Nico Robin hunting Vivi in a cave already sounds messed up, but this thing leans into it so hard it almost feels like some twisted fanfic someone coded after too many horny nights with a Crunchyroll tab open. The whole setup is simple: Vivi is caught, dragged off, and you’re pretty much sitting there watching Robin break her down in this dark, damp dungeon that looks like the kind of place Crocodile would pretend he doesn’t know about. There’s no fake morality, no soft fadeout before the bad part. It starts wrong and keeps getting worse, in that way some people pretend to hate but keep scrolling back to replay.

Robin here is not the smug “ara ara” tease from the show, she’s flat-out predator. She’s got Vivi tied up tight, wrists and legs restrained, body stretched just enough to look helpless but still on display. You don’t get that lazy “oops my clothes slipped” anime shit. This is ropes biting into skin, body pulled wide, that helpless little twitch when she tries to move and can’t. Vivi’s eyes are doing most of the talking; she switches between shock, panic, shame, then that broken half-lidded look when her body starts reacting against her will. That’s the part that actually hits: she doesn’t suddenly become a willing slut, there’s no cheesy “I always wanted this” line. It’s confusion and arousal mashed together like someone hit random on her brain.

The fucked up centerpiece is Robin growing herself a cock and just taking Vivi from behind while she’s trussed up, and the game really milks that angle. Doggystyle in bondage, cave walls, echo of skin slapping, that wet sound that’s just on the edge between hot and gross. You can almost feel Robin treating her like a toy she earned, pressing in deeper just because she can, yanking on the restraints while she rams into her. The creampie isn’t some romantic finish either, it’s more like marking territory, watching her cum spill out of Vivi while she’s still tied, hips jerking, thighs trembling. The lesbian twist should feel goofy on paper, but the way Robin grinds on her, kisses her neck, and then fucks her like a guy pushes it into that “this is so wrong I can’t look away” zone. It’s not gentle, it’s not fair, it’s not healthy. It’s dirty fan service for people who always thought the Alabasta arc needed a lot less sand and a lot more screaming in a cave.
