I have been waiting a long time for this.

Finally we are alone and know that no one else will disturb us. It is a huge turn on to realise that at last I can kiss you openly, wrap my legs round you, suck your cock, fuck you.

I take your face in my hands and kiss you, my tongue seeking out yours. You kiss me back – it seems to last forever, and I know that we are both desperate to fuck. I feel your cock hard against my leg and I rub against it. You bring me closer, your hands tight on my arse, pulling it towards you. My cunt is wet and I am overwhelmed by the desire to fuck you right now.

“I’ve been a very naughty girl, haven’t I?” I whisper.

“You have – a really naughty girl. So naughty that I can’t let you get away with it.”

“Are you going to punish me? I think you should.”

You turn me round, take my hand and lead me across the room. There’s a desk in front of us.

“Bend over and pull up your skirt. Put your arms on the desk and lean as close to it as you can.”

I do what you tell me. Your fingers trace the curve of my buttocks, then down my thighs to the tops of my stockings. Looping a finger inside my g-string you pull it down, then slide your finger into my arse and down to my cunt. I am soaking wet. I gasp and bend over further, opening my legs for your fingers. You slide them in and out, then stop.

Smack! Your hand comes down hard on my arse. The shock of it makes me gasp. Smack! Again – and again – and again. It is just hard enough to hurt, but also incredibly pleasurable, and I push my arse up to meet your hand.

After a while you stop. I am so turned on now, desperate to have you inside me, desperate to come. But first I kneel down in front of you. I unzip your trousers and take out your cock. It is smooth and hard. I stroke it for a moment, then take it in my mouth. I flick my tongue around it, then suck hard and rhythmically. You put your hands on my head and pull me gently towards you. I take your cock deeper into my mouth, and suddenly you cry out, then come - an explosion of warm, salty-sweetness in my mouth, my throat.

You take my hands, pulling me to my feet, then lead me to the bed.

“Lie down,” you whisper. “Open your legs.”

I let my knees fall apart, feel your tongue licking the inside of my thighs, working your way up to my cunt. Then your tongue is inside me, lapping my vagina, my clit, pushing deeper and deeper until I am squirming with pleasure.

“Fuck me,” I say. “I need you to fuck me now.”

You raise yourself up, push my arms above my head and pin them with your hands. Your cock slides into me – in and out, faster and harder and deeper until we can hold on no longer and both come. It is absolutely amazing.

Later we get up and go out to a bar. I wince slightly as I go to sit down.

“Are you all right?”

“Yes - my bottom’s just a bit sore from where you …”

You smile: “Well, we’ll have to do something about that then later, won’t we?”
