Shawn answered the door, and smiled at Sue. She covered her temporary potbelly with her arms, and smiled back.
"Hey, Shawn, I was wondering if I could hang out at your house today?" Sue said, speaking softly as to not agitate her stomach.
"Well, sure! Come in." Shawn replied, moving out of the doorway. He caught sight of Sue's potbelly and frowned. He liked a little meat on a girl, but it looked odd to see her stomach like that.
"What is that thing you have there?" he asked, pointing at her gun as he closed the door.
"A toy! It's, uh, a squirt gun." Sue frowned and sat down on Shawn's couch as he joined her.
"But it's not that hot out today. Why do you have it?" He kept staring at her stomach.
"No reason. Do you have any snacks?" Sue smiled a little, hoping that as he turned she would get a good shot at him.
"Yeah, I'll go get some." Shawn got up and turned. Sue expected this, changed the dial to "Genitals" and shot him quickly.
Shawn felt an odd tingling in his pants and blushed. He must have been getting a hard-on, but why? He stopped moving, and the lump in his pants grew. It dawned on him that it wasn't a hard-on making his pants tight- it was his actual dick. He unbuttoned his pants and forgot about his guest. It kept growing, until it was a solid foot long. His balls were the size of melons. Sue let go of the trigger.
Shawn stared at his new manhood and smiled. It was perfect, the right size. Sue came up behind him and grabbed it. He immediately became hard and grew to a foot and a half long and Sue turned him around.
She turned the gun onto herself, and set it to "breasts" and plus. Her small, A-cup breasts grew and swelled into large DDs. Her shirt ripped open, exposing her breasts and now small potbelly to Shawn. She stopped when they reached EE status, and kissed Shawn.
He grinned. This was amazing- his big dick, her huge breasts. He was so horny, that he grabbed at her breasts and squeezed hard. Sue moaned, and dropped the gun once again. Shawn grabbed it, and aimed it at Sue. He set it to "weight" and plus. He made her gain a few pounds and stopped.
Sue had a small paunch, which spilled over her new, wide hips. Her breasts grew even more than before, each a foot in length. Her thighs touched and her ass went out a bit behind her. She grabbed Shawn's dick and rubbed it, pulling it into her pussy.
Sex ensued once again and Sue was filled with Shawn's cum. She moaned in pleasure, and came as well. Afterward, they lied on the couch, entangled in eachother. Sue changed her breasts into C cups and put on one of Shawn's old shirts. She kept the body fat, even putting on a little more. She enjoyed how full she felt, with Shawn's and her brother's cum, plus the weight she had on. Shawn fell asleep, like her brother, and she left his house with the gun.
She was enjoying this very much. She went home, and fell asleep.
The next day she had school, however, and forgot this when she woke up the next morning. She hadn't had her period yet, and she wasn't pregnant, however she worried about what everyone at school would think about her new weight and breasts. She shrugged it off, turned the gun on her breasts again and changed them into EEs. She was proud of them, and sneaked out of the house away from her parent's prying eyes and went to school.
At school, she could see all the wonderful possibilities of the gun. Getting revenge, having sex... And then she was interrupted by a rude girl.
"Wow, you've gotten fat! I'm amazed at how much you can put on in one night. You ugly pig, not even your huge breasts could save you from being so huge! I mean, really, did you eat twenty pizzas or something? That is disgusting." She walked away, smirking. Sue fumed. Making fun of her perfect figure, and calling her ugly! Sue would show her, by...
