The three matrons marched her in to the punishment room while Sara kicked her legs and cursed. Fortunately the three were a match for the 18 year old schoolgirl, but it was very obvious that she would need to be strapped down for her discipline.

The three matrons hoisted her over the sturdy leather sofa, and while two of them held Sara in position, the third drew her arms down full stretch and strapped her wrists firmlyto the base of the heavy sofa legs.. A stout belt was pinned around her waist over the sofa, and a third strap secured around her knees, and Sara was firmly secured. I found it very pleasing to have this sturdy ruffian, dressed in her white blouse and short wool skirt, the image of so many of my night time fantasies, now actually strapped down in front of me. "In the mood for the cane Sara?" "No?" "Lets see how you feel about it after we remove that little skirt you are wearing!"

My hands trembled slightly as I found the small side clasp and drew the skirt down her trim teenage legs. Now I had this squirming tomboy in her underpants. The elastic tightness of her white schoolgirl knickers straining with the plump fullness of Sara's rear cheeks, broadened and fattened by her bent posture.. She had struggled hard when being strapped down, and Sara's panties had ridden up the cheeks of her bottom, laying bare the fat lower curve of her bottom cheeks. I took the tail of Sara's white blouse and tucked it up under her waist strap. I hooked my thumbs in the waistband of her panties and slowly lowered the material, watching as her ass flesh rolled out from under the desending material. Sara's ass was now completely bare to my view.

I pulled my desk chair up behind Sara and sat down right behind her, inspecting this exciting rear view. Sara let out a gasp as she felt my hand fondle the slight heaviness of her rear cheeks.

"Presently I am going to use a bamboo cane across these pretty little bottom cheeks of yours Sara. I am going to enjoy it and I am sure I will have to unbutton myself and you will be able to feel the proof of my pleasure while I thrash you".
