"Come on, loser," Vanessa whined over her shoulder, "we've got to get away from the main trail." She stopped to catch her breath, suddenly conscious of how warm the day had gotten, and aware of how much she was sweating.
She didn't hear Gavin's footsteps, so she turned around to see him staring up at her from lower down on the trail, a happy expression on his face. Probably because he had been staring up her skirt.
"I don't see why we have to go so far off the beaten path," he called up to her, his voice cracking a bit, "this place seems as beautiful as any."
"You know why, dumbass," Vanessa called back, "now come on."
He didn't move. "Am I going to get what I want this time?" he asked, a hint of annoyance in his voice.
Ugh, Vanessa thought to herself, he can't just do what he's told and give me a good time.
"Sure," she called down to him, "if you do a good job."
That seemed good enough for Gavin, and he started up the trail, carefully picking his way across spots where seasonal creeks had washed away most of the dirt, and following the path Vanessa had climbed up the rocky hillside. He was shorter than her, and two years younger, but he seemed to be growing fast enough that the two of them would likely see eye to eye by December. For now, though Vanessa was taller, stronger, and trusted to 'look after' Gavin while their parents kicked them out of the house, the hotel room, the Air B&B...their family traveled a lot, and Vanessa had learned what sex was by returning back from an enforced exploration to find her parents in the middle of it. The pair seemed to be on a quest to fuck in as many places as they could before they died, and having kids to take care of wasn't going to get in their way.
At least they liked having sex with each other. And more importantly, they trusted Vanessa to wander around hiking trails, luxury resorts, cruise ships, the local neighborhood, and wherever else the family ended up, armed with a can of pepper spray and the knowledge that Gavin would do whatever she told him to.
Today, like most days on their family trips, Vanessa was horny. Today, unlike most days on their family trips, they were staying somewhere deserted and remote enough that she could do something about it.
Well, it was more accurate to say that Gavin was going to do something about it, when Vanessa ordered him to.
Gavin finally made his way to Vanessa, and he looked around the level clearing they were in. It wasn't quite off the trail, but the grass growing thick on the dirt path made it seem, to Vanessa at least, like this part was far less traveled. Gavin unbuttoned his shorts, and began to unzip them.
"What the heck are you doing?" Vanessa hissed at him, stepping up next to him and looking around anxiously.
"You're taking care of me first this time," Gavin answered, finishing unzipping his shorts and tugging the waist of his boxers downward.
"And why would I do that?" she shot back, only half-alert to their surroundings now that her little brother's bulge was visible. He really did have a good dick, whenever she made him bang her with it.
"Because," he countered, trying to keep his voice low, "the last two or three times you said that you would help me as well, you had your fun and then said we were done. That's not going to happen today." He finished pushing down his waistband and his dick sprang free, and he tucked the elastic down under his balls.
"Ugh," she said, reaching for his penis, "fine." She took hold of it, and began to stroke it roughly. He winced, and pulled away.
"What the heck Vanessa," he whined, "that hurts!"
"Do you want me to jerk you off or not?" she snapped at him.
"I want-" he stammered, "I want you to use lube at least! You don't want me shoving it in your vagina dry, so why would I want you to jerk it dry?"
"Jeez, you're so freaking whiny," she complained, "but fine. Have it your way." She spat in her palm a few times, and once more grabbed Gavins dick, stroking him a few times so they could both hear the wet squelching sounds. "Better?"
"I guess," he said, "I was kinda hoping you would put it in your mouth again."
"No," she drawled, jerking Gavin's dick and remembering the last time she had let him convince her to suck his dick. He had jizzed in her mouth without warning her, and she had spit it all over his jeans in response. "You would have to do a lot for me to earn the right to get your dick sucked again, you little jerk," she said, looking around at the dirt, rocks, and plants, "way more than we could do here."
"Like what?" he asked, still insisting even while she was being such a fair older sister and jerking him off.
"I don't know," she replied, pulling her hand away to spit in it again before going back to jerking him off, "I would get to peg you or something."
"Not freaking happening" he replied angrily, even as his breath was becoming labored, "you're not sticking anything else in my ass."
"You came super hard, though," Vanessa countered, grabbing his balls with her free hand and squeezing.
"I said no," he replied, "and stah-stop squeezing so h-hard. It--mmph--hurts."
"Guess you're not getting your dick sucked then," Vanessa replied, releasing his balls, and stopping stroking him long enough to spit into her hand again. "Are you getting close? I think someone else is coming down the main trail."
"I would be, if you didn't keep sto- oh. Oh just like that Vanessa, please let me come."
Vanessa had hacked up a gob of spit into her hand and gripped his cock hard, and was furiously jerking him as fast as she could. She really did see someone coming down the main trail.
Whoever it was, the passed by almost a hundred feet away and down a rocky hillside, cut off from seeing Gavin and Vanessa by a couple of trees and shrubs. Even so, Vanessa covered Gavin's mouth to stop him from moaning as he began to buck against her hand, and she pulled her hand away just as he started to come.
Gavin shot two spurts of jizz onto the ground below, the sticky fluid sitting on top of the dry dirt where it landed, before he managed to grab his cock with his own hand and continue jerking himself off. He glared at Vanessa as he finished, her left hand still clamped over his mouth. After a few more shots of semen, he stopped jerking himself furiously and settled into a slow massage of his length.
"There," Vanessa said as she let go of his mouth, "happy?"
"No," he replied, still glaring.
"Too bad, loser," she responded, putting her hands on his shoulders and pushing down, "on your knees. My turn."
He resisted her push, shifting a couple of steps to her left before obediently dropping to his knees. Vanessa almost questioned him, only to realize that she had been urging him to kneel down in the puddles of his own come.
"I got you off, so you better do a good job," she said, stepping up to him and flipping up the front of her skirt, "and no complaining." She grabbed the top of Gavin's head and roughly shoved his face into her crotch, savoring the stifled groan he gave out as he was forced to breathe in the scent of her sweat and arousal. "Shut up and lick it," she grumbled, "you know you love it."
Gavin finally stopped resisting her pull, and she thrust her hips upwards to drag her crotch across his face, savoring the feeling of his breath washing across her folds through damp panties. This skirt didn't have a liner, which is why she had chosen it, but she wasn't dumb enough to go completely commando.
In fact, the fact that she could make Gavin lick her through her panties was even better, in a way. It would really make him work for it. She ground her hips forward, feeling the outline of his nose and lips as her own folds were pushed into them through the quickly dampening fabric. She felt a pressure, and an extra wetness, evidence of Gavin obediently pushing out his tongue to try and lick her. It only felt like the tip, though.
"More, dipshit," she growled, and then sighed as she obediently felt a wide wet pressure push through the panties into her cameltoe, the sensation of Gavin sticking his tongue out as far as he could so that she could ride it. She did so, grinding down into him and savoring the way he tried to push his tongue up into her, the folds of her panties pushed in between her own damp folds. Gavin tried wiggling his tongue back and forth, but with the panties pressed between his face and her crotch, there wasn't enough give to allow him any more than an insistent pressure.
"Good boy," Vanessa chided mockingly, "you like sucking your big sister's vagina, don't you?"
Gavin gave a groan in response, albeit one that was far more engaged and horny than his previous protests. Their sexual adventures had begun when Vanessa had caught Gavin peeking through the bathroom door in a cruise ship room the two had been asked to share, while their parents commandeered the other room for a midday screwing. Vanessa had looked around the translucent shower curtain to see Gavin masturbating while looking in at her, a reveal made less embarrassing for him since she herself had been masturbating in the shower. That day, she had made him lick her to orgasm, while he jerked himself off, and their dynamic had been set in stone. Vanessa got what she wanted, and if Gavin was lucky she helped him orgasm too.
In the present time in the woods, Vanessa began to move her hips back and forth, grinding herself against Gavin's face.
"Open up," she ordered, "suck on my pussy while I ride you."
She felt his jaw open, and he even made a cute little "aahhh" sound as she shifted around, trying to find the right angle.
"There," she said after a moment, "suck."
Gavin obediently began to suck, pulling most of her vulva, her panties, her labia, and some of her pubic mound into his mouth while he sucked hard with a wide mouth in a spot roughly centered on her clitoris. It wasn't a perfect seal, and Gavin made wet sucking sounds that sounded remarkably like the gagging of women giving deepthroat in some of the pornos Vanessa had seen.
"Yeah, just like that," she said, her voice coming out more sultry than she expected, "use your tongue, too."
Gavin's tongue tapped and pressed at the center of where he sucked her, close to her clitoris, which she could feel had grown so hard that the brush of her damp panties across it sent shivers up Vanessa's spine. She became suddenly aware of her clit, aimed at the back of Gavin's open mouth, and her thoughts returned to the deepthroat videos.
"Yeah," she said, pushing her hips against him, slowly humping his face without breaking his suckling grip on her, "take it. Take it good...bitch."
Repeating the words from the videos caused a simmering pleasure to pulse through her, and she realized that her normal enjoyment was somehow accelerated by...whatever this was. She humped Gavin's face again, hearing him suckle and groan as he tried to do what she asked while she bucked. It was incredible. She did it again. And again.
Pretty soon, she was in a rhythm, humping Gavin's face through her panties, feeling the fabric sliding over her clit while Gavin tried in vain to consistently tease it with his tongue. She was moaning now, and the simmering inside of her had begun to boil. Her fingers clenched and flexed against Gavin's head, and her breathing was heavy. Something white-hot was flickering in her chest, something she hadn't felt more than once or twice in all of the times she had come before, with Gavin or on her own. Her face felt hot, and her feet felt numb, and all sensation seemed to gather in her nub.
She humped Gavin's face hard, feeling the sensation of her clit passing his lips, pulling out, and being slammed back in. It didn't take up notable space, but in her growing haze she imagined it did. She listened to the sound of Gavin struggling to suck on her vulva, and imagined how he would sound gagging on her dick. She pictured her clitoris growing, swelling, getting thicker and harder. Her legs began to get weak and her thrusts became uneven as she pictured it growing to at least twice the size of Gavin's dick, big enough to choke him and make him cry.
"Oh, oh fuck," she moaned, her entire body awkwardly flailing as she tried to keep thrusting, "take it slut. Take it."
Gavin took it. He sucked at her, practically biting on a wide mouthful to hold on against her erratic thrusting. She knew that if she did have a dick, he would have taken that with gusto as well, and it was this thought that detonated the orgasm in her.
Heat.
Fire.
Her clit--her cock--shoved into Gavin's obedient mouth.
Her fingers were flexing. She pushed forward, forcing her weight onto Gavin as her legs buckled. She was aware that her head was lolling loosely atop her shoulders, and that she was moaning and shaking as she kept fucking Gavin's face.
She was blind. Or closing her eyes. Or maybe her eyes were burned away.
She felt it subside, remembered for a moment who she was, and then Gavin mumbled around her and it started all over again.
She felt a tightness near her entrance, but above it, and squealed as she tried to hold it. She couldn't, and she felt a wash of warmth spill into her already-soaked panties, causing Gavin to groan in surprise.
"Shut up," she said, holding him close while he tried to pull away, "shut up and--mmph--take it. Take it all, bitch."
She felt Gavin go weak, and fall backwards away from her. She was too weak herself to hold him, and he stumbled onto the ground, catching himself with his hands before sliding down to lay on his back. Vanessa quickly reached up under her skirt, her fingers searching for--and finding--the waistband of her panties. She pulled them down, and pulled one leg out with a wobbling step.
"Vanessa," Gavin whimpered, "when you came, did you pee on m-mmph!"
His question was cut off as she spun around and promptly sat on his face, facing his feet and grinding both of her exposed holes onto his face. He tried complaining and yelling underneath her smothering crotch, but all it served to do was run his lips and tongue across her now-exposed labia. She felt another orgasm building in the aftermath of the previous two. She bounced her hips up and down on Gavin's face, feeling his nose pressing against her butthole. He began to cry.
"Oh stop," she said, looking down, "you know you love it. Look," she continued, reaching out and grabbing his semi-hard penis, "you're even hard about it."
Gavin's crying quieted down, and soon he was obediently licking and sucking at Vanessa's pussy while she sat on his face. His cock grew harder, and she felt a pang of jealousy.
Why does Gavin get to be the one with a dick, she thought to herself, when I would do so much more with it than he ever could?
The thought carried her until she realized another tingling was building in her fingertips, washing through her as a pleasant, sense-softening warmth in contrast to the explosion of her first orgasm. When it reached her core, her breath shuddered and she had to put her hands the ground to stay upright as her body shook. Eventually, it faded, Gavin's efforts no longer sufficient to keep her coming. Still, she remained sitting on his face, thinking about what she had fantasized about right before her release.
"The Tuesday after we get home," she said, lifting her hips to allow Gavin to breathe and hear her clearly. She waited a moment to allow his heaving breaths to calm enough to where she knew he was listening. "Yeah, the first Tuesday after we get back, when Mom and Dad go on date night? I'm pegging you."
Gavin stammered, about to protest.
"No," she said, "you don't get to say no anymore. I'll even suck you off, but it's happening. Now thank me for fucking your face."
"Thank you for fucking my face," he said, audibly trying not to cry, "can we be done now?"
"...nah," she responded, settling back down onto his face, "it's a nice day, I want to stay here for a while."
Gavin, like any good brother, didn't argue as she smothered him once more, his cock twitching slightly.
