When I heard the knock on the door I still wasn't sure who I was going to find standing there when I opened it. Sally had finally mustered the courage to speak to me at work and, although more embarrassed than she had ever thought possible, she admitted that her knickers hadn't been dry since the day she had spent at my house. She wasn't sure she could convince her daughter to accompany her on her next visit but she confessed that she wanted to be used again.
Opening the door I smiled when I saw them both standing there. It wouldn't be true to say that they looked like sisters but it was plain to see that they were related. Nicola may have just turned twenty but she was already a mother and there were a lot of similarities between the two women. Not only were they of the same build, they both had similar hairstyles and both hung their heads in the same submissive manner. Given that I had had so much fun with her mother's body the week before, I couldn't wait to see Nicola undressed too. As it was pouring down both wore long raincoats and I wondered what delights were hidden beneath.
I ushered them through to the living room and sat down but did not invite them to do likewise. Leaving them standing before me like two naughty schoolgirls before their Headmaster, I looked them up and down, liking what little I could see.
"Well, Sally, what can I do for you today?"
She looked up at me in surprise as her daughter looked at her.
"Just what we discussed at work, sir."
If Nicola was surprised to hear mother address me as "sir," she didn't react.
"And what was that, Sally?"
She now realised that I was going to make her say the words in front of her daughter. Thinking about what I had planned for them both for the rest of the day, I thought that this was the easy part but I knew that for Sally it was deeply humiliating.
Her face burning red and avoiding her daughter's gaze, she looked me in the eye, took a deep breath and said,
"I want you to teach Nicola to enjoy sex the way you taught me."
Her head immediately dropped.
"You want me to treat her like a slut, to spank her, to cum on her face, to use every inch of her body for my pleasure, every hole?"
Sally could only nod while Nicola hung her head just as low as her mother's.
"And what about you, Nicola? Is that what you want? Are you ready for that?"
She didn't raise her head but followed her mother's lead and simply nodded.
"I wonder," I said. "Sally, show your daughter these photos, one by one, and let's make sure this is what Nicola wants to do."
I opened a large envelope sitting on the coffee table in front of me and withdrew a handful of very explicit photographs taken without her knowledge on Sally's last visit to my home.
She hadn't been expecting this and looked at me in question but knew better than to hesitate, taking them from my hand before blushing furiously when she saw the first one. Immediately clasping them to her chest she looked at me again.
"I don't understand, sir. How were these taken?"
"Oh, didn't I tell you? Every room in this house is fitted with miniature spy-cams for security purposes but obviously they have other uses too. Now show the photos to your daughter, my little slut."
The use of that word in her daughter's presence spurred Sally back into action and, with great reluctance, she handed over to Nicola the photo of her lying across my lap being spanked. The younger woman looked at it, incredulous, but that was just the beginning. In very quick succession, obviously hoping to get her shame over with as soon as possible, Sally presented her daughter with very lurid photos of her face covered in my cum, of her riding my cock and finally, of her lying down on my bed, her face buried in my pillows as I buried my cock in her arse.
Nicola kept looking at each photo in turn, not sure which one shocked her the most. Eventually, she looked up from them and tried to look me in the eye. Failing to hold my gaze, she lowered her head before giving me the smallest of nods.
"I asked you a question, Nicola. Do you want me to treat you the way I treated your mother last week?" I asked, my tone hardening.
Just like her mother she took a deep breath, tried to look me in the eye, and answered,
"Yes, sir. Please teach me to enjoy sex."
"Excellent, so now I have a slut and a whore to play with. Take off your coats and drop them to the floor."
Sally already knew the punishment for any delay in obeying an order and quickly unfastened her belt, opened her coat and dropped it where she stood. If Nicola had been shocked by her mother's appearance in the photos, she was no less stunned when she looked at her now. This week Sally had dressed as she had been told, black basque, black lacy thong, black stockings and black high heeled shoes.
