Jack's groin burned with arousal as he walked into his twenty-eight-year-old sister Irene's clothing store at the mall. His twenty-one-year-old cock was rock hard. All day at his job at the discount store, he couldn't take his mind off the hot fucking he and Irene would be enjoying in their new hideaway.
His erection was so noticeable throughout the day that Jen, his boss at the store, would leer at him, and in the midafternoon, called him into her office. She didn't have much to say, but while she prattled away at how pleased she was with his job performance, Jack couldn't help but notice Jen staring at his bulging groin.
Not that Jack was upset. Jack thought Jen was hot. She was around fifty with dark hair streaked with gray. Her legs were long and athletic and today, as always, they were nicely accentuated by skin-tight jeans. As much as Jack wanted to give in to Jen's barely concealed lust for him, he wanted to save his seed for Irene. He didn't even masturbate at all today, hoping to save up a huge blast of come for his sister's pussy.
Now, though, he was finally at his sister's store. Soon, his lust would be sated in the privacy of their hideaway.
It was just before closing time and the store was deserted. Even Kim, Irene's clerk, seemed to be gone. Irene was by herself at the back of the store, folding t-shirts.
As if Jack wasn't hard enough already, seeing his beautiful sister aroused him even further. Irene's back was turned to him. Her glorious chestnut brown hair cascaded past her shoulders. The tight-fitting black miniskirt she wore teasingly showed off the curves of her hips and ass. The slit at the side offered Jack a bit more titillation; the skirt was still classy and Irene looked hot in it, but it had just enough of a taste of sluttishness to make Jack's precome ooze.
Jack's eyes wandered down Irene's body, taking in a full inventory of his sister's sexiness. Irene's slightly parted, well toned and black stockinged legs were shapely and tantalizing; the golden bracelet around her left ankle drew Jack's eye to the black stiletto shoes that sensually displayed the curve of her feet.
Jack walked up beside her and eased the palm of his hand against Irene's ass. She jumped with shock, dropping the t-shirt she was holding onto the table.
Irene turned to face Jack and sighed. "Oh, it's you..."
Before she could say anything more, Jack pressed his mouth against his sister's, darting his tongue into hers, inhaling the pleasing scent of her sweet perfume. He snaked his arms around her waist, his hands roaming along her ass, pulling up the hem of her skirt. In the mirror behind her, Jack caught a glimpse of stocking tops, garters and buttocks cleaved by an elegant black thong.
He pulled her closer until Irene's D-cup breasts pressed against his chest, his tongue flicking over hers. Even through the fabric of her silk blouse and her bra, Jack felt his sister's nipples stiffening.
Jack's cock bulged in his tight jeans as Irene ran her palm along his crotch. She moaned and kissed him deeply again, then pulled her lips away.
Irene giggled. "It seems like you're ready for tonight."
"Yeah."
"Just go on to my office while I close up. I'll be back in a minute and then we can drive out to the place I found."
"Okay."
Jack limped a little as he went to the back room, his stiff cock mildly impeding his progress.
He sat down at Irene's desk and stared at the pictures on the wall of sexy catalog models sporting different styles of silk slips. He stroked his cock through his jeans as he savored the beauty of the models.
"Don't look at those girls. Look at me!" Irene was back, standing at the doorway of her office, hands on her hips and a frown on her face.
"Sorry, Irene."
"That's not enough. Don't you still want me, lover?"
Before Jack replied, Irene strutted up to him and sat on his lap, throwing her arms around his neck. She kissed him full on the mouth and Jack slithered his tongue into his sister's mouth again.
"That felt good," Jack moaned.
"Don't worry, lover. It'll get even better soon." She playfully wiggled her ass against Jack's groin. "Don't get too carried away. You've got to save up a big load for my pussy, my hot, wet porn slut pussy."
Irene's hands wandered up his thigh and reached between her ass and his groin.
He kissed Irene again, but she pulled away from him and rose to her feet. "Not so fast, lover. We've got to get out to our place right away. I'm practically dripping already, and you don't want my pussy to get all dirty, do you? You like your porn slut sister to at least pretend to be clean, don't you? Nice and clean and fresh just for you."
Jack nodded silently and rose to his feet and watched Irene as she pulled out her purse from a desk drawer. Even when she was doing this mundane task, she looked so sexy. Jack's eyes burned with passion as he stared relentlessly at his sister.
At last, Irene was ready to leave. She turned out the lights in the office and Jack followed her out to the shop floor, where the lights had already been dimmed. They came to the front entrance, where Irene had left the sliding door just enough for them to pass through to the atrium outside.
Irene quickly shut the sliding door completely and locked it.
"We're good to go," she said, bounding ahead of Jack. Jack was happy to linger behind his sister, admiring the way her ass and hips swayed as she walked.
Jack looked around and noticed there were still some guys left in the mall, older guys with graying hair who'd been hanging out at the coffee shop. Jack glanced at them as they headed for the main exit. Jack saw that they all discretely sneaked glances at Irene as she slinked out of the mall. Knowing that his sister was so attractive to other men and knowing that soon his cock would be in her dripping delta again, made Jack almost insane with arousal and hardened his cock to the point of fracture.
