Kid to Beast- A TS4 Story (NSFW) 10 (Patreon)

Arian awoke the next day with a raging hard on and measured his throbbing dick at  8' long. This sent him over the edge and he jacked off profusely. He showered his immaculate body down, his pecs looking thicker and rounded than yesterday, and got ready for another day in the gym. Before that, though he had his usual routine check-up at the doctor.

After his huge breakfast which had Mrs Fry cooking 6 eggs, 4 sausages as well as 2 rashes of bacon and 4 slices of toast as well as the usual baked beans Arian washed it down with a pint of protein shake. He burped loudly. His mother turned from the sink to give him “that look” Arian quickly covered his mouth in disgust. “Pardon” he squeaked his voice cracking as he did! Has his voice broken again? He rushed to the garage his hair slightly brushing the top of the door frame, and muttered to himself. His voice was significantly deeper than it was the previous day. Joy set in as he fist bumped upwards! He really was turning into a man! A muscular man.

Suddenly he looked towards the door. Had his hair just touched the top? No, it couldn’t have.. surely. He normally measured his height and weight once a week but he suddenly needed to know! He stood against the chart and marked with his trusted marker and took a step backwards. The mark is etched across the 6”8 marker. Mouth wide open Arian stood there motionless for a good minute comprehending what he had seen. He’d grown 3 inches in 24 hours! That was impossible! He rushed over to the scales, the needle spun and landed on 203Ibs a gain of 11 pounds in one day! This was his biggest growth spurt yet! Ecstasy set in!  Arian smirked and raised his arms. He closed them into a tremendous double biceps pose. His biceps formed ripped, hard peaks of pure teenage muscle. Thick veins snaked down his meaty forearms and over the peaks of his biceps. His giant triceps filled out his upper arm to amazing proportions. He flexed his arms over and over, pumping up his growing 20 inch biceps! It was really happening! His wish of being the biggest bodybuilder might not be that absurd after all!

On his way out Arian, boosted by his growing muscles and feeling very cocky posed in front of his shocked parents. Showing off his thick chunky biceps and startling bulging pecs. They were left without words, what was happening to their son!
