Years ago, ChuB-lip had that functionality with Custom Maid 3D 2, which later received VR support. Well, kind of. You still have to move it, but it syncs the animation, rather than in reverse. Self-moving onaholes are not very good; they have to be very loose so that the motor is strong enough to move it.
