The whole thing feels like someone found a Flash file from 2006 on a dusty hard drive and just... put it online. The brunette has these massive, ridiculous tits that keep swelling bigger and bigger, which is exactly what the tag says, but the animation is so janky it loops in this hypnotic, almost broken way. You're basically just clicking a giant veiny cock between her boobs, trying to match some invisible rhythm. Speed click, then slow down, then speed up again, the game never tells you what it wants. I failed like twelve times before anything happened.

And when it does unlock the next scene, the titfuck gets more intense, her expression barely changes but her chest inflates to stupid proportions. The sound design, if you can call it that, is just these wet slapping noises that cut off abruptly. There's this one moment where the cock glitches through her sternum and I couldn't stop laughing, but also it was weirdly hot? The whole thing is unpolished garbage but I kept clicking. The breast expansion happens in stages and you don't notice until suddenly her areolas are the size of dinner plates and the physics give up completely. Hard sex is a strong word for what's here, it's more like a very focused, repetitive loop of boobalicious obsession.

My wrist started hurting from the speed clicking. The rhythm mechanic is never explained, you just fail until you figure out the pattern by accident. I still don't know if I actually beat the final animation or if the game just broke. The big cock clips through everything, the big boobs bounce with no weight, and I think there were supposed to be more positions but I only ever got titfuck. Honestly the jank is part of the appeal. It's not trying to be polished, it's trying to deliver one very specific thing and it does that while falling apart at the seams. The brunette's dead-eyed stare during the whole thing is either terrible or perfect, I can't decide.

Hotel harem setting always sounds kinda cheap in my head, like porn from old torrent days, but here it actually feels cozy and weird at same time. You show up, get this half-broken hotel from grandpa, and pretty fast it turns into your personal corruption playground. It starts slow, like a dating sim where you grind money, talk to girls, learn their habits, but the longer you stay, the more the place feels like a cage where everybody slowly forgets where the line used to be. One moment you just check the maid’s stats and buy her a cute outfit, and few in-game days later you’re attaching nipple clothespins while she thanks you for “training” her better. The jump from wholesome to holy shit is honestly the main charm for me. It doesn’t slam you with nonstop porn; it lets you work for it, tease it out of the characters, which makes the first time an innocent girl starts masturbating on camera just to help pay her rent hit a lot harder. For a game about boobs, it’s weirdly good at pacing tension.

The girls themselves are a whole mess in a good way. You’ve got the elf maid who arrives already broken in spirit, treated like a slave for centuries, and the game leans into that dynamic hard. At first you’re just trying not to be as awful as the world around her, then you catch yourself enjoying how obedient she’s become, and suddenly that “maid sim” loop of chores, rewards and punishments feels a bit too arousing. There’s the ultra-religious virgin walking around with a body that screams “fuck me” while her brain screams “you’re going to hell”, and watching her go from blushing when you grope her a little, to shaking and squirting all over the sheets while begging you to creampie her, is such a slow-burn corruption that I actually felt kinda proud of myself. In a fucked up way. Same with the yandere tendencies on one of the girls: at first it’s cute jealousy, then she’s basically edging herself for you, waiting for permission to cum, and you realise the game quietly slid into orgasm denial and hardcore devotion territory without big fanfare. That’s what I liked the most, I think. It doesn’t pop a huge banner saying “now you unlocked BDSM”. You just try one spanking scene, then another, then you’re fastening her collar before breakfast like it’s nothing. Of course, some routes drag too long, and the grind for money or affection kills the mood when you just want to pin someone to the bed and rail her ass. Also the mobile feel of the UI gets a bit annoying on desktop, especially when you’re trying to quickly jump between girls for late-night spying and end up tapping the wrong room like a dumbass. Still, when you’re standing in a corridor, peeking at a girl fingering herself in the shower, hearing little lines about how she “only thinks of you now”, and knowing you’re the one who turned a shy tenant into your personal toy, the whole messy, horny hotel starts to feel like home in the worst possible way.

Massive Hearts feels like somebody took a normal porn game idea, dropped it in a blender with a size queen fetish, then forgot to hit “smoothie”. The result is messy, wet, kinda ridiculous and somehow really hot when it clicks. You start as this regular dude, or futa if you want, and from the first scene you notice the camera really loves tits. Not just big boobs. The kind of breasts that look like they’re arguing with gravity and winning. The sound design surprised me first actually: the little breathy gasps, the heavy jiggle noises when a giant girl leans over the screen, that subtle sticky sound when she squeezes milk from herself during a titfuck. Sometimes the moans clip or repeat awkward, but when you’ve got a milf twice your height riding your cock until her tits literally swell bigger from arousal, it works. There’s this moment early where you’re pressed against a giantess’ chest, she pins you to a wall with pure boob, and the audio shifts to this muffled heartbeat and her slow breathing while she grinds you between her breasts and whispers like you’re tiny prey. That felt intimate and porn-y in a weird soft way, like ASMR for degenerates.

The pacing jumps all over the place. One scene it’s slow teasing, a girl shyly masturbating while watching another lesbian pair lick milk off each other’s nipples, almost romantic, and then suddenly you’re buried inside this hyper-sized futa with a cock longer than your torso, and she’s milking herself all over you while begging for a creampie. The game doesn’t care about “realistic”. You’re fucking girls way larger than you, and somehow your dick still matters. Some of the 3D models look great when the light hits curves just right, especially the creamy skin and the sheen on wet areola when they start lactating heavily, but then a hand clips through a thigh or an ass looks like it’s made from two different girls pasted together and my immersion just jumps out the window. Still, when that giant milf bends over and her giant ass fills basically your whole field of view, with little squishy sounds as she lowers onto you, it’s hard to stay mad. There’s this harem vibe that builds up quietly: you realize after a while that several of these towering women all want a piece of you. One is playful and uses her tits like a bed, letting you fuck her cleavage while she lazily strokes herself, milk leaking over your stomach; another is more dominant, picking you up one-handed and ramming you into her dripping pussy like you’re a living sex toy, then holding you in there while she clamps down and floods you with juices. I kept noticing small things like how the breathing changes right after you cum inside, or how the camera lingers on the cum drooling back out after a creampie, and then ignoring bigger things like actual emotional build-up. But ok, I didn’t come here for a Shakespeare milf. What threw me a bit was how fast the transformations happen: one girl goes from “big tits” to “are you sure this is still human” in basically one scene, breasts inflating, ass swelling, body stretching taller while you’re still inside her, and you feel like a plug trying to hold back an ocean. It’s absurd and also kinda thrilling, like hentai logic made interactive, even when the animations stutter or the faces sometimes look like they’re halfway through blinking during orgasm. Still, when the giantess leans in close after you fill her, tits swollen, milk dripping, and whispers that you’re hers now, and you know there are three more colossal women waiting their turn offscreen, it sticks in your head longer than it should.

You start as this small-town girl who suddenly lands in a big city for university, and the game just quietly goes, “yeah, you’re thirsty for knowledge, but also… you’re gonna feed some really bad habits.” It plays like a cute anime dating sim at first, all soft colors and shy smiles, but it’s absolutely not shy about what it actually wants to do with bodies. Every girl you meet has her own hang-ups, and almost all of them can be pushed toward getting softer, heavier, more stuffed, more… overflowing. It’s like someone took a wholesome campus slice-of-life and then asked, “ok but what if everyone slowly turned into walking curves because they can’t say no to dessert or late-night snacks or one more drink with whipped cream?” and nobody said no.

What I liked is how the weight gain and all the expanding parts aren’t just “you clicked, her boobs get bigger, congrats.” It kind of sneaks up. You’re on some normal date at a café, she orders something modest, you tease a bit, suggest the giant milkshake, then a second one, then some cake “since we’re already here,” and the dialogue starts getting this hungry tone. She blushes, complains she’s full, but her eyes light up when you suggest bringing takeout too. You come back for another event and suddenly the sprite has thicker thighs, her ass is straining her skirt, she’s tugging at her top because her tits don’t sit right anymore, and the text is like, “I don’t know why my clothes feel tight, it’s probably the laundry.” Sure. Then you hit the scenes where you deliberately stuff her until she groans and presses her hands into a round belly, and the game just leans into it. Not joking around. Belly bulges, shirts riding up, bras digging in, the whole thing. Sometimes it goes pretty far, girl pinned in her chair by her own ass, panting, still licking cream from her lips, asking if there’s more. The stuffing focus is strong, and it actually feels erotic instead of goofy, which is dangerous if that’s your thing. Breasts swelling out of a top mid-conversation, buttons popping, jiggling every time the text box advances, that kind of “oh shit this is escalating fast” feeling.

What bugged me a bit: the pacing is weird in spots. You get these long streaks where you’re clicking through campus small talk, class stuff, background drama, and you think “ok maybe this is just a normal VN with some chubby fanservice,” and then suddenly a single choice turns the scene into full-on gluttony porn with her moaning around a spoon and talking with her mouth full. No real ramp. I kinda love that and hate it. Also one character’s pants look like they’re painted on when she starts getting really thick around the hips, but then the next CG, the proportions hit just right and you forget you were annoyed. The writing has that slightly awkward, non-native vibe sometimes, like someone typed “I feel my body more heavy now” and forgot to fix it, which low-key makes it hotter because it feels less polished and more like a fetish passion project. There are a few routes where the expansion focuses more on hips and ass, and you watch her go from cute in jeans to basically one big ass with a girl attached, knocking stuff over in her dorm with her butt and pretending it’s an accident. Meanwhile you are absolutely pushing her there with “oh come on, have another plate, you worked so hard today” while your character’s inner monologue is like, “I want to see that zipper surrender.” It does that thing where the MC acts supportive and sweet but the choices are all like: encourage, really encourage, or absolutely ruin her self-control. And the game smiles at you and hands you another scene where she waddles a bit heavier, breathing harder, but saying she’s never felt so “free.”

I play this one on my lunch break at the office, switching between the game and Excel like a fucking ninja, and it actually feels kinda perfect for that. You start in this small bar, nothing fancy, nothing trying too hard, and there’s this girl at the counter who looks like the kind of cute you swear you saw on Reddit once at 3… ok, at night, never mind. She’s got that “I’m tired, something’s wrong, but I’m still hot” vibe. At first she’s just normal sized, normal body, normal everything, and the game doesn’t rush it. You talk, you flirt a bit, pick a line here, a stupid joke there, and it almost feels like a very scuffed dating app conversation, just with way more tits later. The fun part is how her body slowly starts changing while you keep coming back during the “weeks”. It sneaks up on you. One visit she’s a bit bustier, you’re like huh, ok, then next time you’re staring at your monitor thinking “there’s no way her shirt button is surviving this scene”. Then later her ass just says fuck physics and the dev acts like this is just casual. The good thing is they actually write her as a person, not just a pair of balloons with a face. She’s worried, a bit confused about what’s happening, cracks some jokes, gets flustered when you go a bit rough with the teasing. There’s a lot of horny humor, that “I’m not a slut... unless you ask right” type. Sometimes it hits, sometimes it’s cringe, which somehow makes it feel more real, like some guy trying too hard in a Discord server.

The build up to the lewd stuff is the best part and also kinda annoying. You’re clicking through these chats and bar scenes, watching her tits go from “nice” to “Jesus Christ, how do you sleep on those” and her ass keep inflating like someone forgot to turn off the pump. When the sex finally hits, it leans into that rough energy, grabbing, pressing her against things, her body bouncing everywhere like the dev is just screaming “more jiggle, more jiggle” in their head. Cumshots are messy in a good way, not shy at all. You get that moment where you’ve been teasing her for a while, then you finally pin her and just go all in, and she reacts like her whole oversized body was made to be used like that. It’s not subtle. You finish on her face, on those giant tits, on that swollen ass, and the game lingers just long enough for you to sit there pretending you’re “reading emails” while staring at a screen full of dripping curves. The funniest part is how barebones everything around that is. Interface feels like someone knocked it together while watching porn on the second monitor. Few choices, you kinda expect a deep system, but nah, it just gives you enough to feel like you’re poking her personality while her body goes crazy in the background. One time I misclicked a line while my boss walked past and she reacted all shy and horny at once, and I had to alt tab to Slack with this massive sweat going. Anyway, if you’re the kind of degenerate who likes watching a girl slowly turn into a walking titty-booty combo while you pretend to “get to know her”, just take it slow, don’t skip through the early chatter, and let each new curve surprise you like it’s your first fucked up bar crush.

I keep coming back to Gwen's route like picking at a scab, honestly. The whole thing starts with this girl who wants to get bigger, and I mean that in every possible way, and the game just... lets you decide if she's got a dick or not. That toggle at the beginning feels almost too casual for what comes after.

The weight gain stuff hits different when you're watching her muscles swell at the same time. There's this one scene where she's trying on old clothes and the seams just give up, and her biceps are literally stretching the fabric while her chest is doing that thing where buttons become projectiles. The AI art actually captures that weird in between state where she's both muscular and soft, which shouldn't work but somehow does. I spent way too long on that one transformation sequence where she's flexing in the mirror and her lats just keep spreading wider. The futanari content is there if you want it, and it's not shy about showing everything when things get explicit, which they do, frequently.

The visual novel structure is pretty bare though. You click, you read, you watch Gwen expand. Sometimes you meet characters from other universes and I genuinely don't know if they're references I'm supposed to get or just random cameos. The dialogue can feel like someone fed a bunch of fetish forum posts into a generator and didn't bother cleaning up the output. But then Gwen will say something weirdly earnest about wanting to be her biggest self and I'm like, okay, maybe there's something here about body modification as identity exploration. Probably not though.

What bugs me is how the growth feels uneven. Her boobs will suddenly double in size between scenes with no explanation, but the muscle development takes forever. I wanted more of those gym sequences where she's actually struggling with weights, you know? The breast expansion just happens, but the muscular growth feels earned somehow. Also the AI art sometimes gives her extra fingers during the more explicit scenes and it takes me right out of the moment. Nothing kills the mood like counting digits when you're supposed to be focused on other anatomy.

I gotta say, the whole "check their hands and teeth" mechanic got me good the first time. You're Sarah, holed up in this shitty apartment while the RAG virus turns people into these massive, mindless things that keep knocking. And you have to decide who to let in. The first visitor seemed normal enough, some guy looking for shelter, but then I noticed his fingers were swelling right there in front of me and I slammed the door so fast. My heart was actually pounding. That's the thing about this visual novel, it tricks you into thinking you're playing a standard survival thing but then Sarah starts changing too and suddenly you're not sure if you're trying to save her or just watching the inevitable.

The weight gain progression is wild. Sarah's body just balloons scene by scene, her tits getting heavier, her ass spreading wider, and the game doesn't shy away from showing every detail. There's this one visitor, I think his name was Marcus or something, who keeps coming back and the way he talks about her transformation, like it's the hottest thing he's ever seen, it gets under your skin. The psychological horror part isn't just about jump scares, it's about how tempting it becomes to just give in and let the virus take over. One ending had her so massive she couldn't even move anymore and honestly I just sat there staring at the screen.

The eight visitors all have different kinks and secrets, and some of the dialogue is genuinely unsettling mixed with being incredibly explicit. I wish the game tracked which visitors you've encountered across playthroughs though, because I kept forgetting who I'd already seen and it got confusing. The BBW expansion stuff is front and center, no subtlety, and if you're into that specific niche of horror where the monster is also weirdly seductive, this hits different. Just don't expect polish, the whole thing feels rough around the edges but maybe that's the point.

Game feels like finding some forgotten Flash porn game on a sketchy site, just cleaner and with way more obsession over boobs growing pixel by pixel. You’re basically sitting behind this girl’s eyes while her whole life turns sideways because of one weird little shop that looks like it spawned out of a cheap JRPG. She’s a regular student, stressed about exams, roommate drama, boring campus stuff, and underneath it all she’s horny and insecure in a way that’s way too real. At first she’s just curious about changing herself a bit, like “what if my tits were a size bigger, no big deal”. Then you start mixing these shady potions and suddenly her bra is fighting for its life and her ass is spilling over the chair while she’s still pretending everything is normal. The story really leans into that slow “oh shit, I can’t button this shirt anymore” spiral. Most of the heat is in those quiet moments when she’s alone in her room, squeezing herself in front of the mirror, sliding her fingers under fabric that obviously does not fit anymore, pretending she’s just checking progress when she’s actually getting soaked and flustered about what she’s turning into.

What I liked is how horny the writing is without shouting at you every line. When she walks back from the shop and feels her panties riding higher because her ass quietly grew on the way, it’s written like she’s confused and turned on at the same time. She’s trying to sit like normal in the classroom while her bra digs into her ribs, her nipples hard as hell under a thin top, and everybody else is just talking about homework. Those classroom scenes are more erotic than some actual sex CGs I’ve seen in other titles. The game lets you screw around with potions and pacing, so you can go greedy and push her into big, heavy curves stupid fast or just slowly stack “little changes” until she suddenly realizes her whole center of gravity is different. One time I messed up a mix and her ass jumped a size mid cutscene and she almost knocked over a chair backing up, then pretended she meant to do that. That tiny stumble sold it harder than any magic sparkle effect. The sex itself is more about her being overwhelmed by her own body. She’s touching, grinding, trying to find a position where her new curves don’t get in the way, failing, then giving up and using that as fuel. When she lies on her back and her tits slide to the sides and she freaks out because they weren’t big enough to do that before, that’s the kind of detail that sticks in your head when you close the tab. I wish the sound had just a bit more weight to it, like heavier breathing or some fabric straining noises, but the silence almost helps, like you’re right there in her room, hearing only clicking and her thoughts getting more and more filthy.

The cutscene where Voluptas first appears is a mess. I mean that in a good way? Her boobs clip through her own divine robes, the Honey Select 2 lighting makes her look like she's standing under a flickering fluorescent tube in a basement, and her voice lines are pure cheese. But there's something about that unpolished, almost amateurish framing that makes the whole thing work. It feels like a fever dream, not a product. The animation studio in me screams about keyframe smoothing, but the degenerate in me just clicks through to the size control power. The power is literally a slider. You meet a girl, the dialogue is what you'd expect from a translated isekai fantasy, and then you get a UI element that lets you inflate her chest like a balloon. The first time you use it on the elf girl, the mesh stretches with this weird, unnatural deformation that's honestly more fascinating than any perfectly sculpted 3DCG model. It's janky, and that jank is the whole personality.

The sandbox loop is basically nonexistent. You wander, you talk, you fuck. The masturbation scenes are oddly detailed, the camera lingering on the protagonist's hand like it's the most important character model in the game. And then, during a spanking scene with the catgirl, the sound effect just... stops. No fade, no resolution. It's a bug, obviously. But it's the kind of bug that makes you laugh and then immediately forget as the next creampie scene loads with a breast expansion animation that looks like someone's first Blender tutorial. The harem building is just a checklist, but the oral sex animations have this one specific, sloppy tongue motion that feels weirdly authentic compared to the robotic vaginal sex loops.

The whole isekai setup is just an excuse, and the game knows it. The goddess gave you the power of size control, and you use it. That's it. The romance tag is a lie, it's just a series of escalating, messy, physics defying encounters. I wish there was a DLC that added some actual tension, maybe a rival with a shrinking power, or a scene where the expansion goes wrong and you have to deal with the consequences. Something to break the monotony of the slider. The jank is charming until it isn't, and then it's just a broken sound effect during a hand job and you're staring at a static image wondering why you're still clicking.
