Carla got out of bed and padded toward the kitchen to get dinner started. She was naked. Her body felt relaxed for the first time in weeks. Her mind was at ease.
Carla and Robbie had had sex once before, weeks ago. Carla almost immediately regretted it. She tried hard to stop it from happening again. Weeks of frustration for her and her son.
Carla's resolve had finally broken down. She had pressed her son's head against her pussy and said, "Make me cum". She had given him a blow job and swallowed his cum. She had mounted him and taken his cum inside her.
Robbie had made her cum. Three times. Twice with his tongue. Once with his cock.
All that happened just a few minutes ago. That was why she was so relaxed.
"That was so fucking good," Carla thought. "I hope it's that good the next time."
She didn't usually swear but this was a special occasion. She pumped her fist. She was full of cum and happy as a lark.
Robbie had cum three times also. Once jacking off, once in his mother's mouth, and the last one inside her pussy. She had sprayed his cum on her face and tits. There was still a little bit above her eyebrow.
Robbie was almost as happy as his mother.
Robbie followed his mother to the kitchen. Carla watched his soft cock bounce as he walked.
"He really does have a pretty cock," she thought. "I think I like sucking his cock even better than fucking."
Her mouth began to water and she knelt down to take her son's cock in her mouth again. Even teenage boys have limits on how much sex they can take but Robbie hadn't reached his limit yet. His cock got hard and he thrust forward, hitting the back of his mother's throat.
"My mother is kind of a slut," he thought with a smile. It was a new and interesting revelation for the boy. He didn't quite know what to do about it.
Carla's Sensible Self rose from the dead. "You just fucked him not ten minutes ago. Finish him off and go fix dinner. We're all hungry."
Her Sensible Self was sensible enough to know Carla was going to continue having sex with her son. It had given up trying to prevent that. But there were still practical matters to consider, like fixing dinner and going to work tomorrow.
"You can't just have sex all day long," Sensible Self pointed out.
"Why not?" Lustful Self pouted.
"Because people need to eat and sleep and work," Sensible Self replied.
Lustful Self and Sensible Self came to a compromise. Sex with Robbie would continue but there would be some limits so that normal life could continue also.
During the discussion inside Carla's head, Robbie had cum in his mother's mouth. She had swallowed it and cleaned off his cock.
"What if you get pregnant? I came inside you," Robbie asked, worried.
"It would be great if I got pregnant," his mother dreamily thought.
"Not to worry," she said. "I just had my period. I won't be fertile for a while."
Robbie looked confused by her answer. Sex Ed had been three years before and had been his worst subject. Carla promised to explain 'the birds and the bees' again later.
"Would it be so terrible if I got pregnant?" Carla asked. She hadn't really thought about what Robbie might want.
"Wouldn't it mess up your job? Do they allow teachers to get pregnant who aren't married?"
Carla laughed. "Some places would have a problem with it, I guess. But not our school. There are already a couple teachers who had children without being married."
That included her lesbian friend, Linda, the English teacher. Linda had used a sperm donor to get pregnant.
"But what about you? Would you be upset if I got pregnant?" Carla needed to know how Robbie felt.
"I guess not. But I don't know anything about babies." He was clearly concerned. His mind was in turmoil as he thought about it more.
"What if I get a girlfriend? What if I get a job somewhere else? What if I want to travel?" Robbie blurted out. "Am I going to be stuck here with a baby all my life?"
"Relax, honey," Carla touched his cheek to soothe him. "I don't expect you to be the daddy. You just be a good big brother and live your life. I raised one baby by myself. I can raise another."
"I raised a big boy and his big toy," she smiled as she touched his soft penis.
She felt his cock stir and turned away. Dinner first. 18 year old boys may be able to have sex all day and all night but middle aged women couldn't.
Carla opened the refrigerator and got some things out. She bent over to get fixings for a salad and felt Robbie's finger enter her pussy from behind. She slapped his hand away.
"Listen, buddy, you can't just feel me up every time you get the urge." Her tone was sharp and she was angry.
"That's not how you treat women. Even women you have slept with. You don't just grab and poke like she's a piece of meat." Carla stood with hands on hips, glaring.
Running through her mind was Robbie's father, her no good ex-husband. A man who thought all women were his for the taking. He had forced Carla to do things she didn't want to do. He had refused Carla when she did want to do things. Then he left.
"Robbie is not going to turn out to be scum like his father," she swore to herself.
Robbie was stunned. He hadn't meant to make his mother angry. He was also confused. One minute he's shoving his cock down her throat and the next he can't touch her.
"I'm sorry," he said quietly. "I guess I don't know how all this sex stuff is supposed to work."
Carla gave him a hug and calmed him down. "We'll talk about how to treat women the right way later. For now, just don't be grabby."
Carla fixed a salad and steak. She reheated leftover mashed potatoes. She considered reheating the leftover corn on the cob but decided not to.
"If I took that corn and put butter on it, I bet it would slip right inside my VaJayJay. Nature's dildo." Where did that thought come from? Having sex with her son had really triggered something inside her.
Dinner was ready. Carla told Robbie to fix the plates and go to the table. She went back to her room for a minute.
Robbie was sitting down when his mother returned. She was wearing her blouse and skirt again. Except the blouse was barely buttoned and she wasn't wearing a bra.
"Sometimes it's more fun to get a peek than to have everything hanging out," she advised.
Carla made sure to lean forward frequently so Robbie could look down her blouse and see her bare tits. It had the desired effect. By the time he finished his salad, Robbie was stroking his cock. Before he was halfway through dinner, he stood up to go to the bathroom.
