15 Bishoujo Hyouryuuki, Rescue Me! Recommendations
- A guy surrounded by a harem of girls
- The girls are each different and fit into different archetypes
- The main characters are alone on a beach/island setting
- Rescue Me! is borderline-H while 15 Bishoujo is a hentai
These 2 are very similar. Guy plays innocent, but gets sexually harassed by a harem of girls. Both got beach scenes. Lots of perverted situations and sex.
