She agreed after I confirmed that all my home work was already complete.When I got back, grandma was already in her room preparing her bed. Jeeth chet...an gave a naughty smile seeing me back. He and latched the doors after I got in asked me to go to the north side bedroom, while he makes sure that grandma is sleeping. It was the room that was farthest from where grandad and grandma were. I waited in the north bedroom; it was a big room, previously used by one of dad’s sisters. I could see Jeeth. I followed her. She was making the bed as I came in. She looked up and smiled. She turned from the bed to face me when I walked to her. I put my hands on her blouse over her breasts.She put her hands over mine.

As she was trying to figure out what to say, she felt his hand come down on her face. Not hard enough to hurt, but hard enough to get her to answer correctly."I'm sorry Sir." That's better bitch." "Now get your clothes off whore."Tammy did.
