The whole day, you couldn't keep your eyes off your sister. For the most part she seemed normal, but there were odd moments you noticed. Like how she was wearing a short skirt, she would stretch her legs apart exposing her panties underneath, sitting in poses she would normally never do. And when she'd notice, she would turn red with a bit of embarrassment, and quickly correct her pose.
When she'd have to use the washroom, when she'd get up, a weird smile would grow across her face, and she would be gone for 10 minutes or more. And the odd time, you'd catch her touching herself when she was in the room with you. Either by pinching her nipples, or sticking her fingers into her skirt a bit.
Your mother and Clare return home later that day before supper. The meal was uneventful. When your mother asked you and Heather about your day, you just say it was just a normal boring day. While you were in the kitchen helping your mom with dishes. Heather and Clare were both in the living room, watching a movie together.
Not much was being said between the two, until Heather finally spoke. "Clare, what's it like being a little girl?" Clare looked at Heather confused. "Uh, your a girl, you were my age once. You should remember she replied in a snobby tone. "I'm just curious." Heather replied. "Your being awfully weird Heather." Clare replied.
Heather suddenly seemed to jolt, as she quickly stood up. "I have to go to my room for a minute." She said, as she quickly went upstairs, leaving a confused Clare. Heather walked into her room, closing the door behind her. She looked at her mirror, a look of anger filling her face, as she walked over at it, and stared at her reflection. "What the hell were you thinking of doing to my sister?" Heather snapped at her reflection.
A familiar tingle filled her body, as her eyes suddenly rolled by themselves, seeing the reflection in the mirror. "Relax, baby. I'm only having some fun." She said to herself. Her expression then changed back to anger. "Look, you can do what you want in my body. Like I said, I won't tell anyone, but you have to respect some limits."
A sly smile then grew across her face. "The only reason why you remember anything is because I allow it. I figured it would be more fun this way, and it is. I can wipe your memory any time I want. Your in no position to set limits for me. I'm having a lot of fun inside your body, and I'll go inside who ever I choose. Your mother was fun. Being inside her was a lot of fun. Remember how I went inside of you. I came to your room, as your mother, and while your back was turned, I jumped out of her and into you. It was funny at first when you couldn't remember why you were doing all these things to yourself. And now you know, you have a little homeless guy living inside you."
Heather's face then changed again. "This isn't your body to live in and make your play thing. It's my body." "And a rather sexy body I might add." Heather said in a sexy voice. Heather shook her head, getting very annoyed. "Stop doing that. Stop making me do all these things, just get out of me already. You had your fun."
Suddenly there was a knock on the door. "Heather, it's Clare. Are you alright?" Heather expression then turned sly, as she looked in the mirror. "Alright, you want me out of your body. Consider this wish granted."
She then turned to the door, opening it up, revealing Clare standing there. "I'm just fine Clare. Thank you for asking." Heather then bent over, giving Clare a hug. Clare was shock by her sisters unexplainable behaviour. Before she could react though, she saw something emerge between her and Heather. Before she could react though, it moved towards her, disappearing inside her, her body tingling.
Heather slumped onto the floor, as Clare smiled, looking down at her. "There. You said you wanted me out of your body. You didn't say how though." Clare giggled, as she ran off.
