I don't believe that I have seen this method here before. After years of regular masturbation, I combined a couple of techniques. I have long used a condom when I get off. Adding some lube to the inside, a condom hugs me tight, the lube keeps things slick and there is no clean up mess. Additionally, for me just the act of rolling a condom down my dick is synonymous with sex and getting off.
The difference in this method is the use of a condom AND pillows. First, after adding some lube to the inside of a condom, put it on your erect dick. Stroking yourself this way is quite pleasurable on its on. But now we add an additional aspect. I stack two bed pillows on top of each other, then put my condom covered member on top of the second pillow. Now add a third pillow on top of your dick and lay down. You should be able to hump the pillow stack much as you would a woman. The feeling is exquisite You move between the pillows but more importantly, you move inside the lubed condom - the equivalent of a wet pussy. Continue humping the pillow stack (added by porn or your fantasies) until you come.
As I said, no mess to clean up. Just remove and discard the condom.
I encourage you to experiment with condoms. They add different dimensions to masturbation. have fun!
