I could be wrong, but didnt Moka actually comment the taste of his blood had changed a bit at one point?

I'm half of the mind she [O.Moka] still sucks his blood partially because she's addicted and her own personal needs/avoiding anaemia, but also partially because of how she feels about him. (She may not have him per se as yet, but she can at least have [some of] his blood! Seriously, I wouldn't put it past a woman to think that way given some I've known!)
