Luminary Protocol looks at you like a normal isekai porn VN, then slowly grabs you by the throat and reminds you it is actually a horror story where your cock is just another weak point. You wake up in this twisted copy of Earth, some weird mashup of school corridors, ruined city blocks and floating fantasy shit that should not be in the same sky. Gods and demons run the whole thing like a sick game show. You’re the typical male protagonist on paper, virgin, awkward, POV everywhere, but the game really likes to push you into ugly choices while your dick is still out. One second you’re flirting with a thick milf teacher in a half-collapsed school wing, watching her tits bounce in these smooth little animated loops while she’s grinding on your lap, and the next second the hallway behind her is crawling with something that used to be a girl and now has insect legs and too many teeth. It never fully lets you feel safe, even when your pants are off and her bra is on the floor and she’s guiding your hand up under her blouse for that slow groping scene that goes on just a bit too long. I played it like a coward, always picking the non-aggressive, “let’s talk about this” stuff, skipping any fight chance. No combat, just sneaking through scenes, hiding in classrooms, and somehow I still ended up knee deep in monster girls who wanted to ride me more than kill me. Or both, hard to say.

The sex itself swings around between kinda sweet and straight up fucked. There’s this school rooftop moment with your “totally not related” older woman from home, and the game leans hard on that taboo shit. She’s scolding you about dangerous magic while her blouse is open and she’s pressing your face into her tits because “you need comfort.” The camera goes low, she pulls your cock out, spits on it and does this lazy handjob with her soft annoyed voice in your ear, like she’s mad at you for getting hard but still jerking you off anyway. Later she pins you in a storage room, panties around one ankle, and you get full vaginal sex with her trying to keep quiet while the other students scream somewhere down the hall from whatever monster just spawned during a Convergence. The AI CG is bizarre in a good way, bodies look a bit too perfect and then you notice some tiny wrong detail in the background that makes your skin crawl. Sometimes the boobs are huge, stupid big, and the titfuck scenes turn into this soft, slow suffocation where the girl talks about “maybe letting you cum inside next time” because pregnancy here is not just a fetish, it has plot weight. One route actually hints that fucking the wrong girl bare could spawn some magic hybrid kid that the gods want, but I refused any raw creampie like I was playing a pacifist path of my own balls. I tell myself I am here for the story, the multiple endings, the weird alignment stuff, but I reloaded a save three times just to watch one oral scene again where the shy monster girl with horns and big tits practices kissing your shaft like it’s some dating sim homework. She melts a bit when you don’t push her, and the game quietly remembers that for later scenes. Or maybe I imagined that. Hard to tell when you’re half hard, half scared, and watching your choices drag you toward something that feels like both romance and a slow, wet apocalypse.

The story kicks off with a guy who is way too in love for his own good, the type who says “yeah, sure, whatever you want” and actually means it. He’s not a virgin loser archetype, he’s just kind of emotionally dumb, which is honestly more fun to watch. You follow him through this slow-burn mess where everything looks like romantic devotion on the surface, but underneath it’s basically one long build-up to him getting used, teased, and milked by every soft, curvy woman orbiting his life. The pacing is more like a long, lazy handjob than a quick fap: not much “gameplay” in the classic sense, since it’s a kinetic novel, but a lot of scenes where he’s sitting there trying to be a good guy while you, the player, are screaming at the screen, “bro, she is literally jerking you off with her eyes.”

The girls are the kind that porn sites keep putting on the front page because they know exactly what people click: thick asses that take up half the screen, tits that never learned about gravity, and this very deliberate way they move in the 3D scenes so you always get that voyeur vibe. There’s this one moment in the bathroom where the MC is just “accidentally” watching one of them shower, telling himself he should look away, and the camera just stays glued to her ass cheeks while the water runs down, and you know the dev was like, yeah, this is the real plot. Another scene has him on the couch with one girl asleep half on top of him, and she’s “unconsciously” rubbing against his crotch while pretending to be innocent, and you’re sitting there thinking, sure, unconscious, right, absolutely. The blowjob scenes go from teasing to sloppy without much warning, like she starts just licking the tip, talking shit, then suddenly she’s pushing him to the edge and not stopping, and the game really likes to hold on that moment where he tries to pull out and she just grabs his hips and takes the whole load inside, with that creampie close-up that lingers longer than it probably should. Vaginal scenes are not shy either: you see her riding him, her tits bouncing all over the place, her ass slapping against his lap, and the sound design goes completely overboard in a good way, like someone cranked the wet slider to 300%.

What I kind of enjoyed is how the “harem” thing doesn’t start as an obvious goal. It looks like a normal romance at first, but the boundaries keep getting pushed. One girl “helps” him relieve stress with a handjob while talking about another girl, then later that other girl is on her knees, trying to outdo the first one, talking with her mouth full and drooling all over his shaft. There’s this scene where two of them basically treat him like a sex toy, one sitting on his face, the other riding his dick, and he’s trying to talk about feelings while they are literally using him like a mattress. The teasing is constant: short skirts, bending over on purpose, thick asses pressed in his face, one of them casually walking around without panties just to see how long he lasts before snapping and fucking her against the kitchen counter. Masturbation is all over the place too; you catch them touching themselves when they think he’s not around, or he’s jerking off while remembering how her lips felt on his cock, and the camera does not cut away. Oral, vaginal, creampie, all the “finish inside” fantasies you’d expect, but wrapped around a guy who keeps saying he’ll do anything for love and then actually proves it with his dick. It’s horny, a bit dumb in a charming way, and very obsessed with big asses and big tits in close-up, which, let’s be honest, is probably why you’re here anyway.

This one feels like some horny fever dream written by a guy who watched way too many romance dramas and then said “yeah, but what if everyone had huge tits and zero shame.” You play this dude who keeps telling himself he’s doing everything “for love” while the game keeps throwing more women with big asses and soft thighs in his way like it’s testing his faith, and of course he fails every single test. There’s no choices, no pretending, no stat grinding, just you sitting there, watching his life snowball from sweet to filthy. It starts kind of cute and almost normal, with that slow teasing vibe, some accidental touching, a kiss that lingers too long, her pressing her chest into him while acting like it’s nothing. Then it escalates fast, like the script forgot about restraint halfway through and went, “ok, now everyone wants his dick and he’s suddenly fine with that.”

The voyeur stuff hits early. There’s this scene where he’s outside her room, door not fully closed, and she’s on the bed, phone on silent, panties halfway down, rubbing herself slow while whispering his name. Camera just stays on her hand working between her legs, the little wet sounds getting louder, and he’s there, stiff, breathing heavy, not even trying to look away. You don’t click anything. You just watch him watch her. Later you get him spying through a cracked bathroom door while another girl is in the shower, water running over her curves, her fingers sliding between those big cheeks, then slipping inside while she props one leg up for “balance.” It’s not subtle, but it’s hot, especially how the game keeps cutting between his face, red and guilty, and her face, totally lost in it. They even give you one scene where he catches two of them half dressed, playing with each other on the couch, one girl sucking on the other’s nipples, big tits pushed together, and instead of screaming or running they just smile at him and open up the space between them like “you were already watching, might as well join.” Real subtle, yeah.

Sex scenes are long, like old hentai OVA long. You get full-on oral where she’s on her knees, drool sliding down his shaft, her eyes looking up, hands squeezing his ass while she takes him deeper with sloppy, wet sounds that just don’t stop. The game loves making you hear everything, from the first shallow lick to when she finally gags around the tip. Vaginal scenes go even harder. There’s this one with her on all fours on the bed, ass high, back arched, cheeks jiggling every time he thrusts in. You get those slow pushes at first, just the head slipping inside while she shivers and digs her fingers into the sheets, then he grabs her hips and slams in all the way, skin smacking, her moans going from shy to full on “fuck me harder.” Camera angles focus on the part where his cock keeps disappearing into her, her pussy stretching, lips swollen and shiny, and when he finally finishes he stays buried, pumping her full until the creampie drips out around the base. They do that thing where he pulls out slowly and you see it leaking out of her, thick and heavy, running down between those big ass cheeks. If that doesn’t do it for you, nothing will. And yeah, it’s a harem setup, but it’s funny how they still pretend this is about “love” while he’s creaming in basically every girl who bends over in front of him. Priorities.

Love in this game is kind of a bad idea, and that’s exactly why it works. You start as this guy who already looks like he’s lost too many nights to Pornhub and horny thoughts, and the whole story just pushes him deeper. It’s not about saving the world, it’s about chasing one woman, then another, then another, until “I’d do anything for love” slowly turns into “I’d ruin everything for one more taste.” The girls around him orbit like planets with huge tits and thick asses, and he’s the sun that can’t keep it in his pants. There’s no choices, no pretending you’re a saint, you’re just dragged along while he stares too long at a girl’s cleavage in the kitchen, or watches soft jiggle under her shorts when she bends to pick something up, and you already know where it’s going. One moment he’s “just helping her out,” next moment her lips are wrapped around his cock and you can practically feel the warmth of her tongue because the camera doesn’t look away. It lingers. It likes to watch. The whole thing feels like you’re spying on a life that shouldn’t be shared, like having your nose pressed to a foggy window while people fuck on the other side and pretend they don’t see you.

I liked how the sex doesn’t explode right away. There’s this slow, dirty teasing that feels more honest than usual porn game stuff. A girl walking around in a shirt one size too small, nipples making tiny mountains in the fabric while she “innocently” stretches. A shower scene where he tries not to look at the curve of her ass, fails completely, then goes back to his room and jerks off, cum dripping on his own belly while he imagines sliding into her and filling her up. Later, that imagined creampie finally happens for real, and the visual of his cock pushing in deep and then pulling out with white leaking from her used pussy is almost tender, somehow. And still, it gets kind of stupid sometimes, like how easily everyone falls on his dick, but you forgive it because this is a harem fantasy trying to pretend it’s about love and not just “I want to fuck every pretty woman near me.” Oral scenes stretch on in a nice way, too, with wet lips, messy spit on the shaft, throats opening slowly around him. When he finally buries himself inside a girl and she moans with that mix of pain and pleasure, big tits bouncing while he holds her hips and thrusts harder, it feels like the whole game has been edging you for that one deep, warm, loaded moment when he finishes inside and doesn’t pull out. And the game knows you’re watching every second of it, like a pervert hiding in the corner with a hard dick and a guilty smile.
