The Mastrumoto 4000 achievement list is basically a checklist of holes. I'm tracking unlocks like some degenerate accountant. Anal entry, double stuff, oral finish, the usual. But the game doesn't give you a clean path. You fumble through a basement POV, clicking on a brunette who's already bent over some eBay fuck-machine that looks like a repurposed engine block. The 3D models have that unpolished CG sheen, like someone learned Blender last Tuesday and immediately decided to make porn. It's perfect for this. A polished look would ruin the grimy basement vibe.

The rough sex tag isn't lying. There's no gentle lead-up. One moment you're positioning a sextoy attachment, the next the machine is jackhammering and Megan's mascara is a lost cause. The cumshot mechanics are weirdly specific. You can trigger them early, which I did by accident, and the scene just... continues? Like the machine doesn't care about your timing. It's a machine. That's probably the point. I wish the double penetration sequence had more feedback. You just sort of assume it's happening based on the angle. But then she makes this choked sound and you know. You just know.

I spent ten minutes trying to unlock a specific oral scene that I'm still not sure exists. The series tag suggests there's more of this somewhere, other subway fucker chapters maybe. This one feels like a middle child. The basement setting gets stale fast. Same concrete walls, same harsh lighting. But that's also why it works. It's not trying to be anything else. Just a room, a machine, and a brunette with no survival instincts. The POV never breaks. You're James, you're a creep with a magical sex robot, and you're going to watch it do all the work. Achievement popped for double penetration. Still missing the one for... something. Back to the basement.

The whole thing feels like a fever dream after you scroll past a "Selena Gomez basement" meme at 2 AM and your brain just runs with it. You got Justin Bieber, right, and he's tied up in some latex getup that probably cost more than my rent. The girls, they look like famous people but not quite, like someone squinted at a magazine and tried to draw from memory. One of them has that Selena face but the eyes are off, another could be Barbara Palvin if she had a bad day. Whatever, you're not here for the lore.

The bondage mechanics are simple. Click, drag, repeat. You strap him to a chair, then a table, then some weird metal frame. The latex textures are actually decent, shiny in a way that makes you want to touch the screen but also maybe wash your hands after. There's a moment where you apply a ball gag and the sound effect is just... wrong. Like a wet fart. I laughed, then felt bad, then kept playing.

But here's the thing. The BDSM stuff is there, sure, but it's all so mechanical. No build up, no tension. You just click through positions like you're filing taxes. And the Justin model has this dead-eyed stare the whole time, like he's already thinking about his next album flop. I spent way too long trying to get the wrist cuffs to align properly and they just clip through his arms. Minor detail, but it bugs me.

The dungeon setting is dark, which hides most of the jank. You can almost pretend it's intentional. Almost.

Don't expect a story. Don't expect logic. Just expect a weird little time waster with latex and questionable celebrity lookalikes. The whole thing crashes if you try to use the whip too fast, by the way. Not that I'd know.

BDSM Dungeon Monitor 2, right. The first one already had that whole vibe of a grimy little browser game you'd find on some forgotten corner of newgrounds back in the day, and this follow up is the same, deliberately scuffed around the edges. The basement setting is just a few grey walls and shadows, the brunette model looks like she was ripped from an early 2000s render, and the animations... they have this weird jitter to them, like the whole thing is held together with digital tape. And honestly? That's the point. It's not trying to be some slick, hyper-realistic simulator. It's raw.

You start with her just standing there, and you've got this tray of toys. The touch controls are super basic, just click and drag, but there's something about the way the whip leaves red marks or how the anal dildo just pops into place with zero ceremony. It's functional filth. Then you get to the strip phase, and the bondage gear is pretty standard, some rope here, a harness there, nothing a seasoned deviant hasn't seen. But then the game kind of forgets its own pacing. You spend ages fiddling with the nipple clamps, and I mean ages, getting the placement just so, and then the hardcore fucking segment is over in a flash. A flash of that same jittery loop, I mean. Cumming inside is an option, outside is an option, all the holes are on the menu, but the transition between "playing with toys" and "absolute railing" feels like a skip button was hit by accident.

Feels like there's a missing middle step. A DLC that added some proper reaction system would be huge. Not just a canned moan loop. I'm talking about her flinching when you go back to a sensitive spot with the whip, or struggling against the bondage ties in a way that actually impedes your clicking. Make me work for it, you know? The whole thing is this weird mix of totally unpolished and weirdly specific, like someone's private fantasy coded in an afternoon. It's the kind of thing you click through once, get what you need from it, and then close the tab. Doesn't overstay its welcome, but doesn't exactly redefine the concept of browser-based BDSM either. Just... is what it is. A dirty little sketch of a game.

Her eyes roll back different when you use the black dildo. Not the little one you start with, that's just warmup. The big one. The one that makes the chains rattle against the basement floor. You know the sound I mean. That specific clink when her legs jerk and the metal bites into her ankles. I spent way too long just... clicking. Watching the animation loop. Forgetting the tongue and fingers were even options.

The whole setup is so barebones it's almost funny. Like someone made this in a weekend with assets from a 2005 flash site and said yeah, that's done. The basement is just gray walls. The chains are just there. The girl has that generic hentai face where she's supposed to look innocent but you know exactly what's coming. And somehow that jank makes it better? I dunno. There's no pretense. No attempt to be anything other than what it is. You click. She reacts. The orgasm meter fills. You switch toys. Repeat. My brain went completely smooth. Achievement hunting mode activated but instead of collectibles it's just... making the anime girl cum with increasingly ridiculous objects.

The dildo size jump is absurd by the way. Like comically large. The kind of thing where you laugh and then keep using it because the reaction is the most extreme. The anal option unlocks and you think oh of course there's anal. Of course. And the sound design, if you can call it that, is just wet noises and her gasping. Looped. Relentless. I had it on while scrolling twitter and forgot to mute and now my neighbor probably thinks I'm watching something deeply cursed. Which I am. But like, deliberately unpolished cursed. The kind where you respect the honesty. No crafting system. No dialogue trees. Just basement. Chains. Dildos. Orgasm.

You know what, the clicking thing is actually kinda clever. Not the whole reflex bar thing, that's whatever. But the way the chain rattles when you miss the timing. There's this little audio cue, this clink sound, that somehow makes the whole thing feel more... present? I dunno. Spent way too long just messing up on purpose to hear it. The game is literally just a loop with a busty hentai girl chained up in a basement, and you click to fill a meter. That's the whole deal. But that chain sound, man. It's got this weight to it. My actual mouse is this cheap plastic thing from Logitech, feels like a toy, but in the game the chain sounds heavy. Real iron. It's a weird disconnect that I kept thinking about.

The girl's design is fine. Big cock, huge tits, the standard hentai proportions where her back must be made of steel. The art is deliberately sketchy, like someone drew it in a rush but knew exactly which bits to detail. The shine on the lips is a nice touch. The animation when you hit the sweet spot is janky though. It snaps from pose to pose. Like a flipbook missing pages. I actually laughed the first time. Not a sexy laugh. But then I kept playing anyway, which I guess is something.

There's no story. You're just some dude, she's just some bitch in chains. It's honest, I'll give it that. No pretense. My one real complaint, and I can't let this go, is the cursor. It's a default system cursor. A tiny white arrow over this dark, moody basement scene. Completely breaks the vibe. Couldn't they have changed it to a hand or something? A little pointing finger. It's such a small thing but it bugged me the whole time. Anyway the pleasure bar fills up, she gets louder, you finish. Then it loops. That's it. Back to the clinking chain.

Baka’s got this whole setup in his basement now. Like, proper torture frame, restraints, the works. The kind of thing that makes you wonder what he was doing before Mizuki left town. She’s his usual... test subject I guess? But she’s gone and this thing is just sitting there, all cold metal and potential. The game doesn’t waste time with some grand story. You’re just there, in this dim room, and there’s this girl. Big tits, obviously. The kind of exaggerated proportions that make the whole thing feel like a fever dream.

The controls are janky as hell. Clicking around, trying to figure out which restraint goes where, and half the time the camera swings into some weird angle where you’re staring at a wall texture that looks like it was made in 2004. But that’s almost the point? It’s not trying to be slick. The humor lands somewhere between cringe and actually funny, mostly because Baka’s internal monologue is so damn earnest about his little torture chamber project. He’s so proud of it. There’s this one moment where you attach the wrist cuffs and the physics just give up, tits clipping through everything, and instead of being annoyed I was laughing. The BDSM stuff is pretty straightforward. Restraints, some light torture implements, nothing that’s going to make you question your life choices but enough to feel like the game knows its audience. The basement setting gets repetitive fast though. Same grey walls, same shitty lighting. Would it kill them to add a window or something?

What really saves it is the modding scene. Some absolute degenerate out there already swapped the girl model with something even more ridiculous, and there’s a patch floating around that adds more... let’s call them interaction options. The kind of thing that makes you wonder who has the time. But that’s the beauty of these janky little games. They’re more like a canvas than a finished product. The base game is whatever, but the community takes it places the original dev probably never imagined. Or maybe they did. Baka seems like the type who’d approve.
