The door closes as he turns from the window, precum sticking to the lace panties he was left in. "She's going to come back, right?" he asks himself quietly, looking at the empty spot on the floor where his clothes last lay.
A few minutes tick by—tortured by the thought of having to make it to the garage wearing only the thong of his lover, and more so by the thought of disappointing her by not following her commands—he makes his way to the office door. Poking his head out, he sees a janitorial cart at the far end of the hallway. With any luck, he'd be able to slip into the stairwell unnoticed. No way was he going to be a sitting duck in an elevator for any custodian to spot.
Flying down the stairs as quickly as he can, he stops at the landing to the lobby. He hears the hum of a vacuum cleaner behind the receptionist desk, and his cock stiffens at the idea of being trapped in this dingy stairwell, having to wait for the other person to leave. He hears Her words ringing between his ears, "Oh, and Lovey? Don't even think about touching yourself," but his hand is already wrapped around the lacy fabric, tightening around his cock. Surely just a little teasing wouldn't get him into too much trouble, he thought.
The vacuum humming drowned out the sounds of his labored breathing, his throbbing cock twitching in his hand as he slowly stroked it with the fabric of the panties. His mind wandered to Her, and what she had in store for him had his cock begging for release. He hadn't heard the vacuum stop, he was so entranced by his fantasies. Finally, after a moment or two of mind wandering, his cock exploded, covering his belly and panties, and falling to the floor of the stairwell.
Panicked at the thought of being found, pathetic in panties and covered in his own cum, he made a run for it. His shaky feet found their way through the lobby, to the garage and to his car before he was able to take another breath. In the car, he looked for something to clean himself off with, finding just a single napkin - not nearly enough to hide the evidence of his rule breaking. He sighed and started driving to Her, knowing he was going to pay for this.

She's preparing the room when he arrives. Slowly and shyly, he kneels at the door, waiting for her acknowledgement.
"You took your time, pet."
He blushed, knowing his indiscretion will not be going unnoticed tonight.
She walks towards him, her long hair brushing across her back with each step. She looks at him, noticing the wet stain on the panties she made him wear. She reaches down, slipping her hand down the front of the lacy material and grabbing his balls forcefully.
"Stand up," she commands, using his balls in her hand to guide him to his feet. Her grip softened, but he knew not to trust it. She doesn't like rule breaking, and she sure knows how to punish for it. This wouldn't be the last time tonight his balls ached.
Her fingers slipped through his hair, bringing his face closer to hers. She looks at him, taking in the patheticness of it all, then kisses his soft lips.
"I see someone didn't follow the rules," she sighs into his neck, one hand still in his hair, one still softly gripping his balls. "Lovey, I know I put you in a tough situation tonight, taking your clothes and leaving you stranded in such a cute little outfit, and I know how hot that must've made you, seeing as you've ruined my panties. I am just so happy you're finally home."
