This bizarre event happened a few weeks ago...Saturday morning, I had gone to bed far too early on Friday and woke up at about 3.45am, wife solid asleep and with a bad cold so no fun there, I tried to read some crap on my tablet, couldn't get into it so at about 5am decided to take our little dog for a walk, something I often do before daylight as it avoids fools with dogs they can't control, I put on a short sleeved shirt, football shorts and trainers without socks and took the dog out to the car... I decided to go near a disused airfield, about 10 mins from where we live, dog in the car and off we went, parked where I usually park and noticed a newish Mini parked nearby, set off up the hill as it's a nice place to see the sunrise, as we got up near the top my dog growled and I saw a shape in the darkness "I wont bite if he doesn't" said a voice that instantly reminded me of John Inman (Are you being Served) , "No Mate, my dog's OK, what about yours?" I replied, "I haven't got one, just having a walk to clear my mind, do you mind if I tag along with you?" came back the voice It seemed a bit odd but as far as I could see the guy was probably late 20s, about 5ft5in and slight, wearing a longish coat, I'm 6ft, and able to well take care of myself so I just said "OK" The usual stuff came up, Do you live near here?, Come here often? ect, I then asked if he'd had a heavy night and was walking it off, he replied "No, my partner is an absolute arse and it was best if I got out for a while", I replied without much thought "Yeah, done that myself", "Really I can't imagine you having a boyfriend" he replied, I laughed "No Mate, I meant with women", he replied "I've never had a problem with them, but nothing wrong with trying the other side I suppose...Have you?" I still don't know why I then blurted out that a guy had, without being asked, sucked me off during a MMF with his wife, but that was about it, he then asked me how it had come about and wanted all the details, recalling it as I told him got my cock swelling as we walked along, by now we were about halfway around and there is a big rock that I often sit on to get any stones out of my trainers, I sat down, pulled off a trainer and was shaking it out when he came out with "Can I give you one?, "WHAT?" I asked in disbelief, "Just a blowjob" he replied...I'm not sure how long I thought about it but my rising cock forced out the words "Yeah, OK" I quickly pulled my shorts down to my ankles and leaned back on the rock, my cock was now at about 90% erect, it's about 9 inches when rampant, he simply sank to he knees and started playing with my helmet with right hand while massaging my balls with his left, it was feeling really good, in no time my cock was as big as it can get and as hard as the rock my arse was on, he muttered something about it being nice and very delicately started sucking the head while wanking the shaft, it also felt like he was pull on my balls, there was NO way I could take much off this and in minutes I said "Fuck I'm going to cum" all he did was "hmmmmm" and wanked me harder, I just let it go, he swallowed the lot and literally milked every drop of cum out of me..."Fuck that was good I said when I got my breath back" he just smiled and said again "hmmmmm"... I saw he had a hard on in his jogging bottoms and surprised myself by saying "let me see your cock", we moved around and he laid back on the rock and pull down his pants past his knees, his cock was about 5 inches long but by comparison he had big balls and he was obviously shaved, I am not sure why but I pushed him flat on the rock with my left hand and held him firmly down while wanking his cock with my right, my first time I wasn't sure if I could suck him though....he sort of submitted and said "Please just make me cum"...I squeezed his cock hard abound the helmet and felt pre-cum on my hand, it was good lubrication, as I wanked him he was moaning and gasping, then as he cum he gripped my arm that was still holding him down, he shot loads of cum on his shirt and stomach and I returned the favour by holding him down as I milked him dry...We both started laughing as he pulled his pants up and had to pull his coat around his cum drenched shirt, by now the visibility was good my little dog cam back after a few shouts and whistles, and we walked back to our cars we swapped names but not numbers and both said that we'd do it again if we meet up...Been trying to wrap my head around what happened ever since, sucking or fucking a guy doesn't get me, perhaps I just, selfishly, don't care who sucks my cock?
