Maybe he acidentally found the website and clicked on it? Like right now I clicked on your link and now it is saved to my history - but that doesn't mean anything just that I am curious.
I do no know anything about him, but even if he fantasizes about his sister - it's ok as long as it's fantasy. It's wrong once he starts doing anything. f he doesn't, there is no concern.

Don't jump to conclusions, and certainly don't bring it up with your girlfriend.

Maybe he thinks the girls on the site are especially attractive. Maybe he accidentally went there, as the above poster said.

My grandmother used to say "No cuque el diablo." Meaning "don't tease the devil" in Spanish. He may or may not have fantasies about her but if he does, its only one step closer to an action. The result? Ask millions of kids who have been molested.

You may speak to him but you may not speak to your girlfriend on this subject. Do a guy to guy discussion with him.

I know that I have looked at many things on the web for the shock factor, He most likely thinks its as gross as you do. But like a train wreck, it sure is hard not to look.
