Jack cleared a space on the desk in the center of the office before bending me over it. Shivering, I braced myself on my hands at the far edge of the desk, bent nearly at a ninety degree angle. His hands, hot against my skin, trailed from my shoulders down my spine. He traced the straps still holding that damned butterfly vibrator in place, and I flushed.
"I've given a lot of thought to how I'd like to punish you," he told me, fingertips trailing along my thigh. "A filthy slut like you is going to need lots of punishment."
His hands came around from behind me to cup my breasts in his hands. My nipples were tender from his pinching and pulling, but they were hard against his hands. He teased them gently with his fingertips. I groaned, arching into his hands.
He came to stand in front of me, rummaging around in one of the desk drawers. He found what he was looking for and showed it to me with a flourish: two small black metal binder clips.
I had a bad idea about where this was going.
Sure enough, he pinched one of my already-sore nipples until it was hard enough for his satisfaction. That accomplished, he quickly clamped one of the binder clips over it, pinching and squeezing the delicate flesh. I cried out sharply, twisting in attempt to get away from the sudden sting of pain.
Jack laughed.
He repeated the process with my other nipple, ignoring my whining protests. When both nipples were clamped to suit him, he stepped back, just staring at my breasts, swinging heavily beneath my bent body, tipped with my tortured nipples.
He flicked one of the clips, and I groaned, shuddering, unable to twist away from the pain.
He crossed back behind me, and I tensed, unsure what to expect next.
What I didn't expect was for the vibrator to start again.
My body jerked at the unexpected stimulation, which caused my breasts to swing again, which further emphasized the pressure at the tips of my over-sensitized nipples. I whimpered, trying to still my body.
Jack's hand fell sharply on my ass, causing my body to rock forward again, breasts bouncing. "Fucking slut," he taunted. I whined as he continued to spank me, hard, his open hand on my ass. I wanted to lean down, rest my trembling body against the desk, but the clips on my nipples kept me from doing so. I was torn between leaning down to rest my body, to keep my breasts from jerking and bouncing and further abusing my clamped nipples, and avoiding the added pain of the clips pressing into my breasts if I put any weight on them.
The slaps to my ass came fast and hard, eventually bleeding into a steady stinging pain. The butterfly hummed merrily against my pussy, ramping up my arousal, blending the pleasure with the pain and humiliation.
All the while, obscene, filthy things spewed from Jack's mouth. He punctuated each slap with another nasty insult or comment: "Fucking bitch," he snarled. "Dirty little fuckslut. Look at you, your cunt is dripping all over. Nasty whore, you love this, don't you? Such a fucking cocktease, and look at you."
I couldn't do anything but take it, my arms shaking, my thighs trembling, my pussy aching at the unceasing teasing from the vibrator, my ass burning, my nipples still screaming at their abuse.
My head fell forward, resting my forehead against the desk. Each strike at my ass sent a shudder through my body; my breasts jerked and bounced, hitting me in the face, and I didn't have the will to move. The vibrations against my pussy ramped up, and I whimpered, my hips pumping against nothing.
Jack noticed the frantic jerking of my hips, and the vibrations stopped suddenly. He landed the hardest blow yet across my raw ass. "Dirty whore," he proclaimed.
