Ryan felt strange all through first period but he couldn't quite put his finger on what it was. It was a queasy sensation in the pit of his stomach. His clothes also felt unusually snug and comfortable. Maybe his mom had used a new detergent he thought to himself.
His next period was gym class which happened to be one of his favorite classes. It didn't require him to think very hard and he could check out the hotties in their gym shorts. Little did he know he was well on the way to becoming one of those hotties.
He prided himself on being the first one ready and dressed so he hurried to the locker room before anyone else arrived. It wasn't until he removed his shirt that he realized something really wasn't right. A lacy white bra had replaced his football pads and he had slimmed down considerably. As he went to touch the bra to confirm it was real his A cup breasts jumped a bra size to large B's leaving him clutching a handful of bosom. He massaged his new breasts in wonder, and then realized a sensation was missing. Looking down he could see that his pants had crawled up his knees and were flared and pleated like a cheerleader skirt. The pants were also so tight that a bulge would be obvious if there was one. Pulling down his pants he saw that his jock strap had transformed into a white thong. Pulling that out he could see all that remained of his once proud member wasn't much more than a button and his scrotum was empty and pink.
Shocked he ran to the nearest mirror. Looking at his reflection he saw a muscular girl with blonde streaks in her shoulder length brown hair. The girl looked enough like him that he was convinced it wasn't a trick. He was amazed as the reflection got even girlier. Pulling down the thong he watched as the last of his manhood left him.
More students from his class started to show while he was in his underwear with his hand down his panties.
