I Jerked Off To A Nude Pic Of Myself That I Posted Online

I recently participated in a group nude swim for charity - something I've wanted to do for some time. The vibe was amazing, 400 people all naked and laughing going for a swim in the early morning. Charged up and confident after I got my friend to take a photo of me on the beach to celebrate - full body shot from behind, ass in full view. (Being a grower not a shower my front wasn't too impressive post swim). In a moment of cheekiness I posted it to my Instagram stories. I wasn't expected to experience the thrill that I did from posting it. I've always had a bit of an exhibitionist streak but as I kept checking the stats I couldn't help but get turned on by knowing who out of my friends had seen the photo. As is the nature of stories it eventually went away. 

Then a week or so later, I was working - Airdropping photos from my phone- and I saw the pic. I looked at it again and started thinking about how naughty it was to post it. It was easily the boldest thing I've ever done. -especially something my friends could see. I started thinking about who had seen it and got very turned on. I've always been told I have a cute ass and now some of my female friends know what it looks like. Some of my very hot female friends.... I couldn't focus on work. I just get thinking about it, a hard-on growing in my pants. My wife's very good friend had seen it, my sister in law has seen in, my young cute female friend had seen it and liked it. My good friend had seen it and said she'd love to do the swim next year. I suddenly took myself to the toilet. 

I pulled the photo off and started jacking off. I *do* have a cute bum. I wonder if my lady friends thought the same. Were they talking about it? Had they talked to each other? Had they saved it? Did they get themselves off to it? I imagined them all there when the photo was taken - me the centre of attention, them all looking at me, talking about me, reaching out to touch my ass....rubbing it.

I came in an absolute frenzy. 

I've never done anything like that before. I think it's unlocked something inside me....
