I don't consider this as flirting per se, but I do admit it was weird.
Well, it was
something: the turtle looked exactly like, well, what it looks like--and Seruria was more interested, in the moment, in sating her
succubus instincts than thinking of her master, Franz; she even wanted to meet again--and both were blushing.
The fact that she's a succubus narrows down what that
something could be, don't you think?
