Becca took the green bottle of Bombshell Classic, drew a deep breath, and prepared to drink it.
"Wait!" said Min, her eyes flashing with excitement. "Let's try one of the other ones!"
Real fear crossed Becca's eyes. "Min, we don't know what they can do! What if it turns me inside out, or it turns me into a ferret?"
"I don't think they're meant to be harmful," Min said. "And if you get turned into a ferret you'd be the first human to experience that. Think about it. I know you don't like to take risks, but here is your chance to make history."
"I don't know..."
"I'll let you play in my cleavage, ferret-girl."
That drew a laugh from Becca. "You know what? I'll do it. Give me a bottle from the cooler before I change my mind." Min handed her an opaque white bottle. Becca unscrewed it and gave an experimental sniff. "Smells like coconut. Well...down the hatch."
To Min's delight, she nearly finished the bottle in one long chug. Almost immediately, the green in Becca's hair faded, replaced by pure white. Becca did not seem to gain any height, but her breasts began to swell immediately. Her beloved Princess Bride shirt strained and gave way as twin mountains of titflesh burst through. They settled somewhere around an H-cup. The white soda clearly had the same arousal effects, and Min watched with lust as Becca writhed in pleasure, even stroking her pussy through her shorts.
"You want help?" Min asked.
"Maybe?" Becca gasped. "Almost there...so close...can't seem to...oh, it's happening again!" A second wave of growth surged through Becca. Her breasts grew even bigger, her swollen nipples standing out the size of the bottle's screw-cap. Tentatively, Min reached out and touched one.
Becca cried out. The intensity of the pleasure was overwhelming. She needed release, but she couldn't bring herself there.
"Becca, you're leaking," Min observed. Sure enough, a creamy white liquid was emerging from Becca's nipple and trickling over Mins hand.
"Min...help me. Please," Becca begged. This was all the invitation Min needed. She latched on to Becca's breast and began to suck, drinking the milk in greedy gulps.
Almost immediately, Becca had the most intense orgasm of her life. The feeling was so intense that she almost laughed with joy as she came. The feeling of pressure on her breasts subsided, and she enjoyed a series of similar orgasms as Min finally drank her fill.
"That was intense," both girls said, nearly in unison, as they flopped onto the pool deck. Becca's breasts had stopped swelling and had returned to their H-cup starting position. Despite their size, they stood out proudly from her chest, and Becca speculated that she could even get away with going braless. Then she noticed something.
"Min! You're bigger!" Becca said. Sure enough, Mins breasts had increased a cup size, and she stood several inches taller than before.
Min was delighted. "This is great! You're like a soda machine," she laughed. She tore off what remained of her tank top and exposed her tits to the world. "Won't be needing this anymore. Care to join me for a swim?"
"Only if we fool around while doing it," Becca said coyly. She realized that she didn't have a single regret, and she practically pounced on Min once they were both in the water.
