Man, this One Punch Man parody hits different than I expected. You're playing as some wannabe hero trying to climb the rankings while dealing with Tatsumaki and other monster girls who are way more interested in fucking than fighting. The whole thing starts innocent enough - you're doing typical RPG stuff, training stats, picking dialogue options - but then suddenly you're getting handjobs from green-haired psychics and the game's asking if you want to use toys during combat encounters.

The turn-based system is weird because sometimes you're actually fighting monsters and sometimes you're just trying not to cum too fast during sex scenes. Like there's this one part where I'm battling some creature and the next screen I'm balls deep in her getting a creampie scene. The transitions don't make much sense but honestly who cares when Tatsumaki's giving you that look. Though I gotta say the humor lands pretty well - they nail that OPM vibe where everything's simultaneously serious and completely ridiculous. The protagonist's this skinny virgin type who keeps getting into situations way over his head, which tracks for the source material.

What threw me off was how the transformation stuff works - characters change during scenes but it's not always clear why or when it'll happen. One minute you're talking to a normal-looking girl, next she's got tentacles or whatever and you're doing anal. The masturbation mechanics feel tacked on too, like they needed to hit certain tags but didn't know how to integrate them naturally. Still, when it works it really works - the oral scenes with monster girls are genuinely hot and the whole "hero ranking" thing gives you actual goals beyond just seeing titties. Plus the parody elements mean you're not taking any of it too seriously, which helps when the plot gets completely bonkers.

Mike Oxmaul is the kind of guy you look at and think, “yeah, that dude’s gonna have a normal college life.” Then you play ten minutes and realize, nah, this poor bastard is cursed by the porn gods. He’s short, he’s under-equipped, everyone around him seems bigger, hotter, more confident, and the game just loves to rub it in. Half the time you’re laughing, half the time you’re clenching because the humiliation hits a bit too close.

The setting is standard university stuff at first: dorms, classrooms, clubs, parties, a bit of sandbox wandering where you click around the campus and see who’s available. What makes it hook you is how every little choice you make about Mike’s ego spirals into something filthy. Say the wrong thing to the smug futa roommate and suddenly she’s got him on his knees, making him “prove” he deserves to stay in the room. Pick the cocky option with the tall redhead milf professor and you get this scene where she slowly unbuttons her blouse in her office, sits on the desk, and then laughs when she sees what he’s packing. She still lets him bury his face in her tits, then calls him her “tiny little toy” while he tries not to cum in his pants. It’s mean, but it’s hot, and the game just keeps doing that mix of arousal and bullying.

The sex is all over the place in a good way, and the 3dcg animation actually manages to sell the dirty stuff. There’s a scene in the locker room where Mike is hiding in a shower stall, watching two thick girls share a shower and start playing with each other, and you can either stay quiet and jerk it or “accidentally” knock a shampoo bottle. If you fuck up, they catch him, push him against the tiles, and one of them starts stroking his cock with her feet while the other films it on her phone, laughing at his size, threatening to leak it unless he does exactly what they say. Later there’s a club sequence where a drunk married woman grinds on him on the dance floor, her wedding ring right in your face, and if you go along with it you get pulled into the bathroom for messy cheating sex, her bent over the sink, whispering how her husband could never make her gush like “this little loser.”

The game swings hard between humiliation and actual romance in a way that feels weirdly real. One moment Mike is used as a cum rag in a group scene, taking turns giving sloppy oral and getting painted by bukkake while a crowd laughs at his ahegao face, and then a few events later you’re on a quiet date with a shy classmate who admits she’s still a virgin and kind of into smaller guys. You can actually choose to be gentle, focus on kissing and slow vaginal sex, her clinging to him and whispering his name while he tries not to blow too fast. Or you can lean into corruption, turn her into a needy mess who ends up begging to be creampied in a public place, risking pregnancy because “no one notices us anyway.” That mix of sweet and fucked up gives the story more bite than I expected.

There’s a lot of kink variety buried around the campus and nearby streets. Street corners with girls clearly doing prostitution on the side, where Mike can either pay to be dominated by a tall trans escort who makes him lick her heels and then rams his ass with a toy, or stumble into a cheap quickie behind a bar with a big ass milf who demands a titfuck first, squeezing her lactating nipples all over his face. One of the most ridiculous moments for me was a “study group” that turns into a gangbang when a popular girl decides she’s bored, strips naked, and invites everyone to use her while Mike awkwardly watches. You can have him join in and get lost somewhere between thighs and ass, mostly ignored while the bigger guys pound her, and then she still pulls him in at the end, jerking his pathetic cock until he shoots on her face for the final messy finish.

Pacing is a little weird sometimes. You’ll have this intense anal domination scene where Mike gets pegged by a smug futa who keeps calling him her “practice girlfriend,” sticks a vibrator in his ass and makes him walk around campus, then next thing is a goofy humor bit in a classroom about a stupid group project, like nothing happened. The jokes land more often than not though, especially the self-aware ones. There’s one event where Mike is watching porn on his phone, and the video is basically a parody of the kind of inflated hentai bullshit the game itself is flirting with: huge tits, impossible ahegao, milk everywhere, furry ears, the works. Then his real-life neighbor, this curvy girl with glasses, walks in on him, sees what he’s watching, and quietly asks if he wants to try “something smaller, but real.” That switch from meme-level ridiculous to intimate POV oral, with her slowly licking his shaft and teasing the tip while staring up, made me actually shut up and pay attention.

I also kinda hate how sometimes the teasing never pays off. There’s a footjob scene in a lecture hall where a girl slips off her shoes under the desk, starts grinding his crotch with her toes, and the camera angles are great, you feel every twitch, but then the professor calls Mike to answer a question and it just cuts without a finish. No climax, no punishment, nothing, and the game just moves on like it never happened. It bothered me for way too long, I kept checking the walkthrough and everything, and yeah, it still annoys me. At least the voyeur stuff makes up for it. Creeping around dorm corridors, catching quick looks through half open doors, seeing titfucks, anal, some interracial rough sex where Mike can only watch and jerk, hoping nobody notices him, that stuff is done dirty and right. And when a tall, dominant girl finally drags him out of his hiding spot and makes him strip in the hallway as payback, forcing him to stand there naked while she strokes him by hand and makes him cum in front of a small crowd, you realize the game really understands how to mix shame, lust, and a bit of twisted romance into one messy university fever dream.

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.

There’s something weirdly hypnotic about the way this whole thing opens - like the scene just melts you into their space, no preamble, no “hey, press start for smut,” just that slow tension simmering before anything actually happens. The animation rolls smoother than I expected; nothing clunky. It has that feel of a private fantasy someone animated out of pure obsession instead of for clicks. You can almost hear Ben’s breath hitch before he even touches her. It’s not really about plot (I mean come on, who’s pretending it is?), but there’s this messed-up sweetness in how it starts quiet. The sound design keeps pulling you back: tiny sighs, sheets brushing skin, the rhythm faint at first and then snapping hard once hands stop pretending to be innocent. Somewhere between awkward cousin tension and full-on porn logic, the thing just… lets go.

The best part, surprisingly, is the pacing - it doesn’t rush. When Gwen shifts under his touch, her body language says everything before any actual thrusting begins. And yeah, once it gets explicit - cowgirl with those slow hips, doggystyle with his fingers gripping too tight, that sloppy blowjob that looks *too* practiced - it’s impossible not to notice how much effort went into animating every drool line. There’s texture everywhere, like somebody cared too much about skin catching the light. I still think the facial scene goes a bit overboard (there’s a point where it looks more like performance art than sex), but maybe that’s the charm? Also, sidebar: whoever picked the moan layer nailed it, that muffled little catch right before the creampie hits - pure serotonin.

Story-wise, it barely exists, yet it feels weirdly believable because the silence between them carries guilt and hunger at the same time. No silly popups telling you what position next, just eyes, movement, friction, that loop where they keep testing boundaries without admitting it. I swore I’d stop watching after one run, but there’s something magnetic about how shameless it gets by the end, like watching a dream that doesn’t know how to filter itself anymore.
