Set of 13 gifs by Muga showing close-up of character's face followed by a still close-up shot of their genitalia.
The gifs have been edited to show the face and genitalia portions simultaneously side by side.
Some gifs include two separate shots of the genitals, first closed and then spread. In these cases they have been turned into their own animated gifs.

Edit: fixed the closed/spread gifs

Edit 2: Added a variant set of all the gifs with genitalia on the left and faces on the right.

Nice, these sort of pics aren't all that common.
