Probably a long T-shirt over nothing much

"Now go have fun." Sally said as she stood up from the table. She kissed her son, then Sandy, then Kathryn and finally Bryan. Lover kisses, lips-to-lips, deeper with Peter and Sandy, gentler with Kathryn and Bryan.

Jim echoed Sally, "Go have fun." He put a hand up the leg of Peter's loose shorts, squeezing his son's half-erect penis. "I can tell the day hasn't worn you down." Peter laughed. "Got your traveling fun kit?" Jim asked.

"Got it here, Dad," Peter said. He patted the side pocket of his light jacket. He hesitated for a second, then kissed his dad's lips. "Thanks for everything."

The two younger couples stepped out into the warm summer night, Bryan guiding Kathryn as they went hand in hand. They got into Peter's car and started the drive to Peggy Wise's apartment. Sandy in the front seat with Peter, and Kathryn and Bryan cuddling in the backseat.

Peter glanced to Sandy, "So what do you think your sister will be wearing when we get there?"

"Knowing her?" Sandy said, "She'll probably be wearing one of her big T-shirts over a sports bra, or over her swim suit if she's been in the pool."

Peter chuckled.

"Okay, maybe no sports bra," Sandy said. "And maybe the shirt won't quite go down to her knees."

"Or maybe it won't cover her butt," Peter said.

Sandy laughed. "Or maybe not."

"So tell us more about Peggy!" Kathryn said from the back seat. "How did she get you two into all this stuff?"

Sandy said, "Well, you know, Peggy's an airbrush artist. She does custom shirts and car art and skateboards and stuff. I don't know exactly how she got hooked up with the parties, but I think it's someone she knows through her work. That's it, it was through doing a custom headboard for somebody's bed." Sandy laughed. "I think the motto on the bed was, 'The More the Merrier', and the art was like some kinda orgy with movie stars and superheroes and all kinds of crazy stuff."

Kathryn laughed. "I guess if you're an artist doing commissions, you meet people living the high life."

"Yeah," Sandy said. "So I guess knowing them was her way in, but there are better and worse groups, y'know, of regulars. Peggy started going to the parties, but it didn't take her long to settle on a favorite group. It seemed more established, with a lot of regulars, some a little older, and they kept it from getting out of hand, the way some of the other parties did."

A line from Guys and Dolls about Nathan Detroit's dice game ran through Bryan's head, and he blurted out, "The oldest established permanent floating sex party on the coast."

Kathryn pinched him.

Sandy giggled and sang back to Bryan, "Let's keep the party polite. Never get out of my sight. Stick with me baby I'm the fella you came in with…"

"Luck be a lady tonight!" Bryan and Sandy sang together.

Peter laughed. "You two."

Sandy cleared her throat. "But yeah, Peggy said she liked this one party because it was polite, that way. No **** there, so that helped keep things in line. So when I told her I was interested, that was the one she invited me to."

Peter said. "Yeah, so after I met Sandy and we'd been seeing each other for a while, she told me about the parties. So I said I was game, and we talked about some ground rules."

"Yeah," Sandy said. "Peggy and I talked about that kind of stuff, what if you brought a date to the party. Or your boyfriend. What sort of stuff is okay. Speaking of that, is there anything I shouldn't tell my sister about what we did the cruise? Kate? Bryan? Peter?"

"Wow," Kathryn said, thinking of everything that happened since Veevee Menard sweet-talked her on the closed sun deck the first day of the cruise. She imagined Sandy telling Peggy, 'Yeah, Kate sat on my face so I could lick her ass while her boyfriend was fucking me!' Kathryn took a deep breath. "Mmmm. No, I guess it's okay. Maybe leave out the, um, parental protective feelings stuff." Kathryn had felt loved and accepted, as well as, um, desired. But she was still feeling out her feelings.

"Okay," Sandy said.

Bryan felt Kate wriggle in his arms, the memories of the cruise manifesting in her body. Images flashed through his own mind. Amber from the crew bouncing on his cock while Kate fingered Amber's pussy. Before breakfast, on the bed with Peter's mom Sally fingering his ass while she sucked an orgasm out of him, Kate's pleasure-flushed face looking at his while Veevee masturbated Kate. Kate had really stepped out with the ladies this trip, it seemed like. Not that he minded.

"Huh, no, if it's all right with Kate, you can tell her whatever," Bryan said.

"Peter?" Sandy asked.

Peter laughed. "No, go ahead, tell her about mom and dad if you like," he said. "She knows them from the parties. She knows you and me. She'll understand. Just tell her not to spread it around."

Peter drove into the sheltered parking area under Peggy's apartment building and parked in a guest spot in the corner. They walked out and around past the pool, and up to the gate of Peggy's little fenced patio.

"The balcony up there is hers too," Sandy said. "She's got kind of a little townhouse unit, top and bottom."

"Can she see the ocean?" Kathryn asked.

"Yeah, it's a pretty nice view," Sandy said. She walked through the gate and pressed the intercom on the door. "Panty raid!" she joked.

A laugh sounded through the intercom, distorted by the little speaker. "Be right down," Peggy said. Peggy's voice reminded Kathryn and Bryan of Sandy's, but maybe a little deeper, with a brassy edge.
