Rachnera and Kimihito decide to share a bottle of wine, unfortunately it seems neither of them can handle this particular wine. It makes them feel...strange, Rachnera starts feeling a bit...preyish, and Kimihito is feeling hungry.

Despite the thumbnail, rachnera is NOT the pred of this story

"Welcome home Honey." a silky seductive voice cooed as Kimihito Kurusu entered his home with several large bags of food that would unfortunately only last a week at most." Sitting at the table with her legs curled under herself was Rachnera, a woman that would terrify most people, but not him. The thing most people would notice first was that she was half spider, long black legs covered in carapace, six pupilless red eyes following the human as he made his way over to her. Her skin was an eerie pale white compared to Kimihito's darker skin, even more, contrasted by her skimpy black tube top and loincloth compared to his much more normal casual wear. An ominous skull pattern on her spider abdomen would no doubt give people the impression she was some scary criminal, but he knew better. Everything about her contrasted her warm playful nature that looked out for those she cared about, especially Kimihito. Kimihito by contrast looked completely average and normal, the only unique thing about his appearance was his short messy hair. However, that only served to hide his true nature, an unwaveringly kind man who cared for everyone, even those who had tried to hurt him something Rachnera knew firsthand, who never held a grudge. He seemed to radiate light and compassion. Rachnera adored that about him, when she had nowhere to go, been cast away by those she thought she could trust and lost all her faith in humans, he was there. Willing to open his arms to her, his home, who saw her not as a monster, not as a scary spider woman, not even as the woman who kidnapped him, but just Rachnera, his friend.
She playfully swished a paper coffee cup at him as he placed the bags down with a warm smile. Her heart fluttered at his gentle smile.
"Honey, would you like to have a drink with me?" she cooed, pushing a bottle of wine over to the young man.
"It's from Miia's mother, don't worry about it being poisoned, Horseflesh was kind enough to test it. She seemed almost disappointed it wasn't poisoned, we might need to talk to her about spending less time with Mero." Rachnera beamed, her pointed teeth gleaming in the light.
"No thanks." Kimihto smiled as he pulled a mountain of frozen meat from one of the bags.
"Please? It's not as fun to drink alone, and it's rare I get to spend time with you alone." her voice quivered slightly as she spoke, he did have to admit, she had a point. Every time the girls and he did something, it was always as a group, and more often than not, Rachnera was excluded due to her introverted nature. This was a rare case where all the other girls were going to be away for a week or so. Papi and Suu were visiting the vampire Curie, Mero had been asked to return to the mermaid kingdom to cover for her mother while she was sick, Centaura was helping other centaurs, and Miia had been asked to stay at the shrine she worked at for a week due to a festival. For once, it was just the two of them. If it were any of the other girls he would have been a bit worried about her sneaking into his room, but Rachnera was nothing but gentle and understanding.
"Alright, but just one glass." he watched as Rachnera lit up hearing that he'd share a drink with him. She pulled the cap off the wine and excitedly poured him a glass as he finished putting the groceries away.
"I wonder what it tastes like. You know, I've never had alcohol before."
"Awe, I'm happy I get to be the one to see it first and share your first, even if my poison of choice is coffee." Rachnera chuckled.
"Well, it's not like I'll get drunk from just one glass." the two brought their cups together cheerfully "CHEERS."
One drink wouldn't be a big deal Kimihito thought as he brought the glass to his lips.

"And what's with this dou...doub..(HIC) double standard? A guy tries to rape a monster girl and people want his head, but a monster girl does it to a guy, and he's a lucky bastard? What happens if I try calling the police about monster girls trying to sexually assault me? They laugh and ask I need a tag in!" Kimihito bellowed as he knocked back his seventh glass of wine. Rachnera nodded as best she could, her head bobbing from side to side as she struggled to keep it straight.
"I'm sorry," Rachnera whined. "You don't deserve that."
"It's not your fault," Kimihito replied as he placed his now empty cup on the table.
"But it is! When we first met, I tied you up, tried to molest you and I didn't stop for the first month I was here. I kept trying to have my way with you every time you were alone." Rachnera sobbed. Her cool mature air evaporated, as she so cried into her drink. "And then I tied up Lala when she was helpless and in need of help. I tied her up and practiced knots on her when she was helpless and scared. I'm a horrible person." Rachnera's head slammed to the table with a whine.
"It's alright, you've grown a lot since you came here. Now you're the one I trust most to not try getting into my room while I'm asleep. Even Cera has tried a few times, even recently, but you haven't. And when the chips are down, and a problem pops up, you're the one who's most likely to get us out of it." the human smiled, reaching a hand out to stroke the arachne's head gently.
Rachnera shook her head weakly. "No, I'm not. I'm not that helpful. Why couldn't I have met you before? You're the amazing one, no matter who you meet or how horrible they look you treat us all like we're just normal people. Even if they kidnap you or try to hurt you, you just forgive them and offer them food. You didn't even join the homestay program by choice, that idiot Smith screwed up and threw Miia at you and expected you to care for her, and then just kept doing it. You had every right to throw all of us out, but you took us all in, cared for us, and treat us like part of the family. (HIC) you're the amazing one." Rachnera blubbered, a drunken smile mixing with tears as she spoke. "(HIC) What did I do to meet a human as nice as you?"
Kimihito barely held back his smile as the arachne rambled. "Well, I think you're amazing too. Smart, kind, cute, cool, sexy, gentle even if you do like tying people up, and, you give the best hugs." Rachnera let out a happy but embarrassed whine hearing his words. She reached a shaking hand over to the bottle of wine. She had switched from coffee to wine at some point, but neither of them could recall when or why. The two both poured the last of the bottle into their cups as they gleefully. The two brought their cups together with a cheer before swinging the contents down. Both could feel their heads spinning, their vision blurring, Kimihito couldn't help but look at the beautiful spider woman before him. Her creamy soft skin, the sweet smell that wafted from her, her loving red eyes, her soft breasts that he'd felt so many times, his mind began to wonder, filled with lust, but not in the normal way. He felt...hungry.
"Honey?" Rachnera's voice cooed, her body wobbling as she spoke. "I'm feeling something...strange." Kimihito didn't like the way she said that. Her eyes focusing on him intently, he watched nervously as she pushed herself up from the table, her arms wobbling for a moment as she did so. The clacking on the floor with every step of her armoured legs. Any other night neither of them would try anything they shouldn't, but tonight, with a bottle of strong wine shared between them? He couldn't help but gulp nervously as his mind flashed thoughts to him, including a one over and over of Rachnera bloating out his stomach. Her eyes gleamed excitedly as his timid gulp rang through the room, she picked up the pace, skittering over to him in an instant.
"Honey. Do you remember when we accidentally looked up vore?" she coed, her seductive whisper echoing through the human's ears.
"ye...yes" he rasped nervously.
He watched hesitantly as she leaned to his ear, "I don't know why, but I want you to swallow me whole. Every last centimetre of my body tucked inside you. Doesn't that sound fun Honey?" she whispered, the words sending shudders down his spine.

There was a long moment of silence as his mind raced, trying to deny how much he wanted to eat her, to feel her beautiful body in his stomach, to savour her creamy sweet skin as it slid down his throat. It was stupid, insane, ridiculous, there was no way he could swallow a single one of her elegant hands, let alone her massive body large than his own. But The thought of it made the young man quiver with excitement, even more, something told him he could do it. His mouth opened and closed wordlessly as he tried to find the right thing to say to stop what was happening in its tracks, unaware of his body moving on its own. Rachnera's armoured hand clasped in his own as he pulled it up to his mouth, her fingers slipping into his mouth. His taste buds exploded at the touch of her delicate digits, his tongue sliding across them, savouring her shockingly sweet exoskeleton. Her armour was cold, a sweet taste of vanilla radiating from her carapace. With her fingers in his mouth, his body wasted no time swallowing her entire hand in a single gulp. Rachnera's eyes gleamed at the sight of her hand in his mouth, the feeling of Kimihito's breath rushing across it sent shivers up her spine.
"There you go Honey," she coed between excited pants, "Don't I taste good? Don't worry, keep going. Her hand reached towards the human she loved so much. His mouth snapped open to engulf her other hand greedily. She could feel his tongue licking across every contour of her fingers, slipping under the plates of her carapace, his hot breath washing over them, and the way he lucked at her with lust, unlike anything she'd ever seen from him. It took all her will not to collapse to the ground in bliss.

The two stared at each other for what felt like an eternity. despite her desire to be in his stomach, Rachnera didn't want to force herself in. Every panting breath thundered off the walls in the silence.
GULP
The arachnee couldn't help but gasp in pleasure as her loving human swallowed, passing over the armoured hands to the soft supple flesh.
"That's it, Honey, just swallow me down. I'm not going to resist or make a fuss." Rachnera rasped, almost pleadingly.
Kimihito was all too happy to oblige, in truth it hadn't been a question of if. From the moment her fingers entered his mouth he knew despite all his willpower and resistance to sexual arousal, he had lost to his new hunger the moment he tasted her sweet digits. In moments he was inhaling her savoury elbows, no matter how hard he tried he couldn't stop himself from licking across her body. Despite her lethargic nature, there wasn't much fat on her body, what little there was only added to her wondrous creamy flavour. A slight hint of salt drew out her taste. He couldn't resist her, his hand gently but tightly pulling her head towards his ravenous mouth. Rachnera quivered under his touch, gazing in awe as his jaws parted to consume her.

Rachnera moaned as her beloved human engulfed more of her. Her shoulders slipping between his hungry lips with surprising ease, second by second more of her became food. Within what felt like mere moments Kimihito was reaching her jiggling soft boobs. If there was any part of her Rachnera was most excited to be eaten, it was her chest.
"Honey's seen my boobs too many times to count, but he's never really played with them before. He's always such a good boy who doesn't want to risk upsetting us, than again if it weren't for that stupid law he'd have probably lost his virginity a hundred times within the first month of us all moving in." she sniggered at the thought. "Miia and Centorea may have the honour of getting groped the most, but I'm the one who'll have the best experience soon."
The thought had barely finished before she felt Kimihitio's teeth sink softly into her breasts, not hard enough to hurt, but more than enough to send her body convulsing with pleasure. Kimihito Nearly leapt in panic as the arachne screamed suddenly, but his fear vanished as she squirmed with clear enjoyment.
"That's it, Honey, eat me, chew these amazing tits! Horse Flesh might have bigger boobs, but we both know mine are going to be perkier and more flavourful. Rachnera moaned, pressing her chest against his coarse tongue to encourage him. His tongue lashed across her erect nipples, forcing her tube top up with each feverish lick. Rachnera's legs twitched with pleasure, her mind fogging with blissful arousal.
"Yes! Eat me! Every last inch!" She begged. Kimihito's jaws slipped past the soft mounds, sucking on her trim belly before reaching her arachnid half. For the first time since his unexpected meal had begun he stopped to realize how impossible the next part of his meal would be. How would he get her lower half in? Her second abdomen was larger than his entire torso, each of her legs was almost as long as he was tall. Her lower half alone was almost as large as his entire body. But he'd already come too far to give up, Rachnera was pleading him to devour her, to finish eating her, and he had no intention of letting her down.

He reached forward to try pushing Rachnera's legs into a curl.
"If I can just move her legs, I think I can get her in." His fingers brushed across her just out of reach knee. The leg bucked at the brush, shooting forward and tearing the leg from the table sending it crashing to the floor. Kimihito trembled in fear at the sudden reminder of both how powerful Rachnera's legs were and how sharp they were, they were. To his relief, Rachnera must have realized what he was trying to do as her legs curled under her body. With the hurdle of her tantalizing legs handled Kimihito redoubled his attempt to consume the monster girl. His lips passed over her hips, beginning his way down her widening body. Gulp after hard gulp he moved over the smooth armoured body, despite the cold hard texture every part of her exoskeleton exuded sweetness, he couldn't help but lick across the slick natural armour. He could feel Rachnera buck and quiver inside his throat and stomach, hear her faint cute moans as she sunk deeper into him. His teeth scraped across her carapace, dragging gently across her until even her spinneret slipped between his lips.

BUUUURP
the human let out a belch that thundered through the kitchen, even shaking one of the cupboards open.
"Sorry, Rachnera. That must have been hard on the ears. Are you alright?" he called, gently stroking a round bulge her human half left in his gargantuan gut.
"Alright? I feel great! And it doesn't hurt that you're groping my boob right now." Rachnera laughed, Kimihito's hand shot away with a frantic apology, "It feels great in here Honey. I don't really know what compelled me to do this, but it was a great idea, and given all that licking, I think you had fun too." she coed lovingly.
"I did. It was hard, but you tasted amazing, and feeling you inside my stomach is..." he tried to think of how best to describe it, but no comparison or conveyed how good it felt to him. "You feel wonderful Rachnera." he hugged his massive belly with a warm smile the arachne could feel even through the layer of bloated flesh.
"Good. After all the food you cook for us, it seems only right that I make a nice home-cooked meal for you for once. I'm glad you enjoyed it. It was made with lots of love." Rachnera teased, playfully pressing her head against the wall of the stomach so he could tell where she was.
"Awe. Thanks, Rachnera. I love you too. But I think I'm going to take a nap now." the human yawned, a gentle loving hand caressing his willing meal.
"We should try this again at some point," Rachnera mumbled, the only reply was a loud snore from her beloved human. She shrugged and began to spin a web, skillfully forming the silk into a blanket.
"Sleep well, Honey." Rachnera coed as her eyes closed. She had almost drifted off to sleep as a thought crept its way in.
"Wait, do I need to worry about being digested? Ah, whatever. If I do I get to be part of Honey. That's a good way to go." she mumbled before drifting off to sleep in the stomach of the person she loved most.

"You drugged us! Again!" Kimihito yelled into his phone. A woman's silky voice on the other end chuckled before replying.
"And?"
"You drugged us again! You sent us a bottle of wine and drugged it! Why?" the human snapped.
"Well, I had to get you to act somehow. And getting you and whoever you shared it with horny and hungry was a good way to do it. Though I'm a bit sad to hear it wasn't with Miia. No matter. So, how is the spider doing?" the voice giggled unfazed by his anger.
"Rachnera is safe for now, but who knows how long that will last. How do I get her out!?"
"I know. Don't worry, she can be in your stomach for two months before any negative effects start. I already sent another batch to you so it should be there in a week or two. Depending on the postal service."
"Why are you sending me more!?" Kimihito had to hold back a frustrated cry.
"Well, you want to let her out. You can't do that without more. Drink about half the bottle, it'll kick in and you'll be able to spit her out no problem. Well, one problem. You'll be pretty hungry after she comes out so be sure to have one of the girls around to feed you when she's out."
"You want to replace her with someone else?" the human snarled.
"Whaaaat...nooo. I mean to feed you purely normal food...what would make you think I want you to go around eating your harem? Anyway, the medicine should be there soonish. The postal service always stops stuff I send. They think I'm some nefarious villain sending drugs and poisons."
"You are! You just admitted you were sending drugged wine!"
"Medicine!. It's a dietary aid, it slows digestion, helps curb hunger and you still get the calories you need without any of the fat. It's not my fault it has side effects on humans that makes them vorny. By the way, tell Miia Mommy says hi. Bye Darling." she teased. Before he could say anything the call ended.
"It's not a big deal Honey. Honestly, it feels great in here, I don't mind staying in here for a week or two. Besides, we both know none of the others would mind either." Rachnera's words sent Kimihito's massive belly jiggling, the mountain of flesh bigger than his entire body.
"I know, that's part of what scares me."
