Well, of course I would love to do the same, while my wife and your husband do the photography.  My wife is 83 now and we can no longer buttfuck due to thin skin issues she has.  The asshole and pussy are nicely stretchable places as you well know, and aggravating when thin skin occurs.  We think it is hormone and vitamin deficiency, but not sure which ones.

Anyhow, I still buttfuck when I get the chance, which, drat, is not often.  But sometimes.  At last year's Burning Man, a friend, completely out of the blue, and she hadn't been drinking or anything, asked me if I'd like to fuck her in her asshole.  We had kind of played with each other a few times in the past but had never fucked.  She had already done cleanout enemas, and we a wonderful time in my large Kodiak tent, very intense orgasms.
