Switch for the Summer

This is my first submission so feedback is appreciated. English is only a second language for me (Might explain one or three weird sentences). This is the first part in a longer story. Comments and ideas welcome. Please be gentle J

Switch for the summer

Thea had always been small. It was something she had been bullied for in school and that had made her more or less reclusive preferring to hide at home with her books instead of going out with friends. Her mother had eventually accepted this and stopped bothering her about it. In fact, her mother had her hands full with Lisa, Thea's younger sister. Lisa had turned 13 years old but looked much older. While Thea had her mother's small frame Lisa had taken after her late father with quite broad shoulder and a well developed body for her age – the two sisters where the complete opposites. Lisa were both bigger and stronger than her 17 year old sister who where demure and shy instead of outgoing and aggressive as her kid sister. Lisa were also somewhat of a bully but had stayed away from her sister up until now.

Everything had started with Eve pointing out the fact that Thea looked like the baby sister not Lisa. Eve was Lisa's best friend and the two of them hung out everyday after school. Now when school had ended for the summer they stayed at Lisa's house all day soaking in the sun and taking swims in the family pool. That was when Lisa's plan had started to form in her head. In one week their mother was going on a long trip to visit her sick mother. She had told the sisters that she had hired a babysitter to help them out at the house. She didn't trust Lisa and she knew that Thea wouldn't be able to control her sister. The sitter, Ms Herman, would not be able to arrive on the same date as Rose left but she though that her daughters would manage for one night. Lisa figured she only needed one evening to set it all up. It would be a great summer she though smiling.

That afternoon Rose said goodbye to her daughters and left for the airport. She had explained for them that Ms Herman was in charge and that they would obey her. Thea where to be home no later than eleven and Lisa was to be home eight sharp. She also told them that Ms Herman knew all the rules so they couldn't get away with anything.

Lisa smiled broadly when she saw the cab disappear around the corner. She waited until she knew her mother's plane would have taken of before she moved forward with her plan. While Thea were laying the couch reading Lisa sneaked into her room and soon found what she was looking for – the key to her freedom. With the book under her arm she went into the living room to lay down the rules for her sister.

Thea looked up from her book as Lisa entered. "What are you doing with my book?" She demanded and sat up. Lisa just smiled. "I know that you borrowed this book from Mr Lance. If you value it you better listen" Mr Lance was Thea's literature teacher. She borrowed rare books from him, a privilege that she didn't want to loose. "Ok, what do you want?" she said irritated over the fact that her sister seemed to realize its value. "I need you to switch places with me for the summer. You will be me and I will be you" Thea raised her eyebrows. "What do you mean trade places with you? That's silly. Now give me my book" She stood up and approached Lisa. Lisa just smiled and pushed her back. Thea fell backwards and landed in the couch again. "I don't think you have any choice Lisa" She emphasises the name as she turned and went up the stairs to call Eve. "You will not get away with this." Thea felt a sinking feeling in her stomach when she realized her situation.

Eve arrived only a few minutes later and the two friends had a meeting in Lisa's room. How should they proceed with this? While Lisa where hesitant Eve, being a few years older, had loads of ideas.

Thea where in the kitchen when she heard Lisa call on her. Every step felt dreadful as she approached her sister's room. Inside she was met by the inquisition. The two younger girls where sitting on the bed and ordered Thea to stand in the middle of the room. They both got up and circled her like predators. "I told you she would submit to you" Eve said triumphantly. Thea lowered her head in shame. If anything happened to that book Mr Lance would never forgive her. He had told her that it was dear to him and that he trusted her with it. "Let's start with taking of those clothes, sis" Lisa said smiling. "W-h-at?" Thea said. "Just get them of girly" Eve said menacing and took a step closer. With shaking hands she unbuttoned her shorts and pulled them off. She hesitantly pulled of her t-shirt and stood covering her chest as the two younger girls ogled her. "Her tits are so small she could easily pass for a 10 year old" Eve laughed. Beat red of shame Thea felt tears fall down her chin. Her body was something she had been ashamed of all her life. "Oh, she even cries like a baby" the girls both burst into laughter. Lisa sent Eve out of the room and put an arm around her sister's waist. "You can do this the hard way of the easy way. I know you want that book back in one piece and by following my commands these next four weeks until mom comes back you have secured your book. Now go into the bathroom and take a shower."

In the shower Thea cried but resolved that the only option she had was submitting to her sister. As she dried of she had accepted her fate. Back in Lisa's room the two friends where talking about what to do with their new won power. Both girls where delighted to have a 17 year old girl under their command. When Thea again entered the room wrapped in a towel they had put out some clothes on the bed. "Remove the towel, we want to inspect you" Lisa said as she stood up. Beat red Thea lowered the protective garment. "wow look at those nipples" Eve exclaimed. "They are huge. Weird that she has so small boobs and such huge nipples. Looks almost freaky" Mesmerized Eve reached out and touched one. Thea flinched and bumped into Lisa who stood right behind her. Eve started to caress and pinch it and Thea closed her eyes in shame. "Wonder if they get any bigger? Mine grows when I play with them" As the nipples where manipulated she felt something awake inside of her. Something she had been denying for so many years. The shameful tears burned as her body betrayed her. The nipples grew even more to the two younger girl's amazement. After a few minutes they moved on with the inspection. "She's almost bare down there but it all have to go. She needs to look convincing" Eve said. She rummaged though the bag she had brought with her. She gave Thea a pink bottle. She moved closer, only inches from the frightened girls face. "When I come into the bathroom in twenty minutes I want to be as bare as the day you where born. That means no hair below your neck. I'll be inspection you closely so don't cheat" The girls then marched Thea to the master bath and locked her inside. The patch between her legs had always been something she was proud of. It proved to her that she was more mature than the reflection in the mirror showed. Now it was to be gone. The cream was itching but the bottle said that she should rinse after 15 minutes and when she finally showered she could see all her hair disappear down the drain. Everything was spinning out of control. At first she had though that Lisa was only going to push her around a little making her clean her room but with Eve in the picture Thea wasn't so sure anymore. She had seen how Eve had looked at her.

When her tormentors opened the door half an hour later she was bare as newborn baby – Even her arms where bare. They smiled at her and brought her back to Lisa's room to lay down the rules.

The rules had been extensive. She was to move into Lisa's room and start calling herself Lisa. Lisa had already dressed more appropriate for a 17 years old and with the makeup she looked very convincing. They smiled as Thea, now Lisa, saw what they had put out for her. It was one of Lisa's old Sunday dress with both petticoats and ruffles. Lisa had out grown it several years ago and it had been stored in the attic ever since.

When they had dressed her they both fell on the bed laughing. Thea looked at herself in the mirror. She became pale as she was a kid looking back at her. She couldn't be more than 11 years old with the pink satin dress and the pink bows in her hair. Since they had denied her a bra, saying that she was too young for one, her nipples were caressed by the silk with every movement and made two small tents in the fabric, sending electric shocks of arousal to her inexperienced body. She felt herself become damp and with weak knees she sank to the floor crying from the sensory overload she was experiencing. Both the mental impact on seeing herself as the 11 year old she had tried to hide from all these years and from the feeling of arousal now forever linked to the image in front of her. The two girls on the bed stopped and studied her. Eve stood up and approached the sitting girl. She saw the signs of arousal on the distressed girl and smiled a predatory smile. She had secretly coveted the frail teen for over a year and now she was all hers to play with. She let her hand caress the silky material and as she touched the nipples Thea closed her eyes and a quiet moan slipped out. Eve sat down on the floor in front of the poor teen. She let her hands roam free not missing an inch of silk covered skin. Lisa just sat in awe looking at Eve play with her sister. She never could have imagined her sister liking being treated like this. The last shred of conscience concerning the humiliation of her sister evaporated and she joined Eve on the floor.
