Kate was beautiful and she knew it. She was tall and slender, but with a nice full D cup that was all natural. She had long hazelnut brown hairs that matched her eyes and her lips were just perfect. She could get any guy and currently she was with Travis. He was good looking and perhaps more important to her.. he and his parents had money. She loved getting gifts from him and in return she touched him and allowed him to touch her. For a 22 year old, she acted like quite the prude... but the truth was that she wanted as many gifts from him as she could. Letting him fuck her too soon, would be counter productive.

The only thing that she hated about Travis was his younger sister. Emily had long blonde hairs, green eyes and rather attractive. The reason Kate hated the girl so much was because the girl had tits that made Kate's D cup look small. She didn't like feeling inferior, so she did all she could to ignore the 18 year old girl.

"Oooh Travis... it is beautiful" She held out the necklace that had come from the little box and studied it. It surely had cost Travis quite a bit of money and that had to be rewarded... Eagerly her lips found his for a passionate kiss on his bed. If his hands played well, the kiss could become a caress but that was as far as she went with him for now. Guys that got what they wanted, were guys that lost interest.
 
"Thanks, I'm glad you like it." Travis smiled as the usual sense of giddiness tickled along his spine. Though he and Kate had been going out for some time now, part of him still couldn't believe she was actually dating him.

He could still remember her from high school. Kate had been a couple years older and captain of the cheerleading team. She'd stretched out her tight little sweater far more than any of the others and her lithe legs seemed to go on forever. He and the entire male population - and probably a sizable portion of female population as well - had monster crushes on her. Consequently when he'd encountered Kate for the first time in years and she'd openly flirted with him, he could scarcely believe it.

Still, things hadn't progressed quite as he'd hoped. Kate had been a bit more aggressive than any of his previous girlfriends. She liked to flaunt her body, wearing outfits that emphasized her curves and her endless legs. She also didn't hesitate to rub said body up against him, apparently delighting in how it excited him.

But despite her apparent forward nature, the level of physical intimacy had seemingly stalled. While Kate was an outstanding kisser and certainly her hands roamed rather freely, she'd insisted their clothes remain on. She'd let him fondle her nether regions with a hand up her skirt - even to the point of climax - but always on the outside of her silk panties.

Kate had her explanation, of course. Travis wanted to believe her. Staring up at the auburn tressed beauty, he wanted to believe that the aching blue balls she'd left him with for weeks was definitely building to an epic sexual experience.

But he was finding it increasingly difficult to ignore the negative interpretation of events his sister maintained. Emily contended his girlfriend was just a tease - that she got off revving Travis' libido without offering release.

Travis shoved his doubts to the back of his mind as Kate swung her leg across his hips. Tonight would be different. Tonight Kate would give him the satisfaction he yearned for. No more would he be reduced to stroking himself to completion in the bathroom.

He slid a hand up her left thigh to the edge of her skirt. "Why don't you show me just how much you like it?" he suggested. "Why don't you take off your panties?"
 
A sudden look of shock came on her face as Kate looked at him. "What? Is that why you gave me this? Because you see me as some hooker? A whore that needs to get paid to give you some attention?" She asked him, making clear how terribly wrong he was if he thought that. Of course... in a way she was, even when she never would consider that herself. She brought her hand to his pants and stroked his cock, jerked him even slightly through his pants. "Gods... you do...! I take things slowly because I love you so much and want to spend my life with you while you only think with your cock..."

She even had tears in her eyes... and all of that without any acting classes. "We have a great time together... why do we have to rush things? We already do many intimate things, just allow me to do things in my own speed... but if you think your necklace deserves my panties... you can have the necklace back." Of course it would be much harder to separate with the necklace than with her panties, it really looked expensive. But she hoped to know Travis well enough to know he would back down and let her keep both the necklace and her panties.

He would say the right things and she would allow him to make her cum while she still wore her panties.
 
"C'mon, Kate, you know that's not true!" Travis burst forth. "You know that I don't give you things because I'm expecting something in return! I'm not like that."

Dammit! He'd thought a simple suggestion like that would be just the thing to edge her into something new. Somehow that'd wound up being evidence that he was an unloving jerk. How had Kate's emotional judo left him on the defensive?

His prior dating experience certainly provided no help. He'd never had a girlfriend take this tack before. His prior experience in overcoming female reluctance was limited to assuaging fears about his size. (Even flaccid, the sheer thickness of his member could make them weak in the knees.)

That hardly seemed to describe Kate. One of her favorite activities was to arouse Travis till he looked like he was smuggling a salami down one leg of his pants; she'd then straddle that thigh and grind her panty-clad pussy against the denim-covered bulge until she came. If she truly was uncomfortable with his size, she was doing a great job pretending otherwise.

But Jacob was at a loss for an explanation for this glacial pace. Neither of them was a virgin saving themselves for marriage. They had dated long past any reasonable modern standard for saying they were rushing to jump into bed with one another. Both of them clearly had healthy libidos. Kate certainly seemed to find him sexually attractive. Everything seemed greenlit fr greater intimacy. Yet still Kate held back.

"I'm not trying to rush you, Kate. Truly I'm not. I want you to be comfortable. I want you to be happy. But...."

Travis wanted to continue by asking whether Kate felt the same with his needs. But the words died in his throat as he saw the tears in her eyes. Great, he was about to make her cry.

Travis felt his will crumble. He knew this was a conversation that needed to be had. He couldn't take much more of the waiting. But he just couldn't bring himself to force the issue right now. He'd just be another stereotypical horny guy pressuring his girlfriend into sex. He'd be the jerk that made her cry.

"Okay," he sighed. "Okay. If you're not ready, you're not ready. We'll go at your pace, okay?"
 
Kate gave him a weak smile and nod, but inward she was fully grinning at her victory. The truth was that if Travis hadn't made his comment, she might have allowed him to remove her panties... the necklace really was worth a lot. But she couldn't have him thinking there was a link between presents and sexual favors, so he had screwed himself out of it.

She kissed him to show things were ok again. And as she kissed him, she let the kisses grow more eagerly. Soon she was on top of him, brushing her crotch against his cock while they were making out. She still couldn't believe how big and hard he felt and it would be quite the experience to feel it inside of her for the first time.

Her mouth left his lips and went to his ear. She didn't whisper anything naughty into it, instead she suckled on his earlobe. She really had some good tricks that guys liked.
 

Their make-out session intensified. Kate began teasing his earlobe. Jacob thought it rather ridiculous that he enjoyed it so much, but it really
did wind him up.

Jacob returned the favor by kissing along the side of her neck. His lips traced along the artery, feeling the
pulse of her artery beneath the smooth skin.

He also took the opportunity to slide his hands beneath her skirt. He slipped them around her ass, pressing each hand into the firm, round flesh. His fingertips told him that she was wearing a thong tonight. The thought of her nearly naked ass made him groan aloud.

They were both starting to make some noise. Kate was pumping her hips as she ground her pussy against the outsized bulge running along his right thigh. The bed frame creaked slightly as her intensity increased.

Jacob smiled slightly - this was probably annoying Emily. He and Kate always came back to his house because his parents were often away; unfortunately, his sister almost never was. With her bedroom next to his, complaints about the noise were fairly regular. Well, tonight he'd give his sister something to complain about.

Of course, Emily could readily solve the problem by actually developing a social life. While the big brother in him at times made him reluctant to admit it, his sister was crazy attractive. (Having been a staunch admirer of the female form since he hit puberty, Jacob found it rather disconcerting to acknowledge that the most magnificent set of curves he'd ever seen belonged to his little sister; she put Jessica Rabbit to shame.) But Emily seemed uncomfortable with her physical appeal, preferring to conceal her amazing figure. Jacob knew she attracted plenty of interest, but she hardly ever went out with anyone. (He wasn't even sure whether her interest favored boys or girls.) Instead, she hung out at home, cramping his style.

Jacob pushed thoughts of his sister aside as he focused on the task at hand. Kate sounded like she was getting close to cumming. Perhaps with a couple of orgasms out of her system, she'd be more amenable to trying something without clothes.

The challenge for him was lasting that long. Kate's grinding felt pretty good - even through the denim. If he wasn't careful, he'd get too near the edge to stop and it'd be game over. But if he could hold out, maybe he had a shot at something more than dry humping.

Jacob squeezed her butt and helped her grind against him. "C'mon baby, cum for me," he urged.
 
Emily rolled her eyes as the sounds from the other room made it into hers. Kate was a loud one and the walls were very thin. The sounds upset her for various reasons, the most important one being that she didn't think Kate was right for her brother. But there also was a hint of jealousy, she wasn't good with guys.... the only guy she really felt comfortable with was Travis and during the times he was single he was close with her. But when he had a girlfriend, he was always busy with them.

Guys seemed to prefer her breasts more than her and that made things complicated. When they spoke it seemed to be directed at her breasts as they stared at them. So she often tried to hide them, but that really was impossible. Shopping for her upper body was also hard. She wondered how it would if a guy made her cum as Travis did Kate.... and by the sounds of it, Kate just reached her climax.

With a groan, Emily left her room and went to the bathroom. The bathroom was the only room that blocked the sounds and the sound of the shower would do the rest. She undressed and got under the shower. She didn't bother with shampoo, instead her hand immediately went to her pussy, eager for an orgasm of her own.
 

Jacob could not resist a grin as his girlfriend began to cry out with her second orgasm. Kate was always a vocal performer, so her moans bounced off the wall. She also put on a bit of a show - tossing her head back and squeezing her breasts as she shook with pleasure.

Jacob also felt a bit of pride. Not only had he made this beauty cum, but he'd managed to hold on till she did it twice. Usually he was ready to pop not long after her first.

Still, he'd only just managed this stamina by the skin of his teeth. The denim around his leg looked like it'd been painted on thanks to his swollen cock. He could feel Kate's warm juices seeping in through the fabric and felt a desperate need to expend some of his own.

Hopefully his current agony was worth it. He'd given her two orgasms and she was still fully clothed. By any fair standard he ought to get blow job in return. Hell, he'd be happy if she just used her hands. He dreaded the prospect of having to finish himself off alone in the bathroom - it was so humiliating.

"Kate," he said when she'd recovered enough to meet his gaze. "I'm really close to cumming. Really, really close. How about we take off my jeans and you finish me off? Please?"
 
She weakly shook her head. "Maybe next time... when we have the house to ourselves." She half promised. Kate kissed him and then rolled away from him. "Think of me." Clearly she expected him to leave the room to get what he craved.

Then she took the necklace and admired it more. "It really is beautiful, thank you." She spoke with a big smile and brushed her finger against it. It was a good sign Travis was willing to spend so much money on her.
 

Travis groaned. He had half a mind to argue with Kate. Who the fuck cared whether Emily could hear? Hell, Kate made plenty of noise and that didn't stop her!

But what little self control he had left waved him off. His lust howled like a pack of hungry dogs and his grip on the leash was weakening. If he didn't get relief soon, he was going to lose it. And if that happened, he didn't trust himself. He might do something he'd regret.

No, he couldn't afford to argue with Kate in this state. Get away, blow off some steam, settle down. Then he could discuss what his expectations were for his girlfriend.

Fuming, Travis lurched to his feet. His engorged erection made even walking awkward. He lurched down the hall to the bathroom. A quick masturbation session was exactly what he needed to relieve the pressure. He grabbed the handle and hobbled inside, his other hand already unzipping his jeans.
 
"Ohhh..." Emily moaned as she twisted her own nipple while two of her fingers were deep inside her pussy. She loved the hint of pain rushing through her pussy as she played with herself. She didn't hear how her brother opened the door... and with the thick walls of the bathroom it was not really weird he didn't hear the shower running. Still... if one paid attention, the water was clearly audible.

"I am... going to cum... mmmm..." Emily moaned to herself, not aware Travis was in the room able to over hear her. She wasn't fully there yet, but it was only a matters of seconds.
 

Travis entered the bathroom and walked right into a cloud of steam. The shower doors were closed, but pressed up against the frosted glass was the hazy figure of a naked body. Given the occupants of the house, it had to be Emily.

Travis felt his frustration begin to simmer. First his girlfriend denied him satisfaction and now his sister was in his way. Life truly did want him to
suffer.

Travis opened the shower door a crack to let his voice carry. Steam rolled out through the gap - Emily liked a hot shower.

"Dammit, Emily!" he barked. "Get the fuck out! I need to use it and you're in the fucking way!"
 
Emily nearly jumped out of her skin as the shower door opened... or actually when she heard Travis' voice. She turned towards him, her fingers still deep inside her pussy making it awfully clear what she had been doing. Slowly she pulled them out of her and it was clearly visible they were differently wet than the rest of her body.

"Fuck me Travis... You can wait your turn." Even with the steam she saw his pants opened and the bulge that tried to hide or tried to spring free. She licked her lips without realizing it. When they were young they had showered together but his cock hadn't been that huge back then.

She was very much aware that she hadn't reached her climax yet and hoped Travis would soon leave her alone.
 

"Fuck you Travis... You can wait your turn. Emily leaned an eye into the gap and glared at Travis. She crossed one arm in front of her body trying to shield her naked torso from him. She should have used both arms - her tits were too large for just one.

Travis lost all patience at this point. The load weighing down his scrotum was going to be immense. If Kate wasn't going to let him fill her belly with it, the only safe place to fire it off was within the easy-to-clean confines of the shower. He damn well was not going to let his baby sister deny stand in his way.

"Fuck that, Emily!" he retorted. "You've probably been in there 20 minutes already. It's time to get out!"

Travis stripped off his shirt. He then attacked his jeans. He groaned as the denim freed his trapped cock. The massive shaft actually increased in girth - the denim confines trapped it too tightly against his thigh. The base was still concealed beneath his boxers, but the thick glans was clearly visible well beyond the Navy Blue cotton.

"Last chance, Em! Come out, or I'm coming in!" He waited several seconds, then yanked the shower door open and stepped inside.
 
Emily let out a high yelp as her brother joined her shower and quickly brought her arms up. She needed two arms to cover her huge breasts, but even then she failed miserably at hiding them. They just were too big. "Travis... You can't... What.... get out.." Then she noticed his cock and gasped... unable to look away from the thing. It was the first cock she saw for real and not in pictures or movies.

"I.... you... Travis.... Fuck...." None of that was an actual sentence or suggestion, but still she felt... and sounded... rather aroused. She had been close to an orgasm and still was as her pussy kept burning and her nipples felt hard against her arms.
 

Travis expected Emily to flee. He had a significant physical advantage on his younger sibling. Her preferred form of confrontation typically involved yelling at him from across the room.

Emily, however, didn't back away. She closed the distance. She dropped her hands away, revealing her gorgeous tits. God, even her nipples were huge. Hard, too - a fact he discovered when she stood close enough for her breasts to press against his chest.

He felt his boxers slip free of his waist and plop in a sodden heap at his ankles. Freed of its last restriction, his cock swung immediately up to horizontal and beyond. Emily stood right in its path.

She winced slightly as it slammed into her tender V. But she stood her ground - albeit on tiptoes. His sister was literally straddling his cock.

Travis groaned slightly. His sister's damp pussy lips were spread wide trying to ride the massive pole supporting her. After repeated failure with Kate, this was the closest his cock had been to a vagina in two months. He was tired of waiting.

"Emily," he growled, his last bit of willpower fading fast. "I need to blow my load in the worst way. This is your last chance. Either get out, or decide whether you'd rather fuck me or suck me."
 
"Travis..." She pleaded, not sure how to handle the situation. She moved her hands, but she could hardly push him out of the shower. There really wasn't much room for the two of them to stand and when his boxers dropped his cock nearly instantly between her legs, brushing against her pussy.

She gasped when her brother spoke, not believing the words coming out of his mouth. "Travis..." She made a single move closer to the shower curtain but with her brother standing between her and the curtain, and his cock between her legs, his hard on now was on the edge of invading her pussy. The feeling caused her to moan
 

Emily didn't move off her position on Travis' cock. Instead, she just tried to balance herself atop it and moaned.

Travis grinned lasciviously. "I'll take that to mean 'Let's fuck'."

Travis reached past his sister's gorgeous breasts and gripped her underarms. Grunting, he lifted his sister into the air. Even with her incredible curves, his sister was fairly petite and he was quite athletic. Even so, it still took considerable effort to lift her high enough.

When he lowered her, Travis aimed her pink pussy at the swollen head of his cock. It took a few tries, but he managed to line up the tip so that it sank into her.

At first, it just stopped. Travis had a brief moment of panic. Maybe Emily was just too damn tight for his monster cock.

But as Emily screamed, her pussy lips distended further and further until finally the massive cockhead popped inside. Travis groaned with relief as inch by distorting inch disappeared inside his sister.
 
"Travis! Oh Fuck! Oh god...!" Emily couldn't believe what her brother was doing and screamed as his huge cock seemed to rip her apart. He was so full and big. She came when the head of his cock was completely inside of her, causing her legs to go weak and losing balance. But that only resulted in more of his cock ending up inside of her.

"Oh fuck... what are you doing to me... Travis... fuck..."
 
"Fucking hell!" Travis grunted. His sister was ridiculously snug around his cock. He'd had condoms fit more loosely than her vagina.

Still, she seemed to enjoy it. His sister shook and moaned at the very entry of his glans into her pink love tunnel. He could feel her warm juices dripping down his shaft.

Travis responded by shoving another few inches into her. He was likely seconds from blowing and he was going to make damn sure he did so deep inside her pussy.
 
Kate spent a while admiring her new necklace and when she was 'done' with that for now she was surprised Travis hadn't returned yet. Normally it only took seconds before his hand had finished what she wouldn't give him yet. Part of her was curious about it, she had lots of experience with guys but seeing one jerk was actually rare.

She got up from the bed and walked to the bathroom. Of course it was very 'dangerous' what she was going to do, it easily could turn into sex rather than just watching but here she was. She opened the door and heard the sounds of the shower... and soon heard the other sounds as well.

The curtain was still mostly open so she could immediately see what was going on. Brother and sister doing 'it' and Kate gasped at the sight. Perhaps it was the necklace that had gotten her in a good mood, perhaps it were the orgasms Travis had given her, Kate wasn't sure what it was but she found the sight turning her highly on.

"Fuck her... fuck her hard... Travis... fuck your sister... Make her cry and scream." Of course there was sweet justice in letting Emily be fucked by Travis' monster, the girl would pay for making Kate jealous.
 

Travis pinned his sister against the slick tiles of the shower wall. He plowed as deep into her as her tight little pussy would allow. A distant part of him recognized that he was far too big for her to be so forceful, but his lust had driven him beyond reason.

It didn't take long. Kate's previous efforts had him aching for relief even before he entered the shower. With his cock now buried in a warm, moist pussy, his explosive climax was inevitable.

He grunted like a bull as the first thick jet of cum flooded into Emily. Several more powerful gushes followed, filling his sister's belly with his seed.

Only after the wave of delirious relief did he become dimly aware that someone was speaking to him. Someone. . . behind him?

He turned his head and was surprised to see Kate standing just outside the shower. Had she been watching? How much had she seen?
 
If it wasn't for the huge cock that seemed to impale her, Emily might have jumped 6 feet into the air at the sudden sound of Kate's voice. The startle of Kate's presence and the shock of what the girl was saying seemed to make her pussy even more tight and it was not really a miracle that Travis came at that exact time. She felt disgusted, she felt like crying and at the same time she wasn't sure this wasn't what she had wanted.


"Keep fucking her... You are still hard right...? Fuck your sister... see if you can make the slut cum too..." Kate encouraged Travis. She could tell Emily was more in the mood to leave than to continue... but she really didn't care. She wanted Emily to get used as the slut she was.
 
Travis was momentarily stunned. He expected Kate to be shocked or horrified. Surely seeing your boyfriend balls deep in his little sister had to be upsetting.

But Kate didn't seem upset. She seemed . . . excited? Indeed, her nipples were as hard as rocks and her cheeks were flushed. She looked like she did when she was dry-humping him in bed.

Anger welled in him. He'd been trying for weeks to get Kate naked without success. And now she was extolling him to fuck someone else.

And yet it was working. Despite his recent explosion, his cock was swelling again. Emily was clutching her lower belly as it distended trying to accommodate his thick shaft and their copious commingled fluids.

Still, he couldn't give Kate a free pass. "Don't be a peeping Tom, Kate," he snarled. "You want to watch, then get undressed and get in here. Otherwise, get out."
 
Without much hesitation Kate stripped and stepped into the shower, that now really was full. Her breasts were against Travis' back. "Pull on the slut's nipples..." She whispered into his ear and then kissed his neck. She really was feeling hot.


Emily was shocked to hear her brother's words... "We can't... do this..." She tried again, very weakly. As Kate joined, she and Travis stepped a bit further away from the shower curtain, causing her to end up with her back against the cold wall. She shivered and bit her lip. "Please... Travis... I don't want this..." And yet her pussy seemed to be on fire.
