"You little pervert!"
The voice behind him startled Ryan Chambers. He swiveled his chair around from the computer to discover his older sister, Rachel, standing in the doorway to his bedroom laughing to herself. Ryan quickly clicked on the Home button of his web browser so his sister wouldn't see what he had been looking at.
"Too late, Ryan. I know you were looking at porn. Are you old enough to look at this anyway?" his sister said with a laugh as she walked over to him.
"Oh shut-up!" her brother snapped "I'm eighteen and can look at whatever I want."
"Shouldn't you be in school?" she asked.
"I skipped last class. Shouldn't you be at work?" he retorted.
"I have Tuesday afternoons off. You know that."
Rachel took the mouse in her hand and clicked back to the previous page to see what her brother had been looking at.
"flashyourtits dot org... what is this?" she asked as she stared at the picture of a topless woman on the screen.
Ryan felt himself blushing. "It's... ahh... you know, one of those sites where women or their boyfriends send in photos of their tits and people rate them." he explained.
Rachel leaned over her brother's shoulder and brushed her long brown hair out of her face as she looked at the web page. As she bent over Ryan looked out of the corner of his eye into the opening of his sister's blouse. He could see a hint of her left breast and the white lace bra she was wearing. He felt himself getting hard again. Rachel's round breast swayed slightly with her movements and Ryan wondered how it would feel in his hand.
"These women aren't so hot." his sister scoffed "My boobs are as nice as theirs -- maybe nicer."
Ryan smiled but didn't respond. He secretly agreed with his sister though. For the past few years he had stared at Rachel's breasts every chance he got, but to see her topless and feel them was his greatest desire.
"Well...?"
"Well what?" Ryan asked as he looked up into his sister's brown eyes as she stood next to him.
"Are mine as nice as the ones on that site?" she demanded.
Ryan shrugged.
"Oh come on, Ryan... you stare at them every minute I'm around you. Don't try to play innocent!"
"Ah... I guess they are." he offered.
Rachel looked down at her chest and smiled at her brother.
"Heh... I should send in my picture sometime. I bet I'd get a higher rating than some of those girls." she said.
"Probably." her brother acknowledged, feeling bolder.
Rachel watched her brother's eyes as they moved down to her chest and she felt herself getting wet. She would never dare to admit it to anyone, but she often felt a rush of excitement when she caught Ryan staring at her and enjoyed teasing him. She knew he would never dare do or say anything so she felt that her games with him were safe because they would never go beyond him looking.
"You really think so?" she asked.
Ryan smiled and nodded. "Sure."
"At least they're bigger than hers" Rachel said gesturing to the picture on the monitor.
Ryan was surprised and turned-on by his sister's candor and decided to see where the conversation would go. "Her profile says she has a B-cup..." he said as he scrolled through the page.
Rachel let out a faint laugh. "Yeah, well, mine are a C, so I've got her beat."
"Oh..." her brother said as nonchalantly as he could.
"Ya, right... like you couldn't have guessed that. Cut out the bullshit, Ryan, you've stared at them enough to know they're more than a B-cup." she said as she playfully shoved him.
"I... I didn't know... how could I tell... besides, I thought you'd be pissed-off at me." he stammered.
"Nah, it's ok. I don't mind. You can look if you want. Let's just keep that between us though, ok?" Rachel gave her brother a wink and smiled.
"Ah... sure... of course!" he said, unsure of how to react.
"I should get going. Mom and dad will be home in less than an hour and I promised mom I'd start supper. Don't pull it off looking at those pictures, okay." his sister said with a laugh before she left his room.
Ryan gave a deep sigh after he heard his sister close his bedroom door behind her, then turned back to his computer. He looked through several more photos at the website, but couldn't get the image of his sister's breasts out of his mind. With her downstairs he didn't dare take his cock out and stroke it like he wanted to for fear she'd return so he began doing homework in an effort to concentrate on something else.
Throughout dinner Ryan felt nervous around his sister after their conversation that afternoon so decided to go to a friend's house that night rather than risk the chance of her teasing him while their parents were around. He told his parents he'd be out late so they wouldn't worry then left.
The houselights were out when Ryan returned home and he quietly came in and went up to his bedroom. He got undressed and slipped into bed. His thoughts returned back to his sister as he lay there in the dark. He pulled his boxers down and began to slowly stroke his hard cock, spreading precum over the head. The light rapping at his door a few minutes later made Ryan jump and he quickly pulled his boxers back up.
"Ryan... you awake?" his sister called out in a hushed voice.
"Ya... what is it?" he asked, careful to be quiet and not wake his parents.
"Can I come in?" she asked.
Ryan told her to come in and sat up in bed. He turned on a lamp on the nightstand and watched as Rachel walked into the room. Her hair was slightly messed-up from where she'd been laying in bed and she was wearing a thin white cotton robe that fell to just below her knees. She sat on the bed next to him and tucked one leg under the other. Ryan looked down at her bare thighs as her robe fell open below her waist and felt his cock twitch.
"So I thought about it, and I want to put my picture up." she said.
"What?" he asked, confused.
"That website you were looking at this afternoon... I want to put my picture on it. But not showing my face, just my boobs." she told him.
"Oh, okay." Ryan replied, not sure why his sister was divulging this to him.
"But I need your help, Ryan."
Ryan sat up straighter in bed, shocked by his sister's comment. "What?" he asked.
"I need your help. You have that digital camera mom and dad got you for your birthday, plus I have no idea about how to put pictures on the Internet. Will you do it? You're the only one I trust to do this and not tell everyone about it, Ryan."
Ryan drew in a deep breath. "Rachel... geez... I'm your brother. I can't be taking pictures of your tits!" he told her.
"After all the times you've stared at them?! You've already seen most of them when I bend over in tank tops or whatever. What's the difference? Will you, please? It'll be fun." she said as she clutched his thigh, causing his cock to throb even more.
"I don't know about this..." he said.
Rachel slid closer to him on the bed and smiled. "Can you honestly say you've never wanted to see them?" she asked.
Ryan never answered.
"This is your chance, Ryan. Me... topless." Rachel was grinning.
Ryan smiled despite his embarrassment. "You're bad! Are you sure about this, Rachel?"
"Sure I'm sure. I've been thinking about it since this afternoon. It's sexy, and naughty. Besides, no one will know it's me -- except for you, little brother." she said with a wink.
"Okay, fine. Some day when mom and dad are gone we'll do it." he said.
"No, now! Before I lose my courage and change my mind." she said tugging at his arm.
"Now, with mom and dad down the hall, are you nuts?!" Ryan said.
"Don't worry, they're sound sleepers. It'll only take a few minutes. Get your camera." his sister said.
"Okay... but be quiet." he answered, somewhat reluctantly.
Rachel moved to allow her brother to get out of bed. As Ryan stood up he realized that his cock was creating a tent in his boxers and he tried his best to keep his back to his sister as he retrieved his camera from his desk drawer.
"It looks like you're up for this." she said with a smile as she looked down at the bulge in her brother's boxers.
"Oh shut up!" he snapped defensively.
"Sshhh... you'll wake mom and dad." she admonished then looked down at him again "Is that... because of me?"
Ryan gave a faint smile and nodded.
Rachel slid closer to him so their bare thighs were touching. "Have you... umm... have you ever wished you could see them?"
"Of course." Ryan admitted, deciding there was no need for pretense now.
"Well, go ahead..." his sister said as she sat up straighter.
"What?" Ryan asked.
"Go ahead... open my robe, Ryan. This is what you've wanted... take a good look at them."
Ryan's hand was shaking as he reached out towards the belt of his sister's robe. Her nipples were now hard as bullets. He slowly took one end of the belt between his fingers and gave it a gentle tug. He looked up at her face, waiting for her to stop him, but saw her smile back as she watched his hand.
"Open it up, go on..." she encouraged him.
Ryan tugged the belt loose and Rachel's robe opened slightly to reveal a narrow strip of skin that stopped at the black lace panties she was wearing. Ryan ran his eyes up and down, noticing a hint of cleavage. He smiled at his sister who licked her bottom lip. Her nipples were beginning to poke from her robe and Ryan wished he could suck on them.
"All the way..." she breathed.
Ryan felt like his twitching cock was going to explode at any second. He ached for relief. He raised himself up on his knees and saw Rachel look down at his cock pointing towards her under his boxers. He reached out and took hold of the sides of his sister's robe and slowly opened it, then gave a broad smile as her breasts were revealed to him... finally. They were bigger and rounder than he'd imagined, capped with small aerolas and light brown nipples that were now thick and hard, like his cock.
