Mark could only think about Lisa as he drove out of their gated community. She was the only person on his mind as he struggled to control the accelerator because of how his legs were trembling. Even the hand holding the steering wheel was slightly trembling; he could feel his arm tremble, but upon glancing at his arm, he could not see it actually tremble. Not yet, anyway. His right hand on Lisa’s thigh was still; there was no feeling that it was trembling.
In fact, as he continued driving, Mark moved his right hand upwards, the fingers pressing down against the denim fabric covering as it made its way down to her inner thigh at the same time. He heard Lisa give off a sigh before she parted her legs slightly, allowing his hand to reach down to the warm feeling between her legs. Upon reaching that warm valley, Mark pressed down into the denim covering her pussy lips. He heard Lisa go “Ummmmmmmmm!!!” and the passenger seat creak slightly as his fingers pressed down and caressed her covered pussy.
“Oh, Mark,” Lisa whispered with her eyes closed and her head resting against the head rest. “That feels good.” Coming to a stop at the traffic light, Mark pressed harder as he quickened his ‘come hither’ motions, using his fingers to press harder into the fabric just beneath her zipper. Even though his fingers weren’t penetrating her pussy lips, Mark could tell Lisa was enjoying it from the moans escaping her lips as well as her visibly trembling body. Even as cars came to stop on either side of his car, Mark’s fingers continued their motions. Lisa was moaning. “Yes, Mark, fuck… you are making me feel soooo good.” Licking his lips, Mark changed the motions made by his fingers–he was now drawing circles as he continued to press down.
“Haaaaaaaaa,” Lisa breathed out while her eyes, which were already closed, tightened shut as she slightly arched her back before taking in a deep breath. Mark glanced at his sister, who was panting hard as she adjusted herself on her seat while opening her eyes slowly towards him. He then glanced to her left and saw the driver–a middle-aged woman with red hair tied into a ponytail and wearing a suit–looking at him with a questioning expression. He smiled at the stranger before his eyes refocused on Lisa, whose eyes were once again closed, her head facing his direction.
“You are so beautiful,” Mark said. Lisa opened her eyes and gave him a smile that had his heart racing once again. Mark slid his hand away from her covered pussy and brought it back up to her thigh. He noticed the questioning expression on Lisa’s face, as if silently asking why he wasn’t continuing. Mark said, “Trust me, I would love to continue what I was doing, but…” He glanced at the woman in the other car, who was now staring out her own windscreen, and then refocused his gaze on his sister. “That lady in the other car was watching us.”
Lisa chuckled before she turned her head towards the passenger-side window and then stared at the woman who had been looking at them earlier. Lisa turned her head back towards Mark and smiled. “She’s no one we know.” Mark chuckled at Lisa just as the light turned green. Mark pressed down on the accelerator while thinking that Lisa was right; the woman was a stranger, and it didn’t matter if she had caught him ‘dry fingering’ his sister. Now, Mark wanted to just stop somewhere isolated and then take Lisa in the backseat, where she would be riding his cock to orgasm. He imagined carrying her out of the car and then bending her over the hood of the car and ramming in and out of her like an out-of-control piston.
As he drove, Mark’s imagination turned to Lisa screaming in pleasure as he fucked her on the field at the school stadium or on his bed, surrounded by people watching him take his sister. Mark could feel himself sweating as his thoughts raced–more scenarios being created in his mind, the subject of his thoughts being his sister. He could feel and hear himself breathing hard as he continued driving the car.
“Mark?” He returned to reality, his eyes on the traffic light having just turned red.
Mark came to a stop at the traffic light before turning his head towards Lisa, who was staring back at him with a quizzical expression. “You look tired.” Mark shook his head before turning his gaze down to the hand on her thigh. He then looked back up at Lisa and said, “Undo your zipper.” If he could not have sex with Lisa now, he might as well finger-fuck her properly. He hoped that would get Lisa out of his thoughts temporarily.
“Now?” Lisa chuckled before she looked around at the cars stopping around them. She then looked back in Mark’s direction and chuckled. “Mark, they could see us.”
“I’ll be careful,” Mark said as his hand travelled once again to the valley between her legs. “We have a few minutes stuck here, and… well, I want to see if you can stop bringing attention to yourself while we have some fun.”
“Really?” Lisa bit her lower lip before leaning back on her chair and then unbuttoning her jeans and pulling down her zipper. Mark stared at the pink-laced underwear Lisa was wearing while she placed her right hand on the door rest and her left hand on the back of the headrest. Mark slowly slipped his hand beneath her panties.
“Remember…” Mark whispered as he looked out the windscreen while his hand slid down until he could feel her hooded clitoral area and then the slit between her pussylips. Oh, fuck, was she wet.
Lisa gasped, her lips parting, as he inserted two fingers between her wet pussy lips. “…no movements, honey.” Lisa nodded her head while her eyes remained closed as Mark’s fingers moved expertly inside her as he applied pressure to her G-spot. Lisa’s breathing became more and more rapid, and she gripped the door rest harder with each passing moment. The feeling was incredible, and she wanted to scream in pleasure, but she remained silent, knowing that any erratic movement could get them caught by the drivers around them as they waited for the light to turn green. The effect of Mark’s ministrations was almost immediate; Lisa’s body began to shudder uncontrollably as she felt herself getting closer and closer to an explosive climax.
Lisa tightened her grip on the headrest and bit her lower lip, all the while feeling waves after waves of pleasure exploding from his fingers, caressing that most sensitive spot inside her cunt. She wanted to writhe on the seat; she wanted to grab her tits and squeeze them; and she wondered what it would be like to give the other drivers a show as she took off her shirt and bra before pulling her nipples and screaming for Mark to continue what he was doing. But even with the wonderful sensations going through her body, Lisa knew it would be a bad idea to give in to her imaginations–at least out here in public. She did know one thing: if Mark continued as he was with his fingers, she was going to orgasm hard. And in orgasming hard, she was going to squirt like last night.
Mark could only think about Lisa as he drove out of their gated community. She was the only person on his mind as he struggled to control the accelerator because of how his legs were trembling. Even the hand holding the steering wheel was slightly trembling; he could feel his arm tremble, but upon glancing at his arm, he could not see it actually tremble. Not yet, anyway.

Mark stared at the pink-laced underwear Lisa was wearing while she placed her right hand on the door rest and her left hand on the back of the headrest. Mark slowly slipped his hand beneath her panty.
“Remember…” Mark whispered as he looked out the windscreen while his hand slid down until he could feel her hooded clitoral area and then the slit between her pussylips. Oh, fuck, was she wet.

The effect of Mark’s ministrations was almost immediate; Lisa’s body began to shudder uncontrollably as she felt herself getting closer and closer to an explosive climax.
And Lisa didn’t want to get her panties and jeans wet. Not yet, anyway. Just as she was about to reach her climax, Lisa reached for Mark’s hand and pulled it out.
“Fuuuuuuuck…” Lisa groaned out as the massive orgasmic explosion awaiting on the horizon petered out to one that was something she would consider ‘Meh’. She still felt her body twitch; she was still enveloped in a wave of pleasure that went through her body as she held tightly onto Mark’s wrist. “Yeeeeessssssss,” she hissed before slowly opening her eyes just as Mark pressed the accelerator. She turned her head towards Mark, who had a small smile on his face, and then brought up his hand to her lips and put both fingers into her mouth. She could taste her pussy juices, which were slightly salty, as she used her tongue to gently lick his fingers. Lisa enjoyed watching him try to keep his attention on the road as she took his fingers out of her warm mouth. Lisa then explained, while still holding the hand that had gotten her off, “I was going to squirt, Mark.” She caressed his hand as she continued, “I can’t go to school wearing a wet pair of jeans.” Lisa placed his hand on her thigh once again before zipping up her fly with her right hand before continuing, “But after school…”
Lisa smiled at Mark as he turned the car onto the road leading to the school gates. “After school, after I get home, you and me…” She arched her eyebrow at Mark and licked her lips when he glanced at her. He held her hand before bringing it up to his nose. Lisa felt a shudder go through her body when he took in the scent of her sex that remained on his hand.
“You smell so good, Lisa,” he growled before taking a deep sniff before saying, “like the world’s most delicious honey pot.” He then kissed the top of her hand as he approached the gate, where there were already plenty of buses in the appropriate lane. There were also many groups of students already walking through the gate and into the school compound.
“Last chance, sis,” Mark said as he let go of her hand reluctantly, very reluctantly. “We could go back home right now…”
“I don’t want to repeat the year,” Lisa chuckled.
“It’s not that bad,” Mark replied with a grin, “repeating the year, I mean.”
Lisa giggled before saying, “You know what they say: good things come to those who wait.” She wanted to reach out and just brush her hand against the outline of Mark’s cock resting against his right leg. But Lisa was afraid someone from her class would recognise her, thus opening a huge can of worms.
Mark gave Lisa a pout before kissing her on the cheek. Oh, how he wanted to give in to his need to just take her in front of the whole school. Their lips brushed only slightly before he gave off a sigh of defeat and pulled back. Lisa chuckled before opening the door and then getting out of the car. Mark waved Lisa off before she turned and hurried through the gates and into the school compound. As she hurried up the pathway towards the main entrance, Mark noticed some of the guys and girls around her glancing at her at the same time. He noticed they took a deep breath before there was a look of longing on their faces as they watched her pass by them. It made him jealous; he could feel anger rising within him as his car slowly moved past the gate. He could see Lisa–her hips and ass swaying to and fro, calling out to him–as she walked further and further away. There were many people–students and some adults–looking at her as she passed by them. Stopping the car, Mark noticed some students had looks of confusion, others had looks of anger towards Lisa, and there were more heads turning towards her, but Mark couldn’t see their expressions from his vantage point.
Mark shook his head before starting to drive off once again. He whispered to himself that it was all in his head. Taking a deep breath as he imagined Lisa taking his already hard cock into her mouth, Mark drove carefully away. He needed to get some of the laundry done, especially the sheets in the master bedroom. He also needed to check on the damage done to the couch cushions: ‘I may need to get those dry cleaned.’ As Mark got back onto the main road, he imagined Lisa from last night and that very morning as she screamed in pleasure. He took in a deep breath before reminding himself that he also had to get to work before noon, “and after I get back…” He could already imagine the sex he and Lisa were going to have throughout the house.
Lisa could feel there was something a bit off about everyone around her. As she walked through the doors and into the school foyer, groups of students were already talking loudly among themselves as they mingled. Even as they spoke, Lisa noticed nearly all of them–at least those who were nearby–would turn their heads and stare at her as she walked past before returning to their conversation. Some had such looks of longing in their faces; others seemed to be angry at her. She thought some of those who were angry slightly twitched as she walked by; it was as if they were trying not to move their bodies towards her. It really was odd. And then there were some who seemed to have a look of fear as they gulped and stepped back when she strode past them. Lisa stared at them with a look of confusion before turning away and continuing on her way.
With the foyer and crowds now behind her, Lisa continued to pass many students who stared at her with a mixture of emotions before returning to what they were doing earlier. She turned into another hallway and then took the stairs to the second floor and entered a hallway where there were a row of lockers. As she neared her locker on that floor, Lisa looked back over her left shoulder at the students she had passed only seconds ago, who were once again talking among themselves. She could also see more students walking into the hallway through the staircase at the other end of the hallway. As she walked towards the row of lockers to her left, the reaction towards him was the same–there were a mixture of emotions as she walked past, and those reactions became muted after there was some distance between them. Lisa couldn’t help but think about the reaction of the bus passengers yesterday after school and wondered if there was a connection, and if so, what would that connection be? Lisa stopped at her locker, put in her combination for the lock, and then pulled the locker door open. She placed her backpack into the opening and then took out the required books for her first class.
