Jon could almost laugh he was so happy, although it might have been caused in part by residual giddiness from the magic. He was so happy he jumped up in delight, only to be brought back down to earth when his boobs flew up and the impact on his foot forced him to swallow down a howl of pain. Right, he should probably take of that.
He hobbled back over to his bed and began a self examination of the damage. Holding his foot in the light from his nightstand, a task made more difficult by his boobs obscuring his view, he realized just how badly he fucked up. While nothing looked broken, no toes protruding at awkward angles, the whole thing was already swelling up in a brilliant shade of purple. There were also some minor lacerations around the big toe, but there was only a small trickle of blood building up at the surface so far.
At first Jon's first aid training from summer camps kicked in, but before he could try to hobble to the bathroom he slapped himself on the forehead for being an idiot. The stupid magic bra was what had gotten him into this mess, so the thing should damn well get him out of it. And he had obviously figured out how to use the thing, because magic was the only reason his mom wouldn't have come into the room to check on her son. All he needed to do was feel that emotion again and...
15 minutes later and it was clear that he didn't quite know what he was doing yet. Jon might know what the method of magic was, but that didn't mean he knew how to engage it. Emotions were slippery things, difficult to control and even harder to direct. It was hard enough to build up a sincere emotion and even harder to focus it into exactly the right feelings he need to activate the bra. Finally the frustration at his own failure rose up within him, and as that tide of emotion swelled the magic came to life.
The feeling of the magic leaving his body was less intense this time, which was probably because the boobs that contained the magic were smaller. However, the intensity of sensations wasn't diminished because he simultaneously experienced a rushing sensation up through his body emanating from his foot as the skin stitched back together and the swelling was reduced.
As soon as he recovered from the afterglow Jon grabbed his foot to examine it. Though he had no reason to doubt it, he was happy when he confirmed that his foot was as good as new. In fact, it felt even better than before, almost smoother, most likely because the skin had been freshly magicked up. He did notice that the shape looked just slightly different, though he attributed that to a trick of the low lighting.
Jon also noticed that the breasts which just a few minutes ago had been C cup monstrosities were now reduced to itty-bitty A cups. He hopped off the bed and gave an experimental bounce, and was thrilled by both the normalness of his foot and the fact that the bouncing of his breasts has almost entirely dampened by the magic sports bra. Content with his own success and satisfied that he knew how to deal with any future growth from the bra, Jon curled back upin bed and quickly fell asleep, emotionally exhausted but somehow also happy.
Not five minutes after Jon was out, the clock struck 4:00. The magic of the bra activated again, causing his breasts to swell up to B cups instantaneously. But the bra had another secret to reveal. Because Jon hadn't emptied his boobs all the way down to the zero magic level, the magic retained memories of his previous maximum size. So the bra didn't stop growing at B cups. It shot right past the C mark and straight into D cups. If Jon had thought the previous size was bad, he would have been shocked to see the mounds of flesh protruding from his chest now. Fortunately, he had fallen asleep on his back this time, so the sudden sensation did not wake him. He slept on, unaware that his breasts, even contained as they were in the bra, still tented the bed sheets by a good four inches
