I'm not really into zoo, but catgirls/catboys have decent sets

I say canine cock but ONLY if it's attached to something humanoid

I guess it's not much about the genitals but the beast or monster dynamic with a human girl. I do like a few specific cocks. The Bowser dick here is in my top 3 and is so fucking hot.

I do like horse cock porn, primarily due to the ridiculous size and amount of cum. Having a woman getting completely stuffed is fun :D

Human, because I'm not a zoophile.

No thanks.

There's no cock like horse cock

Neither, horse asshole.

If you mean in real life, fuck no.

I don't find them sexy, the I've got to respect the leapord slugs. Sex becomes a trapeze act performed in midair with (proportionally) long prehensile transparent genitals.

Last thing I'd expect to hear while blindly clicking links here is David Attenborough, but I'm glad I did. Holy fuck are those slugs thoroughly majestic. Imagine if your dick could join with another's to form some huge tulip structure in midair (while trapezing from a string your own fluids no less). Some avatar shit fr.
edit: I forgot what this thread was about. Anyways my favorite is the leopard slugs.
