What had started out as illicit meetings strictly in her chambers behind locked doors only at night had expanded and branched out and they had begun s...eaking off to her rooms in the mornings or throughout the day, essentially whenever their schedules would allow them to.She was making up excuses more and more often as to why she needed to spend time with the boy, but they were worried that others, those who wouldn't understand, were getting suspicious of the pair, namely one of the other. I and my twin brother had been sleeping in their bed room till we entered our teens and they never wait us to sleep before they started moaning and squealing in pleasure. When I started understanding this world a little bit, I had already seen them many times; stark naked and making passionate love in their bed room, thinking we were fast asleep. Seeing my mommy and daddy naked, my pussy would often start kindling and getting wet and I had even seen my twin brother, always putting his hand in. My gran opened the door to me and invited me in, “what do we owe the pleasure of” she said smiling, “I thought that I would come around and see you, I have not been here for some time and I thought you might want to see me” “ho, come here” she took me in her arms and kissed me on the check, I was tingling all over, “let’s take a look at you” she looked at me and then I noticed that mole I had seen just in the picture, the one just on the side of her neck, it was her and my heart raced, “I am. She was wearing a black bra and matching panties.God, she looked so fucking hot I wanted to bang her hard more than anything.She took the initiative and made me lay on the bed, took my boxers down and began to suck me. She was a pro at it. She knew what she was doing. Top to the bottom till my balls she was sucking me in the best way possible.I was completely ecstatic. This went on for some time. Then I stopped her just before I could’ve cummed. Then I released her rebellious, delicious boobs.
