Lying in your mother's underwear drawer was quite boring, nothing happens to interest you. You spent the night in there, you thought about trying to sleep again, but you don't quite know how you even did it the first time.
A noise breaks grabs your attention. Assuming it's just your mother you ignore it but then the drawer opens revealing it to be your sister. "What's her deal!? She seriously took it from my closet!? What's her her problem if she isn't even going to wear it? It's so clearly my size so I'm taking it. Bet it doesn't even fit her." Your sister groaned as she grabbed you from your mother's underwear drawer. You were being taken again! And this time it wasn't an accident!
She quickly shut the drawer and snuck out of the room returning to her own. She placed you on her bed as she removed her current bra that she had slept in. "Waste of a perfectly comfortable bra to just sit in a drawer." She continued mumbling to herself as she grabbed your cups.
She lined you up on her chest as she ajusted your straps, with your cups centered on her nipples she facened you. Now bearing the weight of her chest you couldn't help enjoying this. It sure beat lying in your mother's underwear drawer, that's for sure.
she threw a shirt on over you. Picking up her bookbag she left her room, her breasts bouncing slightly as she went down the stairs and out the front door heading to school. She got into her car and drove to school, where you sat on her chest as she went through her day.
After school she got back into her her car and headed home. On the way she suddenly exclaimed, "You know what, it might be petty, but I'm doing it." She changed her course and headed down a road not towards your home.
She pulled into the parking lot of a mall. Getting out of her car she jogged inside, her chest bouncing you around as she ran. Inside she made her way to the mall's Victoria Secret, inside she scanned the racks until she found what she was looking for.
She picked up a green bra that looked just like you!
She quickly bought it and returned to her car driving home.
Once home she ran up to your mother's room and placed the other bra into your mother's underwear drawer! "If I want this bra I'm gonna have it! You can just have that one! What difference does it make when you don't even wear it!" She laughed to herself.
She returned to her own room. She leapt onto her bed, her chest crushing down on you as she landed on the bed. She pulled out her laptop as she browsed YouTube and other websites.
You wondered what would happen now? You were only supposed to transform for seven days, so what would happen now? Your mother has no idea you've been swapped out with a fake, so once the seven days are up what will happen to you?
Assuming your mother takes the other bra back to be transformed back into me what then? Surely they will realize that isn't me then right? But after that will they be able to find me?
Then the thought of being trapped in this form hit you. If you went too far past the time limit maybe you won't be able to turn back!
Your thoughts were interupted by the sensation of your sister shifting her position on top of you. Your bra brain unable to focus on anything besides this sensation.
After an hour or so your mother returned from work. Going up to her room she opened her underwear drawer and pulled out the green bra inside talking to it. "Jeff I hope you are learning a lesson about transformations!"
The bra didn't respond. "Silent treatment, huh? Just shows you understand how bad you've been!" She returned the green bra to her underwear drawer. She had completely been fooled by the imposter bra!
Your sister got up eventually entering into the bathroom. Turning on the shower she began stripping off her clothes. First her shirt and skirt, standing beside the mirror in just her undergarments.
Jeff looked at the green bra in the reflextion, his own reflection. She pulled him off her chest placing him into the pile of clothing she had removed. He watched as her naked figure disappeared behind the shower curtain. He listened as he heard the sound of water bouncing off her body. After a bit the water turned off and she stepped out with a towel wrapped around her.
She picked up Jeff and the other articles of clothing, carrying them to a laundry basket where she deposited them. She walked to her bed and threw on her sleepwear.
"Hm.." she muttered as she looked over at the laundry basket. She walked over and pulled Jeff out. Was she going to wear him again?
"Just in case mom figures out the bra she has is a fake and comes looking for the real deal I better hide this."
She carried him over to her bed placing Jeff inside her pillow underneath it. No one would ever check there.
Later that night when she climbed into bed he could feel the weight of her head pushing the pillow onto him. He wondered what would happen tomorrow as he listened to the vibrations of her breathing.
The next two days passed without any events. Your sister woke up and left for school, your mother left for works, all while no one else knew where you were. At night your sister slept on top of you.
The next day is the weekend, tomorrow is the seventh day of your transformation and the day you were supposed to turn back. You are pulled out from under the pillow by your sisters hand, holding you close to her chest she carries you over to the laundry basket stuffing you into the center of it hiding you among the other articles.
The weekend is when your sister did her wash, so that's why she had placed you into the basket. Carrying it downstairs she threw you into the washing machine, making sure you were in the back and couldn't be seen from the outside just in case. Your sister was quite serious about not letting your mother take away her most comfortable bra.
Once the wash cycle ended you were thrown into the drier. Becoming warm and steamy. Your sister pulled you out along with the rest, carrying the pile up to her room. She threw us all onto her bed, pulling me out from the rest.
She removed her current bra putting me on instead. She let out a moan of pleasure as my hot cups touched her breast. The warm feeling of being held by me was pleasuring for both of us.
Throwing her shirt back on she put the rest of her fresh clothing away. Today your sister had plans, she was going to:
