Thats an awesome pic, and I'm hoping someone will post more from the series. There has to be more....
Best guess is thats its from a "party hardcore" type series, but I don't know. I considered that the boner was photoshopped, but probably not.
Could be pro stuff - very likely. CFNM related or, like I said, "party hardcore"
BTW - looks like a flickr.com filename. Any link to a gallery?
..and I'm still not ruling out a doctored pic...
