You decide to make yourself 100% female so shopping is easier. You put the pink light on its brightest setting and shine it on your upper body. The fat on your stomach is sucked in and disappears; a pair of D-cup breasts sprouts from your chest; you lose muscle mass and become more slim and slender; your features soften and become those of a 21-year-old woman; and your hair extends down to your shoulders and turns blonde. Your clothing has changed to a revealing, and frankly slutty (although that doesn't seem to bother you...) tank top.
You look at Gene, thinking to change him as well so you can shopping as a couple of normal girls... mmm... he's hot. You realize the bright pink light must have magnified your sex drive, as you feel an intense desire for Gene. You suppose you ought to switch yourself back to normal, but hey... what's a little fun? Quickly you shift the light back to bright blue and shine it on his lower body. His legs gain muscle, his butt loses fat and gets tighter, and his package presumably returns in all its former glory. His clothes shift back to how they had been before you changed him.
"Are you done, babe? Can we get going?"
Babe? He called you babe? You must be going out! You're his girlfriend! This might be fun....
