The rarest thing was when he smiles. Right now he was smiling behind her back, as he was satisfied by her reactions to his touch. He wouldn't kiss her quite just yet but he does massage her nipples with the fingertips seeing as how she was starting to relax quite visibly. However he had a bath to continue with her. As such he slowly stopped with tormenting her breasts and lets his hands slide gracefully over her stomach. With fingertips dancing lightly over smooth skin like as refreshing breeze, he continued to lather her figure up with soap. Of course it was a futile effort when she is submerged partially. A lesser man might have simply went straight for toying with her womanhood but Kaiba's hands pass over it and along towards her thighs. Both hands slowly knead over the right thighs outer and inner flank determined to soothe her aches and knots away. The point was this was to try and urge her to crave his touch. To feel a touch safer around him and hopefully associate him with a much more favorable mindset.
