Luke jumped in surprise, trying to repress his ejaculation but to no avail. His first shot splattered on the bed as he let out an audible gasp. He looked around for his shirt to cover his privates but he had tossed it out of reach; another generous surge oozed from his small throbbing cock, and Luke came all over himself.
"Don't come in!" he shouted with his cracking 12-year-old voice.
There was a moment of silence, until he heard his mother through the door: "well, okay Luke, but breakfast's ready". He heard her footsteps walk away, and let out a sigh of relief.
Luke rummaged through his closet, and was surprised to see all his clothes were fit for his age and size. Was he dreaming? What world did he awake to? Did using the condom alter reality or was he losing his mind? Had he been 12 all along and the rest was a product of his imagination?
He grabbed some clothes and rushed to the bathroom to clean himself. A boyish face over a scrawny body looked back at him in the mirror. His penis was soft again and looked so small in comparison to what what his 18 year old body used to have. He shook his head and hopped into the shower.
Luke got dressed and came down the stairs, holding his breath as he entered the kitchen. His mother looked up, and for a second that seemed like an eternity he wondered what kind of reaction he would get.
"Good morning my big boy. How's Christmas going for you so far? I know school hasn't always been fun lately, what with your condition and all."
Luke raised an eyebrow. "My... condition?" His heart raced.
"You know, honey... It's hard enough being a teenager, let alone going through puberty later than your peers. But don't worry, I'm sure the friends you'll make in college next year will be more mature than the seniors in high school. You'll fit in just right."
Luke nodded silently and sat at the table to have breakfast. Apparently, he was still living the life of a 18 year old, even though he his body was 12. The day promised to be interesting.
