Gabrielle had just entered to see her fiance dressed in her sister's nightdress. “John! Can you explain me why you are wearing a skirt?” she said seriously. “Ehm I... I can explaine... sure” he hesitated “I... I want just to see how it feels to wear a female dress... it was only innocent curiosity”. Then he tried to take off the dress, but his fiancee immediately interrupted him “don't evene try to think that you can take off that dress!”. He was confused, but he responded to Gabrielle's order. “Mary, come here now!” she called her sister. John paled “what are you...” but before he could say the last world, a laugh freezed him. Mary behind him had just seen her brother in law, a man so proud to be a man, dressed up in her pink nightdress. “Mary” Gabrielle ordered “look for a dress thou wore when thou was younger” the 16 years old girl went upstair again looking for that dress. Then Gabrielle pointed a chair “and you John, just seat down there!”. He made as she ordered and then whispered “please honey, forgive me... I didn't want to make you angry” but she didn't anwer to him and went to the kitchen. When she came back she had a damp cloth in her hand. In the same time had reached them with a green drees she was used to wear when she was 12 “This is the oldest I could find. If thou need I have several garment I wore when I was that age, but nothing older” she said to her sister that answered with a smile “don't worry, this will be perfect: losing almost ten years will be a sufficient punishment”. “So thou won't marry him? Thou will stay with me?” “thou can swear it, sis!” Mary hugged her older sister and, with a happy smile she went back to her room, leaving them alone.
John didn't understand what they were talking about, but he had sensed that something bad was going to happen. “You can take off that dress now, sweatheart” Gabrielle said. He smiled and took off that dress, but then she ordered “take off also your male clothing. Then I'll give them to my father. They'll fit him”. John tried to protest “you are joking, I can't believe you want to see me naked before of our wedding” but seing that she wasn't joking, he made as she ordered. Then Gabrielle gave him that wet clothing and said “now touch your penis for a while with this”. This was weird but he didn't protest more and responded to her order. “Now you can wear this dress” she said giving him her sister old dress. He gazed at it and seriously said “this is too small, it won't fit me” but she calmly anwered “You'll see that it fit perfectly you”. I did. Then he eard Gabrielle saying “now be a good girl and have a nap before our parents came home”. Confused, he answered “what?” but he winced earing of his voice was so high pitched. He looked at the mirror: the reflection was that of a cute blonde 12 years old girl, slim and short, with two small breasts (we would say, today, less then an A cup) in a green dress. It could not be possible! He raised the skirt to be sure that this was just a joke, but seeing a vagina instead of his penis he began crying in a girlish manner. “What have you done to me?! Change me back!” he, or better she, screamed. But Gabrielle seriously and calmly aswered “thou have chose thy own transformation. This is permanent. Don't worry, nobody exept for I, thou and Mary, remember thou as John. Thou are simply Joan, my little sister. Thou can use the 'thou' with me, from now on, since we are sisters now”. Joan sadly said “but I never told I want to be a girl... I was happy as a man...” Gabrielle caressed her new sister cheek and said “You have time to learn how to be happy also as a woman, growing up again: you had chose it wearing that skirt”. “But it was only curiosity!” Joan protested. Gabrielle sighed and solemnly answered “curiosity has its price!”
