Know where I can find Dexter?

[Cal]

Yeah so I'm watching Dexter (Showtime series) With my roommate and Netflix only has the first 2 seasons and I'm trying to find a place to watch season 3 and 4

I'm looking for a site that doesn't require any registrations or survey fill outs. Also streamed would be preferred but if its downloaded a play that's safe from viruses.
An added bonus is if you know where I can watch season 5 episodes when they finally air

Cuevana | Dexter: Our Father

That's season 3, episode 1; online streaming.
I believe you can find the rest by yourself in that site.
