Mikey hoisted up his spiderman underwear carefully stuffing his engorged cock into it, he softened up to a modest nine inches, but even still it looked like he had stuffed a grapefruit in there. "It feels really weird daddy." Mikey said as he adjusts the massive bulge in his pajamas. "Everything will be ok champ im gonna call the doctor and we'll get this sorted out. how about you sit and watch some tv for a while?" Eric hit the remote and set his son on the couch while he walked back to the kitchen to grab the phone and the GrowMax package. he then went to the computer to find the old email he responded to. In his mind it was to find out more about the company that made it, but deep down he truly wanted to get some more for himself. When he found it and clicked the link, to his shock and frustration he got and Error 404 message. The site he used to get the shake no longer even exists! With a heavy sigh he punched in the number for his son's pediatrician and scheduled for an appointment ASAP. Eric walked back to the kitchen and set the packaging next to his car keys so he wouldn't forget it and walked back into the living room.
"Okay Mikey, I'm gonna take you to the doctor so lets get you rea-" Eric's sentance was cut off as he walked in to see his porn dvd playing on the big screen. "fuck I must've left that in there last night..." Thought Eric nervously as he turned to see his five year old son wielding his massive thirteen inch penis with both hands. He was like a wild beast, intinctually rubbing his swollen member and breathing heavily with the rhythm. "Micheal! What the hell are you-" but before he could finish, his son finished first. Long ropes of sticky white cum flew out of his pulsing cock, there was no way to tell how much exactly, but Eric knew there was a lot. "I'm sorry daddy, i played with the remote and that came on. I don't know what happened after." Mikey nervously looked at his dad and then at his deflating cock. Eric couldn't exactly blame him, he figured there are hormones and rushes the boy never knew before and now he has to find them out instantly. "It's ok Mikey, lets get you ready and go to the Doctor to see what's going on."
Eric put on a tshirt and a pair of shorts for Mikey, seeing that his jeans were too tight and the bulge was obscene. and the two of them made their way to the doctor's office. After a relatively short wait, Doctor Tanaka came out to see them. "Mikey! its been a little while, you've grown so much bigger!" Tanaka said. "You have no idea..." Thought Eric. "Lets get you weighed and we'll see what's going on!" Doctor Tanaka is a natural with her patients, great personality that immediately gets a good response out of the kids. Eric liked that about her, but what he loved about her was her incredible body. Nearly as tall as he is, an incredible smile, with wide curving hips, a firm ass, and bouncing DD breasts. Eric genuinely wonders why she wasn't a model, but I guess being a pediatrician is it's own reward.
After the formalities of being weighed, measured, temp taken, etc., etc.. Doctor Tanaka plopped Mikey on her table and asked "Alright Mikey, what seems to be the problem?" and before he could speak Eric chimed in "Well doc, Mikey got a hold of a suppliment on the counter that was meant for me and it had... side effects". "Well, excess protein in a child's diet can make their body's metabolism off, but it shouldn't be too much to worry about." Replied Tanaka. "Well it wasn't a protein shake, it was this." Eric said as he gave the packaging to Tanaka. "Hmm, strange..." mumbled Tanaka. "There doesn't appear to be an ingredients list anywhere on this box, as a Doctor I would highly recommend not putting anything in you or your son's body that you can't identify." Eric with a defeated tone says "Well theres no way around it, so I guess we should show you, ok Mikey, show the Doctor what happened to you." Mikey nervously looks at Tanaka as she smiles and comforts him. He hops off the table, undoes his shorts, and drops them along with his underwear for the world to see, lifting his shirt up to his chest a loud FLOP can be heard as his cock hits his knees. "My peepee grew really really BIG!"
"Oh my god..." Tanaka said under her breathe as she witnesses the largest penis, no... COCK she has ever seen, and it is jutting out of one of her FIVE year old patients! For a moment all semblances of professionalism was thrown out the window, as her panties under her scrubs grew notably wet. She takes a gulp and kneels down to the boy...
