Yeah, boobs look a bit saggy bc of that overkill bounce. And it looks even more weird with cloth on, ain't they're supposed to limit the bounce for wooman?
On the other hand it showed especially during the first dialog, wasn't bothered much by it within the sex scene.
To stay on animation, during dialog these behave a bit weirdly. They stop half through waiting for us to skip the current text box, and going from animation to perfect stillness is weird, especially when hairs keep on moving. Special mention for the laughing animation, that goes directly to the uncanny valley, it's all kind of wrong, but it's sure looks tricky to make though.
On a more general basis, it would be nice to have more depht to the gameplay, as of now it's hard to figure out where this is going. Is it supposed to be narrative centered, somekind of RPG, a scene viewer?
On that matter i've tryed out many 3D games on here, well, every single one of them looked simply overwhelmed by the 3D engine. The ones that stand out the most were the narative centered. When devs are having a hard time fidgeting around motion, hitboxes, and physic engine, you can forgive when the gameplay doesn't revolve around it. It's a lot harder when it does.
Good luck on this dev, seems like you'll need it
