As we drank I said I needed the toilet and went for a pee to which she followed me to the bathroom and as I opened my fly and got my cock out she look...d and said 'that’s nice', (I must say that my sister and law has never married). And as I started to pee she put her hand over mine. Needless to say I started to get hard and as I finished she pulled me by my cock to the wash basin ran the tap and cleaned it with warm water and then knelt and licked the end. By now the pre cum was flowing and her. At the ensuing family function, my step mom apparently made my real mommy and my sister drinks to loosen them up. My step mother then proceeded to explain to my mom and sister, with help from my father, that she’d push to take away mommy’s visitation rights, unless she agreed to let herself get humiliated like the way they humiliated her a few weeks back.After much internal debate my mom agreed.My step mom was delighted.She instantly had me and my father remove our pants and pull up chairs. . Now I could see a huge woman lie naked in front of me, let me describe her body she had two monstrous boobs probably in the size of 44 .she was heavily built and her ass would be something like nothing less than 72 inches.For a while I was surprised and feared whether I can handle her but than my inner instinct said that this is what I was waiting for all these days i.e to fuck a elderly woman with a huge body. Slowly I started fondling her boobs and I could not catch her one boob in one hand I. Honestly its not what I had in mind. As I started counting up marks I noticed him put his hand under the table and checking out my young body. “So did I look good in your photo” He asked me. “What?” I said very nervously.He stood up with his hand still playing on his crotch. He looked straight at me and sternly said;“Get over here now boy!”I walked over keeping eye contact. I ran my hands up and down his chest then he grabbed my hands and told me to get down on my knees and suck his dick. .
