Above the Clouds has some of the better humor I've experienced on this site. Jokes, puns, situational comedy, visual references, sound effects, and other devices make this game a very enjoyable comedy. It's so entertaining that I think it's worth checking out in spite of what I'm about to say: the erotic content is kind of a mess.
No sex scene ever feels earned. The sexual progression feels a bit like the author is following a formula of sexual beats, like, "Okay, it's chapter 2. This is where the protagonist should see the sister naked. Chapter 3: time for either a blowjob from a non-relative or hand stuff with a family member."
But it's missing the connective parts. It's missing any romance, sexual tension, or gravitas to build up to these scenes because every scene is just (admittedly amusing) comedy until it's time for the protagonist's dick to come out.
For example, there's a character who has barely interacted with the protagonist or shown attraction to the protagonist when she tells the protagonist he can hang out in her tree house while she's at school. While there, he finds her BDSM box. She comes back from school, he basically says, "I found your toys, slut", and she's just like, "Okay I guess you're my daddy now," while letting him put a remote controlled vibrator inside of her.--And of course, during the entire ensuing sex scene, the protagonist's sister is comically searching for the sound of the vibrator, again creating conflicting tones.
In conclusion, Above the Clouds is not erotica. It's a comedy game with some super awkward sexual content. That puts it at odds with me because I think most people play games with explicit sexual content for reasons they will not achieve here. However, apparently that "works" here a little more than it doesn't work, because it still gets 4 stars.
