I have yet to see the first season of this series but saw the second season, which is called 'Sora No Otoshimono Forte', on CrunchyRoll. The story follows Tomoki Sakurai and various 'angeloids' angel-like androids from world known as The Synapse. While there is a story involving the angeloids that live with Tomoki battling to protect him from those working for Synapse most episodes are intended to be comic rather than dramatic. These comic situations almost entirely revolve around Tomoki trying to see women undressed or trying to grab their breasts; his initial success is usually followed up by swift retribution though.
While there isn't actual nudity on show this is clearly a fan service show; no opportunity to show jiggling cleavage is missed and some of the costumes worn by the angeloids don't cover very much. This led to the series feeling a bit sleazy at times however some of the situations were genuinely amusing, the animation looked good and I liked the character designs. Talking of character designs they are frequently shown in 'chibi' form, in fact I think Tomoki is shown in this form more than his regular form!
If you are looking for something deep give this a miss but if you just want a basic plot and a few laughs then you could do worse. These comments are based on watching the series in Japanese with English subtitles.
