Innocent Expression → Hypnotized by the Viewer

Next, I decide to tweak the scenario again a little and replace 'Innocent Expression' with 'Hypnotized by the Viewer' to add a bit of spice to the encounter.

The end of the corridor retreats back until it seems just a few yard behind the twins, and the framing of the arch and the height of the lamps behind them is really messing with my sense of scale. As for the twins themselves...

Their visible hands slide toward one another, each sister's hand reaching around the swell of her breast and into her own cleavage. Meanwhile, the metallic bras 'supporting' their breasts have vanished entirely. Their tits spill freely outward, supported only by their arms as their shift in place to smile guilelessly my way.

The steel of their bikinis turns to a black, leather material, their hair lengthens. Then the hair of the righthand twin becomes just a little less red and more purple, although both still clearly have pink hair. As the steely halter straps on their collar turn thin and black and a pink gem dangles itself from each collar's center, the changes cease.

That did much more than I expected, and yet also less. Their expressions still seem relatively "innocent" for example. More than before, even. Something about their eyes feels a little off: a little dark, but beyond that there's no clear visible sign they're "hypnotized." Even so, I'm absolutely confident they are, and that they're liable to follow any given instructions I give them.

Well, I suppose I shouldn't expect something that only really messes with the mind to be clearly visible anyway. Now...
