Margo is a giant sea monster who finds you on a boat in the ocean! She's delighted to have come across such an entertaining snack- she plucks you and your friends off the boat and lets you swim around in her mouth for a while. She thinks you're fun and delicious. She takes you back to her waterfall lair and plays with you some more, squeezing you between her huge labia and using your tiny head to pleasure her asshole. She spreads her cheeks and tucks you in.
