Part-3: Las Vegas
(This part of the story makes more sense if you've already read Part-2.)
Ryan's father, Jay, and Penny's mother, Sally, were lying naked on the big king-size bed in their hotel suite. Between their legs, were Suzy's parents.
Ginger was sliding her hand and her mouth up and down Jay's hard cock, and Ron had his face pushed firmly into the soft wet folds of Sally's pussy as he poked his tongue as deep into her cunt hole as he could make it go.
The two couples had known each other, socially, through school sports since their kids were in grade school, but had now been swinging for several years; since before Ryan and Suzy had even started dating. They got together for sex once a month, or so, but they always used Jay's annual Las Vegas convention trip as a special weekend of hot sex.
After a long, hard suck on Sally's clit, while he had three fingers deep in her cunt hole, Ron lifted his head, and said, "Switch?"
He and his wife quickly traded places, and as Ginger took over on Sally's pussy, Ron put his mouth over Jay's cock head, and began sucking as he stroked its saliva-wet length.

The opening up of the couples' bisexuality had happened gradually.
Although it didn't take too much persuasion for the two guys to get their wives to experiment with girl-girl sex,
they
were a little more hesitant.
Although each was secretly curious about the taste and feel sensations of the oral sex that their wives seemed to enjoy giving so much, it was somehow a harder line to cross.
The barrier was finally broken one night, when Jay lay underneath Ginger, in a 69, and Sally guided Ron's cock to his wife's pussy while Jay was lapping at the soft wet lips. In the heat of the moment—with his own dick being sucked by Ginger—Jay didn't even move his mouth away as Ron's cock slid between Ginger's pussy lips, and over his tongue.
As Ron fucked in and out of his wife, Jay ran his mouth and tongue all across Ginger's pussy, alternating between lapping her cunt, and lapping Ron's shaft. At one point—whether accidentally or not—Ron pulled all the way out of his wife's pussy, and his hard cock fell directly onto Jay's face. But Jay didn't try to pull away; instead, he opened his mouth, and let Ron slide his dick between his lips as he rocked forward.
Jay lapped and sucked at the hard, hot flesh as Ron fucked his mouth several times, neither of them the least bit put off by the newly-broken taboo, but one-hundred-percent into the new sensations.
As Sally watched the action at Ginger's pussy—hoping something like that might transpire—she let out an encouraging, "Yes! Oh, yeah, baby, suck on his cock! Oh, man! That is so hot!"
Wanting to witness her husband do the same thing, the group soon switched positions, and Ginger watched, up close and personal, as Ron took Jay's cock in his mouth after it had been good and soaked in Sally's cunt.
After that, Ron and Jay had become as uninhibited about sucking cock as the girls were about eating pussy.
*****
Coming out of the shower half an hour later, Jay picked up his phone to check for any messages; he was, after all, in town on business.
Finding nothing important, work-related, he then sat down, naked, and flipped to another app on his phone.
"You want a drink?" Ginger asked him, as she came out of the bathroom, also naked, and heading for the bar.
Jay looked up, and watched her shapely ass cross the room.
"Yeah, vodka and tonic would be great. Thanks. Lots of ice," he replied, and then went back to scrolling on the little screen.
As Sally and Ron—fresh from their shared shower, and equally naked—joined Jay and Ginger in the living room of the suite, Jay let out a laugh at what he was watching on the screen.
"What have you got there?" his wife asked.
Jay closed the app on his phone, and answered, "Let me show you on the laptop; the phone is way too small to really appreciate this, I think." As he booted up the computer, he added, "In fact, let me set up the projector."
"That good, huh?" Ginger said as she set his drink on the table.
"I only saw a little bit of it, so far," he answered, "but yeah, I think it's going to be that good."
He had his small presentation-projector set up in a couple of minutes, and with the image of the laptop screen filling a big blank area of a wall, Sally turned off the room lights.
Jay clicked the button to start the video, and the projection changed to a scene of Jay and Sally's family room, with Ryan and Suzy walking into the picture.
"Is this live?" Ron asked.
"No," Jay answered. "It was recorded a few hours ago."
"You have a security camera in your family room?" Ginger asked. "Why?"
"Actually it's one of those nanny-cams, and I just got it before we came up here this weekend," Jay relied.
"Again,
Why?
" Ginger repeated as they watched Ryan and Suzy settle onto the couch after having started a video that was out of the nanny-cam's view.
"I have to admit that it was the pervert in me," Jay said. "I wanted to watch Ryan and Sally getting it on. And I was obviously right that they'd use our family room while we were all away."
"I'm not too sure that I want to watch your son poking our daughter," Ginger said. "That seems a bit weird."
"That's only because you're not as perverted as Jay," Sally said with a chuckle.
"You're okay watching this?" Ginger asked her as Ryan began to feel Suzy's tits, up on the image on the wall.
"Call me perverted, too," Sally answered, "but I've always thought that Suzy had a really cute shape, and I've wondered what she'd look like naked."
"And Ryan?" Ginger asked.
"I saw him jerking off in the shower one time," Sally replied, "and that image has never left my mind."
Ginger chuckled a bit nervously, and said, "I guess I've always thought that Ryan was pretty hot, too. I have to admit that the image of him and Suzy together
might
have entered my mind, one or twice."
"Now, you get to see it for real!" Ron said.
Although the two kids kissed and groped one another passionately, the action was a little slow by porn standards, and Ron said, "Can you fast-forward this, at all?"
"Patience," Jay said. "I saw a little bit of the end of the recording, and I'm gonna bet that you won't want to miss anything between here and there. I know
I
don't!"
As Jay was speaking, Ryan began unfastening Suzy's jeans. When he slid them down, Sally commented, "Whoa! No panties! She came prepared!"
"No hair, either," Jay commented. "That's a pretty little pussy."
"Hey, that's my daughter you're talking about there!" Ron said in mock indignation.
"I don't see
you
leaving the room," Jay replied.
"Fat chance of that!" he said with a laugh. "This is finally picking up speed!"
As they watched Ryan kiss Suzy's pussy, but not really
go down on her
, Ginger commented, "Hmm. He's got a lot to learn about
that
!"
"A lesson you'd like to give him?" her husband said.
"I think I could be talked into it," she replied.
"Get in line!" Sally said, and they all laughed.
They all watched as Ryan unbuttoned Suzy's blouse, laid it open, and began kissing her nipples.
"Nice tits," Jay said.
"I'd like to give him a lesson on sucking on those, too," Sally said.
Ron began to make a comment about his naked daughter, when the image on the wall was blanked out by something moving right in front of the camera. As it moved on, it became obvious that it was a naked ass.
"That's Penny!" her mother exclaimed.
"Holy shit!" Ron said as they watched Penny drop to her knees and put her face between his daughter's legs.
"Oh, my God!" Ginger said watching her daughter get her pussy licked by her boyfriend's sister. "Did you know about this?" she asked Sally.
"Not a clue!" she answered, and turned to her husband. "Did you?"
"I'm as surprised—and delighted—as the rest of you," he said. "The best I hoped for when I set up the camera was Ryan screwing Suzy, and maybe getting a blow job.
This
sure never entered my mind!" He chuckled, and added, "And
I'm
a pervert!"
By the time the girls were jerking off Ryan all over their faces, Ron and Jay were stroking their stiff cocks, and Sally and Ginger had their hands at their pussies.
When the video got to the part where Ryan had his face buried between his step-sister's butt cheeks, and was obviously tongue-fucking her ass hole, Ginger commented, "Maybe he doesn't need as many lessons as I thought."
As they watched Ryan fucking his step-sister up her cunt while his girlfriend sucked and lapped at the wet widely-spread lips, Sally got up, and said, "I need some cock!" She moved over an straddled Ron's legs—still facing the show—letting him guide his stiff hard-on into her wet cunt hole.
She lowered herself until every inch of Ron's cock was buried inside her, and then she began to rotate her hips, gently fucking herself.
Ron reached up, cupped her tits, and started to pull on her nipples.
"Me, too!" Ginger said, getting up, and taking Jay's hand.
She turned one of the chairs around, knelt in it, and leaned on the back, facing the video on the wall, with her naked ass facing Jay.
He rubbed his dick up and down through her pussy lips a few times, and then leaned forward, and drove all the way up her juicy cunt in a one push.
"Oh, yeah! Fuck me!" she said. "Fuck my cunt like you'd like to be fucking Penny right now!"
"Shit, yeah!" he said as he rammed his cock in and out of her, while squeezing her tits, but keeping his eyes glued to the video.
By the time Ryan was fucking Suzy while Penny ate her pussy, the parents had swapped partners, and were now fucking their respective spouses.
They all would like to have gotten into oral sex on one another, but they couldn't figure out how to do it and be able to see the show at the same time.
They watched, excitedly, as Ryan pumped his cum into Suzy's cunt, and Penny lapped at the overflow, but were then surprised when Penny twisted Ryan and Suzy around, and then as she finger-fucked Suzy's tight little ass-hole, Ryan sucked his own cum from her fresh-fucked pussy.
"Holy shit! A cream pie!" Ron said. "You think maybe
he's
