You look around for a bit, before finding another couple to change.
The girl has long, slender legs, making her a bit taller than her boyfriend. He has the build of a swimmer, with a thin, lean frame.
Deciding what to do first, you switch to 'in' and aim at the girl with a high pink. Instantly due to the high setting, her clothes became much sluttier. She now has a tiny skirt on, and a small tshirt that is only covering her boobs. You switch to the 'or' setting and narrow the beam on the highest blue. Centering it on her crotch, you hold it for ten seconds. A noticeable bulge appears, and because of the constant exposure, keeps growing. You stop once 'her' cock falls out of her thong and has no chance to get back in. She now has a dick that seems to be 14 inches soft and balls the size of large oranges.
Turning on the boy, you just blast him with the high pink 'or' to make him still able to have sex with his girlfriend. You also use the beam to give both of them larger breasts.
You laugh when they stand up and walk away, one with a flopping cock slapping her knees and the other with massive breasts bouncing freely on his chest
