Excluding the tags; hentai, shoujo ai, shounen ai, yuri, yaoi ...while including the "big ass" tag, these 34 manga are what MangaUpdates reveal.

Unfortunately I can't recommend any, and none seem ass focused, but hopefully this helps.
An anime that I've never watched myself, but comes to mind is Keijo!!!!!!!!

Aside from that, via the advanced search of MangaUpdates one of the best tags that you can rely on for sexy content is "Drawn by Hentai Artist".
Other more obvious tags/categories would be; adult, Fetish/es, etc.

The scanlation group Fap It Scans translate a lot of sexy manga also.
There's probably a few other groups and mangaka who you can expect sexy content, but I don't remember them...
