You decided that you weren’t done with Luke just yet. Alone with the doll once again, you peered around the corner at Luke, who was still checking out his new big muscles.
You whispered the initial enchantment again, then said, “Make Luke mature in every way until he reaches age 17.” You yourself were 20, so you’d still be significantly older.
You could see the effects set in immediately, and apparently so could Luke. He was quick to realize as his body grew taller quickly, and really knew something was up when he felt sharp pains in the bones of his face as they sharpened with maturity.
You saw him reach up to feel the light black stubble growing on his more rugged face, and checking the dusting of black chest hair that had sprouted. Perhaps most importantly, his muscles grew even more, big enough to shred his clothes, and his dick became the size of a small steel pipe, with chicken-egg-sized balls to match.
As Luke muttered to himself, “How is this possible?”, you ended the spell and contemplated your work. You had to admit, you were impressed, though you wondered if Luke would have naturally become this hunk or if it was due to his already-enhanced masculinity.
You debated what to do next. Should you change Luke more? Should you leave him alone and see what happened? Or should you reveal your role and help him out?
