Ron could not believe his eyes as he watched the two girls go at it, he turned his head to see his brother staring as well with a boner forming in his pants.
Ron then started to look over the device in his hands "the girls really want this, I wonder what it can do" he thought as he started looking it over.
Ron found that this thing had all the stats of the four of them and as he watched some of them changed as he seen his brothers dick get bigger as he got more aroused.
Ron then decided to make changes in the device to see what would happen.
He made a few minor changes like turning off some awareness and the arousal of the girls but could see no changes happening.
Looking down he made another change increasing Max's breasts to a D-cup.
Ron looked up to see Max's breasts getting bigger "Holy Shit" he said as.
