This went on for many years. I would watch mom suck dick, fuck guys one, two, three, sometimes four at a time. Sometimes with other women. Always a cr...ampie as it seemed mom did not like rubbers at all. Of course as we k**s hit puberty and watching mom have sex just made us more horny and we soon started to explore our bodies and that of each other also. My brother being the oldest and my sister being in the middle were first to fool around then when it was my turn sister knew more of what to. Holy shit what a great feeling. My senses were in overload. After a while Tanya went back up and started sucking Amy’s clit. My dick slipped out of Amy’s pussy and into Tanya’s mouth. Tanya sucked me with great suction which was almost too much for me. But Amy grabbed Tanya’s hair and said, “My clit you sissy.” Tanya switched his/her sucking back to Amy’s clit and Amy started to convulse into her second orgasm. When she had calmed down, she again switched around so she was facing me and started. I ran run hands up and down the beautiful stockings and they felt divine against my skin, my cock was straining hard against the flimsy fabric of the panties. I ran my hands up over my chest and pinched my nipples through the bra thinking about how Paula's pert titties and puffy pink nipples must nestle delightfully in it when she is wearing it. I started to stroke my cock now and went over to the bed to lie down. I noticed a strand of long dark hair on one of the pillows and reckoned this was. I did a good job catching it. I had to because I hadn't brought anything to clean my mess up.I stood there for a moment, just staring at her and wishing I could have shot it all over her face and those lovely mounds. My cock was down to about half mast, and I turned and made my way quietly out the door. When I realized what I had done, I suddenly became extremely nervous. What if I'd been caught? But at the time I made the decision to do it, all I could think about was jerking my cock to.
