I found out their names … Mary, 13 years old, Jane and Alice were 12. They searched my cupboards and howled with laughter when they found my collect...on of women’s clothes, dildos, whips and porn mags. Mary made me dress up in suspender belt, stockings and padded bra. My face was red with shame and the girls laughed and insulted me as I dressed up. They took photos of me from all angles. Then Jane selected a short leather whip and I was made to lay face down on the bed. Mary held me down by the. I haven't yet, but it was always a temptation.Anyway, it was October, the Thursday before Kevin was up for the Challenge. I was watching Amy just before bedtime. She was on her mobile and holding a book. At the time, the most important thing was that she was in her bra and knickers and walking around talking, so I almost didn't notice the book. The book was a Mensa puzzle book.I figured it out straight away. This was the book that they used to set the challenges. From the cover, I could see it. I was gonna show him a good time. I could feel him pulse on my clit making my knees jump a little, pushing myself farther back onto him, his dick probing my pussy with a hot warmth. He tried to push closer but the wall prevented him from getting closer, I couldn’t help but tease him, brushing up against him, so close but out of reach. I couldn’t keep up my little game up much longer and gave into my senses, pushing myself back into him, allowing him to slide his cock deep inside, filling me. I let out a loud moan while grabbing the back of her head and pulling on her hair and pushing her head up and down on my cock, her full wet lips going up and down on my cock, she'd stop at the tip and swirl around my swollen head with her tongue, dragging her lips around it before going back down and sucking a licking again. I leaned over a little bit and pulled up her nightie and started rubbing and slapping her ass, my fingers made their way to her pussy and I was surprised to find her pussy.
