Lustful Affairs (Erotica)

She was wearing a mid-thigh leather skirt that hugged her hips and flowed with the curve of her ass like a black velvet second skin. Justin trailed his eyes from her firm supple thighs down her tanned legs to the sky-blue painted toenails in open heels.

“Holy fucking God”, he whispered softly.

Katherine turned and looked at him, hearing the soft murmur.

“You’re beautiful”, Justin choked out.

“Thank you”, Katherine gave a shy smile as she walked past him to the front door. As she passed by him her voice barely above a whisper, hit Justin like a load of bricks. “And you’re hard”, she said laughed calmly.

Helping her climb into the truck again, he couldn’t tear his eyes from her. Katherine looked at him.

“Is my outfit too overboard?”, she asked.

“No, it’s fucking hot!”, Justin admitted.

They rode in silence in the growing dark until Justin could barely discern her tanned thighs next to him, but the image was burned into his brain from his continuous peeks when Katherine shifted in her seat or crossed her legs.

Picking the movie had been one of the easiest things Justin had done. He and his sister had almost the same likes and dislikes. He pulled into the theatre parking lot and found a spot. As he turned off the engine, Katherine reached out and gripped his hand in the dim light of the parking lot.

“We’ve always been honest with each other”, she said softly.

“Yes”, Justin said slowly, not sure where this was going.

“Are you still hard?”, he heard her ask in a small voice.

“Yes”. Justin couldn’t deny it, and she was right they had always been honest together.

“Why you still hard?” Katherine asked as she turned and looked at him.

“Don’t ask”, he choked out. “It’s wrong.”

“Is it because of my outfit?” Her voice sent a tremble through him.

“Yes”, he could barely speak the word.

Justin walked around the truck and opened the door. He extended his hand, but this time Katherine turned to full face him. As she prepared to slide out of the seat; her thighs parted. Justin couldn’t help himself; it was like a magnet pulling his eyes, and he glimpsed the color of purple lace between her firm thighs just as she started to slide towards him.

For the first hour of the movie Justin was in pure hell. He barely saw much of the show as every time Katherine crossed her firm muscular thighs, his eyes were drawn to her legs. When he glanced up his heart rate nearly doubled. Didn’t she only have two buttons open? He thought. Now three were undone and the top half of her breasts were clearly in view in the flickering light of the screen.

He had hoped that the distraction of the movie would help his raging hard cock subside. Instead, it was the opposite. He lost track of how many times her fingers gripped his arm; and once, she reached out and gripped his thigh only inches below his groin. The constant contact and the sight of her exposed flesh kept a steady flow of blood pumping into his engorged cock.Belonging © NôvelDram/a.Org.

Finally, he couldn’t stand the tension and suspense. The words of his father rang in his ear; you could always blame it on the dark, he thought. He reached out and took a drink of his soda; replacing it in the holder, instead of resting his hand on the armrest, he let his hand drift to the side and let it come to rest on the smooth skin of Katherine’s thigh.

For a brief second, he felt her tense under his touch; and then she relaxed. He had expected her to yell at him, but her face stayed locked to the screen. He was more shocked when she made no attempt to stop him as his hand slowly drifted over her thigh.

Her skin was warm and soft under his fingers; and Justin marveled at how smooth her legs were. He began to explore the length and width of all that bare skin; each inch sending more blood into his already painful hard cock. When his hand bumped the edge of her skirt, Katherine reached down and gripped his wrist.

Oh God, she’s going to tell me to stop, Justin thought. Instead, he was shocked by her soft words.

“What color are they?”, Katherine asked in a soft whisper, while her eyes never left the screen.

Justin knew then she had seen him peeking when she got out of the truck. His immediate reaction was to deny and to claim ignorance. But it was the thought they had always been close that changed his mind.

“Purple… lace”, he whispered back.

Justin was further shocked when she slowly released his wrist but did not move his hand away. Instead, she lifted her hand and rested it on her arm rest at her side. When he didn’t move his hand for a moment, in rabid fear, Katherine gently parted her thighs, inviting him in.

Sliding higher Justin found the edge of her now drenched panties, amazed at how much moisture clung to her thighs and seeped through the cloth. God, she’s a fucking swamp he realized. He slid his middle finger up the crease of her thin panties, until he found the hard bud of her clit. He began rubbing it lightly.

“Unngggggghhhhhhhhhhhh”, Katherine gave out a low guttural moan.

Justin continued to tease and pleasure that hard bud. Her breasts rose and fell as her breathing became even more labored. Finally, she turned and looked at him, a fire glinting in her eyes.

“If you don’t put your finger inside me right now, I swear to God I’ll scream” her voice low and husky.

Justin knew what they were doing was wrong. It was not only culturally illegal, but morally wrong. And if his parents ever found out, he would be disowned. It didn’t matter at that moment, as he saw the sheer pleasure on Katherine’s face. Katherine pulled her soaked panties aside. Extending his middle finger, he watched her face as it slid between her soaked lips and into her steaming depth.

Her knuckles turned white as she gripped the arms of her chair; her mouth opened in a silent moan and her eyes fluttered. Without moving his arm, Justin gently pumped his fingers in and out, moving slowly to hide the sloshing of her wet pussy. Katherine rested her head on his arm, and her orgasm hit. He watched as her body began to tremble.

After she finished, she gasped softly, “No man has ever… touched me… like that. Until now, Jess is the only one who ever made me orgasm.”

Justin could feel warm juices flowing over his hand. She reached down and gripped his wrist, slowly pulling his finger free. She stared at the fluids that clung to his finger is amazement.

Katherine brought her wet fingers to my nose. The scent was intoxicating. I opened my mouth, and she stuck them in. The taste was more intoxicating.

Justin wasn’t sure what was going to happen. It’s not every day you sit in a dark movie theater and finger your sister to a mind-numbing orgasm. But Katherine quietly rearranged her clothing and seating. She reached out and twined her fingers in his and they sat and watched the remainder of the movie.

Through the rest of the movie and quiet drive back to Jess’s place, one thought kept invading Justin’s mind. After they had pulled into the driveway he turned to his sister.

“Listen, if I invaded you in anyway…”, he started to say.

“You didn’t”, Katherine turned to face him.

“I mean… you mentioned you and Jess, and I didn’t want to…” Justin tried to explain.

“Look”, Katherine reached out and rested one hand on his thigh. “Jess and I have explored, I’m not going to lie”, she smiled. “But she is as much into guys as she is girls”, Katherine chuckled.

“Oh; I thought maybe you two were… you know”, Justin looked over at her.

“Lover’s?”, she asked. “Look Justin, Jess’s bi-sexual. And me… well I wasn’t sure.” She sighed.

“Wasn’t sure about what?” Justin asked.

“I thought maybe I might be gay.” Justin felt her other hand slide onto his lap as he stared into her eyes. “I’m not; no guy attempted to do that to me… until now.”

Justin shuddered as he felt her fingers deftly unsnap his jeans and begin to draw his zipper down.

“Kat… you don’t have to…” he tried to protest.

“I know I don’t have to”, she dipped her hand through the opening of his boxers. “I want to”, she purred as her hand wrapped around his hardening cock.

“I’ve never done this before”, she husked. “So, tell me what to do.”

His cock was hard as steel. “Put your mouth around the head, and swirl your tongue around it.”, Justin instructed her. He just sat and watched as Katherine’s head lowered between his stomach and the steering wheel. He couldn’t see through the mass of dark hair; and with only the dim porch light, there wasn’t much to see. But God, he could feel it.

Wet warm surrounded the head of his cock, and he felt her tongue slowly making circles.

“Oh Goddddddd”, Justin moaned.

He reached out with both hands and gripped the steering wheel, as he felt his sisters hot mouth slide down his cock. He looked around in fear, God if anyone saw what was happening it could get back to their folks.

“Oh shit… Kat”, he moaned as her mouth began to move up and down. The sound of her sucking filled the cab as she devoured his throbbing dick. “I think you got this!!”

Justin could feel his balls tightening. If this was her first blowjob, he couldn’t imagine what she could do with experience. He moved one hand down and curled his fingers in her dark hair. Glancing over, he was shocked to see Jess standing at the door to the house watching them. There was no way she could miss the bobbing mass of hair in his lap. Jess gave me a thumbs up, and slipped back into the house. He knew then there was only one way this was going to end.

“Oh fuck… Kat… that’s so fucking good.”, He gasped!

Justin felt her mouth come free and her muffled words from his lap.

“Am I doing that good?”, Katherine questioned a little out of breath.

“Keep it up and you’ll make me cum”, he warned her.

“Good”, was her one word reply and then that heat wrapped around him again.

“Oh shit… don’t stop… oh fuck Kat…”, Justin babbled as his nuts tightened until they ached.

“Oh my Goddddddddddddddddd” he moaned as his body jerked; and the first blast of hot cream pumped into her mouth.

He heard her softly gag on the first blast; followed by the sound of her swallowing as he fired off a second and third blast.

“Mmmmmmmmmmmm”, Katherine murmured as he unloaded his balls into her eager mouth.

Justin’s brain spun with sheer pleasure as his sister drank his hot seed. He never came like that. EVER!!! Part of it was the forbidden aspect of Katherine being his sister. And part of it was also how soft and gentle she was.

By the time Katherine lifted her mouth from his softening cock, she had managed to suck out what felt like was every drop of cum his balls had held. He just stared in wonder as she rose back to sitting, a small dribble of white goo trickling from the corner of her mouth.

“Holy shit”, Justin breathed out slowly.

Katherine reached up and used the tip of her finger to swipe at the small glob, popping it into her mouth. She smiled at Justin.

“Now that was hot”, she murmured.

Justin couldn’t move as Katherine opened her door and slid from the truck. He tucked his limp cock back into his jeans as he watched her walk to the door. This was simply going too far, he realized. He needed to rethink this arrangement, but for tonight he just wanted to remember the hottest blowjob of his life.

For the next three days, Justin thought and pondered over where things were going with Katherine. It was a route he had never intended; and one that both troubled and excited him. She made him feel in ways he had never felt before; but the nagging thought this was his sister kept bubbling to the surface. Finally, just when he thought he had worked up the nerve to talk to her; Katherine floored him once again.

Coming home from working second shift, everyone in the house was sleeping and Justin quietly picked his way through the darkness to his room. Closing the door, he flipped on the light and then he stepped to his desk to drop his keys. Sitting on his desk was the hundred dollars he had given Katherine for being his prom date. It was resting on a note.

His heart sank as he picked up the hundred, and then the note. She was calling it off, he thought. No prom… While his dad would be pissed off, he knew she was right. Then he looked down at the note.

‘I want to do this because I choose too, not because you paid me.’

As Katherine’s words sank in, Justin wasn’t sure whether he was scared of what might come next or thrilled his dad would get off his back if it did.

For the next week, his father kept going on and on about the upcoming prom and Justin’s date. Every time he bragged about ‘his boy’ bagging some hot high school girl, Katherine would just stare at him and then shake her head. It was so bad his father gave him money for a tuxedo, and bought him a fresh box of condoms, which he flaunted at the dinner table making Justin blush as Katherine looked on.

On prom night, he was in Jess’s house waiting for Katherine to get ready.

He heard her coming down around the corner of the hall. His first sight was red painted toes in a pair of strapped high heels. As she came closer, his eyes traveled up her calves and lower legs, to the expanse of firm tanned thighs. The hem of her rose dress ended just above mid-thigh, low enough to be proper, but high enough to create the threat if she bent or moved wrong.

By two more steps, he didn’t know which way to look. That firm ass that the skirt flowed over. Or the taut belly clearly visible through the rose lace of her top. It was so sheer; Justin could see the glint of silver from her belly button piercing.

But it was when she got to him, he almost stopped breathing. The rose lace continued up and over the curve of her breasts. The sheerness highlighting the globes of flesh they barely hid; the dress had just enough thickness at the right two spots to hide the caps of breasts, taking the nipples from his view. There was no bra, he realized. The top was tied in a single bow at her neck; and the back, well, there wasn’t one. Bare tanned skin ran the full length down to just barely above the crack of her ass. It was apparent she also had no panties.

“You can breathe now”, Jess’s amused voice sounded in his ear.

“Oh my God”, Justin let out with his held breathe. Katherine looked at him in surprise. “You’re stunning”, he said more softly.

“Thank you”, Katherine gave a demure smile. “Shall we?”, she asked softly.

All through the drive Justin couldn’t tear his eyes from her; he was still in shock at how stunning this tomboy sister he had never noticed was. It didn’t help that the obvious tent in his slacks showed his approval. Katherine said nothing as he kept stealing glances; she just sat quietly with her hands in her lap.
