Billy Turns Tables on Step Sister Ch. 04

Emily and Carla sat on the front porch sipping iced tea and watching Billy mow the lawn. Watching Billy work up a sweat was quickly becoming a favorite pastime of the two women. At thirty seven, Emily has had a marked increase in her sex drive. She was basically out of control, and Billy was only too happy to administer to her needs. Without even realizing it, Emily had slipped a hand down her shorts and was pressing two of her fingers against her clit as she watched her stepson work.

Carla glanced down and saw what her mother was up to. She giggled and rolled her eyes.

"Mom, you really are unbelievable," she said.

"What?"

Carla raised her eyebrow and made a show of looking down at what Emily was doing with her hand.

"Oh. I didn't even realize I was doing that," giggled Emily.

"He really has turned you into a complete slut, hasn't he mom?"

Emily smiled at her daughter. "Listen to the pot calling the kettle black. You were so loud begging to be fucked last night that the neighbors must have called the police."

"That was a problem because we woke you?"

"No honey. That was a problem because you didn't invite me to join you," admonished Emily.

In the months since Billy had first fucked Emily, the relationships between the three of them had morphed completely. Both of the women had fallen in love with Billy, and he with them. The women loved each other as well. Emily no longer thought of Billy as a boy. She saw him as a man, and he had taken over the household. No major decisions were made without her first consulting with Billy. They engaged in some light bondage and discipline, and it thrilled Emily beyond words to have her stepson spank her ass with his bare hand. Billy ruled the roost, and the two women could not be more satisfied with that.

The more Emily watched Billy work as she pressed her fingers against her clit, the needier she became. Watching her brother was having a similar effect on Carla, and she started to rub her own pussy through her shorts. The women were cut short when Billy stopped the mower and walked towards the porch.

"It's hot out here. Would one of you beautiful ladies get me a glass of iced tea," asked Billy.

Carla got out of her seat and walked toward the door. "Sure little brother," she said as she glanced over her shoulder at him. She wiggled her ass flirtatiously as she walked into the house.

Billy sat on the arm of Emily's chair as he waited for Carla.

"You are just a joy to watch," Emily said hoarsely. She reached her face up to his neck and ran her tongue from his collar bone to his ear, tasting his salty sweat and lightly biting his earlobe. "I was touching myself while I watched you, and now I'm all wet and throbbing. You want to take a break, honey?"

Billy's reply was to grab Emily by the hair and tilt her head back, kissing her deeply. By the time Carla came out with Billy's drink, Emily was topless and sitting on Billy's lap.

"I can't leave you two alone for a second, can I," said Carla as she sat down and watched them kiss and fondle each other.

Emily was purring and grinding herself against the bulge in Billy's shorts. She wanted more, so she got up and started for the door.

"Time to go inside for a while."

Billy and Carla grabbed each other's hand and followed Emily into the house. The two women worked together to undo Billy's shorts and pull them down and off. He stood there naked except for his sneakers. Emily was on her knees with his cock in her mouth, and Carla stood beside him kissing him and running her hands all over his body. After a few minutes, the women switched positions. Emily was kissing Billy with extra fervor.

"What's gotten into you today, mom?"

"I think I'm going to get my period. That always makes me horny as hell. God, I need your cock inside me, Billy," said Emily. "I need you to fuck my brains out. I've had enough foreplay."

Carla pulled Billy's cock from her mouth and looked up at her mother with a raised eyebrow. "Wow mom. You are unbelievable today. It's like your cunt is on fire," she teased.

"It is, Carla. Let me have him for a couple minutes, honey. You go after me."

"Sure mom. I'll sit back and watch. I love watching Billy fuck."

Billy got onto the floor flat on his back. He pulled down a pillow from the couch and put it under his head. He watched as Emily straddled him and reached down, guiding his big cock into her bare cunt. Emily closed her eyes and sank all the way down on it, resting a hand on her abdomen as if she could feel him inside her. She loved how deep Billy could fill her. She opened her eyes and looked down at her stepson. She was his, and his alone. Emily started riding Billy, biting her bottom lip and staring into his eyes.

"God Billy. When you fill me like this...I swear...I wish you were fucking me pregnant. I'm swollen and ripe, and...ohhhh. Fuck." Just talking about it made Emily lean forward and cum, kissing Billy wildly. Billy had her by the hair and was kissing her back, and he was thrusting hard up inside her. Carla was leaning against the couch with her legs spread rubbing her clit as she watched.

"Fuck. That would be so hot, Billy. Watching you fuck mom and getting her pregnant. Knowing that you knocked up my mom with that big fat cock of yours. Knowing that you own her. And me. I would be next Billy. Both of us. Pregnant by you. Your bitches. Your..."Carla trailed off as her orgasm hit. She threw her head back and squirmed around, moaning loudly.

Billy heard it all and took it all in, thrusting harder and deeper into Emily until he finally succumbed and filled her with stream after stream of his cum, grunting and moaning the entire time. Emily collapsed onto his chest, petting his face and neck with her hand. She stayed there until his cock softened and slipped out of her, finally moving with a great deal of reluctance.

Carla crawled over and took Billy's cock into her mouth. She liked to start sucking him when he was not yet hard, so she could feel all of him in her mouth before he fully stiffened and would no longer fit. She could taste her mother on Billy's cock, and she liked it. It didn't take Billy long to become fully erect again. Carla rolled onto her back, and Billy got between her legs. He pulled her legs up onto his shoulders and filled his sister's cunt with his meat.

"Fuck me good, little brother. Fuck your slut of a sister, Billy. Tame me with your cock. Please. I need your taming," Carla begged.

Billy was pounding into his sister. She breathlessly whispered "fuck me" with every stroke of his cock until she could no longer speak. She was clinging onto him for dear life, and when Billy thrust into her and came, she too came wildly, biting into his shoulder, scratching his back and pulling his hair.

The three of them wrapped around each other and dozed for a while, with Billy awakening first midafternoon. He got up and headed into the bathroom to pee. When he came back out, Carla was sitting on the couch and Emily was in the kitchen, starting to make lunch for them. Billy loved how they looked after he had fucked them. He thought there was nothing sexier than their hair all messed up and their faces all red and chafed by his beard.

Emily brought a tray of sandwiches and three glasses of iced tea over to the couch. Billy grabbed a roast beef wrap and took a bite, looking at his mother and sister.

"That was pretty damned hot," he said.

Emily looked at him and blushed a bit. "Yeah. Billy...I was just talking, Billy. I..."

"You were serious, Mom. I could see it in your eyes. The thought of me making you pregnant turns you the fuck on. Big time."

"Billy..."

"I want you to tell me the truth, Mom."

"Okay. Yes. It's really hot to think about. It makes me cum every time. Okay?"

Billy gave her an evil grin. "I've been thinking about it myself lately, so it's funny you brought it up today."

"Billy, being a turn on is one thing. Bringing a child into this world is another."

"Are you saying you don't want to have any more children," Billy asked.

Emily sighed. "Billy. I didn't say that."

"So, you'd like to have another baby?"

"Billy!"

Carla was eating and watching the exchange, and she could see Emily's resolve beginning to weaken. Holy crap, she thought. My brother really IS going to get my mom pregnant.

Billy continued with his questions. "I asked you a question, Mom. Do you want to have another baby?"

Emily looked Billy in the eye. "Yes. Okay? Yes I do. I want to have another baby. But I'm just about divorced. I don't want to be a single mom at thirty eight years old."

"In case you haven't noticed, we are a family here Mom. The three of us. We are together."

"Billy, you're eighteen. Carla is twenty one. I'm thirty seven. How long do you think this is going to go on?"

"You are both my women, Mom. You always will be. You understand that, don't you?"

Emily blushed as she felt her cunt clench with his words. Carla was grinning ear to ear, happy to hear how Billy felt. Emily looked down at the floor, then up at Billy. "Yes," she whispered. "I understand."

"I love you both. Do you understand that?"

"Yes. I love you too, Billy. But..."

Billy put a finger to her lips.

He took a last bite of his sandwich and sat back on the couch, sipping his iced tea. He looked at the women with an air of authority of a man much older than eighteen.

"Mom gets pregnant first," he said. "I don't want you both pregnant at the same time." He turned towards Emily. "Go get me your birth control pills, Mom. We start now."

Emily opened her mouth to say something, then thought better of it. Her heart was pounding, and every beat echoed in her now throbbing pussy. Deep inside, there was nothing more she wanted this moment than to have this beautiful young man impregnate her and be the father of her child. She went into the bedroom, returning a minute later with the pack of pills. She handed them to Billy, biting her lip and staring into his eyes.

"Do you think you can maybe finish the lawn later? I really need you to fuck me again, Billy."

Billy nodded and looked at Carla.

"Go, go," she said, shooing them into the bedroom. "Oh my God. I'm going to be an aunt and a sister at the same time," she squealed.

Carla cleaned up the remnants of lunch as she listened to the sounds of Billy fucking her mother in the next room. She was smiling and humming to herself as she worked. When she was finished, she fell onto the couch and used her fingers to bring herself to several orgasms.

Within a few weeks, Emily was ovulating. To say that the atmosphere in the house was sexually charged was an understatement. Billy fucked Emily relentlessly, and Emily couldn't get enough. Both of them tended to Carla's needs as well, making sure she didn't feel left out. There was little surprise but much joy a few weeks later when Emily came out of the bathroom with a smile on her face, holding up the pregnancy test stick.

"I hope you know what you're doing, Billy. You've gotten me pregnant. You've gotten your mom pregnant."

Billy was sitting in a chair in the living room, and Emily dropped to the floor in front of him and opened his shorts. His cock was at half-mast and growing rapidly, and Emily wasted no time using her mouth to please her son. Billy held her head in place as he filled her mouth with his cum, and Emily gobbled down every bit.

Emily's tummy began to grow, and the bigger it got, the hornier she got. It seemed to affect Carla in the same way, and it was all Billy could do to keep up with the two women. Emily had gotten very fond of licking Carla's pussy, bringing her daughter to orgasm after orgasm. Billy was thoroughly enjoying Emily's body as it grew. He was particularly enamored with her tits, which seem to have grown at least two cup sizes. He asked Carla to film him and Emily as he fucked her from behind, her huge, swollen tits swaying with each stroke, her tummy plump and full of his child. It was an interesting nine months to say the least.

They were the talk of the delivery room when the nurses finally got their hands around who was who. Both Billy and Carla were present at the delivery. A groggy Emily looked up at Billy as he held their son, and she wondered how anyone could love a man more than she did at that moment. As she drifted off to sleep, Billy and Carla left the room to go home and get some sleep of their own.

Carla hooked her arm around her brother's as they walked, and leaned her head onto his shoulder.

"When will you take my pills from me, Billy? You promised I was next," Carla said as they walked through the maternity ward. The head nurse popped her head up with an incredulous look on her face as she heard this. Billy looked at her with a smile and a shrug, and headed out the door with his sister.
