Not only is College Humor's Mario and Peach sex tape extremely not safe for work, it will change the way you play Super Mario Bros. forever.
I'm going to say it again, in case you miss the tag, and never read the first sentence of any Kotaku story. This is not safe for work. So not safe that even I got a bit blushy at one point and had to look away. Nice use of sound effects and Boo, but this is probably something that shouldn't be seen ever by anyone.
Having said that, here you go.
