You spanked it, now you're going to fuck it

"Have you ever been arse-fucked, Léa?" You don't see any point in pussyfooting about.

The blonde gasps and seems a little embarrassed, but doesn't blush visibly when she replies.

"Actually, Jaques, a few years ago, I was curious and my bloke and I, we tried, but he was too big and we stopped because it was not working the way we hoped it might. I have never in fact, uh, completed the act."

"Was he happy to stop?"

"Oh, yes, he was not so keen to start with. We were just experimenting."

"Well, for my tip I would like to complete that experiment."

Léa must have been at least half expecting this, but your words still apparently come as a shock. She becomes agitated, no longer the nonchalant woman of the world who stripped for and was spanked by a colleague without obvious discomfort.

"Yes, Jaques. I-I do not have any, um, lubrication. My bloke and I used a whole bottle when we tried, but it turned out it was not enough."

"Don't worry, we won't need any lube; you'll use your saliva instead. Kneel down," you order and she complies. "Now take down my slacks and underwear." She does, hands shaking a little. This is probably her first tip, you reflect.

"Now, take me in your mouth. You'll want to get me very wet, as I'm sure you realize."

The lectrice applies herself assiduously to your cock, clearly taking your advice to heart. Already nearly erect, you're soon fully to attention and Léa's hand hovers close to your shaft as though she's wondering whether to hold you while she sucks, but she seems to think better of it and instead tries to deep throat you without prompting. This makes her eyes water, which the bumps didn't manage, but after several attempts, she finally manages to engulf your entire length, slobbering over your member and stimulating you with her tongue.

"That's fine, Léa. Now go and bend over the desk." She avoided it during the spanking earlier, but now she will be making close acquaintance with that desk. You shuffle over behind her and she spreads her cheeks without being told.

You see that the light strapping had a bit more effect than you thought, because the inner curves of Léa's buttocks are a deeper red than the areas that were directly impacted. Nevertheless, it's the brown arsehole between that interests you at the moment and you prepare to **** your spit-slick prick inside.

Léa knows what to do, bearing down to ease your entry, but it's still a very tight fit and you can feel sobs reverberating through her body while you drive inexorably deeper. Soon, you arrive at your destination and reverse direction until you pop free, leaving a gaping purple passage. Léa sighs with relief, but it's short lived, because you order her to lubricate you some more. The act is obviously distressing, but the blonde doesn't hesitate, turning around and sucking you enthusiastically until you say it's enough and you're ready for round two.

This time, the entry is easier for you, although it seems even more painful for her, but after a couple more penetrations, you loosen her up enough to start thrusting deep into her bowels and satisfy your lust.

Her groans of anguish as you pound her virginal bum hole spur you to greater heights and rather than prolong the (admittedly delightful) experience, you aim to finish as quickly as possible. After all, she's a colleague and there's no reason to make her suffer more than strictly necessary to pleasure you satisfactorily.

You slam into her backside, your hips spanking her as powerfully as her belt, until with one final thrust, you spend yourself and come to a halt, throbbing in her rectum.

With a moan of contentment, you withdraw and although under normal circumstances, it ought to be the girl who thanks her spanker for allowing her to tip him, in this case, you feel it's appropriate to thank her for behaving professionally throughout.

"No, no, thank-you, Jaques. I was curious about the bumps and you have helped me and for that I am very grateful. Would you like to take a shower, before you go?"

You think about it, but decide to have her lick you clean instead; it'll be quicker and easier, as well as being good practice for when she inevitably has to tip a man for a punishment spanking at some time in the future.

"You know," you say as a pretty blonde laves your genitals with her tongue, "it's not just one birthday spanking you've missed, is it? You've missed all of them. At least since you turned eighteen. Maybe I ought to help you catch up with all of them. We could try a different style for each. What do you think?"

With her mouth full of cock, Léa takes a moment to respond, but when she does, she very considerately says she wouldn't want to impose further and one set of bumps is plenty to last her until her next anniversary. Still, you reassure her as you pull up your trousers and fasten the fly, it would be your pleasure to assist her, to which she replies that you're very kind.

You call a taxi and decide you will have that drink while you wait, so Léa dries her eyes and gets dressed in a casual white smock and you go down to the kitchen for coffee, chatting amiably about different types of birthday spanking the world over as if you hadn't just buggered her cruelly over her desk.

When the cab arrives, you say goodbye with a smile and promise to see each other again tomorrow, to discuss your plans for helping her develop her own spanking skills, if nothing else. Parting on good terms, you head home, more than content with the way your visit went.

The journey gives you time to think over the events of the afternoon and evening. It has certainly been an interesting and rewarding time and before you know it, your conveyance has reached its destination. You pay the driver and, taking your keys from your pocket, walk up the path to your house, glad to be home.

Opening the door, you're greeted by the glow of lights in the kitchen and are just wondering whether you forgot to turn them off when you left this morning, when a delightful figure steps from your kitchen into the hall in front of you.

Even by the standards of women attending the university, she is stunningly beautiful, peaches-and-cream complection framed by midnight-black ringlets piled high upon her head to expose an elegant neck rising out of a french-maid style outfit. She is tall and slender and could easily be a model or starlet, but you recognize her from the records you viewed earlier as Imogen, one of your grad-students, who's on the rota to do your housework and look after your domestic needs.

You are jerked out of your musings by a melodious voice saying "Welcome home, Professor. I hope you enjoyed your evening. I've cleaned the house and tidied the garden, so is there anything else I can do for you tonight?" She steps towards you, head coquettishly to one side as she adds impishly, "I mean, anything at all, Professor."

You feel your libido respond to this blatant offer and if you hadn't so recently sated yourself you might succumb to your desires, but as it is, you're spared the temptation of instigating sexual relations with a student outside the framework of a spanking tip.
