Neuro/Splice [v0.03.0 Ch.4] [FlimsyLegs]

May 19, 2026F95

FlimsyLegs’ fourth AVN. A story-rich sci-fi thriller with a body-swap (gender-swap) and BDSM theme. Neuro/Splice starts when a terrorist group known as the Veilbreakers successfully plant a computer virus in the NexaCorp mainframe, threatening to spill the corporate secrets to the world, before triggering a catastrophic meltdown. The culprits straight-up refuse to reveal how to safely removed it, and time is running out… Ryke and his team form a mad plan: Infiltrate the mixed-gender maximum security prison where Clyde and Eric are held, pretending to be Cassie, and learn the truth about the virus. To do so, they need to use an experimental procedure known as Neuro-Splicing, transferring Ryke’s consciousness into Cassie’s body.
Ryke (in Cassie’s body) is thrown into prison, and a dangerous underground world, in an attempt to learn how to stop the virus. Inevitably he stumbles upon truths about NexaCorp that makes him question everything he knows. Meanwhile, Cassie wakes up in Ryke’s body and finds herself in a unique position of power to learn more about the NexaCorp from within its own ranks…
More Info:

In Neuro/Splice, we follow dual protagonists Cassie Marlowe and Ryke Voss, two sworn enemies of opposing factions. Cassie belongs to the Veilbreakers – an outlawed group of truth-seekers who are convinced that NexaCorp is hiding something profoundly important about the state of the known world. Ryke works for NexaCorp, as a police officer, and has a personal reason to take down Cassie and the Veilbreakers.

Just like my other games, the focus will be on BDSM. This early teaser demo does not yet include these scenes, but you can expect to see a lot of device bondage, rope, whips, spanking, blowjobs, vaginal and anal sex, and a whole lot more. All the kinky things you’ve come to love from my games! What’s unique about Neuro/Splice is that you get to experience the BDSM from either the dominating male’s point-of-view, or the submissive female’s point-of-view.

MC Cassie (in Ryke’s body) can have kinky bdsm sex with Ryke’s wife Marie. MC Ryke (in Cassie’s body) can have kinky bdsm sex with Cassie’s husband Clyde. It’s up to the player to decide if they pursue these paths.

Neuro/Splice is heavily inspired by works such as Face/Off, set in a dystopian sci-fi setting.

Multiple protagonist is planned to be handled the following way: Players play as both Cassie and Ryke, who at some point in the game swap bodies (gender swap). Sexual content in both paths can generally be ignored/skipped, if you prefer to see only FMC or MMC sexual content.
