Family Tree by BangBear “So you’re fuckin’ Mrs. Coolidge now?” Alissa asked her brother. He chuckled, but he was embarrassed by her finding out. Especially with how she found them kissing in the car just now. “Yeah…” His sister laughed and walked towards the curb for a seat. “I should tell you my dreams so you can manifest those, too.” Trevor plopped down next to her, leaning back on his hands planted in the soft grass with his feet resting on his skateboard on the asphalt in front of him. “So? Spill it!” she said. “In the ass. A lot.” Her head snapped to look at him, eyes wide and brows upturned in shock at the scandal. The small curl of her mouth betrayed her increased interest in the gossip. “You’re lying!” “Have I ever lied to you?” “Yes! All the time!” “Ok, true, but this time I’m not, I swear,” he said with a smirk. She gave him a playful push. “Dude!” “And she called me back for more.” “Dude!” “AND, she just invited me to go on vacation with her and her friends.” “Oh, so you’re like married now. Like this is a honeymoon.” Trevor shrugged his shoulders. “Eeeeeh, I mean she’s still technically married, so not legally a honeymoon, but…” Alissa jumped up and contained her screaming to a loud squeal. “Dude you’re a bull now! Were there husband pics in the room? Did you like look at him while railing his wife in the butt?” “Look, I don’t really know the details!” he said, hands up by his shoulders with his palms to the sky to proclaim his innocence. “Fuck… fuck, Trevor…” “What?” “That’s like really hot.” She looked around the area, her eyes landing on a little spot next to the sidewalk that was covered by bushes and a shady tree. The girl bit her lip as she mulled over an idea in her head. “Hey, follow me.” Trevor watched his sister walk over to the vegetation, standing up and following her there shortly after. She waded through the leaves and branches to a small clearing, free from the view of the street and any of the windows from the nearby houses. She turned to see her brother pushing through the brush and she immediately got to her knees, her face right at crotch level with him. “Hey! You know we’re in public, right?!” “Relax, no one’s gonna see us here. Now lemme suck your dick.” He looked around nervously for a spot where they might be seen from. There weren’t many spots to be spotted from, but it was still a risk. The overhead coverage from the tree’s leaves blocked the second and third story windows, and the surrounding bushes covered the ground level. A keen eye might spot them, but they were relatively safe. At least enough for him to relax, his hand coming down on her head as he looked down at her. “Even after I told you where it’s been?” he teased. “You know where it’s going, right?” She pulled his shorts down and let his lengthening rod grow along her face, Alissa smiling up at him from behind it with one eye covered. “You want me to fuck your ass?” “I want you to fuck my ass.” Trevor leaned back against the tree and guided her mouth to his cock. “Well I don’t have any lube on me, so get to work.” She giggled up at him as she took him in, her hot, wet maw closing around him. She was sloppy with it, intentionally so. Her tongue lolled out and her lips remained open to hold him only loosely, and she didn’t stick with one angle or technique for very long before moving to the next. Twisting her head left and right around him, running through her muzzle sideways, giving her mouth a break and just tonguing him all over, all until he had a nice healthy sheen of drool on his cock. She was quick to get her jeans pulled down mid-thigh and turn herself around. Trevor did his part and got his tip lined up with her tailhole. “Relax yourself,” he guided, his hands on her hips. He could hear her take a breath and let her muscles loose. In time with this, Trevor pushed forward, his cock sliding through her ring and nestling snugly inside. In the same exhale, Alissa moaned from the uncomfortable pleasure of her brother being inside her forcing it from her lips. “Nnngh, fuck… I don’t use this backroad often enough.” “When I can get pregnant that way you can make it your main route,” she said, focusing on keeping herself loose as his thrusts started up slow. “We don’t know you can’t get pregnant here yet,” he joked, giving her a hearty spank. She tightened up for a moment. “You should let me do more experiments. Maybe dad can man the front while I do research.” “Ungh, stop I can only get so horny!” Her brother laughed and pushed deeper. “Dad and I fucked all night and all morning.” “And you still want more.” He ran his hand over her ass, pulling a cheek to the side to watch himself sliding in and out of his sister’s ass. “Nph, yeah… he teased me really hard at the end.” Trevor widened his stance a bit and sunk himself deeper, right to where his knot started to form. “Yeah? What did he do?” Alissa huffed out, her tail flapping once from one side to the other. “Hah, well, I asked if he could fuck me more like mom and, he, uhm…” She hesitated, turning her head to look at him with a smirk over her shoulder. “Spill it!” he demanded, spanking her playfully. “Ah! Haha, he pissed on me. In bed.” Trevor throbbed inside her, leaning forward more and shifting his hand placement on her hips for better leverage as he pumped away. “Yeah…?” She bit her lip and nodded back at him. “Yeah. He was done after that, but, ngh, then he choked me in the bathroom.” “Fuck, Liss…” “I almost came just from that. It was short but it was out of nowhere and he-glck!” Suddenly, her ability to speak was stolen from her, as well as her ability to simply move air into and out of her lungs. She tried to look back at Trevor, but his hand around her neck made it difficult. Trevor felt her trying this, and helped her to face him, looking into her eyes full of shock. She saw a look of hunger she’d scarcely recalled seeing before. Not for a long time, at least. And where the hell did this strength come from? Trevor was fit, sure, but he was lean skater. “Pregnancy cravings are already changing your tastes I guess.” He thrust deeper, pushing her down into the dirt with harder fucks. His feet shifted forwards, his center of gravity now forward from her hips and giving him even more leverage. Alissa tried to hold on to something, blades of grass ripping out from their roots and clumping between her fingers. Trevor hunched over and in low, and spoke right into her ear. “Once this litter’s out of you I’m knocking you up next.” Alissa’s eyes widened as she looked up at him, his hand still clenched too hard around her throat for her to respond with anything more than a stifled moan. Her stomach fluttered as a shudder ran through her, the girl’s tongue rolling out of her mouth as she quivered in orgasm. The clenching on her part made it tough for Trevor to slot his knot inside, so he had to settle for squeezing it with his free hand as his orgasm followed hers, unloading himself in his sister’s ass with a deep groan. He slumped down when he was through, forcing her her to bear his weight. She gasped for air, Trevor’s hand releasing her. Alissa nudged him off her by rolling into her side, her brother sliding out of her ass and resting in the grass behind her. As she refreshed her lungs, he propped himself up on an arm and checked in n her. “You okay?” Alissa nodded, the corners of her lips curling. “Did you really mean that?” she asked, turning to him. “I mean, once dad’s litter is out of you. It only seems fair, right?” She felt a warmth flush over her, and she giggled and turned to face her brother, pulling him into a hug and kissing his lips. “I think we could make that happen, but… I wanted to mention earlier, but we got a little side tracked. Dad isn’t the one that got me pregnant.” “Huh?” She nodded. “Yeah, I’m for sure pregnant, but all three of those tests were negative.” “So who…?” He froze mid thought, mouth dropping open. “No FUCKING way!” His sister shrugged. “I don’t know for sure yet!” “Dude that’s not even possible! I think?!” “I know! But like, what’s the other possibility?” “Immaculate conception?!” Alissa burst out laughing in the shaded vegetation they hid away in and shook her head. “Well, I’m gonna go to Sophie’s and get DNA samples for a test kit anyway. You wanna come with?” Trevor shook his head. “Nah, as much as I wanna watch you get fucked by a dog again, I need a nap.” He pondered for a moment, then spoke up again as Alissa started to pull her pants up again. “Wait, hold up a minute.” “What’s up?” She paused, her jeans scooping up under her butt. “C’mere…” Trevor got himself up and pulled her back towards the tree with him, resting her back against it. He helped her get her jeans completely off, leaving her bottomless. He did the same, and while still squat low, he gestured to his shoulders, instructing her to get her legs on him. “Another round? What happened to that nap you needed?” “Hngh, not quite,” he said, grunting himself back up to standing with her pinned against the tree. She chuckled, finding herself in this position for the second time that day. “Y’know, dad had me like this not too long ago…” “Did he still think it was his at the time?” She nodded with a smile and he stepped forward for another kiss, his tongue feeling the piercing on hers. His softening member pressed against her ass once again, still just firm enough to find its way inside, and getting a little moan from her. Aside from an instinctive thrust in deep, he didn’t move much, and she wondered what he was up to. They held like that for a few moments, the bark starting to hurt her back. “This is getting uncomfortable,” she said, breaking the kiss. “What are you-: “Just one more second…” Her patience grew thin, but she waited. Just a moment later, she heard him sigh, and a fresh warmth flooded her. “You’re...?!” “Hah, fuck… yeah,” he sighed with deep satisfaction. Alissa was disgusted. She should punch him. Kick him off of her and use his shirt to dry herself. What right did he have to piss in her without asking? And why was it so... fucking... hot? She grabbed the back of his head and pulled him in again, forcing hr tongue into his mouth and holding him tight against her. “Bastard…” she insulted though the briefest of breaks in their kiss. In the perverted passion, Alissa overstepped some boundaries herself. “Ngh, here’s payback, fucker…” was all the warning he got before a second hot stream joined in. He couldn’t help but laugh as his sister’s piss ran warm down his legs. “Bitch,” he jabbed back between smooches. His stream faded soon, and so did his vigor, his shaft falling out of her and letting his piss and cum drain from her ass and soak into the dirt below. “It’s gonna be fun getting knocked up by you.”
