Yuka was thankful for the soft touch on her arm as it did indeed do a good job to reassure her.  She tried to speak to thank her kind friend, but then the realization hit that the three of them were all naked and very much alone in the hot tub, and she was being gently touched on both sides.  One a kind reassurance, and the other more flirtatious.  Her blush then only deepened and she nervously bit her lip as she scooted herself along the bench to all but disappear in the water, her head now the only thing not fully submerged.  'Stop thinking things like that about your friends!  If they thought of you like that they would have said something by now...  There is no way they haven't seen the way you have looked at them!'  She said to herself desperately trying to get herself under control.
