Hellooo...

Looking for a yaoi manga with supernatural themes. Looked up the 'supernatural' tag and didn't want to go through 795 pages, so here I am... It was about some demon-type guy working in a bar or something. I think he might have been a succubus, but I might be wrong... The premise was something like he would have sex with his clients (as both seme and uke, depending on the client), and hypnotize(?) the client into thinking he was the client's love interest or something like that; ultimately culminating in client dude realizing his feelings for that person... I remember one specific scene where the client (I think he was an uke) was like (paraphrasing), "What the *&%$ are you doing here, Cake-man?" And his face was all cartoonish and exaggerated and it was actually really cute and funny. I think demon-dude had black hair, if that helps. Please and thank-you in advance. ε=ε=(ノ≧∇≦)ノ
P.S. Katie, if you see this, I miss your face! <3
