May be real, may not.
I say lay off the guy, you're acting like a bunch of horny teenager boys that saw your first naked piece of pussy, or worse, actually touched it!
If the guy doesn't want to post a pic or the person he promised it to if obtained, asked that pics not be posted, then it's none of your, mine, or anyones business except those involved.
If it turns out not to be real, and there are a lot of doubters, so what. the doubters were right. Otherwise, take it easy and be patient. It's all good.
