Sarah walked down the road towards her tutor's house. A range of emotions ran through her; the shame of being bent across the desk and spanked like some little school girl... and fear, of the burning pain she'd felt across her backside as her tutors' hand had spanked her remorselessly for what seemed ages. But she couldn't deny the twinge of excitement she'd felt as she'd bent across the desk, the cool air on the damp gusset of her pants as she stretched for the other side of the desk and waited for the spanking to begin. Just thinking about it was making her crotch moist again, and as she reached the gate to his house, she paused.

Fear and excitement mingling together, she walked up to the door and rang the bell.

"You're late."

"I'm not late," she said - panicking immediately. "It's five to seven, which makes me early!?"

"It would do if you were supposed to be here for seven, but you should have been here half an hour ago. Don't you remember?" He was standing on the step, staring down at me and clearly annoyed. "I would have thought after your last lesson, you'd have at least managed to be on time. You do realise what this means?"

Not even through the door and already Sarah could see where the evening was headed - but while her stomach clenched, she couldn't help but wonder how it would feel, bent over that desk and waiting for the first strike...

"Get inside; we've some catching up to do in more than just your maths ability and the sooner we start the better."

He moved back in the doorway to let her pass, but left little room so that she was forced to brush past his chest as she turned sideways to get through. As her breast brushed past him, she could feel the nipples hardening and her body reacting - his strong body and handsome face turning her on in ways she'd never known before.

"I can see that I was far too easy on you last time. So we shall start with a test; twenty questions, that you should have no problem getting right. For every question wrong, you'll receive three smacks on your behind. You have twenty minutes; our time starts NOW."

Sarah rushed to sit at the desk and grabbed a pen from her bag - shaking with the adrenaline pumping through her body, fearful of the sting and pain of his striking her backside (not to mention the shame of it) but also struggling to concentrate on anything other than his body and the bulge in the front of his trousers.

She started through the questions. The first few were OK, but she quickly realised as they got harder she was starting to lose concentration - the further it got, the more she realised she was making mistakes... but also, the wetter she was becoming between her legs.

"Time!" He called, as Sarah finished the last question, almost breathless by now. "Stand over there and wait while I check your answers". She moved to the side as he sat at the desk and started to mark the paper - and immediately it was obvious it was a long way from a perfect twenty.

"Only nine out of twenty? Is that the best you can do? What have you been doing for the past two nights if not practicing what we went through last time?"

He turned in the chair to face her. "You know what's coming. Come here, and drop your skirt."

She stepped in front of him and undid the hem of the skirt, dropping it to the floor. She was now standing just feet in front of him - his face level with the ( very wet) crotch of her pants. He sat for a moment, looking straight at her crotch - and the excitement she felt building inside was sending her crazy--

"Since clearly last time was insufficient persuasion, this time it will be on the bare." And with that, he reached forward and grasped the waistband of the cotton white panties.

On the bare? Holy shit - this can't be happening - but clearly, it was! Slowly he moved the waistband downwards, peeling them down her thighs and revealing the triangle of light pussy hair, now fully in view. As he pulled them further even she could smell her arousal, and he paused as the gusset of the panties stuck lightly to the moist lips of her crotch.

"What's this? It appears that this 'punishment' is hardly having the desired effect?"

He moved forward, sniffing the air mere inches from the parting between her legs, as her heart rate went through the roof.

"Are you actually ENJOYING this?" He spoke sternly, but quietly - looking up questioningly for an answer.

"I don't know! I'm confused! Yes! No! I, I, - it hurts, so no - but...." Sarah was panicking - the closeness of his face to her now completely bare crotch was turning her on like nothing she'd ever know, yet at the same time she felt so ashamed of the way her body was reacting

He reached forward, and gently ran his finger across the gusset of her pants, the back of his knuckle just brushing the hairs between her legs - her knees felt as if they were about to give way as she struggled to stand. Still, he sat in silence, as he rubbed his finger and thumb together.

"We shall come back to this, once we've completed what we set out to do," he said quietly. "Bend over the desk - you know the position?"

She moved across to the desk, draping her body over as she reached for the rail below. She hooked both feet around the legs of the desk and felt herself opening, cold air on her wet inner lips and blood pumping around her body.

He gently caressed her buttock and then she felt the hand withdrawn... SMACK. Fire erupted in her behind as he began. SMACK, SMACK as his hand rained down pain - and yet as the burning in her buttocks rose, so did the heat in her crotch and she found herself grinding against the edge of the desk, looking for relief. Again and again, his hand smacked down against her bare bum, and then suddenly it stopped, and she draped down against the desk, her inner self longing for the release that her body now so needed.

At that moment she felt him close behind, and his hand began to caress her burning backside, stroking back and forth... and then a finger traced its way down from the small of her back. She held her breath as the tip of his finger rested gently on her bum hole, and found herself raising her buttocks towards the finger, willing him to do more. She gyrated gently against the desk, now completely lost in the moment as his finger moved slowly to the wetness between her legs, stroking back and forth - barely inserted, but just the fingertip, now soaking wet, sliding against her aching clitoris.

"Please, Please....don't stop. Please I NEED this... anything, please - just don't stop!" she cried.

He slowly increased the pace and she felt herself building towards the now inevitable orgasm - which, when it came racked her body as she clung to the sides of the desk.

As the rush subsided she realised he'd move away and was observing her from afar, her half-naked and exhausted body resting across the desk, her bare cheeks both glowing from the spanking and the smell of sex pungent in the room.

"So. It seems we may have to take a different tack if we're to succeed in getting you through your exam. As you know, I've never failed with a student - but possibly you didn't know that my methods will often vary from one student to the next."

"Next time, it won't just be a hand spanking - it will be substantially more severe - but the reward at the end may also be greater if you come fully prepared - and on time - for your next lesson. In future, you will receive your pleasure if you PASS the papers, rather than if you fail."

"Stand up, and get dressed."

"Do you think that is likely to give you sufficient encouragement to actually study for these tests?"

Sarah slowly stood, picking up her pants and pulling them gently back up her legs before retrieving her skirt

"Yes, sir," she said. "I think that will help a lot," was all she could manage.
