I wonder how much adrenaline I'll get today? I walk into the building, take the elevator upstairs, and strip down. Almost naked. I lift up my dress and pull down my panties. I hold the panties in my hands and wait with great excitement for the elevator doors to open. Will there be people there, will anyone see me. I step out into the hallway, there's no one there. I strip down to my bare feet, take off my shoes, get my beautiful new toy out of my backpack and put all my clothes in my backpack. I call the elevator to put my backpack in it. I'm really worried that someone won't accidentally arrive. Even though this isn't the first time I've experienced these emotions, I never have a plan for how to behave if someone sees me. I feel absolutely ridiculous and awkward about the whole thing, so whatever happens, happens. I stow my stuff in the elevator. And it rides away. I stay completely naked in the building and start masturbating. It feels really good and exciting. I jerk off in different positions, sitting, standing, jumping on the dildo, etc. I walk down the stairs completely naked and masturbate on the stairwells. The elevator rides up and down. I hope my stuff is back, because if someone steals it, how am I going to get out of here? I cum very sweetly, sitting on my ass, I enjoy my orgasm until the last second. I call the elevator, and wait for it....
