Serena giggles as Stella's rump enters her mouth, possibly the most embarrassing pose in which to be eaten. Her long, tentacle-like tongue snakes out of her mouth and begins to wrap itself around Stella, tasting her all over, yet respecting her privacy. After all, this was just a prank right now. Sure, she was eating the woman, but she didn't mean to rape her, too. Her mysterious underwater breathing system comes into play at this point so she doesn't need her mouth to breathe at all, allowing her to take as much time as she wants.
