Inu ni Natta Boku to H Suru Onna-tachi 2

For some reason this shonen got turned into a dog.
At first he was just plain bewildered, but it turned out to be pretty awesome.
Now he's just living regular life.

His owner is his cute imouto who loves him more than a girl should love a dog.

Erotic comedy about dog and human bestiality, part deux!
Enjoy true little sister, classmate, teacher and the sexy neighbor...
