"That I," she kissed his neck, "will be gorgeous no matter what I weight, but my lovely king...you'll have to show you still love me."
"And how is that?" he asked as she moved downwards, trying to think through a raging erection.
"I want you to feed me," Nimidia teased him, standing up with a gymnastic leap and padding away, perfectly round rump swaying.
"I'm sorry, but feed you?" the King asked.
"Of course. If I'm going to get fat, we'll make it fun," the shapely fae said, moving her hands to cast a spell, "If I'm going to go from lithe and graceful to slow and heavy and placid and fat and gravid well...we'll do it with sex."
Plants burst out of the ground, forming a bush covered in heavy berries. Killian, tearing his eyes away from his wife's perfect legs, realized he'd never seen their like. They were bright purple, covered in white spots and about the size of a strawberry but perfectly round.
"What are those?" he asked, eyes twitching back to the heart shaped bulge of her ass.
"Meal-Berries. Each one has enough energy to get a grown man through hours of work," she smiled, leaning against a bench, tossing back her long mane of hair, "now feed them to me. Feed me until my belly isn't flat anymore. Feed me until we get a preview of when I get fat."
With little trepidation, the King picked up a berry and gently placed it into her mouth. Nimidia bit through it in a flash of white teeth, red juice running down her chin.She swallowed, licking her lips.
"Delicious. But I want more," she smiled, "fill your hands, but feed me one at a time."
Doing exactly what she'd told him had done pretty well so far for Killian, so he did as instructed. Nimidia ate slowly and erotically, moaning as she ate each bite. Her right hand was soon quite busy between her legs, stimulating herself as she ate and her eyes were closed tight. Killian watched enthralled, stopping only when he felt a very important area be grabbed tight.
"Have to make sure you enjoy it to," she smiled, fingers flexing, "the more you enjoy seeing me like this, the fatter I can get..."
Killian found it hard to concentrate between her hand and constantly getting more berries, but soon noticed that Nimidia stomach was starting to bulge. All those calorie heavy berries were packing up inside her, making her flat if not perfectly toned stomach begin to round out. Rather than slow down she became more voracious than ever as it advanced across her lap.
"Faster, faster," she said, beginning to sweat and pant.
He grabbed more berries only for her to abandon her hold and pull him to her. Killian's hard stomach was pressed tight against her swollen one and soon he found himself quite closely joined with her. Her legs wrapped around him, squeezing tighter as she climbed higher and higher...
Killian snored on the ground, a leaf getting closer and closer to his nose before he exhaled and blew it away. Nimidia looked down on his sleeping form, smiling at the hard muscles of his back and hips. Idly, she reached out to the bush she had grown and popped another meal berry into her mouth while rubbing her stomach.
She was young for a nymph and had never born a child, yet Nimidia was fairly sure her stomach couldn't be much bigger if she was at term. Normally flatish and hard, save for the little inch of softness near her naval, it was now well rounded, packed to the brim and starting to churn with absorbing calories. The Nymph gave a polite little belch as she rubbed the slope of her stomach.
"What will it feel like when this is permanent?" she asked herself, eating yet another berry.
