    ●STORY

    Big brother is always doing weird things to me.

    When I come home from school, he’s always there, a shut-in waiting for me.

    If I don’t obey his orders, he hits me, so I do as he says.

    Recently, while I’m at school, he’s been making strange devices in the garage and pulling pranks on me.

    He calls it a “triangle pony.”

    He seems happy making boards bite into… that place.

    ●FEATURES

    Editorial Review

    This is an extreme BDSM simulator that positions itself squarely in the niche intersection of incest roleplay, mechanical torture devices, and domestication fantasy—a combination that pushes past what most mainstream adult game platforms will host. The core appeal here isn’t narrative depth but rather the crafting system that generates variable content based on player configuration choices.

    The distinguishing feature is the customization mechanic: players design triangle ponies (a BDSM device involving forced positioning and restraint) with different bite angles and mechanical properties, then deploy these creations against the sister character in a domestic captivity scenario. This systems-driven approach to content generation means replay value is theoretically high—different configurations produce different CGs and story branches. The synopsis emphasizes the brother character’s engineering obsession as narrative framing for what is fundamentally a torture-device construction game. The fact that visual outcomes shift based on mechanical design choices gives players a sense of agency within a deeply coercive fantasy framework.

    The production philosophy here is unambiguous: this work makes no attempt to soften its subject matter through euphemism or narrative complexity. The tags read as a checklist of extreme content boundaries, and the synopsis doesn’t flinch from describing non-consensual domestic abuse as the foundational scenario.

    This appeals exclusively to players seeking extreme BDSM content centered on incest, captivity, and mechanical humiliation without interest in character development, plot sophistication, or softcore romance elements. The appeal is purely fetish-specific.

    For anyone outside this narrow window—which is most players—this work offers nothing. For those within it, the customization system provides structural reason to engage multiple times. A specialist product executing exactly what it promises, without apology or compromise.
