It's the same girl from the author's other Futa GIRLS book, with redder hair: /g/1013030/3100581aae/
Looks like she's on the lookout to service horny older women as opposed to her kouhai this time, though. It was also nice to see more of the setting with all the other futanari fucking each other in the park. Hopefully the other two girls from the original work are also featured at some point in this series.
