Becoming my Step-brother's Mistress

Chapter 4

When she awoke, Autumn's nether regions felt sore and wet with a sticky substance oozing out. The odor was unmistakable and immediately brought feelings of dread. She had slept with her step-brother only a few hours ago and the product of that encounter was seeping out. Her uneasiness wasn't because the s*x was bad, but because she feared a pregnancy in her future.

The uncomfortable feeling in these early morning hours prevented her from falling back to sleep, so she decided to roll out of bed and check her smartphone. She found a pharmacy nearby and although it was only five thirty in the morning it was already open. She left the room where her biological brother Adonis was sleeping on the twin bed across from her. He hadn't woken when she had come back to the room last night, and she was grateful for it. She didn't plan on telling him or anyone else in her family what had happened with her stepbrother.

The house her mother and stepfather were renting for Thanksgiving had three bedrooms, but only two bathrooms, so she had to walk quietly downstairs in a lacey nightgown, a hairdryer in one hand and change of clothes in the other.

She sighed when the warm water of the shower hit her back. She washed away all of the c*m she could as it dripped onto the tiles of the shower floor. Some of it had dried against her leg like a layer of crispy fish scales that she flaked off with a loofah. She finished rinsing the shampoo from her hair, and after scrubbing her shapely hourglass figure clean with the loofah and soap, she turned off the shower.

She wrapped a towel around herself and used the hairdryer to blow out all the moisture from her golden blonde locks. When she was finished, she put on the clothing she had brought to the bathroom, pink low-rise panties, a rose colored off the shoulder bodycon pencil length sweater dress, with a strapless pink bra beneath, a pair of high heel knee length leather boots, and her white wool coat. She looked quite sexy, but also very fashionable, she thought with a smile.

When she finished, she walked upstairs to the end of the hall where the other bedroom was. As she approached slowly, she looked down the hall in the opposite direction before peering into the room with the slightly open door.

Her step-brother Merlin lay face down on a full-sized bed, his toes hanging off the edge of the mattress. The sheet only covered part of his legs, the rest of his light brown skin was bare. Autumn took another look down the hall before she entered the room and closed the door behind her. She looked down at Merlin's fit body, her eyes lingering on his round muscular butt.

"Merlin," she said softly. There was no response. She spoke louder and tapped his shoulder gently, but he still didn't wake up. She said his name a third time and pushed his shoulder back and forth.

"Uh," he moaned. He stirred, his eyes opening. "Hey," he said. "What time is it?"

"About six."

"f**k, what do you want?" he asked, his eyes closing again, still lying face down.

"Do you have a car? Can you take me somewhere?" She asked.

"Why?" he replied.

"I need to go to the pharmacy," she said, as she folded her arms below her breasts with a stern expression.

"Huh? What are you talking about?" he replied. "Right f*****g now?" he asked. He flipped over, his big c**k and balls slapped against his leg. Autumn's eyes were immediately drawn to his large genitals. She blinked quickly and then looked back at his face. He was rubbing the sleep out of his eyes.

"Umm.. could you cover up?" she asked, rolling her eyes and, pointing to his crotch.

He chuckled, and smiled but didn't comply. "Can't you Uber or something?"

"No. I tried yesterday, but there's something wrong with my account."

"Why the pharmacy?"

"Please?" she begged. Merlin lay back on the pillow and closed his eyes.

"What's the big emergency?" he asked.

"Last night...," she struggled for words as she looked at his limp c**k again. "Remember... you didn't use a condom, and you... came inside me."

"Yeah..?" he said, slightly opening his eyes. "I warned you." She tried to keep her eyes on his face, holding a hand up to shield his genitals from view.

"I'm not on contraception, so I need to go get the morning after pill."

"I'm really tired," he said, closing his eyes with a yawn. "Why don't you ask Ashton?"

"Adonis," she said crossly. "And no way, I don't want him to know about what happened," she said, her voice level rising.

"Why aren't you on the pill?"

"That's none of your business."

"If you are going to be fuckin' random d**k you should be on the pill."

"I..." she sighed angrily. "I don't take it because I gain weight when I'm on it. Please drive me to the pharmacy, unless you want to be paying child support?"

"I'm sure your rich parents can manage, why don't you ask your mom for a ride?"

"You want mom and your dad to know? And if my...boyfriend... found out that I slept with someone else... let alone my stepbrother he'd... I just need that morning after pill. I could pay you later. Or maybe..."she paused.

"Or?" he said, arching his eyebrows.

"Well, no I mean... like..." she sighed. "Is there something you want?" she said with a wince. He grinned. "Not... not s*x again," she said. "Last night was... a mistake. We shouldn't have..."

He stared straight in her eyes and she became silent.

"I guess I'll have to think of something," he said getting out of bed. Autumn turned, so she wasn't looking at his naked body. Last night was so dark that she couldn't see how toned his body was, but the morning light shining through the window left nothing to the imagination. If there was an ounce of fat on his body, she couldn't see it. It was difficult to explain, but the fact that he was so hot almost annoyed her.

"Uh, I'll wait downstairs for you."

"Wait a second, I just gotta get my pants on," he said. "Could you hand them to me? They're right by the door."

She grabbed them, the belt still looped in, and held her hand over her eyes as she handed the pants to her stepbrother. She only saw a little through her fingers, his curly pubes and the defined veins of his lower abs. She felt his large hand briefly on hers.

"Ok," he said a few seconds later. She lifted her hand, watching as he grabbed a shirt from his bag and pulled it over his head. "You sure it's open this early?" he asked.

"Yeah I checked online."

"Ok, I'll take a piss and then we can go," Merlin said, pulling on socks and shoes. They walked downstairs to the bathroom and Autumn waited outside, in the hall, for her stepbrother. The sounds of his urination seemed loud and long until she finally heard a flush and the sink as he washed his hands.

"Ok let's go."

Autumn noticed that the sky was overcast and the air was cold as they entered Merlin's car and he started the vehicle.

"Where's this pharmacy?"

"ACG pharmacy: turn left and it's on the corner a mile down on the right," she said as she looked at her phone directions.

"Ok," he yawned. Merlin plugged in his phone and began playing Indy music through the car stereo before he pulled onto the Pacific Coast Highway. Autumn took a pair of large black sunglasses from her purse and placed them over her eyes.

They drove without talking, which Autumn didn't mind, because she didn't have much in common with her step-brother anyway.

When they arrived at the pharmacy, he parked in the nearly empty parking lot and turned off the car.

"Ok, hurry up," he said. "I think I figured out how you can repay me."

"How?"

"I'll let you know when you get back."

"No, you have to come with me."

"Why?" he asked.

"My credit card isn't working. That's why I can't Uber."

"Now you really owe me," he said. They both left the car and walked inside the pharmacy. Autumn's large black sunglasses were still over her eyes.

"I'm going to get something to drink," Merlin said, leaving her to stand alone in the front entrance briefly.

"Welcome to ACG," an employee in a green vest said. Autumn looked down at the floor, avoiding eye contact and immediately went to the 'Family Planning' section. If only he had put on a condom, she thought.

When she couldn't find what she was looking for, she went to one of the clerks and asked for the morning after pill.

"We don't have that," the older woman said.

"Do you know if another store would have it?"

"No," she replied flatly.

"Thank you very much. You've been very helpful," Autumn said, her tone dripping with sarcasm.

Autumn started looking for Merlin and found him peering through a glass refrigerator door which he opened as she approached.

"Where is it?" Merlin asked.

"We have to go to a different pharmacy, they don't have it."

"Ok let's go," Merlin said with a sigh, closing the refrigerator.

Autumn pulled out her cell phone from her purse and called another store as they walked to the car. She was able to confirm a pharmacy that had the pill before she hung up.

"D-Mart has it it. Just drive a couple blocks farther down the highway next to the Choco Grill."

Merlin nodded as he started the car. Then he unzipped his pants and pulled out his d**k.

"What? " she said.

"This is how you're going to pay me back."

"I said no sex."

"Just suck me off."

"But..."

"I can always go back to the house," Merlin replied.

"No, I'll do it," she said with a sigh. She grabbed his big brown c**k which felt warm against her skin. She looked back and forth on the road out of Merlin's tinted windows, seeing if any cars were near them. Satisfied she wouldn't be noticed, she put her head down, her mouth enveloping the tip of his soft d**k.

"Yeah, that's it," Merlin smiled. He pulled the car back on the road and started driving towards where she had indicated.

She began to stroke him, while he pushed against the back of her head.

"It's too big."

"You don't need to stroke my ego, just my d**k," he said, pushing her sunglasses up onto her forehead.

She licked from the base to the tip of his c**k and then all around the head.

"Not bad," he moaned.

She could feel him getting harder as she stroked him. She pulled away and looked up at his face while she pumped his caramel-colored meat in her hand.

"You said D-mart right?" he asked.

"Uh, yeah," she replied. She noticed he was looking down at her. "Hey, pay attention to the road," she said, his c**k popping from her mouth.

"b***h, pay attention to that c**k," he retorted, pushing her head onto it. The car bounced a bit as he drove, and after turning again he parked the car, shutting off the engine. Autumn's lips kissed up and down his big brown sausage, as the subtle flavour of his d**k entertained her tongue. She looked up at his hazel eyes, with her baby blues, and then pulled his d**k from her mouth.
