MUCD-094 - Doggy style 2 of pure beautiful girls in pure uniforms

I usually expect a certain level of quality from the Muku compilation series, so I bought this with high hopes. However, despite the title being 'Doggy Style,' it includes so much 'long buildup' leading up to those scenes that it feels unnecessarily drawn out. I thought I'd be able to watch 18 people in a row for 8 hours focusing only on doggy style, but the content is too thin. I usually agree with Muku's production policy and rarely feel like I've wasted my money, but this one was a bit disappointing.
