There's a real shift in quality between Vol. 1 and Vol. 2. The scenarios all tend to start the same, with Calvin taking photos of the young ladies, then easily talking them into nuzzling his tool. However, the ladies in Vol. 2 have it all over the ones in the first volume. They're more attractive, more energetic, and a lot more fun to watch. Not to say Vol. 1 is unwatchable, but it's a little lackluster. If future volumes improve as rapidly, this series may really amount to something.
