On the internet, usually, if anyone skilled in animation porn finds it, most likely, they will make cartoon porn of it. This has happened sooo many times that people now say that rule 34 is that there is porn of anything that exists on the internet.
Oh yea, the other day I saw a rule 34 of Ash and Dawn. STOP. Ash and Dawn is a common pairing, so of course we will have a rule 34 of it!
Oh yea, the other day I saw a rule 34 of Luke Triton and Ness. STOP. Luke Triton and Ness is a pairing most haven't thought of, and I have yet to see a rule 34 of it, so for the time being, this is an exception. If you do happen to see or make one, contact me at firstname.lastname@example.org :)
(Rule 34's brother in childhood smashing is rule 64
