Under One Roof: Step by Step is that kind of story that looks innocent for like five seconds, then suddenly you are sitting in front of the screen thinking, “Ok, I really should not be this hard from doing laundry and talking about rent.” It is quiet, slow slice of life, nothing explodes, nobody has magic powers, and still it gets under your skin. You’re this guy sharing a small house with three girls, each one wired completely different, and the game just keeps throwing you into these everyday scenes that slide from cute to horny in this really sneaky way. Breakfast chat about coffee? Five clicks later you are staring at her bare thighs because she forgot the shorts. Or she “forgot.” The whole thing is mostly conversations, tiny choices, and watching how your relationship with each girl shifts when you say something sweet, or when you absolutely fuck up and joke at the wrong time.

What surprised me is how normal some of the sex feels. Not porn-normal, like real-life awkward normal. First time I got a vaginal scene with one of the girls, it was not all “instant pornstar mode.” There was the nervous small talk, her checking if the door is locked, you trying to unhook her bra and failing like an idiot for two tries. The game actually lets that moment breathe. You see her legs shaking, not from some fake screaming, but from tension and excitement, and when he finally slides in, she doesn’t moan like a hentai character, she gasps, stops, adjusts. Then later, when you finish inside her, the creampie is not just a money shot. She lies there, breathing heavy, looking at you with that “you really did that” face, and the whole mood is this mix of warm, dangerous, and slightly stupid. I liked that a lot more than I should. There are softer romantic routes too, with real build up, hand holding, quiet cuddling on the couch, stupid jokes that actually made me laugh out loud once, then the same girl later is sitting on your lap grinding slowly while teasing you that you get turned on too easy. Very realistic, very unfair.

The relationship system is simple but not brain-dead. You choose who you spend time with, who you tease, who you comfort when shit goes sideways, and the game remembers. Say the wrong thing in a dramatic moment and she closes off, and you feel it later when she pulls her foot away when your MC touches it under the table. Speaking of feet, the fetish stuff is not subtle at all. One of my favorite scenes is not even full sex, just her sitting on the bed in oversized hoodie, bare legs, asking you to massage her feet because she is “so tired.” You start innocent, then she places your hand exactly where she wants it, and it turns into this slow, filthy footjob that still feels like a private joke between lovers, not just a kink checklist. She rolls her eyes, calls you a perv, but does not stop. The funny thing, the humor and drama sometimes crash together in weird timing, like a heavy emotional scene followed by a goofy underwear argument, and it feels slightly off, but in a way that reminds me of real life when people cope by joking at the wrong second. UI is fine, nothing fancy, I kept clicking the wrong choice once because the hitbox felt weird and got mad for a moment, then forgot about it when she climbed on top of me and started riding slow while whispering how she doesn’t want the others to hear. It is that kind of game. One minute you are arguing about dirty dishes, next minute there is cum dripping out of her while she kisses you like she actually loves you. I believed it more than I expected.

According to Sofia feels like reading someone’s horny diary while drunk, where every second page is a new excuse for why “this doesn’t count as cheating”. You’re basically hanging inside Sofia’s head while she lives with Bob, swears she loves him, and then spends the whole game bending the idea of loyalty like it’s a yoga class for her morals. She’s this bubbly blonde who acts dumb on purpose, but she’s not dumb, she’s just really good at pretending rules are optional if the dick is big enough or the dare sounds fun. One moment she’s cuddling Bob on the couch, promising she’d never hurt him, and the next she’s at some party letting a stranger draw on her boobs with a marker because “it’s just body art, like a tattoo, not sex”. The game leans into that constant mental gymnastics. You get those scenes where someone dares her to play strip poker, and she folds instantly, loses on purpose, laughs, and ends up naked on the table with guys staring at her, and she goes “Don’t worry, Bob, it’s only a game, not cheating if nobody cums… on the inside”. Yeah, the logic is that cursed.

What I liked is how the situations escalate without a big dramatic drum roll. It crawls up on you. First it’s just some flirty truth or dare, “show your panties” kind of thing. Then suddenly she’s on her knees in the bathroom during a house party, giving a messy blowjob to some dude she just met because technically “mouth stuff isn’t real sex” in her weird internal rulebook. And the game really milks the facial expressions. She has that innocent wide-eyed look while she’s swallowing, like she’s trying to convince herself and the player at the same time that this is fine, totally fine, nothing wrong here. There’s this one scene with a “backdoor only” arrangement that pretty much sums up the whole vibe. She’s drunk, straddling this guy’s lap, already half fucked, then stops and giggles, “But it can’t go in the front, that would be cheating, only the back is allowed.” And yeah, the game commits. You see everything, how her body reacts, how she tries to say no and then changes her mind mid-moan because “rules are flexible, right?” It’s filthy, sometimes stupid, sometimes actually funny in a fucked up way. She’ll finish with another guy, wipe her mouth, then go home to Bob acting like the sweetest girlfriend ever, baking something or snuggling him like she didn’t just get railed in a stairwell. I wish the game sometimes slowed down to show more of Bob’s side, his suspicions, but it kind of works that he’s this soft blur in the background while Sofia’s wild logic runs the show. It’s her world, he’s just the excuse she uses to call the whole mess “technically faithful.”

Jeremiah thinks his life finally starts to look less pathetic, he’s got this tall busty Freya hanging on his arm, ass that fills the whole phone screen, they fuck, they cuddle, he actually plans to be a semi-responsible adult for once. Then some cracked old wizard-looking geezer pops up, spits a curse, and suddenly your dick stats are in the negative. Not “haha funny shrink” but straight up humiliation level, like those porn ads you pretend you don’t see on Chrome. The whole game spins around that hit to his ego and this sick mission list the old man gives you. Ten missions. Fail or drag too long and there’s a “predator” orbiting around Freya, just waiting for you to fumble. You feel that pressure with every tap, like your cock is on a timer you can’t see, and the game keeps poking at your paranoia. You fix one mess, and instantly your brain starts going, “yeah but what if some hung dude is balls-deep in her right now while you swipe menus like an idiot?”

The dirty part isn’t just the sex itself, it’s how it plays with what’s going on in Jeremiah’s head. The corruption is slow, more teasing than splashy at first. Freya starts with this goofy loyal energy, sending you sexy pics, flashing those huge tits, joking about you “making up for size with effort” and all that. Then the situation tightens. She’s at the gym with some black trainer who looks like he was built in a lab, or at a club, or “going out with friends,” and your imagination scenes kick in. You’re there scrolling, clicking through choices, and it suddenly slams into these mental images of her riding something way bigger than what you’re packing now, moaning in ways she never did with you. Some are just her getting groped in a crowd, ass grabbed in the bus, hand “accidentally” on some dude’s bulge. Some are full-on interracial pounding with cum dripping down her thighs while Jeremiah sits on the side, jerking off and hating himself. The game tells you it’s “only in his mind,” but you know how that goes in NTR. Brain goes first, pussy follows.

What I actually liked is how the missions push you into nasty spots on purpose. You want to keep your points low to avoid the worst outcome, but to reach that you still need to let shit happen. It’s that classic “pick how badly you lose” loop you see in these games. Maybe you send her out in a tiny top to distract a guard and suddenly there’s a scene of her flashing her tits, laughing while some random guy takes snapshots. Maybe she needs money and you agree to “a little harmless flirting,” and it turns into a handjob in some backroom while she tells herself it’s only this once. Sometimes it cuts back to Jeremiah, tiny dick in hand, trying to masturbate to his own girl getting used like a slut, and you can choose if he hates it or leans into the kink. Doesn’t matter, the old bastard who cursed you is always there in the background, watching your progress like a troll dev reading comments on F95. The mobile format makes it worse, by the way. Sitting there with one hand on the phone, thumb tapping “Next,” other hand slipping down when Freya starts masturbating on cam for “somebody,” and you can’t even be sure that somebody is you anymore. It’s horny, it’s mean, it’s funny in that dark “haha I’m totally not into this, I swear” way, and half the time you’ll close the app and still keep thinking about whether her last “I love you” text was sent with another guy’s cum drying on her tits.

This thing starts like a drunk DnD session that got horny and never sobered up. You’re dropped into this little adventuring family circus: a Paladin you actually pick the sex for right away (male, female, futa, go wild), a Barbarian wife who has big “break the door and then ride you on the splinters” energy, and a Druid daughter who’s way too observant about everyone’s sex life. The game just pretends this situation is normal. No slow build. One moment you’re choosing attack options, next moment you’re basically debating if you should watch your own wife get pounded by someone else while you kind of like it and kind of hate yourself. I liked that. I hated that. I liked that I hated it. You get the idea.

The tone is weird in a good way. One scene has you arguing about tactics in a dungeon, and five lines later you’ve got a smug elf femboy shaking his ass in front of your wife like he’s farm-testing her loyalty. It’s not some clean “press button, get sex” thing either; you’re steering conversations that feel like they’re about honor, trust, party dynamics, then they slowly twist into “ok, who is going to fuck who and who is forced to watch.” The netorare bits hit hardest when you didn’t think you were choosing that, but then the Barbarian is moaning another name and you’re like “oh, right, that option.” I played on my phone in Chrome at first and had this moment where I alt-tabbed to Telegram mid-scene, came back, and the Druid was calmly describing exactly how wet one of the monster girls was while I’d forgotten where the hell the dialogue thread even started. By the way, the auto-forward sometimes feels too jumpy and I keep wanting to tweak it one tiny notch slower and always forget, which annoys me more than it should.

Then there’s the Undine futa, who basically steals the entire show. The story keeps pretending she has a “secret” like you can’t see this coming a mile away, but when everything finally comes out, the game really plays with it. You get routes where she focuses on the women in the group, and it isn’t just “haha, she has a dick, funny,” it’s more like “how deep can we go into turning the Paladin into a jealous mess while every female body in the party gets thoroughly re-plumbed.” I kinda wish there was a path where she went harder on the Paladin too, then again I don’t, because the whole fantasy hangs on that frustration and cheating vibe. Some of the funniest bits are actually right before the sex, like when characters try to talk all noble about temptations and duty while a succubus fire mage is casually describing in detail how she’s going to suck the soul out through someone’s cock. The humor hits at odd times, like after a really rough scene, someone drops a throwaway line that made me actually snort, then it jumps back into a blowjob choice menu without warning. If you want to wring every filthy drop out of it, don’t rush: manually save before big emotional choices, say yes when your gut screams no, and let the mess happen instead of trying to protect everyone. The most fucked up stuff hides behind the “this is a bad idea” options.
