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.
