My Solo Shift Surprise

I've been working night shifts for months now at this industrial warehouse. Usually it's just me and a few machines until three AM when the rest of my crew comes in, but last week I had to cover an extra shift with everyone off sick. It was dark and quiet by midnight when I heard something unusual, whispered voices outside the loading bay door. My heart raced as I realized someone was trying to slip inside unnoticed. With a mix of fear and thrill, I unlocked the door cautiously. Two figures stepped in quickly: a man and a woman, both dressed all in black. They looked relieved but nervous. The woman whispered they needed a place for their private rendezvous away from prying eyes. Without hesitation or much thought, I agreed. The moment we were safely behind closed doors, the tension broke into passion. She leaned against one of the massive steel pillars while he approached her slowly, his hands exploring her body hungrily through her thin shirt. They moved together in the dim light, undressing each other quickly and precisely. He knelt down between her legs, spreading them wide as she moaned softly, her fingers digging into his hair. I couldn’t help but watch from my perch behind a stack of crates, fascination overcoming discomfort or any sense of propriety I might have had. She was slick with arousal, gasping and whispering endearments to him despite our proximity. They moved like practiced lovers, knowing exactly what each touch meant for them both in that moment. The raw need between them was palpable, driving me closer to my own climax just from witnessing it. After a while, as the intensity of their passion subsided into quiet pleasure, they slipped back on clothes and thanked me again with quick nods before slipping out the way they came in. Alone once more, I felt an unexpected surge of heat between my legs. My night had taken an unexpected turn but it was hard to feel regret as I cleaned up the mess left behind and finished my shift with a contented mind.
