Bart Simpson in Bondage

Bart Simpson has been our favorite bad boy for nearly thirty years, but he's not exactly prime erotic fantasy material: ten years old, with a nondescript cartoon physique.

But fan artists artists have obligingly added a muscular physique.

And aged him into adulthood. 

And given him boyfriends.  Artistic depictions of juveniles aroused or having sex are strictly forbidden in the U.S. (people have gone to prison for it), so artists must be very careful to indicate that Bart (and Rod and Todd) are adults. 

Regardless of whether the act is consensual or not.

Other Simpsons characters have gotten their share of fan art, but it's overwhelmingly heterosexual.  I did find Snake being manhandled.

And Sideshow Bob's brother Cecil, who appeared in just one episode.
