Clicking on the tab to see the list of breast transformation he could see a number of things. Looking at the size he could see that instead of entering the size he wanted into a blank spot, the sizes were a list.
Curious at the cup sizes, Jay read that Rain's breast cup size was C. Scrolling down he saw that the largest size on the list was a K. Choosing to see how they looked on Rain he choose it.
Rain suddenly felt a her breasts growing. They grew and grew and grew. When they finally stopped, her shirt had ripped open revealing the largest breasts that she (or anyone) had ever seen.
Now Jay was getting really excited. Looking to see what else he could change he saw "nipple size". Rain's were only 1 inch in diameter, with only 25% arouse and 10% sensitivity. He changed them to be 2 inches in diameter with 90% arouse and 100% sensitivity.
Rain saw that her nipples were now growing, after stopping they looked huge, but that wasn't her biggest problem. She felt so much stimulation from just the breeze on her nipples. Getting up Jay touched one and immediately Rain nearly had an organism. "So much stimulation" she thought with trouble.
Things were not over for Jay as he looked at the other tabs.
