This one feels like some horny quiz night inside Kuoh Academy that got out of hand and nobody hit the pause button. You start as the usual pervy dude in a school uniform, brain full of dirty trivia about Rias, Akeno, Koneko, Rossweisse and the rest, and the whole thing plays like you’re hosting your own x‑rated game show in your head. “Question one, class: how long can you keep eye contact with Rias while she’s slowly jerking you under the desk?” Wrong answer? You still win. The story is just an excuse to hop from one girl to the next, like switching tabs on Pornhub. School corridors, club room, empty classroom, that one suspicious storage room where nobody ever stores anything, just cum. Every scene feels like some fan on Reddit said “what if this happened in High School DxD” and the dev just replied “ok” and drew it.

Animations are simple but they hit the dirty spots. Rias dropping to her knees, that lazy smile like she already knows your search history. Akeno playing the “oh, I’m so innocent” act for half a second and then going full sadistic priestess, sucking you off slow, then fast, then using her hand like she’s speedrunning a category on Twitch. Koneko’s scenes are shorter, more deadpan, like she’s annoyed you’re enjoying it this much but still stroking you anyway, her face barely changing while your character is losing his mind. The blowjob loops are the kind where you can just sit there, one hand on mouse, the other doing exactly what you think, and the rhythm doesn’t feel weird. It even has those tiny details, like lips glistening and spit strings when she pulls off the tip, which is such a small thing but suddenly you’re like “ok, someone knew what they were doing.” And then you notice Rias’s fingers clipping through your thigh in one animation and it annoys you way more than it should, and you keep staring at it instead of her tits, and now it’s stuck in your brain forever.

What’s funny is how unpolished the whole flow is, but in a good way, like a horny fanfic that never got edited. Dialogue jumps straight to the point: one second you’re “studying” in a normal school setting, next second you’re getting a handjob by a window like it’s totally part of the lesson plan. There’s no slow romance build, it’s more like: “Rias walks in. You get hard. She notices. Oral scene.” That’s it, that’s the script. Some lines sound like they were written by someone who studied English using nothing but Pornhub comments and Discord DMs, which honestly fits the vibe. The parody angle is obvious but also kinda off; sometimes Akeno talks more like Rias, Rossweisse randomly shows up with a vibe closer to a flustered substitute teacher from some other anime, and nobody cares, because at that moment she’s kneeling between your legs and stroking your shaft while pretending she’s just “helping a student relax.” I liked how the masturbation scenes are treated like mini intermissions, like “commercial break, jerk yourself with the girl on screen,” then back to more story that you’re half reading, half skipping, just hunting that next animated loop. In the end it feels less like a polished game and more like you accidentally clicked the filthiest High School DxD playlist on some shady streaming site and decided, yeah, I’m staying here.

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.

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.
