Behold an overcompensating mad scientist in 'Scooby Doo and the Joy Mystery of Gay Tentacle Porn' who uses his crazy invention to fuck Fred and Shaggy with purple slimy tentacles.

Archie Fucks Jughead

Whenever Jughead wants a burger, Archie is there to put his meat between Jughead's buns.

Fred Blows Shaggy (and a Villainous Guy in Rubber Suit)

A scene of Fred and Shaggy having a gay threesome with a costumed villain raises... erm... raises a question. Is it appropriate to yell 'Zoiks!' when you can't hold it any more and cum misses your friend's mouth?

Batman and Robin
