The hot tub. They were all still dressed for it, after all.

"...alright," John said finally, "That hot tub actually sounds pretty good right now." Lily grinned and nodded, while Rose gave a short cheer as she retreated into the bathroom to change. In no time at all, she walked back out in a her pink string bikini, still damp enough to cling to her, something John tried not to stare at. Meanwhile, he and Lily were both still partially dressed, John in just his trunks and Lily in her bikini and tank top. They took a single room key- placed in Rose's handbag, and headed up towards the hot tub, chatting pleasantly the whole way.

The hot-tub Lily had seen was on the other side of the pool from the entrance. The deck was decently populated, plenty of people enjoying the pool and bar, though less than there were before. Most people were likely settling into their rooms or exploring the rest of the ship, waiting for the rest of the scheduled festivities to start over the course of the week. All in all, it felt pretty relaxed on the deck, and the trio was looking forward to kicking back in the pleasantly and surprisingly vacant hot tub.

"Aaaaaah..." Rose sighed as she slid into the tub, Lily and John following her lead. Lily slipped her phone into Rose's handbag, piling her shirt with it next to the tub, while her sister turned the jets up enough to cover the surface of the water in bubbles. "You were right, Lily," Rose said, "this was a great idea!"

"Glad you're enjoying it," Lily replied, "What about you, John? Glad you came?"

"Yeah, it's nice. I just kind of wish, y'know..." John trailed off as Lily shook her head.

"Yeah, it would have been cool if Maggie could have come, but you know how our Mom is."

"She means well," Rose continued for her sister, "but what that ends up meaning is that she doesn't like letting you go anywhere without her."

"She'll lighten up over the course of the vacation-"

"Hopefully..."

"-so we won't have to sneak around like this past today," Lily finished. The girls both looked at him, a little concerned, but eased up when John just shrugged.

"I get it," he said, "sorry for being a downer."

"Oh, stop!" Rose said, "you're fine! Let's just relax for a while, no more talking about this!"

And so they did. John had to say, it was really nice, talking to the two girls and relaxing in the hot tub. John was a little bit worried when Rose decided to pop over to the bar- using some cash she had on her so it wouldn't get charged to the room- and came back with drinks for her and Lily, but he figured that they were both of age, one drink wouldn't completely wreck them. Plus, added the little voice in the back of his head, seeing her half-jog across the deck in the bikini was nice too. The three just relaxed for a while, letting the jets push against their legs, the bubbles foam against their skin, and the just-cool-enough night air play across their top halves.

John was feeling really comfortable around the two girls when Lily decided she needed to check her phone, and John was treated to a view of her backside. She was leaning over the edge of the tub, arching her back as her chest rested on the rim, digging her phone out of Rose's handbag. This meant that her ass was pointed straight at John, covered only by the tight, black bikini bottoms that had only ridden up to expose more of her pale cheeks as she sat in the hot tub. As she looked at the small screen, her hips swayed back and forth absentmindedly, and John was hypnotized... until Rose's giggling snapped him out of it.

"See something you like, John?" Rose was grinning at the rapidly reddening boy across the tub from her. Lily noticed her sister speaking too, and seemed to piece things together quickly as she looked back over her shoulder. John saw her mouth tighten, but he couldn't quite tell if she was smirking or frowning; either way, she wasn't changing her position.

"He was staring at yours too, y'know," Lily said. John felt a pit in his stomach as his face grew warmer. "When you went over to the bar." While John was embarrassed to have gotten caught, and further embarrassed to have Lily explain it to Rose, the girl herself just smiled wider, though it certainly had an edge to it.

"I-I'm sorry! I just- I didn't mean to-" John stopped his explaining short as Rose turned, kneeling in the tub as she faced the same way as Lily. Her plus-sized posterior, clad in the pink string bikini, breached the surface of the water and joined Lily's bubble butt in facing John. He once again found himself staring, though when Rose placed her hands on her hips, John followed her arms up to her face, looking her in the eyes.

"Were you staring, John?" Rose asked, wiggling her ass at him.

"Well... yeah," John said, and even Lily snickered at that, "I'm really sorry."

"Oh, don't apologize!" Rose said, her thumbs moving underneath her waistband. "In fact..." John's eyes went wide as Rose bent over further, and pushed her bottoms down to just below her cheeks, exposing her massive behind and complete lack of tan lines to John while still covering between her legs. "How's this for a closer look!"

"Rose!" Lily cried, but she was laughing as she barely-admonished her sister. John meanwhile, was speechless; Rose's full moon was a hell of a sight, even as she pulled her suit back into place, and the display had his blood rushing in two opposite directions. His face was beat red, and the uncomfortable tightness in his trunks that had been growing since Lily had turned over was now a full hard-on, pressed firm against the netting of his suit. He heard Lily snickering and, with a start, realized she must have caught him shifting where he sat, trying to readjust himself. As the girls both turned back over John couldn't bring himself to meet their eyes, but he did hear them whispering to each other. When he found the two of them suddenly much closer in the tub, on either side of them, he **** himself to look up even through the embarrassment. Lily had her left hand on his right arm, and Rose had her right on his left. Rose also placed a hand on John's chest and a shiver went up his spine.

"Look, John," Rose said, and John could make out the faint smell of her drink from earlier, "we're sorry for poking fun at you, but that's what this trip is about, right? Having fun?" John glanced between the two sisters. Their expressions were soft, but they were holding his arms with a strange amount of ****.

"Y-Yeah," John said, forcing himself to chuckle, "right. I mean, I'm having fun."

"Good!" Rose said, and leaned in close to John, her chest dangling in front of him, not an inch from touching his own. "In fact, me and Lily had an idea for even more fun," she whispered into his ear.

"Oh yeah? What did you, uh," John paused, gulping, his mouth suddenly very dry, "what did you have in mind?"

Rose smiled. "Oh, I don't know... Maybe something like... this!" On the last word, Roses hand slid down his chest to join Lily's suddenly at his waistband. John realized too late what was happening; struggle as he might, both girls had one of his arms pinned each, and there was nothing he could do as they pulled his trunks down. His erection popped out into the bubbling water as his suit was pulled down past his crotch, down past his knees, his feet, and off! As the girls released him and pushed to the other side of the jacuzzi, John started to push after them- but the motion was bringing his crotch closer to the surface of the water, and as he felt the foaming bubbles play across the tip of his penis, he quickly sat back down, arms darting into the water to cover himself.

"G-Guys!" John cried, then quickly glanced around. None of the other cruise-goers seemed to be paying them much attention, but if John kept shouting, someone would be bound to catch them. "What the hell?!" he hissed, a harsh whisper turning into a scared tremble. Lily and Rose were laughing up a storm, his trunks firmly bundled up in Rose's hands. His question brought their attention back onto him, and much to his dismay, the two sisters...
