"Mmph, s-sure, I'm fine with sleeping with you."
"Wonderful!" Delighted by you agreeing, Opal pulled you and Isabelle into a hug, compressing you between their combined boobs before pulling away. "You want to join us in the bed, Isabelle? There's plenty of room, snoot~"
Isabelle's face didn't take long to go as red as yours... before opening wide in a yawn. "U-um, I... a-as much as I'd like to, I-I've not had a proper sleep in my own bed for far too long. I-I'll be back in the morning to pick up the mayor, though. See you!"
"Sleep well, Isabelle!" Opal waved goodbye to your new secretary as she rushed out the door, and giggled at you as she walked further into her house, letting you take in the warm brouns and oranges of her imperial-styled home. "Man, you've already made a good impression on her, huh? Between you and me, it'll be nice to see her not run so ragged all the time anymore. I'm sure you'll be a great mayor, snoot."
"T-thanks, Opal... O-oh, uh, the name's Anon, by the way."
"A pleasure to meet you, Mayor Anon." She set you down on a low table at the foot of her wide bed, allowing you to take in just how massive she really was. Her hips, blanketed by lacy black panties, were right above your eye level, sitting beneath her massive white belly. Far above, you could see a large amount of underboob held up only by the front-tied black t-shirt she wore, jiggling a pleasing amount because of it. "Now, I've met with many a human before, but I think you're the first who I'll be asking this question."
"W-what question?"
"Where are you going to sleep, snoot~?" She shifted her hips slightly and smacked her ass, letting you watch it ripple across her fatty green thigh. "Only fair that all of me's open to the mayor... isn't there a rule about it?"
"The villager aid law," you commented, easily combing through memories of the documents you'd signed with a recollection spell.
"That's the one. And I'm sure getting someplace nice and snug will aid you greatly in getting comfortable with our town, snoo... ooooowwph... Oh, pardon me."
"Ymmph... y-you're fine," you reassured, stifling your own yawn—despite how tired Opal seemed to be, you had researched some spells that could lower your need for sleep if you wanted to. In fact, if you choose to sleep on or in Opal's body, you could use that to explore her while she herself slept... Heck, if you map out enough of her insides, you can use some enchantments to make her into a proper home for you! A nice place to stay during your (no-doubt long-lasting) tenure as mayor here in Giantopia.
After a few moments ponderance, you gave your answer: "Well, Opal, I'd like to sleep..."
