On the internet, everything vaguely dog-like has a big, thick penis with an even bigger, thicker bulb at the bottom of it. I’ve heard it’s perfect for prissy subs everywhere as you love-fuck them into a drooling mess only to ‘tie’ them at the end as you howl your alpha-dominant status to the echoing world of your 10ftx10ft, $1500/mo roomapartment.
I think Ian M. Banks (‘The Culture’ series) already had that, unless that’s specifically what you were referencing. Though humanity wasn’t a part of The Culture, as explicitly explained when they were viewing us like apes in a zoo, so the ringworlds with primitive cultures on them that had AI machine minds tending them weren’t from the wake of humanity.
