Not the first time I've had to stop to relieve myself, I tend to find a quite lay-by at least once a week, have a walk in the woods and have a gently rub of myself most often bringing myself off if there's no one about, we'll today was a bit different. I was in a different area and found a small lay by right next to a wooded area with a little ditch running through the middle, very quiet and secluded!! So I decided to take a stroll rubbing myself trough my trousers as I walked, getting harder by the moment, I checked there was nobody around before undoing my zip to release the pressure, I reached in and managed to manoeuvre my now erect cock out of my trousers. I walked a little further and was struggling with wanking and walking so leant up against a tree and undid my trousers fully as I leant back eyes closed I could feel a cool breeze across the wetness of the end of my cock I pulled my foreskin all the way back and as I pulled it back and forward a couple of times the back of my hand got drops of precum on it so I pulled my foreskin right back and rubbed it into myself, fuck this was good. I took another cautionary look around before pulling my trousers down enough that I could rub my balls too, all clear so I proceeded to wank myself off, slowly to start, pulling my foreskin all the way back and forward then holding my foreskin back with one hand and rubbing the precum up and down my length. I must have had my eyes closed for a couple of minutes and was going full stroke, I could feel myself starting to cum and just as I started I opened my eyes to make sure I didn't come all down myself, I let out a huge sigh and my first spurt shot out at such a force that it went a good few feet in front of me and it just kept coming and coming, it was then that I noticed that on the other side of the ditch about 20 feet away from me was a middle aged standing there starring at me, I hadn't a clue how long she'd been there, she didn't say anything she just started at me, and there's me with my trousers down erect cock in my hand foreskin pulled back and cum still dripping from cock. I was a little embarrassed to say the least especially as my hard on wouldn't go down, I decided to just walk away with my trousers half hitched up and my cock still out and as I turned to walk away she just smiled at me. Writing this with a hard on now just thinking about it again, hopefully I get back down south soon
