This kinetic novel hits different when you're into that slow-burn psychological territory. The premise isn't groundbreaking - husband confesses his cuckold fantasies to wife, things escalate - but damn if it doesn't nail the emotional buildup. Your protagonist wrestles with these taboo desires while his relationship transforms into something neither of them expected. The corruption element creeps in gradually, which I appreciate way more than those games that jump straight to the hardcore stuff without any character development.

The AI-generated artwork serves its purpose, though some scenes feel a bit stiff during intimate moments. But honestly? The narrative carries this thing hard. Watching the wife's gradual transformation from hesitant participant to someone who genuinely enjoys the attention... that's where the real heat lives. The swinging scenarios build naturally from their initial conversations, and the netorase dynamic actually feels authentic instead of forced. There's this one scene where she's trying on lingerie for another guy and the internal monologue just perfectly captures that mix of excitement and guilt. The corruption isn't just physical either - it's psychological, which makes everything feel more intense when things finally get explicit.

What bugs me is how the confession scenes sometimes drag on longer than necessary, especially early on when you're just waiting for something to actually happen. The pacing improves once they start exploring their boundaries, but those first few chapters test your patience. The cheating elements come into play later and honestly caught me off guard - wasn't expecting the story to venture into that territory given how consensual everything starts. The creampie scenes are well-executed when they finally arrive, and the big tits/big ass focus isn't overdone like some games where that's literally the only selling point. For a kinetic novel, it manages to keep you engaged even when you can't make choices, which says something about the writing quality.

Rush description during subway, sorry if my english go weird.

This one throws you right into that quiet, uncomfortable space at home after a funeral, but then slowly turns it into something way more fucked up and horny than it has any right to be. You’re Saigo, the older brother, stuck in a tiny apartment with Hana who used to be lively, now she’s like a doll that talks. Her face is empty, eyes kinda dead, but she still says pervy stuff with flat voice and it messes with your head. Game doesn’t even pretend to be normal romance for long. It starts with “care,” then it becomes “how far can I push my sister while telling myself it’s therapy.”

There’s no choices, it just moves, one scene into another, and you just sit there on your phone like an idiot on the bus watching your own character cross line after line. It starts with harmless touching, “checking her temperature” while she lies on the bed in her school uniform, shirt just a bit open, bra visible. You tell yourself it’s nothing, but then your hand stays too long on her chest and the text says her nipple is hard under the fabric. She doesn’t react, no blush, no cute anime squeal. Just “Is this necessary, onii-chan?” in that blank expression, and it’s somehow nastier than normal moaning. Later she’s in her classroom, sitting by the window, and you get a flashback of when you first noticed her tits got huge in middle school. That scene lingers way too long on how her blouse buttons are fighting for their life. Four screens of text only about the way the fabric hugs her big ass when she leans forward. I actually missed my stop once because of that stupid button tension.

The sex escalates like a slow boil. There’s this one scene in the bathroom where she’s brushing her teeth and you come in behind her, and the camera just stays on the foam around her lips while she stares at her reflection. You touch her hips, and she doesn’t move away, and somehow that’s hotter than if she jumped on you. When you finally get her to wrap those soft hands around your dick, she keeps this weird monotone commentary like “The hardness is increasing” while pumping you, no emotion, drool shining on her chin. The first blowjob is wild because she goes from robotic to full ahegao in about three lines, tongue out, eyes rolled, tears at the corners, like her brain just flipped a switch. You cum on her face and she calmly asks if this is part of the “treatment plan.” That line killed me and turned me on at same time. And the creampie scenes later, on her bed with the old photo of your dead mom on the nightstand looking right at you, are just wrong in the exactly right way. She wraps her legs around you, huge boobs bouncing, pussy soaking, and only then you notice at the very bottom of the screen there’s a tiny text note about her still wearing her school socks. I don’t know why that detail hit harder than the whole harem side thing with the other girls at school, including that scene where you eat her out behind the gym while your so-called “girlfriend” is waiting on LINE. The cheating angle barely gets called out, which somehow makes it filthier. It’s like the game assumes you already accepted you’re trash, so it doesn’t bother to judge you. Or maybe it does and I just pretended not to see it.

You wake up with that heavy, horny fog in your brain, and instead of your boring room you’re in this chapel that looks like somebody let Pornhub redesign a cathedral. Stained glass, candles, crosses, and front row you got a nun with tits that do not care about gravity at all, trying to decide if she wants to save your soul or ride it. She talks sweet and holy while her outfit is cut so low it might as well be a polite suggestion. And the game just looks at you like: “Alright, sinner, what kind of mess you wanna be?”

The fun part is how it keeps throwing those “innocent” options at you and they never stay innocent. You tell the nun “I want guidance” and she hears “please press those huge soft miracles into my face and whisper prayers while grinding on my lap.” You pick the serious, holy line, and five clicks later she’s on her knees calling you something between “my child” and “my master” with a tongue that clearly skipped bible class. Then you wander out of the chapel and the whole place opens up into this demon playground. Succubus lurking around every corner, hips moving like they’ve got their own physics engine, tails sliding around your legs, horns, claws, that pretty red skin that screams “terrible idea” in the best way. You say one wrong thing to a demon girl and suddenly she’s pinning you to some stone altar, sitting on your cock like she’s collecting your soul one thrust at a time.

What I liked is how the choices actually feel like they change the flavor of the smut, not just the wallpaper. Go respectful with the succubus and she goes slow and teasing, dragging those big breasts over your chest, kissing you soft while still milking you like she’s on a timer. Act like a cocky bastard and she flips you, rides you hard, claws in your back, calls you “toy” while smiling like she owns your life now. Same with the nun: lean into her faith and she turns the whole thing into a corrupt mass, whispering holy lines while stroking you with trembling hands, like she hates how good it feels. Push her buttons and she snaps, climbs into your lap, skirt around her waist, moaning into your ear that she belongs to her god and also to your dick. The visuals love big curves, thick asses bouncing on altars, soft stomachs folding a little when they bend over, jiggling everywhere when the scene gets rough, and the camera never tries to be artsy, it just shoves your face exactly where you were already thinking. It’s messy, horny, sometimes goofy as hell, and every path is basically one long “what if I said yes to the worst idea” fantasy where the answer is always: a nun, a demon, or both, sitting down on you like you’re part of the furniture.

Sometimes you just want trash science and thick mistakes, you know? This game is exactly that: one awkward nerd in a lab, a bunch of sketchy chemicals, and zero adult supervision. It starts all innocent, like some goofy parody of those anime where the genius kid wants to become the next big brain of the world. He’s mixing his “super serum” in this tiny lab, all proud, like he’s breaking new ground. Except the only thing he actually breaks is the size limit on asses and tits. The first time his formula “fails” and you see what it actually does, I laughed out loud and also had to tab out for a second because, yeah, it hits.

The vibe is weirdly cozy and horny at the same time. You’re basically clicking through this visual story where every bad decision he makes leads to someone getting way, way bigger than they were five minutes ago. And not like small upgrade. I’m talking “how is her spine still functioning” kind of growth, bouncing off the screen, clothes surrendering instantly. There’s a really nice rhythm to it: bit of dialogue, some nerdy babbling about cells and enhancement, then boom, another girl drinks the “healthy supplement” and suddenly her ass is doing its own gravity experiment. The CG scenes are the real star here. They don’t pretend to be subtle, it’s just full-on worship of size, curves, and that moment where the character realizes “oh shit, I’m actually getting huge.” One scene where the girl leans on a table and her new tits almost knock over half the equipment had me cackling like an idiot.

What I liked is that the game leans into the fetish instead of apologizing for it. Like, if you’re here, you already know what you want: expansion, growth, bigger, bigger, bigger. And it delivers that in a way that feels playful, not clinical. The nerd boi is such a dork, he talks about his formula like it’s going to win a Nobel Prize, while the player is obviously just waiting to see who gets inflated next. At the same time, some of the dialogue is kinda clunky and tries to be too clever, which slows down the fun when you just want to watch another “oops, wrong dosage” moment. There’s one random line about safety regulations that pissed me off for no reason, like bro, you’re literally turning people into walking sex balloons, nobody cares about your lab coat. Still, when the serum finally kicks in and her hips start outgrowing the chair, music barely matters, writing barely matters, it’s just pure “holy shit, look at that” energy. Honestly the only DLC this needs is more ridiculous aftermath scenes, like trying to fit through doors or sit on a chair that obviously never had a chance. But yeah, he keeps pouring that thicc juice and we keep watching, pretending it’s about “science” while our mouse hand is busy with totally different research.
