No, not really, which is why I used it as an example. It's too much of wannabe LN shounen, and not enough about breast feeding, or lactation for that matter.
I mean, just imagine a season where some ecchi show about girls with huge, lactating tits getting milked. They could be 4-5 min episodes, with a quality somewhat comparable to the Manyuu OVAs. Why does that not exist? I mean, I'm sure it would be insanely popular.
I guess the bigger question here is: why are ecchi's so rarely about service? No one cares about some dumb plot, people watch it to fap.
