It’s weird how a game can make you forget what you were actually doing before you clicked it, right? I opened Isekai Brothel thinking it’d be another lazy copy of those generic dating things where everyone stares blankly while you mash through dialogue, but this one… it plays dirtier. Not just in the obvious way (though yeah, there’s plenty of skin and moaning and all that), but in how it messes with your head. You start bouncing between universes like some horny multiverse courier, and suddenly you’re arguing with a half-demon waitress about who’s topping tonight. Then the game throws a slime girl at you, and she calls you “master” like she means it, and I swear I almost dropped my mouse.

The writing is all over the place - half of it’s like someone’s fanfic got drunk and made out with another fanfic, and I kinda love it for that. One scene you’re flirting with a cold swordswoman who barely talks, next thing you’re being pinned by a dragon maid who insists she’s just “checking your health.” Some of the transitions are a mess; one minute it’s sweet, then bam, full-on rough roleplay with no warning. I tried to complain about the pacing, but then a certain pink-haired girl whispered something about “rewarding loyal patrons,” and honestly, whatever I was mad about just evaporated. The voice bits - when they’re there - sound like someone recorded them in a closet, but that weirdly fits the vibe. Like, you’re not supposed to take it too seriously.

There’s a little bug where the bed scene music overlaps with the dialogue if you skip too fast. It drove me nuts, but also, I didn’t stop clicking. Something about collecting girls from different worlds, each with their own twisted little quirks, scratches an itch I didn’t know I had. Half of them act like they hate you, the other half worship you like a god, and both make sense somehow. It’s not classy, not polished, not even pretending to be - but when the screen shakes and she says your name like that, who even cares.

You know that feeling when you’re scrolling on your phone, bored out of your mind, and you start thinking “yeah, I kinda wanna flirt with half the anime multiverse right now”? This game leans right into that. It’s a mobile-style dating sim where your whole job is to talk, tease, and slowly push your way from cute banter to full-on filthy with a bunch of familiar faces. One minute you’re trying to keep your shit together while Tsunade leans in with those ridiculous tits, the next you’re trading playful jabs with Marin Kitagawa like she’s your chaotic cosplay girlfriend who absolutely knows she’s out of your league. It’s very much a “pick a waifu, poke at her until she cracks, then enjoy the view” setup. You answer questions, pick dialog options, earn points when you say the thing she wants to hear, and each correct move nudges the relationship from “hi, senpai” to “okay, pull your dick out already.”

What I like is how the game doesn’t pretend it’s some deep, tragic romance. It pretends for like 10 seconds, then goes straight into horny nerd brain. You start with small talk, a bit of teasing, then she starts hinting, and once you’ve stacked enough points, the clothes start vanishing. One date you’re laughing with Aqua while she’s being useless and bratty, the next date she’s grinding in your lap and calling you a pervert like it’s your fault. Rias acts all composed, polite, almost royal, but you keep pushing the right answers and suddenly you’re getting your cock squeezed between those huge tits she pretends are a burden. There are titfucks, messy handjobs, slow teasing oral where she holds eye contact like she wants to watch you lose control, the usual “oops I sat on it” vaginal sex, and yeah, anal too if you unlock the right scenes. Some girls treat it as a reward, some as a challenge, some as “shut up and enjoy it.” I had this moment with a certain dragon milf where she’s bouncing on top of me with that massive ass, smiling like she’s finally found a new toy, and I genuinely forgot to click the next line because I was too busy staring.

It’s not all straight either, which is nice. You’ve got traps like Astolfo and Felix in the mix, cute and flirty and way too confident, and if you’re into that, the game doesn’t tiptoe around it. They flirt hard, they suck you off like they’ve practiced, they ride you like they’re trying to prove something. Some routes feel more romantic, like a soft slow-burn with a girl like Rem, where you actually care a bit about the conversation before you end up buried inside her, and some are pure chaos, like Darkness begging you to use her like a toy while you’re thinking “ok, I’m the degenerate here but wow.” It’s kinda funny how sometimes the writing hits this surprisingly sweet mood, then two screens later you’re balls-deep and watching a loop of her moaning and drooling, legs shaking. There’s a harem vibe too once you realize just how many characters are waiting for you. Best way to enjoy it? Don’t rush. Take a character, answer her correctly, watch her shift from “oh, we’re just talking” to “fuck me harder” and let yourself get sucked into each scene. Screenshot the faces you like, replay the ones that make you twitch, and let the game do what it clearly wants to do: melt your brain in the dirtiest, laziest way possible.

It’s messy in a way that feels almost too personal, like reading someone’s horny dream journal that accidentally got turned into a game. The first time I saw Rias just leaning in, her hair catching that fake moonlight, I thought the animation was glitching - too smooth, almost alive. Then she smirked, and I forgot about the weird clipping on her shoulder. The story pretends to care about demons and contracts, but it’s really just an excuse to throw you into this feverish loop of moaning, glowing eyes, and clothes that evaporate faster than logic. The main guy acts like he’s confused about what’s happening, but his hands sure know where to go. You start judging him for being a pushover, then realize you’re clicking through every scene like a hungry idiot.

I kept thinking about how the sound design feels like someone recorded it in a bathroom but somehow it works - it’s raw, kind of embarrassing, and that’s what makes it hot. Akeno’s laugh cuts through the music in this way that makes you feel like she’s laughing at you, not him. There’s this one scene with Koneko that’s so awkwardly animated it loops twice before syncing up, and it made me laugh right before it made me need to close the curtains. The mind control bit is weirdly casual, like everyone just shrugs and goes along with it. I don’t even know if that’s sexy or lazy. Probably both.

The pacing is nonsense - one moment you’re watching a serious “contract ritual,” next thing you’re watching him buried between thighs that look like they were rendered by someone who’s never seen knees before. But it doesn’t matter. It’s that kind of game that doesn’t want to be perfect, just filthy enough to keep your brain fogged. I opened it thinking I’d hate it for being another cheap fantasy knockoff, but now I can’t even remember what I was supposed to be mad about. Maybe that’s the point. Maybe it’s just the moans.

You die on a shitty first date and wake up staring at Rias’ tits. That’s basically the tone right away. No long build up, no “oh no what happened to me”, just you flat on your back, her in that tight outfit, looking down like she bought you on discount and is not sure if the product is broken or just horny. And guess what, you now belong to her and her little devil harem, which is honestly the most honest contract I’ve seen in a while.

The fun part is how the game treats the High School DxD cast. Rias is pure power fantasy and also total brat. One scene she sits on your lap, pushes your face in her boobs, calls you her “pet project”, and later acts like she did you a big favor by letting you cum on her stomach instead of just her hand. Akeno shows up like a walking BDSM quiz: “Question one, how much electricity can your balls take?” and then giggles like it’s afternoon tea. The teasing is constant. They drag you through the school halls in that classic uniform vibe, Asia bumping into you, apologizing with her big soft chest pressed in your face while Rias watches with this lazy smile, like she’s checking if you’ll stay loyal or just melt. Then you blink and suddenly Miki is pinning you to the couch, hips grinding, acting like “oh, I’m just helping Rias break you in.” There is a scene with toys that actually surprised me: Akeno pushing a vibrator along your shaft while Rias is sitting a bit away, legs crossed, pretending she’s only here to supervise, but her panties are getting wet and you can see the 3D jiggle when she moves wrong for half a second. On the other side you have Raynare and the others popping in with that monster girl edge, wings, claws, that cruel smile. Kalawarna treats you like office property: titfuck as a “performance review”, stroking your cock with those heavy boobs, asking “Are you loyal to your mistress?” while you’re trying not to blow early, because the game actually lets you fail that scene if you mess the timing. Which is funny and annoying at same time.

Some of the humor hits really hard. Like Asia walking in on Akeno tying you up, then trying to “help” by joining, but she only knows sweet missionary, so the whole thing turns into this bizarre combo of soft, loving vaginal sex from one side and cruel female domination from the other. The animated bits are honestly the best thing here. Rias bouncing slowly while riding you, red hair falling over your chest, then suddenly she leans forward and whispers something stupid like “You’re only alive because I wanted a toy” and you’re like, okay, step on me more. The camera sometimes lingers too long on feet for no reason, which is weird but also kind of on brand for DxD degeneracy. There is one scene with Mittelt where she pretends to be all innocent and then uses a toy on you with this little smug grin, and the only thing I hated is that it ended right when it got really nasty. Also, small complaint: they make you run around the school for dialogue triggers a bit too much when honestly I just want Rias to choke me with her thighs again. The adventure parts are there, clicking around, choosing who to serve first, but my brain kept going back to Akeno’s “quiz” and that one time Tsubasa just silently grinds on you in the clubroom like it’s no big deal. It’s messy, horny, sometimes stupid in a good way, and somehow the fact you died on a date fades away under a pile of big asses, bigger tits, and very smug devils who know exactly how much control they have over your dick.
