Your sister (alternate appearance)

Out of everyone in the house, your sister seemed the more fitting to borrow clothes to cover yourself before your older brother arrived. Borrowing from your mother's wardrobe seemed out of the question, as her style was totally outdated to what modern women wear today. Your sister was fortunately in with the times.

You wasted no time, knowing there was no one in the house at this hour. Unlike you, everyone had plans, people to see, things to do, places to visit. You on the other hand had planned to sleep in and stay home. There was little chance someone was in the house to catch a mysterious girl streaking in the upstairs hallway. Before exiting your room, you peaked and checked if the coast was clear. It was. There was no sign of anyone, not even noises of people moving. You slipped out of your door and into the hallway beyond. Your sister's room was separated from the other four bedrooms on the second level of the house. She liked it that way, since it offered her greater privacy than if she was right next door to one of her brothers' rooms.

Just in case, you peek yourr head over the banister to check for any signs of anyone downstairs. There wasn't even a sign of the television on in the living, a sure sign someone was present on the first floor. You made haste and dashed for the door of your sister's room, slightly aware that in your rush, the long locks of hair tickle your shoulders on the way there. You are actually more aware of nothing dangling between your legs, but that sensation is replaced with the bouncing of your medium-sized breasts on your chest.

The door is ajar, one sign that your sister was not inside. You recall her having taken a couple of summer jobs due to her planning on going to school out of town, moving out of the house to do so. She needed the money to pay for an apartment near the university. The good thing was that she was going to be out of the house for most of the day, coming back home in the evening. You enter her room and immediately find that the morning sun is beaming through the windows. You remember griping about how her room was in the corner of the house that faced more of the other houses in the neighborhood. She also had more windows than in her brothers' rooms. You remember how anyone could peep through those windows and get a free show. You spoke your mind, telling her to keep the blinds closed, especially when she was naked or other states of dress. You guess such wisdom could help you in your current state.

You quickly close the blinds on any window that hasn't been closed already. Once they were all blocked, offering no chances for anyone to see a strange girl perusing through your sister's things, you focus on getting some clothes to cover yourself up. It was a good thing that your sister was the organized one. Her closet and dresser were color-coded and organized by garment type. It shouldn't be hard to pick something out for you to wear. First was the underwear. She had a single drawer that held an assortment of bottoms, from bikinis, to panties, to boy shorts, and thongs, all in varied kinds of fabrics. You steer clear of lacy kinds and go for the comfortable cotton panties, one in a greenish-blue shade. You put them on at once, feeling how it feels flush when you wear it.

Another drawer has bras of different kinds, but you feel you have no time to figure out how to fasten them on your body. You are actually drawn to some of your sister's sports bras, which were usually single-piece garments that needed no fastening. You pick a black sports bra and slip into it. The garment wraps around your torso snugly and it isn't loose or too tight on you. You observe how the fabric supports your breasts, keeping them in place and flopping about. You wonder for a brief moment if you and your sister have similar body types, but you don't dwell on the thought too long. You are still half naked at the moment.

You go into her closet now and can't wrap your head around the more fanciful garments displayed. You choose the easy route, choosing a red T-shirt that isn't loose like what you usually wear on your male body. It fits snug around your torso as well as your arms. For your legs, you put on some grey sweats, the bottom of which ends a couple inches below your knee, exposing your shins.

You suddenly feel the rumble of the garage mechanism opening the door, the vibration going through the floor of the room, which sits right above it. You peek out of the window and find your older brother's car pulling into the driveway. You're at least properly dressed for his arrival, so you quit lingering around any longer in your sister's room, leaving it as you found it and leaving the door ajar upon your exit. You enter your room and close the door behind you. You didn't notice then, but now you discover that your heart's been racing. Was it because you were rushing just now or was it caused by some other matter? Whatever it was, you shake it from your mind and take a seat on your unmade bed.

A couple minutes pass and in that time frame, your mind wonders what kind of reaction your older brother would have once he sees your new body. You also wonder what he could do to help.
