Changed into lingerie

Vanessa entered the changing booth where Lauren nervously waited. Vanessa quickly set about undressing her: She tugged off the dorky shorts, kicked off Lauren's shoes, yanked down her panties. When Vanessa undid the girdle over Lauren's chest, Lauren breathed a sigh of relief, able to breath better. Then, to her total flustered shock her sister grabbed at one of her mini breasts and smooshed it flat down with her fingertips.

"Ah! Ow!" Lauren yelped in shock and discomfort. Ignoring her, Vanessa then stuck a piece of breast tape over Lauren's squished down breast. She repeated the process for the next one.

Lauren looked down in shock. Her small breasts were smothered and restricted by the small tape over each breast. It had the same result as the girdle she'd been forced to wear, but much more discreetly. While Lauren looked down in horror, Vanessa forced her to step into the white thong and tugged it up. Lauren yelped as the string of white fabric consumed between her massive meaty cheeks. Then Vanessa slipped on the teddy. The fuzzy cups of it hid the tape over Lauren's breasts, though it was clear the cups were empty, with space showing between to make it plain Lauren had no breasts to speak of. Only a careful eye looking down into the half empty cup would even see the tape restricting down her nipples. The sheer fabric of the teddy did nothing to hide her belly or any of her other features.
