Several years have passed since I had started fucking my young twin teenage niece's, Beccy and Pippa. Now the girls are in their late 20's, but both still as sexy as hell. Pippa always the more adventureous lives with her current girlfriend, a cute 21 year old student - but that doesn't stop her fucking a man when she feels like it. And often she feels like her Uncle Mark.

Beccy on the other hand is married, with triplets! Very pretty young girls, and unlike Beccy and her twin sister, these three are identical. Gemma, Hannah, Olivia. Three 11year old versions of Beccy, heavenly. But Beccy still loves her Uncle Mark, especially when he comes round during the day and fucks her on her own marriage bed, or on one of her daughter's beds.

And me, well I'm still single, and fucking both my nieces when I can.

Chapter 1

"Enjoy ?" Beccy asked, staring pointedly at my cock.

I climbed next to her on the bed and lay back gazing at my niece's still tight sexy young body, and wearing just thigh boots and stockings. She climbed on top of me, and I felt the cold leather against my bare thighs. Then she raised her body over mine and lowered her pussy lips to inches above my erect cock. She paused a long while, gazing into my eyes and then she took an inch into her and then stopped. I could feel the tightness of her pussy around the head of my cock. It was hot, wet, and tight. After a few seconds, she moved down even more, engulfing almost half of my cock. "Ummm!," was the only sound she made. All this time she continued to stare into my eyes. After a few more seconds pause, Beccy sat down fully on my cock.

As she ground down on me Beccy sighed and whispered, "Oh, God!" She then leaned over, brushing her breasts lightly against my chest. Her mouth pressed against mine and she tongued my mouth. She broke the kiss, and whispered, "Uncle Mark, it's all the way in. I can feel you filling me up. I can feel every little ridge on your cock and feel it throbbing. Oh, Uncle Mark, it just feels sooo gooo-ood." ......(cont)
