Spanking My 'Secretary'

"Sex?" was the single world text I received from Becky one Saturday evening. "Yes. Dress up?" I replied. "Ok" she texted back. We'd already discussed what we wanted to do the next time we had sex, so little else needed to be said. I changed out of my casual jeans and t-shirt into my business attire and sat in my home office to wait for Becky. After about half-an-hour she let herself in and joined me. "You wanted to see me, Sir?" I turned and looked her up-and-down. She'd dressed in a knee length skirt and blouse buttoned modestly all the way up, her glasses completing her secretarial look. My eyes lingered on her bust, the red satin of her sexiest bra just visible though her close-fitting blouse. Her nipples were erect, dimpling the fabric. (She later said she'd played with her nipples in the car on the way over, knowling how much I enjoyed the effect). My member stirred and began to swell. "I've received emails from the IT department about inappropriate usage of your computer." "The porn? I didn't think anyone would mind." "Your colleagues have also reported some unprofessional behaviour." "You're not going to listen to gossip, are you Sir?" "They say you touch yourself at your desk," I said, standing up to move closer to Becky. I reached up and placed a hand on her breast. "Like this," I demonstrated, caressing and gently squeezing, the erect nipple pressing against my palm. My other hand lifted the hem of her skirt and slipped between her legs, fingers lightly stroking her sex through her panties. She gasped. "It's true, I do masturbate at work," she said between moans as I continued to touch her. "What's the problem of a bit of pleasure?" "Your attitude is very unprofessional, Miss Jones. Am I going to have to discipline you?" "Sorry, Sir. You're right, I have been naughty and I should be punished. I deserve to be spanked." I pushed Becky towards my desk and bent her over it. I lifted her skirt and pulled down her panties, the red satin fabric falling around her ankles. I raised a hand and brought it down firmly on her bare bottom. Smack! She gasped and I raised my hand again. Smack! She cried out and moved her hand between her legs. My erection was straining uncomfortable against my trousers so I unzipped and freed my stiff, throbbing cock, the head already wet with precum. I stroked and spanked while she fingered and rubbed, moaning, panting, whimpering. "More," she begged breathlessly. "Harder please, Sir." A few more firm spanks were all that were needed to tip her over the edge into orgasm. Her body heaving and trembing as she came with a wordless cry. I stopped spanking and focused on my own pleasure, masturbating vigorously, eager to cum on her. I climaxed, grunting and shuddering, spurting all over the smooth reddened skin of her lovely arse.
