Gym buddy

Around 12 months ago I was looking to get back to the gym after a 12 month absence, i wanted to spend the first few months just working on fitness so the aim was not to touch any weights and just concentrate on cardio to start off with. I decided to hold off on the gym and build up my cardio outdoors with running and bike riding etc, after the first couple of weeks lack of motivation started to kick in so i started searching for a running buddy. I started my runs at 530am so no-one was keen until I eventually convinced an old friend from school. We decided we would run 3 times a week. She lives in the city so we decided it would be easiest to run around the lake seeing as she lived in the city and I worked there. I hadn't seen her for around 6 months so first morning we ended up walking the whole way and just chatting, barely even working up a sweat, I thought to myself at this rate I am never going to get fit! Day two came and we pushed it a lot harder, about half way through it started pouring rain and we looked like drowned rats by the time we got to her apartment. I usually go have some food and a coffee afterwards and then go shower at work but i was absolutely soaked so asked if i could just shower at her place and get changed there. We went up and I jumped straight in the shower, about 30 seconds later she came into the bathroom and started getting undressed and next thing i knew she was in the shower with me. She said she was frozen and had to wash her hair before work now that it was soaked. I was a bit in shock and didn't know what to say and just trying not to stare, she just looked at me and said were both adults, im sure you've seen a naked girl before and you're not the first naked guy ive seen, i just smiled awkwardly as she knew i had a girlfriend but it didn't seem to phase her at all. We continued to chat as i tried not to stare at her, i had no idea what her intentions were, i didnt know if she was just overly comfortable with me or if she wanted me to make a move. She was commenting on my body and said I had a nice cock in the same way you would say someone has a nice smile. When she bent over to pick up the shampoo bottle she made sure her ass was facing me and i could see the outline of her pussy, i thought to myself c'mon who does that unless they want some action! I could feel my cock growing but wasn't going to make a move. She got the body wash out and proceeded to wash her body starting at her tits and working down to her pussy, when she got to her pussy she seemed to spend what seemed like an eternity lathering it up, she then got her shaver and started shaving her pussy and moved onto her legs. She was acting like we were a couple who had been together for a few years as opposed to friends who haven't seen each other for a while. I didn't know what to do as i just stood there talking to her trying to act like this wasn't the weirdest morning ever while my cock kept growing. She lifted one leg up against the wall while she was shaving her leg and i had the best view of her pussy, my cock was now full size as she looked at it and smiled and said wow well good morning. She turned her shaver around and started rubbing the handle on her clit as she looked at me and said lets see if we can make him bigger, for the first time she had a serious look on her face as she started to push the handle into her pussy, sure enough my cock became even more erect. She moved close to me and said if you don't touch me in any way then technically you are not cheating, that theory made no sense to me but there was no way i was complaining watching a hot girl now finger fuck her pussy right in front of me. she gave me another cheeky smile as she dropped to her knees and started kissing and licking my cock, she put her lips to the tip and looked up at me and said 'i wont tell if you don't' I was so turned on a this point that all i was thinking is that i want to push my cock past her tonsils so i grabbed the back of her head and thrust forward into her mouth, she pulled out and said "nah uh remember if you dont touch me its not cheating" so i took my hands off her head as she started sucking my cock and licking my balls. she then got up and faced away from me and bent over slightly as she eased back onto my cock, i grabbed her hips and she slapped my hands away and said 'what did i say' i was in heaven but at the same time it was torture not being able to grab her hips and really pound her. I was fucking her so hard but apparently it wasn't cheating, hey i wasn't going to complain. She pulled out and turned the water off and grabbed me by my cock to lead me out. She sat me on the edge of the bed and continued sucking my cock before pushing me onto my back. She walked to the other side of the bed and knealt over my face, she then started lowering herself onto my face as i started licking her pussy, i could hear her moans get louder as she moved forward a bit so her ass was now in my face as i started rimming her, with this she leant forward and we were now in the 69er position. I was still licking her ass as she fingered her clit i felt her legs tighten as she started cumming and let out a long loud moan. She slid off my tongue and moved forwards so she was now in the reverse cow girl position as she lowered herself back on my cock. She worked my cock expertly as i watched her back arch forwards, i could feel myself getting close and told her so she hopped off and stood me up so i was standing over kneeling on the floor, she wanked and sucked me until i came in her mouth. we both layed on the bed and she laughed and said that she didn't believe that i actually held off not touching her. She said she always wanted to do that with a guy but never got the chance. She said when she got in the shower she didn't actually intend it on being sexual, i was so glad it did because it was such a great experience. She then apologised and said 'i know you have a girlfriend but i've been so horny the last couple of weeks' as bad as it was i definitely wasn't complaining. Seeing as we were in the shower for ages we had about 20 mins to get ready for work so she went to the bathroom to dry her hair as i got dressed. I got dressed and made myself a coffee and went back into the bathroom to get the rest of my stuff, when i went in she was wearing a bra and had just slid into her skirt as i caught a glimpse of the top of her lacy black knickers, i felt my cock instantly get hard. She leant over the basin to finish her make up and i couldn't help myself as i walked over to her, slid up her skirt, pulled my cock out and put it against her knickers, she pushed back and i knew she wanted it again as i slid her knickers to the side and pushed inside her, she had her hands up against the mirror as i finally got to grab her hips and fuck her hard, i undid her bra and cupped her tits as i was thrusting hard. She turned around and kissed me and grabbed my cock and pushed me back into the room and onto the bed. She picked up her phone while she stared sucking me and rang her boss to say she'd be late, the fact that she was licking and sucking my cock while talking to her boss turned me on even more. As soon as she hung up i picked her up so she was sitting on me with her legs wrapped around me and started fucking her hard. We spent the next hour going hard and eventually made it to work that morning. After that we never got back into running, i would go straight to her apartment in the morning for an hour session which was as good as running around the lake. We did try going for a run once and half way through it finished with her giving me a blow job in an alley way and back to her place to finish off. Amazing girl...
