Jason and David’s relationship progressed quickly. Having grown up together, they had a level of comfort and ease with each other that it takes many couples years to achieve. Jason was back in school and David,, who had no interest in grad school, continued to work at his job. They would workout together 5-6 days a week at the gym. David had wanted to change gyms, but Jason convinced him that he couldn’t let the Lee Brothers run them out of the best gym in town. And of course Jason had his reasons.
After the gym, they would usually go back to David’s house. It was closer to the gym and more comfortable than Jason’s apartment. As time went on, Jason would only stop by his apartment to check the mail or grab clothes.
During the first month after he wrote David’s growth in the book, Jason was in agony. He wanted to see results immediately, but he knew his plan was solid. About two weeks in, he noticed that David was filling out his clothes better. By the end of the month, David mentioned that his more tailored clothes were getting too snug and he needed to go shopping. David was over the moon at gaining 15 pounds of muscle in just 4 weeks, he had never had such results at the gym though it was not unheard of for East Asian men to gain muscle that quickly.
At the beginning of the 6th week, David and Jason were spending a lazy Sunday at David’s house. They were in the kitchen making sandwiches for lunch when David gave Jason an odd look.
“Hey baby, how tall are you?” David asked.
“6’2”, why?
“I think I’m taller than you,” David said. “Are you sure your not just stretching 6’1” and half to 6’2”?”
“Um. You’re Korean David, of course you are taller and more muscular and have a bigger dick than me. This should not be news.” Jason replied with a smirk, “and no, I am 6 feet 2 inches on the dot.”
David walked over to Jason, it was clear that he was a little taller than Jason as they were standing barefoot in the kitchen and facing each other. “I have been 6’2” since I was 17,” David said, “I’ve always wanted to be taller, but I know I am just 6’2”.”
“Well, there is one way to prove I’m not lying.” Jason replied, “where is your measuring tape?”
Jason stood against the kitchen door frame and David marked his height. The tape confirmed he was 6’2”. “Now it’s your turn,” Jason said. David’s mark was higher than Jason’s and, after measuring twice, was at 6’3 1/4”.
“I’m almost 25. I thought I was done growing, not that I’m complaining.” David said, “but it is odd. Maybe I should see a doctor.” Though he was mildly concerned, David was also very turned on by the fact he was growing and his now 12.5 inch dick was at full staff. Jason was on his knees in a second. Pulling down David’s shorts, his big dick was so hard that it popped out and slapped Jason’s chin. Jason was happy to worship his big man’s cock and noticed how much fuller David’s legs muscle were as he enthusiastically worked on David’s dick.
“I think you are bigger down there too” Jason said as he was wiping off and licking up the huge amount of cum that had spilled from his mouth onto his chest. “Hand me the tape.” Jason said as he stroked David’s cock back to a full erection. He took the tape and exclaimed “it’s a little over 12 and a half inches!”
David excitement at growing again showed as his dick started twitching. The over 6’3” nearly 230 lbs stud grabbed Jason under the arms easily pulling him to his feet, “bedroom now,” he said. Jason liked the assertiveness and was equally turned on by David’s growth. He quickly pulled off his shorts and climbed on the bed on all fours, offering his tight ass to David. The extra length and girth hit Jason’s spots perfectly and he came after a couple of minutes of hard pounding. David, being so turned on by his new size, did not last much longer.
As they laid cuddling in bed in a state of euphoria, David grabbed his phone and started to scroll. “So according to the Mayo Clinic, it’s not uncommon for EastAsian men to continue throughout their 20s and they may grow between 1 and 2 inches between 20 and 29. However; rare cases of exceptional growth have been documented, including a 26 year old Japanese male growing 4 inches in one year,” David read aloud. “Can you imagine me being 6’6”? Wouldn’t that be something?” David asked. “I know I should not get my hopes up, but that would be awesome.”
Jason smiled knowing that David was going to be much taller than 6’6” and was glad he was so excited about growing. “Mister, I found you sexy at 6’2” and will find you sexy at any size.”
The next week, Jason was at David’s waiting to hit the gym and David was late getting home. “Sorry, should have called, but I wanted to tell you in person;” David said, “I had stop at footlocker on my way. I’ve been cramming my feet in these size 13s and they have been uncomfortable for weeks.” He continued, “I guess everything on me is getting bigger, I bought 14s but only one pair. If I grow just a little more, I’ll be in 15s soon.”
David’s growth did continue.
David and Jason kept up their workout schedule. David had always been stronger than Jason, but watching him add plates and use heavier dumbbells aroused Jason. All the weight David was gaining was pure muscle per Jason’s edits to the book. David was pretty lean at the beginning and his muscles were becoming fuller and more defined with each passing day. Jason would often try hard to think about other things to keep from getting an erection while working out.
They would always try to avoid the Lee brothers at the gym, but like all bullies they sought out their victims. The typical taunt from the brothers would go something like “aw little davie and his wittle friend are trying to build muscles?” Followed by a flex and reminder that was what “a real man” looks like. Jason also noticed that when he happened to make eye contact with either brother, they would wink and give him their cocky smug smile. Jason couldn’t wait until David showed them “a real man.”
At the end of the second month, David came home with size 15 sneakers. “Hey baby,” he called to Jason, “I think it’s time to measure again. I busted out of those little size 14s.”
Backing up to the door frame, it was clear David had exceeded his old mark. Upon hearing he was 6’4”, David’s dick started to stir. He went to the bathroom scale to find he was now 240 lbs of solid muscle. His dick was now completely hard and obscenely bouncing in his shorts. Standing in their bedroom, he told Jason to get the tape measure. “I’ll let you take the last measurement,” he said with a smile.
Jason approached his big man. Standing there in his underwear, David’s huge hard dick and ripped muscular body were a wet dream come true. “Don’t be shy, take them off” David teased looking down at his underwear. Jason complied, releasing David’s cock but struggling to get the underwear over his thick thighs. Jason grabbed David’s dick, it felt heavy in his hand and his fingers barely encircled half of its girth. He laid the tape along the top, “13 inches baby,” he whispered.
David picked up his little man. Jason wrapped his legs around David’s waist as they kissed and David put his fingers in Jason’s tight muscle ass. Sex on measurement day was always going to be fun.
During the third month of his growth, David’s confidence and assertiveness increased in proportion to his body. Both he and Jason were so turned on by his gains that they were fucking like rabbits. Jason would often interrupt David getting dressed in the morning to suck his growing dick. Every evening without failure, they would come home from the gym, down a protein shake and hit the shower together. The sex always started in the shower, but rarely ended there. Jason became more and more turned on by David as he was exhibiting his strength more during sex or gently teasing him about being smaller.
Around the end of the third week of that month, David had to buy size 16s. He wouldn’t let Jason measure him and he wouldn’t weigh himself until the end of the month. He wanted wait and start taking his measurements the last day of each month to set a schedule, something to look forward to.
In the week before the measurement, David and Jason realized working out together didn’t make sense. David had become so much stronger than Jason, that they were constantly racking and re-racking weights and wasting time. It also hurt Jason to admit that he couldn’t be an effective spotter for David as there was no way he could handle the weights David lifted. David started working out with a Chinese guy named Ming. Ming was about 6’7” looked to weigh iabout 250 lbs. He was a nice and always treated Jason with respect and kindness.
This development worried Jason, though. Was he going to be enough for David as he grew bigger? As they were getting in bed that night, Jason couldn’t help himself, and despite knowing how it sounded, he blurted out “are you going to leave for some Asian stud? You’re getting so big and I’m afraid I’m not going to be enough for you.,” David sat up in the bed and with his big arm he pulled Jason next to him. “Baby, there is something I’ve been meaning to talk to you about,” David said, “in case it’s not obvious, I love you - you fool. Those big Asians don’t and couldn’t make happy the way you do.” Then with a smirk, David said, “Besides, I don’t think there is another ass that could squeeze my big cock like yours can.” Relieved, Jason said “I love you too, now lay back and let me keep the memory of my tight ass fresh for you.” Jason
Finally, the last day of the third month arrived. David stood 6’5”, weighed in at 255 pounds and had a 13.5 inch dick.
Learning the stats, David and Jason’s dicks were rock hard. David sat on the sofa, his huge cock rising straight up. He leaned back and told Jason to “come sit on daddy’s lap.” Jason lubed up his pink hole and obliged. David let Jason ride him for a few minutes before standing up with Jason still on his, he carried him to the bed and proceeded to fuck Jason so hard that he felt he was in a constant state of orgasm for the 15 minutes it took David to blow his massive load.
Afterwards, laying on the bed next to each other dazed and panting, David said, “you know I said I didn’t want to get my hopes up, but I’m so close to being average height I can’t help it. If I’m being honest, I hope I don’t stop at 6’6”. I would love to be bigger than those ass hole Lee brothers.”
Jason just smiled.
