Terrific story! Would love to see what other powers the pearl might have. If it can grow things, would be fun to see Mark and Abby grow back and finally think giant Cheryl is behind them and it's all over, but then Cheryl uses the pearl's growth power to grow into an 800 ft giantess and search the city for her little toys, Abby and Mark. Would be a lot of fun to see an actual giantess nympho! Also, either way, I'd love to see more bare footplay and cat and mouse games with Cheryl....she has the perfect attitude for a giantess,  and I love how much she comments on how tiny they are compared to her.  Great work!
