There is something very funny to me about this game. You open it expecting the usual horny snack, some poolside tits, you click a little, jerk a little, close the tab, done. And instead it feels kind of like a rhythm game designed by a pervert who spent too much time in old arcades and then got way too obsessed with boobs and tentacles. It looks simple when you first see the pool, the girls in their bikinis doing that fake “I’m just relaxing here” pose, but your brain starts going into hunter mode the moment the monster slides into the water. The whole screen is a trap for your eyes. Tits bouncing, asses half out of tiny swimsuits, and under the surface you, this horny underwater thing that honestly feels more relatable than I wish to admit.

I play a lot of games with sound off, Spotify in the background, but this one kind of bullied me into turning the in‑game audio up. The little wet slaps when your tentacles snap out, that low, almost silly bass line that makes everything feel like a porn parody of an old coin‑op cabinet, and then those breathy moans when you actually catch a girl off guard. They’re not “high quality production” or something like this, they sound a bit compressed and dirty, like someone recorded them on a cheap mic at home while neighbors were away. And that fits too well. There is this moment when you line up a grab perfectly, the beat hits, your tentacle pops out of the water and wraps around some sun‑oiled thigh, and her bikini bottom gets pulled aside with this tiny little rip of fabric sound. It’s goofy. It’s hot. It’s kind of trash. I love it. I also absolutely hate how sometimes the same two moans repeat three times in a row, feels like my phone notification stuck on a loop, but after a while your brain files it under “sex noise wallpaper” and you move on.

What surprised me is how “arcade” it actually plays. You are not just clicking girls to see tits, you’re basically juggling timing and reflex like some horny version of whack‑a‑mole. They move around the pool, they sit on the edge, they swing their legs, and you’re threading tentacles between floaties and limbs, trying not to waste your shots. Miss, and you get that wet splash and nothing else. Hit, and suddenly she’s pulled halfway into the water, tits spilling out of her top, hair all over her face, and the music does this tiny shift that almost sounds like it’s laughing at her. Or at you. Hard to tell. Sometimes I wished there was a bit more variation, maybe different types of girls, different reactions, whatever, but then I realized the game kind of wants to stay in this one scenario, like a single porn loop stretched and remixed again and again until it becomes its own genre. Personally I also got irrationally annoyed at how one of the bikinis has this ugly pattern I can’t unsee, but I kept going anyway, chasing that feeling when three girls line up at the pool edge and you snatch them one after another with perfect timing, the soundtrack turning into this horny little drum solo while your monster becomes the most efficient sex predator in chlorinated water history.

Etna is already a little brat in the original games, so seeing her thrown here in this fucked up monster dungeon thing on mobile feels weirdly right. You open it and it just goes straight to her, chained up in the dark, red hair in your face, tits basically begging you to zoom in. No long story, no fake plot, just her and this huge demon thing looming over her. Touch controls are actually the main fetish here. You tap, drag, pinch, and she loses more clothes, more dignity, and somehow looks even hornier for it. At first I thought, ok, just another lazy hentai clicker, but then you start playing with the undress options and it feels more like you’re doing a custom photoshoot where the photographer is a sick fuck and the model is pretending she hates it but you know she doesn’t. Bra gone. Panties gone. Stockings half ripped. That tail of hers is moving like it has its own mind while the monster lines her up for another round. By the way, the UI button in the top left is ugly as hell and it annoyed me the whole time.

What really surprised me is how much they lean into the whole “bigger demon wins” thing. You’re not some self‑insert hero here. You are basically the camera of this bastard demon, stuck in POV, watching him slam this ridiculous monster cock inside her, both pussy and ass. Vaginal first, obviously, because they want you to see her open up slowly, wet, stretching around something that should not fit. Then, when you flick the little toggle and swap to anal, she tenses up, eyes wide, and that’s where I actually put down my phone once. Not because it was too much, but because I wanted to switch hand, my grip was getting sweaty. Funnily, the color slider for the demon’s skin is way more fun than it has any right to be. One moment he’s a classic black demon, next he’s some stupid bright purple thing ramming her from behind, like a rejected Monster Hunter boss that decided to quit and become a porn star instead. Totally immersion breaking, and I still kept doing it.

The animations focus heavy on the hips and the way her body reacts. She bounces forward when he thrusts, her butt cheeks jiggle when he pulls out, there’s that shiny line of spit or cum or whatever leaking down when he switches holes. You move the camera just a bit, suddenly you’re right up in her ass, watching that ring stretch and swallow every vein on that thing. Then you move up and see her face, half crying, half in heat, drool on her lip, hair messy, collar tight on her neck, and yeah, at that point it felt more intense than half the “***” tagged stuff on FapNinja or whatever garbage I usually scroll on Chrome. I thought the sound would be trash but the wet slaps and her little choked moans actually got me. Plus, it loads quick in browser on my phone, way better than some laggy Unity stuff. Still, one thing drove me insane: you can change demon color but not his eye glow. Why. Why give me that much control over his skin and then leave his eyes stuck like that. Every time I looked, it pulled me out of it a bit, then the monster went back into her ass and, well, I forgot to care again.
