Just A Good-Natured Dick Sucking Prank Between Friends
The so-called "salt shaker prank" is fairly well established in the canon of practical jokes aimed at duping victims into mimicking the motion typically associated with oral sex.
But there is something genuinely touching about this particular execution of the tried-and-true faux-fellatio gag that instantly warms the cockles of one's heart.
Maybe it's their Kiwi accent; or maybe it's the way the prankster asks his mark, "so what's it like sucking dick?"
Either way, it's just nice to watch one friend trick another into imitating a blow job without having to overthink it.
