As Jon slept subtle changes took place, Zoe was only a year and a half younger so the age reduction was not too obvious, they even shared hair and eye colour so that also remained the same, but the brown hair on his scalp began to grow, longer and longer, his skin shed all hair below the eyes and took on a paler complexion even as the skin became softer, more sensitive and completely blemish free. Due to the already existing DNA match the changes were quicker, as Jon turned over in his sleep the slight puffiness on his chest was squashed together, forming the beginnings of cleavage, even as his nipples became bigger and milk ducts formed behind them, even his areolas grew as his nipples looked more like those of a young girl in the early stages of puberty.
The dark hair of his scalp took on a body and sheen as it became silky soft and cascaded across the pillow in a dark mane, thick, slightly wavy and the loveliest hair you could imagine, any girl would kill for such luscious locks!
Jon's lips became plumper, altering their contours slightly to become the kissable lips of a sexy young woman, fat faded away as his build became that of a young woman that worked out but wasn't a professional athlete. as the changes began to affect his skeleton Jon whimpered , in a voice already higher and softer, longer lashes framed lovely doe like eyes that were a rich, gorgeous hazel colour. the puffiness behind his larger, girlish nipples grew, soon reaching Zoe's modest B - cup, then Jon began to shrink from his 5'11" to Zoe's 5'6".
Jon began to dream, in the dream he and Zoe were going shopping, for some reason they were both wearing dresses, his a lovely silk sundress in purple and white, while his sister wore a darker, lacier version, her dramatic gothic make - up in contrast to Jon's lighter look. In the dream the pair of them were holding hands, laughing and having a wonderful time, Jon felt filled with affection for his sister and tears fell down his cheeks as he remembered happier times when he and Zoe played together as little kids, for some reason Jon did not realise that both he and Zoe were female in this dream, being a girl felt natural, even desirable. Being Zoe's twin was the best thing, she loved being a girl and she and Zoe were the very best of friends, life was good!
And then Jon awoke.
The odd weight shifting on his chest was the first clue, the second was the feeling of his very long hair tickling his hairless shoulders, the third was the odd ache in his joints , especially around the hips. By the time he realised his Pyjamas felt a few sizes too big Jon had begun to fear that his dream was prophetic. Really though, wouldn't that just be the best? To be that close with his beloved sister would be worth giving up his manhood for, with a determined look in his pretty eyes Jon got up, keen to see what he looked like.
