Office Rivals starts with something stupidly simple: overtime, dead office air, screens burning your eyes, you hating your life but still trying to win that imaginary productivity war. Then Nanako walks in, all sharp tongue and big boobs pressed into that tight shirt, and suddenly Excel is the last thing on your mind. It feels like that coworker you swear you hate, but you remember how she used to laugh with you in college, how you used to check out her chest and then pretend you were noble. Here it hits way harder, because the game does not pretend this is just cute romance. It lets you be horny, petty, jealous and soft at the same time. One moment you are arguing about who closed the deal, next moment her hand is in your pants under the desk, stroking you slow while the monitor light hits her face. It is intimate and kind of mean at the same time, and I love that.

The whole thing is from your POV, so when she leans in, you see her tits fill the screen, buttons straining, just waiting. There is this one scene in a meeting room where she pretends to be all business, glasses on, talking about quarterly numbers, and under the table she guides your hand under her blouse. Fingers push her bra up, you feel the weight of her tits, and when you pinch, she gasps and tries to turn it into a cough. Then the game just goes all in. She is on her knees between your legs, licking the tip, drool sliding down your shaft. They actually animate the teasing, the tongue circling, her eyes looking up like she is saying "yeah, I win, you lose", while she jerks you with both hands. When you finally shove it between her boobs and start fucking those big soft tits, the physics are not perfect, but somehow that makes it hotter. They even give you internal view when you finally bury yourself inside her, watching the head push deep into her, stretching her open, like you are invading this rival you are not supposed to care about anymore. You do. A lot.

What really messed me up is how the game ties all this filth to your choices. You can play it like an idiot who just wants to pump her full of cum and brag in his head, or like some lovesick fool who pretends the creampie is just "stress relief" while clearly wanting to knock her up. There are multiple endings, so that first time you lose control and finish inside, you are not sure if it is just a hot office accident or the start of a pregnancy route. There is this one path where she holds your dick at her entrance, smirking, saying she forgot her pills, and you can either pull out and watch the cum spray on her belly, or push in and keep thrusting until she wraps her legs around you and milks you dry. Later you see her nipples swollen, a bit of lactation starting when you suck hard, and it is such a small detail but it stays in your mind. The voyeur angle shows up too, like when a coworker almost walks in and you are balls deep in her, her hand slapped on the glass to keep from moaning. I was literally alt-tabbing between this and my work Slack, thinking "if Nanako was real, she would absolutely ruin my life, then make me thank her while she rides me again in that stupid office chair." And I would let her, obviously.

A horny love story that starts all sweet and soft and then slowly turns into “ok, how filthy can we get without breaking this couple.” You play a young guy stupidly in love with his girl Ana, absolutely obsessed with her huge tits and ass, but even more obsessed with people looking at her. At first it is just little stuff. Tight clothes when you go out. A skirt that rides up when she sits. That moment in the bar when you pretend you did not notice the guy on the next table staring at her cleavage, even though you are watching his eyes like a hawk and getting hard from it. The game really likes that feeling of your stomach twisting because you are proud and jealous and horny all at the same time. It is not some instant gangbang fantasy. It is slow burns, teasing, him catching a reflection of her bending over, her licking a spoon a bit too suggestive while she pretends she is not doing it on purpose. And you are stuck in his head, hearing all the fucked up things he wishes would happen and all the scared thoughts right after.

Everything is told from his point of view, and that is the real kink here. You are not seeing “just” sex, you are seeing his brain melting while he pushes her toward more risky stuff. He wants to show her off, he wants people to notice that round ass under a transparent dress, he wants them to know she gives sloppy deepthroat in private, but at the same time he is terrified that one day she might like the attention too much. There is a lot of voyeur-style tension. Windows not fully closed. A camera maybe placed just a bit higher than it should be. Public teasing where she pretends to be shy while her nipples are clearly trying to break out of the top. Some scenes go all in with ahegao faces, spit and drool when she is blowing him, that messy mix of romance and porn where you can believe these two actually care about each other even when he is holding her head down on his cock and using her like a toy. Sex is not just boring missionary. You get oral, anal, riding scenes where her tits are bouncing all over the place, and a nice focus on how she reacts when she knows someone might be watching. Sometimes the humor cuts in at weird moments, like he will crack a stupid joke during a pretty intense corruption beat, and it works and doesn’t work at the same time, which somehow fits the whole amateur “guy discovering his own perversions” vibe.

What I liked is that your choices feel like you are poking the fantasy, not rewriting reality. You are not branching ten different endings. Instead you nudge things: push her to wear something sluttier for a “harmless” party, agree to a risky dare, choose a more dominant answer when she timidly asks what you want from her, and then later you might get a short extra bit where a coworker stares at her cleavage too long or a friend makes an offhand comment about how she looks like the type who would cheat. There is some playing around the border of swinging and netorase and jealousy without jumping straight into hardcore cheating in the main route, and that constant “what if he actually lets her go further” sits in the background. The art relies on AI style 2D CG so sometimes you get these weird almost-perfect shots of her body that feel slightly off if you stare too long, but honestly when her mouth is wrapped around his cock and her eyes are rolled up with that full ahegao expression, I was not really complaining. Except maybe about that one tiny detail with her phone case color changing between scenes. Still annoys me and I cannot even explain why. Anyway, if you enjoy being stuck firmly in the guy’s POV, loving his girl to death while also wanting to parade her around half naked for the world and see how far she will go, this thing leans hard into that messy, horny, insecure fantasy and just keeps poking at it until you squirm.

Everything goes to hell before you even click “start”. Dad bailed to some beach with his side chick, robbed half the city, left the house in debt and full of memories that smell like cheap perfume and broken promises. You drag your sorry ass back from college, thinking you’ll maybe crash a few days, fix some paperwork, then vanish again. Instead you walk into a home full of women who remember you very well, some a little too well, and suddenly that “temporary stay” turns into the hottest, messiest, most illegal summer of your entire life. The place is about to be turned into a college dorm, money is tight, secrets are tighter, clothes are optional, and apparently everybody thinks you’re the one who has to “take responsibility”.

What hit me first wasn’t even the sex. It was that weird feeling of coming back to a house where you used to jerk off in silence trying not to wake anyone, and now you’re standing there face to face with that thick, soft, totally out-of-your-league woman you grew up around, and she talks to you like you’re not a kid anymore. The first time she leans over the kitchen table and you get that POV shot of her tits nearly falling out while she asks you something completely normal, it’s like your brain splits in two. One half is thinking “this is wrong”, the other half is screaming “please bend her over the counter right now”. The game leans hard into that tension. Sleepy late-night visits where someone “accidentally” crawls into your bed. A shower scene where you swear the door was locked and then it just… isn’t. A hand brushing your crotch in the hallway, a “joke” grope that lasts way too long, someone sitting in your lap during movie night a little too close, her ass grinding slowly while pretending nothing is happening. It starts as teasing and harassment and then it slowly turns into mutual corruption. You’re not just some horny puppet either. You choose. Who you comfort, who you push away, who you let keep touching you when you should stop them. The story remembers that later. She remembers that. Her sister remembers that too, which gets real interesting when the twins start getting curious at the same time and your pants are already down because of something completely different.

The sex itself goes from sweet to filthy so naturally it almost feels like real life if real life had way more big tits, lactating milfs and zero HR department. One scene you’re just cuddling and talking about how everything went to shit after you left, kissing her slow, taking her virginity soft and careful while she squeezes your hand and tries not to wake anyone in the next room. Next scene you’ve got her riding you reverse on the couch, her big ass bouncing in your face while she milks your cock with her pussy and begs you to fill her up. The POV shots during creampies are stupidly good, especially when you get to see it drip out while she tries to hold it in because she “doesn’t want to get pregnant” and then later there is a whole route where that risk is not just “risk” anymore. If you like oral, there’s a moment where you’re supposed to be studying and she’s under the desk, stroking you, licking the tip, whispering shit in your ear while your messages ping on your phone. There are messy titfucks with cum on her face, footjobs where you don’t even know how the hell you got into that position but suddenly you’re throbbing between painted toes, interracial threesomes where two totally different bodies fight over your dick, and a group scene that feels like the end result of every bad decision you made along the way. Some girls you gently corrupt, others drag you down with them, and sometimes you wake up with someone riding you half-asleep, using you like a toy and pretending tomorrow will still be normal. The voices sell it hard, too. The gasps when you slip it in her ass the first time, the little laughs when she makes you cum from just her hand, the shaky breathing right before she lets you inside without a condom because “just this once”. There are multiple endings depending on who you commit to or if you try to hoard a whole harem like a greedy bastard, and yeah, you can screw up and lose people. That weird ache in your chest when you pick one girl and see another walk away quietly… somehow hits almost as hard as the orgasm you got from her earlier while she was sitting on your face and grinding.

Mark drags his ass back to his hometown thinking he’s just crashing at the old house for a while, and the whole thing instantly turns into a slow-motion sex disaster. Dad is gone, ran off to the Caribbean with his side piece after quietly robbing his company blind for years, and left behind a wrecked family home, a broke ex-girlfriend, and a pile of debts that might as well scream “you’re screwed” in neon. The “solution”? Turn the house into a college-style dorm and stuff it with girls who already know Mark way too well. Childhood friends, twins who used to tease him when he was still a virgin, a neighbor milf with that tight yoga-ass that makes you pause the game just to stare, and a couple of ex-crushes who suddenly don’t seem so out of reach now that everything is falling apart. The mood jumps all over the place: one moment you’re joking about the house turning into a horny hostel, the next you’re in a quiet POV scene where an old flame is jerking you off on the couch, voice quivering, whispering how she missed “this” while you were away, and yeah, she means exactly what you think.

What hits first isn’t some big dramatic twist but the way the girls remember things you forgot. Like that one scene with the chocolate cake in the kitchen where one of the twins licks cream from her finger way too slow and says “you used to watch me do this when we were kids, you perv” while her tits basically rest on the counter. You get options that look harmless, then five clicks later she’s on her knees giving sloppy oral, moaning in your language headset-style, and you realize you dug your own horny grave. The humor keeps undercutting the filth too: you can be elbow-deep in a lactation scene with a milf who “just needs some relief” and in the middle of a titfuck she cracks a joke about charging rent for every creampie you leave in the house. It should kill the mood, but it somehow makes it hotter, because it feels like real people messing around, not plastic porn robots. Some routes lean pure romance, like falling asleep after anal with a girl who cuddles you, talking about future babies and maybe pregnancy, while other paths let you drift into group sex chaos where three girls fight over whose turn it is to ride you, one sitting on your face, another grinding on your dick, someone else just quietly masturbating in the corner because she “likes to watch.” There are endings you can feel coming and others that sneak up, like screwing the wrong person behind someone’s back, that little netori twist where you pretend it’s just a handjob in the shower and suddenly you’ve ruined a relationship you were actually starting to care about. Best way to enjoy all of it? Be a little reckless. Say yes when the twins ask you to help them “study,” don’t skip the teasing scenes, let people get jealous, let mistakes pile up, and save often so you can go back and see what happens if you let the shy girl be the one who finally climbs on top and fucks you until she’s shaking.
