The first sign that Izu might have been a bit surprised and is gasping for air is the quick switch Derple can feel of the elf going from being cradled against her breast to a quick attempt to pull back that's well forshadowed by the feeling of the elf's rough lips rubbing against a few patches of sensitized tit-flesh.<br/><br/>Fortunately, the rather harder taps of Izu's cyber-arm are on more normal flesh, because the heavyness of the hand and the both hot-and-cold finger tips would be quite distracting in a different way than just being a bit unexpected. The more normal hand seems to have found its way from just below Derple's other breast to on it. The realization makes Izu try to signal just a little more urgently, and Derple gets a little knock of soft elf-leg to her thig- wait.<br/><br/>That's the wrong spot for the elf's leg to have touched, right?
