Cream often exhibits a dominant and somewhat harsh demeanor publicly, but privately, she deeply enjoys being submissive and experiencing humiliation in bed. Essentially, she requires BDSM to fulfill her sexual needs.
Black, who one might assume to be the ideal dominant partner given his intimidating appearance and demeanor, actually doesn't naturally fit this role. He generally views sex as merely a form of physical satisfaction, often engaging in it quickly and dispassionately.
However, his relationship with Cream is quite different. He tries to meet her desires, and even though he sometimes shows disinterest or even discomfort towards her sexual preferences, he finds satisfaction in fulfilling them. Nevertheless, this interaction often leaves him with mixed feelings. While he does participate in the BDSM activities Cream enjoys, he sometimes feels guilty or conflicted afterwards, especially about being aggressive towards her during sex. This internal conflict stems from his genuine feelings for Cream, which introduces an emotional depth absent in his prior casual encounters.
