Need some support...

We searched through Sandra's clothes for something that would hold our massive new breasts in place, but there wasn't much. Sanra found a stretchy old sports bra that just barely held hers in, but for me, there didn't seem to be anything.
"I can't even get my cheer top back on," I said, looking at the bundle of fabric that flatly refused to go over my chest.
"Wait, I think I have something..." she said, then she started digging in her closet. She came back with something black and satiny that I'd never seen before. "It's left over from a play I was in last year. It's spandex and stretchy, so it should hold those in place." I took it and looked at it. It looked like a bathing suit, but it had clasps at the bottom, and stretchy bra cups. With Sandra's help, I got into it, and slipped my big breasts into the cups. The straps stretched out too much and my big boobs almost fell right out, but Sandra helped me adjust them. They barely stayed in place as I slipped a sweater on.
"What happened to us?" she asked.
"Um..." I said, "Like, maybe we got our wishes." I found the wishing rock on the floor and stuck it in my clothes pile. With the big sweater and my tiny skirt, I felt a little weird.
"Well... maybe I can tell my parents it was a growth spurt. What about you?" she asked.
"I dunno," I said. "But hey, this means we can go shopping for new clothes!" The scary thing was, I actually was excited about getting new clothes. She looked at me like I was crazy then started laughing. "Jonnie, if you weren't so amazingly hot... Yeah, we need some new clothes."
I giggled with excitement and hugged Sandra. Our massive breasts collided in a pleasant way.
