All warnings apply. This concerns a parental spanking of a teenage girl. It is somewhat twisted and not to be taken seriously. It's fiction, folks!

One week before her fifteenth birthday, Lisa found herself in a situation she had promised never to be in again. She was certainly going to get spanked! It was a small mercy that she was caught in her newly acquired smoking habit while she was young and could still quit, and that she would be punished before her birthday. Her dad believed in a rigid system of punishment. She could always expect one whack of the strap for every year of her age.

She sighed as she slipped off her sandals and peeled down her shorts. She faced the bed with hesitation, but she knew exactly what to do. She lay across the bed face down over the pile of pillows and opened her long legs until they reached opposite sides of the bed. She then locked her knees on the sides of the bed, thrusting out her bottom. Her dad reached into the waistband of her cotton panties and lowered them down her thighs until they were stretched as far as they could without breaking. The force of the fabric of the stretched panties pulled her knees tightly against the edges of the bed, which she now straddled.

In other contexts the position might seem erotic or even obscene. Her soft, pink young labia was thrust out several inches above her lowered panties. Her crinkled brown anus seemed to glare rudely at him. The globes of her bare behind were separated as if they were independent of each other. He had to endure this unwholesome sight. After all, the most sensitive flesh was only available in the more spread out positions. Any strapping that was not as painful as could possibly be would be a disservice to Lisa. It would be sending a mixed message.

The first thwack exploded on the young teen's behind bringing water to her eyes. She screamed loudly, surprised by the searing pain that seemed to consume her. Her dad aimed the strokes at her lower bottom with enthusiastic force, allowing for short pauses to allow the extraordinary pain to sink in. By the third whack Lisa was sobbing uncontrollably. Animated by the shear pain of a strap-fired bare behind, her body clenched the bed and pillows desperately. As the strapping progressed, her sobs became louder and more anguished. Her ankles clutched the edge of the bed as her bare toes curled as tightly as a fist. Her long legs stretched and splayed with a life of their own, revealing and then almost, but never quite, concealing her most private parts.

The strap whizzed through the air a thirteenth time and landed on the nubile buttocks with dizzying force. Her dad paused for a moment, and watched his daughter's kicking feet and convulsing young body. He listened with satisfaction to her screams and sobs, the result of a punishment well deserved. He had never punished her before so close to her birthday, and it was so important--no--essential, that she receive the number equivalent to her age! He lifted the strap again and brought it down across the fullest curve of the teen's behind, criss-crossing red blisters that had already formed and eliciting the most piteous of wails from Lisa.

At this point he realized that it was as good a time as any, with her behind thrust up over the pillow, with her panties stretched to the breaking point by legs spread wide apart, to reveal to her what he and her mom had been meaning to say for so long. As soon as Lisa's wails quieted somewhat, he said "listen sugar, you were adopted. You were at least two weeks old when they found you abandoned near the dumpster at the salt mine, on the day we celebrate as your birthday. You are certainly fifteen years old!"

Lisa's breath disappeared, as she almost forgot the pain of the previous fourteen whacks. The strap whizzed through the air a fifteenth time. At contact, she cried and screamed like she had never in her life. Her dad wondered why the final whack seemed to be so much more potent than the previous put together. For now, he was satisfied. He had accomplished two duties of adopted fatherhood at once. He looked forward to all the conversation he would have with Lisa after this revelation.
