A real SM documentary where the pure and cheerful Miku Otsuka learns the pleasure of being tied up and abused, awakening her latent M-side! Writhing in ecstasy from her first anal experience, she eventually forgets her humanity and becomes an obedient, loyal dog.




















The actress is great... and the natural hair is a plus, but after finishing it, I'm just left with '???'. It's rare to see a work that wastes its actress this much. Also, the front-handcuffing is the worst. Why would you tie her up in a way that covers her breasts? I don't get the appeal.
The actress is cute and I'd like to recommend it, but given the title 'Service Dog,' the actual content felt a bit underwhelming.
The actress has an average build—not great, not bad—and she's neither a beauty nor ugly; she feels like a regular office worker in her late 20s you'd pass on the street. Her acting isn't particularly good, but that actually adds to the amateur vibe, which I like. Plus, she's completely natural down there—no grooming at all—which makes it feel even more authentic. The excretion scenes aren't obscured by weird mosaics, and there's even a golden shower, so fans of this genre should be satisfied. If I had to nitpick, it would've been even better if there were some internal ejaculation scenes.
The background is terrible, looks like they filmed it in some random rented office building. It's supposed to be some kind of puppy-themed SM play, but there's no sense of affection or 'training' a cute pet, so it was just boring. I ended up fast-forwarding through the whole thing.
