Lily’s big brother had never really taken much interest in her. He always seemed so reclusive and distant,  so really there had never been a chance for her to get to know him very well. That was until one day she caught him in her room, trying on her clothes. Well not physically trying them on really, just, holding them in front of him while staring longingly into the mirror.  At first she was surprised, and blurted out what she thought she was supposed to say.

	“What the fuck are you doing? Get the fuck out of my room!” She yelled in typical teenage fashion. Her brother quickly absconded, but for a moment she saw the fear and the sadness in his eyes and for some reason she felt kinda bad. “Wait.” She grabbed his arm as it was closing the door. “Wait.” She said again, locking eyes with him. “Sorry I… overreacted. You weren’t doing anything wrong… Do you want to talk about it?” She said apologetically, pulling on his arm, beckoning him to come back. After years, a decade of coldness, could this be the chance for her to finally feel like she wasn’t an only child?

	Like a wounded deer in the forest being led with the scent of food she pulled him back in and sat him down, closing the door behind to make sure they weren't disturbed and locking it for good measure. “Okay.” She said sitting across from him. “Talk.” He looked around the room, still a panicked look in his eye. She realized it sounded like she was interrogating him, so she filled the silence. “It wouldn’t have fit, you’re a few sizes bigger, maybe some of moms clothes...” This made him put his hands between his thighs and drop his head. So he probably had tried that then. “Well how did they feel?”

	“… Like they fit me wrong.” He said in a small sorrowful voice. Fair, she thought, mom was a big woman they probably felt awkward. 

	“What if they could?” She asked. “What if there was a way to change you, a magic button you could press that would make them fit. Would you press it?” 

	An eager nodding came from her “brother” who she was rapidly growing to suspect wasn’t that anymore made her smile. “What do you know about HRT?” She said smile turning into a grin. Her “brother” shook his head. She pressed into him, excitement making her place her hands on his slender thighs and get close to his face. He flushed.

	“It’ll make you like mom, like me. Its like, second puberty.” Lily said with a wide smile.  “I know a way to get you on them ASAP. We can worry about doctors later. You’d like that wouldn’t you?” He nodded, a mix of fear and awe at his little sister evident in his eyes. “Good.” She pat his hair and brought him in for a hug, squishing him against her chest. She couldn’t see, but he flushed hot red, hands clenched against his thighs in his lap while his sister gently pet him.

	Lily had a thought. “Do you know what you want to be called? Once you’re a girl I mean. I could get a head start on calling you by your new name now!” She released the hug and squeezed his hand.

	There was a long pause, Lily patiently waited, and then, “Rose.” Said Rose, trying to hide her face and voice as if somehow if she just folded up enough she could disappear. 

	“Rose.” Lily said back with stars in her eyes. “Oh you do care about me don’t you? You wanted to match!”

	Rose was currently on the floor with an expression somewhere between shock and ecstatic. Lily leaned over her and gave her a big kiss on the cheek, which elicited a squeal. Rose had never imagined this could happen. It was like a dream. Sheepishly,  still on the floor, she beckoned her arms out for a hug. Lily lay across from her and cuddled up, intertwining Rose’s legs and arms together with hers and smiled as she said  “Sister!” excitedly.

	They both giggled on the floor. She cupped her sisters face in the palm of her hand. Looking at it as if for the first time. Rose was so squeamish, so not used to touch and love, Lily thought it was almost a little sad. “Tomorrow lets get you some new clothes. You can drive me and I’ll pick stuff out for you, it’ll be ok they’ll just think its for me.” Lily smiled reassuringly. Rose nodded, happy to let her sister lead her.

	The mall wasn’t too crowded. Lily brought them to a couple of department stores she knew had cheap clothes, even hand me downs. “You’re gonna want essentials.” She said as she picked out some underwear and a single sports bra. “You can grow into it.” She encouraged when Rose clutched at her still flat chest. “They help give you the shape, and if you outgrow them we can just come back.” Lily’s smile was radiant so Rose just nodded and let her put it in the basket.

	She picked out some pants, a skirt, a few tank tops a few t shirts, some new shoes, some socks, even a pair of thigh highs. Rose was tugged along for the ride in a daze. Only breaking it when she was dragging her to the changing room. 

	“Hey.” Lily turned around when she felt a tug of resistance. “It’s ok, you’re just escorting your sister around right? No one will think twice.” Rose nodded, not able to refuse her sister who had been so nice to her.

	Predictably Rose was too nervous to take off her clothes herself, but Lily was not shy. Forcing the t-shirt she wore over her head. Unbuttoning her jeans and taking off her shoes.  She smiled wryly as her fingers grasped around the underwear.  “I haven’t seen this since we were kids. It’s a little bigger than I remember.” She teased. “Oh don’t you worry I’ve had sex ed. Its perfectly natural to be like this when a pretty girl is undressing you.”  She added after a pause. “Even if that girl is your sister.” Lily made note of the twitch it did when she said the word ‘sister’. 

	She opened the pack of underwear they had just bought and clipped off all the tags on the bra. They fit Rose’s slender body well, the little support cups in the bra adding just a hint of A-cups to her body. The underwear however barely contained the excited Rose. Lily thought about touching it, but held herself back. She wasn’t quite sure her sister could handle it if she did it right here right now. The skirt was so small you could see the bulge if you got any angle below it. Lily licked her lips unconsciously. 

	When they had tried on all the clothes, Rose moved to take the underwear off, but Lily stopped her. “Leave it on.” she said. “You can wear it under your clothes.” Another twitch, this one sending shivers up Rose’s body. Lily put the clothes on while Rose stood there frozen, only moving for her touch. “Gosh it’s like dressing up a doll.” She smiled up at Rose while she fit her feet through the pant legs of the jeans she had brought.  “Or maybe just a child who can’t dress themselves hmm? You know I’ve already gone through puberty. You restarting… well that would make you the younger now wouldn’t it?” Lily pulled up the pants, making sure to brush the outline in Roses underwear with her hand as she buttoned them up. “There, that wasn’t so bad now was it dear sister.” Rose looked ready to fold up and disappear right there. The bra drew the faintest outline of buds on the loose t-shirt. Lily led the stupefied Rose back through the mall like a parent leading a child.

	“There’s one more thing. I have a friend coming to drop something off.” Lily smiled and led Rose to the food court. She approached her friend, who was waiting at a table with a half eaten sandwich and a brown paper bag. 

	“So this is the lucky new girl.” Lily’s friend said. “Pleasure to meet you, I’m Lenore.” Lenore held out a hand. Her husky voice sounded pleasant and smooth. Rose stuttered an “N-nice t-to m-meet you ma’am.” While shaking her hand very rigidly and business like. Lenore just chuckled.

	“First month is free, I can also recommend some doctors for a prescription.” Lenore handed over note full of names and numbers. “Our chemist friend is happy to accommodate for however long she needs and to fill any gaps in pharmacy availability.” She slid the brown paper bag over, which Lily took. “You know how to do injections?” Lenore asked. 

	Lily nodded. “I watched a video, I’ll teach Rose no worries.” 

	Lenore turned back to Rose. “I look forward to seeing how you change dear. Lets have lunch some time, I can introduce you to more trans girls.” And with that she took the half eaten sandwich and left. 

	Lily looked excitedly at Rose. “Lets get home ASAP! I wanna do your first injection for you.” Rose just nodded. Poor thing, though Lily, it must be a lot for her. But Lily had spent long enough feeling alone. She had no intention of slowing down. She was confident Rose would thank her, in time.

	Rose drove them home. The whole time Lily smiled at her in excitement. When they got home she dragged Rose running to her room where she immediately started undressing her and putting her back in the short skirt and a top that left her tummy exposed. For good measure she put on the thigh highs as well, leaving them rolled up at the knees so she could get at her thighs for the injection. Before grabbing the bag with the supplies in it, she grabbed her makeup bag.

	“I want you to feel special. My special little doll sister. You’ll keep playing dress up for me wont you?” Lily whispered in Roses ear. Rose nodded. Lily painted her nails and told her to not let them touch anything while they dried. She applied foundation, a bit of eye shadow, some lipstick. Luckily Roses hair was a bit long, so with some brushing and a few hair clips she got it into a cute style, almost scene girl like. She stood Rose up in front of her full body mirror.

	It was subtle. Lily wasn’t an expert at makeup or anything, but still, the tears that welled up in Rose’s eyes told her she had done a good job. Rose was clearly still flat chested, but the bra helped add a bit of puff to the thin top. The skirt also gave the impression of flared hips. Rose touched the mirror, enchanted by how she looked in it. She didn’t realize when Lily pushed her onto the bed and gave her thigh a pinch and a poke with the needle. Lily cleaned and band aided the area while Rose continued to stare at herself in the mirror. 

	“There, all done.” She smiled. “You weren’t paying attention to what I did at all did you sis?” Lily giggled. “It’s ok, I don’t mind doing it for you.” She rubbed Rose’s thigh, hands getting dangerously close to the very visible bulge in Rose’s panties that the skirt didn’t cover. Rose let out a little moan.

	“B-big sis...” She stuttered, covering her mouth immediately. Embarrassed that she called Lily her big sis, but Lily just smiled devilishly. 

	“That’s right dear. I’m the big sis now.” Lily's hand crept ever closer to Roses panties. Grasping the top of them, tugging them down. “I’m the big sis, that means you have to do what I say.” She cooed. “Big sis has been soooooo lonely lil sis.” Rose was making little stutters, not quite words, just ah’s uh’s oh’s. She couldn’t protest when her girlhood sprung up from the underwear being tugged down.

	Lily stood and shoved Rose back down on the bed. “You’re my doll still right? You’ll still do whatever I want? No resistance.” She climbed on top of her, hand brushing her sisters cock while another held her shoulders down. “Big sis will make you feel special, don’t you want to be owned by her? Hasn’t she given you everything you wanted? Don’t you owe her what she wants now.” The words oozed into Rose’s mind. Everything happened so fast, it was too much to handle, she was overwhelmed. And it was so much easier to just do what her sister said. To just relax and let it happen. 

	“That’s right, good girl.” Somehow Lily’s panties were off, had she even been wearing them before? She guided her sisters cock into her pussy. “You belong to me.” She grasped Rose’s head as she began to ride her. “Say it back, say you belong to me.”

	“I-I, b-belong t-to y-you s-sis.” Rose stuttered out while enraptured by her sisters eyes. Gone were the innocent looks of happiness and excitement. Now there was something predatory. Lily leaned forward and exhaled on her sisters face before kissing her. Then she leaned back again and laughed, picking up the pace.

	“That’s right, you’re mine, you’re mine, you’re mine.” She still grasped Rose’s face with both hands. Her fingers played with the various soft bits, opening her mouth, touching an eyelid, scratching behind an ear.  “Say with me sis.” She sounded almost deranged at this point. Her breathy laughs coincided with wet thwacks against her sisters thighs, mixing with moans from the both of them. 

	“I-I’m yours. I’m yours. I’m yours!” Rose finally said back as she climaxed. Both arched their backs, Lily squeezed her thighs. She scratched at her dolls face. And then she lay on top of her. Mouth next to her ear. 

	“You’ll never leave me right? I’ll never be alone again right? You’ll sleep in my room, you’ll go out with me, you’ll do whatever I want right?” Lily’s voice was small this time, a whisper compared to before. She sounded vulnerable. She wrapped her arms around Rose’s neck in an embrace. “I would do anything for you.” She squeezed very gently.

	Rose returned the embrace around Lily’s back and said back. “Yes anything.” In just a breathy and weak sounding voice. 

	Lily smiled and whispered “That's my good little doll sister.”
