She hated working the late shift. She sat at her desk, her office all locked up to be safe, until 2am just in case there were any emergencies. It was a dreary Monday evening, the complex absolutely silent, as the last person had gone home about half an hour before, so when her phone rang, it gave her quite a fright.
"Are you on late shift this week?" he asked her without preamble when she answered.
She confirmed that she was.
"Good." He replied "I'm outside. Open the door."
She went to let him in, trembling with excitement. She knew what he wanted. She wanted it just as badly.
She opened the door and let him in, locking it behind him.
She turned to face him, to find him staring at her with undisguised lust in his eyes. With a small growl in the back of his throat, he pushed her against the door and started to kiss her.
She moaned softly as his mouth and tongue started working on hers more urgently. She could feel his erection pulsing against her belly and she moved against him, caressing him with her body.
He pulled her hands above her head and held her firmly against the door as he focused his attention on her neck, kissing, biting, and teasing the skin with his tongue. Her breathing got faster and faster as she got more and more aroused and she struggled gently against his grip, wanting to touch him everywhere.
At last he could stand it no more and he pulled away and towards the couch in the reception area. She took charge of the situation, pushing him into a sitting position and straddling him.
