I didn't have anymore arguments as she sucked my cock hard and fast and had me cuming in her mouth in seconds. She swallowed the lot then started to take of her top, I never realized how fit my sisters body was until she slipper of her jeans and was just standing there in her white thong that was going slightly see-through at the front. She pushed me back on to the bed and sat with one leg ever side of my head her pussy just inches from my face, I couldn't take it any longer and pulled her thong off to reveal her beautiful shaved pussy, I slipped my tongue in to her pussy and found her clit and began to gently lick, nibble and tease her. she was cupping her own tits and rocking back and forth on to my face.
I carried on doing this for several minutes until she told me to stop she wanted my cock in her pussy, "take me now little bro" I began to gently ease in to her as she lay on the bed. Not knowing how much she could take, but I soon realized she wanted it as hard as I could give it. I was soon pounding in to her as hard as I could, never having fucked anybody like this before it didn't take me long to shoot my load into her beautiful pussy. This time she cum with me screaming the house down as I emptied my sacks in to her. I thought she might want to rest after that but far from it, it was clear she wanted more and she started to stimulate her pussy her self.
She asked if I wanted to cum on her tits and my grunt was all the answer she needed. Once again it didn't take me long the thought of doing my sister just had me cumming in no time. She licked in up of her chest as she continued to finger fuck her own cunt giving me a bit of a show. We have been carrying on like this for two weeks now, I hop my mum and dad don't come back to soon.
