I left my sister at the park so I could get to work. It rolled around in my head how she had apologized for being a bitch to me all these years and belatedly I realized that she had actually been pleading with me and I had in effect pushed her aside because I was unsure how to react. Later I found that as soon as I left her she went immediately to my apartment to talk to the girls. She had already checked out of her hotel room and had planned on heading home after she visited with Tina and Tammy. I later found she changed her plans.
I arrived home from work that evening and found the girls dressed to play "the game" each was wearing the leather harness outfits and holding a riding crop. I loved how those outfits framed their tits and bare pussies. It gave me and instant hardon. The distraction of the outfits is probably why I did not immediately notice the woman who was on her knees between them. She had her head bowed till it was almost touching the floor. For a second I thought Stacey had dropped by but I realized that it was not Stacey's light brown hair I was seeing. He face was obscured and I did not recognize the rest of her. All I could see is that she was naked except for a wide leather belt around her waist and the handcuffs that chained her to it at either side.
Tina spoke. "Good evening Master. We have a new slave for you to train this evening. She has been bad and claims to deserve punishment. But we explained that only you can decide that. She is awaiting your judgment."
I decided to play along and find out who the girls had found for us. Never in my wildest dreams was I ready for what I found. I answered her. "Well what has the bitch done to be punished? Speak to me bitch."
At that command I heard her voice "I have treated my brother badly and abused his love. I am the lowest form of life and deserve to be beaten bloody." Then she raised her head and looked me in the eyes. I already knew from her voice but seeing the face was confirmation. Jen, my sister, kneeled before me naked and chained.
Now for the first time ever I called "STOP". I stood there looking at her and she looked at me and said. "Please not STOP. I need to do this. I need it." She pleaded.
"Do you realize what you are asking? Do you understand what punishment is and that it is real? Real pain! Have you ever played before, ever?"
"No I never have and yes Tina and Tammy explained in great detail what could happen and the rules. I understand about punishment and I also understand rewards. They explained that too. I am here tonight, to be trained and treated however you decide to treat me. To punish me like I deserve or to reward me. I am yours."
I turned to Tina. "Did you explain everything and were you explicit? You do know that if there was any misunderstanding I will be very upset!"
Tina answered without hesitation, "Yes Master. We explained it in detail and tried to talk her out of it but she pleaded with us. I told her in the end it would be up to you."
I looked at Tammy, "What have you to say?"
She looked me in the eye and answered. "Just what Tina said. It's what Jen wants."
I considered for a minute then kneeled in front of Jen and looked into her eyes. "You're my little sister I don't know if I can do this. I 'm supposed to protect you."
She very quietly pleaded. "Please try. I need this."
I stood and said "Ok we try."
All three of them smiled at me and Jen mouthed Thank you before she put her head back down to stare at the floor.
"Is dinner ready Tina." I asked
"Yes Master, would you like me to serve it."
"No. Have the new slave serve us. You can unchain her from the belt but keep the irons on her wrists. She can sit on the floor and eat until she earns her place. Tammy, bring my sweats and change my clothes."
Tammy scurried off to get my sweat pants and returned with them and a T shirt. As Tina exchanged the cuffs on Jen for the leg irons on her wrists to allow her more mobility to serve dinner, Tammy began undressing me. First she removed my shirt and helped me into the T shirt then she removed my slacks so that I was standing in my briefs with my bulging cock pushing against them. I looked at Jen and saw her lick her lips. "Odd," I thought "that she would react like that to me." As I stepped out of my slacks Tammy had kneeled in front of me to pick them up. She looked up at me and then at my bulging cock. "May I service you Master" she asked.
I hesitated. She was asking me if she could suck my cock in front of my sister. My sister had never seen me naked in my life. But then here she was kneeling naked on the floor in my apartment. I decided to push it a little. "Yes you may. But just a little I want to save it for later." I watched Jen's eyes as Tammy pulled the front of my briefs down and my cock sprang free. Then as Tammy drew me into her mouth and started to suck me while bobbing up and down." Jen's eyes got big when my cock came into sight and a slight gasp escaped from her. She stared intently as Tammy gave me a blow job and after a minute or so began to squirm around a little as though she were getting horny at watching her brother get his cock sucked.
Like most teen aged guys I had had fantasies about my sister. Hell she was cute and after she started to develop I got a couple of peeks at her but I always slapped myself down. I was supposed to protect her from perverts not be one of them. My parents had trained me well from the time she was born I had been told I was her protector, that I should look after her and I did, as best I could. Now here she was, watching me get a blow job and apparently getting horny over it. Could it be possible that she had had fantasies about her big brother?
I let Tammy work on me for a bit before telling her that it was enough and she had done well. She beamed with pride at the compliment. Just then Tina took Jen to the kitchen so she could serve dinner. We sat at the table and she brought us our dinner and drinks and served us as a slave would. Then she sat on the floor next to my chair and ate off a plate she held with her manacled hands. She actually did very well. I was waiting for some minor infraction so I could threaten punishment and test her resolve to "play". Finally she screwed up. While clearing the dishes she knocked a pot off of the counter onto the floor.
"What was that bitch?" I called from the dining room.
"Nothing." She called back.
"It did not sound like nothing. What happened?" I demanded
