I tried cheating it in, but that didn't really work. As far as I'm aware the only easter egg on cam 6 is Wolf Link and Midna from Twilight Princess. There is no sex scene for these two, and there is no sex scene for any secret character other than golden freddy.
p.s. you could just reply to my comment on the game itself
edit: you probably mean Toriel. There's still no sex scene but there's plenty of "content" of her online
