"Like, uh… you know!" Billy tried desperately to think of something. "Like…" he snapped his fingers excitedly. "Like swimming in the nude! That's it! Stuff like swimming in the pool in the buff. Me and my pals used to do that all the time, when Mom was gone – which is most of the time!"
Sandy laughed, although there was a growing excitement in her cunt which made her feel more aroused than amused. She stroked her cousin's neck.
"Why, Billy, we can still skinny-dip!" the blonde giggled. "We used to do that all the time up where I come from, girls and guys together. No big deal!"
"Really!" Billy gulped, his eyes running over his cousin's lush frame hungrily.
"Sure," Sandy lied easily. "I'm not ashamed of my body! Are you ashamed of yours?"
"…No, hell no!" Billy protested, turning redder than he had been earlier.
"Good! Come on, let's take a quick swim right now, to close the deal!" Sandy suggested, taking his hand. "It's already eight degrees outside at ten in the morning. Sure gets hot down in this country in August!"
"Yeah, uh… yeah! Sure does!" Billy agreed uneasily, following the girl as she towed him out into the family room and up to the patio doors.
Sandy unlocked the glass doors and pulled Billy out onto the deck in the bright, morning sunlight. The weather was warm enough for suitless swimming, Sandy reflected as she slowly unbuttoned her robe.
"Come on, you too!" she chided Billy. "This ain't no striptease, it's a swim party!"
"Uh, yeah!" Billy agree… gulping back his fear and unbuttoning his shirt. "Yeah, right!"
The nervous teenager pulled his polo shirt off, baring his tight muscled swimmer's physique. He stepped out of his thongs and undid his pants. His fingers shook as he tried to nudge the sticky zipper downward.
"Here, let me do that!" Sandy offered, taking the hunk of reluctant metal from his jerking fingers and tugging it down.
"I… I can do the rest!" Billy babied anxiously, turning away from the girl and walking rapidly to the edge of the deep blue pool.
The nervous teen shucked off his pants and doffed his shorts in one quick move and dove in. Sandy giggled as he cut the surface, realizing that he already had a hard-on and that he had been embarrassed to have her see it.
Slowly, sensually, enjoying each button's tantalizing quality as she popped it open, Sandy walked to the pool.
"Just tell me if you like what you see!" Sandy purred as she stood before him, sliding the filmy garment off her shoulders, letting it flutter enticingly downward until her tits and, finally, her perky nipples were exposed.
Sandy stood on the side of the pool, her hips shifting slowly from side to side, as her robe drifted downward across her back and her little tummy. The blonde seductress moved her hands, forcing the material to sweep out past her bent knees, baring her shapely legs all the way up to her taut, soft thighs.
Grinning, Sandy dropped the robe and opened her legs, aiming her cunt directly at Billy's entranced eyes and shaking her hips. The girl's tits rolled and jerked.
"Oh, fuck!" Billy gasped.
"Maybe, if you're lucky!" Sandy smiled at him and straightened up.
The deep tanned girl dove into the cool, refreshing water and came up across the pool from her wide-eyed, red-faced cousin. She feigned a shiver and motioned to him.
"I'm a little cold, cousin Billy!" she cooed. "Do you suppose I could talk you into swimming over here and holding me just a little, to kind of warm me up?"
Billy sunk nearly out of sight in shock, but he swam quickly toward her. He paused when he reached her.
"Come here, Billy, don't be shy!" Sandy urged him, her arms extending out of the water to him.
Billy's mouth dropped open and he swallowed some water as the girl's pink nipples poked out of the pool. As Billy eyed her tits longingly and treaded water, Sandy realized that she was dealing with a boy who was as virginal as she had been before her arrival in the big city.
"I caught you fair and square. You just be still while I reel you in!" Sandy giggled, reaching down and capturing the boy's cock beneath the water.
"You! You're touching my… my." Billy screamed with surprise as he felt his cousin's fingers around his rigid prick and felt her towing him in toward her by his stiff cock.
"Mmmmmm, you bet, honey," Sandy cooed. "I got your cock and I'm not gonna let go until I feel it squirt!"
"Ooooooooh!" Billy groaned by way of a reply, closing his eyes with pleasure as Sandy began pumping the skin on his erect prick up and back as she pulled him to her. "If… if you keep doing that… it won't take long!" he moaned.
Sandy stopped her quick motions and looked down through the water at the cock that she held in her hand. Billy's cock was a nice, reassuring handful – or cunt-full for a girl – but not in the monster-prick category of his father and older brother's impressive pricks.
Just the right size of cock that a virgin with an exceptionally tight pussy might need to pop her cherry with, Sandy thought with rising excitement. She had started into this teasing, pleasant diversion thinking only about toying with her cousin until he shot his boyish wad in his pants, or maybe jerking him off until he came. But now! Now Sandy could see definite possibilities for her cute, small-cocked cousin.
"How would you like to fool around inside, on the bed?" Sandy asked coyly, stroking the boy's cock as she smiled at him.
"You… you mean like… like… this?" Billy blurted, his hand darting out to capture her floating tit in his inexperienced grasp.
Sandy grinned and moved closer to him, forcing more of her buoyant titty into his hand. "Sure, stud," she purred, fondling his balls with her fingertips as she moved the skin slowly back and forth on his cock. "Maybe I'll even suck this hot piece of cock, let it shoot in my mouth… before I let you fuck me. What do you think about that?"
"I… I… oh, fuck! Fuck, I'm gonna blast!" the excited teenager yelled.
"Don't!" Sandy pleaded, surprised by the boy's lack of control. "You mustn't waste it!"
With that, Sandy took a deep breath and dove straight down. She opened her eyes and saw Billy's jerking cock only a foot in front of her face. Moving forward, Sandy opened her mouth and took the head and half of the boy's prick in her lips and expelled pool water from around his cock in a tight, ring-like jet that pushed his sparse pubic hair against his clenching nut sack.
"Oh! Oh, God, your mouth! It's right on my… I'm cumming!" the boy squealed as his heated fluid coursed out of his balls into his cousin's warm mouth.
Sandy sucked on Billy's cock as it shuddered within her lips. The golden-haired girl moved in closer, taking all of his engorged prick into her mouth and throat.
"Bill!" Sandy gasped beneath the surface as his bloated prick jumped twice in her mouth, then flooded her oral cavern with the biggest surge of semen she had ever imagined.
Billy's cock was like an uncorked champagne bottle in Sandy's gulping mouth. The heady, steamy jism streamed into her throat, filling her cheeks again and again as she swallowed the burning pudding and held her breath.
The teenage seductress bobbed her head in and out, making the boy's prick jerk and shoot even more of the thick goo into her sucking lips as she tongued him and swallowed. Sandy couldn't believe the amount of sticky, super-slick jism her cousin's nuts were pouring into her mouth.
Nearly blue as the water from lack of air, Sandy at last let his pumping cock slip from her lips and rocketed to the surface. Gasping and choking, the pretty little blonde gulped in oxygen as eagerly as she had swallowed her cousin's cum. She felt Billy's prick jet two more loads of warm jizz up against her heaving belly as she struggled to stay afloat and breathe. He held her close.
"That's it, baby, breathe, breathe!" Billy urged her gently, trying to help her keep above water. "God, it felt so good when… when you did it!"
"Ummmp! There's a lot… more where that… gasp… came from, if you can keep me from drowning!" Sandy tried to smile as she battled to keep her chin afloat and fill her lungs.
