Everyone knows their tail comes from the tail bone at the base of the spine.
Does that even look like its originating from the base of the spine lol .. More like originating from the pantsu XD
Maybe the artist had in mind one of those butt plug tails? ( ̄~ ̄;) I've seen those in several anime images, albeit normally more explicit ones.
A plug tail would leave a bulge in the pantsu that you'd at least see in the edge it exits them
tail from her 'asshole' (butt) ?, defecating ... how can she do it ?
