I have some experience with freezing cum to overcome the mental block after coming and also I can save more than one load which is necessary to make this idea cum true

Now I'm thinking how to make this happen and hope to get some feedback and ideas by you guys

One idea is to synchronize myself with a porn video so everytime a guy comes, one of my loads will hit me at the same place as shown in the vid. It would be best if I got some video link by somebody after I started so I dont know the video which makes it even more exiting not to know when and where somebody shoots a load.
One of the open questions is what I can use to shoot the thawn cum with.
Any ideas, comments?
