"GIGGLE!"
James covered his mouth quickly. He trembled in disbelief after hearing such a girly sound coming from him. He felt different almost like he was lightheaded. He shook his head to clear it but the cottonballs in his brain only seemed to multiply. Running his hand down his chest he felt the thick white cum his mother had sprayed all over his chest just seconds ago. He couldn't help himself as he sensually rubbed against the liquid and his new breas - boobs. He groaned in arousal and determination as he tried to pull his hand away. His mother, Margaret, stood in front of him staring,mouth open wide, at her son.
"Heehee, mommy cummy good," James said stupidly. He then brought one hand up to his mouth and begun to suck at the white semen he had collected from his shirt. A soft groan of approval escaped his lips as his blue eyes rolled to the top of his head. James felt so. . . Good? His mother's cum tasted like sugar to the emotionally drained boy.
Margaret could only watch in horror. It was almost as if she had transferred her stupidity to her son. As she stood there slack jawed she felt a familiar rising in her crotch. James really had some great breasts now. Wait! I shouldn't be thinking that Margaret thought with a start. No no no , something is wrong with both of us. We need help fast!
As she watched her son grab more of her cum and bring it to his thickening lips she recognized that his hair seemed to be lengthening and brightening. His normally sandy brown locks were turning a honey blonde if not brighter in some places. As he sucked on the love juice he pulled his index finger from his lips with a loud pop. His lips thickened and deepened in color considerably upon doing so. "GIGGLE," He exclaimed again as he finished the motion. "Does Mommy have more cummy for Jae Jae?"
This pulled Margaret from her stupor. "No Jae-er-James we need help," she responded with sincerity in her voice. James reacted to her voice simply by turning his head slightly as if he was considering her words methodically. Speaking slowly and simply she then said, "we need get help yes." "Help? Like help Mommy cummies?" Her former son responded in confusion a dull look reaching her eyes. "No but close. Mommy help James feel better."
After saying this Margret saw a lightbulb go off in her son's head. Lowering his hands to his side. He then said "what have I done?" He then started to gag a bit as he thought of the cum he had just consumed without a second thought. Margret approached her son and placed a hand on his shoulder.
"It's okay let's get to the lab and stop this."
"Okay, but how is this even possible? Can it even be reversed?"
"I'm not sure James, but hopefully my lab equipment can help us figure something out."
"That would be good, hey wait, where is Sam?"
Both James and Margaret were kicking themselves mentally for momentarily forgetting about their sister/daughter. The two went to look back into the kitchen when they were startled by a very loud grunting noise coming from the other side of the living room. As they turned to look they were both plaster in white goopy liquid! Their hair and torn clothes quickly becoming saturated. As they shook the nasty jizz from their hands and cleared their face they turned to see Sam standing above them.
Her, though it was wrong to call him a her now, changes had continued unnoticed to James and Mergret in the tussle. He was now considerably taller than both of them. His muscle mass had increased significantly while her breasts had decreased to nothing. He stood there with his hands on his 12 inch dick pumping the last remnants of his jizz from the mighty dong. Two large testicles hung from the crotch of his torn female pants.
He had a stupid grin on his face as he looked down on them. "Huhuhu, Jae Jae you look pretty covered in my cum. And you Mae, your boobs are bigger but your p-p is smaller. That's good. I don't want to fuck a girl with a big p-p, growl!'
Margret and James shot a quick glance at each other and their own bodies upon hearing this. Sure enough Sam's cum had caused some drastic changes. James's long completely blonde hair was now framing a face that had no traces of masculine bone structure. He now had wider hips, long fingernails, and smooth sexy skin.
Margaret had also changed drastically. Her breasts had increased in size from a large C cup to a D cup and her penis was now standing erect at 6 inches. However, she could feel a familiar and comforting wetness tingling beneath her small testicles and penis. Her hair was now a deep verdant brown and her matronly ass and hips were curved in all the right places.
Both mother and son looked extreemly slutty in their torn clothing and covered in cum like they were. Margaret looked like a MILFY futa and James looked like an American bimbo. Both of them raised their voices to protest, and were shocked at their elevated pitches. "Oooh, Sammie you got it all over me," Jae Jae drawled sluttily. "You aren't suppose ta cum unless, like, we know it's cumming Sam," an indignat Mae chided. However, the addition of a small giggle at the end of her statement ruined her firmness tone.
Both women covered their mouths at their slutty responses and blushed in shame.
"Grrr you sluts need to listen to me; I am the brains here. You both can get on your knees and clean me," Sam said in his gruff crude tone.
He then held his still semi-hard cock out to his former brother and mother. The two women looked at each other in fear as their loins burst with lust and their brains filled with fog. They really weren't going to clean off Sam's meat sausage were they?
