I cannot figure out how to trigger the STCP-1471-A cowgirl scene in the sim chair, it always is a blowjob instead.
From my understanding, the Sim chair is for enemies that fight to dom you, without the fighting. It does not let you simulate non fight sex, such as Mal0's cowgirl, the first glory hole ghost, or Catalogs "Game."
Maybe the option to scan and simulate the non fights might be added in a future update, but I don't think it would happen because of Arianna's Parlour. (Why sim and get fetish, but not get paid?)
The other enemies that have two scenes listed in the chair are Velora, who has two separate buttons for each scene, and gym rat/ST patrol droid, who really have one scene with a variation built in. Since STCP-1471-A didn't have two buttons like Velora, I expected the scene to have a "second phase" like the gym rat and ST patrol droid do. Otherwise I have no idea how to even view the cowgirl scene since I didn't find it through normal gameplay.
