It was about an hour's drive from our house to Atlanta. Mom and dad were invited to spend the night at her friend’s big mansion after the party. I f...lt like I was expected to be a chaperone from my younger siblings, which in the case of my out of control brother was quite a chore.I followed my parents to the party and valets took our cars to park them. Mom was re-adjusting everyone’s outfit, ties, and so forth, so we wouldn’t embarrass her. We walked up to the entrance to this huge house and. And both my sister and my aunty were shocked. They covered there breast and pussy with the clothes that were lying down and with a fear they called me inside. Then my aunt hesitantly asked me “ what have you seen my son” and I replied “ the whole film aunty” both were looking each other with fear. Then my aunt told me the reason for doing this all. She said after my uncle death she was not satisfied with her sex life. There was no one to have sex with her. She was dying for the sex and he could. Except for an occasional contented sigh, one would have thought Mom were dead.I moved from between her legs and lay down beside her. I idly caressed Mom's tummy, moving my hands in circles and occasionally cupping one of her breasts.After several minutes had passed without either of us saying a word, I felt Mom begin to stir. She slowly rolled onto her side and looked me in the eye. "You are a very talented young man," she said in a reverent whisper as she reached for my penis. She gave it. All over my body. Mmm, yes, just let me get off. I love your dick in my asshole.”I let out a frustrated snarl. I pulled at the branches binding my wrist. I let my weight drag at the tree. It rustled. The branches bent, but I couldn't rip my hands free. I wanted to seize her hips, hold her in place, and sodomize her so hard. I wanted to make her pay for her teasing.Maybe I would. My orgasm swelled so fast. I fought making any sounds to announce it. Kimmie was so into fucking my ass right now..
