This fetish isn't for everyone because it is softcore and tends to be seen on girls with modest-sized natural breasts.
What I think is hot is when there's a chest-up shot of a girl in a bikini or a v-neck shirt, whose natural breasts are just big enough and supported just the right way, that when she breathes in/out or is moving her arms, it causes the gap between her breasts to repeatedly open and close hypnotically. Obviously this isn't seen on girls with very large breasts because they're always mashed together, and it doesn't look good on girls with stiff implants.
A good example is this clip of Naomi Kyle starting at 0:33 and moreso at 0:45:

Because of the lighting, there a bright/shiny (reflective) flat spot between her breasts, while her breasts near the gap are dark (less reflective because they're at a different angle), and so the opening/closing is very apparent.
