Looking for this type of anime?

hi guys... So i'm basically looking to watch a senseless anime, just for some fun and too kill time... So i'm looking for something that has a ridiculous amount of ecchi/fan service in it...

Beyond that, i'm looking for anime recommendations... It doesn't matter how many episodes it has, or how long ago the anime came out... It can also be any genre...

^if you do reccommend something, please let me know whether i should watch it dubbed or raw (i understand japanese so i don't watch/need subs) and also if there are any OVA's (original video animations) and or movies that are associated with the anime...

^an example:

fairy tail anime has 1 movie plus 5 OVA's (7 if you count fairy tail x rave and the movie prequel ova)

thanks for your time! Have a good day ahead :)
