Rob leaned back heavily in the lounge chair reveling in the dual sensations of the blowjob he just gave to his best friend, Mark, as well as the one he just received from his best friend's sister, Marissa.
Rob tried to act nonchalant as Marissa curled up next to him on the poolside lounge chair and Mark flopped down in the one next to them.
"I take it that this is not the first time you guys have fooled around?" Rob asked
"Today or ever?" Mark responded with a smirk. "That was just a stress reliever for you so you'd stop being such a prude."
"No, Robby, it's not," said Marissa smoothly as she languidly caressed Rob's chest with one hand and idly stroked her glistening pussy with the other, "In fact, Mark, why don't you tell him how this all started?"
"Sure thing, eh." Mark put his hands behind his head and basked in the warm afternoon sun. "Remember, Rob, how I was late to your 18th birthday party? Well..."
MARK AND MARISSA'S STORY
Mark arrived home from school early having ducked out of baseball conditioning practice complaining of a sore shoulder. He tossed his backpack on the couch and kicked off his shoes heading straight for the back patio and the waiting pool and south Florida sun. He stripped off his shirt and dropped his shorts and boxers in a puddle around his ankles allowing the warm breeze to caress his body. He dove into the refreshing pool and swam the length underwater, pulled himself out the side and headed for the lounge chair sitting in the full sun. He grabbed up a tube of suntan lotion, shot a liberal amount onto his hand and began massaging it into his skin.
As was his after-school custom, he lay back on the lounge chair, squirted another daub of lotion into his hand and set to work on his cock. Closing his eyes and reveled in the feeling of his manhood thickening at his touch. Once fully erect, he slowed his ministrations to a more reasonable pace wanting to enjoy the building sensation that would ultimately lead to a happy ending.
Marissa drifted down the steps from her upstairs bedroom being rudely awakened from her nap by the clatter of her younger brother's exuberant arrival, albeit an hour early, from school. Her classes at the university were cancelled for today so she spent the late afternoon relaxing and sleeping.
She followed the trail of school gear and clothing leading out to the pool where she spied her brother blissfully stroking his massive cock. Her breath caught as she took in the sight of her toned and muscled brother, eyes shut to the world, working his thick member with his hands. A chill ran down her back and directly to her, as of this morning, freshly shaven pussy. Involuntarily, her hand drifted to the terminus of that jolt and she felt warm moisture at her fingertips.
As quiet as she could manage, she slipped through the patio door and padded silently to where Mark was lounging, all the while lightly stroking her now engorged clit. She had never seen her brother naked before and was in awe of what she saw, especially the hard, thick cock he was slowly jacking not five feet from where she stood. She knew he sunbathed nude, she did too, so did mom and dad but this was different, somehow. A slightly stronger stroke to her needy clit elicited a gentle moan, unbidden, from her lips.
Mark's eyes shot open to see his sister standing at the end of his lounge chair, her eyes fixed on his cock and her hand at her crotch.
"I didn't know you were home." Mark said. He tried to stand but Marissa stopped him with a hand on his shoulder, the same far-away look in her eyes. Mark sat back on the lounge chair and it was then he looked at Marissa, appraising her for the first time. He had seen her nude before, sunbathing by the pool but never this close. Her long brunette hair rested neatly on her shoulders framing a face that artists yearn to recreate. Her moist lips parted slightly and her brown eyes stayed transfixed on his still-erect cock. Her beautiful breasts were capped by dark nipples, hard and erect in her excitement. Mark scanned down her toned, flat abs to see a sight he was not expecting, her shaved pussy. Mark's cock throbbed at the sight of the hairless, perfectly tanned flesh and without a though he reached out his hand to touch the object of his fantasies.
