"Um, that's okay, er, Miss. I believe you." you stutter, marvelling at her perfect body.
"No, no, I really don't mind." she says, growing another few inches, causing a button to pop off her shirt. "Besides, growing is fun!" she continues, growing a little more. You feel slightly ashamed of all the skin you are seeing of your friend's mother, even if she is smoking hot.
"Seriously, a demonstration really isn't needed." you say nervously. Nonetheless, she carries on growing. Her shirt rips open, revealing a flat stomach, a curvy torso and the best, most enormous breasts you have ever seen in your whole life. They make Suzy's look like peanuts, you decide. To your embarassement, a hard-on quickly forms in your pants as her jeans rip, revealing absolutely perfect legs.

"I hate to sound rude or pervy, but are your, uh, assets, natural?" you ask nervously.
"Yup," replies Laura, "these L-cups are utterly 100% natural. I think they're the world's largest natural breasts, but I rarely go out so the media doesn't know."
"That's, um, fascinating." you reply, still stunned by the beauty before you. And just then, all at once, her head breaks through the ceiling and her underwear all snaps of with a twang, leaving her naked. Your jaw literally drops at this new sight.
"So then, Anthony..."
