rerun119 tbh i think that first scene might be a bit of an optical illusion because it looks to me like she IS propped up quite far on one of those wedge-shaped sex pillows, but because they have a white sheet over it it kind of looks like a normal pillow on a bed. That being said that looks like a pretty good angle and i've always been a fan of the Wankz/MilfVR missionary angles.
Maybe the problem with other scenes is having the camera too close to their face? With the medium distance in that Jenifer White scene i can just zoom the camera in if i want a closer view and it still looks fine, but in other scenes when they put the camera too close i can feel a bit cross-eyed and if i zoom out it ends up looking weird.
