Tracey's story continues from chapter 4. Brandi has agreed to being trained to be ready for her daughter. Her daughter, Erin is due to arrive home in the afternoon.
A short recap from Chapter 4:
Justine had a wicked smile on her face and said, "You want to be our sex dolls, don't you Brandi? You want to be our fuck toys, our pets."
"Yes." Brandi replied breathlessly.
"You're going to leave a message for Erin and tell her to come over here when she gets home. I'm going to tie you up and let Erin watch while I fuck you with a strap-on. But first I'm going to train you in how to enjoy pain. You're going to submit to me, be my slave, aren't you Brandi?"
"Yes." Brandi replied again.
"Then tonight I'll make your daughter my slave as well, the two of you will love becoming my slaves, won't you?"
"Yes." Brandi replied again to Justine.
Then Justine smiled at me with that evil smile of hers and said, "Now sister slave. We ae going to commence Brandi's training."
I looked back at my sister, smiled and said, "Yes mistress."
"And remember Tracey. Brandi's daughter wants to seduce you. That's the key to having both mother and daughter join us."
I was very much looking forward to tonight. Having my sister control and direct not only me but a mother and daughter was making me feel so hot.
Friday Afternoon
We were in Justine's room. Brandi had red leather cuffs round her wrists and ankles and a red leather collar on. She was also blindfolded with a red silk mask. Her wrist cuffs were attached to a rope that led up to a ceiling ring. Her ankle cuffs were attached to a spreader bar. This had the effect of making her stretch up to the ceiling and making her push her beautiful huge breasts forward, while her legs were spread apart showing off her beautifully rounded and muscular ass. I was kneeling in front of Brandi, watching my sister flog her back. Each time the flogger struck Brandi's back she shuddered in pleasure and pain. This had been going on all afternoon, Justine had been experimenting on Brandi to confirm what her pain threshold was. She constantly spoke to Brandi while she did this, telling Brandi that Erin and her were going to worship their mistress as mother and daughter. That Erin and Brandi were going to become mother and daughter fuck dolls and perform for their mistress. That mother and daughter would learn to worship each other's bodies night and day for the pleasure of their mistress.
"Fifty, thankyou mistress" Brandi said.
"Very good slave," Justine said and then looked at me smiling. "Now mommy slave, your daughter is going to lick your pussy again until you beg her to allow you to orgasm."
I had been playing the role of Erin, Brandi's daughter, all afternoon. I hadn't spoken and with Brandi blindfolded the repetitive pain and then pleasure had re-enforced in Brandi the fact that it was her daughter's tongue bringing her to orgasm each time.
"Thank you, mistress. Please lick me Erin, mommy loves your tongue on her pussy."
Justine stepped around behind me and leant into Brandi. I looked up while I continued to lick Brandi's pussy and watched as my sister applied nipple clamps to each of Brandis breasts. The clamps were connected via a silver chain. Justine pulled on the chain stretching Brandis nipples out. Brandi moaned in absolute pleasure and said;
"Oh, thank you mistress for the pain, thankyou daughter for the pleasure, thankyou mistress, please pull harder, I want to be your pain slut. I love how you dominate me while my daughter licks my pussy. Oh Erin, can mommy cum, please let mommy cum Erin."
I'd pulled her hood back and was massaging Brandi's clit with my tongue. It was driving her wild, I loved the feeling of a lover doing this to me as well, so bringing Brandi to orgasmic bliss this way was deeply satisfying for me.
"Please, oh please Erin let mommy cum. Mommy loves your tongue on her clit, but I need to cum."
Justine pulled on the nipple clamps again, elongating Brandi's nipples. God it looked hot watching her nipples stretch out as Justine pulled harder on the chain.
"Oh, thank you mistress for the pain, please, please Erin let mommy cum. I'll do anything for you."
"Anything?" Justine asked Brandi. I suspected Justine had been waiting for this breakthrough.
"Yes mistress. I'll do anything for my daughter if she just lets me cum."
"Your daughter did tell me what she wanted Brandi. Would you like to know what it is?"
"Yes mistress. Please tell me, I'll do anything Erin wants."
"Well Brandi, your daughter told me she wants mommy to fuck her with a strap-on while mistress and her sister watch. Will you do that for your daughter Brandi."
"Oh yes mistress, I will."
"Tell me," Justine said. Her words had power, authority.
"Mistress I'll fuck my daughter with a strap-on while your sister and you watch. I'll fuck her in any position she wants, for as long as she wants. Oh, please Erin, may mommy cum now?"
"Your daughter says mommy slut may cum now. Cum for your daughter mommy slut."
Oh my god, I could taste Brandis orgasm in my mouth straight away, she was cumming over and over in wave after wave of orgasms. As this happened my sister gave a strong tug on the chain connected to the nipple clamps on Brandi's breasts. Brandi's nipples stretched out and then snapped back as the clamps pulled off each nipple. Brandi screamed in pleasure and began squirting all over my face. I was awash in her cum, it covered my face and breasts and was dripping down my body. I ran my hands all over myself covering my body in the slick cum that Brandi had released on me. God, I felt my own orgasm release as I did this and I dropped back onto the floor, exhausted.
Both Brandi and I had passed out from our orgasms, when I opened my eyes again Justine was removing Brandi's blindfold and kissing her on the neck and cheeks. Brandi's eyes fluttered open and she had a smile and look of utter contentment on her face.
"Thank you, mistress," Brandi said. "I want to do everything for you."
We untied Brandi and let her down. We all went into the shower and began washing each other off. Justine's shower was a mirror of my own, big enough for at least four people with a nozzle on each wall. The warm water felt wonderful as it washed over my body.
When we got out of the shower Brandi and I sat naked together and did our make-up. We then brushed our hair into matching high ponytails. Justine told Brandi to wear a red latex dress and I was to wear a matching black latex one. We were both naked underneath them. Justine also told us to wear our dress collars, Brandi's red to match her dress and mine black. Then we put on wrist and ankle cuffs, again matching red and black. To finish it off we wore red stilettos for Brandi and black for me. I was amazed that Justine not only had different dress sizes but also different shoe sizes.
At the same time Justine had dressed in her black leather full body harness. Over the top she wore a sheer see through white shirt, tucked into a short black skirt, thigh high stockings and black stilettos.
Justine's hair was done in an updo and she finished the look with a pair of thick rimmed black glasses. She looked, very much like the strict teacher.
Friday Afternoon
We all walked downstairs, and I poured everyone a glass of wine.
Brandi had sent Erin a message to meet at our place and Erin had replied back to say she would see us at around six, thirty minutes away. We were standing around the kitchen bench, Brandi and I both nervous about the night ahead, whereas Justine appeared cool and in control.
I looked at Brandi and said, "So tell me what you and Erin talked about when you went home last night."
