How they aren't locked in the throes of passion at that moment is simply beyond me. John wants to devour that neck. Lounging on the floor, their bodies pressed together, good thing they remembered there were people around or they might've had a lot to explain at their next press conference. Or not, if anything maybe that would've made things clearer to everyone.
A million '60s women had their hearts shatter when they saw this photo, then wrote in their diaries that instead of fucking John or Paul, their new obsession was to watch them slowly worship each other until they were both panting, exhausted, and fully satisfied (which would then be incorporated into their next single--it was John & Paul, after all.)
