His heart began to beat faster and his breath quickened as his balls descended and began to pump testosterone threw his young body at such an early age. His child sized uncircumcised penis began to harden as hairs began to push out at its base and spread outward. As hairs pushed out under his arms and around his ankles his body went threw a growth spurt at 9. His shoulders had widened some and his muscles were already beginning to grow. His penis was still hard, although now 5 inches long.
Joel grasped the bed as his body passed 10 with a maturity of 15 or 16 due to the early onset of puberty. He was already 5'10" in height with hair covered legs and feet. Above his 7 inch dick the brown hairs moved in a line across his navel and up his tight abs and to the middle of his peaked pecs.
"Fuck ya!" Joel moaned in a deep voice as his large balls began to churn without his 10 inch penis being touched. As facial hair grew into his now 16 year old body his cock began to shoot as the changes in his body ceased and Joel went out of consciousness.
