He knew someone was watching when he heard her gasp. He opened his eyes to see Denise Fuller, his best friend's mother, staring with her hand covering her mouth. His hand stopped moving on his hard cock. They made eye contact, and he froze in terror.
"I--" she began, her eyes returning to his cock. Then she turned and left the room without another word. He felt panic spread through him as he yanked up his underwear and tried to figure out what to do.
It was the summer of 1989, two weeks after Adam's high school graduation. He had moved in with his best friend Kevin's family after his dad was hired by a firm in Albuquerque. Kevin and he had already been accepted into Madison the next fall, and he had a job at the grocery store. It made no sense for him to move to New Mexico only to return a few months later. He helped his folks pack, waved as they pulled away, and then climbed into the station wagon with Mrs. Fuller.
There were four members of Kevin's family. His older sister Angie was at school in Chicago but made frequent visits home for the weekend. His father Dwayne was a quiet, generous man who worked long hours as an insurance adjustor. His mother Denise was a homemaker, about to send another child off to college. When she heard of Adam's predicament, she immediately offered to put him up for the summer in the spare bedroom in the basement. Adam's parents were wary at first, but he had been friends with Kevin for years. They knew the Fullers well. As for Mrs. Fuller, he thought she saw the summer as a last chance to glory in running the household. He only added to her happiness. She was a stunning host, cooking hearty dinners and keeping them all active with field trips and holidays. She had refined hospitality far beyond anything his mother ever achieved.
Mrs. Fuller was lithe and athletic, with sandy blonde hair and tan skin. Her cheeks took on a light dusting of freckles in the summer sun. She maintained her figure through punishing exercise, and her arms and calves were strong. But her hips were soft and voluptuous, with a mature substance. Her breasts were large and firm.
They spent many summer afternoons out by the pool in the immaculate backyard, drinking lemonade and eating sandwiches. One Saturday when Angie was home from school in Chicago, she swam in a bikini, and her pert nipples and shapely ass made him swoon with lust. She had nothing but disdain for Kevin, and Adam was scorned by association. Still, he felt that she had to appreciate the lust between them, that she might succumb if ever she could feel it.
But mostly, he admired Denise, as she insisted he call her. She was so unmotherly in a swimsuit, with a curving sensuality where Angie was stiff. She also had a playful sense of humor and took a genuine interest in his opinion of things.
Then, just as he was settling into his new home, Kevin and Dwayne left for a long-planned fishing trip to Montana. They had made the trip every year since Kevin was 12, though this time they were taking an extra week. They had invited Adam out of courtesy, but he knew the trip marked the end of something, that it would be better not to intrude. That Saturday, Denise and he had dinner alone together for the first time. They discussed families in the neighborhood and movies and history and religion. He couldn't believe they were going to be alone together for two weeks.
The night she caught him, he had worked a busy shift at the grocery store on a hot summer afternoon. He returned home in time for dinner, but they talked less than usual. After the news, he excused himself to take a shower. There was a bathroom in the basement, so it was easy to shower downstairs and walk in a towel back to his room. The bedroom was a shoe box, but it got decent light and stayed cool on hot days. The problem was that it had only a curtain for a door.
After the shower, he walked into his room, dropped his towel, and took his hard dick in his hand, working his fingers over the head. It had been a frustrating afternoon, and he hadn't made himself come in days. He laid down on the bed and closed his eyes, remembering Angie's swollen nipples straining against the fabric of her swimsuit. He wanted to rub his palms all over her breasts, to grab her taut ass cheeks and pull her groin into him. He wanted to whisper into her ear, "You have to let me fuck you. I need it so bad."
Then the gasp. Denise had slipped into the room while his eyes were closed, silently through the curtain. She must have been on some errand and never suspected that he might be touching himself in her house. When she scrambled back up the stairs, he didn't know how he could bear to go upstairs and face her. But he decided it would be better to be done with it than live with the horrendous possibilities conjured by his conscience.
When he reached the top of the stairs, she was sitting composed at the kitchen table. "Adam," she said calmly, "can we talk?"
"Yes, ma'am," he said, and sank into a chair across from her.
"Don't call me ma'am. Adam, will you look at me?" He raised his eyes to hers and saw that she was not angry.
"Adam, I want to apologize. I had no right to walk into your room like that, and I'm sorry I violated your privacy. I hope I didn't embarrass you."
"You mean you're not mad?"
"Why would I be mad?" she asked. "Adam, you have nothing to be ashamed about."
"So you don't think it's wrong?"
"Adam, everyone masturbates. It's a natural part of being an adult."
"It is?" he asked.
"I do it."
His ears burned, and he could not return his eyes to hers. "You do?"
"My husband will be gone for two weeks. You think I can go that long without an orgasm? No thank you."
He trembled with excitement, and his cock was pressing against the fabric of his jeans. "That does make me feel better."
"Good," she replied. "I don't want you to feel any shame about the orgasms in this house, especially while it's just the two of us. I trust you, Adam, and I want you to trust me. It's the summer, and we should enjoy ourselves."
"That sounds great," he said, overwhelmed.
"Did you finish?" she asked, and he was stunned into silence. She winked and left to do the grocery shopping. He came in a huge spray of seed in the downstairs bathroom, a film of Denise Fuller with her hand stuffed down her panties playing in his head.

The next day was Tuesday, and he had the day off. He slept in after all the excitement from yesterday and didn't get up until he heard Denise out in the laundry room. The other disadvantage of staying in the basement was that the utility room was just outside. But it was already well into the morning, and time for him to rise.
When he stepped through the curtain, he stopped in amazement. Denise was facing away, sorting clothes for the washer, wearing only a pink negligee. Her arms and legs were bare, the skin tan and healthy from their time at the pool. The negligee was short, ending at the top of her thighs. He stood and stared, admiring the shape of her ass under the pink fabric. He averted his eyes when she opened the dryer and reached for the basket of clothes in the chair. Still facing away from him, she bent over to grab wet clothes from the basket. He was enraptured as her negligee rode up her thighs, higher and higher, until it exposed the sweet curves of her firm ass. Her cheeks were covered by lavender lace briefs, and as she bent further, he could make out the edge of her mound. His cock had hardened painfully inside his pajama pants.
She threw in the last of the clothes and slapped the door shut, turning around and jumping when she saw him. "You scared me," she declared.
"Sorry," he replied, standing with a tent in his pants.
