Sally had known Mark since childhood and through their teens, she knew well how horny he had been and frequently had 'erotic dreams'. Carefully she placed the medallion around his neck, he snored a little but seemed to calm again. Sally searched the bag hidden under the bed and found an old pair of jeans he used to wear, these should have been sent to the charity shop long ago but it seemed they had been forgotten. She let Mark's fingers touch the fabric and the change began.
Sally stared wide-eyed as his traces of facial hair faded away. She shivered with glee as he began to shrink slowly, with most of his body hair fading away as he did. She leaned closer to watch his impressive muscles melt away as his limbs became that of a scrawny teen.
Sally watched on as that impressive six-pack became flat and almost as womanly as hers (late developer maybe?). She watched as his mature features became that of a teenager, his jawline less manly.
Next came the best part, his thick cock began to shrink and become thinner, far less impressive at just four and a half inches or so, and the pubic hair around it mostly receeded. Still legal at least.
The transformation was complete. Sally carefully removed the medallion from around his neck and admired the results of her work, this was amazing, he would have no clue what had changed him.
Sally watched as Mark moaned in his sleep, his cock was stiffening and he gripped the sheets. Sally bit her lip and felt the wetness between her legs in excitement, was he going to have a wet dream?
She watched as his breathing quickened, a small moan passed between his lips. What should she do? When he wakes up, should she act unaware of the change and pretend to be his Mom, Aunt or older sister? Perhaps act shocked at his change and 'help' him through it. The most embarrasing thing she could do would be to become his Mom with the medallion, but did she want to use it on herself?
Time was running out.....she had to decide now.....
