Tryouts
Alex woke to his alarm clock blaring. He smacked it blindly and bought himself ten more minutes. Grumbling, he sat up. It was ten past eight and lifeguard tryouts started at nine. A mix of anxiety and nerves turned his stomach as he considered what the experience would bring. The only information he had was gained during a short phone call days ago. He knew to expect a written test and a swimming skills evaluation, and there would be at least three other people competing for the same job.
Rising from his bed, Alex pulled on a pair of boxers and t-shirt and walked to his bathroom. After a quick shower, he dressed in a pair of jeans and a button-down shirt. He packed a small bag with his competition swimsuit, goggles, and a towel; everything he thought he'd need for the swimming part of the tryouts. As he left his room, Alex heard moaning coming through his sister's door. It seemed that Casey and Megan were still playing with the toys he'd given them the night before. He smiled and checked his phone for the time; ten minutes to spare, long enough for a little fun.
Quietly turning the handle to Casey's room, Alex peeked in to find Megan kneeling behind Casey, naked except for a pair of belts circling her waist and narrow hips. His sister was on her knees and elbows, moaning loudly while her friend pummeled her with a big black strapon. Alex stood with his jaw gaping open at the sight, the smell of feminine sex and sweat were heavy in the stale air. He watched Casey flail wildly on the bed with Megan knelt behind her, thrusting in an untrained but clearly effective rhythm. Alex undid his zipper and pulled out his cock, twirling his fingertips over his sensitive tip and feeling himself grow. He stroked himself to potential while watching Megan, harnessed in and eagerly plowing the thick black toy into her friend.
"I see you like my gift," he said, stepping into the room and smiling with his dick in hand. Megan jumped and Casey yelped as the heavy dildo popped out of her unexpectedly. "Don't stop on my account," he said, and then walked around to face his sister whose head was near the foot of the bed. She smiled at his wagging cock, licking her lips, and then opened her mouth in anticipation. Alex stepped closer and placed his tip on her outstretched tongue. He angled his hips, sliding his sensitive glans around her mouth while she licked across his rippling skin and flicked her tongue along his tiny slit. He thrust forward and his sister closed her lips, circling his thickness and sucking with gleeful abandon.
Alex looked up at Megan and she grinned wickedly. Grasping the black dildo hanging between her legs, she aimed at Casey's entrance and thrust back inside her. Alex felt vibrations rattle through his body from his tip to his core as Casey moaned from deep in her throat. Megan wasted no time picking up where she left off, railing into her petite friend, clearly excited to have her very own boy parts. Her small breasts careened recklessly as each thrust bounced Casey forward and his cock slipped farther into her mouth. She rebounded, pressing against the massive rubber cock that unnaturally dangled between her friend's thighs, and he slid back out of her tepid mouth.
Alex stood motionless while Megan fucked Casey's mouth along his cock. It was sensational, a blowjob by proxy. He heard wet slurping sounds coming from both ends of his sister as she had two holes filled at once. The debauchery of the scene quickly caused his climax to rise. Casey was also close, her hips began to buck and her breath quickened, sending gasps of hot air through his short hairs. The siblings groaned in unison and Alex's cock twitched, spurting a hot stream into his sister's trembling mouth. He slipped out of her as she collapsed and buried her head into a pillow to suppress a deafening scream. With nowhere else to send his spunk, he aimed down her back, sending one long milky thread along her spine before dribbling the rest onto her bed sheets.
"Mine!" Megan said excitedly, quickly unlatching the strapon and crawling up Casey's body to claim Alex's gift. She noisily sucked up his mess, Casey squirming and giggling beneath her.
"Stop, that tickles!" she gasped while Alex chuckled and tucked himself back into his pants.
"Unfortunately, that's all I have time for this morning," he said and leaned down to kiss Casey's pink cheek before turning to leave.
"Wait!" she said, and crawled out from under Megan with urgency, meeting him at the door. She threw her arms around his neck and pulled him down for a long kiss. "Good luck today, I know you'll do well," she said and smiled at him lovingly.
"Thanks. Try to leave your bed at some point today," he said with a teasing smirk.
"If she'll let me go..." Casey said, trailing off in reference to her randy friend.
Alex laughed and then left the room, climbing downstairs where he quickly fixed himself a plate of eggs and toast. He ate outside on the patio, enjoying the warm summer morning. He tried his best to not become distracted by Casey and Megan and everything else that had transpired the past weekend, instead, he attempted to mentally psych himself up for the day's events. He wasn't worried about the swimming evaluation, that should be no problem given his training regimen. He just hoped he would be able to impress during that portion of the tryouts to cover any mistakes he may make on the written test. Finished his meal and deciding it wasn't worth worrying about what may or may not be, he stood and walked back inside the house.
In the kitchen, Alex was greeted by a pair of familiar disheveled faces; flush, eyes glossy, and hair a mess. They must have kept going after he left. Each wore a tank top and cotton panties, neither had a bra on. He counted four peaked nipples pointing in his direction as the couple turned towards him. "Hello again, beautifuls," he said cheerily. "Did either of you manage to sleep last night?"
Megan giggled and Casey said, "I think so. I'm not really sure, it was such a blur." She was still in a daze from everything that had happened the past two nights.
"Thanks for the toys," Megan said as she walked up and kissed him lightly on the lips. "You should see what else your sister can do," she purred in his ear.
Alex backed away and said, "Glad you enjoyed yourselves. Don't forget to see Jenny today, she's excited to have both of you start work. And Lily should be home this afternoon, it would be nice if you could manage to clean up from the party a little bit and maybe put some pants on."
"Listen to mister all work and no play over here," Megan said, turning to her friend.
"He's right, we should pick up. The party's officially over," Casey said, sighing with a gloomy look on her face.
Alex walked up to his sister and gave her a hug, then he pulled back and kissed her softly on her forehead. "Thanks, sweetness. Think of something we can do together next weekend. Maybe we can take a trip somewhere?"
Casey immediately brightened at the suggestion. "Ok, I'll come up with some ideas. And thanks again for the amazing party. I'll never forget it," she said and then wrapped her arms around his neck and pulled him down for another kiss.
