Magical boobs of course!

"I wish I had magical boobs. What!" I really had made a strange wish. I waited for my chest to hurt and a pair of tits to grow in, but nothing happened. Tentatively, I took off my shirt to look at my chest, but nothing was different. My nipples hadn't even changed. Even as I thought that, I felt the change like some sort of demented delayed reaction.
A pink mist started to spray out of my nipples with a hissing sound like in a steam engine. Before it had stopped, I heard this weird gurgling noise like water stuck behind a clog. That's when all heck broke loose.
A pain erupted across my chest like the skin was being torn apart from the inside. The pink mist descended on it though, and the pain all but disappeared. ' I watched with morbid fascination as the skin beneath my nipples started to expand. The gurgling sound was replaced with the sound of a bottle being filled with water. When the sound stopped, so did the growth, leaving me with a pair of A cup, female breasts.
