Just a Flash

Blake was woken up by the vibrating of his phone. It was a text from his sister: 'Did you forget to pick me up?'

"Oh, shit!" Blake whispered as he flung up from the bed.

His girlfriend, Laura, lay naked on the bed, her face buried in the pillow. "Mmm... what's wrong?" she mumbled.

"I gotta go pick up Jessica." Blake kissed Laura's shoulder and neck before picking his clothes up off the floor.

Blake's car revved into the parking lot and came to a screeching halt in front of his exasperated sister. Jessica had her arms crossed and head tilted. She rolled her eyes as she opened the door.

"So how was your first day of community college?" Blake asked as he drove off.

"It would have been shorter, if you had gotten here on time," Jessica said.

"Hey, you don't even have a license, alright? Beggars can't be choosers," Blake countered.

"So which bimbo were you busy banging this time?" Jessica leaned back and raised her eyebrows.

"Alright." Blake put a hand up. "That's none of your business."

"Was it... Britney?" Jessica flicked her hair and batted her eyes mockingly, imitating a ditzy blonde.

"What? No." Blake's eyes darted to the side. Technically, he was telling the truth, but if Jessica had asked that same question a week ago...

"Hmm... Laura then?" Jessica probed.

"It's complicated."

"So both."

"It's complicated." Blake gave Jessica a stern look. She raised both her hands and backed off.

"Besides, aren't you dating too?" Blake gave a suggestive nod.

"Of course not!" Jessica reeled back, remembering the cute guy she had met in class earlier.

"Um, defensive much?"

"Um, none of your business much?"

"Wha--" Blake was incredulous, but decided to just give it up. "Whatever," he sighed.

After a moment of silence, Jessica turned to Blake and nudged him playfully. "You're still taking me jet skiing this weekend, right?"

Blake chuckled. "Yeah. You ready for it?"

"Hell yeah!" Jessica beamed.

"Alright, calm down, Evel Knievel." Blake messed up Jessica's hair while she tried to slap him back.

***

"Oh my god, we're going way too fast!" Jessica yelled over Blake's shoulder as cold seawater drenched their bodies.

Blake looked back, laughing. "You doing okay back there?"

"Pay attention, you idiot!" Jessica slapped him and pointed ahead.

"Relax, you're going to be fine. Here, take a swim." Blake shoved a screeching Jessica off the jet ski.

When he circled back, Jessica was flailing wildly and screaming.

"Oh, come on. Don't be so dramatic. You have a swim team medal sitting in your room." Blake reached out a hand.

"I lost my bra, you asshole!" Jessica clawed her way up the jet ski.

"Oh, shit!" Blake's eyes became wide as he caught a glimpse of his sister's round breasts. He felt a sharp tinge in his crotch.

"Uuuggghhhh! I hate you!" Jessica screamed in Blake's ear while pulling his hair.

"Oh god, Jess. I'm so sorry... I-I didn't mean to--"

"Just take me back, goddamn it!" Jessica's voice cracked as Blake fumbled with the controls, keeping his eyes dead ahead.

"I can't believe this. It's so embarrassing." Jessica sobbed into Blake's shoulder as she clung onto him tightly, making sure her tits weren't exposed.

Blake swallowed hard and began to lose his breath as he felt his sister's firm breasts press against his back. To his horror, his cock grew rock hard and wouldn't stop throbbing.

When they got to shore, Jessica covered her chest with her hands and ran into the bathroom. Blake retrieved a towel from their car and knocked softly on the stall door. "Jess, I'm really sorry. I--"

The door swung open as Jessica snatched the towel from Blake's hand. Then she slammed the door shut again.

They were silent on the ride home. Jessica leaned against the window, her eyes red from crying. Her curly brunette hair was still damp as the afternoon sun shone on the smooth skin of her bare legs. She enjoyed the warmth while watching the orange horizon. Despite the awkward moment, Jessica was happy to have her brother keeping her company.

***

Blake lay on his bed, thinking about what he did and how he felt. He tried desperately to convince himself that he regretted pushing Jessica off the jet ski, that he was ashamed to have seen his sister's breasts. He was embarrassed, sure. But he couldn't deny the excitement in his chest and the throbbing in his crotch when he saw Jessica's supple, round tits. The only thing he regretted was not being able to see more of her body.

Blake slid his swim trunks off and grabbed his hard rod. He closed his eyes and thought back to that fleeting moment when Jessica revealed her forbidden fruits. He imagined how her curly brown hair would smell if he buried himself into her. He wondered how her moans would sound in his ear. He took a deep breath as the orgasm raced up his shaft.

Suddenly, Jessica appeared in the doorway. "Oh!" she yelped while backing out.

"Jesus!" Blake jerked up and scrambled desperately for his shorts. He stumbled around, nearly falling as he put them on, his back facing the door.

"Sorry. I should've knocked." Jessica peaked through the half-open door at her brother's bare back and for a second, his asscheeks.

"Uh, it's fine. Come in." Blake's voice was shaky.

"You don't need to clear your history or anything first?" Jessica tried to joke her way out of the awkwardness.

"N-no." Blake wasn't jacking off to porn this time.

Jessica stepped into the room. "Well, I guess we're even." She grinned shyly at Blake.

Blake chuckled, suddenly noticing how cute his sister was when she was embarrassed. "Yeah, I guess so."

He sat down on the bed and scratched his head nervously. "Listen, Jess. I'm sorry about what hap--"

"It's okay," Jessica interrupted. "You didn't mean to. Besides, I kind of overreacted. It's just... I feel a little insecure sometimes."

"Jess, you're beautiful. Don't even worry about it." Blake smiled warmly up at her.

Jessica looked down and blushed. "You think so?"

"Well... I would know, right?" Blake smirked.

Jessica giggled and kicked him in the leg. "Gosh, you could've slowed down before pushing me into the water. You owe me a bra." She pointed sternly at him.

Blake shrugged. "Well, it's not the first time I've went shopping for a bra."

Jessica gasped. "Really?" She plopped down onto the bed next to Blake, her eyes wide with gossipy intentions. "What size is Britney? And Laura? Wait, who's bigger?"

Blake smacked Jessica upside the head. "Your head, if you think I'm gonna tell you all that stuff."

"Ow! Fine, be that way." Jessica turned away with arms crossed. But she wasn't done annoying her brother. "Were they bigger than mine?"

"Oh for god's sake, Jess!"

"Come on. Just tell me. Be honest." Jessica cupped her breasts and looked down.

Blake scanned his sister's body for a split second before looking away. "Yeah, I don't know. They're pretty big." He never noticed just how supple Jessica really was. Her round jugs stretched the fabric of her tank top.

"But are they bigger than your girlfriends'?" Jessica pushed.

"I don't know, Jess. Should I invite them over to compare?" Blake grew exasperated, trying to suppress his own arousal. Jessica wasn't helping.

"Hm. Fine." Jessica seemed content.

"Why does it matter, anyway?" Blake asked.

"It doesn't. Just wondering." Jessica's eyes darted back and forth.

"You're trying to impress a boy." Blake realized it almost immediately.

"Well, there might have been this guy in class--"

"Alright, I'm getting my shotgun." Blake stood up.

"Oh, now who's being dramatic?" Jessica shoved him back onto the bed.

"You've known this guy for what, a day?"

"Three days." Jessica frowned and glanced to the side, realizing how pathetic that excuse was.

"Exactly. What if he's like some playboy or something? He won't treat you right."

"Hmm, I wonder who that reminds me of?" Jessica put a finger to her chin and pretended to ponder.

"If he's anything like me I'll kill him."

Jessica bit her lip and looked down, like a child who had been scolded. "You'd really do that for me?"

"I'd do anything for you, Jess. You're my sister." Blake softened up. "Just promise me you'll be careful."

Jessica nodded silently.

"And if you ever need anything, I'll be here. Always."

Jessica covered her mouth and looked like she was about to cry.

Blake sighed and rolled his eyes. "Come here." He beckoned her over.

Jessica sat on the bed and nuzzled up against him. He wrapped his arms tightly around her, smelling the sugary scent of her hair. He closed his eyes and tried to keep his thoughts clean.

"You're the best, you know that?" Jessica rested her chin on Blake's shoulder.

"Of course I know that," Blake scoffed. "Now get out of here."

"Oh, right. I'll leave you to it." Jessica gave him an exaggerated wink as he shoved her out the door.

***

Blake was bored out of his mind typing a report when Jessica's soft voice raised his spirits. "Hey Blake, you got a minute?"

"Of course! What's up?" Blake sprung up from his chair and shut the door, watching the swaying of his sister's hips as she made her way to his bed.

Jessica stroked her legs nervously, reluctant to start speaking. "You know how Ryan and I have been together for awhile now? Well, things are getting kind of serious. Like... you know..." She nodded towards the bed.

"I don't like where this conversation is going." Blake crossed his arms, frowning.

"Look, just hear me out," Jessica pleaded. "I can take care of myself. And I'll be careful like you said. But... I just don't know where to start."

"I'm not giving you the talk." Blake put his hands up and backed away.

"No, I'm not stupid! I know how it works. I just don't know the... techniques. You know, what guys like. I just don't want it to be awkward when we finally... do it." Jessica turned away to hide her embarrassment.

"Everyone's first time is awkward. You just have to get through it. Besides, what can I do that would help?"

Jessica swallowed. "You could... show me?"

Blake's eyes widened in surprise. "No! Absolutely not." He put his hands to his hips and paced around nervously. He was unable to comprehend what his sister was asking of him, but what scared him even more was that he was actually considering it.

"Come on, Blake! You said you'd do anything for me." Jessica tugged at Blake's arm.

"Alright, how about I just kill him instead? I said I'd do that."

"Blake! Come on, siblings experiment all the time."

"Yeah, with like, kissing and stuff. Not... not... that!" Blake was completely flustered and at a loss for words.

"Experiment can mean a lot of things." Jessica tried to come up with excuses. "Besides, you've already seen my boobs."

"That was an accident!" But Blake's eyes still lingered on Jessica's chest for a moment, remembering the heavenly sight that his sister gave him.

"Well, maybe you can accidentally drop your pants." Jessica bit her lip and walked up to Blake, unbuttoning his jeans.

"Jess, no!" Blake slapped her hand away.

"Come on, just show me what feels good." Jessica rubbed her palm against his crotch.

Blake gritted his teeth and grunted. The truth was, even her hand gliding over his cock felt amazing. It took him all of two seconds to become fully erect. He closed his eyes tight and tried, with every fiber of his being, to resist the temptation. But he didn't have the willpower. Plus, his nubile sister was so desperate. The playboy in him had a soft spot for girls who begged for it.

"Okay. But just for a little bit. I'll show you where to put your hands, and then we're done." Blake hated himself for agreeing to do this with his sister, but might have been more excited than she was.

He unzipped his jeans and let his boxers fall to the floor. He stared at Jessica, gauging her reaction as his erect penis came into full view. She didn't seem at all shocked, but instead gave him a quaint smile and nodded towards the bed.

They both sat down on the edge of the bed as Jessica rubbed her palms together. "Alright. So what do I do?"

"Just wrap your hand around it and... move it up and down." Blake's cock throbbed in anticipation.

Jessica wrapped her fingers around his shaft and tentatively stroked it back and forth. Blake let out a sharp gasp as a drop of precum appeared on the tip of his penis.

"Oh, that was fast." Jessica kept stroking, causing more to leak out.

"No, that's not—forget it. We're done."

"But wait. Is this the right way of doing it?" Jessica looked down, watching the precum flow down Blake's red cocktip, his stomach twitching with each stroke.

"Ugh... yes, that's how you do it. Now let go." Blake didn't want to have to cum all over his sister's hand. Because THAT would have been wrong.

"But does it feel good?" Jessica stared at Blake's face as her hand kept working his rod.

"Jessica, stop." Blake's voice began to falter.

"Just tell me if it feels good," Jessica whispered into his ear as her strokes became quicker.

Blake sighed exasperatedly. "Yes, it feels good. You happy?"

"Hmph." Without another word, Jessica got up and walked out of the room.

Blake let out a huge breath when Jessica's hand left his aching cock. He didn't even notice he had stopped breathing while trying to resist the sheer pleasure of his sister's soft, warm hand.

He fell back onto the bed and covered his eyes. "What the fuck?" he whispered to himself.

***

A few days went by filled with more than a few awkward silences. Blake tried to convince himself that it was a one-time thing, that he had already gone too far by letting his sister stroke him. But the damage had been done. He couldn't turn back now.

He knocked on Jessica's door. "Jess, it's me. Can I come in?"

Jessica opened the door and walked back to her bed without acknowledging him. Blake closed the door behind him and sat down next to her. "About what happened before..."

Jessica shrugged, avoiding his gaze. "Like you said, it felt good, so I did it right."

"Right." Blake took a deep breath. "But... I figured maybe I should return the favor. Just to show you what to expect, you know... when Ryan does his thing. I-I just don't want you to be surprised, thinking something's wrong."

Jessica glanced at Blake shyly. "You'd do that?"

Blake gave her a feeble smile. "Anything for my sister, remember?"

Jessica bit her lip and nodded. "What are we going to do?"

"Nothing serious. Just... he might play with you a little bit." Blake scanned his sister's smooth legs.

"Oh... how so?"

"It's kind of like what you were doing to me before. You know, with your hand." Blake remembered how Jessica had brought him to the brink of ecstasy.

"Sounds exciting." Jessica smiled playfully.

"Well, lay back and you'll find out." Blake winked at her.

Jessica lay flat on her back as Blake glided his hand softly over her thigh. Then he reached inside her skirt and toyed with her panties. Jessica let out a sharp breath as Blake's finger traced her slit.

"Oh wow. That's a new feeling." Jessica closed her eyes.

"You mean you've never..." Blake tilted his head.

"I have. It just feels so much better when someone else is doing it." Jessica smiled and gave off a light moan.

"Does it?" Blake grinned and flicked the tip of his finger over her clit.

"Mhm..." Jessica arched her back and shook her pelvis.

Blake was entranced by the sight of his sister writhing under his touch, and her moans made him rock hard. Jessica's supple tits floated up and down, teasing Blake and urging him on. He had to see more. "Maybe we should take off your panties. Wouldn't want them to get wet."

"God, am I leaking already?" Jessica glanced down.

"I don't know. Let's see." Blake tugged down at her skirt and panties.

Jessica's pussy was pink and moist. Blake could see that his sister was fully aroused, as her vulva expanded to reveal her hymen. It was almost as if she were inviting him in.

"Is it wet?" Jessica spread her legs and pulled her lips apart.

"Yeah, you're real horny, aren't you?" Blake looked at her suggestively.

"Whose fault is that?" Jessica punched him in the arm. "Well? Do I have to ask?"

"Oh, right. You want me to go all the way?" Blake was asking more for himself than Jessica.

"Well, you can't just leave me here all wet!"

"I could..." Blake pretended to get up.

"Blake! Keep going. I want to know what it feels like." Jessica grabbed his arm.

"Alright, fine. But only because you asked so nicely," Blake teased.

Jessica giggled. "I'll let you feel my boobs after."

Blake's smile disappeared and his voice lodged in his throat. "Uh, n-no. That's not what I'm here for. I'm just showing you the... you know." He looked for any excuse to save himself.

"Uh huh... right." Jessica squinted. "Well then. Whenever you're ready."

"Alright. Try not to scream too loud." Blake wondered if he could actually make his sister scream.

Jessica's laughter was mixed with her moans as Blake's fingers rubbed her leaking cunt. He didn't penetrate her all the way, but his fingertips brushed her hymen. He rubbed her labia and clit, feeling every bit of her virgin pussy.

Jessica's moans grew louder. "Oh god, Blake. Don't stop. Don't stop! That feels so good."

"Are you almost there?" Blake brushed her hair aside so he could see her orgasmic expressions.

"Yes, I'm so close. Keep going. Ohhhh..." Jessica clawed at Blake's arm.

Blake decided to finish his sister off by rubbing her clit. He flicked the tip of his finger in a circular motion around her little bean, making her grip the sheets and yell out in pleasure. To his surprise, Jessica didn't scream during her climax. Instead, she arched her back, opened her mouth wide, and let out a strained groan. He could feel her shivering intensely as she lost control of her body.

"Oh my god, that was amazing. I've never felt like that before." Jessica was out of breath.

"You need to work on your orgasm noise. You sound like a dying animal." Blake rubbed his fingers together, admiring the amount of fluid his sister gave out.

Jessica burst into laughter. "Oh, shut up! I do not sound like a dying animal."

"Well, you don't sound like anything that's alive," Blake retorted.

Jessica rolled her eyes. "How about this then? Oh Ryan, Ryan! Oh, you're so big, Ryan!" She faked a falsetto voice.

"See, that's better." Blake pointed in approval. "And you're appealing to his ego."

"Oh hush, you dick." Jessica sighed. "That really was amazing though."

"Good." Blake winked at his sister. "Now you know."

***

Blake was so hard at work that he dozed off at his desk. Jessica snuck up behind him and grabbed his shoulders. "So you forgot about something last night."

"Shit!" Blake jerked up. "Can you not do that?"

"Hmph." Jessica stood back and crossed her arms. "Did you hear what I said?"

"Uh, yeah. What did I forget?" Blake rubbed his eyes groggily.

"Well, you were supposed to show me what to expect during foreplay, but you left something out." Jessica shuffled nervously.

"Which part?" Blake was intrigued.

"You know... oral stuff," Jessica whispered.

"Oh... you want me to lick you up and down, is that it?" Blake grinned, trying not to seem too excited.

Jessica scoffed. "Only if that's what guys do... Is it?"

Blake rolled his eyes. "Maybe."

"Come on, Blake! I need to be ready," Jessica begged.

"Hmm..." Blake pretended to think about it, as if he hadn't already decided. "I guess you could also practice your moans."

"Yeah!" Jessica jumped up in anticipation. "So you'll do it?"

Blake shrugged. "Well, I wouldn't want Ryan breaking up with you so soon. Gotta make sure you're experienced."
