Isabella soon decided; she'd find someone who'd want to stay inside her boobs for the duration of the pool visit... Or, maybe longer. She wasn't quite sure yet. But who to start with? ...Ah, there's one of her friends, just laying back on a chair. "Hey there, Philippe."
"Hm? Oh, hello Isabella!" He sat up, smiling as he looks at his friend. "Heh, you're looking nice today."
"Thanks... Though, I'm not looking quite as nice as I want to be." She looked away, frowning.
"How so?"
"You can guess. You've been looking at them for the past minute."
"Hm?" Philippe blushed, then chuckled upon realizing what she wanted. "Ah, heh heh, you want to make your boobs bigger, huh?"
"Yes. I don't suppose you can climb inside them for the afternoon?"
At that, he seemed perplexed. "...Climb inside? Is that possible?"
"Should be. It's got openings, doesn't it?" She fussed with her top a bit, motioning for Philippe to follow.
The two decided to sneak behind the changing rooms, with Isabella removing her top, exposing her breasts. Philippe then... "What're you doing, Philippe?"
"Figured a little massage would make them easier to enter."
"Or you're just being a little pervert."
"...Um..."
Isabella chuckled, a laugh interrupted by a coo of pleasure. "Ooh, but that's what I like about you... Alright, I think that's enough."
Philippe stopped playing with his friends boobs, staring at them before bringing his hand to a nipple... And, surprising himself when it went right inside. "Whoa!"
"Ooh, that felt so good~!" Isabella moaned, "K-keep doing that~!"
"Heh, certainly." Philippe removed her hand, and decided to force himself headfirst into his friend's boobs, making her moan louder. She ended up grabbing his rear to push him in faster.
Eventually, she had him all the way in, her boobs having been enlarged from A- to D-cups. "Hoo, that felt good... You're not cramped, are you Philippe?"
"Are you kidding? This is great!" He began swimming around, making her chest bounce in her strained bikini top. "Heck, this is better than the actual pool!"
"Is it? Aw, thanks, Philippe." She gave her breast a pat before heading back towards the pool. She smiled from the increased attention she had now, all the eyes on her. Though, a part of her mused on what her friend had said... her breast was better than the actual pool? Maybe she should put more in there...
