The Djinn and the Giantess Cover

Kyra has it all figured out. Steal a load of artefacts, drain their magic and use it to make herself a buxom giantess. No more being bossed around, no more being passed over at the bar and no more A-cups!

She did not expect a Djinn to oppose her, however. Diana is more than capable of teaching Kyra a lesson about stealing—and she’s perfect happy to demonstrate how much better Kyra’s ill-gotten curves look on her own growing body.

Can Kyra escape with her stolen stature? Or will she be reduced to Diana’s sex toy, as the genie works out her decades of pent-up desire?  And how huge can Kyra become if she taps into Diana’s endless font of mana?

This 5.700 word story contains the following sexy themes: Lesbian, Giantess growth, expanding curves, size difference, squirting, edging, high fantasy, and dungeon delving.

The Djinn and the Giantess:
A Size-Stealing Expansion Fantasy

“Please. I have no interest in fighting someone as puny as you.” Kyra flicked Diana off her nipple, making her tumble down between her breasts, which she quickly pressed together to trap the snooty mage in a trap of tits. “Though I might enjoy smothering you.”

“That’s funny. I was about to say the same thing.”

Kyra opened her mouth to reply, but her words turned to a formless gasp as Diana abruptly appeared before her, growing straight out of Kyra’s cleavage at a speed that left her breathless. Before she knew what hit her, Diana laid on top of Kyra with a smug smile, every bit the giantess’ equal—except for her curves, where Kyra still dwarfed the other woman, her naked tits enveloping Diana’s chest completely. That only seemed to amuse Diana, who continued without missing a beat. “Want to fight me now?”

Kyra’s eyes widened. Instinct told her to back away, but there was no space; Diana’s thighs straddled her own, and moving her head simply met the cave wall behind her. “Not really?” She said somewhat more bluntly than intended, playing for time. What the hell were she?

“That suits me fine. I’m more of a lover than a fighter.” Diana pressed herself flat against Kyra, the tips of her fingers nimbly tracing along the curves of the black-eyed woman to feel up her fat, shapely boobs. “However, I do have a duty to punish you. Bound by my contract, I’m afraid. So as much as I’d like to keep fondling your breasts….” She pressed her mouth against Kyra’s, catching her gasp of surprise with her velvet lips and her wet, wriggly tongue, which managed to feel somehow far longer than it should have been inside Kyra’s mouth. And then, an intense flare of heat in her chest, a burst of tingly sensations that left Kyra’s nipples so sensitive that she nearly came from the skin contact alone.

Kyra moaned, flattening a score of smaller vaults with her shifting hips and legs. “Why are you…” she gasped, rubbing herself against her fellow giantess. The heat in her chest continued to build, a feeling that went straight to her clit, throbbing and pulsing and going mad without her touch. Something was wrong, but she was too horny to care. She let go, shuddering, falling behind in her dance with Diana’s wild tongue as her eyes rolled back in her head. “Ah, f—”

Diana pulled back, sly as ever as she finished her sentence. “... instead, I’m going to steal them.”

Kyra shuddered in orgasm, watching without understanding as Diana pushed herself up on her arms; she followed her gaze, staring at their tightly joined breasts. Diana’s rich, blue top marked the border between them, but that border quickly shifted, push down in a tug of war that Kyra realized, with mounting apprehension, that she could not win. Diana’s bust swelled obscenely, from flat to handfuls, handfuls to head-sized, and even beyond, enormous and arrogant. As Diana rose, Kyra fell; her proud breasts drained away, leaving her utterly dominated by Diana’s massive mammaries.

“W-what..?” she croaked, the transformation like a bucket of ice water against her face, denying her the orgasm that she was so edging towards.

“What, indeed? I thought you approved of stealing other people’s property? Did I mistake you for another giantess thief, Kyra?”

“No, I—Gods, just let me cum, and I’ll…”

“That’s what I thought. I don’t blame you, mind. These are rather nice.” Diana leaned forward, burying Kyra’s face in her boobs. “Go on, have a taste.”

Kyra accepted the fat nipple offered to her, suckling greedily when Diana rewarded her with a mirrored sensation upon her own. It was just the thing she needed to get over the edge; she attacked Diana’s tits with gusto, scrambling for that elusive climax. And yet, part of her was worried; smothered as she was, Diana was far more powerful than she could have imagined, and only seemed to get bigger on top of her. If only she could cum, she could think straight and figure out how to get away from this guardian with her spoils relatively intact…

Hot, wet juices squirted messily onto Kyra’s pelvis. Diana sat up with a big smile, purring contently. “Aah, that really hit the spot. You’ve got quite the tongue, Kyra.”

Kyra followed, desperately clinging to Diana’s boobs and the stimulation they brought her. “Just one more minute, I’m so close!”

But Diana eased her back, her touch gentle, but irresistible. “You’ll have your chance. If you manage to satisfy me. Who knows, I might even throw in a free wish.”

“A wish? You…” Kyra’s heart stopped. ”You’re a Djinn? Someone warded their vault with a fucking Djinn?”

Diana threw her braid back. “I know. Terrible waste, right? And terribly boring. I thought I might actually have died from boredom. But now,” she said, a terrible grin spreading on her face. “Now you’re here.”

Get out, get out, get out! Without so much as a witty reply, she dissolved herself into smoke, her titanic form melting away into the shadows clinging to the walls of the cavern, searching desperately for an exit.

Diana clicked her tongue. “Come now, Kyra dear. Is that really how you thank me for the chance to earn a wish?”

She found an exit and immediately pushed herself through the tiny slivers of open space around the door. There was a lot more of her than usual, so process was slow. It made her push all the harder, scrambling towards her freedom.

Only, freedom was rather more thigh-shaped than usual. Too late did she realize Diana’s ass waiting for her, the Djinn languidly seating herself on Kyra’s face as she materialized—back in the cavern, somehow, locked into her physical form with Diana’s wet slit grinding against her nose. “There we are, back on track. Bon appétit, little mana-eater.”
