8 XXX : painal

Is anyone else getting tired of these tiny gifs with no sound, or is it just me? They all just end up with comments asking for the source.
I have an ex who loved this. You could be behind her while she was on all fours, and just ram it in on the first thrust, no lubrication, except a little spit on the head of your dick, (which any girl will tell you: It don't do nothin' for her,) just so you didn't break it in half.
Is there a subreddit for that move?
Source?
THE SAUCE!! WHERE IS THE SAUCE!!??
