Here's part four of the story - and probably the final part unless I get some good suggestions of where to take the story from here. Thanks for all your feedback so far - and look forward to any more.

I stuck my tongue out at him and tried to wipe some more of the cum off my face before sitting back on his desk. His eyes ran over me taking in the sticky trails of cum across my tits.
"Lay back" he ordered, and as I did, he stepped between my thighs and fingered the waistband of my knickers.
I looked down at his determined face as with a quick pull he ripped my knickers off me leaving me naked on his desk. The material pulling between my legs tickled and I giggled, moving my thighs apart.
His eyes were glued to my wet cunt, and he licked his lips as his head moved to my stomach. I gasped as he kissed it and my body tensed as he ran his tongue down to my pussy.
"MMMmmmmmm," I moaned out as he began to press his tongue against moist slit. I wriggled in pleasure as his warm mouth nuzzled at me.
He'd done this before I could tell – he instantly found my clit with his tongue and my body shook in pleasure.
"You're a juicy little slut aren't you," he said nastily, looking up from my pussy. I could feel a blush spread across my cheeks, but his words had made me even hotter and I couldn't help but slide a hand up to my chest, rubbing at my boobs. God I was such a slut.
He held my hips and spread my thighs further apart, licking noisily at my cunt. As the feelings increased inside of me my thighs gripped at his head and I began to groan out.
My other hand moved to my chest too, and I began to squeeze my boobs together and pull on my nipples. Oh god it felt good... I wanted to cum so badly.
But then he stopped and as I looked down to see why, he rolled me roughly over onto my stomach. The desk was cold against me and my hard nipples rubbed against the rough wood, scraping them deliciously.
I waited, panting in anticipation as he kicked my feet wide apart and spread my thighs wide. I looked back at him as he put his hand on my back and lined his dick up with my cunt.
"I'm going to fuck you like a dog Lauren. Doggy style like the slut you are."
