Of course not

Courtney stood up, full of confidence and started naming "John, Matthew and Gilligan!" Her hand flew to her mouth.

"Courtney!!! What are you saying!" Connie screamed.

"I don't know why I said that."

"I'm pretty sure Gilligan wasn't an Apostle. I guess we all go swimming."

I stood up and pulled off my shirt. Everyone started to do the same. Bill looked at me "What about us?" we meant him and Frank

"I don't care, but you are both joining us in the pool." They also chose to swim in their underwear.

I wasn't surprised that both ladies wore boring plain white bras and panties. But I was very pleased with their bodies.

We all ended up in the pool. Connie kept chastising her sister for her flub. Even the husbands were letting her know how disappointed they were with her. She could only apologise.

They both stood in the pool, arms crossed to cover their tits.

"So Connie, you would have gotten it right?"

"Of course I would have."

"Well, let's put that to the test. Same question, you answer correctly and this swim ends now, you can dress and leave. You can even use the two your sister got right."

"Deal."

"Wait, if you get it wrong, then this turns into a naked day. We all spend the rest of the time together naked. Everyone."

"Fine, you have a deal."

"OK, name 3 Apostles."

With a confident smile she says "John, Matthew and Chucky" like her sister she is stunned. "Oh lord, no, I didn't mean that."

I smile "But you said it. Everyone has to pay up because Connie here is not as good a Catholic as she thought."

"Nice going sister." Courtney said as she was removing her bra.

Both sisters were stunning naked. Like I guessed, older versions of their daughters' with bigger tits. Frank and Bill couldn't help but stare at Tammy and Laurie as they also stripped.

The moms were stunning, but they both neatly trimmed pussies.

The dad's were trying to not look at their naked daughters. The girls for their part were perfectly comfortable.

Connie looked at her daughter as she was getting out of the pool. "Rebecca! Why have you done that?" she was looking at her waxed pussy."

Becky looked down "Hey, It would be covered up if you hadn't lost the bet." That shut her mom up.

The two new couples stayed in the pool, while the other 8 of us were lounging about, having drinks.

"You know, you can't stay in the pool forever. Plus we've already seen it all.

"Listen, the bet was naked until we leave. It didn't say anything about where we had to be." Courtney said.

"Good point. But I think it's time for me to come clean. You see, yesterday the kids here also lost a few bets."

"What kind of bets" Frank asked.

"Emily, tell your father what you lost."

She had a little smile on her face as she looked at him "Well, Becky and I are basically sex slaves to Joe and Rick until we leave. We lost a series of bets and our useless boyfriends also lost bets and this is where we are."

"Are you saying you've had sex with these men?" Bill asked

Becky looked at him "Dad, they've fucked our brains out and we've also fucked their wives and each other."

"Oh my lord" Courtney exclaimed.

"Mom, we don't have a choice. We lost the bets."

"I understand, it's just so shocking."

"I can't believe this." Frank said

"Well, I have proven to be reasonable. How about a bet with you and Bill. If you win, not only will everyone have to dress again, but I will call my bet with your sweet daughters off. And trust me, that is a big loss for us, because fucking your daughter while she eats out my wife is such a great thrill." to emphasise my point, I grabbed a handful of Emily's tight ass.

I could tell he wanted to be mad, but since I won the bet, there was nothing I could do. "OK, what's the bet?"

"You both seem quite fit. Simple, get out of the pool, run to the dock and back in 5 min."

He looks back, the dock is about 200ft away.

"No tricks. That dock over there?" he pointed.

"Yup. Run over. Both feet anywhere on the dock and back to the deck, within 5 min."

Bill got out of the pool, his cock half hard. "Deal!"

"Wait, but if you lose"

Frank was also out of the pool "We won't"

"Fine, but if you lose, your wives will be ours, like your daughters for the next 5 days. You two will leave after dinner and come back to pick them up when we are done. During that time, we can do anything we want to them and they have to obey every command. Deal!"

"Just start the clock." I set 5 min on my phone. "Go"

They barely ran "Run you morons." Connie yelled.

"Honey, it's a 400 ft round trip, we got this."

This turned into a "Tortoise & the Hair" fable. They joked and walked, pretended to trip. Laughing at how easy this was going to be. They got on the deck with 3 min left.

"Frank, just run back here." Courtney yelled. She was leaning out of the pool, her tight ass fully exposed. Connie was beside her and I couldn't decide which had the nicer ass.

"Bill, please just run back."

They continued the joke, taking their time, positive they would win.

They were standing at the stairs to the deck with 1 min to go, when they both just sat down, panting.

"What are you doing. Get on the deck!" Connie yelled.

Bill looked at her, panic in his eyes now, unable to speak, too tired to stand.

Frank was in the same shape, struggling to get up.

"30 seconds." I said

"GET UP!" they sisters yelled. They kept yelling, pleading for their husbands to get up. But it was all for nothing. The men just couldn't get up, they collapsed at the steps as my phone started to beep.

"Times up. You lose." The men, suddenly having the strength stood up and ran on the deck.

"OMG, what did we do?" Frank said.

"You lost you moron. You had to play the big shot. Now my sister and I have to do anything they say." Courtney said to her husband.

"Yes you do, so lets start with getting out of the pool and come here and let us get a good look at you."

They both got out of the water, one arm covering their chest, the other their pussies. They stood before us. Connie in front of me, Courtney in front of Rick.

"Drop the hands, now"

They both did. We all admired their naked bodies.

"So, for the next 5 days, what will you do?"

"Anything you ask us to." they answered together.

"Good." I turned to Rick "What do you think?"

"I'm ready to fuck them now."

"Good call. But first, girls, suck us hard for your moms."

Becky knelt in front of me, Emily in front of Rick and they sucked on our cocks, while their moms watched. I could already see they were both getting excited.
