Sir was stroking his cock not six inches away from my face. I wanted him to command me to lean forward and lavish it with my mouth. I wanted him to reach out his hands, grab me by the hair, and fuck my face. I wanted him to jerk himself off and spurt his come on my face. I wanted it so badly, I could barely remember ever wanting anything else.
But I couldn't have it, not unless I'd earned it. And I couldn't earn it now unless Sir had already decided that I'd earned it earlier, before dinner, before I took my place at his feet. I was completely at his mercy: I knelt beneath his desk on the sybian, buzzing at a teasingly low speed, my legs taped to either side of it, my arms strapped tightly to my torso. There was a spider gag in my mouth, as there has been for the two hours I'd been here, wanting nothing more than to be of use.
Sir suddenly kicked the sybian into medium gear. "Come," he ordered lazily. I complied, juices running down my thighs, which had gone numb from the vibrations and lack of movement almost an hour ago. It was nothing compared to my relief. That was my eighth: if I had only managed to earn ten, then I had been good enough to earn his cock.
But it soon became clear that I had not been good enough. The sound of the key turning in the lock reached my ears, and I whimpered in terror. Madam was home, and I haven't earned the privilege of being touched in over a week.
"Has she been good?" she asked, after kissing him deeply.
"Not good enough," Sir replied sadly, still stroking his cock. "She only earned eight."
I cringed in shame. Madam sighed, disappointed.
"I think she might need to spend the night in the shed," she told him. I whimpered again: I knew it was coming, but I still hated the shed.
"We can't go easy on her just this once?" Sir asked hopefully.
Madam laughed. "You just enjoy watching her eat your come out of my cunt," she teased him.
"Do I ever!" he said. They kissed again then, and kissing lead to stroking, and stroking lead to Madam sinking down on Sir's cock, still inches away from my face.
When they stood, there was fluid dripping down Madam's legs. I longed to clean them with my tongue, longed even more for Sir to force my head down against her pussy as he pounded into my ass. I wanted her fingernails to claw into my breasts and his hand to beat my backside purple. I wanted to be touched, I wanted something human on my skin, whether it bought pain or pleasure.
Madam and Sir left me beneath the desk, the sybian still on medium, as they showered and readied themselves for bed. It was second nature by now, not to come, to hold myself on the edge of climax, but that didn't make it easy.
