A short but sweet hentai. This hentai has two short episodes around 15 minutes in length each that follows a guy that is dating a curvy girl with glasses and also has a sister with glasses. The MC has a glasses fetish and proceeds to have sex with first his girlfriend, then his sister, and finally with both of them. While there isn't much more to the story than that, it's enough to keep entertained and aware of why events are happening. The art is pretty great with both girls looking sexy and very curvy with a decent amount of detail going into the background for ahentai. The animation isn't the strongest though and the only real issue I had with the episodes.

As for enjoyment, I quite liked this series. The sex and romance if fairly vanilla with no rape or extreme niche kinks either. The harem ending with the threesome was a nice bonus as a lot of series like to have just one on one action between MC and harem girls and never a group sex scene.

Overall, if you like girls with large breasts in glasses, then this is the anime for you.
