Next day we planned for a picnic to a famous fort in the district. It was a very tiring day as the fort was very big it took us 4 hrs to see full fort...our legs were paining very badly. As we got late there we missed the last bus for our home so had to take a lift in others sumo. We settled in back portion of sumo where seats are parallel, while sitting in sumo I used the trick as sat opposite to my mil, my wife sat next to me and opposite to my fil.I knew I have a chance and dint wanted to let. I grabbed the elastic band on the boxers with my teeth, and pulled them off. He stepped out and looked at me with excitement. I reached my arm out, grabbed his dick, and pulled him in closer. His cock was already dripping with pre-cum when I put my lips around it. He let out a slight moan as I danced my tongue around his sticky balls. I felt a rush of adrenaline as he clinched my shoulders. My tongue ran up and down the length of his growing cock, as the pre-cum dribbled off. I kissed the end. When I felt her clit begin to get dry I moved my fingers down a little further and dipped to them into her sweet cunt to wet them, then I moved back up to her clit and continued to rub and rub it until she began to really squirm in her seat. While I was rubbing her clit a hispanic man came over and sat down right next to my wife. After watching her writhing as I played with her clit for just a minute or two, the hispanic man reached down and unzipped his fly. He pulled out his dick which was. I went back to bed with a smile on my face and a boner in my pants."Down boy," I whispered to myself, "she's your sister."But the thought of her playing with herself had gotten to me. Soon after the noise stopped so I turned over and settled down again. I was just drifting off when I heard a door opening and light footsteps passing my door. Then my brother's door opened and closed."What the fuck," I whispered.Either Trish was in my brother's room after whacking herself off or, well she hadn't.
