Irua is such a wonderful author. The three stories are great, well written and beautifully drawn, and also they are VERY different in theme, style and atmosphere.
The first one is pure sleaziness, with raw lust, corruption, cheating and a bit of ntr. Sexy things happens, several times, all the way.
The second one is pure wholesomeness, cute and fluffy, and will probably put a big goofy grin on your face.
The third one is kind of dark and deals with weighty social issues. The yuri is mostly subtext, and actually someone who's not into it could probably deny that there's yuri at all.
Of course I loved all of them.
