This thing is basically a love letter to that old Demon Girl stuff, just with Derpixon brains spilled all over it. You get thrown right into this hellish dungeon vibe where the walls feel wet even though they’re not actually moving, and in the middle of all that is this tiny redhead demon chick who looks like she’s both in charge and completely fucked at the same time. I like that she looks playful and dangerous, but honestly sometimes her eyes are a bit too bright, like she knows she’s in a looped hentai animation and is kinda bored by it. The six scenes are all tentacle setups, but they’re not just copy paste. One moment you got a slime-like blob crawling slow over her belly, next it’s some ghostly limb going through her like she’s half spirit, half flesh. It’s messy, very cum focused, but actually not as gross as it sounds, more like someone spent way too long tweaking how the white stuff lands on her thighs.

What really got me was how the pacing is handled. You don’t just click and watch. The loops respond a bit to how you tap or hold, so you end up trying weird things just to see if something different happens. In one scene, I kept a slow rhythm, and the tentacles wrapped around her ankles tighter but her tail twitched like she’s pretending to be annoyed, while in another I spam clicked like a psycho and the whole thing escalated into this full body shake that honestly made me laugh more than anything. It’s horny and silly at the same time. Maybe it’s just me, but the way the ghost-creature penetrates her without “real” contact feels more pervy than the big heavy tentacles, like a haunted sex toy with attitude. The cumshots are very in your face, literally, sometimes almost too quick. You’re building up, and suddenly boom, finished, reload. It’s hot and also kind of like when Chrome crashes just as you’re about to hit the good part on a different site.

The audio is underrated here. I had Spotify low in the background at first, some synthwave playlist, and actually turned it off because the squishy sounds and her little half-choked moans were doing more work than the music. She doesn’t talk, no cheesy lines, only those breathy whimpers that sound like they were recorded by someone who was having too much fun. Still, one of the loops has this wet plopping noise that’s slightly off sync and now I can’t unhear it, like a bad TikTok edit, and it keeps pulling me out of the mood for one second every time. Visually, it’s polished as hell, and also kind of rough in tiny places if you stare too long at the edges of the slime. Hell backdrop glowing in red, tentacles sliding across her skin, ghosty shapes passing through her, that classic hentai finish exploding all over her horns and hair, it all sells the fantasy hard. If you ever watched those old viral “red demon girl vs tentacles” clips on sites you definitely shouldn’t open at work and wished there was a slightly more interactive, softer but still filthy version, this sits exactly in that weird sweet spot that shouldn’t exist but somehow does.

The game throws you straight into this weirdly cozy hellhouse where your “family” is too hot and too wrong at the same time. You’re the only guy in a place ruled by a demon mom who looks like she should be on some cursed porn magazine cover, and two sisters who are basically walking trouble. Story just moves on its own, no choices, no bullshit menus, you just click and watch things spiral out of control. It feels like reading a horny comic while someone keeps turning the pages for you. The mom comes off soft and gentle at first, but the more you see her, the more you realize she’s in charge of everything. She plays the caring MILF, hugs a bit too long, squeezes in too close on the couch, “accidentally” bends in front of you with those huge tits barely contained, then later she’s totally fine with using your cock like it belongs to her. The game doesn’t shy away from the whole taboo thing, it leans on it hard. She talks like she raised you and now wants to “claim” her reward, and it’s not subtle. Honestly they could have toned down the dialogue a bit, but it also made it kinda hot in a trashy way that feels like some cursed Pornhub script that found a budget.

The sisters are another mess. One is more playful and bratty, constantly teasing you, walking around half dressed, making “jokes” about you watching her change, then testing how far she can push before you snap. There’s a really funny scene where she pretends she doesn’t notice you in the hallway and starts masturbating in front of her open door, clearly wanting you to watch, and the camera just stays on her face way longer than necessary. I was sitting there thinking, why am I staring at her eyelashes during a nut scene, but somehow it worked. The other sister plays the colder type, acts all annoyed and distant, then later you catch her touching herself while whispering your name like she hates herself for it. The game keeps putting you in spots where you’re watching them from angles that feel really dirty, like peeking around the corner, or seeing reflections in mirrors. Sometimes it feels a bit too much, like the story is trying to shock you every five minutes with more corruption, more breeding talk, more “you’re mine now” lines. And at the same time I kept clicking because the animations are surprisingly smooth, nothing crazy flashy, just small details like how their hips move when you pin them down, or how the mom keeps eye contact when she’s riding you and talking about filling her up. There’s a whole scene on the living room couch where everyone kind of crosses that last line, and it’s both hot and weirdly awkward, like someone mixed a family reunion with a satanic orgy and forgot to invite shame. I thought I’d get tired of the linear story, but the way the corruption builds slowly, from teasing to outright obsession, actually pulled me along. Or maybe I’m just weak when big tits and demon horns show up in the same frame. Hard to say.

You know that moment when you’re staring at your screen, cock in hand, thinking “why the hell am I doing this again?” This game basically grabs that pathetic little thought, slaps you with a horny demon girl and goes, “yeah, you are addicted, shut up and enjoy it.” You play this poor bastard who jerks off so much he literally sends a horny prayer into the universe, and instead of a therapist, he gets a whole team of succubi answering the call. Not subtle at all. And it’s not just some random OC girls either, it’s like your private illegal multiverse porn folder came to life. One minute you got this smug redhead spy chick with the gymnast hips and attitude, next moment there’s that stretchy superhero mom whose ass honestly deserves its own loading screen, then you blink and boom, that blonde cosplay girl bouncing on your lap like she’s streaming for OnlyFans. It’s messy and stupid and hot. Mostly hot.

What I like is how the game doesn’t pretend you’re a hero. You’re basically a horny lab rat with “superpowers,” so every new girl you summon is part sex toy, part experiment. The “power training” scenes are just excuses for milking sessions, foot worship marathons, deepthroat practice, all wrapped in this half-serious, half-shitpost story about demons and paranormal deals. You get a new ability and your first thought isn’t “how to save the world,” it’s “how many ways can I make this ninja doctor with huge tits lose her mind on my cock.” The game lets you switch from being a controlling bastard, grabbing hair, forcing throats, filling every hole, to just lying back while some smug princess brat steps on your chest, spits on your tip and makes you say “thank you, mistress” before she even touches you. Sometimes it feels like Pornhub category roulette, but in a good way. Or a bad way. Depends on how you feel about drowning in cum.

There’s this one scene that stuck in my brain way too long. You summon this blue-eyed fire princess with that permanent “I’m better than you” face. She looks at your cock like it insulted her ancestors. You use a mind control ability on her, think “oh nice, she’ll become a soft, obedient girl.” Nah. She drops to her knees, smiles with that evil little smirk, and starts a blowjob that feels like she’s trying to ruin you on purpose. Teeth just barely grazing, hands twisting, drool everywhere, eyes rolled back, then she pulls off and wipes her face with her foot, making you lick her toes clean while she calls you her “pet.” I hated how much I loved that. Also the toes animation? Weirdly detailed. Like, someone spent real life hours on those arches and soles, and I can’t decide if I should applaud them or report them to someone. The only thing that annoyed me was this tiny sound effect in one menu that doesn’t match the click, and it’s driving me crazy every single time, and of course it will never get fixed. Anyway, you go from creampies to bukkake stacks to sloppy titfucks, with girls covered in your cum like it’s some cursed skincare routine, and the game just keeps handing you more universes to corrupt. It’s horny, shameless, a bit broken, and honestly feels like your late-night browser history turned into a demon contract you kinda don’t want to escape.
