I was staying with my best friend for a few days. I should point out that I'm nearly 30 and my friend is 19 (I used to work with her and we kept in touch). She is absolutely gorgeous with straight brown hair, fantastic small breasts and the most perfect body you've ever seen.
One day she called me into her room to look at something. When I arrived, she was sitting at her computer and asked me to come over and proof-read her CV (resume) for her. Since she only has one chair in her room she gestured for me to sit on her lap which I did then she put her arm around my waist.
After a couple of minutes of reading her CV, I realised her hand was slowly moving downwards towards my crotch and I was instantly rock-hard. Her fingers brushed against the tip of my penis through my jeans then she jerked her hand back to my waist.
Her hand stayed there until I pointed out a spelling mistake. She leaned closer to the screen to take a look and, as she did, her hand slipped downwards again. I corrected the typo and went back to reading and as I did, her hand closed around my shaft and she said 'Wow' quietly. I turned to look at her and asked what she'd said. 'Nothing' she replied so I went back to checking.
As I read further she started slowly rubbing my cock through my jeans. It was getting harder to concentrate on the document with her fingers caressing my manhood and before long I leaned back into her and felt her firm breasts press against my back. 'Finished?' she asked me.
I told her I was having trouble concentrating and she said she could help me with that. She unzipped me, slipped her hand into my jeans and pulled out my penis. Her hand was surprisingly warm but her technique was incredible. She was timing her strokes with my breathing and with each upward stroke she rubbed her fingers agross the head. When I thought I couldn't take anymore she started pumping really fast and she whispered in my ear that she wanted me to cum right now.
It was too much to take and with a grunt I shot my load right into her hands. While she licked my semen off her fingers she asked if I felt better. Oh yes! She lightly kissed me then pushed me off her lap and grabbed a tissue to clean up.
It's the only time anything like this has ever happened with her but I'm wishing it will happen again.
