Yeah, not gonna lie, I normally am fine with furry content, but those dogs just didn't look right.. The sex was fine, but that face, and the weird blurry tail wag just didn't look right at all. (The children in diapers is what really gave away that someone paid a little extra for this)
I wouldn't quite say they're like a cancer to H games.. More like lice.. Not every game has them, but the ones that do, got them bad.
But hey, if furries are more willing to pay money to see their desires put into a hentai game than other people are, then more power to them. Can't blame them for being ambitious.
