Kevin and his friend Peter had been licking each other's sons Joe's and Jack's asses through their tight shorts for 15 minutes or so before they switched and performed the same activity on their own son's asses. The shorts the younger men were wearing were exceptionally tight, accentuating the firmness of their buns while enhancing the long narrow lines of their ass cracks.
"Fucking hell, dad," said Jack, "your tongue feels just as hot licking my tight white shorts ass as Kevin's did."
"Dad's always been an expert rimmer," said Joe as his dad Kevin's tongue continued to work its way all over the back of his tight blue shorts. By the time their dads came up for air, Joe's and Jack's shorts were covered in several damp patches left there by Kevin's and Peter's saliva.
The two elder men shook each other's hands to signify a job well done as Joe and Jack, who had been bent over for so long, now got themselves back into a standing position. All four men had earlier released their dicks and balls from their shorts and were now eager to go a stage further and get completely naked.
"I think its time we got undressed, Joe," said Jack as he started to remove his clothes with Joe likewise now dropping his shorts. It took less than a minute for them to divest themselves of all their clothing, then they stood full frontal nude in front of their still dressed fathers with their aroused pricks so hard they pointed directly to the ceiling, their balls hanging low.
"Fucking hell, Peter," said Kevin, "our lads dicks and balls seem to get harder and bigger every time we see them. They're not just a couple of hot asses."
"Absolutely sensational," said Peter as he and Kevin began to gently masturbate their own hard-ons which they had released from their shorts earlier. "No fathers could wish for two hornier sons with dicks as spectacular as theirs."
"Yeah," said Kevin, "and we made them."
"With a little help from our moms," said Jack, laughing.
"Feels great being naked, hard and horny in front of you," said Joe, as he pointed his hard-on towards the two hungry fathers, prior to getting it incestuously sucked.
"Yeah," said Jack, "just as it did exposing ourselves to our moms yesterday."
"That's how it should be," said Kevin, "showing ourselves off with no shame is all part of the proceedings."
Joe and Jack, now completely naked, were impatient for their dads to get naked too. "In that case, dad," said Jack, "you and Kevin get yourselves out of those shorts and start showing yourselves off too."
"Yeah," said Joe, "those hard-ons and balls of yours look really good poking out of those skimpy shorts but you'll feel a lot more excited once you get them off and we're all naked. Its just as hot and horny as the sex itself."
"No sooner said than done," said Peter, "but we couldn't resist licking your asses through your shorts first."
"Fucking did," said Kevin, "and if you play your cards right, you'll get your nude cheeks and assholes kissed and rimmed too."
"Great, dad," said Joe, "but first I've got a present for you."
"Its not my birthday..." began Kevin.
"Not even Christmas," said Peter.
"Don't worry, dad," said Jack, "I've got a present for you too. We don't need special dates to show how much we love you."
"The hell we don't," said Joe as he and Jack and their undiminishing hard-ons stepped the few paces across the room until they were in front of their dads and Kevin and Peter went down on their knees to receive their presents. The two younger men held their proud hard-ons aloft as the older men opened their mouths and took their own sons' inside, gasping as the long incestuous poles slid effortlessly into the furthest recesses of the dads' mouths, the engorged knobheads hitting the back of the paternal throats while their balls began to slap against the undersides of their fathers' chins.
Joe and Jack smiled at each other and then leant across to indulge themselves in a kiss as their fathers went to town with their blowjobs, upping the tempo while reaching round with their hands to grab their sons' now bare ass cheeks and hauling them in closer.
"Go down on my balls, dad," said Jack, after Peter had been sucking him for 10 minutes or more, "get them nice and wet." A request to which Peter immediately complied.
"I'll have some of that too, dad," said Joe, "my balls are aching to feel your tongue on them."
Kevin had no hesitation neither in doing what Joe had requested, he immediately ran his tongue over his son's balls which Kevin was proud to see were as big as his own. Jack's balls were delightfully on the large side too as his eyes rolled in his head while thrilling to Peter's balls-licking skills.
"Fucking hell, dad," said Jack, "you're just as good licking balls as you are sucking cock."
"So's my dad," said Joe, "but I think its swapping time again."
"That's a great idea," said Peter, releasing his now smoking hot tongue from Jack's spectacular and now very wet balls, "I was wondering how long it would be before we got round to that again."
"Me too," said Kevin as their sons took up new positions in front of each other's fathers. Again, Kevin and Peter couldn't resist reaching round with their hands and touching up Jack's and Joe's smooth asses as they pulled the younger men closer into them and resumed sucking the two majestic hard-ons as they swapped their handsome naked sons.
2.
After sucking each other's sons' dicks for what seemed an eternity, Peter and Kevin got down to some real incestuous sucking as they swapped their sons again and began to lick their balls before taking the full lengths of their hard-ons into their hot paternal mouths. Joe and Jack both gasped in unison as their engorged knobheads hit the back of their own fathers' throats, making Peter and Kevin gag as they held their sons' balls in one hand while, typically, reaching round with their second hand to stroke the two smooth ass cheeks as they drew their sons towards them. Joe and Jack began to rock back and forth on their long athletic legs and as their fathers released their holds on their asses, their places were immediately taken as Joe began to caress Jack's ass while Jack also started to fondle Joe's buns at the same time.
Peter momentarily let Jack's dick escape from his mouth as he looked up at him, a proud smile on his face. "I want to see you lads kiss while your dads suck your dicks. You'd like that too, eh, Kevin?"
Kevin was too far gone enjoying himself feasting on Joe's dick but managed to give a thumbs up sign to Peter. As both dads continued sucking, now with their eyes cast upwards, Joe and Jack leaned in and took each other's tongues into their mouths and kissed for all they were worth.
"Fucking cock suckers," said Jack as he let his incestuous prick fall from Peter's mouth, after 5 minutes of snogging Joe, "this is just as smoking hot as when our moms sucked our dicks yesterday."
"Yeah," said Joe, "shame they're not here now, then our families would be complete."
"Aren't we good enough for you, then?" said Peter.
"You know I didn't mean that, dad," said Jack, "you're every bit as good."
"If not better," said Joe.
"Don't let our moms hear that," said Jack.
"I'll show you, young men, just how good your dads can be," said Peter. "We promised we'd lick your asses through your shorts and now the time has come for you to have them licked and feel our tongues minus those sexy shorts."
Kevin wasn't going to miss out on this neither as he let Joe's dick fall from his mouth and, without waiting to be asked, the younger men turned and again bent their bodies forward until their asses were again on display to their dads, only this time in the nude.
"Fucking hell," said Peter, "will you get a look at our lads' strong sexy butts."
"Absolutely divine," said Kevin, "no dads would wish their sons to have better sexier butts than the ones on show now."
