Cindy watched her mom climb into Dr. Johnson's Mustang and wave goodbye. Dr. Johnson leaned out the window, shades on, waved, and then the black sportscar roared out of the driveway and was gone. Cindy sighed with relief. The house was hers. Mom and Dr. Johnson were on their way to St. Maarten for a week. It sounded exotic. It sounded wonderful. It sounded like Cindy might have a step-father one of these days. But what it meant, right now, was that, two weeks into summer break after her junior year, Cindy had the house to herself, and plenty of friends in town.

She closed the door and walked upstairs. Once in her room, she quickly shed her shorts, t-shirt, and panties. She pulled a thong bikini out of the top dresser drawer. It was a flirty yellow one. She tied on the bikini bottom, then tied on the top, and looked at herself in the mirror. Two weeks after finals, and she had already toned up all the little things she had let go while desperately studying her ass off. She turned around and looked at her ass. Tight and firm. She smiled. Cindy tossed her black hair, grabbed a towel, and walked out of the back door to the pool.

Sitting on a float, she rubbed lotion on her body, then laid back and closed her eyes. She smiled, remembering the night before.

Dr. Johnson had come in for dinner and to spend the night, so that he and Cindy's mom could leave early the next day. He was as hot as Cindy had remembered him, a muscular, fit man in his mid forties, with just enough grey in his dark hair to make him distinguished, without being old. Cindy's mom had made herself up, and was wearing a tight dress for him. Her body was better than most of Cindy's classmates'. The two of them made a gorgeous couple, and Cindy was sure they'd turn heads on the beaches of St. Maarten.

The three of them had enjoyed a Korean dinner, and enjoyed even more some soju afterward. Dr. Johnson and Cindy were fine with their liquor. Cindy's mom, however, was a lightweight, and after a couple of shots she was giggling and red-faced. The three of them talked and drank for a couple of hours, all the while the sexual energy in the room building. Cindy vividly remembered the feel of Dr. Johnson's cock inside of her, and she enjoyed the memory. She was wearing a short, tight miniskirt, and as they sat in the living room her long, toned legs were fully exposed to Dr. Johnson. He was clearly enjoying the view. Mrs. Kim had let her dress creep up her legs, as well, and Dr. Johnson's hand was on the inside of her thighs.

Cindy shifted in the float, feeling her pussy become moist as she remembered watching Dr. Johnson's hand move slowly, brushing and caressing her mom's pussy through her panties. Her mom had smiled at Cindy, had kissed his neck. Cindy had watched, motionless, as her mom had reached down, rubbing her small hand down his body, to his bulging crotch. He had moved his hand, lifting up the hem of her dress, rubbing her pussy, her legs spreading to accomodate him.

Then he had slipped his hand into her panties, fingering her clit. Cindy had watched the outline of his fingers inside her mom's white panties, stroking, probing. She had watched her mom eagerly unbutton his jeans, unzip them, reach in and pull out his hardening cock, her hand tiny on it. Her mom and leaned forward, kissing it, beginning to lick and suck the head, her eyes closed. Dr. Johnson, however, had stared at Cindy, smiling, enjoying the feeling her mom was giving him. Cindy had stood from the chair, unzipping her skirt, letting it fall to the floor. She had stripped off her tight t-shirt blouse, and had removed her bra. Standing just in her silky black thong she had begun to touch herself, caressing her breasts, moving a hand down inside her thong, masturbating. He had watched her as her mom sucked him. Cindy stared back into his eyes, feeling herself become more and more aroused, pleasuring him by the sight of her body, of her actions, as much as her mother was pleasuring him with her mouth. She turned, bent over, stripping down the thong, and she spread her legs, leaning forward, one hand on the chair, the other between her legs, playing with her twat. She heard him cum, grunting, her mom's moan of pleasure as his chism shot into her mouth. She heard her mom swallowing, then licking him.

Cindy moaned softly at the memory, sliding a hand down the front of her bikini, touching her erect clit, feeling a thrill of ecstacy shoot through her body. Dr. Johnson had risen from the couch. Cindy had turned, watching him approach, his cock hard. He had grabbed her hips, and she had touched his cock, guided it in as he thrust forward. His manhood had invaded her slowly but confidently, pushing in inch by inch, bringing her closer and closer to climax. Her mom had moved next to her, stripping out of her dress, out of her panties, then touching Cindy's body, kneeling, mother and daughter kissing passionately as Dr. Johnson began to fuck Cindy harder and harder. It was a slow, powerful fuck, each thrust hitting Cindy perfectly. She had cum for them, pushing her twat back into Dr. Johnson's crotch, moaning into her mom's mouth. He had leaned forward, reaching around her, squeezing her breasts. Her mom had moved a hand along her abs, down to her clit, fingertips touching her even as Dr. Johnson pushed into her again. Cindy had cum again for them, overwhelmed with pleasure.

On the float, she arched her back, rubbing her clit harder, her eyes closed, the warm sun on front, the cool water on her back. Dr. Johnson had at last pulled out of her, had turned his hard cock to her mom. Mrs. Kim had sucked Cindy's juices off his pole, and then he had laid down, and she had squatted over him, taking his rod into her cunt. Cindy had sat on the floor, watching her mom lower herself onto him, then grind her pussy back and forth on him.

Dr. Johnson had laid back, feeling the pleasure, loving it. Then Cindy had mounted his face, feeling his tongue flick her cunt, and she and her mom had kissed again, both of them taking their pleasure from this man. They had stayed in that position, Cindy and her mom cumming together, until Dr. Johnson hit his orgasm again. Then the three of them had laid on the living room floor, kissing and touching, until Mrs. Kim and Dr. Johnson had gone to their bed, and Cindy to hers.

Cindy felt her orgasm coming on as she lay on the float, and she spread her legs, arching her back, moaning with pleasure, rubbing her clit hard and fast. She came, nearly falling off the float as her body spasmed. Ecstacy racked her body again and again, her muscles tense, until finally her orgasm subsided. She lay back on the float, sliding her hand out from her bikini, licking her fingertips. She opened her eyes, and almost immediately saw him.

Sometime while she had been away at college the people next door had sold their house. They had been an old couple, very nice. She had never met the new neighbors. But one of them was staring at her out of a bedroom window. She had a little trouble telling through her shades, but he looked like high school kid. Maybe fourteen or fifteen. He was looking down from an open window on the second floor, right into her back yard, right at her as she lay on her float. Cindy cursed under her breath. He had probably watched the whole time as she had masturbated there.

She pulled back her hair and closed her eyes, putting it aside. If she was going to play with her pussy outside, that was what was going to happen. The guy probably had his own pants off, anyway, and he was probably working his cock at that moment. Cindy turned over, pretending not to have seen him, and untied her bikini top, pulled it out from under her, and tossed it to the poolside. Then she untied her bikini bottom and carefully pulled the strings down so that the thong strap peeled away from between her buttocks, and she nestled them in a little pile between her thighs, covering just her twat. The boy, from his window, would now see a fully nude woman, with just a little pile of yellow fabric to obscure his view of her pussy. Cindy crossed her arms and lay down her head, closed her eyes and dozed off at the thought of her observer watching her, for all purposes nude, floating about the pool.

When Cindy awoke it was nearly noon, and her stomach was beginning to growl. She had skipped breakfast, and she was hungry. She blinked her eyes in the bright sun, nearly blinded by the light reflecting off the pool. She sensed immediately that she was nude, and that keyed her memory as to why. She smiled, looking around. She saw no one in the window.

Then she saw him at the poolside. He was sitting at the deck table, drinking a soda from through a straw.

"Hi," Cindy said, trying to sound nonchalant, but really a little alarmed that he was there when she had been sleeping.

"Hi, yourself," the boy said. He was tall and slim, probably, as she had initially guessed, about fifteen. He smiled pleasantly, "Did you have a nice nap?"

"Did you get a good look?" she replied.

"The view is excellent," he laughed. "Much better than from in my room."

"I should hope so," she said. She continued to lay on the float. There wasn't much point in doing anything else. Her bikini top was on the table in front of him. The bottom was still under her, but the thong was more a formality on her rear than any true covering.

"You must be Cindy," he said, walking over to the pool and sitting at the edge, his bare feet in the water. He leaned forward and extended his hand. Cindy shook it, the motion causing her float to drift toward him.

"That's me," she affirmed. The float bumped against his shins. He looked down at her body, laid out immediately below him in all it's naked glory. She could see the bulge straining against his shorts. At least he really liked the view. He was playing it very cool for a high school guy, though. She asked, "And what's your name?"

"Your mom never mentioned me?" he asked, seemingly surprised. "I'm Keith. My mom and dad moved in here last year."

"No, she never mentioned you," Cindy said. "Does she babysit you?"

"Ha ha," he snorted. "No, I mow her lawn."

"The grass needs trimming," she said.

"That's not why I'm over here."

Cindy looked up at him, hanging on to the edge of the pool next to him, "Oh, really?"

He nodded, "I came over to see if you wanted to fuck."

Cindy raised her eyebrows, surprised at his candor, if not at his desire. She almost smiled, but replied, "Does that line work for you often?"

"Not yet," he said.

"Not likely to today, either," she said cooly.

"I know. It's too bad, because my parents are out for the weekend, too. When I first saw someone in the pool, I thought it was your mom, and I figured I come over here and see if she'd let me fuck her. I mean, she looks like a pornstar in her bikini, you know. But then I saw it was you. She must have looked just like you eighteen years ago. You're the hottest chick I've ever seen. So, I figured, what the hell, I can only imagine how you'd be in the sack."

Cindy stammered, "You can go on imagining." He was totally brazen. His confidence was sexy, but she was taken aback. Nevertheless, she found her pussy getting wet as he stared at her, not bothering to hide his lust at all.

"Come on, I saw you playing with you pussy. You're horny. Why not let me eat you out, give you a good fucking, let you hit your orgasm on my cock."

"What makes you think you can handle me?" she asked, trying to take charge, put him on his heels. She reached over to the concrete poolside, pulled herself up off the float, leaving the bikini bottom behind. She stood next to him, nude, pulling her hair back, letting him look at her nude body, his face at the level of her shaven twat. That sight alone would floor this high school guy, make him helpless with lust, make him lose his cool.

He licked his lips, said, "Because my cock can stay hard all day and all night. And for you, it would."

"But do you know what to do with it?" Cindy asked, giving him a look that said clearly what she thought the answer to be.

He shrugged, staring up and down her nude body in awe, "I figure I'm like an academician. I've done the studying, done all the booklearning, but I've never had the opportunity to put it into practice. But sooner or later, I've gotta put my theories to the test."

"I'm your lab rat?" Cindy asked.

He shook his head, laughing, still cool despite being within arms reach of such a hot body, "No, no. More like a professor. I'm doing a practicum, you're giving me the evaluation, highlighting the learning points, training a future master."

"Master!" Cindy laughed. But she was completely turned on. He wasn't bad looking, he was certainly cool under pressure, and he was funny, witty. She was curious. She cocked her head to the side, "Well, if you're going to be master of anything other than your left hand, you'd best at least have the fundamentals for the job. Let's see what kind of natural talent you have going for you."

"You mean..."

"Take it off," Cindy said.

Keith looked around. Cindy asked impatiently, "Hello.... I'm nude over here." He looked her up and down again, as if confirming it, though he'd been staring at her bare body for several minutes. He took one more look around, then began to take off his clothes. He stripped off his shirt quickly, tossed it on the table, revealing a thin body, not skinny, but with lean muscles that hadn't bulked up yet. He pulled down his pants and nearly fell into the pool taking them off. Cindy stifled a chuckle. He was overly eager now, actually hoping that he might get laid, and with one of the hottest chicks he had ever seen. His armor of cool was falling apart. He kicked off his shoes, then pulled down his boxers and stood up again, clutching them in his hand.

Cindy's eyes opened wide in surprise. His cock was rock hard, erect, standing straight out and angled a little up. The head was purple, a little glisten of pre-cum already at the meatus. He was long, a good eight inches, much bigger than she had expected.

"Wow!" she said, smiling. "You DO come equipped for my classroom." She laid a hand casually on his cock, felt it quiver with her touch. He moaned softly. He was already so close to cumming. Cindy smiled, turned, and walked toward the house, letting him watch her ass in motion. At the glass door, she turned, looked over her shoulder at him, and motioned with her finger for him to follow her.

He hurried in after her, catching her just inside the door. His arms wrapped around her, his cock pressing against her lower back, one hand finding her tits, the other moving down and rubbing her clit hard and fast. He kissed her shoulder passionately, moving his pelvis back and forth like he was trying to fuck a hole into her sacrum.

"OH!" she cried, "Slow down, tiger!"

She tried to pull away from him, but he was hanging on tight, and she only managed to fall over. She landed on her hands and knees, him behind her, on his knees. He gripped her hips, positioned his cock behind her. Cindy knew he was going to thrust, tried to reach back between her legs and bring his cockhead down to her wet pussy lips. But he pushed forward hard and fast. His cockhead bounced off her cunt, angled up, and powered right into her ass.

"OHHHHHH!" she cried, her eyes opening wide at the unexpected invasion.

"Oh, FUCK YEAH!" he moaned. "Oh your pussy is TIGHT!"

"That's...UHHHHHHNNNNN" she cried, trying to tell him what he was doing, or, more precisely, what he was fucking, but he was pounding hard and fast, his big cock pistoning into her ass with powerful, quick bursts. "OHHHH OHH OH OH OH OH OHHHHHH!" she screamed.

He rammed to the hilt inside of her, pulling her back with all his strength, her buttocks pressing against his hips, his pelvis rammed against her ass, his cock buried within her. He cried out, "FUCK YEAAAAAHHHHHH!" and his cum shot into her, a powerful burst of juice deep inside her ass. He held her tight to him, pumping into her ass, his cum filling her rectum. Cindy screamed out, enjoying the feel of his cock so far in her, but wanting him to finish his orgasm so she could get fucked properly by that big rod. He seemed to cum forever, his body quivering with each spasm, gasping and moaning with pleasure. Finally his grip on her hips relaxed, and he leaned forward.

With his mouth next to her ear, his cock still deep in her ass, still hard as iron, he asked, "Did you cum, baby? Was it a good fuck?"

She whispered, "Baby, I don't usually cum when I'm ass fucked."

"Ass fucked?!" He said, raising upright, looking down, pulling his cock an inch out. She almost giggled, looking over her shoulder at him, as he stared down at the sight of his cockshaft rammed in her ass. "Oh shit!" he said. "Oh shit I'm so sorry! Oh, fuck, are you okay?" He pulled his cock out of her quickly, and stared down at her, full of concern.

Cindy rolled onto her side, laughing, facing him, and reached out and stroked his cock, "I'm fine, Keith. I'll probably walk funny tomorrow, but I'm fine. You sure do have the enthusiasm for my class. Let's work on foreplay a little, hmm?"

"You're not mad?" he asked, staring at her small hand on his cock.

She shook her head, "No. It's a little flattering to have someone so...excited. Come on, let's wash off your cock. It's still got alot to do today."

She led him to the bathroom and turned on the shower. He leaned back against the sink, watching her every movement as she leaned over, closing the drain, turning on the shower. She felt the water, waiting until it was warm, but no hot. Then she got in, and motioned for him to follow. She backed under the water, feeling it course over her shoudlers, down her back. When he was in the tub, she put her arms around his shoulders, drew him close, stood on the tips of her toes, and kissed him. He pushed his tongue into her mouth, and she withdrew, put her finger to his lips, and kissed him again. This time it was a nice kiss, soft and passionate. She opened her lips slightly, touched her tongue to his lips, then to his tongue. His hands moved around to her back, down to her ass, squeezed it, then moved up, exploring her body. His cock pushed against her firm abs. Cindy dropped a hand down as she kissed him, moving it down his body, to his cock, and she fondled him softly, eliciting a soft moan. She disengaged from the kiss, turned, took the soap in hand, and with both hands began to massage the soap over his cock and balls. He stood, watching, gasping with pleasure. Cindy replaced the soap, rubbed the suds all over his manhood, then took a wet washcloth and cleaned him off.

She smiled at him, knelt down, and kissed his cockhead. He groaned, watching, his hands touching her wet black hair. Cindy ran her tongue up and down his cock, kissing the shaft, then taking the head in her mouth and sucking him. He moaned, smiling, staring at her. She popped her lips off his cock and smiled, "Tasty. Perfect. But you've already cum once. Let's work on how you get me off."

She stood, pushing him down to a kneeling position. She raised a leg, placing her foot on the edge of the tub, feeling the water on her back again. She said, "Touch my pussy softly. Just the lips first."

He moved a hand up, gently touching her engorged lips. Cindy moaned happily, "Good. Oh, yes." She reached down, placing her fingers on his, guiding the way he moved his hand on her. She moved his fingertips up to her clit and said, "That's the hot button. Touch me there." He did, moving his fingertips back and forth on her clit. With his other hand he resumed stroking her pussy lips, and Cindy gasped with pleasure. He was good. She moaned, "Slide a finger in me...slowly." He pushed his index finger into her cunt, sliding an inch into her, hesitating, moving back and forth, watching her reactions carefully, and then pushing in a little deeper, all the while massaging her clit. Cindy smiled happily at him, touching her own breasts, breathing harder and faster. He pushed his finger into her, knuckle deep, and she moaned. He began to fingerfuck her, slowly, continuing to work her clit.

"Kiss my clit," she begged. He did, leaving his one finger buried in her cunt, kissing her engorged clit, then flicking it with his tongue. It felt amazing. Cindy leaned back against the wall of the tub, turning the shower water on her face and chest, letting it run down over her cunt, over his tongue and he worked her clit, all the while driving his finger in her, turning it, keeping her going.

"I'm gonna cum!" she screamed, and then she did, her orgasm surging suddenly over her body. She clutched her breasts, arched her back, felt her knees wobble as his finger and his tongue kept working on her, intensifying her climax, lengthening it, bringing her to the point she thought she would collapse.

At last her orgasm subsided. She looked down at Keith, her breasts heaving. He smiled up at her, his finger still deep within her. He stood, sliding his finger out, rubbing it on her clit softly, and she kissed him, more passionately than before, pressing her breasts against his body, happily feeling his cock push against her abs, all the while feeling the thrill of his finger on her clit.

"Come on," she said urgently, "Time to learn how to fuck me."

She led him out of the shower, and the two of them shared a towel, drying each other quickly and eagerly. In the bathroom, Cindy knelt down, took his cock in both her hands, and began to blow him, wanting to taste that wonderful cock again before she felt it in her cunt. He was so hard, so eager for her. She sucked him deep, massaging his shaft, his balls.

"Oh, God, I want to cum again," he moaned.

She paused, said, "Go ahead, if you can keep it up to fuck me."

He nodded. Cindy slid her mouth over his cockhead again, sucked him hard and deep, squeezing the base of his shaft, stroking his balls. He moaned, tensed, and shot a thick wad of cum deep in her mouth. She swallowed, jacking his base, sucking him, feeling blast after blast of hot cum hit the back of her throat and slide down as she swallowed quickly. She slid her mouth off of him, licked and sucked his cockhead while the last of his cum oozed out, and then she smiled up at him.

"That was so hot," he groaned.

"Now I want this cock in me," she said. "Can you keep it up?"

"For you, all night," he sighed.

She stood, led him to the bedroom, and laid down on the bed. She laid back, spreading her legs, and he climbed on top of her. This time he was calmer than before, no less desirous for her, but his fire less urgent after cumming twice. He kissed her, his lean body pressed against hers. She ran her hands down his back, enjoying the feel of his tongue touching her own, the feel of his hard cock pressed into her abs. He moved back, and she ran her hands around to his abs, down to his cock, and stroked his manhood. He stared at her hands as they guided him down, moving his cockhead until it pushed against her cunt. He pushed forward, his cockhead slipping into her bare shaven cunt. She arched her back, gasping, legs spread wide. He pushed forward more, his shaft beginning to dive into her. She pushed him back out, till just his purple head was inside, then allowed him to push in once more. She eased him in that way, allowing more and more of his shaft in with each thrust, until at last he was fully inside her, and she came.

Cindy arched her back further, closing her eyes, bringing her heels up to his back, her breasts heaving with her orgasm. He remained buried to the hilt in her, motionless, watching and feeling her cum on his cock. He moved his cock within her, keeping her climax going, and then he began to thrust, moving his arms under her thighs, his hands on her waist, on his knees, his cock buried inside her, ramming her harder and faster. Cindy brought her heels up to his shoulders, feeling him invade her deeply, feeling her orgasm build and release again. He pounded her pussy eagerly, enjoying her ecstacy almost as much as she was. He leaned forward, coming more over top of her, bending her knees back to her shoulders, her ankles at his ears, and he fucked her harder, bringing her off again and again.

He rammed her deep and she felt him tense, felt his muscles become rigid. She came with him, feeling his hot cum spurt deep within her, hearing him groan with ecstacy. He came hard and long, all the while grinding his cock hilt deep inside her, giving her a powerful orgasm. She screamed with him, clutching the sheets. At last she felt his cock slip out of her. She straightened out, legs spread wide, laying, panting, on the bed, staring up at his sweaty body, his rock hard, swollen cock. He reached down, turned her over, brought her up onto her knees. He moved behind her, and she reached between her legs, found his cockshaft, hot and hard. He pushed forward, sliding into her wet cunt this time. He thrust all the way in, pulling her hips back. Cindy buried her face in the sheets, biting the fabric, clutching it with her hands, cumming immediately. Behind her he began to thrust, hard, long, fast strokes, smacking his pelvis against her ass. He took her from behind, his confidence growing, watching and listening to her cum for him again and again. After a good, long fucking he pulled out, laid back, his cock standing straight in the air. Cindy straddled him, facing him, pulling her hair back and smiling. She eased herself down onto his cock, taking him inside, riding him, feeling her orgasm build quickly, and then she took him fully inside, cumming on him. She fell forward, kissing him, moving up and down on his cock, his hands on her hips, caressing her body. She rose up again, allowing him to see his cock impale her, taking him in faster and faster, driving him toward another climax. He came inside her, closing his eyes, spasming with the effort of yet another orgasm. She climaxed with him, the two of them writhing together, and then she fell onto him, sliding off of his cock, kissing him.

"You're one hell of a student," she cooed, caressing his cock as they kissed.

"I just have a great teacher," he replied.

"And to think this was just the first lesson of summer sex school."

"Hopefully the first of many."

She kissed him, "Absolutely."
