beg for it
It's the opening sequence, when warden Jack Wrangler is forcing a blow job out of hot, bearded, prisoner Ray Medina (who, alas, I've only seen in two other films, Gayracula, and Rawhide, and is credited here as R. W. Stone). In fact, the whole film is full of hot bearded cocksuckers: the best, Al Parker, of course; plus Medina; Al's real-life boyfriend Steve Taylor; a scruffily bearded Duff Paxton with his furry chest; and reddish-bearded Sam Benson who blows Wrangler, then gets fucked by him in order to distract the guard while Parker and Seagers escapes. If you like hot bearded cocksuckers (who doesn't!), you should see this film (or drop by my apartment).
