Although it doesn't have a creampie at the end, there is a sort of older quality nun video that is pretty awesome made by Xalas. It is called "Bless His Sinful Cock Retold Chapter 1", not sure if he ever got around to making Chapter 2, but that Chapter 1 is pretty hot. Now that I think of it, there is a creampie right before the final scene, so it is possible what you're looking is the original version to this video, not the retold version? But you get the some extra naughty nun fun at the end of the retold version. I tried to upload the video I have, but it says it is too large for the F95 server. Do a quick google search for the video, you'll find it.
