Every saturday night me and my mate would go out and get drunk (usual nights for 19 year olds), On our way home we decided that i was gonna crash at his house and stay in his sisters bed cause she was away for the weekend. So i did, he told me before that he was told he had to work early on sunday so he told me to just leave when i get up (i have known him and his famly all my lives so i was no stranged thier).
The morning came and as always after i have had a drink i wake up with a serious hard-on and well i knew it was going to happen but just getting up and putting on my jeans and leaving who would notice. I got up, still half asleep and rubbing my eyes i looked across and saw my mates sister standing there with a cup of tea waiting for me.
"Hiya Lee" she looked at me with a smile. I took the tea and took a few sips and then stood up but it was only until i looked down at my boxer shorts that the button was undone and my cock (still rock hard) was poking right out. I was embarrased but the look in her face was nothing to worry about, she looked right at it "wow" she remarked. For some reason i left it sticking out and she was still looking at it, it was almost like i wanted her to touch it or something. All of a sudden she whispered into my ear "my brothers at work and my mums gone shopping" and i already knew his older sister is away until tuesday so i turned to her and kissed her on the lips.
She laid down but i knew she had never done this before perhaps never even seen a cock before cause she still hadnt taken her eyes off. I took off her pyjama top and saw her perky breasts sticking right out as i started nibbling on her nipple whilst slinding my hand down her bottoms feeling her tight pussy. With cock already sticking out of my boxers i could feel her hand softly touching it but shaking. I stood up and and pulled my boxers right down "there is condoms in my drawer in my room" she told me so i asked her "why have you got some" she answered "my mates made me buy them for fun, good thinking now hey" she stood up and went into her room whilst she was gone i asked myself why am i doing this, am i taking advantage, she is only 15 but then a concoince hit me and replied she is 18 next week (which she was) so i thought here is my birthday present
She returned and offered to put it on me i replied "no" she had to suck it first so i laid down and she went to get on top but i told her "no, i want you suck me first" she looked at me and said "are you sure" i replied "don't worry i show you what to do" She put her lips around me cock and put it in her mouth but with no experience she didnt even move her hed she was just moving her tounge round so i grabbed her head and started moving it up and down.
