(Okay, listen up... I want interesting stuff to happen in this branch, so try and make some good stuff happen instead of boring things that no one will want to add onto. Thank you.)
Since you're in the back and you assume the coast is clear, you try to take no time to hesitate, before running back to the Wish Mashine, but something happens before you can even unlock the door. Almost doubling over in the throes of a painful sensation focused on your entire body, but mostly in your crotch and chest, you practically rip your shirt and pants off to see what's happening. After you do, it's clear to see that your body is reforming. As your chest fills out to Baywatch-bimbo proportions and beyond, you notice the slit forming between your newly slimmed legs. As the pain subsides, you are taken by shock and start to check if what happened was real. Shooting your hand down to your crotch, you feel between your legs. Then, purely accidentally, a finger slips in. Shivering from the sudden sensation your finger brought you, you grab your breasts to confirm them, too. Grabbing and squeezing your nipple, milk forms at the tip and it sudenly hits you why you were a big-breasted woman. The wish you made gave you the udder of a cow and since cows are female, you got the "equipment" of a female, too. But the reason for the breasts, you conclude, was the super-sized milk glands you now have, thanks to the cow's "equipment." Quickly, you put your shirt back on (as best you could) and your pants back on, too. Unlocking the bathroom door and peering out, you don't see anyone around, so you run back to the wish machine. You get there safely, and fish another quarter out of your pocket and put it into the slot. What do you wish for now...?
