It took a bit of a while, but translated chapter 4 is out now!
There was little action this chapter, but it was still amusing (and filled with perverted gags!). And hey, we're already introduced to another of the Sins, so at least the plot is moving along nicely.
BTW, I had a good chuckle when I noticed that some of those fake princesses looked like they were enjoying themselves quite a bit following Meliodas' indecent orders.
