"Come in Saunders what have you been doing to find you requiring punishment again?"
"Smoking Sir but it was the others who were smoking I was just found with the cigarettes in my bag."
"Well just possession is enough to earn you this punishment. I see it is you third this term, which means I have to be far harder on you this time. Now I am required to have a female member of staff with you so I will ask Miss Bennett to come and join us."
"Please Mr. Stern don't ask her to come in. It is embarrassing enough but I feel very uncomfortable around Miss Bennett, can you not just punish me by yourself?"
"I see you were eighteen last week in the circumstances I will respect your choice if you are sure that is what you want. If I do I will expect you to do what I say immediately."
"Thank you Sir."
"Okay, take your shoes off you can leave your socks on. Given this is your third punishment please strip to the waist and put your blouse and bra on the chair along with your skirt."
"But Sir..........?"
"Do it now unless you want Miss Bennett here too. My goodness you have developed hugely this term."
"I think my boobs have got much bigger since my Mum put me on the pill. It is rather nice as it has certainly got me noticed by the boys."
"I am going to start with the strap as it is a little less damaging than the cane, which we will finish off with. I should add additional strokes to your punishment as your knickers are not standard issue. I will leave that to be decided later. Now, reach across the table and grip the far side with your hands shoulder width apart. Your feet should be the same distance apart."
He stepped back knowing that she would not be able to see him as he drunk in the sight of her full bottom made even better by the lacy knickers that would offer much less protection than standard school issue. He reflected that it was not full it was large but firm and toned by training. He indulged himself by slipping his fingers around the legs of the knickers as if to straighten them. She was not taken in but did not protest.
He applied the strap to the middle of the bottom without great force. He knew that he could strike her much harder than this without doing serious damage. Each of the next five was applied with increasing force spread around the substantial target area. The intake of air and moans increased in volume after each blow. He was delighted to hear the reaction and would never consider asking her to quieten down. Putting the strap down on the desk her told her that the next six would be applied to her naked bottom. As he moved behind her he exclaimed.
"My goodness have you had an embarrassing accident here Saunders?"
"Oh Sir, sorry Sir no I have just got rather.... well a little..... eh kind of excited Sir. I didn't mean to I can't help it. It just happened Sir."
As he peeled her knickers down he realized that indeed the wetness that showed as a wet patch on her knickers was sexual arousal and not pee. This was further confirmed as he pulled them down past her knees and the aroma of sexual excitement flooded his nostrils.
"My goodness have you had this type of reaction previously? It is an extraordinary reaction to being punished."
"I don't think I have ever had a reaction as strong as this but I have got a little excited before. I am so sorry Sir it is so embarrassing. Can I go and sort myself out before we carry on?"
'That will not be necessary Saunders. I am sure as the severity of the punishment increases your body will react differently. The next six with the strap will be much firmer."
With this he took up position to recommence the strapping. She was not the only one in the room to be aroused by events. He had to rearrange his erection as it was not only very visible but it was very uncomfortable. He always enjoyed spanking, strapping or caning an errand bottom and this was a beautiful one. He took his time delivering the next six again increasing the force until the last couple were as hard as he was comfortable administering. It was a good thing that the sound proofing of the room was good as she was now screaming after every strike.
He was enthusiastic to see what effect the second half dozen had had on her. Far from drying up, juices were running down both of her legs and her pussy was clearly swollen and red. He wanted to enjoy embarrassing her as much as possible. He ran his hand up both her legs getting close but stopping short of her pussy.
"I love to cane a wet bottom and there is plenty here to soak the whole area. Let's just mop you up a bit I think I will use your knickers."
Having had a good feel of her bottom as he used his wet fingers to trace the stripes, he took her knickers and finished drying the inside of her legs. He then wiped from the wet center of her pussy up until his fingers covered by her knickers found her large hard clit. The wail that left her lips was very similar to her reaction to the strap but they both knew it was from pure arousal. He circled her clit time and time again enjoying her excited discomfort.
