...that the both of them would become as dumb as infants, considering how completely and utterly brainless Amanda's decision was. Unfortunately the ring misinterpreted that wish and gave them the minds of infants. Within an instant, both Amanda and Samantha fell to the floor on their asses, dazed, and clapped their hands, laughing as if it were the funniest thing that ever happened to them.
"Well, they're more manageable this way," Joey thought. And he also realized that he had two women with whom he could do whatever he wanted with. Now that he had witnessed their transformation, he developed a sort of adult baby fetish. So he wished that they were in diapers, and their clothing disappeared, replaced with some adult-sized pampers, which was none too soon, since just then, Amanda let loose a torrent of urine into her diaper and gurgled.
Joey wished that he could lift either of them as if they were normal infants, yet still retain their bodies and weight (he worded it carefully this time so as not to mess it up again). Then he picked up Amanda and Samantha and carried them to a brightly colored nursery area he created from a mental wish. He set Samantha on the floor by some blocks, which she began stuffing into her diaper and rolling around, and then laid Amanda on the conveniently located changing table. Joey undid her diaper, removed it and threw it away, then grabbed a new one from a package of them that came with the nursery. Amanda thrashed around a bit at first, but then he squeezed both her naked breasts, which caused her to stop squirming long enough for him to put a new diaper on her. Then he set her down in a small swing and went to check on Samantha.
