"I'm in here big brother!" Lisa shouted. The crème colored girl was kicking her painted toes back and forth over her ripe rump. Her attention was focused at some midpoint between her laptop where she was working on her blog and her television where some mindless drivel drama was playing out. In short the raven haired teen was spacing out when her brother entered the apartment.
Like a lot of girls who'd grown up in male households she'd never really realized that she was a woman. It wasn't that she was tomboy or anything, her favorite color was pink, she loved princesses and had dreamt of her marriage since she was twelve. Lisa did all the normal girl things but she'd never fully grasped modesty. At first it had been because she was too young and then as she'd aged it was simply because she didn't realize when she stopped being a girl and became a woman.
Brent was aware that his sister had become a woman though. It was hard not to notice with the way that she dressed. Just like the boys she had a habit of wandering around in oversized tee shirts and underwear but unlike her two brothers and father who may as well been wearing shorts and shirts her shirts tended to cling closely to feminine curves and she didn't wear boxers. Her panties were the current rage of boy shorts which might have covered her flesh but did nothing to conceal her parts. It might not have been as bad if Lisa had even the idea of what modesty meant but the concept was lost on her. When her brother entered the room from behind she didn't cross or close her legs. Lisa looked over her shoulder at him. "Whatcha need?"
It was always hard to keep his eyes from wandering his sister's flesh. She had filled into her body well by her eighteenth birthday. She'd had a tiny bit of an awkward stage where she'd groan tall but hadn't filled out but when she had it was like night and day. From gangly to gorgeous in just a matter of months and it was difficult to adjust to. She barely looked like the girl Brent had grown up with. She was a gorgeous woman and he was single and had been since his twenty third birthday. "I was just checking to see who was home." Brent lied quickly trying to drag his eyes away from his younger sister's crotch. Her panties had been drawn up between her legs offering a perfect outline of her womanhood.
Still completely unaware of herself Lisa crossed her ankles and spread her legs even farther. "Just you and me bro." She replied finally catching her brother's gaze which was focused on the corner of her ceiling. "Whatcha lookin at?"
"I . . . uh . . . thought . . . something. . ." Brent stammered letting his eyes wander back to his gorgeous sister. It was one thing to steal glances at her when she was unaware, but it was completely different to be staring while she was paying attention to him. "Sorry just you?"
The idea that her brother found her stimulating had never passed through Lisa's mind until she heard him stammering. She had to fight down a grin at the thought. It should have disgusted her but knowing that he was staring excited her. Lisa let her knees drift farther apart resting her ankles on her rump. The already indecent length of her shorts became scandalous as the fabric slipped into the crack of her ass. She felt it when his eyes grazed over her actually locked in place. "Yeah it's just you and me.
"Okay that's good." Brent spat. At the same time he spun on his heels escaping the cramped quarters where his younger sister was inappropriately lounging.
"Oh you aren't escaping that easily." Lisa rolled to her feet unplugging her laptop and followed her brother into the living room. "So how was your day?"
Brent looked up over the refrigerator door and right into another reminder that his little sister was a woman. This time the reminders were the dark circles of her nipples easily visible through the skin tight white shirt she was wearing. "Okay." He replied burying his face in the fridge while he composed himself and when he came up he was looking at her face. "You sit around here all day?"
"Mostly." Lisa replied walking up and then getting up on her toes so she could lean over the refrigerator door resting her breasts on it. Turning away from her brother she leaned as far in as she could manage snatching a bottle of water.
It wasn't fair, she wasn't even aware of the things she was doing but Brent was. He was battling to keep the blood from rushing to his waist at the same time as he was trying to conceal the effects. "Any calls?" Brent asked chancing a glance upward. Lisa shook her head tossing her dirty blonde hair over her shoulder with the same movement.
For a moment Brent's eyes met blue stare and he was trapped there for a moment. There were lots of things he'd noticed about his baby sister since she'd grown into her body but her smoking eyes weren't on that list. Neither was way her lips curled when she was getting what she wanted. "That's not even right. You're teasing me." Brent said slowly trying to convince himself as much as her.
"So what if I am?" Lisa answered snidely. She slid onto a stool and dramatically crossed her legs. The fabric of her shorts predictably rode even higher.
"I might have to teach you that it's not right to tease men." Brent shot uncertain if he was joking or not.
The twisted lips shifted into almost predatory smile. "No you won't. You're a wimp." To prove her point she unscrewed the top of her water and poured just enough of the chilled water onto her breasts to make the already thin shirt transparent and her nipples rock hard. "You know Dad won't be back for hours and Dave never comes in until midnight."
"I'm not gonna fuck you. You're my sister. It's gross." Brent said flatly. His eyes hadn't once moved from his sister's flesh when he spoke.
"You're right. You're not gonna fuck me. Not because it's gross though." She spread her legs until she was straddling the stool and then poured more water down her belly. The soaked fabric gave a perfect outline of her young ripe nether region. "You're not going to fuck me cus you're a pansy." She rolled her hips like a dancer allowing the wave to travel the length of her spine. "And you know how I know you're a wimp?" Lisa let her head hang backwards thrusting her chest toward him. "Because I can feel you looking at me, you were checking out my ass when you came in and you don't have the balls to come over and take what you want." Lisa brought her head back up slowly and found her brother standing silently only inches away from her.
"Stop teasing. It's not cute." He was intentionally slowing his breathing. She could hear the effort he was making to sound normal. "And besides what if I call your bluff?"
Lisa took a deep breath and leaned forward as far as she dared. Their chests were nearly touching when she stopped. "You've been my brother for eighteen years. You know I don't bluff." She smiled then leaned forward quickly kissing the tip of his nose before retreating. "But since you're a wimp I'm gonna go for a walk around the block. "I'm sure I can find me a man." Lisa didn't wait for a response; she turned and started towards the door.
She managed to take a single step before he gripped her shoulders and spun her around to face him. The look in his eyes made Lisa gasp. He didn't look like her brother. There was a fire there that Brent simply didn't have and it frightened and excited her equally. "You're hurting my arms." The complaint sounded so weak in her ears that it didn't surprise her when her brother tightened his grip and shook her. "Let go."
"Why? I thought you wanted to see me man up?" Brent grinned and leaned forward pushing his nose into the nape of her neck and inhaling her scent. "Weren't you about to go take a walk looking for a man to do just that?" Brent wasn't much bigger than his sister which always made it so surprising how much stronger he was. Lisa realized just how helpless she was when he twisted her around and pushed her against the wall holding her on the tips of her toes. "Still thinking you want me to man up?" Brent growled bumping her against the wall again.
For a moment there was silence as Lisa stared down at the man she barely recognized. Then he started to quickly fade and Brent returned. She knew because he let her stand and his fingers were just holding her, not digging into her flesh any longer. The storm she'd seen brewing in his eyes had waned as quickly as it had brewed. "You almost had me scared bro." A smug grin had just enough time to form before the storm returned suddenly to his eyes and he jerked her against the wall again.
Brent struggled for control as tremors quaked through his body. He had never let anybody call his manhood into question and his sister was well aware of that fact. It was a sure fire way to get him into a semi-rational craze. He could already feel the fog settling on his brain the only thing keeping it at bay was the fact that this was his sister, not some punk on the street. The thing was she didn't really look like his sister, not anymore. Lisa would forever be a doe eyed twelve year old, not this sexual ball of curves he was pressing against the wall. It took a moment to get control and let her down.
The moment Lisa was free she spun toward the door. "That's what I thought." She tossed her hair casually over her shoulder and took one step. This time when her Brent seized her he threw one arm around her chest and other around her waist. The sudden attack made her squeal. Instinct drove her hips back against him. One part of him was undeniably male. Lisa tried to get herself loose but Brent held her in place.
