The Dark Prince's manga / #Cats(2)

Kuroneko Kareshi no Amaekata

Complete | Sakyou Aya , SAKYO Aya | 2013 released

Definitely one of my favorite series due to having enough of a storyline to support copious amounts of graphic sex.

Smoker

Complete | inoue satou | 2011 released

The last 3 chapters makes up a really cute short of cats and a couple falling in love. The first 4 are one-shot flings involving employees from the same company. Needs more sexy-time and romance...
