Guy on right also badly needs fucking - hard!
He has every reason to smile, though I doubt if anyone has noticed, all being transfixed by his unashamedly blatant horn.
Are they all posing with tongues not quite touching cocks, or did camera click a second too early? The first, I reckon.
Feeding time - and judging from the wet marks on his tee-shirt, a lot has already missed its target, which was a bit of a waste.
Good, natural, casual shot.
