Su enorme culo me la tapaba completamente y casi no podía respirar. “Lame la raja del culo”, se la lamí de arriba abajo, estaba sudada y no sab�...a muy bien. Al rato de estar lamiendo, me ordenó, “Ahora, métela por el agujero del culo “.Localicé el ano con la punta e intenté metérsela. Le metí la punta y pensé que no cabía más. Una palmada en los huevos, me convenció que siguiera intentándolo. “Mete más, cerda, que cabe más y cuando esté dentro, remuévela hasta que te lo diga”. Tenía razón,. She wasn’t letting go. “Show me how much cock you really want, like a true naughty little bitch.” Her eyes lit up with the challenge and she set off immediately. Her mouth clamped around my shaft and her tongue darted out. Her whole body began to rock and thrust backwards and forwards, swinging on her cuffs. The door shook with every thrust as she squeezed every inch inside herself, trailing her tongue down my length and licking her way back up, lips still sealed around me. My head fell back. Then she slowly got down on her knees. Her body was flexible and agile. Squeezing down between the seats wasn't a problem for her.And there it was. My sister was on her knees. Naked. Looking me straight in the eyes.She held my hard cock with both hands. It was then that I finally appreciated how soft and delicate her fingers were. They felt heavenly.But that was only the beginning. She bent forward and took the head of my cock in her mouth. With her lips wrapped around me, she used her tongue. I was starting to feel really tired but a shower did wonders for me. I looked at the clock to work out the time in Vancouver where my mother now lived. It was just after three in the afternoon here in London, which would make it about seven in the morning there. I was just about to ring her with the news when the phone rang. Clare was on the line."Hello Tom, I've just seen the doctor and I can come out." Brilliant! So everything's ok then?" Well, not quite. Laura's got a slight problem. She has.
