A few days and several hard fuckings later, Gwen needed a break. She and Joey had talked about doing something else, spending a day doing something normal, like they used to do. They’d been dodging their parents for weeks, constantly being asked if they wanted to go hiking on the trails that criss-crossed throughout the county. They both figured, with Todd’s permission of course, that it might be a good day to unwind and relax.
Since the incident with the Sheriff, Gwen had been on edge, waiting for the next surprise to sweep her up. She’d been fucked eight-ways to Sunday at that point, so much so that nightly sex with Joey had become almost routine. It wasn’t that she didn’t enjoy it, a lot of the times she did, but the constant need to be ready at the drop of a hat had become taxing. She wanted to recharge without looking behind every corner, every tree, and every rock, for Todd or his goons to pop-up and bend her over.
It was a warm, sunny day when the whole Tanner family loaded back into their car, the first time since they arrived, and headed out together. There was a ten-mile day hike their parents had been saving to do with their kids. It was a large loop through some smaller hills and valleys leading to a secluded waterfall. The length of the hike meant they’d be gone most of the day, returning shortly before dinner. That was great for Joey, because he had plans for the evening.
“I really don’t like you leaving tonight,” Gwen said while they were on the road to the trailhead.
“But I promised Rachel, I figured it was a good night because...” he stopped to think, “ ... you’ll be too tired to do anything else tonight.”
“Come on, Gwen.” Their mom said from the front seat. “You two hang out all the time, give him a night off for a date.”
What their mother didn’t realize and what Joey was attempting to subtly convey to his sister, was that she would be safe tonight. With Todd’s blessing, she wouldn’t be bothered and could stay at home in the safety of her room. Their parents would be close by too, if anything were to happen. There was a looming worry of Renny going rogue and not following his leader’s decree.
It was the perfect opportunity for him to make things up with Rachel, who he felt deserved a nice night out for once. He couldn’t even imagine the life she’s had, living with Todd as a brother; doing the things he constantly made her do. He also knew he hadn’t helped, using her too for his own selfish needs, although at the behest of Todd. He wanted to give her one night of her own, one to make her feel special, like a normal girl on a date.
“What have you kids been doing all summer anyway? We hardly see you.” Their dad asked, his eyes on the winding road ahead.
“Oh, nothing special,” Joey casually replied.
Gwen was next, “Yeah, going to the beach, meeting new people and laying around. Mostly trying to stay cool.”
Their dad laughed, “Yeah, it’s been a hot one, that’s for sure. I’m glad you two are making friends though. Didn’t I say this place was great?”
“Yeah Dad,” they both replied with a touch of sarcasm in their voices.
They pulled up to the trailhead around 9:00am. The small parking lot fit only four vehicles and two had already been taken. It likely wouldn’t be too busy on the trail, as the weather would climb into the low nineties with clear skies and little wind. They climbed out of the car, each carrying a small backpack with food, extra clothes, and lots of water.
For Gwen, it was the first time in weeks she got to wear proper underwear again. She’d been wearing her bikini almost every day and it was getting pretty gross. She’d rinse it regularly, trying to keep the cum and lube stains down, but never gave it a thorough washing. She soaked it in the sink overnight with soap and water and hung it up in the shower before they left. It felt great, the cotton rubbed up against her crotch snuggly and her bra supported her tits properly. She almost felt human again, and not the fucktoy she’d been forced to become. She even got to wear shorts for the first time in weeks.
For Joey, his thoughts drifted off to later that night and not necessarily of that moment. His torment had been more psychological than Gwen’s, being forced to watch his sister get fucked mercilessly. They were molding him, trying to turn him into one of Todd’s acolytes, and at times he could feel it working. He watched Gwen walk in front of him, her cute ass packaged inside a pair of hiking shorts. It made him want to pull her into the woods and rail her against a tree. She’d given him a blowjob that morning, before she snuck off to her own room to pretend she’s slept there, but he wanted more. If their parents weren’t there, he could ask, and she’d have to give it to him ... but he still felt that voice telling him not to, but that little voice became quieter every day.
“You’re going to love this spot; the water falls from twenty feet up...” their dad said happily, blissfully unaware of the internal battles being waged within his progeny.
“Yeah, Fred and Jillian showed us some pictures. It’s beautiful.” Their mom added. Their parents had made several friends in the area that they hung around with most days, and those friends had friends too. It was lucky, because it meant they were gone often, leaving Gwen and Joey on their own most days.
A few miles in, their parents were a short way ahead, having spent more time hiking around this summer. Joey and Gwen weren’t tired, but still lagged behind, taking things a bit slower. The spacing gave them freedom to talk openly, without hiding behind subtly and wordplay.
“How are you doi-” Joey was instantly cut off.
“I swear, ask me that again and I’ll tear your balls off,” Gwen snapped.
Joey raised his hands in surrender, “I meant with the hiking ... How are your legs doing?”
“Oh...” Gwen replied sheepishly, “ ... they’re good. Thanks for asking.”
“Defensive much? You’ve been short with me ever since the liquor store, what’d I do?”
Gwen shot around toward him and stuffed a finger painfully into his chest. Her eyes glowed with fire burning right into his.
“You sold me out. You sold me out to that gross old man!” she spat, doing her best to keep her voice down with their parents still close by.
Confused, Joey didn’t understand, “You were going to have to do it anyway, Todd was going to make you suck him off. How was it my fault?”
“You didn’t have to make suggestions, ‘why don’t you make her strip naked’” she said in a mocking tone. “You just made the whole thing worse.”
“YOU told me to make friends with Todd, that was your plan, remember?” replied Joey defensively. “I think I helped him there, and that helps us.”
“Using me! I’m not a thing, Joey.”
“To them you are,” Joey replied bluntly. “I hate to say it, but it’s true ... and you know that. Don’t think I don’t know you made some kind of deal with Todd, that day at the pond ... You’ve never told me about it or what it was...”
“I was desperate and it saved MY ass, literally,” Gwen fired back.
A voice from up the trail called out to them, it was their dad. “You two alright back there? We seemed to have lost you...”
“Yeah, are we going too fast?” Their mom called back.
They’d indeed lost sight of their parents, too wrapped up in their argument to notice them disappear around a bend. They stopped fighting for a moment and got back to walking.
“Sorry, we’re still here...” Joey called out, cupping his hand into a cone near his mouth. “We’ll catch up.”
“Don’t get lost!” Their father replied.
The two marched forward, both stewing from the other’s attacks. The pressures placed on them by the situation was slowly eroding a lifetime of memories. Their strong bond showed signs of fracturing under its weight. They needed each other to get through this, and each of them knew it.
“Look, I’m sorry,” Joey said first as they trudged along, kicking a small stone with his boot. “We shouldn’t be fighting; it doesn’t help us. I didn’t mean to make things worse for you; I was trying to do what you told me.”
Gwen gave an exasperated sigh, “I know, but it still pissed me off. Now that creep is going to fuck me next time Todd buys booze. And then the so-called Sheriff...”
“You heard Todd though, there’s nothing he wants from the sheriff worth your cost, you should be fine,” Joey replied.
Gwen went silent, there was still the thing she hadn’t told her brother yet. The favor owed. Todd could ask her to do anything, and she’d have to do it. Technically, she already had to, but this went beyond any of that. She hadn’t told Joey because she didn’t want him to worry; she already knew it was a calculated risk. It had been a solution to an immediate problem; a can kicked down the road.
“You never know with Todd.” Gwen chose to keep her deal a secret. “Anything could happen at any time; we show up to a party and next thing we know I’m tied to bed getting gangbanged. It’s why I don’t like you leaving tonight for some date.”
“So, this is what it’s actually about?!” said a frustrated Joey. “I’m going out on my own one time with Rachel; it isn’t a big deal. Not worth getting so jealous over.”
“I’m not jealous!”
“Sure seems it to me,” Joey fired back. “Have you ever thought maybe she could use a night out with a nice guy?”
“Pfft, yeah, when does she meet one?”
“What is that supposed to mean?”
Gwen looked away, “Nothing. Forget.”
“No, no, no, no...” Joey said, stopping her in her tracks. “You don’t get to say something like that and then say forget it. What did you mean by it?”
“I shouldn- I didn’t mean to say anything,” Gwen backpedaled.
“Oh no you don’t, out with it. Say what you need to say.”
Gwen inhaled and exhaled deeply, “Before we got here, before all this ... back at home, you were on the verge of being like Cas or Renny, you just didn’t have the self-confidence or support of a Todd.”
Joey’s mouth dropped in disbelief at what his sister had just accused him of being. Sure, he’d get a little overexcited on dates, having to be told ‘no’ more than once, but he wasn’t a blackmailing rapist or anything.
“Wow ... I can’t believe that’s how you think of me.” He said when he managed to get over the hurt of her comment.
Gwen decided to be honest, “It’s true though, think about it. Remember Tammy? She said you were like Spiderman, hands everywhere.”
“You never told me that.”
“I told you to give it a rest and relax, stop pestering her so much and let things go naturally. You didn’t, you kept pushing and pushing till she dumped you.”
“But it’s not like that anymore,” Joey argued. “I don’t need to pester Rachel for anything; if I wanted it, I could just tell her to do it.”
Gwen turned and gave him a knowing look. “Did you hear it right there? Did you hear yourself say what you just said?”
He had heard himself and he couldn’t believe it himself. “Th-that was Todd ... it’s his conditioning. I’m not like that...”
“You were like that Joey, or are you becoming Joe? Are you planning on screwing Rachel tonight?”
Joey shook his head, “I ... I hadn’t thought of it, maybe.”
“Exactly. I guess we’ll see when you get home,” Gwen said pointedly, cutting Joey deep.
She continued up the trail, but Joey remained in place. Her words poked and prodded his mind and jabbed at his heart. He felt a radiating fury building inside him, like his blood was gasoline and she’d thrown a match. Raising his hand above his head, he struck.
SNAP
Gwen turned around like she’d heard a gunshot. What she saw was equally chilling. Her brother’s eyes glowed with rage, and his hand was the source of the noise. She knew what it meant, and it sent shivers down her spine. She ran back toward him.
“Are you crazy, Mom and Dad are right down the trail.”
He acted like he hadn’t heard her, “Bitch. Shorts off.”
“Joey, no!” she protested, looking back up the trail to where her parents could pop up any moment.
His eyes snapped to hers, staring into them unblinking. Gwen knew at that moment he was serious and not playing around. It was scary, but also kind of arousing. She’d never seen her brother so forceful and confident before, it looked good on him.
“Where?” Gwen asked, now surprisingly obedient.
“There.” Joey pointed off the trail to a large tree. Gwen walked off into the brush, toward the large tree. She felt herself get excited at the danger of it all, not to mention her brother’s attitude change. Her panties were damp and not from sweat.
When they reached the designated spot, just hidden from view of the trail, Joey grabbed her and thrust her against the rough tree trunk. She could feel its grooves and knots in her back, as her brother loomed hungrily in front of her.
“Bitch. Shorts off.” He repeated. He almost sounded like Todd, a disturbingly similar emptiness in the tone of his voice.
Gwen undid the buttons on her shorts and pulled them down along with her panties. She stepped out of them, leaving her hiking boots on. Joey undid his shorts, and they fell around his ankles, his cock was as hard as ever. He pressed himself up against her, her back and ass on the tree and grabbed her ass and hip, lifting it around his waist.
He grabbed his cock and thrust it toward Gwen’s pussy. It pierced the thick hair and slid along her slippery slit. He shifted and thrust a few times but couldn’t seem to find the hole. Gwen shifted her pelvis to help him find the target; when he did, he plunged fully into her depths.
“OOOoooooohhhhhh” Gwen moaned as the air escaped her lungs. She couldn’t believe she was doing this with her parents only a few hundred yards away.
Joey didn’t care; he began to hump away, his rage and lust centered fully on his sister. It was taken by an animalistic need to fuck; to show her he wasn’t a joke. She put her hands around his neck and back, but he grabbed them away and held them above her head with his right hand. He looked into his sister’s eyes, glassy and lust-filled, and forcefully pressed his lips to hers, shoving his tongue into her mouth. She didn’t fight it; she wholeheartedly accepted it. When he pressed his left hand against her ass, she flattened her back against the tree trunk and lifted her other leg around his back. She was supported by the tree, her legs wrapped around him, and his cock in her pussy.
“Fuck me, Joey...” she moaned out as their lips parted. It was the hottest sex Gwen had had up to this point. It was pure need and lust; being taken by someone she loved so much.
They could hear the sound of their bodies colliding echo off the trees. The sloppy, wet sounds of Gwen’s juicy box pummeled by Joey’s stiff prick. Gwen was close, her back became raw from the bark. She struggled not to moan too loudly, in case her parents heard them, but it was difficult. She needed to cum and needed him to cum too.
“Cum in me, Joey ... I need it” she groaned in his ear.
“Am I still a joke?” he growled, his voice menacingly low.
“What?”
“Joey the cuck ... Joey the little bitch...”
Gwen didn’t know what he was talking about. He didn’t sound like himself, he sounded like a wild animal, baring his teeth at her. All she knew was that whatever he was doing, just made things even hotter. He was in complete control of her, fully dominant like Todd would have wanted, only it was emotional and not the controlling confidence of Todd. He was like a raging storm, slamming up against the shoal. Her brother, her rock, had become temporarily unstuck.
She tightened her legs around his back, gripped on for dear life as she endured and delighted in his onslaught. She couldn’t keep her moans down any longer and let out a series of low, guttural groans. Her body at the mercy of her normally calm loving brother turned wildly feral. At that moment, she didn’t care about anything else. All that mattered was where their bodies connected. Her brother buried deep inside her, furiously fucking her in the forest. They were as wild as the animals.
She came first and came hard, her trembling body sandwiched between a tree and her rock. She could barely breathe. Sweat dripped off her forehead, her back was soaked, and her pussy leaked down to the ground. She couldn’t take much more, she felt lightheaded like she might pass out.
“Please ... please...” she begged weakly, the muscles in her legs losing their grip.
“Who’s the bitch now ... who’s the fucking queer fuck ... Gggggrrrrroooowwwwwwww!”
Joey yowled like a coyote and slammed into her hard and held, pulled out partway, and slammed into her again without moving. Her ass was pinned against the tree. She knew he was cumming, she could feel it flowing through her, some going into her womb while the excess leaked from her ravaged cunt. It joined the wet puddle beneath them, a remnant of this wanton, illicit act.
As Joey softened, Gwen unwrapped her legs from around his waist and put her feet back on the ground. They wobbled, her muscles still weak. When he pulled out of her, more jizz poured on the ground while some ran down her inner thigh. She slumped to the ground and sat in the patch of wet dirt. Her brother hovered over her, his senses still hadn’t returned. He pressed his slimy, cum covered cock to her lips. She knew what he wanted, he didn’t have to ask. She parted her lips and let him sink past her teeth. She ran her tongue along the sticky underside and cleaned him dutifully.
She looked up at him, he looked down on her. She could see the fog of lust slowly lift from his eyes. The look on his face was a mix of confusion and horror as he realized what he’d done.
“Joey?! Gwen?!” They heard their mom call out from somewhere along the trail.
“Hey Mom ... be right there.” He choked out, pulling himself from his sister’s mouth with a slurp and a pop!
“Where’d you two go?” she asked from just out of sight. Joey didn’t dare peek around the tree to check.
“Uh ... bathroom.” He said quickly. “You know Gwen suffers from TB, tiny bladder.”
“Then why are you in there too?”
“She didn’t want to be off the trail alone. Afraid of animals or something, I’m giving her privacy.”
“OK,” their mom replied. “Remember, leaves of three let it be ... now, hurry up you two, we thought we heard something growling out here. Could be a bear... grrr.” Their mother said in a playful way, before turning and heading back up the trail.
