as he did it. He then pushed her legs apart and eased his still fully erect monster into her.

Jack was a little concerned about his mother’s safety here, but from the noises she was making and the filthy encouragement she was shouting, she was obviously having the time of her life. They rutted unceasingly in various positions for the next couple of hours. Each of them cumming endlessly and never really seeming to lose impetus.

Jack sat on the top step with a clear view into their room. He alternated the time between jerking himself off watching the real-life porno play out before him and getting his head around the app on the phone. He quickly realised the changes that had been made, although he had no idea how events had unfolded. He’d been engrossed in the multiple pages of the app and hadn’t realised that things had gone a little quiet in the room.

It was only when he heard his mother say, “oh hi baby, have you been enjoying watching us fucking?” followed by a giggle that he looked up to see his naked, cum drenched mother looking down at him. “I hope you filmed some,” she added, looking at the phone, “I’m sure your friends would love to see.”

Jack was speechless, unsure of what to do or say or where to look. His mom’s reduce intelligence meant that she completely missed this, smiled and said “look baby, I’ve told your dad to take care of himself for a minute while I go pee.” Through the door, his dad was frantically working his still hard cock with his hands, groaning and grunting like a thing possessed. “I’m actually a little worn out right now, otherwise we could have maybe had a little fun. Maybe tomorrow? I just hope your dad slows down soon.” She giggled again then pulled a cheeky, comedy sad face and headed to the bathroom.

What his mom was suggesting didn’t fully sink in at that moment. However, he’d noticed that the app control he’d guessed was giving them their superhuman sexual stamina was set rather higher on his dad than his mom. Taking pity on her, he brought this down to about 200% just as his dad flooded the bed one more time with a big load of spunk. His Dad’s dick quickly wilted and before his mother returned from the bathroom, he’d collapsed into a deep sleep.

Jack also pulled the same controller for his mother back down to 200%. As she passed him heading back into the room, she stopped, bent down and kissed him deeply, sliding her tongue into his mouth in a totally unmotherly way before saying “night night baby, I hope we can have some fun tomorrow. I’ve thought about fucking you so many times. If you’d like to come and snuggle in with us, I’m sure daddy won’t mind”. She giggled again before gliding back into the room and cuddling up to her husband unconcerned about the cum and juice soaked bedding.

Jack’s mind was once again blown. He’d realised that somehow his mother’s intelligence had been reduced significantly, which explained many of her actions. But where had this interest in him come from? He’d jerked off many times over the years at fantasies involving her, was it possible that she felt the same? Had the adjustment to her reasoning simply meant that she was expressing these desires without concern about societal conventions? He decided to let them sleep, he was excited by this idea, but also exhausted. He headed back to his room and stashed his dad’s phone under his matrass, slipped out of his clothes and into bed.

Jack woke up at around 9am. He could already hear the sounds of sex drifting into his room from across the hall. He pulled on some sweatpants, grabbed the phone and crept quietly down to his parents’ room. Clearly the 200% setting still kept them at a pretty intense level of arousal. The room was bathed in light, with all of the curtains drawn. His dad was pumping into his mother from behind, with her bent forward in the front window of the house, her face and big tits more-or-less pressed against the glass for any passer-by to see. As it was a Sunday, the road would have been pretty quiet. However, Jack guessed they’d probably given a couple of dog walkers a scare. He really needed a drink and headed downstairs.

Having shot another three loads into his wife this morning, John was still a little aroused, but spent enough to stop fucking for a while. He daren’t look at Kate too closely as he knew he’d quickly be hard again. Kate told him she wanted a shower and headed to the bathroom, which gave him time to get his thoughts together. He was interrupted to help Kate get the shower working as this was still beyond her reduced capabilities and nearly ended in them having another session in the shower.

John desperately needed to find his phone and change things back. What if Jack worked out what was going on? He’d no doubt heard the session this morning, but hopefully he’d not noticed anything unusual. And hopefully the neighbours hadn’t seen his wife’s huge new tits bouncing at the window. He felt his cock twitch as he pictured this, remembering how Kate had gone on about all the guys in the neigbourhood stroking their cocks to the sight. The thought of Jack listening to them was also making his dick throb a little.

John was fully aware that they often had a voyeur tuned into their sessions, so he knew that Jack would have been listening. John loved this thought, but it was a little kink he’d never share with anyone. No, he needed to concentrate and find his phone before things got out of hand again. He pulled on a t-shirt and found a pair of loose pyjama bottoms that could accommodate his gigantic bulge. It still looked pretty without looking too obscene, but he hoped it would do. He’d noticed the inexplicable additional growth of his cock, but was trying to ignore it as it just made him want to play with it. Then he checked the room over one more time, but no sign. He knew there was no way he’d left it downstairs, but he guessed he needed to check.

He stepped out of the bedroom just in time to see Kate, fresh from the shower and fully naked about to head off down the stairs. She saw him and smiled. “Hi daddy,” she chirped, “awww what made you hide your monster?” She giggled and gave his bulge a squeeze letting out a little sigh, her concentration drifting as she felt it react to her touch. It took all of John’s strength to resist this, but he needed to keep control.

“Where are you headed?” he asked her, snapping her back to reality. She gave him a dull smile, “I’m like sooo hungry baby. It’ll make me strong for more fucking later!” She laughed, her big boobs bouncing hypnotically. John tried desperately to maintain eye contact.

“Don’t you think you should wear some clothes to go downstairs?” he continued, hoping he could get this idea across, still concerned about Jack seeing her and unaware of what had already happened.

Kate pouted, “don’t you want to be able to look at my titties? Plus, I know Jacky definitely will.” She smoothed her hands over them finishing by tweaking her already rock hard nipples.

Jack thought quickly and an idea formed, “but we don’t want you to get cold my love. Plus its so much more fun if you reveal it all slowly”.

Kate screwed up her face as she considered this, she wasn’t entirely sure what the word “reveal” meant, but she got the idea, “ooooh, you naughty boy, I know how you like me to tease, I’ll go find something fun to wear!” With a little bounce she headed off into the bedroom chuckling at the idea of having a sexy little game to play.

John hoped this challenge might keep Kate occupied long enough for him to find his phone and get things back to normal. He rushed downstairs and started turning over the living room despite being certain he’d taken the phone to bed. A few moments later Jack, having heard his father, emerged from the kitchen saying as innocently as he could manage “Hi Dad, everything OK?” John jumped, so absorbed in his hunt that he hadn’t noticed Jack.

“Oh, Hi Son,” John replied, “sorry, I’ve lost my phone and I really need to find it.” Unable to hide the rising panic he was experiencing at that moment. He knew that once Kate appeared there would be no hiding that something was going on. Plus, his mind was currently playing games with him. Thoughts like “maybe if you just got off one more time you’d be able to clear your head” and images of Kate swallowing his engorged cock floated around in his brain and were becoming increasingly difficult to ignore. Jack had noticed that his father was reluctant to stand and turn around, knowing full well why this was.

Jack was actually concealing a throbbing hard-on of his own right now just considering his dad’s predicament. “I’ve not seen it Dad.” Jack lied, “when did you have it last?”

John continued searching, “well, I was sure I took it up to bed last night.” he replied.

Jack couldn’t help but stoke the flames of the situation. “Why do you need it so bad, it’s Sunday?” he probed.

“I, um…“ John stuttered, desperately trying to think of a plausible reason why he might have to have the phone now.

“Maybe ask Mom if she took it.” Jack interjected and almost as if he’s summoned her, this was the moment Kate started coming down the stairs.

In the intervening time, Kate had gone through her entire wardrobe and been utterly disappointed. She’d got nothing that would show her body off well enough. She’d become too self-conscious recently to show more than a bit of leg and a little cleavage, despite encouragement from her husband. Recently, Lucy had encouraged her to show off a little more, but she’d just been too worried about how she might be judged. It had been much easier when she was younger and easier still when she was wasted.

Thinking about Lucy, led her to what she thought was a brilliant plan. Lucy had said she could borrow her clothes any time she wanted, so maybe she should go to Lucy’s room to look. She started in the drawers by the bed, but these only contained underwear and Kate had already decided that was pointless. In the third drawer she uncovered her daughter’s vibrator collection, which nearly distracted her from the task at hand. But Kate knew there were two real cocks downstairs to have fun with today. She could always come back to these later.

The wardrobe and main chest of drawers yielded what Kate was looking for. First was a stretchy white crop top which Kate just about managed to pull on over her tits. The combination of Kate’s lack of coordination and focus and the fact that the top was much too small for her would have made comical viewing for anyone looking on. She eventually got it over her big tits, although it only came two thirds of the way down, barely concealing her stiff nipples which were almost acting like hooks holding the bottom in place. The low neckline was also stretched to its limit creating a chasmous display of cleavage.

She admired herself in the mirror, squeezing her tits together and pinching her nipples to make them even more prominent. Her mind wandered back to the contents of Lucy’s toy drawer, in particular the thick vibrator. No, she had to keep going. She pulled on a little pair of denim shorts she’d found which would have been tight on Lucy’s slightly slimmer form. Kate just about managed to get them over her hips and butt, but there was no way the zipper was coming up more than a couple of centimetres. She again regarded herself in the mirror. The gaping fly of the shorts looked so sexy, drawing attention to her pussy and revealing just the top of her pubic region. She was rocking this look she thought. Time to show the boys!

Kate flounced excitedly down the stairs, tits swinging wildly as she did it. Jack and John stopped dead to watch her make her entrance. Jack afforded himself a glance at his father who was clearly battling with his arousal. Hiding John’s erection was now a lost cause and it created a kind of sideways tent in the front of his sweatpants. Kate bounced past John, giving his cock a little squeeze and saying, “ooooh, looks like someone’s pleased to see me!” but was making her way for Jack.

“Good morning baby, are you pleased to see Mommy too?” she asked giggling and wrapping her arms around his shoulders. Jack just had a few seconds to take in her tits before she leaned in and planted a long, deep kiss on his lips, her tongue probing into his mouth just like it had the night before.

Watching this display pushed John’s dick to full erection, making it pop out over his waistband. He slid two hands over his cockhead in a vain attempt to conceal it, enjoying the pleasure the pressure sent through him. “Um, Jack, I think I’ve done something really stupid, and I’m going to need to find my phone to put it right, like right now… please can you help” he pleaded with his son.

As Jack’s mother pulled back off him, he couldn’t help but chuckle to himself as he pulled the phone out of his pocket. “What, this phone?” he teased.

“That made my boobies big!” Kate chirped, giggling as she spoke. She reached down, eager to get a feel of what her son was packing.

“Yes, you need to let me have it right now!” John shouted, throwing himself across the room towards his son, mixed feelings of relief and extreme arousal were in full battle inside his head. He was confident that this would soon be over.

What he hadn’t banked on was that Jack was already prepared and definitely didn’t want things to be over. Jack flipped the phone around, having pre-loaded the “head” page of his dad’s profile. He’d realised the function of the intelligence slider and also why his dad had used it on his mother, keeping her in a state where she couldn’t work more complex devices and struggled to resist her base urges. Jack placed his finger on the slider and brought his Dad’s setting down a sizable amount.

John had been moving across the room at full tilt as Jack did this. The panic he felt seeing his son operating the phone and his stress at how he was going to sort everything out quickly dissipated. His head was suddenly flooded with all of the thoughts John had been trying to keep to one side. Fuck his cock was hard, he really needed to get off right now.

He stopped dead in the middle of the room, trying to get a plan together, his hands immediately grabbing his swollen shaft and starting to work it through his pants. A dim smile swept over his face as he took in the sight of Kate in front of him again. “Shit baby, I wanna get my dick inside you!” he slurred, taking his time as he struggled to think of the right words.

To be continued…
