�There is more to it than that, if you do well on Rob he will send for you and it will be much better�. He will have you pleading for him to go in and you will enjoy it when he does�. In the drawing room, Sam told Alexis and Lena how the master had taken my virginity then told Lena she was wanted. �Come with me I will take you to your room, have an early night tomorrow we start you're training�. In the morning Alexis and Lena were there to help with my lessons as Sam took me to a well equipped gym saying this is where we exercise any time we wish, and over there you will see Rob. It looks just like a man in vest and shorts but he is a very special electronic Robot, which the master controls from that panel. He is like a man in every way and it feels like real flesh when you touch and sit on him. It is designed to teach a woman how to pleasure a man and responds to your stimulation it even ejaculates inside you if you fuck him, as you should.

He is set up now for you to practise on but it is possible for his member to be enlarged to any size the master wants. After you undress him, we will teach you how to get him erect then how to give a blowjob. You heard Alexis say she had to sit on the master, so your next lesson will be how to squat over him. If he isn't erect you must get him hard hold it and insert it into your fanny then sit down on it until it's deep inside then lift and lower until you feel him squirt his stuff. After dinner tonight you will show the master what you have learnt, and he will watch Alexis do her second sit for him only this time Rob will be that much larger.

Sam said women must be nude to give Rob the warmth of their body so I stripped and although the master had fucked me, I had never seen an erect penis and after they showed me how to get, a man hard with my hands I was surprised at how big it was. I was taught how to give him a blowjob and all the positions I was to adopt to give entry to my front and back. Being taught how to move up and down sitting on him with it in my cunt was all right but I didn't like it in my arse and was upset to think I might be used there. I didn't have any trouble doing the other things and all three thought I would perform well the next time the master entered me.

We all helped cook the dinner, Sam taking the masters to his private room. When everything was cleared away, I was all tensed up as I waited to give the Master my first demonstration. When the bell rang, Sam led the way to the gym; inside the master was sitting in a comfortable chair facing the robots head. Rob is ready for you women get yourselves ready for him. Alexis will go first for her second time Zo stand behind me and watch. Looking at Alexis I saw her taking her clothes off then she stood astride Rob and taking his shorts off started to handle his member like I had been taught earlier. I saw it grow until it was longer and thicker than the one I had this morning, I had found that hard to get in and wondered how on earth this would go inside a woman.

Alexis lowered herself and putting her hands between her legs parted her lips and lowering further the head disappeared. Her face grimaced as more went in then half way she stopped and started grunting. Not a lot more now the master said as she lowered further. Breathing deep moaning and biting her bottom lip it was gone and her pubes rested on the robot. Now work it the master said. I had been told how to do it and watching Alexis clenching her buttocks I knew she was making her vagina muscles grip and relax on that thing inside her.
