My mother started to pinch her hard nipples between her finger and thumb. She moaned louder as she did.I pulled my cock from my pants as I watched. I ...was pulling on my cock watching her. Her one hand drifted down between her thighs. She rubbed at her pussy as her other hand caressed her tit.I did not know at the time this was how a girl jacked off. I watched pulling my dick wildly. My mother placed her ass against the glass door. It showed perfectly as she rubbed wildly at her pussy.“Ahhh fuck. But other than the pictures, it had all been give and take. Could I really just send someone a story about what I did in my room, alone, to make my body feel so good that I couldn’t hold back an orgasm anymore? “What are you wearing?” he asked, pulling me back to the present moment. I confessed that I was wearing my pink lacy panties and a football jersey. “Take them off,” he told me. After a moment of indecision I could feel my arms rising to pull my shirt up and over my head, letting it. There was none of the “what have you been doing lately” nonsense. For one reason, I knew that Mom and Kris talked on the phone every day, and I would have lunch frequently with Dad. They knew what we had been doing lately at least as well as we did ourselves. It was Friday night, and after cocktails and hors d’oeuvres, Mom served a beautiful dinner. It was French haute cuisine, and was superb. She hastened to inform us that the dinner was due to Kris’s coaching.Finally we were just sitting. His cum starts to leak out of my vagina. "I better go clean this out." "Okay. I need to get going anyways mom." I notice it's only 7:30 a.m. "Where are you going this early?" "I have a special class today." "Oh well okay. Will you be home when I get off of work?" "Yeah I should be." "Okay well I'm looking forward to it." I give him one more kiss and then wink flirtatiously. "Me too. I love you mom." "I love you too son." Five hours later and I'm halfway though my shift at work. My boss has told.
