Haha that PEDO Master laying her hands on her lil cute animaly maid! O_o... But if it's TRUE LOVE i don't have anything against this! >~<
That!
Meh.. if it was real and not some loli fluffy cute story, Master should have waited some kind of age of consent before laying her hands on Mel.
I have nothing against them sleeping in the same bed and cuddling, but the kiss is a bit too much, because Mel obviously knows that it's somewhat "wrong" since it's a secret.
On the other hand, this is fluff and the fact they have some races with animal ears is made so as to distance it from our reality.
So I will go on the premises it's all OK in that parallel universe.
