Some of the photos are of me and a few were even taken on this day by cellphone camera. But the others are just photos found on the Net. I obviously didn't get a photo the stranger who caught me naked and jerking -- although now I wish I had asked him to take a picture.
The island has a embankment around the perimeter but the entire center is at a much lower level so you have to climb up stairs to reach the banks -- this means that many people don't actually see over perimeter as they walk around the island. There were some other people (partly clothed) sunning themselves further on down this side of the island so I decided to strip down to undies and catch some rays.
One guy was wearing only a fundoshi - the wrap around loin cloth that used to be traditional Japanese underwear and now is typically only worn during festivals. Seeing him almost nude inspired me.
It wasn't long before I went further and took off all clothes. It was a grassy slope leading down the bank and I was sitting under a tree so it was not so clearly obvious to pedestrians who went up the stone stairs 30 ft behind me that I was nude. But if someone came off the walkway along the embankment and walked down the grassy slope, they get a good idea. So it was not a blatant act of flashing .. I was sunbathing nude, but that would only be clear to someone who was curious enough to approach me. There were boats that passed in the harbor which might have been able to see more if the driver or passengers were interested -- also pedestrians who walked along the bridge walkway could catch a glimpse of a nude form in the grass but they could not clearly identify me unless that had binoculars (or a zoom lens) since the bridge was far off. I stayed for nearly two hours -- not much happened.
Another foreign guy (not Japanese -- I think he was European) came up and seemed interested. He sat down about 50 ft away and sometimes gave me a look. Later he got up and came over to ask a question about directions, I was pretty sure that he was not going to scream in panic and just wanted to get a closer look so I really didn't cover up. But he was pretty much on the level and didn't comment on my nudity or really show that much interest either. So he moved on after we chatted just a minute.
Well, I found that very stimulating to be sitting there nude in a public park in Tokyo -- admittedly it was rather isolated, but it was one of my first flashing experiences. I never consider being naked on nude beaches as flashing - -although I suppose if you are showing a hard cock in the dunes like you are baiting a cocksucker with a hook, line, and sinker -- that might count. I've done that.. but this was the first time to be completely naked in front of strangers (few and far between ) in a public park where most people would NOT expect nudity.
It was not too long afterward that I noticed a younger Japanese guy (maybe 20) walking along the embankment on my right. There was a concrete gulley (used to drain the central plain of the island) that was too wide to cross between us. He noticed me and then he sat down on a bench about 75 ft away but kept looking over at me, obviously intrigued. I lay back at one point so that he could get a real glimpse of cock and pubic hair so he could confirm I was really nude. That would either get his juices going or he'd just leave if he were not interested in seeing dick. Sure enough, he got up but with an obvious glint of real interest in his eyes. So he made his way back up the ridge, and then proceeded down in the center of the island and disappeared. In a short time, he reappeared at the top again and looked around, seeming to decide if it was all right to approach me.
After all, I was this naked foreign (white) guy sititing in the grass on a warm summer's day not far from downtown Tokyo. I don't think it was something he had ever seen -- neither was it something I had ever done -- so blatantly. He kept his eyes on me -- wanting to get a look at my cock which had now stood up hard and erect - since his interest was so obvious. I was starting to drip pre-cum as he made his way down the slope and around the tree and then stopped in front of me - standing between me and the bridge in the distance.
He sat down on one of the poles that supported the single length of chain that roped off the edge of the bank, staring at my erection. He was definitely cute and I could see the lust in his eyes -- I was really excited and as he sat there I could not help but reach for my hard cock and stroke it. He moved up closer and stood over me as I stroked more. He braced my legs with his and pushed them wider so that he could get a better look at my ass crack too. He urged to me on -- asking in Japanese, ' Ii kimochi?' (Does that feel good?) I grunted in response and he asked me to go on beating, 'motto yatte'. (Do it more). I wanted him to reach down and touch me but he kept glancing to his left and right down either side of the embankment. Still he was encouraging me to keep stroking, 'ii nah".. "kimochi?". "Yatte." I could not keep quiet because it was SO hot to be watched by a complete stranger in a public park who was clearly enjoying the show. I was moaning too and responding to his taunts I pushed against his legs and raised up to reach for his cock through his loose athletic pants, but he pulled upright. Maybe he was straight or maybe he was too cautious to do anything himself, but he was certainly very interested in watching me jerk my cock which was copiously leaking clear pre-cum across my belly. It didn't take long at this point before I was ready to let my cum fly.
The guy watched more intently and bent over to get a closer look when my spunk started to splatter my stomach and chest. When I was done, he gave me a smile, checked around to see if we had been observed by anybody else. He adjusted his own erection in his pants to make it less obvious and then walked away. It took me a few minutes to get cleaned up but I decided not to press my luck so I got dressed and left shortly after that. It was my first public masturbation for a stranger -- it started me on my 'career' as a cock flasher, I guess. But so far, I've not had quite a similar experience. I have only one regret -- not asking him to take a picture of me jacking in front of him with my cell phone. I have some cell phone cam photos taken then but they don't show him.
