When I was 14, my father re-married. Since my mom worked summers, while my Dad didn't (he was a teacher), I went to stay with him for the summer months. It was then I met my new stepmother and her 14-year-old daughter for the first time. They both seemed nice enough. On my third night, I was taking a bath when my new stepsister (Carol) walked in. When I told her to get out, she just laughed. I lost it, swearing at her at the top of my lungs. My stepmother came running in and asked what was the matter. When I told her, she glared at me and said she would not allow such language in her home, whatever the reason. I then got the surprise of my life. "Jason," she said, "I want you to get out of that tub this instant and dry yourself off." When I protested, she added loudly, "Now." With both of them still present, I climbed red-faced out of the tub and began drying myself. After a few seconds, my stepmother said, "that's good enough", and too the towel from me. She then grabbed me by the wrist -- I couldn't believe how strong she was -- and led me out of the bathroom into the living room, with Carol trailing in our wake, a big smile on her face. My stepmother sat down on a hassock and pulled me across her knees. For the first time I realized what she was planning -- she was going to give me a spanking!I couldn't believe it -- I'd never been spanked in my life! Before I could say a word, she brought her hand down across my bare bottom -- "OW", I yelled, as much in surprise as pain. This first smack was followed by a rapid succession of additional spanks, alternately from one buttock to the other. I began kicking my legs in an attempt to break free, but my stepmother had her left arm wrapped tightly around my waist and the kicking was to no avail. As her hand continued to smack my now very red bottom, tears welled in my eyes and I pleaded with her to stop. She paused, lifted me off her lap, and said, "I'm surprised that a big boy like you is behaving like such a baby. You know you've been naughty and have earned a sound spanking and that's what you're going to get, tears notwithstanding. Now place yourself across my knees again." Gingerly, I laid down on her knees. Not satisfied with my placement, she took me by the waist and pulled me forward so that once again my feet were off the floor. "Carol," she said, "fetch my hairbrush from my bedroom." Giggling, Carol left, quickly returning. As I lay naked across my new stepmother's lap, dreading what I knew was coming, I fought my tears, determined to show them both I was no baby. As the first crack of the hairbrush resounded off my bare butt I gritted my teeth, determined not to cry out. My stepmother methodically raised her arm and brought it down, expertly striking every part of my stinging bottom from the top of my crack to just above my thighs. But try as I might, I finally resumed crying. After what seemed an eternity, my stepmother put down the hairbrush and lifted me off her lap. As I stood before her, sobbing and rubbing my bottom, almost oblivious now to my nudity, I froze as she turned to Carol and said,"It's time you learned how to spank a naughty child -- soon you'll have children of your own. Sit down on the hassock." With that, I was placed across my stepsister's lap. As my stepmother gave her instructions on technique, Carol had one hand resting on my bare thighs and the other on my equally bare buttocks. With horror I felt an erection forming as I lay across my stepsister's lap. I knew she had to feel it, but she said nothing. The insructions concluded, my stepsister began slowly and methodically spanking me with her open hand. As I cried and squirmed, she paused as hermother had done to re-position me on her knees. But as she put her hands around my waist, I felt one hand slip around and brush against my erection. With asmile, Carol resumed the spanking. Finally, my stepmother directed her to stop and I was sent to my room. This was to be but the first of many spankings at the hands of my stepmother and stepsister, but the only one in which I would be completely bare. In the future I was allowed to keep some modicum of dignity, although my bottom was always bared.
