Next day Jason and David have a rest day. And day after they had a arm day. Jason's arms grew, as the rest of his muscles did, his quads, shoulders and especially his torso. David and Jason did pull up after push up. They did other arm exercises. After a hour and a half, they were both tired. Jason noticed David had trouble pulling up, his arms couldn't carry his giant body and they gave in, David was dangling for a while, his whole bodyweight supported only by his arms. Jason thought the huge Asian man looked sexy like that. Then David fell down on his feet. He smiled. "I can't do it. Not anymore" he said "let's do it together. I'll push you up, while you pull up. Then you will help me. Let's try again." said Jason with a smile. They tried a couple times and then they were done with workout. On their way to the showers they met Steven.
"Wow, what happened to your arms man? You look huge. Let's weight" After Jason weighed he noticed he weighed 395 lbs now, in addition his body was much bigger, he measured 6 feet 9 inches now. "Heck, man. You are bigger than me! You are getting close to my height." Said Steven "What the fuck is happening? Are you on juice?" David smiled and Jason blushed "no, it's natural growth." David said, "but thanks for compliment man."
Later on Jason felt exhausted and sore all over again, even his muscles in his toes felt sore and tired. David had to help him to shower. They washed each other and Jason loved that. But the pain in his muscles didn't let him forget, and Jason knew the pain won't go away.
On the third morning after their first workout, Jason's body ached even more than he thought it could. David and he had sex the previous night, but it didn't help, Jason still felt the soreness in every part of his body. His body felt too swallowed and full. He stopped to see his legs, only two hairy hills on the bottom of his sight. He told David that he is going to stay in bed for today.
David understood that he fucked up with math and now Jason should weight more than him. He opend magic book and wrote "Jason's height adjust his current weight to make him fill better. Than his weight gains will be 10 pounds per day and 25 if we have training." After writing, David felt little relief. Than he heard a scream from their bedroom.
"Hey David... my body is changin again!" Jason screamed from their bed. David quickly rushed to bedroom with magic book and pen. Jason was standing next to bed, his head was touching the ceiling. He was even taller than David. His muscles looked a bit smaller, but he was able to move and he looked like a jock in every way David likes.
"You are the biggest white on the Earth!" David said and he meant it. David was used to look at Jason with his chin up, but now they were the same height category. Jason looked gorgeous. "And I'll be back". David rushed to the book and add to his last sentence "Noone except me will admit that Jason's growth is unusual"
Two muscle giants, one Asian one white, were in bed together, enjoying each other's bodies and talking about the last day. They didn't talk much, just cuddling in silence. "I guess your ass needed to stretch up a bit before we go to the gym" said David. Jason giggled and David kissed him. Jason turned over and push his butt into David's crotch and he started rubbing it slowly. David couldn't resist it. "I want to see that beautiful butt in action!"
David fucked Jason in a dog position for a good while and then Jason rolled on his back. He wrapped his long muscular legs around David's waist and David began thrusting into his boyfriend again. His balls were swinging against Jason's cheeks, but he could see the pleasure in Jason's eyes. After great sex and dinner they diceded to go to the gym. Jason got up, went to the wardrobe and took out his speedos, he was bigger now but still those tight things looked so hot on him, so Jason decided to wear it. David thought the same and started getting hard. Jason saw it and got hard too. He took of his speedo, kneeled before the huge Asian stud and started giving him a blowjob. Than he continued dressing while David watched him with joy in his eyes.
