8 XXX : Lamia

As an aside, just for a goof: This is actually rather dangerous - scales are rather rough, they need to be in order to move. This is a very easy way to cause tears in the vaginal/cloacal (depending on your canon) wall. Of course, we can just head canon that there's a well lubed wrap on the tail... so no prob
Bless ??
