You decide to experiment [cue thunder & lightning with evil moody organ music.]
You spin the dial-like nipple on your right breast, noticing it stops with a click that you can feel, rather than hear. You put it back on it's original setting, 0, and start to twirl your other nipple. This one is different, because you get the "clicks" like on your other breast, but only between the D-0-I settings. The dial moves smoothly through the thickening line to stop at it's end.
And nothing happens again.
You reset that nipple back to 0. and twist your other nipple to BR. Then you move your left nipple to I. Now something feels odd. Your breasts have seemed to have slowly grown larger. You try to move the dial on your right nipple, but it won't move. You move your left nipple back to 0 and try moving your right nipple again. It now moves.
With a little more experimentation, you can figure out the codes:
BR - BReast
BE - BElly
BU - BUtt
BO - BOdy
I - Inflate
D - Deflate
You find that you can inflate or deflate each area as you please, but you shy away from the BOdy / Deflate option for now.
So, how shall you entertain yourself?
