Anal Fingering on LetMeJizz
One partner pins the other open and presses a single slick finger past the rim, controlling how deep and how fast the whole way. The power lives in that grip, a slow stretch used to tease, loosen or completely undo someone who can only lie there and take it. Often it runs as the warm-up before something bigger, the prep itself drawn out until it becomes the main event.
