Jack and Jill Worth have been married for twenty years and have an eighteen-year-old son, Bob. They live a comfortable life in a split-level house located in a suburban community. Jill is thirty-nine and has maintained the figure she had when she got married. She’s dedicated her life to making Jack and Bob happy and healthy. Part of her daily routine is exercising at the gym, early every morning. Jack, on the other hand, never exercises and has a mentally demanding job. Over the past five years, he has become a workaholic. It started with him working ten-hour days; now, he’s often putting in twelve to fourteen-hour days at the office.

They used to have an active sex life three or four times a week. It has tapered off over the same period of time and is now every four to six weeks. Jill is sexually frustrated, resorting to using her fingers and toys. She’s starting to wonder, “Does he have some cute, young, thing at the office?”

Bob recently graduated high school and is attending a local Community College. He is living at home with his parents and has never had a girlfriend. For that matter, he doesn’t have any close male friends either. You could say that he’s a loner, more interested in his studies and his hobby, reading porn on the internet and masturbating.

One afternoon, while she’s taking Bob’s clean laundry to his room, Jill hears him moaning as she approaches his door. She knows that sound; it’s sexual ecstasy. Standing there listening to him, Jill immediately feels her pussy get wet. She slowly opens his door just a crack and sees him lying on his bed. He’s pumping his hand up and down his cock. “My God,” she thinks, “who knew he has at least eight inches of thick cock. I need to find a way to use it to satisfy me.”

Jill quietly closes his door and puts his laundry down. She goes to her bedroom, grabs an enormous dildo, and pumps it in and out of her drenched pussy until she has a massive orgasm. After she recovers, she goes to the kitchen and starts preparing to cook supper. As she does that, she thinks, “His desktop monitor was on, I wonder if he was watching porn.” She finishes her preparations and cooks supper for the two of them, knowing that Jack won’t be there to eat with them.

An hour later, supper is ready, and she calls, “Bob, come eat supper.”

He comes down to the kitchen and gives her a peck on the cheek, saying, “Thanks Mom.”

“You’re welcome, honey,” she replies, giving him a brief hug.

They sit at the table, and while eating, Jill asks, “How was your day? Anything interesting happen?”

He answers, “We had an interesting discussion in my Human Relations class today.”

“What was it about,” she asks.

“I don’t think you’d be interested,” he replies, red-faced.

“Don’t be embarrassed. I’m not a prude, you know,” Jill says.

Still red-faced and looking at his plate, he replies, “It was about the percentage of families that incest occurs in.”

“Really? Is it a high number?” she asks.

Bob’s cock is hard and getting uncomfortable. He reaches under the table and adjusts himself. Jill notices and thinks, “This conversation is turning him on.”

“It’s higher than most people think, almost twenty percent,” he replies.

“That’s higher than what I thought it would be. I was thinking maybe ten percent. Did you learn any other facts in that class?” Jill asks.

“Most of it occurs between siblings, with only about ten percent between adults and children and three percent between other relatives,” he replies, clearly getting uncomfortable with the direction of the conversation. Bob says to himself, “What’s going on? Mom’s never been this interested in my courses before.”

Jill then asks, “Did they break down the parent-child incest?”

“They didn’t have an exact breakdown but the study suggested that father-daughter incest was more common than mother-son,” he replied. “Mom, can we talk about something else? I’m really uncomfortable discussing this with you.”

“Okay Honey, we’ll drop the subject. I was just curious,” she says.

She thinks, “I wonder why he doesn’t want to discuss this. I need to see what kind of porn he’s watching.”

They finish eating, and Bob helps her clean up the kitchen. When done, they go into the den to watch TV for a few hours.

Around 9 pm, Jack comes home, pops his head into the den, and says, “Sorry I wasn’t here for supper, we’re backed up with work. Are there any left-overs from supper?”

“In the ‘fridge, “Jill responds coldly.

Jack goes to the kitchen, gets the plate out of the ‘fridge, and reheats it. He eats then joins Jill and Bob in the den.

An hour later, Jack says, “I’m tired. I’m going to bed.”

He gets up and goes to their bedroom. Ten minutes later, he’s snoring.

Back in the den, Jill looks at Bob and says, “I’m getting tired and you have an early class tomorrow. I’m going to bed and you should too.”

“Okay Mom. I want to see the end of this program then I’ll go to sleep. Goodnight.”

“Goodnight, honey,” she responds.

Jill is sitting at the table, drinking coffee, when Bob comes into the kitchen at 8 am.

She asks, “Want some cereal and coffee before you head for your classes?”

“Just some coffee, I’ll get something at the doughnut shop on the way,” he replies as he gets a cup out of a cabinet, adding, “I have to work a shift after class, I’ll be home around 6.”

“What would you like for supper?” she asks.

“If you’ll prepare some hamburger patties, I’ll cook them on the grill,” he states.

“Sounds good,” she replies, “I’ll make a salad to go with them.”

He finishes his coffee, heads for the door, and says, “That sounds great. Love you, Mom.” as he leaves.

She pours another cup of coffee and sits there, thinking, “He’s taking over more and more of a man’s duties around the house. He already fixes things, now he’s grilling. I wonder what he’ll do next?”

Then she remembers what she saw yesterday afternoon and thinks, “I need to see what he was watching.”

She takes her coffee, goes up to his room, sits at his desk, and turns on his computer. She opens a browser and brings up the browsing history.

To her surprise, she sees that most of the porn involves moms and sons. “Hmm, that’s why he was uncomfortable talking about that class, yesterday,” she thinks.

As she reads down the list of porn, she thinks, “With a cock like his, I can kill two birds with one stone; make his fantasy come true and I can get my sexual needs met.”

She closes the browser and turns the computer off. Taking her coffee cup, she returns to the kitchen. She refills the cup and starts planning how to seduce Bob.

Her first thought is, “I need to show him more of my body without being too obvious.”

She decides from now on; she’d be wearing a nightgown when he came to the kitchen in the morning. She also chooses to wear sexier clothes, instead of jeans and T-shirts, to better show off her figure. She goes to the master bedroom, changes to go out, then goes to the mall. While there, she enters one store and buys several low-cut, translucent blouses and a few pairs of very lightweight slacks. When satisfied with those purchases, she walks through the mall to Victoria”s Secret. Entering, she goes directly to the bra and panty sets. She’s never worn a thong before and decides it’s time. She picks out five sets of thongs with a skimpy bra then starts browsing the negligee. She picks out two that are very low-cut. She takes it all to the register.

The girl looks at Jill, then at the purchases, then back at Jill. “I don’t know who you’re after, but you’ve got the figure and now have the clothes to catch him,” she says.

Jill smiles and says, “I hope so.”

She leaves the mall and returns home. She prepares the hamburger patties, then makes a salad and puts everything in the ‘fridge. At 5 pm, she takes a shower then puts on a new red bra and panty set and a new cream-colored blouse and white slacks. Jill walks over to the full-length mirror and inspects her choice of clothing. The red bra is visible under her translucent blouse. She thinks, “This should turn him on.”

Promptly at 6, Bob comes home and quietly walks to the kitchen. Jill is there with her back to the entrance. He stops and stares at her as his cock gets hard. She turns and jumps, startled.
