Chastity's younger 12-year-old brother Bradley was standing in the archway of her room holding her stone in his hand. "Give me that back!" Bradley dodged out of the way. "I wish I knew what you were so angry about sis."suddenly his eyes shot open with knowledge about the stone.
not wasting any time seeing Chastity rebound to go and strike her brother "I wish I was the most muscular kid in school!" His clothes ripped off his body as his muscles rapidly inflated. Looking like a young powerlifter. His ripped up tatters reforming around his genitals becoming a snug Speedo. Bradley lifted his powerful arms and pushed his sister onto her bed. Chassis couldn't hear him as he muttered under his breath flexing in her mirror. Suddenly the mascular boy started rapidly aging his face becoming angular and mature his muscular body becoming taller and even bigger through puberty his penis spraying erect in his snug Speedo straining the semen drenched fabric as it elongated becoming thicker and vanier thick pubes developed around the base sprouting up to a cute happy trail all around his belly button leading up to a proud ticket and his arms and legs became harrier as proud bushes of hair emanated from his armpits. The powerful man flexing before his sister started to look strange as his tightly cropped haircut began growing and elongating down past his ears reaching his firm muscular ass his lips pumping in his eyelashes thickening his eyebrows shaped up and peaceful makeup appeared on her still semi-masculine face and a bikini top appeared around his muscular chest. suddenly all of his chest hairs became light blonde and began rapidly receding into his flesh as his skin became smooth and supple his nipples spraying hard as his chest began inflating becoming perky D cups joist mounted onto hard rigid pecs. Where her brother once did now stood a tall beautiful hairy shemale. Brad moaned in a deep voice as he rubbed his stiff member and perky nipples playing with his large breasts still standing erect in her Speedo "I wish Chastity would come suck this" zoning out and I'm thinking chasty got up from her bed and scrambled over to her muscular Brothers thick meaty hairy thighs and relieved his hard cock from his strained semen drenched Speedo and began slurping away at his meaty 8-in member.
