Before Sally could get an answer, the door opened, and as Cream zipped past and went into the house to start getting ready, Amy and Sally were met by some of the biggest breasts they'd ever seen in their lives. "Amy! It's so good to see you again!" Vanilla said with a cheerful titter. "And Princess Sally! It feels like it's been forever since I last saw you! I must say you've become a very mature young woman!"
"T-Thanks..." Sally was stunned. She remembered Vanilla being a fairly busty lady, but this was far beyond how her memories pictured her. Vanilla's breasts were so huge that they were wider than her whole torso by a significant margin. And she thought Amy was big. "It's uh...it's good to see you again Miss Vanilla. You look..."
"There's no need to worry your Highness, I understand that seeing me again after so long may have left you somewhat speechless."
"I'll say." Amy replied nonchalantly. "Looks like you've grown a whole cup size since I last visited!"
"More or less." Vanilla hummed in contentment.
