Jack's drowsy eyes flickered open and stayed open. There was that sweeping sound again; as if his bedroom door were opening and brushing against the carpet.
He glanced nervously around the room as he lay in his bed. Once again, as he had in the two months since he had last seen his sister Irene, he had left his computer on, the browser left open at a web page showing one of the many pictures of Irene's large bare breasts he had uploaded to an erotic networking site he liked to visit.
The eerie pale glow of the monitor filled his bedroom. It revealed to him a silhouette moving from the bedroom door and creeping slowly toward his bed. What the hell? Was this a burglar?
Jack's heart raced with fear and sweat broke out on his forehead as the silhouette drew nearer. Should he leap from the bed and confront the intruder? No, he would wait. See what the intruder did and then take action.
The silhouette passed in front of the monitor and the stranger immediately became familiar - very familiar.
Irene!
Jack's heart almost stopped with shock and he wanted to cry out as he watched his sister slip out of what seemed to be shorts and a tank top. Taking no time to tease, she unhooked her bra, stepped out of her thong and slipped into the bed beside him. Jack's elation grew as Irene pressed her shapely twenty-eight-year-old body against his nude and recumbent twenty-one-year-old form.
His hands roamed freely down Irene's waist and feverishly encompassed her ass as her hands reached for his groin. Instantly Jack's cock stiffened in his sister's sure and practiced clasp.
He wanted to moan, but her free hand covered his mouth.
A husky voice whispered in the darkness. "Relax, lover. I'm right here with you. Lie back and I'll take care of you..."
She straddled him, her knees firmly planted on either side of his hips. Her palms pressed down on Jack's bare, muscular chest as she slowly lowered herself over his erect manhood.
Jack raised his hips to meet her downward thrust and soon they movements met in a powerful rhythm. Bed springs creaked as their passion slipped the bonds of restraint. Jack's breathing quickened and he struggled to stay silent as his greedy hands squeezed Irene's bouncing D-cup breasts. He had to keep quiet. Dad was away on a business trip, but Mom was asleep just down the hall. What if she woke up? Why the hell was Irene doing this if she knew Mom was here...
The fear of discovery aroused Jack further and his passion grew as his eyes made out in the bedroom's half-darkness the outlines of Irene's stiff nipples.
Jack could hold back no longer. He thrust with ever growing force into his sister's moist yet clenching womanhood. His balls, ripe with seed, tightened under an almost unbearable weight and with a barely stifled grunt, he drained stream after stream of hot jizz inside Irene.
Irene collapsed on top of him and he kissed her hard again and again on her mouth.
They held each other tightly as Jack's withdrew from Irene and their passion cooled.
Jack shivered with pleasure as Irene gently caressed his face, wiping away the beads of sweat. She whispered in his ear, "I've got the night free tonight, lover. Stu's going out drinking with his friends. Meet me at the store at six, then we'll go to our hiding place, okay?" She kissed Jack again, this time on the mouth. She had more to say. Just hearing her voice made Jack's cock stiffen. "I love fucking you, lover. I'm marrying Stu in less than a year, but it's your cock I think about when he fucks me. It's your jizz I think of when he comes inside me. I can't get enough of your big, thick, beautiful cock, lover, and I can't wait until tonight when I can feel it deep inside me again. See you soon."
Jack moaned softly as Irene squeezed his cock and balls one last time and then rose from the bed. She pulled her clothing back on, and with a quick kiss on Jack's cheek, she drifted wraith-like from the room.
As the gray light of dawn glowed in the window, Jack eased back into the warm embrace of sleep.
It had all been a dream, hadn't it?

The memory of his early morning encounter with Irene haunted Jack even as he stacked shelves with handful after handful of tuna tins. Had Irene really sneaked into his room? Should he really visit her at the store at six? It must've been a dream.
"How you doing Jack?"
Jack spun on his heel and he saw Jen, his boss. Jen was in her fifties, yet Jack found her extremely attractive. She had long, slightly graying black hair and a slender, athletic build. Today, she was dressed slightly more provocatively than usual. She wore a white blouse and a blue denim wraparound miniskirt that accentuated the curves of her hips and her shapely bare legs.
Jack forced himself not to look at Jen's tempting body. He made eye contact with her and regretted it immediately. Her brown eyes burned with lust and stared relentlessly into his. He glanced away from her as she spoke.
"Jack, I need to see you."
She was trying to seduce him again. Jack wasn't in the mood, especially with what had been happening - or seemed to be happening - that morning with Irene. His voice was cold, dismissive. "You've already done two performance reviews on me in the past week and a half."
"Jack I need to see you."
"I've got shelves to stack."
Jen's voice grew icy, threatening. "I'm your boss Jack, and if I want to see you, you have no choice but to obey. Do you understand?"
Reluctantly, Jack set the tuna tins in their boxes and he followed Jen up the aisle toward her office at the rear of the store.
As much as he hated fighting off Jen's advances, Jack had to admit to himself that he enjoyed walking behind her. He thought Jen's rear view wasn't nearly as impressive as Irene's but it was good enough and as much as he tried to fight it, Jack grew hard in his tight jeans as he watched his boss's large, shapely ass sway as she walked.
Soon, they were inside the privacy of Jen's office.
"There are performance issues I have to discuss with you Jack. Or, should I say, lack of performance issues."
Jack could barely contain a smirk as Jen spoke. He hoped he didn't sound too sarcastic as he said, "What do you mean? I'm not stacking enough shelves? If you ever let me out of this damn office, I could stack shelves like you wouldn't believe."
"That's not the kind of performance I'm thinking of Jack. Let me demonstrate what I mean."
