Thats not what happens on my end. For some reason when I walk around, on occasion the pcs tummy will go flat and then after a moment or two revert back to being bloated. You can see what I mean much better in this video. I've also done some more testing and this also happens when I'm stuffed vaginally and anally.
Is there any way I can send a video of it? I've tried recording on my phone making a zip and posting it directly on here but it just dirty necks me and says the file is too large.
