Sarah gasped as she felt her body tingle. Robin looked over and asked, "What's the matter?"
"I feel w-weird," said Sarah. The tingling seemed to now be centered around her chest and her midsection.
Robin's eyes went wide. "Your boobs!"
Sarah looked down to see that the front of her sweatshirt was surging outwards. "Oh, my God!" she exclaimed. She put her hands over the two enlarging bulges -- it almost felt like balloons were slowly inflating beneath her clothes.
Everyone was staring at Sarah now, their mouths wide open. She let her hands drop once the growth seemed to have stopped -- and her hands found that her hips had gotten bigger as well. She moved her hands backward, and discovered that she now had the firm, rounded ass she'd always dreamed of.
Paul broke the silence. "Holy shit."
Samantha said, "Girl, you're hot!"
"Wow," stated Adam, his mouth still wide open. "Why would our host not want us to press the button?"
"Maybe that's what the party is for," suggested Samantha. "Maybe Bob wanted to show us this magical device he built, or found, or whatever."
"Or maybe he wants to keep it all to himself," said Robin. She turned to her date Adam. "What do you think?"
Adam, of course, hoped Robin would gain a voluptuous figure just as Sarah had. But, trying to be diplomatic, he said, "I don't know. Maybe we should wait for --"
"Too late!" said Robin. She slapped the big red button.
