It is indeed more of the same and whether you like it mostly depends on whether you liked the first part. That doesn't mean that it doesn't mix things up a bit. For one, both episodes focus on a new character, one rather contrary from the other. The first one has a mature Japanese, always seen in kimono (except when she's naked, of course), while the second features a dark-skinned, technologically-inclined foreign student. Both are futas themselves, leaving Akane as the sole non-futa (and even that gets played with).
While the first episode is rather standard, although is has semblance of a more serious plot and hot springs are always nice, it is the second one, where things get different. It features a rather forced sex competition between the club and the foreign girl, a few strange gadgets to support it and some rather odd sex acts (especially the one featuring the foreign girl's foreskin). Not everything might be everyone's taste (I for one didn't care much for Akane's "toy"), but it sure manages to set itself apart quite a bit.
Visuals and sound are the same as the first one, for better or worse. Overall good, but nothing outstanding.
Overall, it's a good successor to the first Futabu, that features everything that made it fun without being too same-y.
