Becoming my Step-brother's Mistress

Chapter 5

"Are we there?" she asked.

"Behind the D-mart." Her head popped up. "Hey you're not done" he said.

"Let's go in before it gets too crowded."

"Finish what you started," he said firmly.

"It's almost six thirty she said, looking at his watch. I don't want to go in while it's busy in case someone notices me," she complained.

"Really Hollywood?"

"Please," she said.

"Ok fine, but you finish this when we get back," he said shoving his half-hard d**k into his jeans.

"Sure," she agreed, noticing the outline of his big d**k in his pants.

They walked from the back of the pharmacy to the front door and split up again. She assumed Merlin was looking for something to drink while she looked for the pill.

She looked across the 'Family Planning' section of the aisle, up and down, but couldn't find it. She swore under her breath. Then she made sure her sunglasses were in place as she approached a clerk filling the shelves.

"Excuse me, I can't find what I'm looking for."

"Ok what is it?"

"The uh... morning after pill," she said quietly.

The man nodded and took a scanning device from a loop on his belt.

"What's it called again?" He asked as he got off the ladder and walked towards Autumn.

"The morning after pill," she said clearly. "I don't know the name brand," she said, nervously scratching her collar bone. The older gentleman typed her description into the scanning device.

"There's a Next Day and Prevencia EC, do any of those sound right?"

"I'm not sure. Could you show me where they are in the store?"

"Sure, it's aisle 11," the man said, quickly walking her to the exact location. "Here's one," he said handing her a box labeled 'Next Day.' "And here's the alternative. Will one of these work?"

"Yes, thank you," Autumn replied, after seeing the words Emergency Contraception on the side of the box. She noticed Merlin approaching her with an energy drink.

"Looks like you got it?" he asked as the clerk walked off.

"Yeah," she said.

They walked silently to the front. The cashier wasn't there, so Merlin tapped a small bell on the counter. As they waited, Merlin locked eyes with Autumn and then he turned forward again to the counter. She started thinking about last night and how fast things had escalated to s*x. She'd never had an orgasm like that before and wondered if it was the size of his d**k, or something else like how he used it. His p***s curved a bit up in a way that she hadn't seen before either. Maybe that made a difference? Thinking about all these things, she realized that she shouldn't care exactly why s*x with Merlin felt so good. It was over now and she was going back to LA this afternoon. As the cashier walked up Autumn discreetly placed the box containing the single pill on the counter.

The woman scanned the morning after pill and the energy drink quickly and placed them in a plastic bag.

"Is this all?" she asked.

"No, one more thing," he said. "A box of..." he turned to Autumn. "What do you smoke?"

"Avi Lights," Autumn said.

"Avi Lights and a lighter," Merlin said.

The cashier got the box from behind the counter and scanned it.

"In the bag?"

"I'll take it," Autumn said. She placed it into her purse as Merlin placed his credit card in the slot.

"Ok that's sixty-eight, ninety-nine," the cashier said after totaling up all the items.

Merlin whistled in appreciation and Autumn winced. She was tired of being broke. She had just bought some Christmas presents a week ago (although most were for herself) and all of her accounts were locked. Although she was on a popular soap opera, she had a spending habit and shoes were her kryptonite.

After paying, they walked back towards the car. Merlin handed Autumn the bag after taking out the energy drink. Autumn removed the pill from the box and threw the container and bag into the dumpster. She waited at the passenger door of Merlin's car, but he lay back against the wall of the pharmacy on the other side of the car.

"What are you doing?" Autumn asked.

"Come here," Merlin said.

"Let's go back to the house," she replied, "And let me take a sip of your drink to wash this down," she said, indicating the pill in her hand.

"Not yet, come here first," Merlin said.

Autumn complied, walking around the car to where Merlin was standing.

"How about you finish what you started before you take this pill," he said, grabbing her hand that held the pill, and tapping on the bulge in his jeans with his other hand.

"Not here, someone could see."

The pharmacy faced the ocean with a front parking lot, but they were in a small area in the back with a couple parking spots labeled Facilities. Merlin's car was parked facing out, the back end a few inches from the structure between where Merlin was and a dumpster at the corner of the building. All they could see was a empty field of long dry grass.

"There's no one here. You should get to it," he smiled.

"Alright," she sighed, dropping the pill in his hand. She unbuckled and pulled down his pants. His c**k pushed forward, out of his pants, still half-hard. Merlin opened the energy drink with the pop-top as she held his d**k and wrapped her plump lips around the tip of his c**k.

She crouched in front of him so she would have as easier time fitting him inside her mouth.

As she pushed him deeper, Merlin pulled off her sunglasses, grabbed the back of her head and pushed further. She struggled against him and then broke free with a gasp as he set the shades on top of the car.

"Don't do that," she said.

"Come on you're a big girl you can take it."

"f**k you," she replied.

"Come on, be nice, you owe me."

"Just let me catch my breath."

"Fine," Merlin said, taking another drink.

She tried again and was able to fit a little more, but then she pulled back her head, fighting his hand that was pulling her closer. His d**k popped free from her lips.

"Damn girl, just a little more."

"You're too big," she complained.

"Don't give me that b***h. You know you can try harder."

Bastard, I should just bite it off, she thought briefly.

He was getting fully hard and now it was even more difficult to fit him inside her mouth.

She took a deep breath, and then, opening her mouth as wide as she could, descended onto his big c**k. Merlin pushed again and this time she was able to fit the head of his c**k completely and even a few more inches. Then she started to choke and immediately pulled her mouth off him, gasping for air.

"That's it," he grinned. "You got it in."

"I told you, don't force it. It's too big," she said.

"Ok, take your time then, but make it good," he said with a disappointed sigh.

Autumn put both hands to his d**k and pumped it as her lips went back and forth over the top of his c**k. She licked up and down, until his c**k was shining with her saliva.

Merlin squeezed her breasts over her low cut dress and strapless bra.

"Fuckin' big t**s," he said with a smirk.

Autumn shoved her mouth down again over his glistening meat.

"Hey pull these t**s out, I wanna see them wrap around my d**k," he said.

"You're keeping at eye out right?" She asked, looking around.

"Yeah, don't worry girl," he said.

She pushed her breasts up and out over the top of her strapless bra and dress.

"Nice, Tig ol bitties," He said, placing his c**k between her cleavage. He squeezed her breasts tightly over his d**k which thrusted hotly between them. "f**k that's beautiful."

She looked down at the tip of his c**k and as he pushed it up out of her cleavage she opened her mouth and allowed it to enter. She began to rub her breasts up and down his d**k while her mouth sucked the head. Her chest and neck felt flush as the contact of his d**k against her skin was driving her crazy with pleasure.

"Damn you got some great t**s Autumn."

"I know," she said, licking the underside of his c**k.

He moaned while staring down into her baby blue eyes.

Her feet arched in her knee-high boots began to cramp in that position, so she stood, his c**k falling from her breasts and mouth. Then she grabbed the base and sucked on the tip.

"Why'd you stand up?" he asked.

"My feet were hurting from sitting like that," she said.

"f**k that was great.. hmm, I have an idea," he said with a smile as he took another drink and set the bottle on top of the car. "Take off your coat."

"It's cold, what do you have in mind?"

"Just do it," he said.

She took off her coat and purse and he tossed them inside the car. Her pink n*****s were hard in the early morning air.

"Now come here," here said.

"What are you..-wait what?"

Merlin lifted her by the waist and twisted her body upside-down, so her legs were up in the air and her head was down, facing his hard d**k.

"Ah! You better not fuckin'drop me," she said.

"Don't worry," he said, holding her tightly against him. "Now you shouldn't have any foot problems."

Although her dress was form fitting, she imagined that her panties were on display in this position. Her legs were also supporting her weight, bent over his shoulders while she straddled his head.

"Don't you think someone will see now?" She said with a bit of anger in her voice. "Set me down now."

"How many people hang out behind a pharmacy this early? Come on, less talking and more sucking."

She could feel his warm breath against her crotch as she steadied herself against his waist with her hands. His long hard d**k stuck out, near her cheek as her face was pressed against him.

She leaned back and slowly licked across his big brown c**k from this new position.

Now that she had slowed down, and even though she was in a strange position, she almost preferred it. In fact, she was hardly surprised when she started to feel flush and warm as she let herself take as many inches as she could, the gentle upward curve of his c**k angling down her throat more easily.

"Damn that beer last night tasted like s**t," he said softly. "I better work out tomorrow, been drinking like a fish these past few days."

"Yeah you're getting fat," Autumn said with a smirk as she rubbed her hand up his chiseled lower abdominal muscles.

"You got a big mouth on you, huh? Why don't you use it to suck my balls instead of talk," he said.

She stuck out her tongue in rebuke even though he couldn't see her, but then cupped his balls and began licking one of them. The musk of his body filled her nostrils and fanned the fire in her groin. She found his smell almost intoxicating as she placed her lips around one of his balls, the size of an extra large egg and began sucking the fat testicle.

She sucked and licked over his balls while stroking his d**k with her hands. She felt Merlin's hot breath across her panties as she licked from his balls up to the head of his c**k, then tried placing her mouth over his d**k by opening as wide as she could muster. It squeezed against her teeth and she was able to fit the tip of his c**k into the back of her throat. She suppressed her gag reflex as she finally was able to properly fit him in her mouth.

"Oh yeah," Merlin moaned.

She stroked him with one hand as she deep-throated him. After pulling him out with a gasp, she circled her tongue around the head of his c**k.

"Damn that's more like it," he moaned

The warmth between her legs continued to grow. When she was going at her own pace she was definitely getting off on it. She took pride in her skills, but her stepbrother was the biggest challenge she'd ever faced.

She began to taste a small stream of precum from his c**k. Like an aperitif, the slightly sweet flavor stirred her desire.

She felt his hand on the back of her head as she bobbed up and down. Then she twirled her tongue under the head of his c**k again.

"Ah f**k," he said, in enjoyment.

She didn't want to admit it to him, but she really wanted him to f**k her again. As she felt her panties get wet, she hoped he would notice like the night before and try and f**k her. But she didn't want to seem too eager, otherwise she felt he would gain even more of the upper hand.
