Becoming my Step-brother's Mistress

Chapter 6

She moved back to his balls and sucked each one loudly, before licking her way back to the tip and filling her mouth with as much c**k as she could.

"f**k yeah," he said enthusiastically. "You keep at it like that, I'm just about there."

She continued to stroke his c**k with her hands and suck the head, only slowing slightly as she tried to ignore her p***y, throbbing and moist with anticipation.

She let his c**k pop out of her mouth and licked the underside, beneath his piss-hole.

"Oh f**k," he moaned. "Hold on." He turned her, and lowered her onto her feet. "You ready to taste it?" He asked, stroking his d**k as she stood in front of him.

"Not in my mouth."

He took the pill from his pocket and held it out so she could see it.

"Not much of a choice. Open wide." She did as she was told, squatting down as he placed the pill onto her tongue. "I'm going to wash that s**t down, and you gotta swallow it all," he said as he held her hair and jerked himself in front of her lips. "Uh," he moaned as his d**k pulsed. The first burst shot across her tongue and carried the pill down her throat as she gulped it down. The taste was better than she remembered, but it had been several years since she'd swallowed. The consistency of his semen was a bit like yogurt. He pumped his c**k again and again, filling her mouth with loads of his cream that she kept swallowing until about the fourth which didn't go down so easy. She spit it onto the asphalt.

"Almost took it all," he said.

"I don't usually swallow," she explained.

She sat up and wiped her lips with the back of her hand. She looked around the parking lot.

"Don't worry, no one saw," he said encouragingly. She bent back down, looking in the side mirror to check if any of his spunk was on her face. She was half disappointed that it hasn't led to something else, but it was for the best. Even now, her p***y was tingling with almost Pavlovian anticipation. But now they could go back to the house and get on with their lives. She stared at her face in the mirror again and frowned. Her face felt flush, her n*****s hard, and her p***y pulsed softly. She didn't think she had ever gotten horny for a guy by only sucking him off. It was very annoying, she thought.

"Thanks for the pill," she said dryly. "Let's go back." She cleaned up her eye-shadow in the mirror.

"Sure," he said and suddenly she felt his hand grab her ass.

"What are you doing?" she asked as he pushed her towards the car with his body.

"I gotta get in this p***y one more time. You don't mind right?"

She smiled, as he pulled her wet pink panties down around her ankles. Her p***y was on fire, eager to have him plunge inside of her again. She flipped her hair to one side as she looked back at him with desire. Then, she remembered where they were.

"Uh.. not here," she protested, turning back towards him. "We're gonna get caught if we keep going at it."

"No one's gonna see," he argued, pushing her hip back, so she was facing the car again. She looked out over the top of his sedan to the next building, about half a block away, which was the back of a small restaurant. Someone in a white smock left the business through the back and threw something into the restaurant dumpster before going back inside. Merlin's car was obscuring the view from the restaurant and the pharmacy dumpster behind them obscured any view from the other building.

Although she doubted anyone would see them directly, she was still very concerned about being caught in the act. Especially considering her rising celebrity, but she didn't raise anymore objections as Merlin pulled her dress up around her waist.

Still a little sore from yesterday, but who's knows when's the next time I'm going to get f****d this good? she thought as he began pressing the tip of his c**k to her slick opening.

"That's what I like, already wet," he chuckled softly.

"Uh..." she moaned. "How are your still hard? Didn't you just c*m?"

"Most mornings I can c*m twice." he said. She wasn't sure if he intended to boast, but she was nonetheless impressed.

"Oh god," she said, as his c**k slid deep into her p***y. The feeling of his long brown d**k was amazing and she could already sense the proximity of an orgasm as if she only had to reach out and touch it. He lifted one of her legs by the crook of her knee and grunted as he thrust into her wet p***y. Her loud moan punctuated the mostly quiet morning save for the morning traffic on the other side of the building.

His hips moved forward and back, driving his large d**k deeper with each thrust, until it pressed against her back wall.

"Oh my god," she moaned.

"There it is," he said. "Damn your p***y feels good."

He dropped her leg down and continued his relentless assault on her p***y, as her juices ran slowly down her inner thigh.

She closed her eyes, Merlin pressing against the small of her back with his thumbs, as he held her small waist firmly. She let go of her concerns and worries, and just let herself enjoy the throbbing d**k that was f*****g her.

"Ah," she moaned.

She held herself against the car with her forearms, pushing back against his plunging c**k.

"That ass," he said, obviously enjoying the view of her backside.

"Ahh," she cried, as she felt him slap one side of her large and desirable derriere.

A moment later he slapped again, to the other side.

He kept thrusting harder and faster until she felt her naked breasts flattened against the cold glass window of the passenger side.

Although her n*****s were hard with the cold window, her p***y was very warm and nearing release. Each orgasm she had felt with Merlin had been more intense than any she had with previous boyfriend's or by herself. Up until yesterday she only had a vaginal orgasm twice. She usually had to rely on her boyfriend's c*********s, which was decent, but the orgasms with Merlin felt wanton, almost primal.

"Yes, yes, oh my God," she cried, as a powerful orgasm washed over her body. She nearly collapsed against the car as her knees buckled, but Merlin held her up. Although she had no idea how long it lasted, the orgasm felt like it lasted almost two minutes, and all while Merlin held his c**k in place, deep inside while Autumn's p***y was squeezing against it powerfully.

Autumn sighed as the last throes of the orgasm subsided.

"f**k," she said with a sigh. In the moment she didn't seem to regret anything.

"Not done yet," Merlin said. His c**k popped free from her p***y as he turned her around to face him. "Come'ere," he said, grabbing her butt and lifting her up.

"Whoa," she said with concern as she wrapped her legs around him and put her arms across his muscular neck for support.

"Hold tight," he said, moving one arm at a time beneath her ass so she was sitting on his open hands. Each of her legs were bent at the knee over the crook of his arms so that he could lift her up and down easily.

The top length of his rock hard d**k pressed up against the crack of her ass.

Merlin lifted Autumn slowly, his d**k trailing along the cleavage of her ass until she felt it move beneath her and she was looking down at Merlin's face.

"Grab that d**k and get it in there," he ordered.

She reached down with one of her hands and moved his c**k like a joystick until it pressed firmly to her slick opening. Having found purchase, he lowered her down, his c**k burrowing deep until she felt his c**k press against her back wall.

"Oh my god," she cried out. Her face was less than an inch from his, and their eyes locked as she was impaled on his big d**k.

In this position she felt more of his hard length than she had ever before.

He started moving her up and down his c**k with his muscular arms. She didn't know how long he could maintain this activity, but she thoroughly enjoyed being f****d this way. She tossed her hair back as she held him around the neck.

"Kiss me," she panted. She tilted her head down to his lips and his hips didn't slow as they kissed. At this point, instead of lifting her up and down, he held her in place while he thrust against her, their tongues pressing passionately in her mouth while his d**k brushed firmly across her g-spot.

Suddenly she felt her body tensing as an another orgasm quickly overtook her ability to reason. She pulled her head back from his lips, moaning loudly in extacy. Her face and chest felt hot as her p***y quaked across his d**k and her body began to shake involuntarily. The feeling of his plunging c**k was pure pleasure. The orgasm seemed to last minutes, but again, it was difficult for her to judge time at a moment like this.

"Oh yeah, keep squeezing that d**k babe," he said, "You ready to swallow some more?"

"Come inside," she panted. "I already took the pill."

"Ok, f**k it," he said, setting her upper back against the car while held her legs against him. His hips floated back and forth, as he entered her nearly completely.

"Ahh," she winced as his c**k slammed against her back wall. His hard thrusts reached a tipping point until...

"Here it comes," Merlin said. She felt his thick seed deep inside her, as the burst of his semen coated her inner walls. He thrust a few more times, the amount diminishing with each thrust until he was finished, and his head collapsed against her neck.

He set Autumn down suddenly, and then lay back against the car.

She looked into her step-brother's eyes as he breathed heavily, and then looked down to his d**k which had begun to droop.

"Gonna just rest here for a bit," Merlin said with heavy breaths.

"No problem, you earned it," she said with a wan smile.

"Before we go, she said, "let's have a smoke."

"Yeah," Merlin agreed. Autumn went to the car and pulled out the box of cigarettes and lighter from her purse.

"Let me open 'em while you do that," Merlin said, noticing she was pulling up her dress, trying to get her breasts back in place.

"Ok," she replied.

As he tapped the box against the palm of his hand, she pulled up her pink panties from the ground. Noticing they had become dirty from their short time there, she tossed them behind the passenger seat. She pushed her large breasts into her strapless bra as Merlin unwrapped the box and pulled out a couple of cigarettes. While he lit them between his lips, Autumn pulled the tight dress back up over her bra and pulled the hem of her dress down.

Merlin passed one cigarette to her and they smoked silently, enjoying the reprieve.

Unexpectedly, the cashier came from around the corner of the pharmacy, carrying a bag of trash.

"You can't be back here smoking," the woman said as she approached the dumpster.

"We were just leaving," Merlin replied, quickly opening the door to the car as he dropped the cigarette on the ground and snuffed it out beneath his shoe. Autumn placed her sunglasses over her eyes and got in the other side.

"I'll call the cops to report you," the cashier said threateningly.

Merlin pulled out of the parking lot and onto the highway as Autumn rolled down the window, holding her cigarette perched along the outside of the door.

"Feels like I'm back in High School," she said with a laugh.

"Yeah."

"So Merlin," Autumn said, as she took a drag from her cigarette. "How did you learn to f**k like that?"

"Lots of practice," Merlin laughed.

Autumn shook her head at her step-brother's cockiness, but still smiled as she enjoyed the early morning air.

"Hopefully they're all still sleeping when we get back."

"And if they're not?" Merlin said.

"Hmm..." she mused, taking a drag of the cigarette, and blowing a plume of smoke out of the car window. "I guess we tell them the truth."

"Really?" Merlin said with surprise.

"Yeah, we went out for cigarettes."

"Right," he chuckled.
