Introduction: Janice, Tommy's mother; and Tommy, her 18-year-old son, are spending Labor Day on a boat Janice has rented. It's a small boat, not a yacht, but you don't need a yacht to have fun.
Chapter 1
The gentle rocking of the boat felt erotic to Janice.
She was lying on the deck, her tiny bikini hardly concealing the smooth flesh of her body. The small halter top barely held her sharply thrusting tits, and the bottoms were nothing but two skimpy triangles held on her hips by two fragile strings tied in bows at her hips. Her long legs were parted, the sun beaming its heat upon the crotch of her bikini.
She was on her back, one slim arm over her eyes, trying to doze.
The boat was not a big one, a Cris Craft 32 ft., with a cabin that had two beds, a stove, refrigerator and the usual amenities required for a few days on the water. The only thing she didn't like about it was the tiny head, a space hardly big enough to sit and piss in comfort, not to mention a decent shower. Janice was sure that all boats this size were designed for men. All they had to do was unzip, haul their cocks out and piss away. But a woman needed room, comfort to sit and take her time.
Inside the cabin, her son, Tommy, was peeking at her. He could look up between his mother's long, smooth thighs. Tommy had just turned 18, and she knew he was naïve when it came to women. His dating life was almost nil, he preferred to spend his time building model airplanes. He looked younger than 18 because of his baby face. His girlfriend, Sally, thought he looked like a girl.
Tommy found the puffy crotch of her bikini fascinating. He was sure he could see the slit of her cunt, but perhaps that was only his imagination. It sure looked like a pussy! One thing he could see, though, was the way her bikini bottom was puffed out by the thick curls of her privates.
Tommy loved to look at his sexy mother, imagining her naked, letting him look at her cunt, her tits, her wonderful, tight, round ass. His cock seemed to have a perpetual hard-on whenever he was around her. He wanted to show his hard-on to his mother, to get her comments on it, to admire it, to praise it. Like most kids his age, he was proud of the size of his penis. It was a long cock, and thick enough. He eased his cock from the leg of his swimming trunks and began to fondle his cock as he watched her.
Janice knew Tommy was peeking at her.
She had discovered that the first day on the boat. At first it had angered her, but then it had pleased her. She knew she had a beautiful body, and she loved to have it admired.
Janice giggled softly, squirming her ass against the deck. She knew she wanted to strip naked, and to have Tommy naked, but what would her son's reaction be? She knew he'd get a hard-on. She had seen it a few days ago. She had been a little careless and sat with her knees up, her dress on her thighs. He had seen her panties then, and his cock had gotten very hard. She had been startled initially, but then she felt a lovely wet sort of heat, and she had sat that way while her son sneaked peeks under her dress.
Janice began to shiver, then tremble. She felt wetness between her thighs, and she resisted the urge to rub her cunt. That would be going too far, she felt, with Tommy looking at her. She wondered if he was playing with his cock now, stroking it while watching her.
To her surprise, Janice had an orgasm. She could feel her cunt clasp and twitch inside the tightness of her bikini bottom. She wondered if her son could see what her cunt was doing.
Tommy could not see his mother's cunt convulse, but he could see her writhe her ass on the deck, while her long legs opened and closed. He was breathing hard, gripping his cock as tight as he could. There was a strange tingling in his balls.
He began to groan, squeezing his cock as hard as he could, the head of his cock bulging and clear juice beading at his piss-hole. He wasn't sure what was happening to him, but he loved the sensations that flooded his teenage body.
Janice rolled onto her stomach, still with her legs wide apart. Now Tommy was looking at the compact swells of his mother's ass.
Janice twisted her ass, bunching the asscheeks, squeezing them together, feeling wicked, knowing she was teasing her son.
The tingling faded in Tommy's balls, replaced with an uncomfortable fullness that was slowly becoming painful. It was unlike any pain that he had ever felt. It soon became excruciating.
Almost sobbing with pain, ignoring the fact that his cock was out of his swimming trunks, he clutched his balls tenderly, then hobbled up the steep steps and onto the deck.
"Mom, it hurts!"
Janice turned onto her side, eyes widening as she saw her son's cock standing out stiffly from the leg of his trunks.
"Tommy, what in the world are you --"
"Mom, they hurt a lot!"
Concern showed on her lovely face. "What hurts, sweetie?"
"These!" Tommy sobbed, holding his balls gently. "My balls are killing me, Mom!"
Janice suddenly understood. She lifted her hand for him to come closer. As he approached stiff-legged, Janice found herself unable to take her eyes off his cock. His prick was long, thick, and very hard. The head looked very swollen. When she saw the clear juices glistening on his piss-hole, she knew what his pain was. A smile flickered across her face.
"I understand, darling," she said softly. She placed her palm on her son's shaking thigh, pulling him closer to her. "It's my fault, baby. I knew you were peeking at me. I shouldn't have teased you."
"Fix it, Mom," he gasped. "Make it better, Mom!"
"I will," she whispered softly. "Let mother make it better."
Sitting up, knees bent and spread open, she pulled her son between her feet. Her hand moved up the leg of his shorts in back, and she cupped one cheek of his hard ass. Gently pushing his hand away from his cock, she closed her fist around his prick and began to stroke it gently back and forth.
Tommy, with tears of pain in his eyes, watched her, arching his hips forward.
Janice jacked his cock, but the motion created another wave of pain in his balls.
"Here, let me take them out, too," she whispered, lifting his balls free of his trunks. She sucked in a deep breath as she stared at his cock and balls, her cunt vibrating with a wet heat. Her tongue ran over her lips, and she swallowed nervously. She fondled his swollen balls.
"Don't worry. I know about these things. Mother will fix it."
She began to slowly and gently pump his cock, closing her other hand very carefully about his balls. Her bikini bottom was becoming soaked in her pussy juices, showing wetly through the thin fabric.
"Ohhh, Mom, not so fast!"
"I'm sorry, baby," she whispered, slowing the motion of her sliding fist.
She watched juices bubble from his piss-hole, making her hand slippery. The itch started in her palm, grew along her wrist, then she groaned softly as a second orgasm contracted her cunt. Her eyes slitted with fiery ecstasy as she came while gripping her son's cock in one hand, cradling his hard balls in the other.
"Mom, it still hurts a lot!" he cried. "Please, do something!"
Janice realized her pumping fist was causing him even more pain. She didn't know what to do in order to help relieve him other than jacking him off. But the pumping of her fist seemed to hurt him more. Taking her hand off his cock, she watched it jerk up and down before her face. She stared at it, then her lips parted.
Even as the thought came to her, she was moving closer to his cock, licking her lips. Tommy was almost crying with pain now.
"Let me... "
