This link has a bunch of SasuNaru doujinshi in English. But the second one you might have to download a software... but it's still free.
For this link:
they changed the site recently so i can't tell you the exact directions to find it, but type in naruto in the search box and they pull up a bunch of SasuNaru and some KakaIru ones.
The next link:
is pretty explanatory. Just choose the ones that say SasuNaru and english. But you MIGHT have to download something called winzip...
There's probably a fair share of lemons in there... hope you don't mind. (Personally I love them XD)
I think most of them are SasuNaru but there may be some NaruSasu as well. (Nowadays I can't even stand SasuNaru. Not because I think Sasuke's an uke, but because I strictly believe that Naruto is a seme.)
