Takes her sister's top

"No wait, Lauren stop!" Vanessa whined as Lauren grasped the hem of her sister's shirt. With a small wink at Vanessa Lauren hoisted the shirt over Vanessa's head, causing some comical flailing as it was slipped off Vanessa's arms.

The shirt slid off, revealing Vanessa's thick white bra. Vanessa screeched and slapped her hands to her chest.

"Well, those look... alright." Lauren judged her underwear clad sister while everyone gathered laughed and snapped photos. "Maybe they look better without the bra."

"Lauren, don't you dare!" Vanessa yelped. Her now far stronger sister ignored her though, spun her around and unclipped her bra. She pried it off, exposing Vanessa's bare tits to the whole school!

There was an explosion of catcalls and laughter at Vanessa's exposure. Lauren moved to get a good look at Vanessa's breasts.

"Hmm... well, they're almost big..." She said. Actually Vanessa had full D cups. But, Lauren's were clearly larger, once more showing up her sister.

"But, they're so droopy!" Lauren commented. It was true: Vanessa's breasts were affected by gravity, hanging down slightly. Only Lauren's chest magically seemed to defy gravity.

"And those nipples! Or should I say napples!" Lauren laughed. It was true, Vanessa's nipples were pretty big. Not oversized, but very full.
