Katy didn’t plan to end up surrounded by horny girls in tight uniforms, but that’s exactly where she lands - a pristine academy that looks innocent until you realize every hallway hides someone’s dirty secret. She’s supposed to blend in, keep her little “extra” part a secret, but the game doesn’t really let you stay quiet for long. You start with harmless stuff - chatting, exploring the dorms, helping classmates with “projects” - and before you know it, someone’s bending over a desk, and you’re wondering if you should stop or push a little further. The writing’s cheeky in that way: it teases you, then drops you into something filthy before you can think twice. It’s not subtle, but it doesn’t need to be.

What makes it weirdly addictive is how casual everything feels. You’re just living a day, checking your phone, picking what to do next, and suddenly you’re watching two girls making out behind the gym while pretending to study. There’s a voyeur vibe, but also this trainer-like loop where you shape Katy’s reputation - saint, slut, or both. Sometimes it’s funny, sometimes it’s just hot. The corruption part sneaks up on you; one moment she’s shy, the next she’s spanking her roommate for “discipline practice.” It’s messy, inconsistent, and that’s what makes it feel alive. The sandbox part gives you freedom, but it also means you’ll waste time doing dumb stuff like walking across campus just to peek through a window. Worth it though.

The art? Yeah, the girls look good - soft skin, big tits, that glossy anime sheen that makes you stare too long. But it’s the little things that stick: the sound of a zipper, the blush when someone realizes what Katy’s packing, the way control slips away during a scene. It’s horny, sure, but also kind of funny how everyone pretends it’s normal. Maybe it is, in this place. Maybe that’s the point.

She’s the type of woman who walks into a lecture hall and the air just changes. Not because she’s loud - she doesn’t need to be. Her voice is low, deliberate, the kind that makes you lean in without realizing. Professor Reed doesn’t smile much, but when she does it’s never for you… until you start noticing that tiny hesitation in her tone when she calls your name. The game never rushes that tension; it lets it build and twist. Every talk in her office feels like a test you weren’t told about - intellectual, but charged as hell. The longer you stay in her orbit, the more it’s clear that she’s not as cold as she wants to be. That’s when the corruption starts creeping in, slow and almost polite at first.

There’s something really addictive about how it turns academic power games into foreplay. The writing doesn’t hold your hand - one minute you’re discussing ethics and the next you’re pulling her hair as she moans your name like it’s the only thing left she believes in. It’s not just sex scenes thrown at you (though yeah, there are plenty and they’re filthy). It’s the weird emotional rhythm between dominance and tenderness that makes everything hit harder. Her reactions - when she finally lets go, when the control slips - feel earned. Even the sandbox parts, where you can experiment a bit with how far you push her or yourself, somehow make the story more intimate instead of just checklist porn. You get to decide whether she’s your lover, your toy, or something in between.

And yeah, it’s graphic as fuck: messy titjobs that turn into handjobs that end in warm creampies on her perfect skin, moments of exhibitionism where she wants to be seen but hates that she wants it, and those rare flashes of romance that mess with your head more than any blowjob could. I found myself half turned on, half curious about how far she’d fall - or maybe how far I’d drag her down. It’s dirty, but not dumb about it. Like watching someone unbutton their soul, one button too late.

You wake up on this cold metal bed in a ship that hums like an old fridge and the first thing you notice is not the headache, not the missing memories, but that you are naked as fuck and someone hooked your body up like a toy. The game lets you decide pretty fast what that body even is, and it is not shy with options. You want a lean guy who gets pushed around and ends up on his knees? Go. You want a stacked futa with thick cock and tits that drip later when the drugs hit right? Also there. Female body with a dick, male body with a pussy, non-binary setup, whatever weird combo your furry brain cooked at 3 different tabs open on xVideos, it kind of lets you live that. Then the ship starts talking, crew starts showing up, and that whole “who am I” plot runs right next to “who the hell can I get to pin me to a console and breed me”. The crew is mostly guys, different vibes, some softer, some with that DILF energy where you just know they’ll pull your hair while telling you they’re doing this for your own good. It has that slow burn of corruption too, where early scenes are just teasing and “accidental” touching, then the choices pile up and suddenly you’re kneeling between two men, one in your mouth and one pressing at your ass, and you kind of know you walked yourself there step by step.

What I like is how it flips from talking about conspiracies and shady experiments into real filthy stuff without pausing to ask permission every time. One minute you are in some dark corridor snooping logs, next minute you got a hand around your throat, someone grinding your face against a bulge, and the text just spells it out. If you turn on the nastier kinks in the menu, the scenes get meaner, which I actually didn’t expect. I thought “oh nice, just more porn”, but then I hit a route where my character basically becomes a half willing slave for this calm older guy who keeps dosing you with some drug that makes you leak milk whenever he squeezes your tits. At first I was like, that’s too much, I’m just here for soft gay space romance, then there I am reading a scene where he fucks your ass on the captain chair, fingers your pussy or dick at the same time, orders you to keep eye contact while you cum and milk runs down your chest. It’s shameless. There’s humiliation edges too, like being made to clean up your own creampie with your tongue, or being passed around a small group while they comment on how tight you still are for “a well used toy”. It still tries to be funny sometimes, throws jokes in the middle of a blowjob, which kinda works and kinda ruins the mood, depends. One scene in the medbay has you strapped up for “exams” and the doctor uses toys first, slowly stretching you, talking about “data” like that explains why he has a vibrating plug with a remote, then he just goes in raw after your walls are gaping and you are begging half from embarrassment, half from need. There is also some interracial stuff later where they play with how “alien” bodies might feel, though right now most of them still look pretty human and I keep angrily waiting for real anthro options that will probably never come. Text based format actually helps here, your brain fills the gaps, so when they stack you for group sex, one cock in your mouth, one pounding your ass, one sliding into your pussy or between your thighs if you picked only one hole, it feels way more intense than some lazy clicker animation. You even get those small details, like fingers digging into your hips, someone groping your chest absentmindedly while talking business, a bored crewman getting a hand job in a storage room because he “caught” you snooping and decides you can pay with your hands instead of alarms. The game pretends it is all about choices and plot, and yes, there are combat bits and dialogs and moral stuff, but honestly the thing that sticks is that moment you realise you turned on almost every kink in the options and now your “lost in space” protagonist is on all fours in a locker room, ass dripping cum, balls or lips swollen, hearing boots stop behind them again and thinking “ok… maybe just one more”.

Japan in this game feels like someone took a horny sci fi reddit thread, fed it into ChatGPT on a bad day, then handed it to a very pervy writer with a school uniform fetish and a grudge. You land there as this kinda average 19-year-old dude, supposed to be an exchange student, pretending you care about classes while your brain is just full of your crush Julie’s tits and that tight ass she keeps pretending she doesn’t notice you staring at. Of course she brings her cute friend Alice, who acts like a good girl but gives you those tiny side glances that say “choke me a little, please.” On top of that, there is this whole mystery about Julie’s missing sister and a company that makes hyper realistic sex dolls, but half the time I kept forgetting about the plot because the game keeps throwing you in situations where you are either groping, being teased, or trying not to cum in your pants in some school hallway. The tone jumps around like crazy: one moment you flirt shyly in a classroom, next you are slapping a doll’s ass raw and making her call you master while your friend is in the next room. That mix actually works better than it should. It feels messy and dirty, in a good way.

The whole “Love Dolls” company thing is the part that stuck with me. Those dolls are basically walking sex toys with soft skin, big tits, big asses, and eyes that look a bit too human when you tell them to open their mouth wider and they just obey without question. They are made to be used, to be trained, to be humiliated. You can press them against a wall, pull their hair, force their legs apart, make them kneel on a cold floor and clean your dick with their tongue while you stare down like they’re nothing. There is this one scene where you are still acting like the innocent foreign student on the outside but behind a locked door you are pushing a doll face down on a school desk, fingers digging into her hips, pounding her so hard the animation actually sells the impact. Her tits bounce, her ass jiggles, she moans like a broken toy, and you know very well you are not supposed to be doing this in a place with textbooks and chalkboards. That mix of “I shouldn’t” and “I really, really will” is where the game shines. It goes from gentle teasing and soft kisses with your crush to rough anal with a doll chained to a bed, and the game barely blinks. You get moments of romance, then suddenly you’re strapping a toy to a girl, making her ride it until she’s shaking, and the MC is just watching with this fucked up curiosity like “what else can I do to her?” It’s not subtle, it’s not classy, and it absolutely doesn’t pretend to be. Which is kind of perfect for what it is.

This one starts gentle and then goes straight into the gutter, like a priest on Pornhub. You’re this quiet guy who grew up in an orphanage, no sex, no drama, nothing spicy, then suddenly you find out your dead father was running a pharma company that basically sells liquid corruption. The drug turns normal people into horny messes, submissive, addicted, hungry for more. Your stepmother Lucy is sitting on top of this thing like some evil nun with big tits and zero shame. She used it on you, broke you, tortured you, then threw you away like trash. You spend years training, obsessing, and then sneak back into the house as a security guard, pretending to be some random dude while you’re planning revenge and trying not to get a hard-on every ten minutes because everyone in that house looks like they escaped from a hentai tag list.

The sex goes from “almost normal romance” to “ok, that’s fucked up but I’m into it” step by step. Bridgett, your stepsister, is the soft spot. She actually feels like a person and not just a walking pair of tits. She’s sweet, a bit naive, and trying so hard to be good in a house where everyone is cheating, touching, lying, and sneaking around. When you start protecting her, it feels kinda wholesome at first. Then the game starts corrupting her with you. Slow groping in the hallway when no one sees. Accidentally brushing against her ass in the kitchen, not so accidental. A “comfort” hug where your hand slides a little lower than it should. There is this one moment when she’s crying in her room, you sit next to her to calm her down, and her head ends up on your lap, right on your dick, and she pretends not to notice. That scene felt way more dirty than straight-up anal, just because of the build-up. Later you get the more hardcore stuff, the oral, the creampie, the ahegao face when she finally snaps and begs for more. It actually feels like a corruption, not just a switch turning on.

Lucy is on the opposite side, full-on cruel milf energy. She uses the drug like a sex toy, like it’s just another thing in her drawer next to the vibrator. She talks down to you, calls you pathetic, then grabs your cock with this “I own you” attitude, and somehow you’re angry and horny at the same time. There is one scene where she forces you on your knees to “apologize properly,” and it’s basically a humiliation blowjob, with her hand choking the back of your head while she smiles like a saint in a stained glass window, except she’s got your cum on her tongue instead of a halo. The religion angle is very twisted here: there are crosses on the walls, family prayers, fake moral talk, and then five minutes later someone is getting fingered against the same wall. It hits that specific fetish where purity is just cosplay and everybody is rotten underneath.

The family itself is a walking harem waiting to happen. Cousins, step-something, everyone with big asses, big tits, too much makeup, and dangerous secrets. One cousin in particular clearly knows more about you than she admits. She flirts with you in this lazy “I know your real face” way, touching your thigh under the table during some polite family dinner. No big sex scene yet, just slow build, and honestly that teasing is hotter than half the actual anal scenes. Then later, under the excuse of “checking your uniform,” she corners you, runs her hand over your crotch, laughs when you get hard, and says something that sounds like blackmail and foreplay at the same time. The game loves this kind of domination where the woman is in control, but it still feels like you’re the one spreading the corruption, so the power keeps flipping and it’s messy in a good way. There is BDSM flavor too: cuffs, orders, forced positions, but it’s not super polished dungeon stuff, more like a very perverted rich family using whatever they want because nobody tells them no. You get masturbation scenes where the girls touch themselves thinking about you, handjobs where they test how far they can push you, anal in moments you don’t totally expect, and a lot of cheating that just happens in side rooms and corridors like it’s the most normal thing. It all fits the revenge story in a nasty way: the same drug they used to control and humiliate you, you start to turn against them, taking their fake holiness and grinding it into raw, dirty, shameless sex.

Gina is the kind of girl who makes you feel weak just by breathing near her. Thick arms, thick thighs, big soft everything, and still running around in tight sport gear like it’s nothing. You’re not some faceless ghost here, you are literally in her head, making choices, pushing her to grind in the gym or grind on somebody’s lap, sometimes both in same day. The whole town is like one big horny playground built around her body and her dad’s broken-down gym, full of people who either want to use her, worship her, or get crushed between those legs. And she actually starts kinda small at first, just strong and curvy, then every time you push another set, another deal, another fucked up favor, she grows. Arms thicker, ass bigger, abs more cut, expressions sluttier, moans louder. You start to memorize the way she groans when she hits that last rep. Yeah, I’m that kind of freak.

The best thing is how normal everything pretends to be at first. You just go around Burlingfort, talking to locals, doing small quests, fixing equipment, checking your phone like it’s a regular RPG life-sim. Then suddenly some stacked milf in yoga pants is offering “private stretching sessions” in the back room. Or the mafia guy shows up and basically says, pay up with money or with body. You think, ok, I’ll be a good girl, I’ll grind the sport events and training jobs, sell some supplements, right. Next thing, you’re arranging evening “work” in alleys and hotel rooms, still wearing your gym jacket while some rich bastard is smacking Gina’s huge ass and begging her to flex for him. And yeah, the game lets you decide: make her a loyal romantic dork who just wants one girl to kiss after sparring, or a full-on muscle goddess who fucks her way through half the city, sometimes with a collar around her neck, sometimes with a leash in her hand instead, stomping on people like they are her warm-up mats.

There are so many small moments that stick in the head. Like that scene where she first realizes she can literally lift a grown man with one arm during combat training, and the dialogue just quietly shifts from “fight” to “oh, you like that, don’t you?” while you’re still picking skills. Or the first time she walks into the locker room and sees another buff sporty girl in a tight uniform, and you get the choice between acting shy, acting cocky, or pinning her against the lockers and kissing her stupid. Or when she has to do a “special session” for money, and you can make her tease the client by flexing her biceps slowly while he’s already on his knees, then sit on his face until he’s begging her like some pathetic paypig. There’s humor all over it too, stupid jokes during serious scenes, ahegao faces when she’s supposed to be acting tough, random NPCs referencing stuff I’ve seen in meme pages on Reddit and Twitter. Sometimes it goes too far into the grind, like you’re running back and forth between gym and town again and again just to unlock one more pervy scene, but then she shows up in a new outfit, muscles pumped, tits barely contained, calling you a perv in that smug way, and yeah. I forget what I was complaining about.

Influencer girl from 2025, suddenly dropped into piss-soaked medieval mud and magic, is honestly one of those setups that sounds like a shitpost but actually works here. She goes from sponsored leggings and fake smiles to begging a cursed sorcerer in a crumbling tower not to feed her to demons, and the tone flip is hot as fuck. Lord Valthor is your POV, classic male protagonist, but written more like a fanfic villain route than a generic porn MC. You’re not “kind but misunderstood”. You’re a bastard with patience, magic, and way too much time to twist people, and the game leans into that. First hour, she’s bitchy, selfie-brained, trying to negotiate like this is a brand collaboration. A couple of scenes later she’s kneeling in cosplay armor you forced her to wear, cheeks flushed, pretending this is “just to stay safe” while your hand is on her throat and you’re making her stroke you between fights. That whole slow slide from brat to toy feels like reading an isekai corruption fic where someone actually cared about the pacing instead of rushing to the first creampie in five clicks.

Story wise, it really does that fanfic thing where canon is the obvious heroic route (save the kingdom, protect the girl, bla bla) and this game is the horny “what if the dark lord won and kept everyone as breeding stock” version. Old knights that should be your enemies end up fucked stupid by your bound harem in the war room. One of my favorite moments: after a tough combat sequence in the forest, you drag the exhausted influencer back by a magic leash, then use her mouth as a cheap reward while planning your next raid. She’s trying to keep her lipstick from smearing while a captured redhead priestess, already pregnant with your kid if you choose that path, watches from a cage and has to masturbate because of a curse linked to your orgasm. It’s cruel and silly and exactly the kind of scene someone would write in a “dark alt ending” on AO3 at 1% shame and 99% horny. There’s anal, boobjobs with those ridiculous big tits pressing together while you talk strategy like it’s normal, group sex when your harem gets too competitive over your attention, and one really nasty cheating scene where she has to fuck a rival lord on your orders while your mark on her body glows so she can’t cum unless you do. I kinda hated that one and also replayed it three times, so yeah. Combat actually matters more than I expected: win a fight, you get more slaves, more corruption options, more weird medieval cosplay outfits to stuff them into; lose, and some scenes shift into humiliation for you instead, which stings in a good way. I wish the time travel stuff went even harder, like more modern tech vs magic porn setups, but whatever, the mix of fantasy war, harem management, bdsm vibes and plain nasty male domination carries it. The animations and ai cg are sometimes uneven, a few faces look slightly off in certain angles, and yet when she’s riding you with that desperate “I don’t want to like this” expression while her big ass is bouncing and your hand is on her belly where your earlier load might be turning into pregnancy, it just works too well to care.

Abducted feels like someone grabbed a trashy torture porn comic, a cheap soap opera and a drunk BDSM club story from Reddit, then smashed them together and forgot to clean up the mess. You’re not “in” the story, you’re more like the asshole in the back row shouting what the girls should do, and the game actually listens. Six rich or important women wake up in this giant cage, collars, chains, confused faces, all that. No guys anywhere, which is kinda nice for once, just women doing fucked up shit to other women. The captives are panicking, half naked, trying to cover themselves, and the game suddenly throws you a choice like “How does she react? Fight back, cry, or pretend to be tough?” and you’re basically picking their personality on the fly while some dominatrix-looking psycho is already eyeing which one to string up first.

What sells it is how petty the captors are. They’re not calm masterminds, they’re bitchy, jealous, horny and a bit stupid, which makes the humiliation scenes feel more chaotic and dirty. One of them gets mad because a prisoner is “too pretty” and you can choose if she shaves her hair, whips her tits until they’re red, or forces her to lick the boots of the others while everyone laughs. Then in the next scene the same domme is masturbating in a corner because she’s turned on by her own cruelty and you’re like “ok you need therapy, girl” while still clicking the most fucked up option. You’ll have moments where two of the kidnapped girls are forced to make out, with the collar chain pulled tight, and you decide if it turns into sweet, hesitant kissing or if the captor pushes them all the way to rough pussy licking and ass play just to make them cry from shame. The switch from teasing to graphic violence is sometimes so fast it almost feels like a bug, but no, that’s just the tone.

There’s no protagonist “avatar” to hide behind, which is weirdly hot and also kind of uncomfortable, because every time you pick “yeah, let her get anal with that toy in front of the others, no lube” you know you did that, not some faceless hero. The game keeps jumping between the cage girls, the evil crew and the outside investigators, and sometimes the pacing is all over the place, like you’ll spend ages on one scene where a girl is forced to crawl naked over a floor wired to a teasing device that zaps her clit every few steps, with you deciding if she holds back her moans or just gives in and squirts while everybody mocks her, then suddenly cut to a brief interrogation where someone gets electro-tortured and it ends before it really escalates. There are routes where you can corrupt a shy captive into a broken little sub who begs for group sex from her tormentors, another where she stays proud and gets extra punishment, public oral, spit in her face, all that, and then there are endings where someone manages to twist the power dynamic and cheat her way into joining the abductors, trading her “friends” for a collar upgrade and a place in the gang. A lot of scenes are just still renders, so sometimes you stare at one girl in a gag for way too long and start noticing dumb details like one nipple ring clipping wrong, and it annoys you more than the actual torture does. But then the next choice pops up, asking if she chokes on pussy or ass first while the others watch, and you kind of forget you were mad.

A lich on the throne, a princess in chains, and you stuck in the middle like some horny middle manager of a dead kingdom. That is the whole mood here. You’re not a chosen hero, you’re the guy who helped the coup and now has to live with it while everyone around you tries to fuck you, kill you, or both in the same scene. The game runs in browser, VN style, but it doesn’t pretend to be classy. It’s all court politics, rotten magic and filth. One moment you’re negotiating with the undead king’s sexy fixer with her smug little smile and leather collar, next you’re in the dungeon “questioning” a rebel girl, and the choices are basically: be a bastard, be an even bigger bastard, or try to be decent and watch the world punish you for it. The writing is surprisingly sharp in that Eastern Euro fan-translated way where sometimes a line is awkward as hell but it hits harder because of that. There’s this scene where you visit a brothel that operates under the lich’s protection, and the madam talks about “patriotic holes” in such a dry tone I had to pause my browser and just stare at the screen.

Sex wise, it goes all over the place, and I mean that literally. Group scenes in candlelit halls with masked nobles using slaves like toys, rough groping in narrow corridors while guards pretend not to see, monster stuff in the catacombs where tentacled things treat clothes as a suggestion. There’s soft girl on girl moments too, especially around the princess if you steer her that way, with slow kissing and oral, but the game really likes humiliation and control. Tits fuck in chains, throat used like it’s just another hole, and the classic “kneel and open your mouth while we talk politics” thing that never really gets old. Some scenes are animated just enough to be dirty, not smooth, like those old Flash games we all pretended not to know, and somehow that fits. The BDSM has levels: sometimes it’s light bondage and teasing, sometimes it goes all the way into graphic torture mixed with sex that will absolutely not be for everyone, but the game does not stop to explain or apologize. There is one lesbian torture interrogation involving a captured resistance girl and a noblewoman that is written almost lovingly, then slips suddenly into real cruelty, and I honestly had to click through slower because it felt too real.

The morality stuff is where it sneaks up on you. You can play loyal dog to the lich, leaning into the corruption, whoring out prisoners, pimping citizens into prostitution to fund your schemes, basically turning the kingdom into a meat market. Or you can side with the resistance, which is not pure at all either. They use people, they push you into group orgies for “trust building”, they throw captured collaborators to monsters for entertainment. The princess is the weird center of it all, locked up but still dangerous. If you visit her cell enough, and push her buttons, she flips between broken submissive and manipulative brat, and there’s a route where she lets you fuck her through the bars while whispering about burning the whole city. I liked how the choices actually branch into different endings, not just color swaps. One run I ended as a half-mad mercenary fucking a demon on a pile of corpses, another I limped into a bittersweet “good” ending where the princess rules and I’m basically her private pet, chained on a cushion behind the throne in a golden collar. The game uses explicit violence and sex like a hammer, but sometimes it slips in a line like “you remember the faces of those you sold” and that hits harder than all the blood. Also, tiny thing, the auto-skip sometimes stops at random lines and it annoyed the hell out of me and I kept meaning to fix it in settings and never did.

Heavy metal sky, poison fog somewhere far under your feet, and you stuck on this floating rust bucket where everybody pretends they’re professional and noble until the lights go dim and belts come off. That’s the vibe here. You’re the new guy on the elite resource crew, supposed to be all serious with scanners and oxygen levels and “mission focus,” but half your brain is already thinking about that mechanic girl in the hangar who keeps “checking” your harness straps way too slow. On the surface it’s all sci-fi gear, suits, fancy tools, but between trips it turns into something closer to a porn hub search history that learned how to walk. You go from briefing room to blowjob in a storage closet faster than Discord goes from “hey guys” to full rule 34. Some of the scenes hit hard out of nowhere too. One moment you’re watching the airship drift through this neon green cloud, listening to some low hum like a chill lo-fi playlist, next moment you’re on your knees between someone’s thighs, hands tied to a pipe, feeling her thighs push your face deeper while she rides your mouth like it’s the last oxygen tank on the ship. The animation has this slightly off timing sometimes, which weirdly makes it feel more real, like when a horny cam model’s camera lags on Chaturbate and your brain just fills in the movement anyway.

What I liked is how the sex isn’t just “reward unlocked, congrats, here is generic pose number three.” There’s this scene after a rough mission where you stumble back to your bunk, sweating, gear still half on, and this older officer follows you in, locks the hatch, pushes you to sit, then just sinks down on your cock without a word. No slow fade, no speech, just this desperate grind. You feel the airship tilt a bit, alarms muffled in the background, and she clamps down on you right when some turbine roars outside. She rides you hard, nails digging into your shoulders, and when she makes you cum inside her, it doesn’t cut away. She just stays there, full of you, breathing heavy, one gloved hand on your chest, and you see your cum leak out slowly when she finally lifts off and tells you to “suit up again, hero.” That creampie shot with the light from a cracked porthole flickering over her skin honestly stuck in my head more than the big “story” moment before it. Funny thing, the UI color drives me crazy, by the way, this weird shade that looks like someone tried to copy Spotify in low light and failed. Anyway, the BDSM bits start almost playful then escalate, like the first time they strap you to that inspection table “for a safety scan” and suddenly the restraints tighten more than they need to. There’s a scene where they gag you with an air filter strap and use you until you’re basically just a toy, and at the same time the game pretends it’s still about keeping the city alive. It lies. This thing is about mouths full of cock in maintenance shafts, messy cream dripping onto cold metal floors, and that strange feeling when you’re hanging from a cable over the toxic fog thinking about how good it felt when the captain’s boot pressed between your shoulder blades while she rode you from behind and told you you’re just another resource to extract.
