"Mom, I need your help with something," Robbie turned the corner and walked into his mother's room.
Carla, his mother, was sitting in bed, reading a book like she always did at night. She was wearing the same nightgown she always wore. Nothing Robbie hadn't seen dozens of times before.
But this time Robbie paid attention to how his mother looked. For the last three days, his friends had been teasing him about his 'hot mom'. They knew her because she was a teacher at their school.
At first, Robbie had been annoyed by the teasing. His mother wasn't hot, she was just his mother. But now he wondered.
"Am I missing something?" he thought. "Do they know something I don't?"
So this time he really looked at his mother. Her favorite nightgown was see-through. He had never paid much attention to that fact before.
Robbie realized he could see her brown areolas moving up and down as she breathed. They were easy to see under the nightgown. He felt his cock stir in his pants.
She was looking at him, waiting for him to say something.
"You need help with something?" she prompted.
"Yeah," he broke out of his reverie. "I need to sew a button back on my shirt and I can't get this needle threaded. Can you try?"
His mother took the needle and thread. She raised her arm and turned, holding the needle up to the light so she could see better.
Robbie was watching her breasts. The nightgown shifted as his mother moved, showing him the outline of her breast. They weren't huge but they weren't small either. Robbie thought they looked soft.
For the first time, he noticed her nipple. It was a pretty ordinary nipple. Except that it was his mother's nipple.
He tried to subtly adjust his cock in his pants.
"What am I doing?" he wondered to himself. "It's just my mother. Just because the guys were kidding around about her being hot doesn't mean she is." His cock continued to disagree.
"Got it!" His mother handed back the needle, now threaded.
"Thanks, mom." Robbie paused for one last look before he left.
"Definitely not hot. Just average," he thought.
Carla smiled after he left. She knew he had been looking at her breasts. Frankly, she was surprised he hadn't done it years ago. But Robbie, now 18, often lived in his own world, lost in thought.
She had always worn see-through nightgowns. Carla had tried regular nightgowns. She found them too heavy. Her nighties were made of thin material and were light as a feather.
She had tried sleeping naked but could never get over the feeling someone would catch her. So she stuck with the see-through nightgowns.
Carla knew one day her son would notice. That day had finally arrived. Robbie's mother hoped it would be a phase that passed quickly, like a summer storm.
Her son had never seemed to have much interest in girls or sex. After all, he had never been on a date, never mind have a girlfriend. He had never even asked how to meet girls.
Back in his room, the boy focused on sewing the button back on. His mind kept replaying the scene in his mother's bedroom. Her breasts moving, the color of her areolas, her nipple sticking out. His cock kept getting harder.
He finished the sewing and went into the bathroom to jack off.
"This is so stupid," he thought "getting a boner over my mother."
That night he dreamed about his mother and woke with another boner. Morning boners were pretty common for him so he didn't think much of it. He jacked off and got ready for school
Later, Robbie was leaving the cafeteria headed for class. A friend passed him headed the other way.
"Just saw your hot mama," his friend said grinning and pointing back over his shoulder. Robbie saw his mother walking down the hall ahead of him.
Normally, he would have run up to say "Hi" but not today. Instead, he hung back, watching her hips move as she walked. He could see the panty line under her skirt.
"Does she wear panties to bed?" he wondered. His cock stirred and tried to rise in his pants. Robbie made a quick side trip to the boy's bathroom to shift it to a more comfortable position.
That night at dinner, they were eating and chatting as usual. His mother suddenly leaned forward to catch a bite as it slipped from her fork. Her blouse gaped open and Robbie was suddenly looking down at his mother's bra.
"That's a pretty skimpy bra," he thought. "I can see the top of her areola poking out."
The view disappeared as his mother sat straight again. Robbie looked closely at his mother's chest. Was he imagining it or was her nipple poking out? He shook his head to clear his mind and resumed eating.
Robbie was ready for bed but wanted something to drink. He walked to the kitchen, wearing only the lightweight flannel shorts he used for pajamas.
His mother was standing at the counter eating a piece of cake.
"God, he is a handsome hunk of beef, isn't he?" was her first reaction.
"Great minds think alike," she said out loud. "You want some cake?"
Robbie nodded. His mother was in her nightgown. The see-through one. And he could see everything through it. "Why have I never noticed this before?" he wondered.
His mother was wearing pink thong panties. He could see where her dark pubic hair shaded the pink. Some of her hair was visible at the sides. Looking carefully, Robbie thought he could see a camel toe.
"Is she doing this to tease me? Does she want me to make a move on her?" He dismissed the thought immediately. That was a crazy idea.
His mother looked at him oddly as he got his cake and began eating standing by the opposite counter. Robbie suddenly realized his cock was hard and his lightweight flannel shorts were doing nothing to hide it.
He shifted and leaned his side against the counter. That was even worse. His cock stuck out at a 60 degree angle, pushing the shorts away from his body. His mother chuckled to herself and politely looked away.
"I'm going back to bed," said his mother, still smiling. Robbie watched her hips sway as she walked down the hallway. The thong left her ass cheeks exposed. They jiggled as she walked.
"Damn, she's got a nice ass," he said half aloud.
Another dream about his mother. Another morning boner. Another jack off session.
Carla passed by the bathroom on her way to the kitchen. The door was open slightly. She knew he was masturbating. It wasn't the first time that had happened.
But this was the first time she looked. She peeked through the crack and saw her son with his cock in his hand. It was the first real cock she had seen in many years. Ever since Robbie's father had left.
"He sure is better hung than his father was," his mother thought. "Stop it! He's your son."
But she didn't stop watching. She was beginning to feel aroused. She kept watching until he was ready to come. Then Carla walked away.
"Leave him a little dignity," she thought.
At school, Robbie went out of his way to find his mother. He watched her walk down the hall. There was no panty line. Probably wearing the thong from last night.
Robbie thought about how her ass cheeks jiggled when she walked. He got erect. Robbie had already positioned his cock in his pants, knowing that would be his reaction.
During the same day, Carla was thinking about her son. Or at least about his cock.
Robbie's father had left over a decade before and Carla had put her sex drive on hold. She was busy with a job, a baby, and getting her teaching degree. She didn't have time for sex.
Besides men in their twenties didn't want to date a single mom when there were still lots of unattached women available.
Over the years, her sex drive had stayed on hold. Carla masturbated occasionally but it was less lust or desire and more a way to relax after a tough day at work.
The sight of a real cock, erect and in her own house, had set her sex drive back in motion.
"What is wrong with me? I've seen a cock before. Several of them, in fact. No big deal."
Her pussy seemed to disagree. It stayed wet all day. The longer she thought about it, the more she wanted sex. Or at least a hint of sex.
When she got home, Carla changed into her 'sexy bra' and an oversized shirt. She left an extra button undone.
"What harm can it do? It's just a little playful teasing," she tried to convince herself.
She made soup and sandwiches for dinner and placed her bowl a little further away than usual. Which meant Carla leaned forward a lot to eat her soup. Her loose fitting shirt fell open every time. Robbie could see both breasts.
"That's a different bra. It's skimpier than the other one," he observed. The cups were one layer of cloth with no padding. "I can almost see her nipple," the boy observed.
"Holy Shit!" The bra had just gaped open and exposed his mother's nipple. His cock was super hard. Then it did it again. Robbie rubbed himself under the table and almost came in his pants.
He hurriedly excused himself and hustled to the bathroom to masturbate. It didn't take long.
Carla smiled to herself. Earlier, she had installed a tiny webcam in the bathroom so she could record exactly what her son did.
"If he's going to jack off to me, I might as well jill off to him," she had decided.
Now she was amused. "He's getting all hot and bothered by my tits. Don't I feel like a fine sexy woman! Having an 18 year old drooling over my tits."
Robbie sat down again and focused on his mother's shirt. He paused his eating every time the shirt gaped open. About every third time, he could see his mother's nipple.
If Robbie hadn't been so focused on his mother's tits, he might have realized Carla's hand was rubbing her crotch under the table.
