Lavella, a giantess lamia, brings home a wriggling bag of human-sized "gifts" for the resident mare monster girls. Will she win over the giantesses, while she puts on a show of swallowing her tiny-sized "treat"?


Author's note:

The "monster girls" in these stories appear physically human-like with animal features, such as ears, tails and so on. The lamia girl is designed similar to a naga (see myths for more detail on lamia specifically). They are often giantesses of various heights, which will be noted. Enjoy!

“Cookie” for Santa’s Helper


Written by Arian Mabe (Amethyst Mare)

Commissioned by anonymous

Lavella, a lamia girl, slithered into the mansion with a brown sack slung over her shoulder. Her human half, roughly proportioned for that of a forty-foot-tall giantess, was clad only in a scanty red, latex bra-top with white fluff around the edges, though she’d only donned that as she was trying to sway the mare girls staying with them. Lavella’s snake tail, however, stretched out and out from the point of her hips, spanning an easy one-hundred-and-sixty-feet. Her pale scales attracted attention, though Lavella rather enjoyed her new look with her hair dyed black.

A black outfit would have suited her better, though she was told “red” was the colour of the Christmas season some humans celebrated. To the giantess, it just seemed like another excuse for them to party and enjoy themselves – which was not entirely a bad thing. She was just a little more careful with alcohol after a dreadful day after her first time being intoxicated, though the “hunt” for drunken victims that night had also been fruitful.

The rules on that planet were silly, but the monster girl was willing to play along as long as she filled her belly – and her need for domination too.

However, there were some guests in the mansion she wanted to win over… Not for any particular reason, really, but more to see what if she could. It was becoming annoying how they scurried away and eyed her warily whenever she was around. It wasn’t as if he was hungry enough to eat the mare girls, after all, or stuff any of them into her serpent pussy…

Not yet, at least.

“Hm… Ho-ho-ho!”

The lamia girl smirked and rose higher on the coils of her serpent body, half-turning her body in the living area of the mansion so the other giantesses could see the wriggling back she had with her. Muffled cries echoed from the bag and Lavella grinned more widely, more than pleased with her haul.

“Santa’s helper thought you girls would like some treats,” Lavella hissed, though her tone was lighter than usual, laying on the charm. “A goodwill gesture… And I heard you like gifts.”

The mare girls leapt up, the herd all clustering in to the table where Lavella upended the sack, dumping out a pile of drunk humans. Some were in various stages of undress while others were naked and a couple still had their clothes on: either way, they’d all agreed to go with the lamia and intoxicated enough that the law would turn a blind eye to their disappearance.

“Oooh… Well, you do know your way to our hearts then,” Vera murmured, her red-brown ears flicking back and forth through her hair, a grin tugging at her lips. “Or maybe our stomachs.”

Lavella laughed aloud.

“I can’t deny that… I prefer something larger to fill my belly, but there’s uses for many, especially tinies.”

Her friend had shown her, in fact, that a tiny like a human could do a lot more than she had anticipated before, which was a very good thing. Opening up fresh avenues of sexual pleasure was always something Lavella was keen to explore, now that she was in a position to do so.

The mare girls chorused their thanks, seeming to relax a little more in the lamia’s presence, although Lavella wanted one more thing from them.

“I think Santa’s helper deserves a cookie for bringing you all these delightful gifts,” she said, stopping the mare girls before they enjoyed her bounty. “Mmm… Cookie!”

The mare girls blinked at her for a moment, wondering what the predatory giantess wanted from them – though it all became clear in but a moment. Amongst the humans staggering and wobbling on the table, all trying to get up and work out where they were, a lone elf stumbled out of the crowd. With a green hat on with a red trim, a bell jingled from the tip and she tottered with her hands in the air.

“I…am Cookie!”

She grinned foolishly, her smile too wide and showing off too many teeth, though the elf didn’t seem to know, truly, what she’d got herself into. She was only the size of a human, roughly five-foot-six, but that wasn’t going to matter to the lamia girl as she enjoyed her “cookie.”

Nussa’s lips broke into a grin as she watched the lamia take her “cookie,” picking the tiny elf up by one arm and letting her dangle. The bell on her hat jangled musically, though Lavella hissed and removed it swiftly, preferring to devour her food without any clothing when possible. Clothing was simply more difficult to digest, though she was not at all against savouring a clothed meal either, if the opportunity presented itself to her.

“Mmmm…”

Lavella tipped her head back, sinking a little lower so the mare girls could enjoy the view – for enjoying gifts like that was very much something they all had in common there. There mare girls just had to get used to her, for she was no longer quite the threat they had been when they had lived through the portal closer to one another. Her tongue slipped by her lip as she opened her mouth wider and wider, showing off her lamia features as the folds of skin hidden in her cheeks strained and opened up, letting her open her mouth much further apart than other monster girls.

The elf dangled from one arm, swinging back and forth, completely unaware of what was happening. Cookie giggled, the elf naked, for she hadn’t been wearing anything besides the hat.

“Ooohhhh…” She laughed, looking down into the soft pink of the lamia girl’s mouth, though her view of it was rather fuzzy, catching the light glinting faintly off the inside of her increasingly gaping mouth. “What a pretty mouth…”

Rhonwen cheekily slid a glass of minotauress milk from their resident minotaur monster girl across the table, some of the drunk humans blinking up at it, for it was taller than any of them. Lavella paused, her longer tongue slowly extending, though she had only started to unhinge her jaws for show.

“Humans take their cookies with milk,” she said helpfully, though the mare girl, who seemed to be coming a little more out of her shell, didn’t keep her lips from stretching into a flirty smile. “Just to wash it all down.”

Lavella chuckled lightly and fully unhinged her jaw, letting her mouth open to its widest extent, even though that was massively overkill for eating a tiny. However, she tipped her head forward again, after showing off what she could do, a glint in the predatory giantess’ eye.

She did enjoy playing to an audience in a way she had not been at liberty to do in, well…years.

So, she dropped the elf – but not straight down her throat. Cookie landed on her tongue and bounced there as Lavella withdrawing her tongue fully into her mouth, yet the lamia girl kept her jaws parted more than enough to show the others what was going on in there.

“Mmmm…” She murmured, a hiss winding through her tone. “What a delicious cookie…”

She was barely even playing the part of Santa’s helper anymore, though the mare girls hung on her every word, jostling one another to get the best view. Yet the lamia girl’s tongue wound around the elf as she toyed with her, pushing her to the front of her mouth and then scooping her into the depths once again. Cookie squeaked, her entire body slick with saliva, though Lavella slurped softly around her, enjoying the almost fruity flavour. It was as if the small elf had rubbed something sweet into her skin just for her.

Or maybe that was just how Cookie tasted naturally. It was not as if Lavella was going to ask after that, merely enjoying the moment as she slurped around her, languishing softly in the moment. There was an art to savouring prey and she was very aware of the mare girls staring at her tits, her throat, even some of their eyes going down to her two separate sexes. Of course, the snake part could be fully closed and hidden, but she’d cast off the loose skirt she’d been wearing out the moment she was back within the grounds of the mansion. Decency wasn’t something Lavella had ever been all that concerned with.

“Oof… Mmm!”

The elf murmured within Lavella’s mouth, though all she knew was that she was warm, sliding back and forth on a surface that moved under her. The lamia girl’s tongue swept up and around her, tipping her head down to the back of Lavella’s throat, though the lamia girl wasn’t one for toying with her food for too long. It was more entertaining, after all, when she was being watched.

“Go on, Lavella,” Nussa urged her, taking the lead for the rest of the mare girls. “We can’t have our gifts until you have your cookie!”

She was quick enough to play along, enjoying the twisting of the human traditions for their own means. The lamia girl shivered, a ripple running through her body. That was enticing and, for a moment, Nussa felt a little warmer towards her.

After all, they couldn’t be scared of the predatory monster girl forever – not when they were all in the mansion to look after each other, given a place to rest by their mutual friend. Maybe they could all be friends too?

Lavella took the moment in hand, letting the mares all see the elf on her tongue, which very lightly extended past her lower lip alone – just the tip. There was no other fate for Cookie as she grasped the glass of minotauress milk and poured it, without ceremony, into her mouth.

With a loud, wet gulp, she swallowed it all down, the swill of milk sending the elf straight down her throat. There might have been a squeal to be heard in the wake of the elf, though no one was there to pay attention to that.

Down and down and down the lamia girl’s throat, the elf plummeted. She gasped, milk pouring around her, though the soft plop down into the lamia girl’s belly was not one she recognised. For a moment, she floated on a thin layer of milk before it all spread out within Lavella’s stomach, though she was not aware of her fate and the direness of her situation.

She shouldn’t have got as drunk as she had around the lamia girl, but that wasn’t really a choice she could take back, in hindsight.

With Cookie swallowed, the mare girls cheered and pounced on the gifts, some of them shoving the humans straight into their mouths while others hugged them to their bare tits. No two mare girls in the herd were the same, after all, and Nussa took two gifts at once, pushing the humans together between her lips as her ears twitched in obvious, open pleasure.

“Mmm… Maybe we can come to like you, Lavella,” she teased lightly, though, in all fairness, gifts went a long way with mare girls. “Maybe.”

The lamia girl grinned, though didn’t partake in eating any of the humans: they were for the mare girls alone.

“It’s a pleasure to see you enjoying so much.”

More than Lavella could honestly put into words as she watched Aleah, a sixty-nine-foot-tall monster girl suck on a human in her mouth. She left the human’s head and breasts protruding from her lips, but the human moaned deliriously, the mare girl’s tongue doing wonderful things to her lower body. The moment was not about the tiny’s pleasure, however, but Aleah’s, her dun ears twitching while she tipped her head back slowly.

Lavella tracked the gulp and the bulge of the human going down her throat, though the mare girl ran her hand down her front at the same time, following the path of her gift. All gifts, after all, ended up in the same place and there was no mare girl there who would not secure their gift safely away in their belly when they were done toying with them.

She grinned.

Maybe she’d be giving the mare girls even more gifts, just to watch them enjoy…
