Alex laid back in the cool flowing water of the alpine stream, feeling it cascade over his chest and into his lap. His undersized speedo pulled tight around his package and both girls dropped their gaze and watched as it grew, pushing out against his constricting his suit and sending the clear outline of his veiny shaft and ridged tip in their direction.
“My god,” Sam said under her breath.
“He does have a…” Lily started.
“Nice cock,” Sam finished for her. Both girls broke out in laughter, breasts and bottoms jiggling in delight.
Lily moved to sit at Alex’s side and crouched down. Sam tread carefully around his other side and squeezed into the cold stream opposite his sister. Both girls reached out a hand and took hold of his bulge, Sam cupping his balls between his thighs and Lily brushing her palm along his length.
“I can’t believe you two are together now,” Sam said, looking at the attractive siblings. Alex just grinned, still lounging restfully in the mountain stream and enjoying the attention.
Lily blushed and looked up at Sam. “He’s helping me get better. I guess this is what I needed to do that,” she said, giving him a tight squeeze. “I’m just sad it took me so long to figure it out,” she added and sighed, looking down longingly at his engorged speedo.
“It was Carrie’s fault,” Alex said. He thought about that fateful night on the couch during Lily’s birthday party and added, “And yours, Sam. And Fiona, and Becky, and Lynn, and Natalie, and Casey, and Megan, and…”
“Ok, we get it you horn dog,” Sam said, cutting him off. “You seem to have built yourself quite the harem in the past couple of weeks.”
Harem, Alex thought as he shrugged in response to Sam’s observation. He liked that word, it fit. But it certainly wasn’t intentional, his goal wasn’t to collect women, just their panties.
“What about Jenny?” Lily asked. “Does she know about all this?”
“She knows enough, at least about Casey and her friends. I haven’t mentioned you two, but I will if she asks or if you want me to.”
“And she’s fine with it? She’s your girlfriend, right?” his sister asked.
Alex nodded. “It’s weird, but yes, she said she was fine. For now, at least. I told her I wanted to be open about everything and she could ask me anything she wanted and I’d be honest. We’re going to spend a couple days alone next week, I’m taking her up to the cabin on Jenning’s Peak. I imagine we’ll talk more then.”
Lily smiled, she remembered the cabin fondly. The last time they were there as a family their father was still alive. She was surprised the memory didn’t cause her pain. Having Alex close seemed to make it okay; to make the memory good, rather than sad. There was still a small twinge of heartache, but not enough to swing her mood.
“Well, I guess you might be the luckiest man alive then,” Sam said, breaking Lily from her introspection.
“You won’t hear me complain,” he said with an impish grin as both girls continued to fondle him through his threadbare briefs.
“Go on and claim your prize, Sam. You won, afterall,” Lily said with a sigh.
“Nah, I’m good,” she said. “I think I’d rather watch. It’s not every day you get to see a brother and sister go at it.” Lily smiled at her friend and Sam stood, repositioning to sit on a nearby boulder.
“We’re not alone, you know,” Alex said, interpreting their overt intentions. Both girls glanced over their shoulders at the newcomers. They were about two hundred yards away, and still absorbed in setting up the camp. It wasn’t likely they had a clear line of sight through the boulder-strewn creek bed.
“They can’t see anything,” Lily said. “And even if they can, I don’t care.”
“That a girl,” Sam said encouragingly.
To illustrate her fearlessness, Lily stood and stepped over her brother, then reached behind her neck and pulled a string. Her top fell and her two proud breasts burst into the sunlight. Alex admired the dramatic jutting curves of her gravity-defying peaks as she spun her top around her waist and untied the final set of straps. She tossed the garment to Sam who snatched out of the air and stared in admiration at her beautiful friend. Lily reached up and cupped her soft mounds; pliable flesh spilled from her grasp as she pushed her perfect tits together. She dropped her hands, sending her breasts rebounding in tight swaying arcs. Once her thick pointed nipples came to rest, she squatted down onto Alex’s thigh and tucked her fingers under the waistband of his white speedo briefs.
Alex lifted his hips and let Lily undress him. She pulled his swimsuit down, stopping once his cock bobbed free and pointed skyward. Sam sighed atop her perch and muttered, “Yep, still not tired of it.”
Alex chuckled as Lily bent forward and wrapped a hand around his shaft. “Have you tasted this?” she asked her friend.
“Come to think of it, I have not. You?”
Lily shook her head. “There’s plenty to go around,” she said breathlessly as she opened her mouth and guided him into her warm wet embrace. Alex moaned as her lips wrapped around his ridged tip and her tongue rolled in lazy circles around his tender knob. Sam flew from her perch and joined her friend, straddling his knee and bending down. She kissed Lily’s cheek as if to thank her for sharing, and then dropped down, wrapping her lips around Alex’s shaft and sliding her tongue along his length.
Lily’s cheeks bent concave as she sucked with surprising force, her tongue flailing against his soft domed tip as her head bobbed in time with Sam’s movements. Alex wasn’t entirely to surprised to find his sister skilled in oral pleasure, but it was also not something he’d ever spent much time considering.
“Oh god, Lil, that feels amazing,” he said as her tongue twirled and lips pulled blood to his tip, swelling it further and raising it’s sensitivity by orders of magnitude.
Lily let his purple knob loose with a practiced pop and smiled up at him. Sam also raised her face and grinned, saying, “Her tongue is quite gifted.”
Alex closed his eyes and groaned as the two girls returned to their ministrations. Heads tilted, one to a side, they surrounded his cock, tongues and lips touching as they shared his thickness, each finding a mouthful to call their own. Up and down the two experienced young women traveled, entwined around his rigid girth. He felt himself quicken and groaned, raising his hips from the frigid waters in which he lay.
Lily broke rhythm when she felt his change and lifted up, enveloping his cock in her steamy mouth. The second she clamped back around his tender tip he cried out and throbbed into her throat, sending a heavy stream of cum splashing into her tongue. She moaned, rattling his sensitive head as a second spurt gushed into her mouth, coating her cheeks.
Lily let him free and gave him over to Sam, but their handoff was too slow and a rope of white liquid flew from his pulsating cock and splashed against the brunette’s face, dribbling down her nose and over her mouth. Sam stopped, licking her lips and tasting his seed as another burst arced onto her chin, dangling under her shocked visage. Gasping in indignation, she opened her jaw and sealed his surging shaft, swallowing his next pair of creamy outbursts.
Sam let him go and the girls each wrapped a hand around his pulsating shaft, marveling as he continued to spasm and pour cum from his slit, dribbling down until it covered the backs of their hands.
“Look at him go!” Sam exclaimed as his cock jumped and twitched in her gasp.
Alex finally settled and Lily lifted her hand, lapping his salty spunk from her skin. Sam did the same, purring as she cleaned herself like a cat. He felt his fires wane and consciously harnessed his gift, tending the flame to keep himself ready. It came as second nature, his companions were yet unfulfilled and he could sense their desire, especially his sister’s.
“It appears our boy hasn’t given us his all,” Sam said astutely. She clambered back atop her rocky perch and nodded down at Lily, flashing her a suggestive smirk.
Lily rose up and stood next to Alex. Reaching to her hip she untied her pink and purple bikini bottoms and let them slide down her leg and into the creek. Alex looked up at her naked body, watching her hips sway as she stepped over his lap. Focusing on the treasure between her thighs, he followed it down, seeing her spread and expose her thin wavy folds as she lowered herself onto him. She reached down and spread herself with one hand, while guiding his towering cock with the other. The siblings came together and moaned in ecstasy, Alex filling his sister, their shapes fitting perfectly together as if their union was meant to be.
“Fuck,” Sam blurted. Alex looked over at the brunette. She sat atop a large rock, legs open with a hand between her thighs. She’d pulled her bikini to the side and was sliding a thin finger into her pink crease, flitting aimlessly over her clit while watching Lily mount her brother.
Lily’s need for release quickly overcame her desire to prolong their mating. She bounced enthusiastically on Alex’s lap, sending her hefty pert breasts dancing before his eyes. Her narrow lips gripped his cock with increasing tightness as she clenched and pulled against his shaft each time she rose from his lap. Breathing in heaving gasps, Lily drove her body down and lifted up as cool water splashed and weather-smoothed rocks knocked and ground together under the weight of their shifting bodies.
Alex looked back over at Sam, catching a flurry of movement from the corner of his eye. She had two hands between her legs now, one holding her bikini to the side and the second waving furiously over her pussy, sending her swollen folds shaking in circles. She groaned and slipped two fingers inside her pink tunnel, biting her lip as she made eye contact with Alex.
Lily bent down, resting her palms on his shoulders, and playfully bit his earlobe. Alex yelped and turned his gaze back to his sister, smiling in embarrassment as she commanded his attention. He focused on her tight wet grasp, looking down as she leaned back up, balancing with her hands on her knees, legs splayed wide giving him a perfect view of his penetration. His glistening cock vanished inside his sister’s perfect taut pussy, visibly distending her narrow belly as his girth filled her to the brim and moved her insides. She moaned while lifting back up and Alex watched as her thin lips gripped him and extended, following his length until Lily expertly stopped and left them kissing his tip, his ridged crown just visible between their wet grasp.
