"So what's the plan?" I asked Guy.
It was Wednesday evening and he and my son Jake were slouched on the settee working their way through a pack of beers while I was sitting opposite with a glass of wine.
"I dunno," Guy shrugged. "It's gonna be a difficult one. We're gonna have to play it dead careful 'cause I sure as fuck don't want him tellin' any tales to his mother."
We were discussing what we were going to do on Friday night when he brought his own son, Simon, around for a little get-together at my house. That in itself wouldn't pose much of a problem, but Guy had an ulterior motive which made detailed planning absolutely essential.
"You still want to start playing around with your kid then?" Jake asked without taking his eyes from the movie the three of us were half-watching.
Guy chuckled. "He's your age, Jake... just gone twenty-one. Don't make this sound any more weird than it needs to..."
"You wanna shag him, though," Jake persisted, still staring at the TV. "I mean, that's your ultimate aim...?"
"Not necessarily," Guy replied. "I just really like what you guys have together. The way you use each other for sex is kinda logical really... you're both men and you both get horny so sometimes you help each other out. That's how I want it to be with Simon."
"You want to get sexual with your son?" I asked. "You're absolutely sure about that?"
"Maybe not at first. I want him to see how it works with you pair... how natural it looks for a dad and a son to get physical together..."
"You want us to get intimate in front of him?"
He shrugged. "Perhaps, yeah... but nothing too heavy. He's gonna freak out big time if you guys treat him to the demo you showed me..."
We'd been staying over at a Travel Lodge before going to the Liverpool match. Jake and I had surprised our companion by showing him that we'd started having occasional but extremely fulfilling incestuous sex. My son had bobbed down to consume a good half of my large erection in front of Guy's disbelieving eyes and then we'd awoken him next morning by Jake taking me roughly from behind as we'd squatted alongside him.
"Maybe we play a game of 'Twister'," Jake suggested. "I end up with my face in my dad's butt and say, 'Oh Jesus, his arse-crack smells so fucking horny!' and Simon'll be like, 'Aw fuck yeah... I gotta have a sniff of daddy ringpiece for myself!'"
Guy sniggered but shook his head. "Come on, buddy. You know as well as I do that Simon's not like that. He'd run a mile if he had to shove his face in my arse. I'd be up for having a sniff of his, but if I did he'd probably run a mile too!"
"But maybe the game idea is worth pursuing," I proposed. "It would keep things light-hearted."
"How about strip poker, then?" Guy asked. "Once we're all stripped down to the buff, we change the rules so the loser has to wank the winner. Simon gets to see Jake giving daddy's big dick a good pullin'... so next time when he loses he won't be so shy about reachin' over and playing with mine!"
"Can you really see Simon agreeing to play strip poker?" Jake laughed. "I guess we could start out playing for pennies or something, but even then he'd probably say he felt uncomfortable with gambling."
"I agree," I chipped in. "The game would have to be played purely for fun but then gradually manoeuvred in a sexual direction."
"Okay..." Guy replied, staring over at the fireplace as he struggled to come up with something that would fit both requirements, perhaps thinking back to his days on the oilrig.
"Truth or dare?" Jake tentatively offered.
"Yes... that's more like it," I agreed. "How about we make it a card game and arrange the order of the tasks very carefully beforehand...?"
Guy looked unconvinced. "So how would that work?"
"We can have the top cards giving people silly dares at first, but we can set it up so that after a few rounds Jake's task is to get the person to the left of him sexually aroused... which will, of course, be me."
"Okay," Guy grinned. "I like where this is going!"
"Jake will whisper stuff into my ear and I'll deny that I'm getting at all turned-on and then you, Guy, will insist that everyone can see whether I really am becoming aroused. After some initial reluctance from me and hopefully some persuasion from Simon, I'll pull my penis out through my trouser fly and show the room that it might be long and thick but it is unquestionably limp."
Jake asked, "You won't mind Simon seeing your todger?"
I shrugged. "I used to take you pair camping when you were younger... he's seen the thing swinging around between my legs many times before..."
"Okay," Guy chuckled, "since sonny-boy's whispering hasn't done much for daddy's droopy dick, Jake resorts to reaching over and having a little fondle of it!"
"Oh sweet!" Jake guffawed, just about to take another swig from his beer. "That'll be so cool... Simon watching me having a squeeze of my old man's donger sticking out from his fly!"
"And what will you be doing?" I asked Guy.
"Cheering and egging Jake on... trying to get Simes to join in... I reckon he'll up for it, actually... he'll probably find this really funny..."
I smiled. "So I say, 'Okay, it's getting a bit stiffer, I think that's a win, Jake.'"
"And I'm like 'No way!'", Guy laughed, becoming increasingly enthusiastic about the plan. "I call over, 'Come on, guys, the dick's gotta be fully hard! I wanna see the bell-end go shiny... that's the sign of a proper boner!'"
"So I wrap my hand around your big knob and start wanking you off," Jake grinned at me. "I mean, actual masturbation... with your foreskin sliding up and down."
"Aw yeah!" Guy chortled. "And I'll be like, 'Oh my God... this is so fuckin' funny!'"
"Would you still be okay with that, dad? Having Simon seeing my wrist bashing away and making your cock grow a stiffy!?"
I thought about how we would look: me perched on the settee with my large phallus exposed through my gaping zipper and Jake reaching across to eagerly stimulate it. Simon would likely look surprised - though hopefully also amused and intrigued - watching his friend masturbating his father right in front of him. I'd chuckle back at him as my manhood achieved its full proud stature inside the grip of my son's fingers, until the domed helmet throbbed as two shiny purple lobes.
"Yes," I grinned, "I think I'd rather enjoy it!"
Often when Jake's sleepover buddies are lumbering out of his room for a pee in the morning, I make enough sound from behind my half-open bedroom door to let them know I'm enjoying a moment of self-induced pleasure. Sometimes a young man will creep along the corridor to take a peek at their friend's father vigorously tending his morning hard-on. I sit opposite the door so that if an inquisitive face cranes around it, I can smile at the young man while my hand pumps frantically up and down, and my two big bollocks slap up against my fist. Occasionally my performance will be rewarded with a cheeky smirk and a growing bulge in the boxers, in which case I flaunt my huge erection as I wank it until we're both staring, mesmerized, at my blasting gusher of cum.
"Perhaps Simon will too," I mused. "Some young men find the sight of mature male masturbation very appealing!"
