We all went to bed at round 10 and my sister told my aunt that I and she would sleep in the same room but without anybody else. since we were brother ...and sister my aunt dint even have a small doubt about what we were going to do and obliged first when my sister and I slept on the bed she said wait for a little while till everyone sleeps. But I couldn’t control. My cock was hard as iron rod.My sister knowing my feelings gently started to press my cock. aaaahhh it was an amazing feeling as it was. Her boobs were bigger than mine. We looked at each other and both liked what we saw. I started a conversation on lesbian topic I was surprised to know we both slipped into it smoothly and we jelled very well to fit like hand in glove. We also exchanged mobile numbers. She worked for a call center and I was at the hospitality industry, this was a reason I had never come across her at the hostel though we were both staying at the same place. I called her the next day expressed my desires and I. "Now be an even badder boy and shove that big cock of yours in my cunt."I had never heard a woman use the forbidden 'c' word before, but it sounded so hot coming from her.I stood up, aimed my cock at the hole and slid back into her warm cunt. I groaned as I started fucking her."Oh yes, sexy, pound my cunt with your big cock," she moaned, her French accent still sounding so sexy.And I did, wishing I could grab her hips and bury my whole cock in her; wishing I could feel my balls and body. I made a face of that I am thinking. Then told her that I have a thought in my mind. But you need to promise me that you won’t be angry.She said that we are friends and why I would get angry. I said fine and then gathering courage told her that the loser would give a kiss to the winner on the cheeks. She first showed some signs of anger and confusion. I said that you promised me that you won’t be angry.She said she didn’t expect this. I told that we are friends and a friend can kiss another.
