Cameras and VR-glasses

Placeable cameras[regular and concealed].

If a subject is nude while it knows it is being observed by a camera, it can gain pleasure via the exhibitionist fetish.

VR-glasses are a wearable item that show the subject wearing them the view from a camera, allowing it to gain pleasure via the voyeurism fetish[especially if the camera in question is a concealed one]. Which camera's feed the subject sees is determined by the player.

If a subject is wearing VR-glasses, it cannot see its local environment(duh).

If the player wears VR-glasses, move the view to whatever camera's feed is shown.

[the cameras' views don't have to be rendered unless the player is looking through them, in which case the player's 1st/3rd person view does not have to be rendered (especially since rendering multiple views in realtime is performance-heavy, and might be nearly impossible to implement depending on the underlying game engine)]

Optional 1: "streaming" a camera feed to earn a little bit of money on the side

[perhaps in the form of minor goals(that might not be what the subject likes)]

Optional 2: camera contact-lenses

A wearable that records/streams the point of view of the wearer. Counts as concealed to any subject that couldn't see them being put on.
