Christmas eve, Mon told me we were having an extra guest for Christmas day. An old friend who was on his own this year. My step dad seemed cool about this, and we all had a nice Christmas day. As the grown-ups had had plenty to drink, our guest syaed the night in my bro's room (we was staying with is Dad a few miles away) Boxing morning, I got out of bed and went into the bathroom... Our guest was already there, about to turn the shower on, and completely naked! I muttered sorry and backed out, but not without noticing he had a fairly big dick! I listened as he splashed in the shower, then a few minutes silence before he came out, a towel wrapped around him. He glanced at me through my bedroom doorway and smiled "good morning" I smiled back, and think I went red as I noticed the bulge under his towel. He paused while he tried to think of something to say... "have you got anything exciting planned for today?" was the best he could come up with. No, not really. There was a pregnant pause. He was looking at me, in my oversize T-shirt and nothing else. "what would you like to do today?" he said coming towards me, and standing close over me. I was stuck for an answer, and the scent of his after shave was overpowering. Then suddenly he moved closer to me, putting his arm round my shoulders. "you're very beautiful, you know..." Ok, so I have alim figure and long black hair, but my tits are teeny, and I always thought men went for big tits. This one didn't! He turned my face to him and kissed me firmly yet gently on the kips. I melted back onto the pillow, and before I knew what was happening, I felt his hand under my t-shirt on my crotch. As he laid down beside me, his towel unravelled and his cock reappeared, bigger now than it had been before. Instinct took over and I reached out to touch it. It was firm and hot and strong. I guided it to my pussy, and felt the warmth as he slid slowly inside me... The first part of this story is true... I'm waiting for the morning, hoping the rest will come true too!
