True, in some photos from Lilly's twitter and patreon accounts she did indeed look a bit larger, yet we do not know when they were taken. Date posted does not mean date snapped. However, these AVN photos are days old and there is no way those are filled to 5k.
Never mind comparing Lilly to Chelsea. In photos with Lilly next to the petite model, it's clear her implants are large, they are not the purported 4 or 5k regardless of what she may claim.
Mistress Rhiannon, by comparison, said she was 4200cc and her chest was so massive as to put Lilly to shame.
