“You’re not wearing any knickers,” I said, in surprise, but it was hard to keep the smile off my face. “What’s the point?” Casey replied, ...ith a girlish smile, “They wouldn’t be on very long.” I turned Casey’s nightdress back, and gently but thoroughly explored her sweet young pussy with my tongue and lips, taking her to the brink of orgasm, but not letting her go over the edge. Then, when I knew she was ready to come, I fucked her gently in the missionary position, as we kissed deeply, and she. I could feel the wetness leaking out of me. I wondered if the wetness was visible to Gary as he glanced at my crotch, looked away, and then glanced again. God this was such a rush. My face burned with a combination of excitement and embarrassment; embarrassment about what I was doing; and embarrassment at how exciting it felt to do it.I thought I could see his penis arch up and grow each time he glanced between my legs. I liked knowing that my private parts excited him as much as his erection. "Fine, come over tomorrow and I'll show you," I instructed.When she arrived the next day, I told her, "If I tell you this, you have to promise never to tell anyone else. This is very private for both me and Girl." I promise," she said eagerly.We were in my room, but she was still surprised when I said, "Strip!" However, she complied."Lie down," I told her, and she did. She started complaining when I began to tie her down. "You wanted to know about us, and this is part of it." You like to tie. I dropped my hand and stuck it in Sam’s knickers. They were tight and Priya could see the outline of my fingers in Sam’s pussy. Sam was wet and I began to use my fingers along the length of her slit. I felt her breathing deepen and she pushed her bum back against me.“James, bend Sam over that table and fuck her from behind.” Priya’s words once again were almost a command.Sam and I were insatiable and moved quickly to follow Priya’s instructions. We were both putting on a show and enjoying.
