Care to explain what you mean by "anatomically correct" bulge?
Not bothering to look up examples but it has to do with the pelvis being a bone and not a lump of rubber, the bulge should start further up.
Actually lazily looked up an example:

mancuskaj is correct though, Pleasuree3DXs depiction of bulge doesn't take Emily's pelvis into account. Realistically it should start higher up on her stomach. Not that I'm complaining, either way is hot. Part of fapping to 3D renders is suspension of disbelief anyway.
Yeah, this is what I meant, thank you. This scene however jarred me out of the suspension, I was looking towards Emily finally taking it and then it's just cheapo rubber deformation.
And lilijunex actually has a (paywalled) vid where she explains how she takes them so deep, basically there's kind of a pocket in front and behind the uterus (
