You decide to go all out, so you start firing on any place you could think of. First you start with your butt, making each cheek swell to the size of beach balls.
"Woah, gotta balance it out" you say, aiming at your own chest. You held your chest as a round boob swelled and grew from it, followed by the other, each the size of basketballs. But you wanted more. Placing the breastinator under your new chest boobs, you grew another pair as big as the last, and then another just below either side of your belly button.
"Okay, thats enough for the torso now" you say, rubbing your 8 chest boobs, each began to seep milk with every touch. You then began on your shoulders, a boob sitting atop them like footballers shoulder pads, both larger then a basketball, you couldn't see left or right, but you didn't really care. You then moved onto your biceps, making them into big round football sized breasts, before making a pair of grapefruit sized boobs on the backs of your hands.
"Phew" you say, taking a minute. You feel the extra weight of the boobs, the milk sloshing about inside. "Right, time for my legs"
You fire at your feet, each swelling into a big round breast, your toes sticking out. Then you fire at your knees.
"Hmmm" you say, before firing at your cock, which began to grow rounder until it became a grapefruit sized boob. "Wow... feels great"
You then try to figure out how to do your back, before you have an idea. Aiming at the mirror, you manage to make a big round melon sized boob grow each side of your back, and another pair below it.
"Nice, now for my face I guess"
You aimed at the left side of your dimpled chin, swelling it to the size of a ripe orange, before swelling the other side. You shook your head, feeling the sensation of having boobs on your chin. You then fire at your cheeks, feeling your face swell up, until you had a boob each side of your nose.
You look at yourself, covered in quivering giant boobs, wondering what to do next.
