I’d teased him beyond control and it was just the beginning of his torment.As Dave ejaculated over the floor, his face reddened.Diane looked at him ...nd smiled. “Now you see why we need you!” She said cheekily.I took her hand and guided her to the bed. I spread her legs wide and knelt to taste her. She tasted amazing. I lost myself in her. Inhaling her scent and licking from the top of her clit right down to her puckered anus.She moaned and writhed and as I looked up I saw Dave had moved. When all the introductions were over the adults went into the sitting room to talk while Cathy and I went back upstairs for more "GIRL" lessons. After an hour of playing with makeup and hair there was a quiet knock on the door and we looked up to find everybody had come to my bedroom to see what we were up to. Leaving Cathy's parents alone with us "my" mom and dad went downstairs again. We quickly took advantage of being alone with mom and dad to explain, as best we could, all the things. “Okay if I sit here?” Alison asked. “Yeah sure sure fuck,” groaned the boy distractedly, while the girl, dick lodged between her lips, made a “mmff” sound as she nodded her head.A lot of the welcome pack consisted of glossy brochures, with lots of pictures of happy people fucking and getting fucked in all sorts of contexts: schools, hospitals, prisons, company board-rooms, aeroplanes, construction sites, etc. Alison found it a bit difficult to concentrate on reading the text, over the slurping. That is all we have. I’ll let you know when we have something else.”Pressing the end call button, I started making my way to Melissa. “You wanted to speak to me, Melissa!” I barked at her. That is when my mobile started ringing again. Rolling my eyes, I looked at the screen. The call was from Samantha.“Hi, Samantha, how are you? Are the kids ok?” I asked worriedly.“Hi, Jason we are all ok. We are down in London. The kids kept on asking about you. So, we got the national rail to come and visit.
