No, you're safe here, at least. If you crawled out, there is danger, so to maximise your survival chances you need to stay here.
Here, in the warm, dark embrace of Dahlia, dominated by every breath of her lungs, every pulse of her heartbeat. It's a miracle you can get to sleep at all, your first tiny night held in the clutches of a giant captor, your mission already failed...
You jump up, running from the form behind you, the possessive giantess yawning and looking around for her pet. The rumbling of her footsteps follow you as you tear through the house, dashing as fast as you can and tossing furniture behind you, every obstacle buying you a moment.
Finally you slam the front door closed behind you, leaning your weight against it as you catch your breath. But you have stepped onto skin, and look up to see that you stand in Dahlia's hand, and she smiles before she opens her mouth and moves down to swallow you whole -
You wake in a sweat, still within the hand of a giantess, but one is not intent upon devouring you. Instead, you hear the roar of Dahlia yawning, and flinch as one covering hand withdraws, the other clenching its fingers for a moment - a dreadful moment where you fear you'll be crushed!
But it opens, and Dahlia's face becomes your new ceiling, tired but smiling.
"You're real!" she laughs, and then her mouth is upon you, not devouring but pressing lips to you, your three-quarter inch tall body mashed against her palm by the unstoppable force of her kiss. "Ah though ah'd just dreamed you!" she says as she withdraws, her horrid morning breath washing over you. "Didja sleep well?"
You decide against telling her your nightmare, but then she laughs again, pressing her palm against her chest, catching you between two flesh walls in a crushing embrace. To her it may be a show of affection, but to you it's like being trapped in a softer car compactor, fearing annihilation!
She saves you with a sigh, withdrawing you at blinding speed and dropping you, shivering and sweating, onto her bedside table. "There'll be plenty of time for that later, ah reckon," she says as she stands, now dominating you with her height rather than her strength. "We've got all the time in the world."
The bedroom door opens without so much as a warning knock, and Mabel stands revealed, as majestic as ever. "That li'l guy okay, Dahl?" she drawls. "Time's ta feed 'im, girl. We's got a big day, decidin' what ta do with 'im. Now git dressed!"
"Uh, I'll take a shower first," Dahlia mumbles, ducking past her mother with towel in hand. Left alone with the more mature giantess, you shudder at what she may do now. Her eyes don't hold the same fascination as her daughter's, but she does have a slight smile playing over her face as she regards your tiny body.
Now may be your chance: one-on-one with an adult giant, you could put your case across, have a discussion, try and get treated like a human being!
