Iku seemed to be able to feel the change in Ume before she saw it, and she brought her hand away from her thighs.  Collecting the dildo and giving it a spin to test its weight, she held it much like one would hold a dagger to be thrust into the heart of one's enemy...before using it to gently probe at Ume's lower defenses.  She decided that Hiro could move his hand out of the way or find out the hard way that the dildo express was ahead of schedule!  Alternating between poking around like a lover trying to find his mark and teasing Ume to arouse her, she said, "are you sure?  I can give you a little, but you didn't want anything before, right?  I really should respect your wishes, as your friend and teammate."
