Heather softly gasped in shock as she suddenly noticed the hand on Matt's shoulder rising higher and higher. His head continued to droop in disappointment and annoyance as his hands clenched and unclenched. Heather watched as Matt's body slowly filled out more of his pajamas as his head inched upward.
"Matty...I think you're growing!" Heather exclaimed without thinking.
Matt frowned and scoffed, visibly becoming irritated as he closed his eyes and grunted, "That's not even funny, mom! I'm trying to tell you how depressed I am about my height and you just make some lame joke!"
As Matt exclaimed his frustrations, Heather noticed his growth rate increased, causing visible tears to begin at the seams of his clothes as his outfit struggled to contain his increasing bulk. Glancing down, she saw a much larger-than-usual bulge beginning between her son's legs, snaking slowly down his pajama pant leg halfway to his knee.
"Sweetie," Heather began, trying to maintain her composure. "I'm not joking with you at all, if you could just calm down for a-"
"Ugh!" Matt suddenly cried, jerking away from her hand and clenching his fists tighter as he shook his head, tears forming in the corners of his closed eyes. "You know I hate it when you tell me to calm down, mom!"
This sudden outburst caused Matt to shoot up in height until his mother actually found herself looking up at him. His shirt and pants burst open and he barely seemed to notice, so severe was his aggravation. Heather realized with a start that his last exclamation had resulted in nearly a foot of growth, making him taller than her. Looking down, she realized his erection had exploded out of his pants, throbbing with gargantuan thickness and length. Heather licked her lips briefly at the sight.
She shook her head. It was clearly his angry outbursts that were causing him to gain mass in leaps and bounds, but she wasn't sure how to calm her son down. Once he became aggravated, he often just fueled his own fury until it burnt out, but at his current rate of growth, she wasn't sure she'd be able to handle him by the time he finally got himself under control. Standing, she stood in front of Matt, putting both hands on his shoulders and lightly shaking him. Looking down, she was once again slightly entranced by the immense size of her son's member. Even in his aggravated state he apparently could not stop his morning wood, as it continued to throb and a large dollop of precum appeared on the head, glistening in the early morning light streaming in from the windows.
"Matt!" Heather said sharply. "That is enough! If you don't get a hold of yourself this instant-"
"Leave!" Matt cried out, and Heather immediately saw his head rise to just below her chin. His clothes were nothing but tatters on his sweating body at this point, the heat rolling off of his skin almost burning to the touch.
Me!" Matt continued, his head now slightly above Heather's even though she was standing and he was still seated. His bed springs groaned at the weight they were being forced to endure. Heather gawked in shock as her hands were rising up, feeling rock solid muscle underneath them. She looked down again in shock as she saw how much closer his massive cock was to her face, the head turning an angry purple color not unlike the shade of her son's face. That dollop of precum looked much larger than it had a moment ago.
"ALONE!" Matt finished screaming, and as Heather Jones opened her mouth to once again plead with her son to control himself, she suddenly found his height and mass had increased to the point that his cock pushed between her lips, stretching them wide over his enormous head. Heather's eyes opened wide as her mouth was suddenly filled with her son's hot throbbing cock, the precum she had been admiring before becoming smeared against the roof of her mouth.
"Mmmmph!" Matt's mother cried around a mouthful of cock, glancing up to see her son's head nearly brushing against the ceiling in his seated state as he drew in great gasping breaths. Heather's eyes were turning red from the amount of cock in her mouth, and she found herself beating against Matt's chest, well above her head, to try and get his attention before he grew anymore.
Just as it seemed she might pass out from lack of air, Matt breathed a little easier and finally opened his eyes, looking down to see what appeared to be a miniature version of his mother trying desperately to suck his gigantic dick.
