My parents divorced when I was six years old, and my mother remarried when I was fourteen years old. My stepfather Stephan was a colleague of my mother, and he had a daughter from his previous marriage, with the name Camilla. Unlike my mother, Stephan was a widower instead of a divorcée, since Camilla's mother had died in a car accident a few years earlier. After the wedding my mother and I left our rental apartment and moved into Stephan's house.
Though Camilla's was about seven months my junior, my stepsister tried to dominate me from the first moment. To be honest, I was quite attracted to Camilla, as she was a beautiful girls. So my stepsister succeeded quite well in dominating me. Whatever she asked me to do, I did so without complaint. But because of this, we developed a strong and intimate bond with each other. My stepsister was smart enough not too much from me, that it would negatively affect my performance at school.
At my fifteenth birthday Camilla woke me up:
"Congratulations my dear bother!"
"Thank you very much, Camla."
"Sammy, I have a special gift for you."
"What kind of gift?"
"I will give you a birthday spanking."
"A what?"
"I will put you over my knees, and then I will give as many smacks as your age in years plus one to grow up."
I had never been spanked before, neither as punishment nor as birthday present. Of course, I knew nevertheless that a spanking meant to be painful, at least to make sense as a punishment. But I was quite curious to find out how it would feel to get a spanking, so I complied with my stepsister's desire.
Without hesitations I stood up, and my stepsister was sitting at the edge of my bed. Camilla had already been dresses, while I was still in payjamas. Subsequently I bent myself over her lap, and when I lied with my belly on Camilla, she grasped me in a strong hold. Then she smacked my butts with her flat hand, it did really hurt. But simultaneously the spanking excited me.
Camilla administered the smack right after each other, hence the whole spanking was over within a minute. After the spanking my stepsister asked me:
"Did you like to be spanked, my bother?"
"Yes, I did."
"Maybe I should spank you once a week?"
"I think you should spank me more than once a week."
Camilla smiled, and said:
"Let's start with once a week. We can see later, if you need more frequent spankings."
Thereafter my stepsister pulled me up, and we started kissing and hugging.
