Even though I occasionally enjoy to "help out" for the casual cumshop task I HIGHLY recommend this post:

In which you can find the video tutorial (even though it's extremely easy) https://www.dropbox.com/s/emkzne80ijvjipv/Splooge.mp4
and the CumStyles 4.4 file

With this Styles for Photoshop you can do something really good quality without resorting to "donors". Of course you can easily do both things and have a perfect effect.
DISCLAIMER: the links I posted are virus free, as far as I could check. The only real thing you need is the file CumStyles 4.4. I didn't know the source myself but found it reliable.
REQUIREMENTS:
Photoshop
minimum level of hand-eye coordination
the CumStyles 4.4 file in the link
HOW:
GENERAL
Open your selected image
Create a layer and load the Styles from the PC
Use the brush tool to paint cum around the place
Use the smudge tool to make it look better
DETAILED (Sort of)
Open your selected image in Photoshop
Layer - New Layer
Layer Options - Styles - Load Styles (select CumStyles 4.4 in your PC)
Select the style better suited for the photo you are using (best ones as far as I am concerned are numbers : 3-4-5 for dark areas
8-9-10 for regular lighting but also good numbers 16 - 17 - 29 and Wet
Paint cum where you want
Use Smudge tool to create a better effect. This really make the difference
OTHER THINGS:
Experiment a little if you have time, this usually pays off.
It's really easy to use this "function" if you have Photoshop and are able to use the brush tool even only to a very basic level.
PIC is something done in 5-6 minutes with multiple layers to work with ease on different segments of magic-stuff ...
Have fun
Side note: the color you should usually use for the brush is "898989". It's basically a kind of gray, but you can experiment with other colors for different results
