Ok, so I remember hearing every so often that implants can make noise. Usually this due to air being trapped in either the implant or the surrounding cavity. I've read about this but never actually saw (or heard) any video of this.... until recently.
A model on Manyvid, Princess Berpl (super cute, bubbly, hot, with a nice set of 800ccs silicone tits that she's looking to upsize) had experienced this in December. Apparently while vacationing in the mountains, the high altitude caused air to be trapped in her breasts and caused her implants to slosh every time she jiggled them. There's even video of it in her ManyVid crush section (It's only $5 and well worth it!!) You can clearly hear the them too! My only disappointment is this is the only vid she made with the "sloshing." Honestly, I would have paid for an ASMR vid of just her playing with her tits and them sloshing.
Not gonna lie, an odd niche part of the fake boob fetish I have is when there's noise attached to boobs moving. Think to Kitten Natividad's "Taking it off". Every so often when she jiggled or bounced, they attached a "sloshing" sound to it. Honestly, I liked it because it really emphasized that her tits were fake. There have been a few movies here and there that attach either sloshing sounds or balloon sounds to boobs as a gag. Even Taylormadeclips and Bambi Blaze did growth vids with water filled rigs that gave that slosh effect.
I wonder if there are any more real world examples of girls with implants that make noise. It's definitely something I'd like to see/hear more of and would gladly throw money at. Especially if it's with some girl in the 2000ccs+ range. Anyone else?
