Ray

Unsurprisingly, Ray was the first to speak up, "So Paula, when you were showing me your butt, I couldn't help but notice something odd."

"Oh really?" Paula asked, both curious and amused, "Do tell."

Ray made a show of sheepishness that Leo immediately knew was staged, "Well, it's kind of awkward... promise you won't get mad for bringing it up?"

"Yeah, I promise," Paula replied.

Ray smiled the smile of someone whose trap was successfully sprung. Lowering his voice just a tad, he said, "Okay, so I know this may be a bit presumptuous of me, but was that a vibrator I saw sticking out of your pussy?"

Leo was pretty sure the girls' pussies weren't even visible during the mooning, but thanks to the magic of the ring that didn't matter. Paula's face went red with embarrassment, and she answered with a quiet, "Yeah."

"Is it on?" Ray whispered, his grin now outright devilish.

Paula nodded, her face grew redder, and Leo swore he could now hear a faint buzzing coming from Paula's seat.

"Eww, seriously Paula?" Polly asked, giving her sister a look of disgust, "Why do you have that in there?"

"I thought no one would notice," Paula replied, her voice getting breathier as her arousal builds.

"Well, he did!" Polly snapped.

"Is it a regular thing for her to have a vibrator up her snatch?" Ray asked Polly.

"Oh, absolutely," Polly groaned in annoyance, "Ever since we were teenagers, she's always found a way to sneak one in there when no one was looking. Eventually we just gave up trying to stop her."

"What can I say?" Paula moaned, squirming in her seat, "A girl has needs. Mine are just... oh fuck... stronger than others."

"That is a gross understatement," Polly said to her sister, "Emphasis on the gross."

"Oh come on," Leo said to her, "You don't find it that disgusting, do you?"

"No, not really," Polly said with a sigh, "I'm used to it by now. It's just embarrassing when her little habit comes up in public."

"That must happen a lot," Ray said, before turning back to Paula and adding, "I mean, with that much stimulation on a regular basis, your pussy must be constantly soaked and dripping. Isn't that right Paula?"

The smell of Paula's sex suddenly filled the air, and the buzzing grew louder.

"Yes, it is," Paula said, reaching down between her legs to pump the now unobstructed vibrator between her legs, which added a light squelching to her sexual chorus, "I usually can't even wear pants or panties without ruining them. Oh God, I'm getting close..."

"To cumming?" Ray asked.

"Mmmhmmm," Paula moaned, biting her lower lip as her squirming intensified.

Ray got a wicked glint in his eye as he asked, "But don't you need Polly's permission in order to have an orgasm?"

"Fuck, you're right," Paula panted with a frustrated look on her face, "I don't know how you knew that, but you're right."

She turned to her twin sister and begged, "Polly, please, please let me cum, I'm begging you please, I need to cum, please..."

Knowing an opportunity when he saw one, Leo preempted Polly's response by asking the girl, "You aren't seriously going to let her cum during our date, are you?"

"No way," Polly exclaimed with a scowl, "It's her own damn fault for wearing the vibrator in the first place. Maybe being pent-up here in front of you two will teach her a lesson, though I doubt it."

Paula groaned in frustration and sunk further into her chair, "Dammit Polly, I'm so clooooooooose..."

"And you'll stay that way until we're done here. Quit whining about it and maybe I'll let you cum in the bathroom before we leave."

Paula sulked in defeat and sat back up, doing her best to keep the vibrator from falling out of her slick pussy as she did so. Leo looked over at Ray, who was grinning like a maniac at all of this. No words needed to be exchanged between them, because it was obvious he was thinking the same thing Leo was: this was awesome.
