A jog in the park (true)

I took up running in the summer so 3 days a week off i went anyway one day i was joined by a good friend of mine it was a hot summers day when we set we had been going for about 25 mins when she got cramp she lay on the ground and held her leg up for me to stretch when she had her leg up i could see right up her shorts and she had no panties on this got me instantly horny i had perfect view of her pink pussy wich i must add looked very moist i could also smell it i'll never forget that scent, after stretching her leg i think she noticed my bulge she leaned over and grabed it taking my cock in her hand she asked if this is what i wanted#/ i just nodded and let her continue she wasnt stroking she was more just squeezing i leaned over to feel her pussy but she wouldnt let me this teasing was gettin me real horny she then lay me back pulled her shorts to the side and sat on my cock i've gotta say i didn't last very long she was so tight and wet after about 2 mins i was pumpin her full of my hot cream after that we got up and finished our jog and haven't since mentioned it?? we've been on a number of runs since and this has never happened again! should i ask her for some more??? or was i not good enough because i didn't last very long??? comments please..............
