Suddenly, I heard little grunts and her shadowed leg and body jerked. I backed out as quickly as I could. This was heavy stuff. I had jerked off bunch...s of times, even a few in the shower, but I had NEVER thought about my sister doing that, too. It was likely that moment was what changed my perspective of her. We were both horny teens!DOING ITOne evening, our parents were out at a dinner party while we both sat on our family room couch eating pizza and watching TV. She had graduated from high. We children and swetha’s dad were in Sumo and all my parents are in another car. I sat beside her at back seat. It was 10pm and were in middle of the journey. I pretended to be asleep and tried to fell on her when ever the driver applies the brakes. She asked me to sleep on her lap so that it would be comfortable to sleep. I immediately slept on her. Now when ever a brake I moved my hand closed to her pussy while pressing her thighs smoothly. She bent and saw me close whether I am in sleep or. Oahaohhh ..aaahhhhhhh…..”.Then I felt all things under control.So I took her to bedroom and she lied on the bed. Again I kissed her on her lips and I started to lick her lips even faster to make her more aroused. This time I was upon her and my cock was pressing her wet panty. I moved my hands to her butts and caressed them tightly making her struck to me closely. Her breasts were touching my chest giving me very much pleasure. I made my hands move on her butts in a circular fashion. She hugged. I slid my hands down my legs on top of the smooth stretchy fabric. As my hand trailed down to my inner thigh I felt the dampness between my legs. I so much wanted to touch myself right then and there. The pangs of tension were rupturing through me. I needed to be satisfied and I needed intense pleasuring.I pulled my blanket over me. I bent my knees and held them up with my feet grounded at the end of the seat. I then slid my hand under my knee and slowly twitched my middle index finger and ran.
