I caught my Aunt with her hand in her panty and rubbing her pussy. She tried to cover it. She loved me from my childhood and admired me with my youthfulness. I dared to sit beside her and engaged her in sex chatting. I placed her hand on my pajama under which my cock lay. She blushed and i let her open it. Out popped a full erect handsome cock. She held it in hand. I whispered to her that we will keep our affair strictly secret and become best friends if you tell me how is my Mom doing? She told me that your Mom is still young at 50 and we use a dildo in sex. I fucked Aunt twice until she was most satisfied and swallowed my cum. She took some in a cup for my Mom. Next day I called a farm hand from our Farm house and by showing him a couple of sex movies made him horny and took him to the Aunt to share sex with him in a threesome joined by my Mom. She told me "your Mom and me have made him our boy friend."
