I never thought we'd be able to double tie Zoe's deep belly button, but look at us now. While filming the video where we hung weights from her tied outie, we finally figured out a way to tie out the deepest part of her belly button, and from that point on I thought... let's suck it out again! After we get it double tied, we use a couple of tools from our belly button fetish play box we've been putting together, including a tool that let's us easily put these thick, tight bands around her outie. She was up for the pain, and this play session left her belly button more sore and sensitive than it's ever been.
