So Rachel wanted to begin the session right away. She taught us a technique we could use if a guy were coming at us with a knife. We were very impressed with her skills and were eager to learn more. She encouraged me to try it so I stood up and attempted to imitate exactly what she did. Joy was next and kind of fumbled it so she tried again with not much of an improvement. After a couple of more techniques, the instructor began getting hard. Much to our surprise Rachel knelt and started milking his cock right in front of us!! At first, we didn't know what to think, but she insisted it was apart of the program, so we sat and watched. I wanted to participate.  "Can we help?" I asked. They said sure, so I scrambled to my knees beside Rachel and began jerking off his cock. Joy was a little shy at first but she eventually came over and helped us work his stiff dick. All three of us were spitting on his groin,  lubricating his cock and balls.
